Print-on-demand using AI-generated artwork is one of the few online income tactics where the legal position is unusually clear and unusually bad, and where almost nobody selling courses about it mentions the legal position at all.
The mechanics are simple. You generate images with a text-to-image model. You upload them to a print-on-demand supplier or marketplace. When a customer orders, the supplier prints the design onto a poster, a mug, a t-shirt or a phone case, ships it, and pays you the difference between the retail price and their base cost. You never touch inventory. Your marginal cost of producing a new design is close to zero.
That last sentence is the whole story, in both directions. It is why the barrier to entry is low, and it is why the barrier to entry is low for everyone else too.
This page covers what you can and cannot legally claim to own, what each platform's published policy actually says, what the base costs and margins really are with figures taken from the suppliers' own pages, why the saturation problem is structural rather than temporary, where the trademark landmines are, and what you have to disclose and to whom. Where a number could not be confirmed from a primary source, it says so.
There are three distinct models, and they have different economics and different failure modes.
Almost everyone starts with the first or second model. Almost all the failure happens there too, for reasons the rest of this page sets out.
In January 2025 the United States Copyright Office published Part 2 of its report on copyright and artificial intelligence, dealing specifically with copyrightability of AI outputs. Its conclusions are stated plainly in the executive summary:
The Office's reasoning on prompts is worth reading closely, because it forecloses the most common workaround people attempt. The report says: "Prompts essentially function as instructions that convey unprotectible ideas. While highly detailed prompts could contain the user's desired expressive elements, at present they do not control how the AI system processes them in generating the output."
Writing a longer prompt does not help. Writing a 400-word prompt does not help. The Office explicitly considered that argument and rejected it, drawing on joint-authorship case law: "The provision of detailed directions, without influence over how those directions are executed, is insufficient."
Two months later, on 18 March 2025, the D.C. Circuit affirmed the human authorship requirement as a matter of statutory law in Thaler v. Perlmutter, holding that "the Copyright Act of 1976 requires all eligible work to be authored in the first instance by a human being." That case concerned a machine listed as the author, which is a narrower question than yours, but it removed any remaining argument that the Copyright Office is inventing a requirement Congress did not impose.
The practical translation: if your listing image is an unmodified model output, you have no copyright in it. Not weak copyright. None.
The report is not a blanket refusal. It identifies three routes to protection, and each has a specific shape.
Note what that annotation does. It protects your drawing. It does not protect the rendering, lighting, shading or texture the model added. If a competitor copies the finished image, you are asserting rights only in the perceptible human parts.
The counter-example in the same report is Suryast, where a photographer supplied his own photograph and instructed an AI system to apply the style of Van Gogh's The Starry Night. The Review Board refused registration because the applicant "exerted insufficient creative control" and, unlike Rose Enigma, the output did not clearly show the copyrightable input work.
The report also notes that tools which "enable the user to control the selection and placement of individual creative elements" sit in a different category from prompting alone, with copyrightability decided case by case under the Feist originality standard.
If you do decide to register something, the Copyright Office's registration guidance (Copyright Registration Guidance: Works Containing Material Generated by Artificial Intelligence, published at 88 Fed. Reg. 16190, 16 March 2023) imposes an affirmative duty. Its words: "applicants have a duty to disclose the inclusion of AI-generated content in a work submitted for registration and to provide a brief explanation of the human author's contributions to the work."
Mechanically, you must use the Standard Application rather than the Single Application, describe the human contribution in the "Author Created" field, and exclude AI-generated content that is "more than de minimis" in the "Limitation of the Claim" section under "Material Excluded". You are told not to list the AI tool or its vendor as an author.
The consequences of not doing this are specific. The guidance states that applicants who fail to update the record "risk losing the benefits of the registration," that the Office may cancel a registration where essential information "has been omitted entirely from the application or is questionable," and that "a court may disregard a registration in an infringement action pursuant to section 411(b) of the Copyright Act if it concludes that the applicant knowingly provided the Office with inaccurate information, and the accurate information would have resulted in the refusal of the registration."
That last point is the sharp one. A seller who quietly registers AI output as their own painting has not gained protection. They have created a document that can be used against them, and they have signed a statement to a federal agency.
Registration fees, from the Copyright Office fee schedule: 45 US dollars for a single application (one work, one author, not made for hire, filed electronically), 65 US dollars for the Standard Application, 125 US dollars on paper. Since AI-assisted works require the Standard Application, budget 65 US dollars per registration, and note that this is per work, not per portfolio, unless you are registering a genuine collection.
Jurisdiction matters here more than in almost any other online income tactic, because you may be selling into markets whose law differs from your own.
