After using the Print Standard Verifier tool to check if the printing process of your organization conforms with the ISO 12647, the verification ends with a series of values that we will now explain.
Below you will see the ISO 12647 standard with its constraints. Benchmarked values and their ∆E are specifically defined for each standard. Globally, the controller will check the compliance of the printed control strip to the FOGRA39 dataset (coated paper) with rules and tolerances defined in the standard. CalderaRIP makes you print that particular control target while doing the print process check.
ISO 12647-2: Offset Simulation
This standard defines the quality of a CMYK offset printer with a heating system. It will allow you to reproduce an offset job on a digital printer, or to simulate the behavior of an ISO 12647-2 Offset press. This offset label is intended to do an informative print evaluation for simulating the behavior of an offset printer. Offset certifications shall always take place on real offset devices.

ISO 12647-2: Validation print
This standard defines the quality of a digital validation print process and the validation itself. It can be used to validate a print or a configuration print where the medium is independent.
