Digital BW, The Print

Paul,....or anyone else who might know.

I mentioned before that i have tried the new PKN ink from mis
(printing b/o).The first cartridge exhibited a very,very slight 
banding(almost imperceptable(to me)on a vey dark print.The one i am 
using now,trying to print a lighter toned photo exhibits a huge 
amount of banding.The "dots" are much more noticiable also.All of 
this compared to a b/o print made with the epson ink,which is very 
warm.

I intend to take your(Paul's) suggestion about mixing mis pk and pkn 
to achieve a tone i like,but am hesitant to do so if i can't figure 
out how to "fix" the banding,etc with the mis inks i have tried.

Admittedly,i don't know much about chips,curves,profiles etc.Are the 
chips set differently?is the viscosity of the ink different?...any 
suggestions on how to "fix" this?

thanks,

andy graham
