I use postscript to display diagrams which consist of small rectangles
of different colours (gray levels). When I print my diagrams on an
Apple laserwriterII, I find that the dots which make up the shading 
are too large, which makes the diagram hard to read. 

Is there an easy way to cause the setgray operator to use a finer screen
i.e. smaller dots in its shading?  Please mail replies to me.  I will 
post a summary if there is any demand.

Many thanks,
	Amnon Cohen
