The PQEye™ Print Quality Inspection Appliance Now Packs More Power

The PQEye is a compact (120 x 50 x 35 mm, without a lens), smart camera-based instrument that has been used to address narrow web print inspection tasks and check the position, correctness and quality of text and graphics machine-printed on discrete parts.
Formerly available at a maximum resolution of 782(H) x 582(V) pixels, systems can now be configured with resolutions of up to 1280(H) x 1024(V) pixels to provide reliable detection of defects smaller than those that could be identified by earlier models.  And this ability to resolve more subtle defects does not necessarily have to come at the expense of speed since it is now possible for PQEyes to be powered by Texas Instruments Digital Signal Processors that operate at 1GHz and supply computational power of 8000 MIPS.
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. The system’s setup, training and test procedures are all done using its multifunction keypad and a graphical user interface that displays on a standard SVGA or SXGA monitor.
Equally effective inspecting the results of offset, flexographic, thermal transfer, laser, and other common printing processes, the PQEye has been used to address many applications which were previously the domain of PC-based vision systems and proprietary "big-iron" boxes.
Typical high-end applications include the inspection of pharmaceutical product, food and consumer goods labels as well as integration into rewinders, cutting and slitting machines and high-speed bottle cap printing machines.  Typical low-end applications 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, pharmaceutical labels and cartons moving at slow speeds and printing on medical equipment and dosing devices.
User-friendly, easy to integrate, and economical, PQEyes provide very appealing levels of price/performance and enable companies to routinely achieve rapid returns on their investments.
