Digital BW, The Print

Alex,

Why don't you send me a copy of the 100-step grayscale and I will put it in
the Files section.

Thanks,

the overall grey you are printing in a resolution finer than the 21 step
chart. I am having a quite challenging time working on a set of curves for a
2000P using the MIS FSe inkset. Flat spots in the curve are much more
visible in a real print than in that 21 step analysis. The graduated scales
in the PiezoTest print are also valuable to ensure there smooth transitions.
I think 8 bit i.e. 256 levels of grey ( 0.4 % steps ) are not your problem.
