I'm trying to print out large block letters in the background of some
linotronics artwork that will be taken to an offset printer for
reproduction.  I produced the tone originally at 10% in Adobe
Illustrator, which Ii believe produces Postscript output.  The tone
I'm trying to get in the final prints is approximately 10% or a little
lighter (8% - 10% would be fine).  I'm told that the postscript fill
value for 10% doesn't correspond to the printer's fill values, so, in
the brute force method, I have to go up to at least 20% to get the
tone picked up evenly.

Does anyone know what fill values I should use to approximate a printer's
values?  They seem to go in 5% increments.


Help!
