The printing color range is more limited than what you will see on your computer screen. Vivid print colors won’t typically come through, so be careful about making this a central part of your design or idea.
We accept files with various color spaces, but our system does all operations in RGB. If you upload a CMYK file, be aware that our system will convert it to RGB and the colors might shift significantly.
When someone creates a design, or uploads a piece of artwork with various print colors, that picture is stored in computer software as RGB. However, that RGB format must be translated into CMYK before the design in question can be printed. This is because, instead of a screen projecting various print colors, the tints we perceive on a garment are only the reflected wavelengths of visible light.
