I have drafted drawings sent from a customer who exports all thier CAD drawings to a PDF. They will not send them any other way. We use these drawings to produce their parts. The lines are so dark and thick that I can not tell where the dimensions go to. I hit ctrl-5 and it looks good, but still does not print on any of our printers. I turned off "Enhance Thin Lines" and again it looked good on screen, but printed poorly. Does any one know how to get the lines to print out thin as on screen?
