As of 2007, GRACoL Proofs are produced to the numbers. But if you feel the need for a visual reference, the GRACoL Visual Reference Kit can help you make the transition. You will choose a GRACoL #1 sheet produced by the manufacturer of your choice, certified to the numbers, to use as a visual reference proof.
Visual Reference Includes :
One (1) copy proof with visual images and ADS color bar
Selected from a batch of proofs that have been colorimetrically measured and certified by IDEAlliance to be within tight tolerances to provide a visual reference. Each proof is numbered, dated and bears the IDEAlliance Certified Proof seal.
Colorimetric data
Data from the ADS Proofing Bar on your proof, plus colorimetric data from measurements of the IT8.7/4 target.
