1.4.1. Where PDLs fail in principle
In principle some documents can not be correctly converted into
PostScript, for instance MS Word documents containing WordArt objects (for an example please click on
the following link, www.DriverLab.de/EXTIFpro/TestDocums/WordArt.doc.):
Above:
Correct printing result with EXTIF pro: not transparent in the overlaid
areas, just as in the original document.
Below:
Incorrect result in PDF (created by the most famous PDF converter on the
usual indirect way via PostScript): transparent overlay area; two overlaid opaque areas
resulting in erroneous transparency.
Another example:
Printing
from within Adobe Acrobat in principle is restricted
to 2^14=16384 Pixels, along vertical as well as horizontal coordinates, meaning
that, for an A2-sized document with a resolution of only 900 dpi, some areas at
the right hand side and at the bottom of the page remain erroneously unprinted.
This
error does not appear when printing the same PDF document from within GhostView. Nevertheless, GhostView does not provide color separation, turning the
situation into a perfect dilemma.
