Corrugated board packaging is becoming increasingly popular and has been the proven shipping medium for a long time, even in demanding applications. When combined with the opportunities offered by digital printing, the recyclable material offers a variety of design options ranging from custom-made products to series production. This printing process is also expected to be of high quality. The enhanced version of Isra Vision’s CartonStar 100% inspection system for checking the print image on a corrugated board can now also be used for digital printing.
A corrugated board is traditionally printed using the flexographic procedure. This printing method can be expensive to set up and is traditionally chosen for longer production runs. Due to the growing demand for individualized packaging and quicker changeover, digital printing is becoming increasingly popular. The advantage is obvious, as digital printing has minimal make-ready, smaller print quantities are possible – right down to a batch size of one repeat. This gives digital printing a cost advantage for small and medium-sized print runs, in particular, while also 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 in both postpress and prepress 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 placed on an inspection solution as an intuitive and finely configurable solution. Alongside classic print defects such as register accuracy, missing motifs, or color deviations, CartonStar also identifies defects typically found in digital printing, such as mottling, banding, streaks, or smears.
A compelling and reliable feature is the adjustable detection and classification of defects through the integrated compensation of the material surface. Known as the defect classifier, this differentiates between quality-relevant defects and irregularities caused by the inhomogeneous surface structure of the corrugated board quickly and precisely, thereby preventing unnecessary waste. Instant defect-recognition enables defective products to be rejected early, preventing defective sheets from being processed further, thus conserving resources and saving costs in the production process.
Isra components are rugged and reliable
CartonStar itself is highly compact and is therefore easy to integrate into most presses. All Isra components are highly robust and protected against heat, dust, and high levels of humidity. Moreover, the system can run for years without any maintenance thanks to its highly efficient and durable Isra LED lighting. The condition monitoring feature observes all important system functions continuously, thereby preventing any unpleasant surprises.
Summary
Thanks to highly efficient, automatic 100% inspection with CartonStar, companies can rest assured that only perfectly printed goods will leave their facility. Quality reports make every single job traceable and give customers peace of mind while also helping prevent defects in the long term and assisting in achieving the ideal configuration for the entire process. Moreover, the solution reduces the amount of waste produced and facilitates the efficient use of resources, which lowers production costs by consistently rising prices of raw materials.
