Document created in CorelDraw with some Type 1 fonts and EPS art and printed to Adobe PDF (from Acrobat Pro 8.1.0) as Standard quality PDF.
When using Adobe Reader 8 to print the document to laser printer (several tried) the type and the EPS art is very poor quality--like a coarse screen. Same document printed to a postscript laser printer prints perfectly. In earlier versions of Acrobat Reader the difference between true PS and the rendered type was virtually indistinguishable on laserjets. I'm only an occasional user, but have been so over a decade or more and never encountered this. What happened? Is there some setting that I am overlooking?
I did manage to find what the problem was, but I don't fully understand it. It is on the Corel side, however, not Adobe, and has something to do with how CorelDraw defines "black". I had set the problematic fonts and the EPS to be basic Pantone Black, which seemed appropriate. It turned out that the coarse screen effect seemed to be Corel's way of interpreting that. I switched the fonts and the EPS art to the RGB pallete and set it to a Black made up of 100% and then they came out just fine. I don't understand why CorelDraw didn't think Pantone Black is Black, but I've got a work around, though I think my days with Corel are numbered.
