Zero defects with 100% automatic inspection of digital printing


Clogged nozzles during the printing process lead to nozzle streaks in the print image. CartonSTAR reliably detects them during inspection.

Efficient print control for corrugated board

Corrugated packaging is growing in popularity and has long been the proven shipping medium, even in demanding applications. Combined with the opportunities offered by digital printing, the recyclable material offers a variety of design options ranging from bespoke products to mass production. This printing process must also be of high quality. The upgraded version of ISRA VISION’s CartonSTAR 100% inspection system for corrugated cardboard printing image control can now also be used for digital printing.

Corrugated cardboard is traditionally printed using the flexographic process. This method of printing can be expensive to set up and is traditionally chosen for longer production runs. Due to the growing demand for personalized packaging and faster change, digital printing is becoming increasingly popular. The advantage is obvious: Since there is minimal set-up time in digital printing, smaller print quantities are possible – down to a batch size of one repeat. This gives digital printing a cost advantage, especially for small and medium runs, while ensuring very high print quality.

A flexible partner in digital printing
The CartonSTAR 100% inspection system for continuous quality and process monitoring can be used both in post-press and pre-press and is the ideal companion for digital printing thanks to its flexibility. The system is easy to integrate into the digital printing workflow and covers all requirements for an inspection solution as an intuitive and finely configurable solution. In addition to classic print defects such as registration accuracy, missing patterns or color deviations, CartonSTAR also identifies defects commonly found in digital printing, such as mottling, banding, streaking or streaking.

A particularly powerful and reliable function is the adjustable defect detection and classification thanks to the integrated compensation of the material surface. Known as a defect classifier, it quickly and accurately differentiates quality-relevant defects and irregularities caused by the uneven surface structure of corrugated cardboard, thus avoiding unnecessary waste. Instant recognition of defects allows the defective product to be rejected at an early stage, thus preventing further processing of defective sheets, thereby conserving resources and reducing costs in the production process.

Robust and reliable
CartonSTAR itself is very compact and is therefore easy to integrate into most presses. All ISRA components are extremely rugged and protected against heat, dust and high levels of humidity. In addition, the system can operate for years without any maintenance thanks to its highly efficient and long-lasting ISRA LED lighting. The condition monitoring function constantly observes all important system functions, thus avoiding unpleasant surprises.

With highly efficient 100% automatic inspection with CartonSTAR, companies can rest assured that only perfectly printed goods will leave their factory. Quality reports make every job traceable and give customers peace of mind while helping to prevent long-term defects and helping to get the perfect setup for the entire process. In addition, the solution reduces the amount of waste produced and facilitates more efficient use of resources, which, given the constantly rising prices of raw materials, reduces production costs.
