Maximizing print quality on corrugated packaging
Corrugated board packaging is considered to be particularly sustainable and is becoming increasingly important in the packaging industry. At the same time, the requirements for the design of displays such as shelf-ready trays, advertising displays or outer packaging made of corrugated board are increasing. Multi-colour printing with complex decorations in flexographic printing or small, possibly even personalized print series in digital printing processes challenge print shops to achieve the perfect quality of the printed image and at the same time reduce quality costs. With its inline print image inspection systems, ISRA VISION also offers you solutions for quality control in the various printing processes.
Flawless flexo printing
Discover the solution for print inspection on printed corrugated board using the flexographic printing process - CartonSTAR. The increasing demands on print quality are a key factor for a convincing shopping experience at the point of sale. Printing errors such as missing colors, inaccurate register, streaking, splatters, stains or faulty barcodes and QR codes can lead to waste and increase production costs.
Inspection begins with CartonSTAR even before the actual printing process starts. The future print image can be compared with a PDF file approved by the customer as early as the make-ready stage. In this way, errors such as incorrectly inserted or damaged printing plates become visible in advance and can be rectified before misprints occur.
However, the inspection of corrugated board poses further challenges, such as the detection of pseudo defects due to the uneven surface of the plates. Thanks to special algorithms, CartonSTAR detects these "false defects" and compensates for them.
During the printing process, the LiveSheetView function ensures that the operator can observe the printing process even more closely using precise live images. The print image currently being inspected is displayed on a separate monitor. It is possible to zoom in and out of the current image at various zoom levels in order to take a closer look at specific areas during ongoing production. The image size corresponds to the length of the print panel and the width of the material.
As a general rule, not every defect is a reject. Depending on the type or position of the defect, these can sometimes be tolerable. With defect classification, ISRA VISION offers a further function for checking the print quality and only displaying relevant defects.
For defective sheets, however, the finishing line is reached at the end of the printing process. Thanks to CartonSTAR, they are ejected and are therefore no longer part of the finishing process.

Digital printing
The demand for digitally printed corrugated board is constantly increasing. The big advantage of digital printing is the small batch sizes and the ability to personalize packaging more and more. This offers marketers many advantages for their campaigns. However, quality control is a decisive factor in keeping production costs stable, especially for small productions. In addition, digital printing processes are subject to special defects that are unique to this technology, such as streaking caused by clogged nozzles. For ISRA VISION, however, print image inspection is more than just the detection of nozzle streaks.
The inspection systems of the DigiSTAR series are specially designed for the detection of printing defects in digital printing. They check for all types of print defects: splashes or soiling, streaks, missing print image, color deviations and even detect defects that are difficult to see, such as banding. They also check the legibility of variable barcodes and QR codes.
The defect classification allows defects to be categorized as saleable goods or waste and also provides precise reporting on the defects found.
Whether you have your corrugated board printed using the sheet-fed or roll-to-roll process, there is a suitable system for every application.
The LiveSheet or LiveWebView function also shows the currently inspected panel on a separate monitor in digital printing and allows the operator to zoom in on specific areas.
In the roll-to-roll process, the ISRA systems are able to simultaneously inspect adjacent print images - so-called "panels" - of different lengths.
In the sheet-fed process, defective plates are ejected at the end of the printing process. In the roll-to-roll process, comprehensive reports and statistics provide information on defects, which can then be removed in downstream processes.
