Problem plotting solid hatches to pdf

[beafish]

I'm creating solid hatches which look fine in autocad and they look fine when I print them out on my printer. However, when I plot it to pdf, the solid hatched area is littered with scratchy lines. The hatch is just supposed to be a solid black area, but it's covered with these solid, dashed and dotted white lines. What's going on??
I'm running autocad 2007 and plotting with adobe acrobat pro AND Amyuni pdf converter.
Thanks in advance for your help.

I would like some information on this too, as it sometimes happens to me too

I'll just post some pictures up to demonstrate what I was talking about.
The second image is zoomed right in on one of corners of the hexagon. You can see what all those scratchy lines are comprised of.

I can't see your images, but I know what you're talking about. I have also had this issue in the past. If I remember correctly, the way I worked around this was to open the pdf in photoshop and then just do a SaveAs in pdf format and overwrite the existing file. The scratches were then gone. If you have Photoshop, give it a try and let me know if it works for you.

have you printed the pdf file?..i get this too but it prints the solid black just fine...

I'd suggest this too...I tend to notice some differences between what you see on your computer screen in preview mode in AutoCAD and also in PDF sheets before they're actually printed out.

For me, it wasn't the printed output that was the problem. It was the fact that I had to email the color pdf to a client for their review. I couldn't send something that had all those lines running through it. After saving it from Photoshop, the lines were gone.
