I have a client who is using a digital off-set printer. All files are saved to a Photoshop PDF. They have blocks of colour and one is pure black. No matter what I send to the printer, they keep telling me that the black colour codes are not 0%, 0%, 0%, 100%. This is the first I have ever heard of this.
HELP!!!
#1
How EXACTLY are you creating those files? What version of Photoshop and why PDF?

The files were created in Photoshop CS2 by an employee that is no longer here, so I have taken over the project. They were saved as a PDF at Press Quaility Resolution because they said that Press Ready PDF's were adequate for printing.
The blocks of black are a Shape from the shape tool.
Does that answer your question?
#3
I have sampled the black after saving the PDF, and it still shows up as C=0%, M=0%, Y=0%, K=100%.
#4
Can you post the file somewhere? Or...if it's under 20 megs you can email it to me.
Click my name, go to my website and you'll find my contact info there.

File looks good to me. The printer must be doing something funky with it like rasterizing or placing it in Quark.

It sounds like he (or you, I haven't seen the files) must be doing something with colour management and profiles. Quite likely placing/opening the file wrongly, as Bob said.
Have you tried saving the PDF as a PDF/X-1a?