On its face this is more generous than the US position. In practice it is untested: the UK Intellectual Property Office's 2022 consultation outcome found there was no case law applying the provision to AI, concluded that "it is unclear whether removing [protection for computer-generated works] would either promote or discourage innovation," and left the law alone. A further UK consultation on copyright and AI opened in December 2024. Do not build a business on the assumption that section 9(3) definitely covers a Midjourney output; nobody has litigated it.
Hong Kong (Copyright Ordinance section 11(3)), India (Copyright Act 1957 section 2(d)(vi)) and New Zealand (Copyright Act 1994 section 5(2)(a)) have similar computer-generated works provisions, with the same absence of authority on how they apply to generative models.
If you are selling globally (and print-on-demand marketplaces are global by default) you are operating under several of these regimes at once. Take local advice before making any claim about ownership in a jurisdiction you do not live in.
Every major generator says something reassuring in its terms. Read the qualifier.
Midjourney's Terms of Service say: "You own all Assets You create with the Services to the fullest extent possible under applicable law." In the United States, applicable law is what the Copyright Office and the D.C. Circuit have just described. The clause transfers whatever Midjourney has; it cannot create a copyright that does not exist.
Midjourney's published plan prices are 10, 30, 60 and 120 US dollars per month for Basic, Standard, Pro and Mega, with a 20 per cent discount for annual commitment paid upfront (96, 288, 576 and 1,152 US dollars per year). Unlimited generations in Relax Mode start at the Standard plan. Stealth Mode starts at Pro, which is 60 US dollars a month or 48 US dollars a month billed annually.
For a seller, that distinction maps to the two risks precisely: indemnity protects you on the defensive side, copyright would have protected you on the offensive side. Only one of those is available.
Here is where the copyright position stops being an abstraction.
Under 17 U.S.C. section 411(a), "no civil action for infringement of the copyright in any United States work shall be instituted until preregistration or registration of the copyright claim has been made in accordance with this title." You cannot sue without a registration. You cannot obtain a registration for purely AI-generated material. Therefore you cannot sue anyone in a US federal court for copying it.
Under 17 U.S.C. section 412, even where a registration exists, no statutory damages or attorney's fees are available for infringement that began before registration, unless registration followed within three months of first publication. Statutory damages under 17 U.S.C. section 504(c) run from 750 to 30,000 US dollars per work, rising to 150,000 US dollars for wilful infringement and falling to 200 US dollars for innocent infringement. Without registration you are limited to actual damages and the infringer's profits, which for a poster listing that sold four copies is not a number that pays for a lawyer's first phone call.
That is the offensive picture. The defensive picture is worse, because the same design you cannot protect is one that somebody else can copy and list on the same marketplace within an hour, with no legal consequence to them.
What about DMCA takedowns? A notice under 17 U.S.C. section 512(c)(3) requires a statement, under penalty of perjury, that you are the copyright owner or authorised to act for them, and a good-faith belief that the use is not authorised. Filing takedowns against copies of material you do not own copyright in exposes you to liability under section 512(f) for knowing material misrepresentation. Marketplaces also count bad notices against your account. This is not a theoretical constraint; it is the reason experienced sellers in this niche do not bother filing.
Redbubble's own help centre is candid about the limits of platform enforcement. Its article on why similar works remain live explains that content is removed when "identified as infringing in a legally valid takedown notice," and that "we generally don't go looking for similar works to remove from the marketplace." Platforms respond to valid notices. They do not police lookalikes on your behalf.
What is left? Three things, all weaker than copyright.
- Trade dress and brand. A consistent shop identity, a registered word mark, a recognisable product line. Trademark protects source identifiers, not pictures, but it is the one right in this business you can actually own and register.
- Contract and platform terms. Marketplaces will act on duplicate-listing and account-abuse policies where the copying is wholesale, though enforcement is inconsistent and unappealable.
- Speed. Being first and being cheapest to reprice. This is not a legal right, it is an operating posture, and it works only until someone with more upload capacity notices your listing.
If your business plan requires that a design remain exclusive to you, this tactic does not support that plan.
The three biggest venues have materially different published rules, and the differences are not where most people assume.
Etsy
Etsy allows AI-generated art and has a specific published disclosure rule. Etsy's Creativity Standards state that sellers "must disclose within their listing description if an item is created with the use of AI," and its help documentation repeats that "seller-prompted AI creations must disclose the use of AI." Etsy's seller handbook describes its stance as allowing "AI-generated art where a seller utilizes their unique creative lens and abilities, in addition to being transparent about their process."
Etsy sorts listings into categories, and AI-assisted work belongs to "Designed by a seller". Described in Etsy's own materials as "Original designs by a seller (or seller-prompted AI art) offered as a digital download or produced/printed by a third-party". Rather than "Made by a seller." If you use a print-on-demand supplier, that supplier is a production partner and Etsy requires separate disclosure of it: "Sellers must disclose that an item is made by a production partner, and provide accurate information about where the item will ship from."
