How to avoid copyright infringement with t-shirts

Copyright and how it protects your merch

Under US copyright law (17 U.S.C. § 102), copyright is the legal mechanism that lets creators control how their work is used, copied, and distributed. The moment a t-shirt design is finished and saved in any fixed form, that protection kicks in automatically, independently of registration.

For t-shirt sellers, artwork, illustrations, graphics, and specific design elements can all be protected. The Supreme Court confirmed inStar Athletica, LLC v. Varsity Brands, Inc. (2017) that design features on apparel are copyrightable when they can be perceived as a work of art separate from the garment itself.

What copyright does not protect:

• Ideas and concepts
• Short slogans
• Titles and names
• Colors or lettering styles on their own. 

Protection lasts for the creator’s lifetime plus 70 years, after which the work enters the public domain.

Trademark vs copyright: Key differences for apparel sellers

• Copyright protects creative works – artwork, illustrations, photography, and original graphic designs. It happens automatically at creation.
• A trademark protects brand identifiers – names, logos, and slogans that distinguish one company’s goods from another’s. Trademarks must be registered (or established through commercial use) and are renewable indefinitely, unlike copyright.

For t-shirt sellers, trademark infringement is the more common legal pitfall. Printing a brand logo, sports team name, or celebrity-associated slogan for commercial use almost always violates trademark protections – even if you drew the logo yourself. The test is whether a customer might be confused about whether the trademark owner endorsed the shirt.

Common t-shirt design pitfalls: What counts as infringement?

Copyright infringement happens when a copyrighted work is reproduced, distributed, or made into a derivative work without the permission of the copyright owner. 

For apparel sellers, the most common violations include:

• Using images downloaded from Google.
• Reproducing characters from movies or games without a licensing agreement.
• Printing song lyrics or book quotes.
• Using brand logos without authorization.
• Taking another designer’s copyrighted content and making minor changes.

Understanding right of publicity vs copyright

Putting a real person’s face on a t-shirt raises a legal issue separate from copyright: the right of publicity. This is the right of individuals – particularly public figures and celebrities – to control how their name, image, and likeness are used for commercial purposes.

In the US, publicity rights are governed at the state level, meaning protections differ significantly depending on where you operate or where the subject lives. 

Most states recognize some form of this right for public figures, and several extend it to private individuals too, covering how their name, image, and likeness can be used in advertising, on merchandise, and in promotional contexts. Many states extend these protections to deceased individuals for 10 to 100 years after death.

The risks of using celebrity likenesses in your merch

The key legal distinction is commercial use. Creating a single painting of a celebrity occupies a different territory from mass-producing t-shirts bearing their face and selling thousands of units.

In Comedy III Productions, Inc. v. Gary Saderup, Inc. (2001), the California Supreme Court ruled that charcoal portrayals of the Three Stooges on t-shirts violated the right of publicity rather than constituting protected art because the artist’s skill was subordinated to the goal of commercially exploiting the celebrities’ fame.

Even if you draw or illustrate a likeness yourself, selling it on merchandise exposes you to publicity rights claims.

When can you legally use a face in your design?

There are narrow circumstances where using a real person’s likeness on a shirt is acceptable.

• You have explicit written permission from the person or their estate.
• The person is a political figure, and the design constitutes political commentary, which receives strong First Amendment protection.
• The work is genuinely transformative parody – meaning it clearly comments on or satirizes the person rather than simply exploiting their image for profit.

If none of those apply, don’t use real people’s faces on shirts you plan to sell.

How to create 100% original artwork for your brand

The most reliable way to avoid copyright infringement when creating custom t-shirts is to start with original art from scratch. 

Practical approaches for building a clothing line with original t-shirt designs include:

• Sketching your own illustrations and digitizing them.
• Building unique designs from basic shapes in vector design software like Adobe Illustrator or Affinity Designer.
• Commissioning professional graphic designers through platforms like Upwork or Fiverrwith a contract specifying that you receive full ownership and commercial rights to the final creative work.

