As evidenced by these application examples, package printers have put web inspection systems to work for a broad spectrum of reasons, from meeting customer or end-use requirements, to establishing a general competitive advantage, to achieving process efficiencies. See for yourself.

Fast-forward for flexpack quality
A general push toward quality assurance has taken hold in the flexible packaging segment, reports Koby Shtaierman, vice president, marketing and sales for AVT. He hears more printer requests to see the web at all times, to provide process control and quality assurance for big-name brands such as Frito Lay and Coca Cola.
Flexible packaging converters who have recently invested in AVT equipment include Excelsior Packaging, which installed five of the company's PrintVision/9000NT units to enhance operating performance on PCMC, Uteco and Windmöeller & Hoelscher presses at its two packaging plants. Stevens Flexible Packaging put a PrintVision/ 9000NT unit to work with the purchase of a new Windmöeller & Hoelscher 10-color press. MainePoly looked to the PrintVision/9000NT to reduce waste and help run its presses faster for greater productivity.
Shtaierman credits the PrintVision Series' appeal to its "process control" workflow, or its ability to trace problems before they cause waste. The systems can potentially cut waste by more than half.
Custom connections
Elimination of costly and error-prone human inspection required to meet customer requirements led a high-end label printer to invest in PC Industries' Viper Printing Inspection System™.
The Viper automatically detects print defects, verifies the sequential human-readable characters via optical character recognition, and provides real-time measurement of critical print and die tolerances.
In this installation scenario, the system was required to interface to the label printer's existing equipment. Timed outputs were provided to stop the press, mark the defective product, and output the human readable characters via a serial interface. Customization without costly programming fees was facilitated with the system's drag-and-drop interface, which allows screen layout changes and features to be added without programming.
"We are finding more applications where it is cost-effective to replace or augment human inspection," states John Woolley, vice president of sales. "With increased demands being placed on printers, sophisticated technology is needed to meet higher quality standards and to maximize efficiency and profitability.."
Wider windows for strobes
Security, speed, and versatility are driving new installations of strobe inspection systems. A pharmaceutical printer has put Unilux's new Lith-o-Light (LOL) UV illumination kit to work inspecting the UV coating on a product which must have one area left coating-free for a printed serial number. The UV kit illuminates the coating to a purple haze, so that press operators can ensure proper application.
