I am creating a menu in Indesign cs5. When I try to print the file, be it as an indesign file or as a pdf from acrobat x I get random vertical lines in letters where I used gradients. Any Ideas on how best to remedy this? I've seen some info online suggesting that flattening the image can fix postscript issues but I am not really sure how to do that or if it would even help. If it is of any help I am printing on xerox 700 digital press using creo rip software.
to flatten the pdf > in the Export PDF dialogue box > select compatibility Acrobat 4 (1.3)
I tried exporting the pdf as acrobat 1.3 but the lines are still there.
