Re: gaussian blur?
If you scan it in RGB, most of the blue image will be on the R
channel, and the weave pattern will be mostly on the other 2
channels. Select the channel with the strongest weave pattern and use
Levels tool to make it much lighter or less contrast. Then convert
the mode to greyscale before saving it for insertion into PageMaker.
Of course you MIGHT be able simply use the R channel and discard the
other two channels to accomplish the same thing. It depends. You
could also tweak it before scanning, but that may be more difficult.
Please give it a try and let us know if it works.
