You post a new illustration on a Tuesday. By Friday it is on a t-shirt, a mug and a phone case in a shop you have never heard of, sold by someone you have never met. That is the reality of print-on-demand copying: a thief needs no stock, no printer and no upfront money, only your file. This guide shows you how to find those copies and get them taken down.

To find copies of your design print on demand, upload your original file to Google Lens and TinEye, search cropped, black-and-white and flipped versions, then search inside Redbubble, Etsy and Amazon with your design’s distinctive words. Save dated screenshots of every copy you find, then report each listing through the store’s own intellectual property form.

This article is about your design files copied onto products. It is not about stolen product photos, which is a different problem with different tools. Everything below uses free tools, and every step is one you can repeat for each design in your portfolio.

What Is a Print-on-Demand Copy of a Design?

A print-on-demand copy is your original design file — an illustration, a pattern, a logo or a piece of lettering — printed onto a product and sold by someone who does not own the rights to it. Print-on-demand, usually shortened to POD, means the store prints each item only after a customer orders it, so the seller holds no stock and pays nothing until a sale is made.

That model is what makes copying so easy. A copier downloads your illustration from your portfolio, your shop or social media, uploads it to Redbubble, TeePublic, Society6, Zazzle or Amazon Merch on Demand, picks the products, and collects a share of every sale. Your work does the selling; they take the money. Copies can appear within days of an original going public, and one stolen file can end up on dozens of products across several stores at once.

It helps to know what counts as a copy and what does not. A design in a similar style, with the same subject but drawn from scratch, is not a copy of your file, however annoying it feels. An identical file, a traced version, a recoloured version or a cropped piece of your artwork used on a product is a copy, and that is what this guide helps you find. Under the Berne Convention, which covers most countries including the UK and the US, copyright in an original work exists from the moment you create it, so you do not need to register a design before you can object to a copy.

How to Find Copies of Your Design Print on Demand with Reverse Image Search

Reverse image search is the fastest way to find copies of your design print on demand, because it searches by what the image looks like rather than by words a seller chose. Work through the steps below with your original file, not a screenshot of it: screenshots add compression and borders that weaken the match. If you need a refresher on the basics, our step-by-step reverse image search guide covers each tool in detail.

Start with Google Lens. Open lens.google.com, upload your original export, and look first at the exact matches and the pages that contain the image. Then scroll through the visually similar results, because that is where edited copies hide. Lens has the widest coverage of any free tool, so it is the best place to begin.
Repeat the search on TinEye. TinEye uses a different index and often finds copies Google misses. Its help pages explain that you can sort results by oldest first, which shows the earliest copy TinEye has seen, and by most changed, which surfaces edited versions. Oldest first is useful evidence: if your own post is the earliest result, it supports your claim that you made the design first.
Try Bing Visual Search as a third index. Bing sometimes finds listings the other two miss, and it costs nothing to check. Run the same original file and compare the results with the first two searches.
Search edited versions of your file. Copiers rarely upload your file untouched. Make four extra versions and search each one: the main motif cropped on its own, a black-and-white version, a horizontally flipped version, and a small thumbnail-sized version. A copier who changed the colours will still match a greyscale search more often than a colour one, and mirroring is a common way to disguise a copy.
Search your mockup images too. Copiers often lift your presentation images — the t-shirt mockup or the framed-print photo from your shop — rather than the design file itself, so run those through Lens and TinEye as well.
Keep a log. For every copy you find, note the date, the tool that found it, the listing URL and the seller’s name, and save a screenshot with the URL and date visible. Pages disappear quickly once a seller realises they have been found, so capture the evidence before you contact anyone.

One honest warning: reverse image search is not perfect. A heavily traced design with new colours may not match the original directly, and some marketplace listings are never indexed by any image search engine. That is why the next two sections matter as much as this one.

Which Tools Find Print-on-Demand Copies Best?

No single tool finds every copy, so use them in combination. The table below compares the free options that matter for print-on-demand copies.

