Real-Time Shade Variation Detection for Rotogravure Presses

In the highly competitive packaging and printing industry, even the slightest shade variation or misregistration during rotogravure printing can result in rejected jobs, wasted material, and serious financial losses. The SICHANGO OVERSEER 200 is specifically engineered as an automatic web inspection system for rotogravure printing machines, helping businesses eliminate such risks through advanced real-time defect detection.

Why Shade Mismatch Is a Hidden Cost in Rotogravure Printing

Shade mismatches are often overlooked by human operators during long print runs. These subtle color variations may go unnoticed at first but become highly visible in the final packaged product — compromising brand consistency and customer trust.

Our clients report significant losses due to:

• Unnoticed tone mismatches across print batches

• Manual inspection errors

• Delayed defect detection during high-speed jobs

SICHANGO OVERSEER 200 solves this with high-precision AI-powered print monitoring.
