Digital BW, The Print

No, I haven't compared to other inks. I was going to, but when I 
tested the Lyson inks, I was so pleased with the print quality, 
ease of use, and the ability to print without out all that fussing 
with curves/profiles etc. I just decided what was the point and 
have been printing away happily ever after. Of particular note, the 
Lyson won't clog your heads, and from what I've read from other 
users of MIS, the Lyson seems to have a richer deeper black, 
which can be a problem with the MIS.
Hope this answers your questions,
Don
