Sure. I am acquainted with those solutions. But I was wondering more
custom media wedge, one that can be tailor-made, independently of any
particular RIP software package. Is there any resource that you know
deals with how to put together and verify this custom media wedge for
different print scenarios?
Taking the scenario there is not much left what patches should be used.
You are judging how good a proof system simulates a given (standard)
1) (How correct) does your proofer represent the gamut boundaries
of the simulated process?
Take the primary colors (CMY), the secondary colors (RGB), black and
of your simulated process.
2) Does your proofer simulate tonal value increase correctly?
Take the values of 40% or 50% patches of your printing process.
If you want it more correctly, also take 10% and 90% or as much
as you want to spend time to measure it.
3) What about simulating the grey balance of the printing process?
Add step wedges for CMY and K.
4) How does the proofer behave simulating critical colors?
Add patches for flesh tones, colors that are often in nature objects,
dark, nearly unsaturated colors, colors that could show metamerism.
5) Find a good compromise between the number of patches
(the operator is willing to measure every time), the size it
occupies on the proof, the demand that you don't have to
cut it out to measure it, and of course accuracy.

This is what the FOGRA mediawedge does:
