Analyze the application and market of inkjet printing in the printing industry

inkjet printing directly sprays the pictures and texts on the computer on the printing medium through the nozzle of the inkjet printer. Because it does not need to contact the printing medium, it can be free from any material restrictions, and can be used for high-precision color printing on the surfaces of coated paper, whiteboard, cardboard, sulfuric acid paper, film, self-adhesive paper, wallpaper, aluminum foil, imitation leather paper, ceramic chips, optical discs, acrylic, plexiglass, plate, leather, silica gel, plastic, PP, PE, PVC, cloth, stone, etc. And whether it is simple color block graphics and texts, full-color graphics and texts or graphics and texts with excessive colors, it can be printed at one time, without plate making, plate printing and chromatic registration. The color is beautiful, the effect is lifelike, the image is waterproof, sunscreen, wear-resistant, strong adhesion, no fading, simple machine operation and stable performance. At present, common inkjet printer brands include Epson, Canon and HP

in the printing industry, inkjet printing is also more and more widely used. On the one hand, as a supplement to traditional printing methods such as offset printing, silk screen printing, flexo printing, gravure printing, and even compete with some traditional printing methods, its application is mainly reflected in digital printing; On the other hand, it serves the traditional printing methods, and its application is mainly reflected in the digital proofing, blueprint proofing, plate making and printing of silk in the field of offset printing

digital printing refers to the direct printing of computer documents on paper, starting from one sheet, without the need for film and plate making. It can be taken immediately, with immediate error correction, variable printing, and on-demand printing. Compared with traditional offset printing, its advantages are mainly reflected in the following aspects:

one piece of printing, no film, etc. Traditional offset printing has fixed costs due to plate making, startup and other costs, which means that the printing cost of one print is very close to that of a thousand prints. The advantages of traditional offset printing are mainly reflected in mass printing. The unit cost of digital printing is the same. Its price and speed advantages can be reflected in the printing list of less than a few hundred copies

it can be printed at any time, and it can be printed as soon as it is changed. The traditional offset printing takes a relatively long time to start and debug, and the printing cost is high, and the operation is cumbersome. Digital printing, you can modify the text on the computer and print directly

it is suitable for printing on multiple media and can be taken immediately. Digital printing can be printed on coated paper, double offset paper, ordinary paper, photo paper, film, light box cloth, gold and silver foil, art cloth, and various special papers, which greatly improves the commercial application range of digital imaging. The business can cover photos, slides, pop posters, business cards, calendars, books, picture books, greeting cards, postcards, all kinds of cards, stereoscopic images, electronic photo albums and other fields

simple operation, convenient use, small floor area and low investment cost. Compared with offset printing equipment, inkjet printers cover a small area, are simple to operate, and are convenient to use and maintain. The investment of each equipment is about 100000 yuan. Usually, the price of the four-color offset press is in millions, or tens of millions of yuan. The captain of the offset press usually works for about 10000 yuan a month, requiring many people to operate the machine

digital printing has wider color gamut, bright colors and better gloss than traditional printing. Inkjet printing can print more than eight colors, with a wider color gamut, which can fully meet the requirements of users for color

digital printing, because it can meet the needs of rapid printing of prints, the development speed is quite fast, and the development space is very large. In the NAPL survey, when asked which service items you plan to add in the next two years, 48% of the respondents answered that digital printing services far exceed e-commerce and database management

in China, digital printing is also the development direction of the printing industry, and the market of exquisite color prints within hundreds of copies is growing. Bidding documents, annual reports, product specifications, enterprise profiles, recipes, etc. are all target markets. The pursuit of personalization has become a cultural trend, and the proportion of targeted print demand is getting higher and higher. Major enterprises such as insurance companies, real estate companies, banks and so on use a large number of personalized business letters, notes and other printed materials to win customers, while government departments at all levels and social groups' demand for personalized certificates is also increasing

variable data printing can be easily realized by using digital printing, and the image or text on each page can be continuously changed in one printing. Digital printing also plays an important role in anti-counterfeiting printing, which can print random color changing numbers, words or pictures, and provide various forms of anti-counterfeiting means. In addition, the web printing market is quietly emerging abroad. Any valuable document can be directly downloaded to inkjet printing equipment for on-demand printing without copyright, payment and logistics problems

inkjet printing can realize one printing without considering the printing volume in traditional printing. Because of this, inkjet digital proofing will also be well applied in the printing industry. In recent years, digital proofing has become one of the popular technologies in the prepress field of the printing industry. The so-called digital proofing is to output the data produced by the color desktop system directly through the inkjet printer without any form of simulation means, so as to check the image page quality of the prepress process, provide reference samples for the printing process, and provide users with the basis for signing and printing

this digital proofing technology does not simply print out color samples, but enables the output samples to reproduce the matching printing samples through complex color management software, including the matching and similarity of paper, ink and printability. Compared with traditional offset proofing, its characteristics are mainly reflected in the following aspects:

