Elusive "Perfect Proof"

The CV system uses a supplemental set of 16 call-out colors which are blended at a stand-alone coating unit and applied to a WaterProof transfer sheet. The sheet is then sandwiched with the film separation and exposed under UV light. After washout, the sheet can be laminated to a carrier substrate, like a TV dinner carton stock or a polypropylene diaper bag. A separate sheet is subsequently applied for each printing ink being used in the job.
