For detailed instructions, refer to "Separation Management" in the Rainbow™ Color Proofing System User's Guide.

For users who wish to proof/print specific colors or send and proof separated files with more than CMYK plates, Rainbow™ software includes three color libraries: PANTONE™, 3M Matchprint™, and Custom Colors. Users also can create their own customized libraries. Colors included in these custom libraries are output according to their L*a*b* color space measurements. Up to 8 color separations per page can be sent and proofed.

The Separation Management feature of the Rainbow™ controller software is used for holding the supplied color libraries (such as PANTONE™), creating and maintaining the customized color libraries, and setting separation printing priority.

From the Separation Management Dialog box, the user can:

• Create a new color library that then becomes selectable in the Color Library pulldown menu.
  
• Add specific, custom colors to unprotected color libraries-color libraries the user creates-using their L*a*b* color space measurements or the Color Picker dialog box.
  
• Select the separation printing priority (if using a custom ribbon). The separation printing priority determines the order in which separations will be printed on the proof.

  - Example:
  Process colors, CMYK, are preassigned a priority of 0. Therefore, to have the Rainbow™ proofer lay down a custom color before CMYK, the user must specify a negative priority number for that color, such as -1.

  - The software will display a message telling the user when to put in the custom ribbon and when to put back the CMYK ribbon.

Color Libraries Feature

Allows you to:

• View colors from supplied color libraries
  
• Create customized color libraries
  
• Add, delete, duplicate, or edit colors from unprotected color libraries

Printing Custom Colors

Be sure to:

• Send as separated files from the page layout or graphic application. If custom colors are sent as a composite proof, the colors are run through the selected CMYK color target color space of the Rainbow™ software; when sent as separate plates, the colors are run through their own color space.