low investment cost and small floor area. Traditional proofing, imported monochrome proofing machines are more than 1million yuan, and the price of four-color proofing machines is about 5million yuan. The price of inkjet printer with digital proofing and four-color proofing or above is about 100000 yuan. It can use the same paper as traditional proofing. Although ink is still relatively expensive, the unit cost and total cost of proofing are still much lower

proofing is convenient and can be modified at any time. Digital proofing does not require film output, plate making and other processes, which not only greatly shortens the total cycle of prepress design, production and proofing, and saves a lot of raw materials, but also avoids the waste of man hours and materials caused by rework once a sample error is found after traditional proofing. The digital proofing system can output samples immediately after the original document is modified

the stability and consistency of sample output are high. Traditional offset proofing is greatly influenced by human factors. During the operation process, such as the pressure of the plate table, the pressure of the paper table, the height of the blanket and liner, the pressure of the water roller and the ink roller, as well as the temperature and humidity of the air, will affect the proofing effect. Digital proofing is hardly affected by the environment, equipment, technology and other aspects, let alone by the operator. Its stability and consistency are very ideal

fast proofing. Using large format and high-resolution inkjet printer for proofing, the time to output a full open sample is about 30 minutes, or even faster. For traditional proofing, generally, it takes about 2 hours for monochrome proofing machines to complete four-color large format proofing, which has not calculated the time that traditional proofing requires film output and plate making

high image resolution. The digital proofing system usually outputs frequency modulation points or continuous tone structure through inkjet printing. Therefore, as long as the output resolution is above 600dpi, the proofed sample can achieve the effect of amplitude modulation points of 150lpi. Now most color printers can achieve such image resolution. At present, the maximum output resolution of Epson inkjet printer can reach 2880dpi, and that of HP inkjet printer can reach 2400dpi

in response to the current market requirements for digital proofing, Epson launched 9880/9910/9450/9710 and other large format inkjet printers specifically for digital proofing, which have been greatly improved in speed, ink and media on the basis of the original 4-color series printer. HP has introduced a new concept of designjetz2100/z3100 large auxiliary surface inkjet printer, which improves the color management efficiency of waterproof coiled materials. Imageprogram8000/9000 launched by Canon adopts 12 color ink large color gamut technology, and uses up to 30720 nozzles to achieve high-precision printing

at the same time, the progress and development of the traditional printing industry itself, such as the application of CTP, eliminates the link of film output. In this way, the blueprint proofing in the traditional process can also be achieved through inkjet printing. Blueprint proofing is mainly used for proofreading the design and printing of graphics and texts, and does not have high requirements for color management. The traditional blueprint proofing process is more complex. First, the pictures and texts on the computer are output to the film, then the pictures and texts on the film are dried on the blue paper through the plate printer, and then developed through the fumigation of ammonia. Finally, the sun dried blue sample is obtained. The application of CTP saves the process of film output, which determines that the traditional blueprint proofing cannot be realized. For inkjet printing, it is easy to realize blueprint proofing. You can directly print the pictures and texts on the computer on plain paper or double offset paper to realize the effect of proofreading the pictures and texts. Moreover, without film and blue paper, the cost of digital proofing and blueprints is relatively low

in this way, the application of inkjet printing in blueprint proofing in the printing industry is closely related to the popularization and development of CTP, and has a bright future. Take a printing factory in Guangdong as an example. Eight years ago, the proportion of PS plate and CTP plate used by the factory was 10% to 90%, and now it is 90% to 10%. According to Bisheng article, a portal of the printing industry, the number of CTPs in China in 2007 increased by 136% over 2006, reaching 988. Compared with the same period in 2008, it increased by 146%. In 2009, it increased by 155% to 2249 sets. It is estimated that the number of CTP in the market will reach 3300 in 2010. According to the statistics of the printing association, there are more than 130000 printing enterprises across the country, which shows that CTP has great potential in the market. According to our visit to printing plants in Guangdong Province, for inkjet printing equipment used for digital proofing and blueprint proofing, generally small and medium-sized printing plants need more than two large-scale inkjet printers, and larger printing plants usually have more than ten printers

the application of inkjet printing in the field of silk printing is mainly reflected in plate making. First of all, for inkjet plate making, the piezoelectric inkjet printer is used as the output tool, the special inkjet plate making film is used as the output medium, together with the special inkjet plate making software, the software and the special inkjet plate making ink can output high-quality plate making film. Compared with the expensive laser Imagesetter, the cost of inkjet printer equipment is lower. In terms of using consumables, laser Phototypesetting films are expensive because of their photosensitive coating. Generally, domestic films are more than 30 yuan/square meter. The price of film for inkjet plate making is about 10 yuan/square meter. In addition, the laser phototypesetting film needs to be operated in the dark room, and the inkjet plate making can be printed in the bright room. At the same time, inkjet plate making can be output in large format, and there is no need to make up. Ink jet plate making film production, especially large format ink jet plate making, has gradually replaced the scheme of laser light discharge film with its own advantages, in sign printing, advertising printing, decorative plate printing, cloth printing
