Description

Technical Field

[0001] This utility model relates to the field of paperboard inspection technology, and more specifically to an automatic paperboard printing quality inspection platform. Background Technology

[0002] After printing, some cardstock may have printing defects, such as smudges, missing prints, streaks, ink splatter, misregistration, incomplete hot stamping, wrinkles, scratches, uneven printing, missing varnish, and incomplete lamination. Cardstock with printing defects must be rejected.

[0003] Currently, paper cards with printing defects are removed by manual inspection. However, this method requires staff to stare at the paper cards for a long time, which can easily lead to fatigue and missed detections. Similarly, manually selecting defective paper cards is inefficient and time-consuming.

[0004] Therefore, developing an automated inspection platform for the printing quality of cardboard with high detection and screening efficiency is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
