I am using Pagemaker 7 on XP pro, and have been using Univers as the
"official corporate font" for 11 years. The Univers Type 1 font set from
Adobe comes with 8 pfb files,  UVL, UV, UVB, UVBL and the 4 oblique files.

In XP's Font Viewer, both the Univers Light and the Univers Bold files show
with the same title, Univers 45 Light (Type 1).
The Univers and Univers Black files have the same title, Univers 55 (Type
1).

In pagemaker, only 45 and 55 are listed as available fonts. I have to bold
and italicize them. Strangely, in Photoshop 7, all 4 weights are listed.

My print shop has recently installed a new Heidelberg direct to plate
system, driven by a PC (at least for my files, he has a Mac too) and the
printer has difficulty producing my pubs with the bolding applied. They all
come out as very loose, normal weight. He says I need actual 65 and 75
weight font files, which do not seem to exist in the PC world.
I managed to work around the problem for now by providing him with hires pdf
files.
Is there a setting somewhere on the imagesetter driver to accept or ignore
stylized weights?
Would this problem go away if I migrated to InDesign?
Thanks,
Rick
