... a mess. I like Publisher, a lot. But setting up a greyscale document is (right now) a catastrophe ... to me. But maybe I am too stupid, so here is how I start:

1. File New, Colour = Grey/8, Colour Profile = Greyscale D50.

2. Typing in some text and creating a rectangle.

3. Nice there is a Greys Palette (Swatches panel), so apply Black to the text and rectangle.

4. Export PDF for Print and opening with Acrobat Pro.

Result 1: What is meant to be BLACK is C83 M67 Y51 K95! Sending the file to a print service will end as disaster.

5. Too bad, my fault? Going back to the document having a look at the colour panel. First shown is the RGB slider with values 0,0,0.

6. So I use the CMYK slider having black only with 100%.

7. Repeat Step 4.

Result 2: What is meant to be BLACK is C74 M63 Y50 K89! Sending the file to a print service will end as disaster+1.

6. Too bad, my fault? Going back to the document having a second look at the colour panel. Picking up Greyscale from the pulldown.

7. Seriously? The value of 0 at the slider means 100% black? Value 70 means 30% black and value 0 means white? So why not.

8. Repeat Step 4.

Result 3: See Result 1.

Final conclusion: If I ever want to send a greyscale document to a print service I have to set up the document as CMYK. From my point of view this should be fixed. While you (Serif) are at it, please give "colour management" a re-design = Switching between colour spaces (spot to cmyk to rgb to spot whatever) + Iconize the colours to make it visible what colour space they are + A colour manager before export or print like in Indesign where you can define aliases for spot colours for instance or some other helpful settings. I do know this is BETA, but a stable Affinity Designer 1.65 has the same problem.

RGB and CMYK are in two different color spaces.  I believe the swatch palettes are all set up in terms of RGB right now, so Publisher is trying to convert that RGB (0, 0, 0) through color management to the relevant CMYK value and landing on what you are getting.

The standard swatch palettes should really be made smarter about adapting to the different color spaces.

In the end it means I am not able to produce a correct greyscale document? And this behaviour for the complete range of Affinity products? For products meant for designing a no-go. :(

The problem only occurs here if I use a PDF/X compatibility. I'd guess these are purposefully designed for CMYK printing only. If I use a PDF 1.4 to 1.7 then these keep the PDF as greyscale. I think APub is working correctly.

Thanks for this post!

Joachim - how did you check if the black is realy black? This is next big issue with Publisher, if it can't export black as a black :( This is the next reason, why I have to redo whole my actual project in InDesign. It will be crazy and timeconsuming work, but now the final result is important and I can't afford to send this to the client with this.

And one quick note. Try to swicht off the "overprint black" in export settings. 

If I leave it switched, export pdf and then reopen this pdf in Publisher, the black is something strange (all CMYK channels have some value), but after switching off this option, the black is C0 M0 Y0 K100.

I (have to) use Acrobat Pro with the Colour Output panel, since there is no option (like previewing colour separations) to check this in Publisher right now.
