We produce A4 size Autocad 2006 drawings for a client who then sometimes prints them to pdf for distribution to his customers. We have
found a problem though - some (not all) of the drawings do not display on screen clearly when they are printed to pdf at normal screen size. If you zoom in, you can see the lines are all there and clear, but at full size it looks like there are gaps in the lines and text missing. If the same pdfs are printed on paper at A4 size, they're fine and everything is present and correct.
Our customer uses Acrobat Distiller, we've been using PDF995. The results appear to be the same from both.
I have studied the plot settings for 'good' and 'bad' drawings and can't see any difference. I have tried increasing the resolution when producing the pdf, but that makes no difference either.
Is there any solution to this? Any help gratefully received.
