The general rules for submitting artwork are as follows:
We prefer that the art is submitted in an Adobe Illustrator file (.ai, .pdf, .eps format). Or if your art was created in Canva, we would need the direct link to your design. If your art was not created in either of those formats, still send us your art and we will try to work with it.
The thinnest lines cannot be less than 0.25 point
There can be no gradients, shadows, or colors tints
Maximum of 6-colors:
No greater than six colors: It is important to understand the actual process of screen printing in order to understand why multiple colors’ cause problems. Each color requires a separate screen to be created that corresponds to that color. Then each screen must be perfectly registered over the other so that no overprinting of color occurs. The more colors you print, the more likely you are to have a registration problem.
