One customer reported that a PostScript error, offending command "save"
was caused by a corrupted image on the page. Replacing the image solved
the problem.
Nesting files (e.g. putting an EPS in another EPS, placing that EPS on
a page, exporting the page to PDF to put it on another page and then saving
that final page as a PS-file to impose it) can also lead to 'save' errors.
Avoiding excessive nesting while creating or processing documents is always
a good idea. Since it is sometimes impossible to know which images or
other elements already have other files embedded within them, selectively
deleting elements and reprinting the document is sometimes the only way
of finding the bad element. |
