Dear Mauro, all,
ISO 12647-7 is the standard that states proofing requirements today.
There you can find (section 4.2.1) general requirements for a proofing substrate.
The tolerance for the simulation of the production stock's white point is stated in
Table 2.
Hope that's what you are looking for?
Yes, that's what I wanted.
Thanks to you and everyone else who responded.
Best regards.
Mauro
