Digital BW, The Print

>I would suggest finding a printer that can print 10-20 micron 
stochastic screening(Hemlock comes to mind), and for black and white 
reproductions print tritones or quadtones. It's amazing what can be 
done by pushing a little metallic ink, bronze, gold, or silver down 
on one of the plates.<

I forwarded this to Focus Publishing. Here is his response:

"Straight Stochastic screening can yield interesting results in 
certain cases (bright, bold scenes) but not in others (subtle tones, 
flesh, etc).  It is also still an unstable screening due to the vast 
number of variables that can make a stochastic job great...or not so 
great. Brilliant Graphics' screening is a hybrid screen that utilizes 
a 300 line conventional screening over the broadest range of the 
scale.  However, where conventional screening can fall off the scale 
(upper hilights and lower shadows) BG's screening turns into 
stochastic – thus the name "Hybrid Screening."  This screening is an 
exclusive Heidelberg technology developed by Dr. Hell – the 
grandfather of scanning/digital screening. Focus Publishing not only 
offers you a higher quality printing than Hemlock and Dual Graphics, 
some of the few printers in the US that offer this printing service, 
but we do it for nearly half the price."
