Is Publisher now able to passthrough colors when exporting PDF?

[ericosmosNEW]

I'm still reluctant to using Publisher for professional print purposes, since it hasn't been able to preserve the exact numbers of color separations I set up in Photoshop (exported as cmyk TIFF), not possible in Affinity Photo anyway...

Is Publisher now able to do that after the Update? Otherwise I'd still be bound to InDesign.

Thank you so much for this detailed answer. Means for me, still not reliable for what I need unfortunately.

While being somewhat happy with Affinity Photo and Designer for creating pages of graphic novel art, it looks like I will have to stay with InDesign at least for putting all pages together as a magazine and sending it to print.

Maybe I give it another shot. I remember one of my tests (placing Designer into Publisher and export to PDF) produced a result that kept the color separation intact. Might have been the press or print ready version 🤔I'll have another look.

The original PDF 1.4 file containing transparency and created in Affinity Designer (the color values are shown correctly in Adobe Acrobat):

The file placed in Publisher to be passed through and exported with "PDF (press-ready)" preset using PDF version 1.4 (confused color values shown in Adobe Acrobat Pro, unless Object Inspector is used):

If this file is opened back in Affinity Publisher, the correct color values would be shown, but how trusful preflight would that be? And this kind of check cannot show e.g. the overprint state of colors.

I seem to have a similar problem. Every export from Publisher (with placed Designer file in it) resulted in wrong color separation (I want less blacks and mor cmy in the values -> hence UCR). When I export directly from Designer I get the the correct color separation (numbers preserved as it seems).

@Lagarto when you check the black plate in my attached PDFs you see that the "fromDesignerUCR" files has significantly less black than the Publisher export PDF, even though it's exactly the same Designer file but placed in a Publisher document.
I'm not sure if Packzview would show anything different, but I doubt it in my case.

Well, I didn't place a PDF (exported from Designer) into Publisher, but rather placed the actual Designer file into the Publisher document. Isn't that the way it is supposed to work? This way I'm still able to make changes to the designer file that autmatically is in the publisher document as well.
But, it seems to mess with the color separation if I do it this way...

I could send you the original designer file. Maybe I just haven't ticked the right toggle in the export window ... I don't know.
If you can find a way to export it from Publisher with the color separation as seen in the "from DesignerUCR" file ... that would save my a$$ 😄

As I said earlier, that's the reason, why I'm reluctant to use Publisher for my print purposes.

I give it a try. Just a sec

By the way, I tried the artboard option in Designer for compiling all my pages in one Designer file. Exported it to PDF. Same problem like Publisher. Color separation messed up.

Slowly running out of options… 😑
