No, but I've got a Kodak graycard and an i1 Pro. I don't remember how to create
.sp files, but, if you'd care to enlighten me, I'd be happy to oblige....
I've measured it in the past. It's a surprisingly good neutral target. The
spectrum is quite flat, and the Lab values are all within one unit of 50-0-0.
All in all, it's the best bang for the buck for gray balancing. It's amply
``good enough'' for everything but colorimetric accuracy...and, when you need
colorimetric accuracy, you need to be using a color-managed workflow in which
the gray balance is only used for the initial RAW conversion.
