Re: [NTLK] Question About Scanning

In scanning thin paper, some of the light from the illuminator will
pass through the paper and reflect off the backing surface, then pass
back through the paper picking up whatever image or text is on the
backside before impinging on the detector. You can avoid this problem
by making the backing black or otherwise non-reflective.
