Thanks Catshill. I'm using the 75,68,67,90 black on the cover, which will be printed in color. The interior of the book will be printed on a black-and-white printer, though, so I thought it was better to use K100 black. But I'm confused why the K100 image (using the K only button) and the K100 text in my document look different once exported to PDF.

Hi all. A follow-up question: are text and image blacks handled differently? I set both my text and images to K100 black. This is confirmed by the Affinity Publisher color sampler. However, after exporting to PDF, the text is a very dark gray instead. The Mac Digital Color Meter identifies the image as 0,0,0 RGB (black), but the text is 26,25,25 RGB (dark gray). Any ideas?

Fantastic, thanks @lacerto and others! I found the K only button, and it appears to do exactly what I want. And yes, the "Add Preset" button appeared once I installed Affinity Photo. (I already had a license for it, but hadn't install it.) Thanks again, all!

Hmm, my document is CMYK, but I don't seem to have a K-only button. If I use the "Black and White" adjustment, I get a K value of around 93 by default, while moving all of the sliders to -200% gives me values of K to 98. I can add a second adjustment (using Levels and Multiply) to get K to 100. Is this a good option? If so, can I save these two adjustments as one preset? I don't seem to have an "add preset" button either. If anyone wants to take a look, I've attached a page below, with the adjustments described above. Any advice? sample_page.afpub

Thanks @firstdefence. That website suggests a "rich black" value of 75,68,67,90. Does this recommendation change if my book is printed on a black and white printer? Since the interior of my book is only grayscale (pretty much just black line art), I'm using the "black and white" interior option from KDP. Does a black and white printer use the CMY values, or only the K?

Hi folks. I'm making some coloring books with KDP, but I'm a bit confused about the color black. The book's interior is printed in black and white, and my document has a Generic CMYK color profile. I've set the book's text to be K100 black (0,0,0,100). I also drew line-art illustrations in Procreate, saved them as png, then imported them into Publisher. The CMYK values for the black part of the illustrations is 75,71,65,80 in Publisher. Will this show up as dark black once printed, or more or a gray? I'd like both the text and images to be a nice dark black. Any suggestions? Thanks!
