Colour management when exporting PDFs for the Gelato print-on-demand service
I'm using Affinity to export an SVG as a PDF to upload to the Gelato print-on-demand service for printing as a poster. I'm working in RGB. The guidance on the Gelato support pages is:
"RGB Workflow: If working in RGB, tag your image files with an sRGB profile. When exporting, save them as PDF/X4 files with a "GRACoL2006_Coated1v2.icc" output intent to maintain color fidelity."
Does this mean that, in document setup, I Assign the Colour format as RGB/8 and Colour profile as sRGB IEC1966-2.1 [which is the only sRGB profile I seem to have]. Then, when I use File - Export - PDF/X-4, I should change the drop downs for Colour space and ICC Profiles respectively from "As document" and "Use document profile", to "CMYK" and "GRACoL2006_Coated1v2.icc". [I don't seem to be able to make the GRACoL... profile available without setting the Colour space to CMYK, by the way].
I'm a bit new to Affinity so would appreciate if someone with more knowledge could confirm I'm doing what Gelato are asking for, or put me on the right track if I'm wrong?
And as a follow-up, is there any way I can interrogate the resultant PDF file to get some assurance it has been set up the way Gelato are asking for?
Cheers!
