First, Introduction
Digital technology has revolutionized the entire printing industry, graphic communication, and even human life, living, mobility, communication, education, work, entertainment or other needs. One day, using digital technology to make "blind people visible" "It’s a sneak peek," and it’s no longer a luxury. For the printing industry, under the wave of digital changes, the three contents of text, graphics and images exist as digital files, and the words use the word files respectively. Taiwan uses Big 5 and 5 codes, and China uses GB GB code, Japanese has Wapro text code, etc. The graphics exist as vector diagram files, which exist in straight lines, semicircles, arcs and adjustable Bezier curves at each node. The image file basically still exists in dot matrix or compressed dot matrix. Although there are different formats and different ways of representing each pixel, basically the "entity" is used to form a line one by one, and the line and the line constitute an image frame. The principle is the same. Due to the development of DTP software, the editing of text, graphics and video into a page technology has long been used by many large design companies, personal studios, prepresses and printing houses. Due to the development of computer technology, it is possible to make a large version of the output of the sporadic page information file in full order. This can be used to manually scan the electronic image output image, complete the text and graphic files, copy it into a small version by hand collage, and then complete the large version of the collage according to the printing origami process. Not only do you not have to use a lot of manpower and materials, you can arrange each page according to the page order and layout in one step. The output is printed on the large sheet of negative film, and then the film is replaced with a high-sensitivity plate. The CTP computer directly prints the output, and the file with the digital information flow CIP 3/CIP 4 JDF is generated. This way, the prepress process has been greatly compressed, and it is more in line with the green demand of the printing industry for urban environmental protection and waste reduction. CTP plate making has no negatives, so the use of large-scale digital inkjet for proofing, the possibility of large-color poster output work, or the use of toner, electronic ink and other electronic imaging printers, can also do a small number of diverse production printing, mainly The creation of color stability and color management system is smoother and more perfect.
Second, inkjet printing
More than 40 years ago, the initial inkjet was only a very thick continuous pattern of 16 drops per ink, used in the wooden box, the outside of the carton spray, and now has reached 4880dpi is 300 times the original ink droplet diameter, The capacity of each drop of ink is only one-seventeenth of a million, about one-hundredth of the size of a 200-line dot. It has been difficult to see the dots on a photographic paper with a magnifying glass. Today, in large outdoor posters, large-sized interior posters, various propaganda, decorative and industrial inkjets, UV or Latex latex inkjets can be sprayed on most media, such as Riso's new DRHIS spray on paper. The ink machine, A4 150 sheets per minute, has a resolution of 600dpi, and the printing cost is relatively cheap, becoming the new favorite of the office and the tutoring class. The inkjet head can be used for local data printing on a printing press or a processing binding device to increase the added value of the variable data. Kodak's Versa Mark next-generation inkjet printer can print 300m per minute at 600dpi on 460mm wide format, which is equivalent to A4 2,400 pages, while Océ's high-speed inkjet also reaches A4 2,200 pages of color. Inkjet capability, HP's Web Jet Press dual engine achieves A4 2,600 pages per minute of printing capability, and the screen also has TP Jet 520 high-efficiency inkjet printers, which is currently the high productivity of toner printers. Moreover, these inkjet heads adopt wafer technology, and their speed and resolution process are rapidly developing as well as semiconductor technology. The multi-application of inkjet media, not only for visual functional printing, but also for industrial electronics, semiconductor technology manufacturing and material flow, can produce another level of application production.
Third, the electronic imaging printers contend
This is the full record of Mr. Carlson of Xerox Company. It was developed 70 years ago to charge and image the exposed and non-printed partial charge. The remaining charge can be used to adsorb carbon powder of different polarity to display. Transfer to the top of the printed paper. The previous photocopying was to neutralize the charge with the reflected light of the original light and shadow. Now, the laser light of the column is used to neutralize the charge of the non-printed portion of the OPC organic photoconductor, and it is changed from black and white monochrome to four. The imaging engine unit directly transfers CMYK four-color toner on the printing paper, or indirect toner transfer through the elastic transfer tape, which can prevent the OPC from being directly contacted by the printing paper. damage. Referring to color electronic imaging printing technology, the 1993 IPEX93 Birmingham Printing Machinery Exhibition in the UK is a new beginning, including the Belgian Xeikon color control DCPI with double-sided, ten OPC imaging ★ cartridges, the color toner printer in reel format Agfa also used the same engine to develop Chromapress, which is also a double-sided 5+5 printing method. In addition, Dr. Lander Dr. Lander invented an OPC imaging tube that can be printed once. , 4 colors of printing four colors, up to seven colors of P-1000 electronic ink printing machine, and there is blanket transfer, close to lithographic quality. The Indigo machine that has been acquired by HP today, after the 7000 model comes out, has reached a peak in quality and efficiency, and can be used for printing on roll-to-roll plastic materials, which is very advantageous in application. Xeikon to D-8000 efficiency reached a capacity of 220 pages per minute A4, but the increase is still limited.
