High-res PDF gets striped

[Moltas]

Ahh, long time no see. I'm glad to see that this wonderful place looks more alive then ever!

Well, now to my Q. My wife works in a print shop and she has been working with PS for a few months. And now she stumbled upon a problem. As the heroic husband I am I promised to help her out. Now, gathering the forces of good I hope for a happy end...(yes I just saw the Incredibles)

She creates a gradient from 0% black to 100% black. The area is an A4 (210x297 mm). When she save this image as a high-resolution PDF the gradient gets striped. Both when viewed and when sent to the rip. Are there any secrets yet to be revealed about the PDF export?

Hi Moltas

I really can't answer your question but have a thought or two. When the gradient is drawn, if the Gradient tool is used is Dither turned on in the Tool Bar? That might make a difference. Secondly, maybe 100% black to 100% white might make a difference (assuming the original gradient is drawn on a white background).

Thanks Welles. I'll pass that info on. I'll let you know if it helped.
