I have a pdf I created from Quark 7. There are a number of items with .5pt rules or boxes around them (for example, business card sized ads with a half point rule). Some rules show fine and others require me to zoom in very close to see them. If I zoom in at different levels (say 100%, 150%, etc.) I may see the rule on one side only, then at a different zoom level the rule I see disappears and I see one or two of the other sides. Is this a bug of Acrobat? I'm using 9, but have seen this in earlier versions as well. Since I just sent a long document off to a printer that has this occurring, I want to make sure the rule will show and not have to fix the page later on.
Anyone know why this is happening. (I'm viewing PDF on iMacG5, but same thing happens on intel Macbook and my client's older G4.
