Technologies & Techniques Master Image Verify Accuracy of entire Run With Defect Roll Map Press operators can stand confident that they can ship truly defect free rolls without sacrificing efficiency, knowing full well that they have verified press setup, registration and accuracy. Their self-assurance is further bolstered by the fact that they ’ve checked for missing, in- complete, or extra text; layout changes, bad barcodes, and defects within images. Some may find it surprising that the pressmen performed theses functions on-line, with the press running. The tool making this unprecedented efficiency possible: Guardian PQV with PDF Check. The system allows printers to perform true, 100 percent inspection against the original, customer- approved artwork. It can be engineered for almost any press or rewinder, ships as a single unit and once installed, has a small footprint that won’t waste valuable pressroom space. “At the beginning of a pressrun, the system captures an image of the first article off the press and verifies it against the customer approved PDF. The Guardian compares the documents with only a few clicks. Once the article passes in- spection, it is sent back to the press and becomes the master image against which the entire pressrun is verified,” accord- ing to its manufacturer, PC Industries.
