Affinity Pub: exporting to PDF with pure black text v. rich black text

[Peter Falkenberg Brown]

Hi All,

I've been experimenting with exporting to PDFs with pure black text (cmyk: 0,0,0,100) versus rich black text (cmyk: 60,40,40,100).

I set a couple of lines of text in each of the values, for comparison.

When I print to a Brother laser printer from within AP, the rich black is vivid and sharp and the pure black is grayish with visible dots (like newsprint) under a 5x magnifying glass.

=> However, when I export that page to a PDF (PDF/X-1a:2001 or PDF/X-1a:2003), it looks like the rich black is downgraded to pure black and when I print from the PDF, there's virtually no difference.

This is perhaps not important or relevant for inside black text pages, but for black on covers, I would think it would be important.

Checking the box for Overprint Black made no difference with the PDF's black quality.

I've tried it with the color space set to Gray/8 as well as CMYK. No difference.

Am I missing something?

Thanks,

Peter Brown

Sorry to hear you're having trouble!

Are you able to provide a copy of your .afpub file, and the exported PDF file please?
