Inline and Offline Printing Inspection Systems Empower Sichuan Xinhua Winshare to Ensure On-Time Textbook Delivery

Background

To ensure that all primary and secondary school students across Sichuan Province receive their textbooks before the new semester, Sichuan Xinhua Winshare Publishing & Media Co., Ltd. (hereinafter referred to as Xinhua Winshare) faced two major challenges: extremely tight production timelines and exceptionally high quality requirements.

Ahead of the 2025 autumn textbook season, after extensive research and on-site equipment trials, Xinhua Winshare highly recognized Beijing SINOMV Technology Co., Ltd. (SINOMV) for its comprehensive quality inspection solutions for publication printing. The two parties reached a strategic cooperation agreement, marking a significant step toward intelligent quality management in large-scale textbook production.

During this season, Xinhua Winshare introduced 43 sets of SINOMV’s inline and offline printing inspection systems to its subsidiary printing enterprises, establishing a province-wide intelligent quality assurance network for textbook and teaching material printing.

Challenges

Sichuan Province’s textbook printing task presented multiple challenges:

• Compressed production schedules, requiring continuous operation and rapid inspection turnaround.
• High quality standards, demanding zero-defect printing results.
• Automation needs, to reduce manual labor while maintaining consistent accuracy.

Traditional manual inspections could not meet these demands, prompting Xinhua Winshare to seek a high-speed, high-precision vision inspection solution.

Solution

SINOMV provided a comprehensive inspection solution combining offline precision inspection and inline real-time inspection, creating a dual-layer quality control system:

• Offline Printing Inspection System

  Equipped with dot-level detection precision, the offline printing inspection system focuses on first-sample inspection and random sampling. It can rapidly identify typical defects such as missing print, dot loss, smearing, and ink spots, preventing defective batches and ensuring the first line of quality defense before mass production.

• Inline Printing Inspection System

  The inline printing inspection system performs 100% real-time defect detection during printing, enabling immediate response to issues such as smudges, plate contamination, ghosting, show-through, holes, oil stains, and paper tears. This ensures stable quality even at high printing speeds.

  Together, the two systems establish a comprehensive mechanism of “offline precision detection + inline real-time monitoring,” enhancing both production efficiency and quality reliability.

Results

With SINOMV’s printing inspection systems in place, Xinhua Winshare achieved:

• Zero-defect textbook production across all contracted printing enterprises.
• Improved automation, reducing manual inspection workload and human error.
• Lower production costs through early defect prevention and reduced waste.
• Reliable fulfillment of the “textbooks before class” objective, meeting government delivery standards on schedule.

The collaboration also strengthened Xinhua Winshare’s leadership in educational printing within Sichuan Province and set a model for intelligent quality control across the publishing industry.

Conclusion

By integrating SINOMV’s inline and offline printing inspection systems, Xinhua Winshare built a high-efficiency, intelligent quality assurance framework that ensures precision, stability, and timeliness in textbook printing. This partnership not only safeguarded the province’s “textbooks before class” mission but also demonstrated the transformative power of AI-driven inspection in modern publication printing.
