Defining Colors
When defining colors, use a printed ink guide before entering values in the color palette. RGB color monitors do not accurately represent ink on paper. This is because of the different color gamuts associated with printing vs. monitor screen representation.

Process vs. Spot Colors
Many desktop programs allow you to specify colors in three ways: You can specify a spot color by product name such as Pantone®, a process color by setting CMYK percentages and process color tints based on pre-determined systems such as TRUMATCH®. Whenever choosing colors, always work from printed swatchbooks, not what you see on the screen. Make sure you specify your color as a spot in Quark or PageMaker and make non-spot colors process.

Color Names
If you are using duotones or FreeHand or Illustrator eps files with a spot color make sure each program uses the same name for the spot color coating indication. Ex: Pantone 289 CVC will print on a different plate than Pantone 289 CV. Spot color names should be the same in all programs. (Quark favors CV so it is good practice to change all your spot color names to CV if you will print from Quark)
