4.3.1.1
For the three gamut classes defined in 4.3.1.3, the print substrate colour shall be white with the colorimetric properties shown in Table 2. The print substrate used for proofing should be identical to that used for the production. If that is not possible the print substrate used for proofing shall be a close match to that used for the production in terms of colour, gloss, type of surface (such as paper, plastic, board) and mass per area.
NOTE If the final product is to be surface finished, this may severely affect the substrate colour.
