Defect Roll Map


PC Industries offers Defect Roll Mapping on the Guardian PQV 100% Print Quality Verification system. This flexible, reliable, and easy to use software is designed to help improve your bottom line by detecting defects (such as registration shift, color change, or missing periods) early in the process, allowing for corrective action, and providing a true count of defect free labels.

On Press
As part of a Guardian PQV installed on the press, the Defect Roll Mapping system records defects by lane and footage for each roll. The press operator can compare the print to the master on the fly, then accept, reject, or even train the system to bypass that defect in the future – all without stopping the press.

Editing workstation

Defect Roll Mapping offers an extra step of quality control (QC) between the press and the slitter/ rewinder. An Editing Workstation can be connected to any Guardian PQV Roll Mapping system. Information from the press run can be edited, and an operator can accept or flag defects before they reach the rewinder. The productivity of the slitter/rewinder is improved by eliminating unnecessary starts and stops.

Slitter/ Rewinder

The Defect Roll Map Workstation interfaces with the machine to locate defects on the roll automatically. The slitter/rewinder presents the defects at the splicing table and allows for the operator to take appropriate corrective action.

Defect Roll Mapping is flexible enough to be used on any press or rewinder, or as an independent workstation, and is one of several features we offer you to help you achieve defect free rolls.
