Digital BW, The Print

David,

I'm not sure I'm following you. The Vivera inkset has a PK ( or MK), a Gray, and a light gray. All that would be needed is diluting that light gray roughly in half, and possibly also then in half again ( or 30% or so). If you used the same base HP uses what is keeping it from correct suspension? You are not mixing anything but the pigment and the base as a dilution. I have my doubts as to whether this would be applicable in an Epson head though, but that's not what I'm talking about.

And, what IS the base of Vivera? I can certainly find out if I ever end up with another used Z to play with.

John
