🧠 SICHANGO Web Inspection System — China’s Leading Print Quality Control Solution

SICHANGO is one of the top web inspection system manufacturers in China, providing intelligent print inspection systems that detect even the smallest printing defects in real time. Our advanced inspection technology ensures 100% print quality control for flexographic, rotogravure, offset, and digital printing machines.

🔹 What Is a Web Inspection System?

A web inspection system is an intelligent camera-based solution that continuously monitors print quality during high-speed production. It captures stabilized, high-resolution images of fast-moving webs, helping operators identify defects such as:

• Color variation and shade mismatch

• Ink splashes, streaks, or ghosting

• Misregistration between color layers

• Missing text or barcode distortion

• Printing voids and surface contamination

SICHANGO systems integrate AI defect recognition, ACS panoramic scanning, and PPS print position storage — making them one of the most advanced quality inspection systems in the global printing industry.

🔹 SICHANGO Product Series & Technical Parameters

🔹 Key Functions: ACS Mode & PPS Function

ACS (Auto Capture Scanning) Mode

ACS mode automatically scans horizontally or vertically to generate a full panoramic image of the printed web.
Operators can view every detail of the printing layout, detect hidden defects, and save the panoramic image for offline analysis.

Use Cases:

• Complete image checking after setup

• Comparing entire print layout with the master sample

• High-precision color registration adjustment

PPS (Print Position Storage) Function

PPS saves print positions, ROI regions, and reference coordinates for each job.
When the same printing order is run again, the system automatically loads all parameters — no need for re-calibration.

Use Cases:

• Repeated printing jobs with identical artwork

• Multi-station printing machine changeovers

• Dual-camera synchronization

Benefits:

• Saves setup time

• Ensures consistent inspection results

• Reduces human error and waste
