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?
Thanks
