The Value Engineering Alliance, a leading provider of machine vision systems, is adding an automated proofreading system, the Psifeye, to its array of application-specific systems.
Used to confirm that all product information documents conform to their designs with respect to both content and quality, Psifeye enables manufacturers to detect and correct errors early in their production processes, thereby preventing costly rework and product recalls.
Psifeye functions as a supply chain productivity tool from the beginning of document design through prepress, production and incoming inspection of printed documents.
Psifeye compares images of documents and plates scanned by standard large or regular format scanners. The proprietary image analysis software that powers Psifeye effectively deals with paper stretch, ink bleed-through and other printing distortions and effects universally identified as being primary causes of automated offline print inspection system errors. It also handles variations in electronic documents, enabling them to be compared to proofs, transparencies, plates, press sheets, inserts and outserts.
As comprehensive as it is capable, Psifeye inspects all aspects of documents, including text characters and symbols, graphics, chemical formulae, charts, and pictures. All differences that it identifies as exceeding user-specified size and contrast thresholds are located, marked, ranked and tabulated.
Psifeye does not completely replace human inspectors but, instead, enhances the speed and accuracy of the proofreading process by inspecting product hundreds of times more quickly than proofreaders and freeing them from the type of tedious, repetitive review work that routinely results in errors. The human operators of Psifeye systems are still the ultimate arbiters, because they review the internet-compatible (HTML) error reports that are generated, annotate them as required, initiate any appropriate corrective action and prepare the final reports for record keeping.
While the underlying AVIA (automated visual information analysis) technology has been proven effective inspecting security codebooks, surveillance photos, currency and stamps, casino playing cards, and flexible circuits, Psifeye targets and is used predominantly in the pharmaceutical and medical industries where the accuracy and quality of printed information are of the utmost importance.
