Digital BW, The Print

Hello Eddie,

>Isn't it also true that the printer also uses a tiny bit of yellow 
>(or some other color and not just the K, LK, LLK)?

I can't say for certain about yellow.  Steve Karafyllakis just got a
3800 and made a PK "Black" print (a step wedge with ramp) on glossy
paper which I have here and am examining with a 6x loupe.  It's
definitely not a BO print.  I can see what looks like 3 different
shades of black and gray: there's a crossover point at 25% where LK
dots begin to come in on top of the LLK, and again at 55% where PK
dots begin to overlay the LK.

All I can see are gray and black dots, nothing that looks like color
dots (C, LC, M or LM).  However the dots are so tiny I suppose it's
possible that some yellow could be in there and hard to see, but it
doesn't look like it to me.  I doubt that Epson would call this option
"Black" and then put some color in there. Did you read this somewhere?

Regards,
Clayton