So an Etsy print-on-demand listing built on generated art carries two disclosure duties, not one: the AI disclosure in the description, and the production partner disclosure in the listing's production partner field. Etsy does not publish a fixed penalty schedule for a missed disclosure. Listing removal and account-level action are both within its stated discretion.
Note also that Etsy blocks automated access to its own policy pages, which means the exact wording can change without any easy way to diff it. Check the live Creativity Standards page before you rely on the wording quoted here.
Etsy fee structure, taken from Etsy's 2025 annual report on Form 10-K, filed 19 February 2026, which is the most reliable primary source because it is a filing made under securities law:
- Listing fee: a fixed 0.20 US dollars per item listed, recognised over a four-month listing period, non-refundable.
- Transaction fee: 6.5 per cent per completed transaction, "inclusive of shipping fees charged."
- Offsite Ads: a further transaction fee of "12% or 15% of the value of a sale based on the seller's volume of sales" where the sale came from an Etsy-placed advertisement on a third-party platform. Etsy's help documentation states the Offsite Ads fee "for any individual order will never exceed $100 USD."
- Payments processing fees are charged separately and vary by country.
The exact per-country payment processing rate could not be confirmed from Etsy's own fee page, because Etsy returns HTTP 403 to automated requests. Check the rate for your country in Etsy's Fees and Payments Policy before modelling margins.
Amazon Merch on Demand
Amazon Merch is application-gated. You submit a request and, in Amazon's words, "we will provide you with an expected timeframe for a decision and we will notify you of the decision via email." Approval is not automatic and the queue is not published. The programme is non-exclusive: Amazon confirms you may submit the same design elsewhere.
Amazon Merch has no published AI disclosure requirement. Its Content Policies page prohibits illegal or infringing content, offensive or controversial content, and a list of other categories, and says nothing at all about disclosing the use of generative tools. That is a real and checkable difference from Etsy, and it matters if you are choosing where to list. It is also not the same thing as approval: the IP warranties still apply in full.
What the Content Policies do say, directly relevant here, is that Amazon prohibits "content incorporating intellectual property (such as trademarks, copyrights, or the name or likeness of others) that you do not have the right to use," and that this "may include text, visual representations of designs, patterns, products or other objects (for example, certain car models), or photographs." Amazon then links to the trademark registers for each of its marketplaces (USPTO for the US, UKIPO, EUIPO and TMDN for the UK, DPMA for Germany, J-Plat Pat for Japan) which is an unusually direct instruction to search before you upload.
The consequences of getting it wrong are stated in the same document: Amazon "may take corrective actions, such as immediately suspending or terminating Content Creator privileges, removing listings, terminating the business relationship, or permanently withholding payments."
Royalty structure. As set out on Amazon's own Royalties page, your royalty is your product's offer price less applicable tax and less Amazon's costs, with a multiplier applied based on your royalty group. In the US store there are three groups:
- Creator: standard rates.
- Plus: for creators who "actively drive at least 15% of unit sales with non-organic traffic," paying 2x the Creator rate.
- Premium: for those driving at least 35 per cent of unit sales with non-organic traffic, paying 2.16x the Creator rate.
Eligibility for Plus and Premium requires selling a minimum of 10 units per month in the US store. Groups update monthly on a trailing two-month average. Amazon states that "royalty rates for sales outside of the US store remain unchanged," and that accounts with no sale in over a year may be moved to inactive status.
The Creator rates for a standard t-shirt in the US store, from Amazon's published examples:
- 15.99 US dollars list, 0.96 US dollars royalty
- 17.99 US dollars list, 1.70 US dollars royalty
- 19.99 US dollars list, 2.44 US dollars royalty
- 21.99 US dollars list, 3.18 US dollars royalty
- 23.99 US dollars list, 3.92 US dollars royalty
- 25.99 US dollars list, 4.66 US dollars royalty
Two things fall out of that table. First, at the popular 19.99 US dollars price point your royalty is 12.2 per cent of the list price. Second, every 1 US dollar you add to the price adds 37 cents to your royalty. Amazon keeps 63 cents of every marginal dollar. Raising price is therefore a weak lever unless volume holds up, which at higher prices it usually does not.
Some product lines are far worse. Amazon's published example for the Comfort Colors Adult Sweatshirt in the US store shows a 35.99 US dollars list price returning a 0.29 US dollars Creator royalty: under 1 per cent of the list price. The same product at 39.99 US dollars returns 1.69 US dollars. If you are listing on Merch without reading the royalty table for the specific garment, you can spend an afternoon producing listings that are structurally incapable of paying.
Amazon also requires 300 dpi PNG files sized to the 15 by 18 inch printable area, and states in the Services Agreement that it is the seller of record with "sole discretion to determine price, availability, distribution channels, and terms of sale."
