Acrobat PDfs...missing pixels...zippers

[Doit]

:roll:
I'm creating pdf files by postscript from CS Illustrator, then taking postscript
to Distiller...customer requires this procedure... doesn't like the size of save as pdf from Illustrator...my Acrobat and Distiller are 6.0.2 (waiting to be able to upgrade to 7):
problem: CTs and or gaussian blurs have horrizontal line streaks and
bounding box ghosts that displays in the pdf file; they don't appear
when I print to my Konicas, but, do appear as tiles on my Epson Pro
4000. These are cmyk and spot colors respectively, I've tried
embeding CTs...taking gaussian blurs to CT layer and rasterize as
one unit...600ppi (customer requires hi resolution) this does
work....for now... my files are small, just PDP panel, but it makes
my entire graphics file HUGE
question: has anyone else had this situation, is it an easy fix, or is it an
upgrade issue?

You can greatly reduce the file size of PDF's from Illustrator be deselecting "Preserve Illustrator Editing Capabilities" in the Save Adobe PDF dialog box. What Illustrator is doing when you have the preserve editing option selected is making a file that includes the pdf info AND the Illustrator file.

Flattening of transparencies in your current pdf workflow is what is causing the artifacts you mentioned. I would leave the transparencies "live" as far down the workflow as possible and ideally let the rip on whatever output device flatten it for final output.

Hope this helps.

as angstboy said, if you turn off the illustrator editing stuff the pdf becomes smaller, but, why not just print to pdf from illustrator with the correct settings, should flatten properly, it is the best way to go.
