What would cause two numbers which are side by side on screen, and appear so in the PDF proof print up one on top of the other? for instance, in my last print project designed and printed from Indesign, I used a Kristen font in some areas. In a few of the areas where say I'd typed a "17" the 7 fell directly on top of the 1 making it a jarbled mess... It didn't happen everywhere, just in a few places... why and how can I fix it?
