How do I create a "high resolution, print ready PDF file?"  I normally make a regular PDF, and we have no problem, however, we must send out a file for a local printer to produce.  The printer said they could not use our PDF and asked for the high resolution PDF.  I changed the options to "High quality lines Shaded/Draft geometr DPI to 600, but that did not increase the file size very much.  Can you shed any light on what this printer is requesting?
