iPQ-Check Digital – 100% print inspection for digital printing

iPQ-Check Digital

iPQ-Check Digital from BST is a high-performance print inspection system for industrial digital printing. Based on the proven iPQ-Check for analog printing, iPQ-Check Digital offers additional advanced features for 100% print inspection. With short print jobs and changing jobs per track, PDF-based image comparison enables inspection from the first format and seamless switching between jobs. In conjunction with SMARTData, it ensures seamless workflow integration from prepress to postpress.

Description

In an industry where digital printing is characterized by high variability, frequent job changes, and small run sizes, the demand for flexibility is constantly increasing.

iPQ-Check Digital addresses precisely these challenges. Building on the proven technology of the analog iPQ-Check, this system is specially adapted to the needs of industrial medium and large-format digital printing presses. It offers 100% inline print inspection with full flexibility in terms of job length and job layout – perfect for everything from print runs of one.

The SMARTData interface seamlessly connects prepress, printing, and postpress. Jobs can be prepared digitally, automatically transferred to iPQ-Check Digital, and processed without manual intervention by the operator. Including automatic job changes and inspection from the first format.

Error classification also ensures that typical digital printing errors (e.g., print nozzle or print head defects) are reliably detected and documented. This combination of precision, flexibility, and automation means that iPQ-Check Digital improves your production in the long term.

What are your values?

  • 100% inline print inspection from the first format through PDF reference comparison
  • Full flexibility for short job lengths and variable job layouts
  • Short setup times and reduced human error through operator-free job setup, automatic job setup, and job changes
  • Detection of digital-specific defects through extended defect classification
  • Seamless SMARTData integration as part of a complete digital workflow from prepress to postpress

iPQ-Check Digital – your next-generation quality control: fully automated, highly flexible and seamlessly integrated
