Re: Followup on PowerRIP for the 2100/2200

2003-01-05 by carlislematthew2000 <carlislematthew@hot

I'm currently in the middle of tweaking my Gray Balancer curves to 
try and get neutral grays.  It's a pain in the ass and I must have 
got through about 30 pages of test prints so far!!  I keep 
adding/removing magenta, adding another control point, re-printing 
and so on.  I'm getting closer to a good result, but the closer I get 
the harder it is to do that final step.  

I don't have any PowerRIP, or RIP software, and actually don't know 
much about that stuff.  Am I really missing out?  Am I wasting my 
time screwing around with GB and printing ICM?

Also, how it is possible that you have no metamerism at all?  I 
thought the slight metamerism on the 2100/2200 was due to an inherent 
ink issue and not something that could be removed by tweaking?  Or is 
it the case that certain inks change color more than others and 
you've created a special ink-recipe that makes these effects cancel 
each other out in different lighting?  

As I write the printer churns out another test page from the GB 
software....  Any information, help or advice given is very 
gratefully received.

Thanks,

  Matthew
