RE: PDF Blues

[Dov Isaacs <isaacs@xxxxxxxxx>]

Kevin,

Contrary to what you imply, FrameMaker does absolutely nothing
to EPS graphics other than to display the EPS preview header and
to pass the PostScript within the EPS out to the output PostScript
stream unchanged!

Thus, this is NOT a FrameMaker issue, but rather one of either
PDF creation or creation of your original artwork.

There could be any number of reasons why the resultant color
could be problematic:

(1) You need to turn off any and all color management or tagging
options in the Distiller joboptions, i.e. "no settings" and 
"leave color unchanged".

(2) You also need to know what really is being selected as a
color in Illustrator. Remember that the screen color gamut is
very different than that of CMYK printed output. In Illustrator,
you might want to turn on the color preview option and see
whether that yields that "slate-blue-grey" in lieu of the 
"nice dark, midnight blue" you crave. If so, you may need to
change the color you use in Illustrator.

Note that I would not personally recommend importing PDF
directly into FrameMaker. In the case of Illustrator 9, normally
PDF 1.4 is exported; FrameMaker 6 can only deal with PDF 1.3.
Why for one color it looks "better" I don't know. However, what
is REALLY going on is that FrameMaker converts imported PDF
into EPS and based upon your maker.ini settings, it may be
better matching your intent in terms of color rendition. But
that is only a guess without actually seeing samples of what
you are talking about.