Redbubble
Redbubble does not publish a dedicated AI-generated content policy article in its help centre. A search of its help centre in August 2026 for "artificial intelligence" returned a single unrelated match. That absence is not the same as permission; Redbubble's intellectual property policy still requires that you have the rights to what you upload, and its help centre states plainly that "the Redbubble marketplace is a place to display and sell your original artwork."
What Redbubble does publish, and what matters far more to an AI-art seller, is its account classification criteria. Redbubble's help article on how accounts are classified (updated 8 July 2026) lists among its considerations:
- "Origin of the artwork (i.e., uploading high volumes of low-effort or repetitive designs and using unmodified vector packs, clip art, or royalty-free images)"
- File quality
- Consumer appeal
- Tag spamming or inaccurate information in titles and descriptions
That first bullet describes the standard AI-print-on-demand workflow almost exactly. Redbubble is not banning AI art; it is charging you more for behaving like a bulk uploader.
The fee consequence. Redbubble's account tiers determine the platform fee deducted from gross earnings each payment period (help article updated 31 July 2026):
- Standard artists: 50 per cent platform fee on monthly earnings
- Premium artists: 20 per cent platform fee
- Pro artists: no platform fee
Fees for Standard and Premium artists are capped at 150 US dollars, 150 euros or 150 pounds per payment period. Separately, an excess markup fee applies: Redbubble states that no fees apply to product markups at or below 20 per cent, and that a 50 per cent fee is deducted from gross earnings made above that threshold, for Standard and Premium artists. Pro artists pay neither.
Redbubble's default artist margin is 20 per cent of the base price; its own worked example states that "20% of the $20 base price means you earn an artist margin of $4.00 (before account fees)." On a Standard account that 4.00 US dollars becomes 2.00 US dollars after the 50 per cent platform fee. On a Premium account it becomes 3.20 US dollars. On Pro it stays at 4.00 US dollars.
The payment threshold was lowered on 1 July 2026 from 20 to 10 US dollars, pounds or euros. Below that, earnings roll over.
Printful, Printify and the other white-label suppliers
These are suppliers, not marketplaces. They do not send you customers. Their published pricing, checked 5 August 2026:
Printful. Free plan at 0 US dollars per month with access to its catalogue and integrations. Printful Growth at 24.99 US dollars per month, waived once you reach 12,000 US dollars per year in sales, giving "up to 33% off product pricing," 9 per cent off product branding and 25 per cent off sample orders. Sample base prices:
- Enhanced Matte Paper Poster: from 6.25 US dollars at the smallest size; 10.25 US dollars at 12 by 18 inches; 11.50 US dollars at 18 by 24 inches; 15.95 US dollars at 24 by 36 inches
- Unisex Staple T-Shirt (Bella + Canvas 3001): from 10.75 US dollars
Add-on costs Printful publishes: printed inside apparel labels 0.99 US dollars each, printed outside labels 2.49 US dollars each, premium images from Getty 1 US dollar per image per placement per item sold, embroidery digitisation 2.95 to 6.50 US dollars one-off per design, extra embroidery placements 2.95 US dollars.
Shipping is charged separately on every order and varies by destination and category. Printful's rate table renders for the visitor's own region, so the US domestic poster rate could not be captured here; the rate shown for a single shirt to Malaysia was 11.99 US dollars with 6.00 US dollars per additional product. Pull your own region's figures from Printful's shipping page or its downloadable CSV before pricing anything.
Printify. Free plan with 5 stores. Premium from 39 US dollars per month billed monthly, or from 24.99 US dollars per month billed annually, giving "up to 20% discount on all products" and up to 33 per cent on new products. Printify's own profit calculator on the pricing page shows a fulfilment cost of 8.77 US dollars for a Unisex Jersey Short Sleeve Tee, excluding shipping and taxes. Printify works through 90-plus print providers, which means base cost for the same product varies by which provider you route to. The single largest controllable variable in Printify's economics.
Both suppliers charge you at the moment the order is placed, on your stored payment method. You are float-negative on every order until the marketplace pays you out.
The unit economics, with real base costs
A worked poster example on Etsy
Assume an 18 by 24 inch matte poster, sold to a US buyer at 42.00 US dollars with shipping built into the price, fulfilled by Printful, listed on Etsy.
- Retail price: 42.00 US dollars
- Printful base cost, 18 by 24 inch Enhanced Matte Paper Poster: 11.50 US dollars (confirmed)
- Printful shipping, US domestic, posters: estimated at 10.00 US dollars. This could not be confirmed: Printful's rate table geolocates to the visitor's region. Verify for your own selling region.
