QTR-Quadtone RIP

Frank,

I was responding to Juan's inquiry, not yours, and your situation is 
really quite different.  If you are using Paul Roark's 3MK method 
with the 1800, that is totally different from Juan's situation, where 
he is using the Epson K3 inkset on a 2400.  Different print and 
different inks.  

I don't have an 1800 and haven't used the 3MK method, but I think I 
understand Paul's basic premise.  Since the 1800 lays down a very 
small dot (1.5PL, vs the 3.5 or 4 PL dot on the many other Epson 
printers) using the MK inks in three different positions can give 
smooth tones without the larger dots.  From what I have read, Paul 
uses three positions of MK inks for smoothness and he ramps the inks 
in at different rates.  And yes, the MK (or more accurately, the MIS 
Eboni Black) is quite neutral.  Paul is using the same exact Eboni 
Black in all three cartridges, and having three cartridges firing 
instead of one helps improve smoothness and avoids banding.  

Hope that helps.  

Lou

Glop. When I ordered some empty carts and 4oz of ink to refil them, I 
was told that one ink re-filled all three carts. Did I miss something 
someplace or is the LK and LLK used for a warmer town and what I 
bought was for just plain black and white. If it is for plain black 
and white, then why is the same ink used in three slots.

they work. I do know I get a very nice black and white using the 
epson inks and the QTR, better than using the Epson driver.
