Context:
I am preparing a design to be sent off to a professional printer. I will print the exact same design on both coated and uncoated paper, requiring FOGRA39 and FOGRA47 respectively.

In InDesign, I have set up a document including this color: CMYK(0,0,0,10), a light grey.

My workspace profile for CMYK is FOGRA39. When manually checking the PDF-X, the color is correctly defined as CMYK(0,0,0,10). When assigning and converting the PDF-X (during my InDesign export) to FOGRA47, the color changes to CMYK(7,5,5,0).

Question:
When assigning and converting colors from one profile to another during export, is InDesign trying to achieve color appearance? Or should I only assign the color profile to achieve the same color appearance on both versions of the printed product?

EDIT
The goal is the achieve "the same" color appearance on both papers.

Thank you a lot!

    What is your goal? Shall the output on uncoated and coated paper look the same? Apr 29, 2018 at 6:57
  • @StefanBollmann Yes, the goal is to have the same color appearance on both papers. Obviously, the color shift between profiles seems to be quite subtle here, but I would like to know in general, when more significant differences between profiles exist, how do keep the same color appearance on different types of paper?

  • @DerGoliHerr what you describe can be one of many things. You might be using a perceptual or saturation, intent. See color management si not really all that complicated IF you can make the same colors, the problem is rather what happens when you can not.