- Etsy listing fee: 0.20 US dollars (confirmed; this is per listing per four months, so it is 0.20 US dollars only if the listing sells exactly once in that window)
- Etsy transaction fee at 6.5 per cent of 42.00 US dollars: 2.73 US dollars (confirmed rate)
- Etsy payment processing: estimated at 1.51 US dollars. Etsy's per-country rate could not be confirmed from its own page.
Total costs: 25.94 US dollars. Gross margin: 16.06 US dollars, or 38 per cent of the retail price.
Now add one variable that catches new sellers. If that sale was attributed to Offsite Ads, Etsy charges 15 per cent of the total order amount for sellers below its volume threshold. A further 6.30 US dollars, taking margin to 9.76 US dollars, or 23 per cent. Sellers above the volume threshold pay 12 per cent and cannot opt out.
Then subtract the cost of the design tool, any advertising you ran yourself, the sample you should have ordered, and income tax. A 42 US dollar poster is not a 42 US dollar business.
A worked Amazon Merch example
Standard t-shirt at 19.99 US dollars in the US store, Creator group: 2.44 US dollars royalty per sale, confirmed from Amazon's published table. No listing fee, no monthly fee, no fulfilment cost, no advertising unless you buy it.
To reach the Plus group you must drive at least 15 per cent of unit sales through non-organic traffic and sell at least 10 units a month, at which point the same shirt pays 4.88 US dollars. Premium, at 35 per cent non-organic and the same volume floor, pays 5.27 US dollars.
The design of that scheme is worth noticing. Amazon is paying you roughly double to bring your own traffic. If you can bring traffic, you are already most of the way to running your own storefront where you would keep far more than 5.27 US dollars on a 19.99 US dollar shirt. If you cannot bring traffic, you are on 2.44 US dollars and competing on Amazon's search results page against everyone else who also cannot.
A worked Redbubble example
Product with a 20 US dollar base price, default 20 per cent markup, giving a 4.00 US dollar artist margin per Redbubble's own example. After account fees:
- Pro tier: 4.00 US dollars
- Premium tier: 3.20 US dollars
- Standard tier: 2.00 US dollars
New accounts are classified after first-time setup, and the classification criteria explicitly disfavour high-volume, low-effort, repetitive uploads. A bulk AI portfolio is the profile most likely to land on Standard, which is the tier paying half. Raising your markup above 20 per cent to compensate triggers the 50 per cent excess markup fee on earnings above the threshold, which is precisely why that fee exists.
The saturation problem, quantified
The saturation argument is usually made vaguely. It can be made with numbers.
From Etsy's 2025 Form 10-K: as of 31 December 2025 the Etsy marketplace had 5.6 million active sellers, 86.5 million active buyers, and "more than 100 million items for sale." Etsy marketplace gross merchandise sales for 2025 were 10,460.7 million US dollars.
Divide GMS by active sellers and you get roughly 1,868 US dollars of gross merchandise sales per active seller per year. About 156 US dollars a month, before Etsy's fees and before the cost of goods. That figure is a mean, and it misleads in both directions, which is exactly why it should be stated with its caveats rather than quoted as an average income.
It understates in one respect: Etsy defines an active seller as "a seller who has had a charge or sale in the last 12 months." A charge counts. Somebody who listed four items, paid 0.80 US dollars in listing fees and sold nothing is an active seller in that denominator. The denominator is therefore inflated with non-businesses.
It overstates in a more important respect: marketplace revenue distributions are extremely right-skewed. A small number of shops account for a large share of GMS, which drags the mean far above the median. Etsy does not publish the distribution of GMS across sellers, so the median cannot be calculated from public filings. Anyone quoting you a "typical Etsy seller income" is either using this mean without saying so, or making it up.
The structural point behind the arithmetic: there are more than 100 million items listed and 86.5 million buyers. Item count is growing faster than buyer count, and generative tools are the reason. When the marginal cost of a new design falls to near zero, supply expands until the marginal listing earns approximately nothing. That is not a temporary condition caused by a trend; it is the equilibrium the technology produces.
Every platform has responded with a friction mechanism, and once you see them as friction mechanisms they make sense:
- Etsy's 0.20 US dollar listing fee, charged per item per four months, is a tax on spray-and-pray. Ten thousand listings costs 2,000 US dollars every four months whether they sell or not.
- Redbubble's account tiers charge bulk uploaders 50 per cent instead of nothing.
- Amazon Merch gates entry by application: you request an account and wait for a decision, and Amazon publishes no approval criteria. Amazon is also widely reported to cap how many designs a new account may keep live, expanding that allowance as you sell. That upload-cap system could not be confirmed from any Amazon-published page: it is not described in the Royalties page, the Content Policies, the Services Agreement or the public FAQs, and every specific tier figure in circulation traces to third-party blogs. Treat any number you read for it as unverified.
