Default scanning watermarks

hello all,
I'm trying to get a decent digital image of a watermark with my scanner.
My method is still not perfect although I manage to see the watermark but
not very clear. I'd appreciate very much if anyone could help me or
provide directions in achieving this goal in a better way.

Thanks,
pedro


Found in the RCSD archive but Pedro won't be able to read this answer due to

Hi,

After a little trial and error I've found a way to get nice JPG's of
watermarks.

1) Place the stamp face down on the bottom of a watermark tray (the smooth
side) and saturate with fluid.
2) Place the tray face up on the scanner.
3) Set the scan margins a little bit inside the borders of the stamp, so
none of the tray shows.
4) Scan at hi-res and manipulate the image as desired.

The images are very clear, although not as clear as in Scott, makes me
wonder if the wmk images they use are hand drawn or cleaned up somehow.

Anyone else do this?

What am I missing here? It looks like this will work only if the tray is
glass or at least transparent on the bottom. My watermark tray is all
black plastic.

Personally, I compare the watermark shown on the stamp in the tray with
the picture in the Scott catalog to determine what the catalog number
should be.
