Digital BW, The Print

A quick look at the one week tone stability of what I'm calling the "4K+"
approach on my 7500 indicates the tones are very stable.  I overlaid graphs
of Lab A & B, matching the paper white and 100% black values to remove some
spectro variances, and the graphs were almost identical, particularly in the
highlights and midtones where a hue or tone change would be visually
detected.  This is far better than any blended inkset I've used in a large
format printer.

 

The current ink setup in my 7500 includes the 4 standard carbon inks:  MK
(Eboni), PK (MIS), LK (MIS), LLK (MIS).  The additional color inks to give
full tone control within the carbon to neutral range are as follows: LM
(Epson UC) & LC* (MIS; this is a special 50% LC for the old 7500).  A rip is
required; I'm now using IJC.  This concept will probably work well on other
6 and 7 ink printers.  On desktop units a variant of this setup appears to
have the best chance at full color management with profiling software.
