[filmscanners] RE: Scanning for laser printing

["LAURIE SOLOMON" <laurie@advancenet.net>]

If the laser or LED is varied, which it might be, I would think it would be
to get differing degrees of saturation and intensity shades rather than
continuous tones.  These machines require 300 dpi inputs; but they apply all
kinds of porporietary dithering and the like as well as upsampling methods
to the output such that even at very large sizes the dot patterns are
relatively small and unnoticable except on lustre papers where they get
emphasized.

You may be correct about this Laurie.  I'll do some digging and see what
I can come up with.  Certainly, if the dots are small enough, it may be
unnecessary to vary the laser intensity.  It is much cheaper to make a
unit that is binary in nature when it comes to laser beams (on and off).
