Keri,
The first thing you want check is the profile that is attached to your PDF file and the profile that is shown in the Convert To Destination Profile area. If they are different then your 100% blacks will be converted to a CMYK mix to honor the Lab values of the 100% black in the original profile.
I have been meaning to test the different settings as we are preparing ICC profiles for our flexo presses using the G7 methodology.
In the past the values in a Photoshop patch file against the values on film (we still use film) and they have matched. This is as it should be because at the present our Photoshop images are tagged with SWOP and the Convert To Destination is SWOP. However when we start using our new profiles I will need to make sure that Prinergy is not placing its own influence on the images.
I will do some testing next week with different settings in the ColorMatch JTP and if you want to know the results let me know.
One other tip, if you for some reason you want Prinergy to convert your images and you want to keep your 100% blacks 100% black, you will have to check the Override Embedded Profiles box; the CMYK Images box; place the proper profiles in those boxes and in the Convert to Destination Profile box. Once you check the CMYK images you will be able to check the Retain CMYK Black in CMYK Images box and the CMYK Graphic box. If you are separating for press you will need to choose Relative for Rendering Intent.
The above is based on what I think will happen if those boxes are checked and what I believe the Kodak response center rep told me. My tests will confirm / deny my suspicions.
Hope this makes sense and helps.
