Re: Tips or techniques????

[Arthur Entlich <artistic-1@xxxxxxx>]

I have found that different flatbed scanners manage surface textures to 
different degrees.  One possibility might be to see if a friend has a 
different scanner to use that might diminish the problem.

Is you scanner using a CCD or CIS sensor system?  I think, in general 
CCD sensors are more apt to allow for ridding of the texture under the 
correct conditions.

You might also try to slightly raise the print off the glass.  On some 
scanners, this may be enough to change the lighting pattern, and 
eliminate the texture from appearing.  Make a small frame out of 
matboard slightly smaller than the edges of the print to create the 
space., and place another piece of mat board (preferably white surfaced 
on one side) over the print, so that the scanner lid doesn't press the 
print down in the center.  Flatbed scanners have different depth of 
field, so the amount the image can be raised over the glass will again 
depend on the scanner.

If all of this fails, you may be forced to photograph the print using 
either properly angled lighting or polarized light.
