Why does my shirt design print with a white box around it?

Because the file has a background. A JPG, or a PNG saved on white, prints everything in the file, box included. A transparent PNG holds only the design.

  1. Check the file. Open it over a dark background. If you see a rectangle around the art, the box is in the file.
  2. Remove the box. Upload the file here: the box and its soft shadow are removed and the art is not redrawn.
  3. Look at it on dark and on light. The free preview shows the design on a black and on a white shirt color.

Why a JPG always has a box

The JPG format cannot store transparency. Every pixel has a color, so the area around the art is saved as white.

A PNG can have one too

A PNG saved from a flattened image has an opaque white background. The file type alone does not tell you.
