I have created an application that produces CMYK documents. They print well in "Microsoft Xps document writer" and are still in CMYK and carry the exact color values I've designed in my application.
When I repeat the printing into Adobe Pdf, the CMYK values change. This is unwanted behavior, I want my exact color values retained. I've tried setting the "color management policies" to "leave color unchanged" with no success.

Any help will be appreciated

As it turns out, the following is a solution to this problem:


edit adobe pdf printer color settings to "do not change colors"
and then save these settings to a .joboptions file.
Go to acrobat settings, in "Convert to Pdf" select "Xps" and then
click "edit settings".
Select the settings you've saved in step 1.
4-Print your Wpf content to "Microsoft Xps document writer" to get
an Xps file
open the Xps file directly in acrobat and save it as pdf


Done!

You can use acrobat sdk which is freely available from adobe website, to automate this process (unfortunately acrobat has vary limited command prompt options, so using the sdk seems to be the only option)

Microsoft XPS has a different colour engine from Adobe PDF. It is unlikely that a document produced in one will play nice with the other. The XPS is non-standard. Adobe PDF X/1a has become the de facto standard for Press-ready PDF formats.

Edit: Here are your options:


Accept the difference in colour due to using your software
combination.
Stick with XPS (using Microsoft Xps document writer) to preserve your
design integrity.
Redo the artwork to avoid the inherent problem in different colour
rendering.
Locate a suitable XPF to PDF Converter to ease one into the other. There are several that come up with a search.


Good luck.
