Products on IdoPrint.com are printed using the CMYK process. Files submitted must be in CMYK color mode. If your files are submitted using any other color model, such as RGB or Pantone, they will be converted to CMYK. Converting from one color model to another may cause un-expected color shifts.

 

Monitors do not always accurately represent how your colors will print on paper. Your computer’s monitor uses RGB to represent color. RGB has a much wider color gamut than CMYK. Therefore, there are colors your monitor can render that cannot be printed using CMYK. Pantone colors may also not convert well to CMYK. Pantone (PMS) inks are premixed inks that use a wide variety of pigments outside the CMYK gamut. Some PMS colors convert fine when printed in CMYK. Others like metallic gold, metallic silver, reflex blue, or fluorescent have no corresponding CMYK equivalent.
