Digital Inkjet Printing Will Become A Major Trend

Now, digital inkjet printing The market is becoming more and more popular. Even many sellers sell digital printing as the key word of clothing products.

"Now the fashion cycle is shortened, and the pattern of flowers is changing. More and more consumers are pursuing unique fabric patterns." To meet the needs of the market, fabric developers have developed a large number of flower types. clothing Brand manufacturers provide choices, so that printing factories can make orders, reduce volume and increase variety. "

Traditional printing process costs the cost and time of making plate. Small batch orders increase the cost of fabric using traditional printing process and increase the difficulty of receiving orders. Digital inkjet printing is not only precise in color, but also natural and smooth in transition. Although it is more expensive than ordinary flat screen printing, it is worth the money to the fashionable consumers.

The popularity of digital printing is closely related to the popularity of fashion, digital inkjet printing. market It is also here.

Blow up industrialization "assembly"

For a long time, because of the high cost of digital inkjet printing, digital inkjet printing is only used as "printing proofing" in people's minds. This is a mistake in understanding.

"Some people think that the production of digital inkjet printing can not be as good as proofing, which is a misunderstanding." First, it can be determined that the production of digital inkjet printing can be as good as that of proofing. Secondly, there are many factors that affect the confirmation of digital printing proofing. According to the technical analysis, because of the different dye varieties and quantity, the color difference between the size and the sample will be different. If customers have samples, electronic documents or cloth samples, and whether the customers confirm them effectively, these are all obstacles to digital printing proofing.

For this reason, when digital printing is applied to proofing, it is necessary to deal with the "shape" and "color" of the image properly. It requires that the software of digital printing RIP (raster image processor) be upgraded constantly. It needs various technical conditions such as various color patterns, diverse output modes, different density curves and ICC (equipment color characteristics) files and abundant ink jet quality control parameters. That is to say, we can consider many problems that may arise in the process of mass production, and take some measures to simulate the effect of mass production according to the color separation map of large production. We use a complete digital printing card to establish different ink jet modes, and we need density curves and ICC files on different materials and different environmental conditions. At the same time, we must establish a standardized working mode to make the digital printing industry well.

Digital printing is gradually changing from sporadic production to agglomeration and industrialization. According to the insiders, more than 90% of the European printing industry has adopted digital printing proofing to achieve quick reaction production while keeping the environment clean. Europe's digital printing market share is so high that European textile companies are related to textile product design. The design drawings provided by European designers can often be applied directly to the digital printing equipment system, which is convenient for designers to put forward amendments to the proofing effect of digital printing and objectively promote the improvement of flower design level and the industrialization of digital printing.

Compared with the traditional printing process, digital printing has reached the height that traditional printing is difficult to achieve in terms of color, clarity and color gamut. However, many people in the industry are very sensible that in the next few years, digital printing will not replace the traditional printing process on a large scale. In other words, digital printing will coexist with traditional printing technology for a long time and complement each other. Digital printing has made up for the technical defects and blanks of the traditional printing industry, and has adapted to the international trend of the personalized printing market. According to industry forecasts, digital printing will account for 20%~30% of the printing market in the next few years. Compared with the current printing market, there is still much room for growth in the digital printing market. The domestic digital printing industry will also have a big development.

Digital printing technology is improving day by day

The origin of textile digital inkjet printing dates back to the 1975 Milliken-Millitron carpet printing machine. After that, digital printing technology has made great success in paper and film, which inspired people to promote the application of textile printing.

In 1991, on German ITMA, the fabric digital printing machine and printed fabric samples of the company Stork were displayed. In 1995, the reactive dye ink was displayed on ITMA, and the wide digital printing machine with the production capacity of 4.6m2/h and resolution 360~720dpi was unveiled. At the same time, the Japanese Seiren company used more than 200 Viscotecs digital printing machines to realize the industrialization of digital printing looms. This is a decisive step in the digital printing of fabrics.

At the ITMA exhibition in 2003, the Reggiani DreAM and Scitex Vision (Aprion) exhibited their cooperative DreAM digital printing machine, whose theoretical production speed was 150m2/h (35kHz). In addition, Aristri2020 (or lchinose2020) of DuPont Ink Jet and Japan's eastward industrial joint development has the highest production speed of 50m2/h. Today, the speed of the domestic high-speed series has risen from last year's 140m2/h to 180m2/h this year.

The rising star of domestic digital inkjet printing equipment has been focusing on the development of high speed digital inkjet printer. The ink jet printing method of digital printing is developed from continuous ink-jet to on-demand drip. Accordingly, two technologies, namely, hot bubble method and micro piezo electric method, are developed. Micro piezoelectric technology occupies an increasingly dominant position. Zhang Zhaofeng, marketing manager of the open source computer technology Co., Ltd. said: "digital printing is only part of the whole printed cloth production process, and it needs the matching of fabric pre-treatment and post-processing equipment to complete. As the pretreatment of digital printing fabric, drawing must be applied with necessary chemicals and dried into rolls. The post-processing of digital printing fabric is mainly fixation / steaming, washing, drying and coiling. The steaming equipment can be connected with the digital printing machine, shorten the process, and directly fix the color after printing, and can be adjusted into synchronous operation. The steaming equipment is not only suitable for fixing the acid, reactive and disperse dye ink, but also can be soft, white or flame retardant according to the market demand.

In addition, digital electrostatic printing technology has been developed in the United States and Japan. The image of digital inkjet printing fabric is formed by spraying the droplets onto the fabric by mechanical force (thermal bubble and micro piezoelectricity). The digital electrostatic printing fabric is formed by the cylinder surface of the optical conductor (usually selenium) and transferred to the fabric by electrostatic force, and its imaging speed is fast and productivity is high. Because digital electrostatic printing technology is still in its development stage, its maturity is temporarily unable to compare with digital inkjet printing. However, it has the following obvious advantages. Its production rate is 10~50 times higher than that of digital inkjet printing, the cost of coloring material is low, the printing depth is better, the image fineness and uniformity are better, the running rate and the defective rate are the same as that of digital inkjet printing.

In short, China's printing industry is in an important historical period of upgrading and transformation of industrial structure, and challenges and opportunities are parallel. Major changes in the field of textile printing will continue in 2011. It can be envisaged that the digital ink jet printing team will continue to grow, which is complementary to the traditional screen printing, resulting in the inevitable change of printing market structure and technological transformation.