Tool	Best for	Limits
Google Lens	Widest coverage; similar images and pages using the file	Leans towards similar images, so exact copies can hide among lookalikes
TinEye	Exact and edited copies; oldest-first sorting shows first appearance	Smaller index than Google
Bing Visual Search	A second large index that sometimes finds what Google misses	Fewer filtering options
Pinterest visual search	Copies pinned and shared as inspiration; common for illustrations	Only covers Pinterest
In-store search	Listings that image search never indexes	One store at a time; needs the right keywords

For most designers, the practical routine is Lens first, TinEye second for proof of first appearance, Bing third for anything the others missed, and then the in-store searches described below. Pinterest visual search is worth adding if your work is illustration or pattern-led, because copied designs are often pinned as “inspiration” long before they appear on a product. Run the full routine when a design goes public, and repeat it every few months for the designs that earn money.

How Do I Search Inside Redbubble, Etsy and Other Print-on-Demand Stores?

Many copied listings never appear in image search at all. Marketplace pages often sit behind search results that image engines do not index, and some stores limit crawling. So search inside each store directly, using the words that make your design distinctive.

Start with a text search on the store itself. On Redbubble, TeePublic, Society6 and Zazzle, type the most distinctive words from your design into the search bar: a slogan, a character’s name, an unusual phrase or a combination of subject and style, such as “fox autumn leaves illustration”. On Etsy, use the same words in the main search bar and filter by the product type, for example t-shirt or mug. On Amazon, search the phrase and look in the clothing and home sections where Merch on Demand products appear.

Then use Google’s site search to go deeper. A query such as site:redbubble.com “fox autumn leaves” searches only Redbubble for that exact phrase, and you can swap in each store’s domain in turn: site:teepublic.com, site:society6.com, site:zazzle.com, site:etsy.com. Put your design’s distinctive words in quotation marks so Google matches the exact phrase rather than the separate words, and try two or three different word combinations, because sellers often rename a design to dodge exactly this kind of search.

When you find one copy, check the seller. A copier who stole your design has usually stolen others too, so open the shop or profile and browse everything they sell. One report that lists several of your designs is more efficient than a separate report for each, and a shop full of other artists’ work strengthens your case with the platform. Also reverse-search the listing’s own mockup image: if the seller reused your presentation photo, that image can lead you to further copies on other stores.

Worked Example: Finding a Stolen Fox Illustration on a T-Shirt Listing

The example below is a worked-through scenario, not a real case, showing how the steps above fit together. The tools behave as described, but your own results will vary: some searches will find nothing, and some copies will only turn up inside a store.

Maya is a freelance illustrator. In March 2026 she draws a fox curled among autumn leaves, sells prints of it from her own website, and posts it on Instagram. Two months later a buyer emails her: “I saw your fox on a t-shirt — are you selling shirts now?” She is not, so she starts checking.

Google Lens. Maya uploads the original PNG to lens.google.com. The exact matches show her own Instagram post and her website. Among the visually similar results, one shows a t-shirt with her fox on it, listed on Redbubble.
TinEye. She runs the same file through TinEye and sorts by oldest first. Her March Instagram post is the earliest result, and the Redbubble listing appears later, which supports her claim that she created the design first.
Edited versions. She crops the fox on its own, makes a black-and-white version, and searches both. The cropped search finds the same design on a mug on Etsy and on a phone case on TeePublic — copies the first search had missed.
In-store search. She searches Redbubble for “fox autumn leaves illustration” and finds the listing directly, then searches Etsy and TeePublic with the same words and finds the other two listings.
Evidence. Before contacting anyone, she screenshots each listing with the URL and date visible, saves the pages, and notes the seller names. On Redbubble she opens the seller’s shop and finds more than forty listings, several of which look like other artists’ work.
Report. She files a Notice and Takedown Report with Redbubble for the t-shirt listing, then reports the Etsy mug through Etsy’s reporting portal and the TeePublic case through its own form, attaching the same evidence to each.

The whole check takes Maya under an hour, and it finds three copies that a single search would have missed. That is the point of the routine: each tool and each store search catches something the others do not.

What Should I Do When I Find a Copy of My Design for Sale?

Finding the copy is only half the job. What you do next decides whether it comes down quickly or stays up for months, so work through these steps in order and keep copies of everything you send.

