Quality Vision

"You might also have hickeys or ink spots that would appear in critical copy like dosage requirements," Leach adds. "Those kinds of things are absolutely critical in our industry."

Early detection

Completely integrated in the coating unit of the press, the inspection system incorporates two very high resolution cameras mounted in close proximity to the printing nip. During setup, the image of 25 sheets is captured to create a "golden image" to use as the digital reference file. Inspection Control provides automatic checking of the first sheet against the golden image and 100 percent inspection of every sheet during printing, and can identify defects as small as 0.3 mm. Upon completion of printing, it generates detailed reports that summarize and specify the number and the extent of any defects.
