Label Inspection

Roll-to-sheet Inspection Machine

The variable data and print inspection rewinding machine of Daheng Imavision, is able to install on rewinding platform or printing production line, to perform offline and inline full-size inspection for rotary labels and plastic films. Industrial high-speed color camera is introduced to scan the label, inspect the printing defect and variable data. Alert when print defect, variable date defects of error, repetition, absence, bad code, etc are found.

Product Features

Two inspection modes:roll-to-roll,roll-to-sheet

Reject defective sheet, and good sheets collect by stacks

Algorithm can extract different color areas, and inspect each la yer automatically

Support sequence code, ink-jet code, related code inspection

System can store data and generate files by sheet
