iPQ-Check – 100% print inspection for flawless results

iPQ-Check

iPQ-Check is a high-performance inline print inspection system designed to ensure maximum quality and efficiency in print production. With comprehensive defect detection across the entire web width, it immediately identifies print errors, reduces waste, and increases productivity.
Its modular design, integration into the iPQ Center, and SMARTData integration make iPQ-Check a scalable, future-proof solution for sustainable production.

Description

BST iPQ-Check solves these challenges with 100% inline print inspection that monitors the entire web in real time. The print inspection system detects even the smallest defects in the print image right from the start of the process, allowing operators to take immediate corrective action. By utilising machine learning and intelligent error classification, the false positive rate is minimised as much as possible, and the focus is solely on the relevant errors. Suitable for all substrates – from paper to plastic films to aluminum – it delivers precise inspection and brilliant image results, even at web speeds up to 1,000 m/min. 

Minimizing operating effort and supporting the operator in his decisions across various process steps is the focus. Integration into the iPQ-Center (additional systems: iPQ-View and iPQ Spectral) enables defects to be avoided and setup times to be reduced through one time job setup for all systems, common user interface and intuitive operation.

Intuitive user interface and high-speed image processing simplify operation and ensure consistent quality. Numerous modules for expanding the print inspection system allow it to be adapted to your individual requirements.

Thanks to SMARTData integration, iPQ-Check fits seamlessly into your digital workflow. It automatically logs and evaluates inspection data, provides comprehensive quality documentation, and enables continuous process optimization.
