Today, colour-accurate proofs have become an essential part of quality control in printing houses, and it is now impossible to imagine printing houses and agencies without them. A proof system that functions without problems and the manufacture of standard, colour-accurate proofs (“contract proofs”) is all the more important.
The ISO standard 12647-7 describes the test criteria for certifications of proof systems and proof production. All target values and tolerances are also described here.
print quality offers you assistance in the implementation of the standard for daily practice, as well as certifications in proof production.
