Introduction of Fuji Dimatix Head

Japan’s Fujifilm Fuji Dimatix (formerly Spectra in the United States) print head. The Spectra company first produced office printing thermal foaming print heads, and finally gave up due to the emergence of HP, and turned to research and development of industrial piezoelectric print heads, which were later acquired by Japan’s Fuji. The characteristics of its heads are that the ink droplets are small (high corresponding precision), the injection frequency is very high (fast speed), and the ink is not very “picky”. American Wit is the first brand to use Spectra nozzles, and it is also the most popular in the global market. A well-received inkjet printer, the problem with the Spectra is that the price of the printhead is too high. Although Wittur has sold hundreds of units in China, the inkjet printer products of several domestic manufacturers that use Spectra printheads have never become mainstream products, and they are mainly exported. It is a lightweight cartridge printhead with precision stainless steel packaging. All components can be moved quickly. It is suitable for printers with superior performance. There are four main models:

Among them, 128 series printheads have many similarities with XAAR128+ printheads in terms of stability and performance, while Nova256 series printheads are basically used by the printer manufacturer Wittech before the successful development of domestic inkjet printers. From the point of view of the internal structure of the print head, in the part of the print head that directly contacts the ink, the XAAR print head is made of Teflon material, and the Spectra print head is of steel structure. The ink has a certain corrosion ability. Due to the steel structure of the Spectra nozzle, the corrosion resistance of the nozzle to the ink is greatly improved first; the ink is pressed out of the nozzle, and the strong pressure can easily deform the diameter of the nozzle. The steel structure of the Spectra nozzle is higher than that of the XAAR nozzle. The inner coating of the material is more pressure-resistant. Therefore, Spectra heads have a longer service life than XAAR heads, changing the statement that nozzles are consumables. When it comes to the printing speed, the Spectra head has several times higher ignition frequency than the XAAR head, which greatly improves the printing speed of the inkjet printer. In the industry, the Spectra nozzle is a relatively high-end head.
