Digital BW, The Print

Eric,

I'm using an X-Rite 810.  I just created two QTR profiles with PK ink at 60% & Black Boost at 70% and another profile at 60% again and Black Boost at 90%.  No excessive ink and the steps look "uniform" in both cases due to "shaping the curve" with a Gamma of 2.6.

Visually the 21st Step after of the 70% & 90% black look the same but measure 2.24 & 2.40. (As expected)

Will it make a difference in an actual print?...will need to try some prints.

Terry
