QTR Curve modification

2005-04-28 by Richard Ayres

As I fine tune a curve for my 2200, I notice the curve for LK and LM drops off quite rapidly 
at about 90% on the 21 step grayscale, causing the 90%-100% steps to warm noticibly.  
How can the LM and LC curves be adjusted to the right to neutralize this warming?
