z Valco Melton – eliminates print defects
Valco Melton D4 & D16 Melters
Corrugated convertors ’ print quality expectations are rising over the world . The need to eliminate print defects from the production stream increases due to poor copies , cut sheets , registration issues , and general-flexo or digitally printed imperfections . PrintChek , a camera-based instrument for examining the entire width of every corrugated sheet , was created by Valco Melton ’ s ClearVision subsidiary for this purpose . The system , which may be mounted in either a flexo folder gluer or a die cutter , images , and analyses each sheet ’ s quality .
From smeared , ghosted , or missing print to inaccurate colors , spots , and hickeys , color registration issues , stripes , scratches , and spread , ghosted , or missing print PrintChek may compare each sheet to a standard , showing areas of concern that need to be deleted and examined . Along with defect identification , PrintChek inspects the sheet ’ s geometry for size , skew , and trim , as well as reading and evaluating barcodes for quality .
A low-profile camera module with numerous cameras positioned above ( topprint ) or below ( bottom-print ) the sheet , as well as light modules to illuminate the sheet , is the basic premise . As the sheet passes by , line-scanning cameras take photos , which are then reassembled to analyze . Defects as little as 2.0 mm
