Diana Eye 55 is an offline carton inspection machine designed for high-grade packaging quality control. Developed based on our inspection technology and manufacturing experience, it is used to detect printing and finishing defects on premium folding cartons and packaging products. The inspection system can identify defects such as hickeys, scratches, streaks, color variation, register deviation, substrate defects, hologram defects, and varnish inconsistencies.
