Simply getting a pdf only of black color (no cmy)?

[Markus 86]

Hello Affinity user,

I have a problem with creating a pdf from a publisher doc only in black for book pages. Maybe it's only the way I have to read it, I don't know.

At all I use different Designer documents with Icons inside the publisher doc. The objects inside only using black. No C, no M, no Y. Only E. G. 0 | 0 | 0 | 80. The text is also only in K. Whatever I do, whatever color profile I do use, when I open it in photo or designer the colors are all mixed in cmyk.

Do you have a save workflow what profiles and color spaces I have to use, export and open? Unfortunately I don't have Acrobat anymore and do not know a worth replacement.

I also noticed that I can not align color profiles wether in Designer or Publisher. When I click on assign and OK, the option keeps still on convert.

Thanks and best regards
Markus

Use Greyscale for the colour format. Save a copy as greyscale if needed.

I already did that for sure. Exported and opened it in greyscale, but it did'nt work. For example the text is 80 k in the publisher doc and its's profile is grey and the export color is also grey. I open it in publisher or photo than, also in grey than the colors are mixed of cmyk.

What's the best way in the affinity world to read the real colors of a document? Never had a problem like this with adobe for example.

I think what is happening here is you have a Rich Black instead of a pure black. Rich black is the result you will get when you convert black from an RGB document  to a CMYK document. For the text in your document make a 100 k black as a document global colour swatch. Do the same in your CMYK documents make a 0, 0, 0, 100 black for text as well. In all the paragraph styles you can specify the new Black for the text colour.

Yes, that is what I do. I use global colors with eg 80k in the Publisher doc. The text what is directly inside the document is complitly fine and 80k when I check the pdf in Designer for example. The problem is about embeded / linked Designer docs. I do also use only black there and global color, but when I export it, the color is mixed up in cmyk. All the documents I use are in cmyk color format.

So, I don't know why the colors of the linked /embeded objects are not only in black but in cmyk.

Are they all the exact same profile? Does that profile match the document you are placing them in to?

You are my heroe baby! I worked with the standard color profile of the documents and did'nt mentioned that at all.

Now I fixed all profiles to the same and the colors fit!
