Digital BW, The Print

All,
	Well, once again I tried to use the search engine to go through the 
archives, but came up with no results whatsoever.  What's up with it, 
anyway?
	So...I remember there being discussions of the various print sprays out 
there.  Print Shield comes up quite often, but also the Lascaux one.  I 
dimly recall that one works better with stuff like Smooth Pearl, while 
the other works best for matte stuff.  Can anyone refresh my memory?


thanks,
allan
