Short answer: RGB and CMYK are two different color models that you need to be aware of when sending us full-color artwork.
RGB and CMYK are two different color models. RGB uses the colors of Red, Blue and Green and is primarily used for electronic display such as computer monitors. CMYK uses the colors of Cyan, Magenta, Yellow, and Black. This color model is used primarily for real-life printing. All of our full-color printing is CMYK printed.
RGB colors may appear more saturated on screen and colors may look altered when converting from RGB to CMYK. Unfortunately some bright RGB colors that are viewed on a back-lit monitor cannot be replicated through a CMYK printing process.
