Pantone C vs CVC / Screen printing

[Yves Barbion]

Hi Mathieu,

assuming that you're using Frame in Windows, this is what causes the
problem:

You can try the workarounds which are described in the above article, but be
careful with color conversions, e.g. from RGB back to CMYK. I'd use a color
remapping instead.

This is my workaround:

   1. I create custom colors in FrameMaker, for example "company color 1"
   and "company color 2".
   2. I specify CMYK values for these colors, although they don't really
   matter here because they will be converted to RGB in the PDF anyway.
   3. I Acrobat, I use Enfocus PitStop Professional as a plug-in.
   4. Using Enfocus PitStop, I create an Action List (or a PDF profile) in
   which I set up my color remapping scheme to remap all RGB colors with
   specific RGB values to a specific Pantone color (or CMYK).
   5. I generate a preflight report to check (and correct) the colors in my
   PDF document.

This is the only way in which I can assure color consistency and fix
incorrect colors globally. 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.

Kind regards
