Paper-based Formproofs are used in many packaging gravure sites to detect faults prior to engraving.
Furthermore in many cases a specially printed foil which shows the client approved data is compared against the Formproof.
DeltaProof 3.0 is an alternative soft proofing solution. Instead of making physical prints, DeltaProof visualizes the Formproof on a large 4k monitor. The client approved data is shown on the monitor as a “floating image“ on top. All checks that were done using the paper FormProof can thus be performed without actual prints.
