Digital BW, The Print

I totally agree with what you said Bruce.

When it comes to Cone's NK7, the 7th channel is almost invisble and I
suspect put in there just to round out the total number of carts on
the new Epsons. There is no question that having a Hextone set
increases your tonality. The sixth channel is really really light and
definitely gives a smoother result than the quads. Before the K6 and
K7 inks came along recently, A guy out in California has been custom
diluting the older PiezoTone inks into 6 channels for some time with
outstanding results in regard to smooth transitions. 

I was sort of joking about trying the 12 channels of the new Canon
machines, but if you had those extra 6 spaces to play with and you had
a lot of time on your hands and a good rip that allows partitioning,
you could go to town with split toning arrangements. Some people a
year from now will undoubtedly engage in this. I think Cone is doing
it in a Roland now.
