Optimum throughput of saleable products when decorating metal sheets

  • Maximum throughput of high-quality products
  • Enhanced quality of metal sheet printing
  • Reduced waste and increased yield
  • High level of customer satisfaction

Top grade metal printing at maximum production speed

The printing of metal sheets is a complex process that places high demands on printing, coating and material integrity. A whole range of error sources, such as colour deviations, printing errors, impurities, edge defects and material defects, can significantly affect the quality of the end product. However, one of the biggest challenges is to achieve high product quality at a high production speed. 

Our solutions for inline print and coating inspection ensure both 100% quality control and process optimisation at maximum throughput. ISRA inspection systems are suitable for both offset and digital printing technology.

High-quality metal printing on steel and aluminium sheets

Reliable quality control for metal printing on steel and aluminium sheets is guaranteed by the DecoSTAR EVO inline print inspection solution. The flexible, easy-to-install system can be used for tinplate or aluminium as well as for high-gloss or matt motifs on any type of machine in both offset and digital printing. With highly efficient LED lighting, the system reliably identifies colour deviations as well as edge and material defects.

In addition, with its intuitive multi-touch user interface, the system provides high-quality defect data that helps to eliminate serial defects and increase yield.

Not every defect means a rejection:

Defect classification software makes it possible to differentiate between relevant and irrelevant defects and increases the saleable quantity. Thanks to the latest camera technology, the inspection systems offer maximum performance. A modern graphical user interface ensures a high level of user-friendliness.

Arkin increased process efficiency for flawlessly decorated metal packaging

Arkin, a Turkish manufacturer of metal packaging used for oil cans, food and non-food applications, increases print quality with a 100% inline inspection solution. The high speed of the printing press and the increasing number of colour applications made it difficult for ARKIN employees to monitor production and detect defects. ISRA VISION offered the perfect solution for this with DecoSTAR: the inspection system guarantees 100% inline inspection of up to 10,000 sheets per hour.

Flawless coating of metal sheets thanks to automatic quality control

Coating and metal sheets

When coating metal sheets, reproductions due to unsaleable materials, low throughput and high material waste lead to an increase in production costs. For this reason, only perfectly coated sheets may be processed in the printing press. Our CoatSTAR inline inspection system recognises faulty sheets as early as the raw material preparation stage and ensures that they are removed from production. Throughout the entire production process, CoatSTAR automatically records data on coating quality, dimensional accuracy and the quality of the weld seams. This data can then be used either for internal process analyses or as proof of quality for the customer. CoatSTAR fulfils the highest quality standards and is suitable for any machine thanks to its modularity.

Raising quality and productivity for coated and printed metal sheets

Cinbal - one of the largest manufacturers in South America - responds to the high cost pressure in the production of metal packaging with 100% inline inspection. The producer was faced with the difficulty that defects were not only occurring during the decoration process when printing, but also beforehand when coating the sheets. The CoatSTAR and DecoSTAR inline inspection systems offered a solution.

Production analytics - Data-driven production efficiency

The web-based production analytics platform allows you to check the system status of all production lines at a glance or analyze production data in detail. With the quality management system, you analyze historical data, monitor current inspection data in real-time, and identify future trends in your production process.

Optimization of production

Dashboards allow you to compare production line and product data onsite or remotely, providing key insights for optimization. This enables you to make informed professional decisions along your value chain to increase the product quality as well as profitability. You can continuously track the progress of optimization measures and present them with visualized advanced reports.

Early detection of production defects

Detect and quickly identify the cause of threshold value violations at every stage of production with live status information and automatic alerts. As a result you can quickly resolve production defects, shorten downtime, and reduce production costs.

Predictive maintenance

You can prevent potential system failures by analyzing real-time data from the sensors and monitoring systems. This allows proactive planning of maintenance, based on the actual condition of the machines, instead of following a fixed schedule.
