I want to better understand ICC profiles and colour spaces for perfect printing results

[Hussard64]

Dear,

When I want to submit for the first time my print request to the printing services, they mentioned that I have to export the PDF to submit by referring to CMYK colour scheme with the ICC profile Fogra 39. I suppose that I just have to select the settings as mentioned on the screenshot, please confirm.

Can you also tell me where I can find a detailed explanation of the ICC profiles and colour spaces and their influence/role in printing results?

 

Regards,
Frank

BTW, what means Uncoated  in front of Fogra29 ICC selection?

Coated paper is "shiny" Uncoated paper is "matte/dull/plain"

Think of the difference between Glossy Magazines and Newspapers.

A more safe workflow in Affinity is to keep both export options "as document" and adjust the document colour settings before export instead. If your document contains black text you may have assigned 100 K (with CMY = 0). To preserve colour values already set in the Swatches or Colours Panel choose the option "Assign" when selecting a different profile for your document.

Simply spoken they adjust document colours according to the printing process (machine / paper). For instance a coated paper may require less ink compared to an uncoated paper, a yellowish paper requires less yellow ink.

Just to note that you mention Fogra 39 but your screenshot is Uncoated Fogra 29.

For French speaking persons, the reference website is probably the one created by Arnaud Frich. With years passing it has become quite dense but it's very complete :
