Ah yes, the question . . . . which I've gotten before. 

I'm using the transparencies to make photopolymer plates for intaglio 
printing on an etching press. There needs to be "grain" in the image, 
which will equate to "bite" on the plate, which holds the ink in the 
recesses of the plate. At higher resolutions you loose the grain and 
can't create a good plate for printing. Another option may be to 
add "film grain" to the image before, but I'm trying to keep it simple, 
if you can believe that! 

Best, David.
