Color matching is off. Colors are not printing the same as they appear on screen or do not match PMS colors.
Tweak the Color of the Source. Exact color matching of the printed discs to the screen may never be possible since there are factors that are out of the driver's control. The surface of the disc reacts with the ink in the cartridge to produce the color. For this reason, it may be necessary to tweak the color of the source image to print the way you want on disc. In this case it is possible that the color displayed on screen may not be the color that you want printed, but when the disc is printed it looks the way it is supposed to look.
Note: There are many other printing problems that can look like color matching issues. The solutions above are only applicable if the disc looks vibrant, bright and fully saturated but the colors are off. For all other issues search the knowledge base for "Print Quality" under your specific product. Many of these problems can be solved by manually cleaning the ink cartridges.
