In Regards to The "COMPRESS TEXT AND LINE ART"

In the past when we have chose this option to be checked in for our PDF
hotfolders. We had strokes in line art that were a half point completely
drop out in the PDF. For example: We create vector graphics in Adobe
Illustrator.. have a structural design for our carton layouts and use a
stroke of a half point for the structurals. We Distill using a .ps file and
the results in some of the line segments from the structural actually drop
out. Since unchecking this option this has not been a problem.
