Apologies in advance if this is not the right newsgroup(s); please tell me
where this query would be more appropriate.

I'm looking for any information about the OPI (Open Prepress Environment),
reputedly from Aldus, supposedly consisting of an extension to PostScript
comments and some other stuff.  (As you can tell, I don't know much about it).

Does Aldus have a fileserver or an e-mail address I could contact them at for
further information?

Please email to me, and I'll summarize if this actually turns out to be of
interest.  Not only is this a fairly constrained topic, I don't normally get
these newsgroups at my site.

Everything I know about the Open Prepress Interface comes from
an article I read last year in the _Seybold Report on Publishing
Systems_, Vol. 20, No. 17, ISSN: 0736-7260, May 29, 1991.

It is simply a convention for embedding instructions into PostScript 
files to tell the output device where and how to merge various text
and graphics components of a page.  The components themselves are
PS files that may have been composed at different times on various 
computers.  

It has its roots in Aldus's PageMaker.  Its main trick is to let
users manipulate low resolution images on their screens, for
editing, cropping, color correction, etc., and then reference
the full resolution image, with all the modifications, to the
printer.  Its designed for high resolution image setters and so
won't help folks who want to stick to 300 dpi as much.

Contact Aldus for more info.
