Yes, it actually narrowed the range by excluding sepia, but it gives better
control within the carbon to cool range.

I can't answer for Roy, but LK is not needed for the UT7 approach.  So, I
assume it was reserved for other inks or Glop.

It impacted almost everything.  LK is a basic input, and the supplier was
apparently shipping an LK that was too light.

The last sample of LK I received from MIS was fine.
