QTR-Quadtone RIP

Mike, I'm using the 9900 for MK and PK color, but in 6 channel color mode rather than RGB, therefore the K channel problems reveal themselves more visibly than the OEM driver which scrambles the dot sizes and light inks far differently.
Also, for PK B&W work I use it much like QTR users would, K, LK, LK2, plus small amounts of color to suit. Even for MK mono work like Strong sepia that needs more hue than the Cone inks. Those setups require good K channel performance and revealed this problem quickly.
The 9880 has Cone inks in it for M B&W and working beautifully.
