Surface Inspection | BST eltromat International

Surface Inspection: 100% inspection in Real Time

Competition in the web processing industry is stiff, and the demands are constantly on the rise. Exact control of the qualities of the outer surface is a prerequisite for defect-free printing products – and for satisfied customers. Here, BST offers effective support with intelligent systems for 100% quality control during production.

Surface inspection systems provide information on the substrate’s outer surface quality, so that consistently high quality is guaranteed in the subsequent production steps.

BST Surface Inspection: Your Benefits

  • Uninterrupted quality control
  • Reliable defect detection
  • Fast defect correction
  • Increased productivity through automatic monitoring
  • Targeted defect prevention based on the analysis of production records
  • Reduction in waste and fewer returns
  • Increased customer satisfaction

Reliable Performance for the Surface Inspection

Our systems contribute to the first-class quality of your products, including through the following services:

Defect Detection in the Materials

Typical defects in the laminating and coating process (for example, gaps in the coating or delamination) are reliably and immediately recognized, shown to the user, and documented.

100% inspection

Due to their modular construction, BST systems can be perfectly adapted to the most diverse applications. A number of options, such as RGB or monochrome line cameras. Space-saving construction and easy, inexpensive integration. For perfect inspection results any time.

Defect Depiction

Image acquisition and defect detection in real time. Employable on uniform, textured, and printed outer surfaces. The automatic recognition and display of even the smallest defects and variations enables the user to make quick and secure decisions to avoid waste.

Defect Marking

A label inserter can be used for precise defect marking. If a defect occurs, the iPQ-Check surface triggers a label insertion at the position of the defect. The signal activation can be selected for the whole web or linked to specific lanes, and selected only for certain types and sizes of defects.

Roll Report

Overview of the roll and process quality and a list of individual defects in the entire roll. Documentation of changes in the system and parallel settings as well as the state of external signals (such as roll changes or problems). Creation of a report as the basis for the further workflow.

Defect Assessment

Fast evaluation of the roll report in accordance with valid quality criteria. Marking of individual defects or groups of defects as rejected or not relevant. Possibility of re-evaluation in accordance with changed inspection parameters. Usable at a central QA workplace or directly in the production.


Control of the rewinder with an exact stop at the position of the defect in order to fix the error. Time-saving winding with maximum speed between relevant defects. Generation of roll reports for delivery or the next processing steps.
