Digital BW, The Print

Hi Daniel,

Thank you for the answer.

Yesterday a made a scan of the two printed 21-step-wide test pattern.
Then I scanned it and made an excel table with the average values of
each step. Printing a line graph together with an ideal linear one I 
verified that while the UT7/Roark/Epson curve is quite perfectly 
linear, my QTR ones have a different slope.

I'll follow your suggestion and linearize the QTR curve using my
flatbed scanner as a desitometer, hoping it has a linear output 
curve :o)

Ciao
Marco
