PrintGuard Offline Pro - Offset Sheet Proof System (Flagship Edition)

This inspection system delivers pixel-level accuracy with PDF-based modeling for first-print checks, defect sampling, and color detection. One unit connects to multiple presses, offering a cost-effective alternative to manual inspection. Equipped with the self-developed P9 light source, it inspects diverse substrates from 20g–500g, including thin/thick paper, micro-flute, holographic, metallized, and embossed stocks. Suitable for books, cigarette packs, pharmaceutical packaging, and leaflets, it supports both sheet-fed and web-fed presses.

Product features

  • First Print Inspection: Uses PDF file templates to prevent mass waste caused by plate or printing errors.
  • Process Sampling: Models from printed samples to detect common printing defects such as ink spots, voids, streaks, oil marks, missing print, and registration deviations.
  • Client Mode: A single inspection system can be connected to multiple printing presses.
  • Optional Spectrophotometer: Enables measurement and analysis of spectrum, chromaticity, density, and dot percentage, providing ink reference values for each zone.
  • Color Evaluation: Based on the C9 standard, evaluates color consistency using both camera measurement and control strip analysis.

 FAQs

  • What is the difference between the Flagship Edition and the Standard Edition?

    image

    The Flagship Edition is a premium offline inspection system. In addition to the text and image defect detection functions available in the Standard Edition, it includes advanced color inspection. Equipped with a professional spectrophotometer, it performs high-precision measurements of color bars on printed sheets. The imaging system, motion platform, control system, and hardware configuration are also upgraded compared with the Standard Edition.

  • Is the detection speed of the Flagship Edition slower than the Standard Edition?

  • What information is included in the color measurement results, and how does it support print quality control?

    image

    The Flagship Edition scans the printed color bars along the sheet edge to measure CMYK color difference values for each ink key and monitor density variations across color patches. Results are displayed numerically, enabling operators to adjust ink levels quickly and maintain consistent color throughout production. It also provides color consistency evaluation and grading based on international standards (e.g., C9).

  • Can the color measurement results also be displayed on the client side?

    image

    Yes. In a one-to-many client setup, the client display can receive all inspection results from the proof system server, including color measurement data. Operators can reference the results directly at the press to make color proofing adjustments.
