Well, I wasn't even going to /think/ of anything along those lines
until waaaay down the road...but a similar thought /had/ occurred
to me--that is, ``Wouldn't it be wonderful to have a test chart
optimized for black-and-white prints at the expense of color
prints?'' The idea was much the same as you describe: nothing but
neutral and near-neutral patches, but an entire chart filled with
them. Especially if it worked in an iterative manner like (I
assume...) the -c flag to targen does....
I'm delighted to learn that you're a step or several ahead of me.
Cheers,
