High quality in metal sheet decoration at fast production speed

Metal sheet decoration is a complex process that places high demands on printing, coating, and material integrity. A whole range of defect sources, such as color deviations, printing defects, contaminations, edge defects, and material defects, can significantly impair the quality of the final product. One of the biggest challenges, however, is to achieve high product quality at a fast production speed. 

Our inline printing and coating inspection solutions ensure both 100% quality control and process optimization at maximum throughput.

Top-quality metal printing on steel and aluminum sheet

Reliable quality control for metal printing on steel and aluminum sheets is guaranteed by the DecoStar inline print inspection solution. The flexible system can be used for tinplate or aluminum as well as high-gloss or matte motifs on any type of machine. With highly efficient LED lighting, the system reliably identifies color deviations as well as edge and material defects. In addition, featuring an intuitive multi-touch user interface, the system delivers high-quality defect data that helps eliminate serial defects and reduce waste.

Flawless coating of metal sheets with automatic quality inspection

Coating and metal sheets

In the coating of metal sheets, reproductions due to unsaleable materials, low throughput, and high material waste lead to an increase in production costs. Therefore, only flawless-coated sheets may be processed in the printing press. Already in the raw material processing phase, our CoatSTAR inline inspection system detects defective plates and ensures that they are removed from production. Throughout the production process, CoatSTAR automatically records data on coating quality, plate edges, and weld areas. This data can then be further used either for internal process analyses or as proof of quality for the customer. CoatSTAR meets the highest quality standards and its modularity makes it suitable for any machine. 


100% inline inspection for every single sheet at the highest coating machine speed

Easy to operate. The intuitive setup procedure for new jobs or use of existing job files

Detection of defective sheets at the earliest possible stage of your metal decoration process

Coating inspection assures the best conditions for a later print run

Inline check of coating area uniformity

Reduce waste of raw material to a minimum

Advanced LED and line scan camera technology
