At K 2022, the company will present the Digiflex press, its first digital printing solution that enables the flexible packaging industry to meet the current needs of a changing and increasingly demanding market. The Digiflex will be the primary attraction at Comexi's booth 4B31, in Düsseldorf, Germany. From 19 to 26 October, during daily demonstrations, attendees will have the opportunity to view the Digiflex press in operation.

High quality requirements

"The Comexi Digiflex offers digital printing of variable data, such as Datamatrix variable codes, QR codes, barcodes, alphanumeric text, as well as other numbering and marking applications with high quality requirements," explains Pedro Jiménez, the digital technical sales director at Comexi, who also highlights that "it is a digital variable data print press that offers extremely high printing speed, superb quality results, as well as the highest level of performance and production. Digiflex is an all-in-one solution that includes the integration of the curing process, tension control, printing registration, corona treatment, and a video inspection system."

Comexi's new digital press uses low-migration inks that are suitable for food packaging printing; it is reported to offer excellent results in regard to quality tests (tape, ethanol, and scratch). The machine allows for the possibility of double-sided printing without treatment, as well as printing on pre-printed material. A digital press, the Digiflex is an efficient solution due to its ability to reduce set-up times. It can reach a maximum speed of 220m/min, reduce material waste, and improve lead time. Furthermore, the machine offers high printing quality with a resolution of up to 1200x1200 dpi, a minimum code size of 8x8mm, as well as printing and registration consistency.

Different codes with unique information

Using the Digiflex allows for the printing of variable data such as QR codes, DOT codes, alphanumeric text, variable information, numbering, barcodes, Datamatrix or images. Each printed code can be different and contain unique information, providing traceable material information, thus personalising products according to the consumer’s needs, and protecting brands from counterfeiting. "The Digiflex codes track and trace each product, complying with legal requirements as well as contributing to the circular economy, serialisation and security of the supply chain," says Jiménez, who emphasises that this machine not only "helps boost customer awareness, brand loyalty, and feedback acquisition, but also enables the analysis of consumer behaviour. Finally, the Digiflex offers security, anti-counterfeiting, and authenticity solutions, which is highly valued by brand owners.”

With its Digiflex press, Comexi participated in the R-Cycle project, led by the Reifenhäuser Group. The unique codes of the press identify the plastic type and performed production processes of each packaging unit, which makes recycling more appropriate and efficient.
