The PQEye from The Value Engineering Alliance is a compact, 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. The 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 enables the system to detect defects only a
few pixels in size moving at up to 300 meters/min., while still differentiating
between normal print variations and unacceptable print flaws.
