License guide for PNG t-shirt designs
How to avoid copyright issues and ensure commercial quality in your prints.
IP infringement is the biggest risk for online t-shirt stores. Platforms like Shopify, Etsy, and Mercado Libre permanently ban accounts for copyright claims.
Understanding usage licenses
Personal vs Commercial use
Most free web resources are 'Personal Use Only'. You cannot profit from them on physical products.
Look for platforms granting clear commercial (POD) licenses. This authorizes printing on garments, but rarely allows reselling the digital file.
Technical requirements of a good PNG
Not every PNG is useful
PNG format supports lossless compression and alpha channels. However, a 72 DPI web image will print pixelated at 12 inches.
Demand 300 DPI files, in RGB or CMYK (as per your RIP needs), with absolutely clean transparency channels (no white halos).
Avoiding algorithmic tracking
Modifying resources
Even with legal resources, it is good practice to add your touch: change colors, add typography, or combine elements.
This creates unique designs and avoids false positives from copyright bots on major e-commerce platforms.

Frequently asked questions
What resolution should files have for DTF and sublimation?
We recommend using PNG format with a transparent background at 300 DPI in actual print size (e.g., 11x14 inches for A3) to ensure maximum sharpness.
Do I need my own plotter to start?
No. You can start by buying printed DTF gang sheets from a local supplier and only invest in a good heat press. This reduces your initial risk.
