In QTR Ink Calibration Help file there is this :
²The darkest ink limit will be called 100. Now match the density of the limit for the next lighter ink with the matching density of a percentage of darkest ink.
I don't quite understand what to do.
I have an Epson4000 with UT7 and I try to make an ICC profile with some glossy paper.
Here is what I did :
I printed the "ink pattern".
Reading this print I decided the ink limit to be 80 and SET it in the "ink calibration mode slider".
I made a new print and scanned it in B&;W mode, 16 bit and 300 dpi with no calibration and opened it in PS.
On the curve creator window, for the darkest ink, which is BK, I set "Gray ink", "Density" 90 that's what I found with the color sampler set to 5x5 for 100 on the ink pattern. Then for "Limit" I typed 100.
Then I am stuck here.
Is what I have done correct in the first place and then how to follow through ?
Anybody can help ?
Thanks
Michel
