Full color refers to the 4 primary colors used in the CMYK printing format. Cyan, Magenta, Yellow, and Key (black) are used to replicate nearly any color from digital to physical. If you send us an RGB file, there is a chance that a color shift may occur and you may not be satisfied with your job. You should always start and finish your designs in CMYK color mode.

White - The print will show up on a white background (non transparent)

Clear - The print will show up on a clear background (transparent)
