GMG's ProofControl is Quality-Control System
ID number gives secure record of proofs
GMG's ProofControl quality-control system documents every proof with a specific identification number, giving print providers a secure customer record of approved proofs. The ProofControl system consists of ColorProof software (color engine, profile editor/creator, Fogra Media Wedge, and RIP), a GretagMacbeth spectrophotometer, and output modules for various printing devices.
Using the included spectrophotometer, the media wedge is measured and the resultant values are compared with stored target values. For all proofs within tolerance, a small adhesive label is printed on a label printer, which is also sold as part of the ProofControl system. The label, which contains all relevant production information, is then placed on the back of each calibrated proof. Every proof is therefore measured and marked as having met color standards.
