Codpad chooses Xaar

Codpad, a Chinese company that produces inkjet coding and marking machines, has opted to use Xaar printheads as it looks to expand its product portfolio. Up to now, Codpad has specialised in CIJ and TIJ printers but is now branching out and exploring piezo printheads for a new range of printers.

The first of these printers is the P220 shown above, which uses Xaar’s Irix Pro heads with a UV-curable inkset. The main advantage is a high throw distance between the heads and the substrates and the ability to print to a wide range of substrates. This can run at up to 60mpm and will allow customers to print in different orientations including vertical printing. This series includes an option to use up to two printheads to achieve a wider print width.

The new machine, which was shown off at last month’s SWOP Packaging World Expo in Shanghai but is not yet listed on the company’s website, is designed for a wide range of coding applications including printing on metal, plastic, cartons, wood, aluminium foil, and films, which is the advantage of developing a system around UV-curable inks. The system includes a basic level of recirculation as well as temperature control in the ink supply though the Irix head itself does not have recirculation down to the nozzle level.

Xaar launched the Irix back in September 2021 as an evolution of its proven 128-series heads. It’s a bulk piezo head with a narrow print swathe of 17mm and 128 active nozzles, giving it a density of 185 nozzles per inch. It’s a compact lightweight head, measuring just 37.2 x 11.3 x 40.8mm and with a mass of 15.5g. 

Xaar offers both a Core version, for basic coding and marking applications, and a Pro version, which is targeted at higher value applications such as product printing and has a longer throw distance. CodPad has opted for the Irix Pro.

The Irix is available in two native drop sizes of 40 picolitre and 80 picolitres. Interestingly, Codpad has opted to use both variants to offer more flexibility to their customers who are looking at different requirements of ink laydown.

However, there is more to this story than just a single coding and marking machine as Codpad is already developing more printers that use other Xaar printhead models.

Xie Ruzhou, general manager of Codpad, commented: “The integration of the Xaar Irix into our high-resolution UV inkjet coding machines will elevate our product performance and market competitiveness and we are very confident that our latest product launch will offer our customers the superior coding solutions required to meet their evolving needs.”

Codpad, which is based in Guangdong, China, is a subsidiary of the Docod Precision Group and has specialised in coding and marking for over 20 years in the food, electronics, pharmaceuticals, plastics, construction materials and hardware markets.