Today, the digital printing equipment for toners is still the most widely recorded in the category of Fujitsu, and the latest generation of i Gen 4 in Zhangye, with 110 A4 printing capabilities per minute, and DC-8000AP and 5000AP high-end models. Fuji Full Record introduced the C 700 Japanese R&D toner digital printer, which passed the German Fogra color certification. In high-speed roll-to-roll color toner printers, the Xerox 490 is a stand-alone unit, and the X 980 is a two-machine combination that creates a front-to-back print. In the high-speed toner printing and the full recording is the German Océ Océ company, Color Stream 10000, is upgraded from monochrome, two-color, three-color CS-9600, using a double transfer belt system, A4 up to 800 per minute The printability of the page. Océ's sheet-fed digital printer CP 900 adopts the world's first seven-color hair coloring method, so the color toner does not overlap much. The green color is generally yellow 100+blue 100, plus some magenta and black, and CP-900 has only green ink. Add a little black ink and it will be OK! So the speed of A4 has 35 degrees per minute. All recorded and Océ have high-efficiency black and white roll-to-roll inkjet machines, which are faster than color. In addition to Fujifilm, Japanese color toner printers, such as Ricoh Ricoh, Canon, Konica Minolta, OKI, Toshiba, Olympus, etc., have a toner list machine with a maximum of 70-90 A4 printing capacity per minute, underneath There are 30, 40, 50, 60 and other speed toner printers, starting models from more than 300,000 yuan, 7 to 800,000 yuan, more than one million yuan and so on. If the high-end sheet of paper is from 600 to 25 million yuan, it will form a price-performance market with a very disproportionate capacity and price. If you buy a high-end color printer that prints 80 A4s per minute for 6 million yuan, why is the highest-end printer of the same brand, asking for more than 20 million yuan, 3.5 to 4 times the price, but the speed is increased from 80 to 110 minutes, the production capacity is only 40%. The manufacturer only said that the equipment of more than 20 million yuan is industrial grade, and it can resist 24 hours of operation without quality change, but unless the business is very stable, everyone will not dare to introduce such a good model, spend five or six hundred thousand. The purchase department buys 4 to 50 sheets of A4 per minute. The advanced machine is used first. It is not too late to go to the top and advance to the above. Anyway, the money left is still very good, and you have to wait until you understand it.
Fourth, the market first, equipment first
I believe that for those who are related to printing factories, output centers or other printing designs, from the concept of printing production, to the non-printing production market, we will temporarily lock the investment amount to more than 10 million yuan, otherwise it is difficult to calculate a buy one. Market and investment and return models for flagship devices such as i Gen 4 or HP Indigo P 7000. It is divided into several grades of machinery and equipment under 10 million yuan. The first is to look at the network capabilities, because in the future, these printing devices can only work within large companies or conference centers. In addition to the internal network system to print the workpiece content files, there may be prints from domestic and foreign networks. On the basis of this, there must be a certain bandwidth for Internet reception and transmission. Otherwise, it is unlikely to accept external files and lose business opportunities. The large-format printing device itself has a general capacity, and only depends on the bandwidth arrangement to have good transmission efficiency.
A lot of things are successful. Someone wants to start at a high speed and must lower their posture before they can have a high-speed starting momentum. It is too late to buy a machine and wait for customers, but it is too late because of modern equipment. The effective lead time will not exceed one year. Therefore, we must first study a level of familiarity. Only after 30% or 40% of the market has been introduced, and then add a little more, it is possible to reach the foundation of 50% or 60% to maintain the initial operation. Level, otherwise you can only reduce some of the money spent half of the time to buy advanced equipment, spend more time to produce, and then upgrade the business. And 15 A4 color laser listing machines per minute cost 400,000 and 4 million machines to buy only 60 capacity per minute, not 10 times the capacity to buy 20 million machines and only 110 per minute. It is not five times the capacity of 4 million yuan of equipment, so the gap is RIP interpretation and servo capability, more importantly, the price per print produced, the lowest order machine is five times higher than the high-end equipment, and the manufacturer also opened it. The market gap of equipment, otherwise buy five or ten advanced models, its production capacity is also large, and the purchase price of equipment is relatively low. If you have been waiting until the price/performance ratio is right, you want to get involved in buying equipment. Safety is safe enough, but you will often lose the market opportunity. So, while you are learning, don’t rush to invest too much money, just like Deng Xiaoping’s saying The method of the river must go forward according to the riverbed. If there is a depression, it will take a few steps to cross the past and maintain good physical strength. Many people want to go to the world in the print-free printing market. There are not many successful cases. Most of them are those who have basic work, such as bank and card issuing company's bill printing. One day, the network transmits POD to print on demand. This era is coming. After that, performance may have a chance to grow rapidly.
