Nice work Carl, you got it exactly right. Have you tried going
directly from RGB to gray with the target, rather than through LAB? If
both are the same gamma it may work fine. I did it the LAB way, but am
wondering about the effects of the various methods of getting to gray
to print the target with our various output methods that want a single
channel file.
I've not discovered a way to get i1 photo to accept custom charts,
tried a number of things. If you come across something that works let
us know. Of course ProfileMaker will let you, but at a major cost.
Until then I think you are stuck with single patch reading, the charts
were designed with good color contrast from patch to patch so the
convert to monochrome probably confuses it at some patch borders.
Also, with ColorLab, you could design your own charts with patches in
colors that might be more helpful for accuracy with these particular
printing methods.
Cool,
Tyler
