Preface In the past 2001, in the field of inkjet printing in China, many domestic manufacturers continuously introduced the latest products and technologies. The wide application of these products and technologies has promoted the development of the inkjet industry in China. At the same time, as China joins the international trade organization, it also brings opportunities and challenges to the domestic inkjet industry. In the past year, in general, the domestic inkjet industry has exhibited the following new features:
First of all, each printer manufacturer is constantly making new innovations and using the latest inkjet products to seize this market. Hewlett-Packard Hewlett-Packard continues to occupy the leading position in the market with its "Hyper-Quality" all-round HP DesignJet5000 series large-format printers. In September 2001, HP launched the HP DesignJet10PS/20PS/50PS series A3 format digital design proofing machine. The new printer, together with the HP DesignJet1000, 800, 500 and other series of large format printers previously launched, has become the leader in the field of large-format color inkjet, occupying about 80% of the market share; the industry rival has just been Kodak and its own ENCAD, large-format inkjet and rookie Epson, as well as MIMAKI, Mutoh and other companies are also unwilling to fight for the market; and Saturn, Witt and Santec company because of its super-large inkjet display in the advertising industry. Therefore, the inkjet market is still in a situation of crowds and hegemony.
Secondly, the competition in the small inkjet field, which is about 1 meter in the inkjet market, is particularly fierce. The entire market can be said to be divided into two, with two areas of competition. First of all, inkjet product manufacturers have adopted drastic attack tactics both in market promotion and in product sales expansion, and their products have been continuously innovative. The form of competition has become increasingly fierce. Secondly, the inkjet printer manufacturers also put most of their energy in this area. They saw that in the inkjet family, this market has the largest share of cakes, so they are eager to split the market with knife and fork. Several family members.
Again, the inkjet market continues to grow substantially. According to a CCID survey, in 2000, China's printer market sold about 3 million printers, and its sales amounted to nearly 9 billion yuan. In 2001, the Chinese printer market sold 3.75 million sets of printers, with an annual growth rate of 21.9%. Among them, large-format inkjet printers have a large growth rate.
Finally, large-format inkjet printers are more widely used in various fields. The rapid development of modern society in the rapid growth of the application and demand for large-format color images, the increasingly high requirements for image processing, from black and white to color, from the output of bright and colorful images, to ensure the accuracy of color Sexual and reductive photo quality products, from low speed to high speed, whether it is colorful CAD, color accurate GIS, vivid color photography and art photography, colorful posters, advertising, posters, windows, or color reproduction In-place digital proofing, etc., large-format inkjet has a new vitality.
With the continuous improvement of the level of science and technology, inkjet technology has become more mature, with wider and wider webs, higher and higher precision, faster and faster speeds, more and more rich colors, increasingly better ink quality, and more consumables. The more common, the more convenient the operation, the lower and lower the cost, more and more practical, popular, the flourishing of the large-scale color inkjet is coming to us step by step, a bright fireworks is blooming inkjet sky.
Technology: Soul thermal inkjet printing technology for HP large format printers There are two main inkjet printing technologies: thermal inkjet technology and micro-piezoelectric technology. Most manufacturers use thermal inkjet technology, and a small number use micro-piezoelectric technology.
Thermal ink-jet printing technology was discovered by HP technicians in the 1970s, and the first thermal inkjet printer was invented in the laboratory in 1979. This technology has been adopted by HP, and HP technicians are constantly developing new technologies based on thermal inkjet printing technology. For example, color tiering technology and JetExpress technology are applied to HP products to continue to maintain Hewlett-Packard's leadership in the industry.
The thermal inkjet printer quickly heats the ink through a resistor. When the ink film is heated to about 340 degrees Celsius, a vapor bubble is formed and the ink is accurately ejected onto the paper.
The main characteristics of thermal ink jet printing technology · As TIJ technology work without mechanical movement, so with the rapid development of semiconductor integration technology, more nozzles can be integrated on each TIJ print head to achieve a higher nozzle density, this TIJ The increase in printing speed provides the technical basis. Microelectronics prints, due to the need for mechanical movement during the work process, can hardly increase the nozzle density, setting an insurmountable obstacle for increasing the print speed.
• Since there are the largest number of nozzles, there are spare nozzles as spare nozzles to ensure high printhead performance. For example, HP uses fault-tolerant printing technology.
· Since the TIJ itself is capable of inkjet printing by generating bubbles, entering the gas in the print head in a real-world environment will not have any effect on it. On the contrary, it can cause fatal damage to the micro piezoelectric print head.
With the rapid development of semiconductor technology, the nozzle density of TIJ's print heads is getting higher and higher, but the cost is getting lower and lower. In the HP modular ink system, the print head has become a long-life, low-cost, common Consumer products, users can replace the new print head according to the use of their own, long-term guarantee the high performance of the print head. Micro Piezo technology's print head, due to its high cost, has to be used as a permanent or semi-permanent component. With the passage of time, its performance will continue to decline. Once it is replaced, professional technicians will be required. Support, and the cost is also affordable for the average user.
JetExpress Technology
JetExpress technology is HP's further development on the basis of TIJ technology, and developed a rapid inkjet printing technology, which combines a high number of nozzles and high-frequency jet speed, the number of droplets ejected per second up to Thousands, to achieve a new breakthrough in inkjet printing speed, it is a technical foundation for the perfect combination of speed and image.
Its main features • On a 25 mm wide print head, the width of the cover for each stroke is 20 mm.
There are 512 holes in each color print head, and there are 3,572 holes in 6-color print heads, and in the market, printers using micro-piezoelectric technology have a total of less than 400 nozzles in 6 color print heads. On average, there are 60 nozzles per head, which is only one-tenth the number of nozzles on the print head using HP JetExpress technology.
· Spray frequency up to 30,000 times per second. Combining the smart chips on the print head, with so many nozzles and high jet frequencies, HP JetExpres technology print heads can quickly convert print data into print action, enabling fast inkjet print speeds.
Such as: Hewlett-Packard introduced the hp designjet 5000 series printer to print up to 52.86 square meters per hour.
Color layered printing technology Traditional inkjet printing technology mostly uses binary printing, that is, each ink dot on the paper has two ink droplets formed. When using four colors, black, blue, magenta, and yellow, each dot only There are 8 colors (black, cyan, magenta, yellow, red, green, blue, white). To express more image colors, the distribution of the eight color ink dots can be controlled by the halftone dithering algorithm according to the visual characteristics of the human eye, so that when viewed from a certain distance, a false blending color is generated and multiple types are realized. The performance of color.
With the development of TIJ technology, the HP TIJ printhead ejects droplets of a minimum size of 4PL. Based on this, HP introduced color grading technology. Different from the traditional binary printing method, the color layered printing technology can eject multiple drops of ink to the same ink dot, and each ink dot can have more than 200 colors. For a 6-color printer with color grading technology, such as the hp designjet 5000 series, the colors on each ink dot are more abundant. Using color grading technology, coupled with advanced halftone dithering algorithms, HP large format printers have now become the user's performance of tens of millions of colors, greatly enriching the color rendering capabilities of hp designjet large format printer users.
It can be seen that after adopting the color layering technology, the printer resolution is no longer the only standard to measure the printer's output color capability. Now the organic combination of the color layering technology and the resolution size can fully reflect the color performance of a device. ability. Color grading technology is another technology foundation that combines speed and image perfectly.
