Re: [QuadtoneRIP] Re: linearization problems

2014-04-07 by Roy Harrington

The values are connected with a "smooth" curve. If the variations are too rough you
get swings that are too big (think Curves in Photoshop). The pre-linearized values have
to be good enough. Either tweak the values a little or adjust the curve for a better
approximation.

Reading the values into a spread-sheet and graphing them tends to show what's happening.

I am having the same issue with Lab values not linear. I did what you suggested and tweak them in order. Saved the.txt, when I when I put it in QTR linearize it gives the same non linear Lab values even though they are corrected. What should I do with the .txt file?
