Horizontal Lines when I print to PDF

[MikeKos]

Printing some larger, more complex DWF files to PDF -- especially when I print to

a larger "page" format, above ANSI or ARCH "C" size -- produces areas of gradient

that are streaked through with horizontal lines. The lines are white or light gray, a

couple of pixels high, and separated from one another by bands of the correct

color, also only a couple of pixels high.

Anyone else ever see that kind of printing error? I can usually Photoshop the

streaks out, without a whole lot of extra time and effort -- but it's such a

consistent fault. Only happens going DWF to PDF.

FWIW, I have a Win 7 64-bit box with lots of extra RAM, a good graphics card,

and Acrobat Pro Extended version 9.5.2.My Design Review version is 13.0.0.63.

Same issue here. Anyone found a solution for this problem?

It's not really a solution but if you have Adobe Illustrator, as well as Photoshop, there is a workaround.

I've found that opening the  PDF in Illustrator, instead of Photoshop, then exporting to a high resolution TIF  (at least 350 dpi, sometimes 600)  allows for a much better import to Photoshop. When you have a clean TIF in Photoshop, you can then re-size and re-save to a crisp jpg or png or whatever.
