CMYK in FrameMaker (continued)

Defining your own libraries
=====================================
Finally, note that you can define your own libraries. From the online
"Customizing FrameMaker" manual:

"ColorLib [in maker.ini] specifies the folder that contains color
library
files. These files are read in at startup and appear in the Color
Libraries
pop-up menu in the Color Definitions dialog box. You can add any
library
file formatted in the ASCII Color Format (.acf), version 2.1 or
earlier, or
in the Binary Color Format (.bcf), version 2.0. You can't use a
FrameMaker
product to save a .bcf library file."

A web search might reveal details of these file formats, but if not,
the
ASCII one is pretty obvious. Here's a file I put together:

ACF 1.0
My Color Library
LibraryVersion: 1.0
Copyright: © 2005 Mike Hardy. All rights reserved.
AboutMessage: Colors for my company
Names: Partial
Rows: 4
Columns: 4
Entries: 2
Prefix:
Suffix:
Type: Process
Models: CMYK RGB
PreferredModel: RGB
Data:
0 0.25 0.5 0.25
65535 32768 0
Burnt Orange
0.5 0.25 0 0.25
0 32768 65535
French Blue

You can then control exactly what RGB values FrameMaker uses for
display and
printing:

- determine the RGB values that you want to use for display, and note
down
the RGB values

- determine the RGB values that you want to use for printing, perhaps
by
trial and error in another application

- set the FrameMaker Color Definitions dialog to your RGB values for
printing, then change to the CMYK color model, and note down the
"equivalent" CMYK values

- define your own color library

- in your color library, define an ink with the RGB values you noted
for
display, and the CMYK values you noted for printing

- set GetLibraryColorRGBFromCMYK to "Printing"

This doesn't get you CMYK output, but it's the best you can do under
Windows. Note, however, that setting GetLibraryColorRGBFromCMYK to
"Printing" might not give such good results with the predefined color
libraries (see above).
