Although we can screenprint mostly any kind of image, the simpler the graphic, the better it tends to be for screen-printing.
When we say “simpler”, that could be defined by the following:
- areas filled with solid color (as opposed to complex gradients, textures, or transparencies)
- limited color count (anywhere from 1-10 colors)
Aside from that, the world is really your oyster. If you are unsure whether or not your artwork is well-suited for screenprinting, just send it to firstname.lastname@example.org for a review.
