I've spent some time thinking about this and, thanks to BB's input, I've come up with the solution.

Previously I'd been trying to get the values of existing, known reference targets into Poser. While that might be doable, it would be insanely complicated.

The trick is to create an entirely new set of reference values that I can relatively easily define within Poser with absolute accuracy (to 6 decimal points, anyway). I have the tools to create an ICC-compliant reference target and a method of getting those into Poser. I've had limited time to test it but so far everything's worked as expected.

Next I'll be giving some thought to the design of the target: since we're starting from scratch, it seems logical to optimise it for Poser. Rather than the 24-patch ColorChecker (above) I'll go for something with more like 128 patches.

I'm going to find an easier way of inputting the values - Excel probably - than via the material room, because that would be truly tedious.
