What is the color model for printing, CMYK or RGB?

It’s important to note that they may look different on a real product than what you see on your computer monitor when choosing the colors for your artwork. To get the best outcome for your prints, use RGB for your files with printed apparel, with All-over prints, CMYK is the color profile our printers use to best represent the color of the product compared to the design. Always check the profile and color-correct with our support if necessary.
