AI Images for Etsy and Print on Demand: A Seller's Checklist

A seller does not need another essay on whether AI art is good. A seller needs to know what to check before a listing goes live. This is that list, in the order to run it for a small shop selling posters, stickers, mug art or digital downloads: six checks, a short order of work, and a paragraph on what a generator will not do for you.

Check 1: read the marketplace's own AI rules

Every marketplace and every print-on-demand partner sets its own rules for AI-made work. Some ask you to disclose it, some limit what may be listed as handmade, some restrict whole categories. They change, so we do not quote any here and you should not trust a blog post, this one included, for the current wording. Open the seller policy where you list, find the AI section, and read the print partner's as well. Do it before you generate anything: if your shop does not fit the rules, nothing below matters.

Check 2: know what our terms give you and what they do not

The terms are short on this. We claim no ownership of what you generate and place no restriction on commercial use: sell it, put it on a product, use it in client work. We take no share and require no credit.

Two things are not included. There is no exclusivity: another user writing a similar prompt may receive a materially similar result, so a look-alike from another seller is possible. And there is no copyright warranty: we do not promise you own copyright in the output or that it is protectable at all, because in several countries a work made purely by a machine may not qualify. Both are laid out in the commercial use post and who owns AI images. For a shop the practical reading is simple: you can sell the poster, but you may not be able to stop a copy, so put your effort where copying is hard, in your selection, your series, the text and layout you add yourself, and the voice of the shop.

Check 3: choose the shape for the product, before you generate

Decide the product first, then the frame. The studio offers a list of aspect ratios, and the price does not change with the shape, as the aspect ratio guide explains. Portrait ratios such as 2:3, 3:4 and 4:5 are the usual poster and print shapes. Use 1:1 for square stickers and coasters, and a wide frame such as 2:1 or 3:1 for a mug wrap. Your print partner's template is the authority, so read its proportions first. If the exact shape is not on our list, generate a little wider than you need and crop.

Pick the format with the same care: PNG is lossless and larger, JPEG is smaller. For anything you will print, take PNG.

Check 4: do the pixel arithmetic before you order stock

Quality has two steps in the studio, labelled 1.5K and 2K. Those are size classes, not a pixel count we publish for each shape, so do not trust the label: download the file, open its properties and read the pixel size. Then divide the pixels by the print size in inches. The result is pixels per inch, and every print partner states what it wants. Many ask for around 300, but check yours. A file that is too small for a poster prints soft.

The studio has no upscaler, so no setting rescues a small file afterwards. Your options are to print smaller, to render at the higher quality step, or to run the file through a separate upscaling tool and then look at the result at full size. The lowest-cost model in the picker renders smaller still, and only as JPEG, so use it to sketch ideas and never to produce a print file. See the quality and format guide for the trade-off.

Check 5: no real faces, no famous characters

Our terms rule out using output in a way that infringes a trademark, a person's likeness or another work, and a photo of a person may only be uploaded with that person's permission and the rights to the picture. A cartoon mouse, a wizard school or a celebrity on a mug belongs to someone else, and a prompt that reproduces a recognisable character is where a takedown notice comes from. Make your own characters instead.

Reference images are the tool for that: attach your own drawing and the generator can carry its look across a whole sticker sheet. Each reference adds a surcharge and the count is capped, so see the product page, and the budget model does not take them. The reference images post shows how.

Check 6: download the same day

Generated files are stored for a limited time and then deleted; the studio shows the number of days beside your history. Your permission to use a file survives its deletion, but the file does not. Download the final in the format you need, and keep a note of the prompt and settings next to it. There is no seed lock, so the same prompt again gives a different picture, not the same one back. A listing that sells for months needs a file you hold.

The order of work

1. Sketch at the standard step; drafting first costs less than polishing the wrong idea.
2. Choose the frame from the product template, not from the picture.
3. Render the keeper at the higher step, as PNG.
4. Open the file, read the pixels and compare them with the print size.
5. Download it, save the prompt note, then add any lettering and the layout in your own design tool.

What the generator cannot do for you

It cannot promise exclusivity or copyright, and it cannot tell you whether a marketplace will accept the listing. It does not print, ship or list anything. It gives you a plain PNG or JPEG, with no bleed, no print colour profile and no transparent-background setting, so cutting a sticker shape out is a job for your editor or your print partner. Lettering inside a picture often comes out misspelled, so set text yourself. Renders can also come out wrong, and the terms promise no particular accuracy, so look at every piece at full size before it goes on sale. A failed generation is refunded; a finished picture you do not like is not. And it will not give you a real person's face or a franchise character you have no rights to. When the checks pass, start in Fellowi Images.
