Digital BW, The Print

Steadman, the toner is made of magenta and cyan, so it's a Blue toner, not a Cyan toner. Cyan is the most stable of the dyes used in color archival inks. Yellow was the problem.  Don't know about the tri tone question though

Also, the MIS variable tone inks lasted longer in a south window than any other inkset without any fading or shifting. The piezo inks turned brown/cyan faster than the same ink with the MIS colorant in it. THe blue inks make the mix even longer lasting, it looks like.