The tactic that "works" is therefore not "generate a thousand designs." Every platform has already priced that in.
Trademark risk lives in your prompts
Copyright is the risk you cannot use. Trademark is the risk that can actually cost you money, and generative models walk into it eagerly.
The mechanism is straightforward. Ask a model for a design in the style of a well-known franchise, or featuring a recognisable character, mascot, logo, catchphrase, car silhouette or celebrity likeness, and it will produce something close enough to be actionable. The model has no knowledge of the trademark register. You do, or you are expected to.
Registered trademark exposure. Under 15 U.S.C. section 1117(a) a successful plaintiff may recover the defendant's profits, the plaintiff's damages and costs, and a court "may enter judgment... for any sum above the amount found as actual damages, not exceeding three times such amount," with attorney fees available in exceptional cases. Where counterfeit marks are involved, section 1117(c) allows the plaintiff to elect statutory damages of "not less than $1,000 or more than $200,000 per counterfeit mark per type of goods or services," rising to "not more than $2,000,000 per counterfeit mark per type of goods or services" for wilful use. Those are per mark per goods type, not per sale.
Copyright exposure from someone else's characters. Distinct from the question of whether you own your own output. If your generated image reproduces protected expression from a copyrighted character or artwork, statutory damages under 17 U.S.C. section 504(c) run from 750 to 30,000 US dollars per work infringed, up to 150,000 US dollars if wilful.
Right of publicity. Using a real person's name or likeness on merchandise engages state-law publicity rights in the United States, which vary substantially between states in scope, duration and post-mortem coverage, and separate regimes in other countries. There is no single national rule. Check the law of the state or country where you are selling.
The subtler trap: ordinary phrases. Trademark registers are full of short, generic-sounding phrases registered for clothing in International Class 25. A slogan that seems obviously unownable may be registered by somebody who will send a takedown. Amazon's Content Policies link directly to the searchable registers. USPTO for the United States, UKIPO, EUIPO and the TMDN common register for Europe and the UK, DPMA for Germany, J-Plat Pat for Japan. And the practical habit is to search every phrase in the relevant class before uploading. This takes about ninety seconds and is the highest-return ninety seconds in the whole workflow.
Registering your own mark. If you want to build a brand that survives this business, USPTO fees as of the January 2025 fee structure are a base application fee of 350 US dollars per class of goods or services, plus a 100 US dollar per class surcharge for insufficient information, plus a 200 US dollar per class surcharge for using the free-form text box instead of the Trademark ID Manual, plus 200 US dollars per additional 1,000 characters in that box. Intent-to-use applications add 150 US dollars per class for a statement of use and 125 US dollars per class for an extension. Maintenance is 325 US dollars per class for the five-year declaration and 650 US dollars per class for the combined ten-year renewal. Fees differ in every other jurisdiction.
Three separate disclosure regimes
People conflate these. They are independent of each other and you can comply with one while breaching another.
Platform disclosure. Etsy requires disclosure of AI use in the listing description and separate disclosure of the production partner. Amazon Merch's published content policies require neither. Redbubble publishes no dedicated AI disclosure rule. These are contractual, enforced by listing removal and account action, and they change without notice.
Copyright Office disclosure. As set out above, a duty to disclose AI-generated content on any registration application, with cancellation and section 411(b) consequences for failing to. This applies only if you register, but it applies absolutely if you do.
EU AI Act transparency obligations. Article 50 of the AI Act became applicable on 2 August 2026. Two provisions are relevant, and they land on different parties.
Article 50(2) obliges providers of AI systems generating synthetic audio, image, video or text to "ensure that the outputs of the AI system are marked in a machine-readable format and detectable as artificially generated or manipulated." That duty falls on the model provider (OpenAI, Midjourney, Adobe) not on you. Its practical effect on a seller is that generated files may carry provenance metadata, which platforms can read.
Article 50(4) obliges deployers of AI systems that generate or manipulate image, audio or video content constituting a deep fake to disclose that the content has been artificially generated or manipulated. It contains a carve-out: "Where the content forms part of an evidently artistic, creative, satirical, fictional or analogous work or programme, the transparency obligations set out in this paragraph are limited to disclosure of the existence of such generated or manipulated content in an appropriate manner that does not hamper the display or enjoyment of the work."
A decorative abstract poster is not a deep fake and Article 50(4) does not obviously bite. A design depicting a real, identifiable person in a fabricated scene plausibly is, and the artistic carve-out reduces but does not remove the duty. This is a new and untested provision; if you sell into the EU and your designs depict real people, take advice rather than relying on this paragraph.
Advertising and consumer law. Separate again, and the one most likely to cause you trouble in practice. Describing an AI-generated poster as "hand-painted," "original watercolour" or "drawn by me" is a misdescription of the product, actionable under general consumer protection law in every jurisdiction listed on this page, regardless of whether any AI-specific rule applies. The safe formulation is factual and unadorned: state that the artwork was created using AI tools, state what you contributed, and stop.
