First, digital jet printing technology
Digital jet printing technology is the development and application of the integration of printing and dyeing technology and information science and technology. Digital jet printing technology relies on three major technologies of information technology (1) computer aided design (cad) technology; (2) digital manufacturing technology; (3) computer network technology. The use of these three technologies to digitize the entire processing technology of the printing product, so that the entire production process of the printing is digitized. Therefore, the new production mode can be used to improve production efficiency, improve product quality, and greatly reduce environmental pollution, so that printing technology enters a new era.
The digital jet printing machine is the latest printing equipment that appeared in the international market in the 1990s. It is another brand new printing method after the embossing printing, flat screen printing, roller printing, rotary screen printing and transfer printing. It is a traditional printing. A major breakthrough in technology.
Second, the principle of digital jet printing technology
Digital jet printing system is a high-tech product integrating mechanical, electronic and information processing equipment. It is a brand new digital printing and dyeing digital technology widely used in international textiles.
Digital jet printing is a digital image transmitted by various digital input means such as scanners, digital cameras or the Internet. The required pattern is input into the computer, edited by a computerized color separation system (cad), and then controlled by a dedicated software driver chip. The printing system directly prints special dyes (such as dyes such as active or dispersed) onto a variety of fabrics or other media to obtain the fine print products required. The digital printing technology has got rid of the round-trip conversion process between the digital and analog quantities of the original printing color separation, production and web production.
Digital jetting technology creates an individual color point by applying an external force to the dye solution to spray the dye solution through the nozzle onto the fabric. Digital jet or digital jet is a jetting technique of digital image technology. Digital technology controls the jetting and non-spraying of the nozzle and the movement in the xy direction to form a corresponding accurate image on the printed medium.
For digital jet printing, since the entire image is composed of fine color dots, a higher jet dot density is required. The jet density refers to how many dots per inch (dot per inch), which is usually used. An important indicator for measuring inkjet printers. Generally speaking, the 180-360 dpi resolution of the text can satisfy the printing resolution. For images, the aesthetics of sharpness is generally achieved at 360 to 720 dpi. The printed fabric is limited by the warp and weft density, and the resolution is not as high as possible. (1440dpi has no point status). After the resolution is improved, the nozzle injection frequency and positioning accuracy are put forward higher requirements. Digital jet printing The machine is the product of the advanced stage of digital jet technology, which requires high-precision nozzle technology, high-precision mechanical control technology, high stability, reliability and corresponding jet dyeing.
Third, the experience of digital jet printing technology in practical production applications
The application of digital jet printing technology is truly reflected in the market demand for individualized, small batch and fast response. Change into a single variety; change the plane to three-dimensional; change the decoration to practical. The production form is flexible, the design is enriched, and the application method is personalized. Greatly satisfy the modern consumer psychology of seeking newness, seeking differences, seeking change, and seeking individualization. At the same time, the most fashionable high-tech, green, energy-saving, water-saving and other terms are interpreted.
