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 error-free printing products – and for satisfied customers. Here, BST eltromat 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 following production steps.

BST eltromat Surface Inspection: Your Benefits

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

Reliable Performance for the Surface Inspection

For the first-class quality of your products, our systems contribute to the following services, among other things:

Error Detection in the Materials

Typical errors 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 eltromat systems can be perfectly adapted to the most different applications. A number of options, such as RGB or monochrome line cameras. Space-saving construction and simple, inexpensive integration. For perfect inspection results any time.

Depiction of errors

Image acquisition and error recognition in real time. Employable on uniform, textured and printed outer surfaces. The automatic recognition and display of even the smallest errors and variations makes it possible for the user to make quick and secure decisions to avoid waste.

iPQ-Check Defect Marking

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 as well as selected only for certain defect types and sizes.

Roll Report

Overview of the roll and process quality as well as a list of individual errors 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.

Error Evaluation

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


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