I created a journal page in Illustrator - which is a series of lines, some thicker than others. They have been combined into a layout for a journal in InDesign. All looks great and prints great from both programs.
When I output to PDF I lose the integrity of my lines. On screen they all look the same width (and they shouldn't), and when I print from the pdf, the thinner lines are completely gone. I have tried various PDF settings and can't figure out what is causing the problem and why the pdf isn't looking exactly like the original.
Are you printing with Adobe Acrobat? Other PDF software sometimes gives strange behavior, especially Preview.
I was using Adobe Reader (10.1.0).
