: Actually, I think they outsmarted themselves... If you look at the
: Illustrator (unfortunately even AI7 eps file, you will find TWO bounding
: box comments - the customary %%BoundingBox, and also %%HiResBoundingBox.
: The latter is an accurate bounding box, whereas the former is rounded to
: the NEAREST INTEGRAL POINT.

Well, the EPS specification says that the bounding box values are
integers.  What I don't understand is why the graphic doesn't line up
with teh bounding box even at the origin.  You would think they'd
translate the coordinate space as necessary to put the lower left
corner on an integer boundary, which could then be the low values of
the bounding box.

Thanks to all who've responded.

But the 5th plate image came out offset about 1/16th" down and to the
right WITHIN the bounding box on this one file. Doesnt show on-screen.
None of the other files did this. Arrgh.

The pre-press guys at our service bureau took one look, and said "Runaround!".

Huh?

Turns out "Runaround" was set to "auto" on that bitmap in that file
instead of "none" - how, I don't know. It should'nt have been - my
preferences are set to create all new image and text blocks with "none".

So, anyone know WHY? It doesnt matter - its just another pre-flight item
for the checklist (which keeps growing and growing all the time), and easy
to catch, but it puzzles me as to why it does this. Anyone have any idea?
It's annoying, like how Quark does NOT update bitmap Tiffs (Just bitmap
tiffs) correctly when the link to the files have been broken ( like if the
files have moved directories) - but this one makes no sense to me at all,
as Runaround should only effect TEXT below or above the image, not the
image itself!

I won't pretend to understand what you guys are talking about, but in the
same vein, I just had a Quark 3.32 doc with an Illutrator 7 eps that
wouldn't RIP.

The error looked something like this:

UnKnownDict
AGM Gradient private
Adobe Illustrator AI5 vars
Adobe Illustrator A15
Adobe ColorImage AI6
AGM Gradient
Adobe screens AI5
Adobe cshow
Adobe level2 AI5
UnKnownDict
epsdict
QuarkXpress 3.32
md
userdict
shareddict
systemdict
[Error: undefined; OffendingCommand: optimize]

The doc wouldn't rip until we removed the object with the  blend. From the
discussion, it seems like Adobe is messing with Postscript. Any ideas?
