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?
Best regards
Claas

I have a question about proofing ISO 12647-2:2007 (or
Fogra 39).
The color of the print substrate used for proofing shall be in tolerance dE <= 3 with
the color of the print substrate used for production (for example according to Media Wedge
proofing process).
My question is: which document (and section) is this value of dE <= 3 specified?
12647-2 Table 1 specifies tolerance not in terms of dE but individually in terms of dL,
da, db.
There is perhaps another document or another section?
Can you help me?
Thank you.
Mauro Boscarol
