I suspect that Jim Perkins is correct that the grayish film and cast
shadows of ink lines are responsible for blurriness in scanning.
This happens in print, also.
A simple, non-digital solution is to spray the back of the film
(after completion of ink or any other media drawing; I do this with
carbon dust) with white paint. Any simple household white acrylic
will do - Krylon makes spray paints sold in hardware stores. Glossy
or matte does not matter, I think. Seems to me I have used matte, as
white as I can get. Tape down your film, upside down, so that spray
will not get on the front. Then spray gradually, moving the can back
and forth to slowly build layers until your image is invisible from
the back. Let the paint dry for a few hours. Voila! No cast
shadows and a white, velvety background.