Jurisdictions differ substantially. Check locally; the following is orientation, not advice.
United States. Payment platforms report on Form 1099-K. The IRS's current guidance describes the threshold as payments for goods or services that exceed 20,000 US dollars in more than 200 transactions. That threshold has moved repeatedly in recent years, so confirm the figure for the tax year you are filing. Critically, the reporting threshold has never determined whether income is taxable. It determines only whether a form is issued. Income from the first dollar is reportable. Net earnings from self-employment above 400 US dollars generally trigger self-employment tax as well as income tax. Sales tax on marketplace sales is generally collected and remitted by the marketplace under state marketplace facilitator laws; on your own storefront it is your responsibility.
United Kingdom. The trading allowance is "a tax exemption of up to £1,000 a year for individuals with trading income." Above 1,000 pounds of gross trading income you must register for Self Assessment, by 5 October following the end of the tax year. Separately, under the digital platform reporting rules, platforms report seller details to HMRC annually by 31 January; your details are not reported if you make fewer than 30 sales of goods in a calendar year and receive less than 2,000 euros (about 1,700 pounds) for them. As HMRC puts it, "platform reporting your details to HMRC does not automatically mean you owe tax". But if you are trading, you owe tax whether or not you are reported.
Canada, Australia and the EU. Each has its own registration thresholds, GST or VAT rules and platform reporting regimes, and EU member states differ from each other on VAT registration and on the treatment of cross-border digital sales. If you are selling from or into any of these, get local advice before your first year-end, not after.
One point applies everywhere: your income is the margin, not the gross. Marketplace payouts arrive net of some fees and gross of others, and supplier charges hit a different account. Reconcile monthly or you will misreport.
Payment risk, chargebacks and account termination
This is the risk category people discover after they have built something.
Refund and chargeback offsets. Amazon's Merch Services Agreement states that if a royalty has been paid and Amazon later issues a refund, credit or receives a chargeback, "we may offset the amount of the Royalty we previously paid you against future Royalties or other amounts that would otherwise be payable to you," or require you to remit it. It also states that "Amazon may, in its sole discretion, choose to liquidate returned merchandise, in which case no Royalties will be payable."
Limitation period. The same agreement provides that "you may not maintain any action or proceeding against us with respect to any report or payment unless you commence that action or suit within 6 months after the date the report or payment was due." Six months is short. If you are not reconciling your royalty reports, the window can close before you notice a discrepancy.
Termination. Amazon's agreement is explicit: "We are entitled to terminate this Agreement and access to your Program account at our discretion with or without advance notice to you," and it may suspend participation "at our discretion with or without notice." The indemnity provisions survive termination.
Indemnity. Under that agreement you "will indemnify, defend and hold us... harmless from and against any loss, claim, liability, damage, action or cause of action (including reasonable attorneys' fees) that arises from any claim relating to any Content." Combined with Midjourney's indemnity running the same direction, the position is that the generator is protected, the marketplace is protected, and you are the party carrying the infringement risk of an image neither of you can fully account for.
Working capital. With Printful or Printify you pay production and shipping at order time and receive marketplace payouts later. On a growing month you are financing someone else's fulfilment. This is manageable at small scale and becomes a real cash-flow problem at the point where it starts working.
Platform concentration. Every element of this business sits inside somebody else's account: the generator subscription, the marketplace listing, the fulfilment partner, the payout method. A single policy change, a single suspension, or a single erroneous IP complaint removes the income with no notice period and, in Amazon's case, no contractual notice requirement at all.
What separates an operation that works from one that doesn't
Given all of the above, the version of this tactic that has any durability looks specific.
Human authorship stops being a legal footnote and becomes the product. The sellers who survive are the ones whose output cannot be reproduced by someone typing the same prompt. That means the model is one step in a process that also includes your own drawing, photography, typography, colour work or composition. This is not a moral position; it is the only route to a design a competitor cannot regenerate in ninety seconds, and it is the only route to anything registrable.
Product and niche selection matter more than design volume. The base cost tables above show why. A poster at 11.50 US dollars base and 42 US dollars retail behaves completely differently from a sweatshirt paying a 0.29 US dollar royalty at 35.99 US dollars. Choose the product line first, then design into it.
Technical execution is a real barrier and a real advantage. Correct resolution for the printable area, correct colour profile, correct bleed and safe margins, files that hold up at 24 by 36 inches rather than looking acceptable at thumbnail size. Redbubble lists file quality among its account classification criteria for a reason. Most bulk AI portfolios fail here, which means competence here is genuinely differentiating.
