A Gracol G7 Certification provides outside credibility from industry experts that we maintain a high standard of excellence and quality.
Gracol G7 Certification
What is the G7 certification process?
Gracol G7 is a standard formulated by the Idea Alliance to form tighter controls for printing and proofing in the printing industry. The process for completion requires that the printer bring in a G7 certified expert for the entire evaluation process. The expert furnishes targets that are imaged to plate on a linear curve (the 50% dot must read ±1%). The target is printed at standard densities and is read and profiled (minimum of 6 press sheets randomly chosen in a run of 500 after densities are met). A curve is built, the target re-imaged and printed at standard density. Again, 6 random sheets are chosen for certification.
This process is repeated for every class of stock we use. All final sheets and G7 Kodak Matchprint proofs are evaluated and sent to RIT (Rochester Institute of Technology) where they are again read and evaluated for success. The evaluation includes the Heidelberg 74 and both web presses. In the past, we only evaluated one web press. This time we did base-lines from both presses to give us better spectral data for building the final press curve.
Why Gracol G7 Certification is Important…
To maintain a Gracol G7 Certification, you must go through the evaluation process on an annual basis.