Using royalty-free assets and commercial use licenses

“Royalty-free” doesn’t mean free. It means you pay once (or not at all, for truly free assets) and don’t owe ongoing royalties per use. It does not mean the asset is in the public domain or available without restrictions.

Before using any asset in a t-shirt design you plan to sell, confirm two things:

• Commercial use is permitted (many free resources only allow personal use), 
• The license covers Print on Demand. 

Some platforms, including Adobe Stock, require an extended license for items manufactured for resale – a standard license does not cover unlimited print runs of custom t-shirts. When in doubt, review the licensing agreement carefully and save a copy – it’s your primary defense if a copyright claim arises.

Royalty-free images from Creative Commons sources also vary in terms:

• Some prohibit commercial use.
• Some require attribution.
• Some prohibit derivative works. 

Check whether design elements such as textures, patterns, or icons have their own license terms before incorporating them into your shirt designs.

Navigating public domain images for vintage designs

Public domain works are free to use commercially. A work generally enters the public domain when:

• Its copyright expires.
• When the creator explicitly dedicates it to public use.
• When it was produced by a US federal government agency. 

Reliable sources for high-quality images include Wikimedia Commons, the US Library of Congress, and NASA’s image library – all useful starting points when creating custom t-shirts with a vintage or historical aesthetic.

One important limitation: Just because the underlying work is in the public domain doesn’t mean every reproduction of it is free. 

• A museum’s high-resolution photograph of a public domain painting may carry its own copyright. Verify the specific file you’re using, not just the work it depicts. 
• National symbols and government insignia also sit in a gray area – many are public domain, but some carry trademark protections or restrictions on commercial use.

The legal gray areas of AI training and output ownership

AI-generated art has introduced new complexity into print-on-demand/copyright law, and t-shirt copyright rules around AI outputs differ across other countries, too. 

The US Copyright Office affirms that AI outputs can be protected by copyright only where a human author has determined sufficient expressive elements – including situations where a human-authored work is perceptible in the output or where a human makes creative arrangements or modifications, but not the mere provision of prompts alone.

If you type a prompt and download the result without meaningful creative modification, that image likely can’t be copyrighted by you. 

If a competitor or other creators copy your AI-generated design, you may have limited legal recourseunless you made substantial human creative contributions to the final output.

Why prompts referencing specific artists put you at risk

Because AI models are trained on vast amounts of existing visual content – including copyrighted artwork – their outputs can land uncomfortably close to protected material without any deliberate intent.

Use AI as an assistant rather than a replacement. Let it inspire concepts, then build original work from there. Avoid prompting recognizable IP – characters, logos, specific artist names, and famous styles all increase copyright infringement risk. 

If the output looks too close to existing copyrighted material, start over and redesign.

How to check if an AI-generated design is safe to use

Generating an image is only half the process – clearing it before you publish is the other half. 

Before listing any AI-generated t-shirt design for sale, run it through a reverse image search to check whether the output substantially resembles existing original works, brand logos, or other copyrighted material. 

This is the same clearance step professional graphic designers apply to any new artwork, and it’s just as relevant when the image came from a prompt.

Here’s a practical workflow:

1. Google Images – Drag and drop your AI output directly into the search bar. Google will surface visually similar images from across the web, flagging potential matches with existing artwork or protected designs.
2. TinEye – A dedicated reverse image search engine that tracks where images appear online and can identify near-identical reproductions, useful for spotting if an AI tool has essentially reproduced an existing creative work.
3. Bing Visual Search – Runs a separate index to Google and can surface matches that the others miss, particularly useful for product imagery and commercial design.

If any search returns results that look substantially similar to your output – especially artwork by living artists, brand logos, or iconic characters – treat it as a red flag. Modify the design significantly, prompt with different parameters, or set it aside entirely. 

