Thanks Refik. I checked and my version of Acrobat X is fully up to date and seems to work fine now. It was just that one Preference Setting (smooth line art) that was messing up the display of the files that my printer sent to me. Lou ------------------------------

Dear Lou,
The inital release of Acrobat Pro X (version 10.0.0) had problems with regard to soft proofing a PDF file, even in you had all the Preferences/Color Management settings correct on a properly calibrated/profiled display. What you need to do is to update it to its latest version, which is 10.1.13. Following the update it should do a decent simulation of the printed image.
Let's assume that you receive a print ready PDF file from your premedia house prepared in a FOGRA39L dataset based CMYK colorspace, such as ISO Coated v2 (ECI), and that you have a display calibrated/profiled to a white point in the 5800ºK to 6000ºK range, a gamma of 2.2 and a luminance level of 100 nits (cd/sqm). The monitor white is a good simulation of the paper white under D50 illuminant and the color image a is good representation of the printed image. Adobe does a sloppy work when simulating Paper Color and Black Ink, hence we do keep these functions switched off.
Just make sure that the CMYK colorpace set in the Preferences/Color Management and the Simulation Profile in the Output Preview (if open) are the same that is used by the premedia company when constructing the PDF file.
Best,
