On-Line Printing Quality Inspection-On-line Printing Quality Inspection System-Shanghai Zeyi Intelligent Technology Co., Ltd

Product Application Scope

Suitable for single-sheet printed products after die-cutting, and applicable to printing quality defect inspection of paper packages such as clothing hang tags, pharmaceutical packages, electronic products, daily chemical products and color boxes.

Product Features

Full-item Real-time Inspection: Able to identify various continuous printing defects including graphic deviation, color difference, misregistration and missing print; trigger audible and visual alarms synchronously to remind staff to adjust production timely, effectively reducing reject rate and production cost.

High-speed On-line Monitoring: Maximum inspection speed up to 300 m/min, real-time monitoring of production line status throughout the process, suitable for high-speed production scenarios.

Efficient Rapid Modeling: Support rapid modeling to simplify operation procedures and greatly improve overall production efficiency.

Visual Defect Management: Display and save defect data in real time for later sorting and rejection of defective products; all inspection records are stored in a unified database, which can be queried, statistically analyzed at any time via the defect management system, and generate reports with one click to provide reliable data support for quality control.

Product Advantages

Intelligent System Linkage: Connectable to MES system to record production scheduling data automatically; inspection results are stored in cloud, enabling managers to grasp production progress anytime and anywhere.

High-definition Imaging Recognition: Adopt brand-new imaging solution to capture all types of flaws, realize full-process defect tracking and avoid missing continuous defects.

Intelligent Rapid Modeling: Complete intelligent modeling within only 2 minutes; support automatic product capture, position calibration, text and QR code recognition with high automation degree.

High-precision Inspection Algorithm: Equipped with professional algorithms to realize accurate detection of ink dragging and text at 0.10 mm level.

User-friendly Operation Experience: Support multi-magnification defect zoom view and visual modeling selection; equipped with flat interactive interface for simple and intuitive operation.