Order samples. Amazon explicitly recommends it. Colour on a screen and colour on matte paper are different things, and the reviews you get from not checking are permanent.
Trademark screening as a fixed step. Every phrase, every character reference, every brand-adjacent element, searched in the register for the relevant class before upload. This is the single cheapest risk reduction available.
Own something. A brand name you have registered, an email list, a storefront. Everything else in this stack is rented.
A realistic cost and time model
Startup costs are genuinely low, which is the honest part of the pitch.
- Generation tool: 0 to 60 US dollars a month. Midjourney Basic is 10 US dollars a month; Stealth Mode requires Pro at 60 US dollars a month, or 48 US dollars a month paid annually. Adobe's Firefly-bearing plans differ in price and in whether indemnification applies.
- Fulfilment partner: 0 US dollars on Printful Free or Printify Free. Printful Growth is 24.99 US dollars a month; Printify Premium is 39 US dollars monthly or from 24.99 US dollars monthly billed annually. Neither upgrade is worth buying until the discount exceeds the fee.
- Marketplace: 0.20 US dollars per Etsy listing per four months. Nothing on Amazon Merch or Redbubble.
- Samples: one per product line you intend to sell, at base cost plus shipping.
- Optional and later: 65 US dollars per Copyright Office Standard Application where you have genuine human authorship to register; 350 US dollars per class at the USPTO for a word mark.
A realistic first-three-months outlay is therefore roughly 100 to 400 US dollars depending on tool subscriptions and how many samples you order. That is an estimate, not a sourced figure, though every component of it is sourced above.
Time to first revenue is the number nobody can give you honestly, because it depends entirely on demand for the specific niche you pick, and because the platforms do not publish the distribution of outcomes. What can be said from the sourced figures is this: on Amazon Merch's Creator rates you need nine sales of a 19.99 US dollar shirt to clear 20 US dollars in royalties. On Redbubble's Standard tier at the default markup you need five sales of a 20 US dollar base product to clear the 10 US dollar payment threshold. On Etsy at the poster margin modelled above you would clear roughly 16 US dollars per sale before tax, against a listing fee charged whether or not anything sells.
Who should skip this
Stated plainly, because the sections above make the list obvious.
Anyone who needs their designs to stay exclusive. You have no copyright in purely AI-generated output in the United States, you cannot register it, you cannot sue over it, and the platforms will not police lookalikes for you. If exclusivity is load-bearing in your plan, choose a different tactic.
Anyone planning to build a licensing business on top. Licensing requires something to license. You cannot grant a licence over rights you do not hold, and doing so in a written agreement is a misrepresentation to a commercial counterparty.
Anyone who intends to describe the work as hand-made or hand-drawn. Etsy requires the opposite disclosure. Consumer protection law requires the opposite in every jurisdiction listed here. The marketing angle that would make this business easiest is the one that is closed.
Anyone attracted by the ability to upload in bulk. Every platform has already priced bulk uploading in: Etsy through per-listing fees, Redbubble through account tiers that charge high-volume low-effort accounts 50 per cent, Amazon through application gating and upload caps. Volume is the strategy the platforms have specifically engineered against.
Anyone who cannot absorb an indemnity claim. You have indemnified Amazon. You have indemnified Midjourney. Statutory damages for counterfeit marks start at 1,000 US dollars per mark per goods type and reach 2,000,000 US dollars for wilful use. The probability is low for generic decorative art and rises sharply the moment a prompt names a brand, a character or a person.
Anyone who needs predictable income within a defined period. Platform earnings in this category are extremely skewed, the platforms do not publish distributions, and the mean figures that can be computed from public filings. Around 1,868 US dollars of Etsy GMS per active seller per year, before fees and before cost of goods. Are not median figures and should not be treated as an expectation.
Anyone in a jurisdiction whose position they have not checked. The US, UK, EU, China, Korea and Canada have materially different answers to the same question. Sections 9(3) and 12(7) of the UK's CDPA appear to offer more than US law does, but have never been applied to generative AI by any court.
Questions to answer before you spend anything
- What exactly am I contributing to each design, and would the Copyright Office describe it as more than prompting? If the answer is no, accept that the work is unprotectable and plan accordingly rather than assuming otherwise.
- Have I read the royalty or margin table for the specific product I intend to sell, at the specific price I intend to charge, in the specific store? Merch's Comfort Colors sweatshirt at 0.29 US dollars is in the same table as its standard tee at 2.44 US dollars.
- Have I pulled my own region's shipping rates from the fulfilment partner, rather than the ones the site showed me?
- Have I searched every phrase and reference in my design against the relevant trademark register, in the relevant class?
- Do I know which disclosures each platform requires, and have I written them into my listing template rather than relying on remembering?
- If this account were terminated tomorrow with no notice (which both Amazon's and Etsy's terms permit) what would I still have?
