See if the material at p. 15 (or pp. 11 on) of http://www.paulroark.com/BW-Info/Eboni-4-Plus.pdf are helpful. The inkset doesn't make any difference. The basic procedures are the same.
QTR requires a minimum change in density or Lab L, and in the correct direction, before it'll accept the data.
Good luck.

hello all,
first time i'm posting, so I hope I get lucky with an answer.I have printed the 21 step white to black using (now print-tool, hence no color management), I clearly see that towards the darks, the last 4 or 5 pieces of the strip are very close to each other in visual.I read the L using spyder3, and I do get the values, and the curve is not linear at all.When I drop the values (as per the instructions) onto the the QTR linearization app I keep getting the same message can't linearize.So my question is, how do I linearize he curve then?ThanksMoises
