Digital BW, The Print

Austin,

Paul's test and posted results were done with all four MIS inks using his
curves and the Epson color driver in comparison to Piezo driver using all 4
Piezo inks. They are grayscale images printed as you would a photographic
image with 4 inks all in use. His tests meet the criteria you specified.
