Digital BW, The Print

Paulo,

I just had an experience with the 7600 and the mixed k4/MIS Pro 
mixed inkset that might relevant and save you some trouble. I had 
mentioned earlier that I was using the M-Pro color; I am also using 
the K4 PK and LK; until recently I did not have a spectro and good 
profiling spftware, so I always assumed that the mediocre scanner-
based software I was using was responsible for the difficult and 
inconsistent profiles I was getting. When I got the Colorvision 
Printfix Pro package, I expected all that to go away, but while I 
got very good profiles for my R340 and R1800, the 7600 problem got 
much worse. MIS tech support tells me they also have never 
succesfully profiled a 7600 with the K4 inks in it, and that I 
should switch back to the MIS Pro PK and LK.  C.D. Tobie 
(Colorvision) tells me the density and blend zone for each inkset 
must be different enough that they don't overlap properly to produce 
a smooth ramp. IMHO you will probably have less headaches if you 
stick with a uniform inkset and work out a few custom curves where 
you need to, using QTR. If you're using the light inks for 
neutralizing, color dots won't be very visible anyway, except under 
high magnification. This problem may not affect you with the PKN-LKN 
you're thinking about, (or it might) but if you have trouble getting 
good color, keep it in mind.

Best Regards,

Steven Karafyllakis