Similarity doesn’t have to be exact to create infringement risk. Courts apply a “substantially similar” standard, which means a design that clearly evokes another creative work can still be a legal problem even without being a direct copy.

Using the Printify AI Image Generator for safe, original concepts

Printify’s built-in AI Image Generator helps you create original t-shirt designs directly within your workflow, without navigating unclear third-party licensing. 

Using it alongside Printify’s Product Creator gives you a direct path from concept to published listing. Always review AI-generated outputs before publishing, applying the same scrutiny you’d give any other design asset.

Stop internet infringement: Monitoring for stolen designs

Protecting original artwork is an ongoing responsibility. Useful monitoring tactics include the already mentioned Google reverse image search (upload your design at images.google.com), the TinEye reverse image engine, Google Alerts for your brand name, and periodic searches of major marketplaces for your distinctive phrases.

Consider registering valuable designs with the US Copyright Office at copyright.gov. 

At $45–$65 per work, registration is relatively low-cost and pays off significantly if someone steals your designs. It’s what makes statutory damages of up to $150,000 per willfully infringed work available to you, along with attorney’s fee recovery.

How to handle a DMCA takedown notice correctly

A Digital Millennium Copyright Act (DMCA) takedown notice is a formal claim that content you’ve published infringes copyright. 

If you receive one:

1. Read it carefully and identify exactly what content is being claimed.
2. Verify the claim. Is the content something you created, licensed, or have rights to use?
3. If valid, remove the content promptly. Delaying compounds legal exposure.
4. If incorrect, file a counter-notice with your contact information, identification of the removed content, and a statement of good faith belief that the removal was an error.
5. Document everything – correspondence, timestamps, and evidence of your original creation or license.

After receiving a valid counternotice, the service provider must wait 10–14businessdays before restoring the content, unless the claimant files a lawsuit within that window. Only dispute claims you have genuine grounds to challenge.

Filing your own takedowns to protect your brand’s unique art

If you discover someone else using your original artwork, the DMCA process works in your favor, too. A takedown notice requires three main pieces of information: the infringing URL you want removed, the source URL where the content originated, and a description of how you own the content and how it was used without authorization.

Most major platforms have dedicated DMCA submission forms. For persistent or commercial-scale infringement, consult a trademark attorney who can send formal demand letters and, if warranted, initiate litigation.

Staying compliant with fan art and pop-culture references

Creating fan art as a tribute can feel harmless, but selling it on merchandise almost always constitutes copyright and trademark infringement. Movies, TV shows, games, comics, and anime are frequent sources of copyright issues – Disney, Marvel, Star Wars, Harry Potter, and major sports leagues are aggressively protected by their rights holders. Even if you draw a character yourself, if it’s recognizable as the rights holder’s property, you’re at legal risk.

If you want to engage creatively with a franchise, focus on unique designs that reference themes or aesthetics, rather than reproducing specific protected characters or logos.

Why “no intent to sell” won’t protect you from a lawsuit

A persistent myth is that personal, non-commercial, or small-scale use of copyrighted material is automatically protected. It isn’t. 

Courts evaluate fair use on four factors: 

1. The purpose and character of the use
2. The nature of the copyrighted work
3. The amount used
4. The effect on the market for the original

Commercial use – including selling t-shirts with song lyrics, logos, or characters – weighs heavily against a fair use finding. News reporting, education, and commentary receive more protection – selling merch does not.

“It’s a parody” also isn’t a magic shield. Parody must clearly comment on or critique the original work, not simply use it as decoration or a shortcut to building a clothing line. When in doubt, don’t use the material.

Checking your slogans in the official trademark database

Short slogans aren’t protected by copyright but can be registered trademarks. 

Before building a brand around a phrase, search the USPTO’s trademark search feature, filter by “live” trademarks, and check International Class 25, which covers clothing, footwear, and headgear. 

A trademark attorney can conduct a professional clearance search before you invest in branding and production costs.
