What's the best file format to supply?

We recommend creating your design in Photoshop and saving your file as a transparent png. A good rule of thumb is make it big, setup at print quality (300dpi) around the size of the print area. This varies from product to product but 12" wide x 15" tall will work best for shirts.
You can also create files in Illustrator or other vector based programs - save your file as an eps 300dpi or higher - with a transparent background.

Why transparent? using transparency will give you a much better idea of how it will print on the shirt color you choose. If you use a jpeg then it will still have colored pixels in the background.
Files downloaded from the internet are usually low quality (72 dpi) and will print with pixelation and atrifacts.

Don't worry you can proof your design before ordering and our designers will always review your file and if we see any obvious issues they will alert you before going to print. Ultimately you are responsible for your file quality but we want you to be happy with your custom shirt so we'll help you as much as possible.

The higher quality file in = the best quality apparel out.
