Comexi to launch Digiflex

Comexi has announced a new digital printing solution for flexible packaging and labelling called the Digiflex, which mostly seems to be designed to print variable marking codes, either in their own right or in addition to graphics that have been printed on a flexo press.  

Comexi’s Digiflex is a monochrome inkjet device for printing variable data codes to packaging.

Consequently, the Digiflex only prints in black ink. The idea is that it will be able to print variable data, such as Datamatrix variable codes, QR codes, barcodes, alphanumeric text, as well as other numbering and marking applications with high quality requirements. It runs at up to 220mpm and offers resolution of up to 1200×1200 dpi, though the speed will be slower at this quality. It can print a minimum code size of 8×8 mm. 

The print modules are arranged on a rail and there appears to be space for up to 12 of them. Each module can print a 40.6mm wide line with 65mm between each line

It uses UV low-migration inks that are suitable for food packaging printing, and is said to have achieved good results with tape, ethanol, and scratch quality tests. 

The Digiflex is a complete machine that includes curing processes, tension control, printing registration, corona treatment, and a video inspection system. It’s possible to print double-sided without treatment, as well as printing on pre-printed material. It takes rolls up to 1320mm with a printable width of 1250mm. It takes materials from 12 to 200 microns thick, working with a range of substrates including paper, plastics and flexible films. 

Pedro Jiménez, the digital technical sales director at Comexi, commented: ”The Digiflex codes tracks and traces each product, complying with legal requirements as well as contributing to the circular economy, serialization and security of the supply chain.” 

It’s worth noting that Comexi first announced the DigiFlex back in April 2021 at a virtual Drupa event. At that point, it was conceived as an inline printbar that could be installed on flexo presses, laminators and slitters and able to run at up to 250mpm.

I would expect that Comexi is also working to develop a colour press that uses the same chassis, partly because this is an obvious thing to do to recoup the R&D investment. Plus, Comexi also announced a second press, the Comexi D4, at the same 2021 Virtual Drupa. This was designed to print to flexible packaging up to 760mm wide with water-based inks from Sun Chemical. At that time, the D4 was said to be configurable with a choice of four colours – CMYK – plus a further four – orange, green, violet and white. There would be a choice of high resolution running at 75mpm or lower resolution at 150mpm, using 1200 dpi resolution Fujifilm Dimatix printheads.
