Digital BW, The Print

IJM already sells K5 Pro inks for the ten ink printers. My hunch would be that they'd mix the warm and cool inks in the correct proportions so as to produce a neutral ink and then create the curves. I doubt that there's anything fundamentally new in what they're doing, they'd just be reshuffling their deck of cards to suit PK printing on six ink printers. IJM has always taken a different approach to Paul, in that they create neutral by adding toners to their inks to render them neutral, or some other toning effect, rather than by having a separate toner. I expect that practice would continue.
