  • X-Y-θ Image Correction makes a stable inspection possible without an influence of feeding accuracy by correcting an image against sheet deviation or curved sheet caused by machine delivery.
  • Combination of high speed 3 CCD camera and high processing technology realized an accurate inspection.
  • Dedicated inspection circuit for barcode defect and picture auto-extract function make it possible to detect defects that you need to reject by arbitrary sensitivity setting such as weak level on base color, normal level on picture and strict level on barcode.
  • Color difference correction
