Why is FrameMaker using different CYMK/RGB values for Pantone library colours compared with Illustrator?

Question

Evening all -
this is by no means the first time I'm banged my head against the colour management brick wall, and I doubt it will be the last
I am running Frame 12 and Illustrator CC on Windows 7.
Both these Adobe products ship bundled with Pantone libraries. (Correct me with I'm wrong, but these "libraries" are basically a bunch of look-up tables, mapping named Pantone colours to various CYMK, RGB, etc equivalents?)
Can anyone tell me why these two different Adobe applications appear to give different definitions for the same Pantone colours?
For example, if I choose the Pantone Coated library > 'Warm Red'
In Illustrator CC (left screenshot), it offers this as C0% M87.4% Y79.9% K0%
in FrameMaker 12 (right screenshot), I get C0% M79%  Y91%  K0%
Why are they different?
Are the library definitions shipped with the products simply different?
Frame's dialog ominously mentions "© Pantone, Inc., 1986, 1988"
And if I go to C:\Program Files (x86)\Adobe\AdobeFrameMaker12\fminit\color and open the corresponding .bcf file in an editor, the header says:
"BCF 2.0PANTONE¨ Coated 1.1 ©Pantone, Inc., 1986, 1988.PANTONE¨* Computer Video simulations displayed may not match PANTONE-identified solid color standards.  Use current PANTONE Color Reference Manuals for accurate color.  To order publications from Pantone, Inc., in the U.S. please call the toll-free number [phone] [within NJ, call [phone]].  In other countries contact your local Pantone representative.  *Pantone, Inc.'s check-standard trademark for color.[1]"
whereas if I go to C:\Program Files (x86)\Adobe\Adobe Illustrator CC\Presets\en_US\Swatches\Color Books and open the corresponding .acb swatch file in there, in amoungst the hex gibberish I note it says:
"�=$$$/colorbook/PantonePlusCoated/title=PANTONE+^R Solid Coated/$$$/colorbook/PantonePlusCoated/prefix=PANTONE *$$$/colorbook/PantonePlusCoated/postfix= CK"$$$/colorbook/PantonePlusCoated/description=Copyright^C Pantone LLC, 2010"
Have Pantone perhaps changed their colour definitions between 1988 and 2010?
(I'm thinking it would be sensible to establish this one way or the other before we get into any convoluted discussions about the Windows GDI etc etc)

Answer 1

David,
What options did you use for defining the colours internally and what options for output in AI? I suspect that if you examine the EPS file you created from AI for the Panotne 355C, the only values in there are the CMYK ones - no LAB nor RGB. So FM has to use the algorithm mentioned in the other thread and creates the lime green based upon the algorithm. If you have set the AI drawing to an RGB color mode and set the EPS export option for "Include CMYK Postscript in RGB files" to OFF, then you would get the desired RGB values in the EPS file.
If you're so intent on using Pantone Spot colours to get RGB, then you can create your own ACF library file with the exact RGB definitions that you want (you can then use whatever values you get in Photoshop, Illustrator or whatever source that you're trying to match). The structure of the file is as follows:
ACF 1.0
My Color Library             <----  name of library
LibraryVersion: 1.0
Copyright: © 2014 <your name here>. All rights reserved.
AboutMessage: User defined Spot colours for RGB
Names: Partial
Rows: 4
Columns: 4
Entries: 1           <---- number of colours in file
Prefix:         <---- used for display in FM, e.g. "Panotne"
Suffix:           <----- used together with prefix, e.g. "CVC, CVU, etc."
Type: Process <---- Spot, Process, Tint, Mixed (need to add specifier to Data lines)
Models: CMYK RGB
PreferredModel: RGB     <---- whatever you want
Data:
0.98 0.11 1.00 0.02              <---- CMYK values (0-1)
0 38143 19967     <---- RGB values as 16-bit, i.e. 16-bit = ( [RGB value (1-255)]*256) + 255; zero is still zero
Spruce Green                   <---- name of colour
The acf file needs to be installed in the fminit\color folder.
Also, a note of caution, If you screw something up in the acf file (like the incorrect number of entries in the file or you're missing a component value, this will hang FM if you use the View > Color > Definitions... option. You'll need to kill FM, fix or remove the ACF file and re-start. Also, FM only reads the libraries at the start, so if you need to make any changes to the ACF definitions, you have to r-start FM for those changes to take place.
[I know, FM doesn't make it easy, but it can be done...]
