I have just bought a ColorMunki device to calibrate my monitor and printers. It is working fine. Anyway, I also want to help my friend by sending the 2 targets to him so he can print and send back to me to calibrate, but people said this won't work because the second target is normally the tuning from the first target, so sharing these targets for others to print won't be accurate.

I am asking if there is true, or we have other targets so we can share to friends and let them send the prints back by not need to go to their place and re-set up the software there?

I would be really appreciated all your help.
