Digital BW, The Print

Sorry to be so negative Paul but I used these regularly in large
format Epson machines for a couple of years. I would suggest you
cutting your loses and get out of there. The Lyson people have been
aware of this unacceptable metamerismic shift for many years. They
have served this monochrome community very poorly. They have also just
been bought out by some other company and who knows if they will even
offer these products at all. Hopefully not.
