black in CMYK-PDF

[RaiStr]

When export a file in 100% black, I should have a CMYK 0/0/0/100 in PDF. In the moment I only have 63/68/60/79 for a black wich is defined with 100% in Publisher.

I think its a bug.

What application are you talking about? Photo (this forum) or Publisher?

[fde101]

Agreed, it sounds like this might be posted in the wrong forum, however I believe that part of the engine is likely common among the apps - consider that the color could be set in Publisher then the document opened in Photo later for printing.  So this may well be a bug in common among the three programs.

Just test it: A K=100 color renders identically in a PDF exported from Publisher. Therefore my question.

Sounds like a colour profile issue - double check your working profile and output profile are the same

Yes, I think, there are differnt profiles in the game, what may cause a CMYK-to-CMYK-conversion.

Check your Colour format (Document Setup > Colour tab) - if that's set to RGB, you can still specify a CMYK colour, but your 100%K will get converted to RGB when you export a pdf, opening up that pdf and checking the CMYK colour of your black will give the sort of value mentioned (63/68/60/79).
