Digital BW, The Print

Looking at a print made with the RIP thru a loupe reveals some photo 
(dark) cyan being used. This is corroborated by ink level movement --
 black the most, light black to a lesser extent and then photo cyan 
much less, but being used nontheless. If other colors are being used 
I can't pick it out. I accidently laid down a print made with the RIP 
next to an identical print made with Piezotone Selenium. When I came 
back into the room it took a little while to determine which print 
was which.