Collect the evidence first. Screenshot each listing with the URL and date visible, save a copy of the page, and note the seller name, the listing URL, the products it appears on and the price. Do this before you contact the seller or the platform, because listings disappear once the seller realises they have been found.
Gather proof that you made it first. Collect your dated source files and early sketches, the earliest date the design appeared on a site you control, any client approval email, and the TinEye oldest-first result showing your version as the earliest copy. Together these make a much stronger report than a complaint on its own.
Report it to the platform. Every large print-on-demand store has its own intellectual property report form, and that form is the fastest route to removal. According to Redbubble’s IP/Publicity Rights Policy, a Notice and Takedown Report must include your signature, a description of the work, the listing URL, your contact details, a good-faith statement and a statement made under penalty of perjury, and reports can also be sent to dmca@redbubble.com. According to Etsy’s Intellectual Property Policy, you can report a listing through the Etsy Reporting Portal, Etsy removes material when it receives a report that complies with its policy, and sellers who repeatedly infringe can have their selling privileges terminated.
If the platform does not act, escalate in writing. A formal letter asking for removal and a licence fee for the sales already made carries far more weight than a second report form. Our guide to sending a copyright demand letter explains what to include and how to work out a fair fee, and the same approach works for print-on-demand copies.
For serious cases, get professional help. If the copy is being used as a competing brand, or real money is at stake, speak to an intellectual property lawyer. Our guide to documenting image evidence explains how lawyers use reverse image search results and dated files to build a case, which helps you prepare the material they will ask for.
Check the wider picture. A design stolen for a t-shirt is often stolen elsewhere too. Run the same checks on your other popular designs, and read our guide to finding and removing stolen creator content for the full removal routine that covers every kind of stolen work, not just print-on-demand products.

This article is general information, not legal advice. If a dispute involves significant money or a counter-notice, speak to a qualified intellectual property lawyer before you act.

How Can I Stop My Designs Being Copied Again?

No method stops copying entirely, and anyone who promises otherwise is selling something. What you can do is make copying harder, make proof easier, and catch copies sooner, so each one costs the copier more than it earns them.

Publish on a site you control first. Put new work on your own portfolio or shop before or alongside social media and marketplaces, so there is a dated original under your name.
Keep dated source files and early sketches. They are the strongest evidence that the work is yours, and they cost nothing to keep.
Show lower-resolution previews. Share mockups and watermarked previews online and keep the full-resolution files for clients and your own shop.
Add your name and copyright details to file metadata when you export. It takes seconds, and it travels with the file.
Register the trademark for any logo a business cannot afford to lose. Copyright protects the artwork; a registered trademark protects its use as a brand, and it makes every enforcement step faster.
Run the checks on a schedule. Check each new design when it goes public, then repeat the routine every three months for the designs that earn money, and keep a note of what you found and when.
Watch for other kinds of misuse too. A design that is copied onto products may also have been scraped for other purposes, so it is worth learning how to check if your photos were used to train AI as part of the same routine.

Think of it as maintenance, not a one-off fix. A designer who checks quarterly and reports quickly loses far fewer sales to copies than one who discovers a stolen design a year after it first appeared. The tools are free, the routine takes under an hour per design, and the habit is what protects your income.

FAQs

Can reverse image search find my design on a t-shirt?

Yes, often. Upload your original file to Google Lens and TinEye, then search cropped, black-and-white and flipped versions, because sellers often edit a design before uploading it. Some listings never appear in image search, so also search inside each store with your design’s distinctive words.

What should I do first when I find my design on Redbubble?

Save the evidence before anything else: screenshots showing the listing URL and date, the seller’s name and the listing link. Then gather proof you created it first, such as dated source files, and file a Notice and Takedown Report through Redbubble’s own form.

Do I need to register my design before I can report a copy?

No. Under the Berne Convention, copyright exists from the moment you create an original work in most countries, including the UK and the US, so you can report a copy without registering anything. Registration makes proof easier, but it is not a requirement for a takedown report.

How often should I check for copies of my designs?

Check each new design when it goes public, then repeat the routine every three months for designs that earn money. A quarterly check takes under an hour per design and catches copies while they are still new, before they have made many sales.
