Re: [Digital BW] Latest B&W inkset - HPR neutral curve

2006-02-08 by vmixer42

Paul,

Well, I'll pipe up and say this sounds REALLY COOL!  You indicated that you have this 
running in an R220 as more or less a testbed and mentioned the ability to have matte and 
photo black capabilities.  Does this apply to the R220 (or just to large format priinters as 
you originally mentioned)?  I run an R220 and would, of course, be very interested in a 
dual K solution for it (or really any affordable printer :).

Will this inkset become an obtainable product at some point?  I'd love to give it a try...  I'm 
having trouble committing to a certain level of warmth for, say, the life of an entire yellow 
cartridge since I'm still experimenting with different papers at this point.  Sounds like this 
would allow more fine-tuning for particular papers.

Anyway, sounds tres cool, thanks for all of your contributions.
