0/0/0/100 in CMYK will convert to use all colors when saved as PDF

[js8]

Brilliant choice, Affinity Publisher!

LITERALLY impossible to force ink to be black only. Do you think this will make people use your shitty software instead of the almost-as-shitty InDesign?

If you clear the ‘Embed profiles’ checkbox in the Export dialog, you should find that PDF export retains black as K100.

No it doesn't. Just tried. The "convert image colour profiles" checkbox is also unticked.

No other software does this. I've fixed the text now (the fill was NOT in the colour tab, because that would be logical). But any image, even if I convert it beforehand in Photoshop to 100% K, will be converted to use colored inks. This is a nightmare.

To send to the printers, I have to have an ICC profile embedded, by the way.

Edit: Using the images as psd works somewhat. It still leaves like 5% cyan, which is stupid, but at least it's not trying to convert them anymore.

Some screenshots would help. And a sample .afpub document.

Text should be fine if you make sure you are using a 0/0/0/100 color for it from the start. It's too easy to find and use the wrong black, and that should be improved in the applications.

For images: if you're talking about black & white images, look for a K-only button on the Context Toolbar.

Are you using 0 0 0 100 cmyk colour in an RGB affinity document? That is the only thing I can think of that would be causing this to happen.

K-only button? What's that? What's the context toolbar?

I've highlighted the K-only button on the Context Toolbar here:

 

And here is the result of clicking it:

That image will use only the K ink in a CMYK document.

Hello,
I think you have to choose the option 'use the document profile' which avoids a conversion and thus keeps 100% black
