Hello,
forgive me if I'm raising this subject in the wrong forum, but I found it challenging to find the correct one.
This issue has bothered me for a while. If I'm creating a document specifically for publication in print form and it's in colour, I absolutely understand that it must be set up in CMYK, and exported to PDF also in CMYK. But what is the absolute correct setting when exporting a document intended for print that is in black & white. I have one printing company that I use that says it too should be exported in CMYK, and another that says it should be exported in greyscale. Admittedly, when I've chosen the advice of the former, the finished result (physical copy) is that there is not a rich black appearance; rather it comes out more on the 'brown' side. And exporting in greyscale has produced a better result.
But now I'm confused, because in Affinity 2, when I hgo to set up a new document in greyscale and try to export it, I'm getting the pre-flight warning of 'Document colour profile not suitable for PDF/X'. This is suggesting to me that it's not correct to have even set up the document in greyscale.
I'm really hoping to resolve this issue that seems to be so divided. For Black & White publications what is the best setting recommended in colour profile for both:
1. Document set up
2. Exporting to PDF
Thank you in advance,
Peter
