Completely PC-free, the PQEye’s setup, training and test procedures are all done using its multifunction keypad and a graphical user interface that displays on standard SVGA monitors. Effectively inspecting the results of offset, flexographic, thermal transfer, laser, ink jet and other common printing processes, the PQEye is capable of addressing many of the applications which were previously the domains of PC-based vision systems and proprietary “big iron” boxes.

The PQEye’s inspection software features an automated training procedure during which all typical print variations are taken into account. This results in the setting of sensitivity levels that enable the system to reliably detect defects only a few pixels in size on media moving at up to 300 meters/minute, while still clearly differentiating between normal print variations and unacceptable print flaws. Inspection speeds can range from around three parts per second on individual items up to 20 frames per second in web applications, depending on the capabilities of the smart camera serving as the system’s implementation platform.

Typical high-end applications of the PQEye include: the inspection of pharmaceutical products, food and consumer goods labels, as well as integration into re-winders, cutting and slitting machines and high-speed bottle cap printing machines.

Typical low-end applications of the PQEye include: the inspection of pad or laser printed information on electronic components, keyboards, mobile phone and other kinds of keypads; printing and decorations on bottle caps; screenprinting on porcelain and glassware; lasermarked indicator/operator symbols on automobile dashboard panels; graphics and text marked on auto safety glass; pharmaceutical labels and cartons moving at slow speeds; and printing on medical equipment and dosing devices.
