You find the spot color definitions in the Settings Editor. To select the most appropriate color, a
patch chart print is available. Use this print as a spot color representation on the media you use.
New or changed spot colors are stored in a custom spot color library. You can import or export
spot color libraries.
Color mapping
Use color mapping to convert RGB and CMYK color input values to specific output colors, for
example, your corporate color. Color mappings are useful to map colors in the input file to a fixed
spot color of a spot color library. With color mappings you ensure that specific input colors
always result in the same output color. Assign color mappings to one or more color presets to
include them in the job preparation workflow.
Leave out separations
You can use color mapping to indicate layers in the document that you want to leave out whilst
printing. You can exclude layers for printing when you map the colors of these layers to a spot
color with the value "None". You can use leave out separations for the following document
areas:
• White separations
• Cutting marks
• Spot layers, that indicate a foil to be applied after the print process
• Spot layers, that indicate a gold print
