Pantone C vs CVC / Screen printing : RESOLVED!

[mathieu jacquet]

Yves,

thank you for your help. 

I followed "solution 3" of the Adobe TechNote ("solution 1" being already partially done by importing .eps files into my template, and "solution 2" using a plug-in I do not have), which consists to set the GetLibraryColorRGBFromCMYK option to "None" in the Maker.ini file. 

Everything ran smoothly afterwards.

Thanks a lot and have a nice day,
Mathieu.

In Frame, you can specify colors in the Paragraph Designer and the Character Designer, but also on Reference Pages, Master Pages, tables and what have you. And you may even import EPS line art which has similar, but different colors. All of these can be checked, managed and corrected in the PDF.

I have looked into the FrameMaker colour library and found a Pantone 246 CVC, which is, as I have read here and there, identical to 246 C but for computer video, whereas the 246 C is for coated paper printing.
