Grayscale text or CMYK in Publisher?

[Tim Be]

I set up a new document (for a paperback book) and chose grayscale/8 in the initial set-up box. But when I add a text frame, it is CMYK with values of 72-68-67-88. Is this correct, or should I change the text box’s setting to grayscale too?

And while I’m here, are those the best CMYK settings for type, or should it be 0-0-0-0?

Thanks.

Ok. So, the short story is, I don't need to do anything now while making the document - just leave it all as is - and be sure to check those export settings when that time comes. Is this right?

Indeed a confusing workflow. While the button "K Only" in a CMYK document takes from an CMYK image its black channel only I would expect in a Grayscale document that using 0 0 0 100 would cause the same and result in 100 K if exported as grayscale. – Instead it appears that a CMYK black (100 K) in a Grayscale document exported as grayscale PDF can result in quite different values for 100K within 1 exported PDF.

For instance an export as PDF 1.7 + image colour conversion contains 85, 86, 90, 94 and 100% and gets the 100% only for RGB and Gray color definition but never for CMYK, even if it is the Affinity rich black / RGB equivalent.

Or another export, e.g. as PDF/X-4 (without image conversion) results in 4 different values for 100 K: 95, 98, 99 and 100%.

It feels quite strange that in particular CMYK causes those differences in a Grayscale .afpub while RGB (000) seems to be no question.
