An analysis of the types and investment of digital printing

I. preface

digital technology has brought earth shaking changes to the entire printing industry, graphic communication, and even the very narrow channels of human life, daily life, action, communication, education, work, entertainment, or other needs. One day, using digital technology to make "blind people see" and "deaf people hear", is no longer a luxury. For the printing industry, under the waves of digital changes, text, graphics and images exist in digital files, texts in their own code files, big five codes in Taiwan, GB national standard codes in China, wapro text codes in Japanese, etc. graphics exist in the form of vector graphics files, and exist in straight lines, semicircles, arcs and adjustable Bezier curves at all nodes. Image files basically still exist as dot matrix files or compressed dot matrix files. Although there are different formats and different ways to represent each pixel, they basically form lines with "entities" point by point, and the principle of forming image images with lines is the same. With the development of DTP software, text, graphics and image have become a page technology, which has been used by many large design companies, personal studios, prepress and printing plants. Due to the development of computer science and technology, it is possible to make a complete combination of sporadic page information files and make a large version output in page order. This can make the previously complicated process of first scanning and outputting images and taking photos to complete text and graphic files, then copying them into small versions by manual collage, and then completing the large version collage by printing and origami process. Now, not only does it not need to consume a lot of manpower and materials, it can accurately arrange each page in page order and layout in one step, and output them on the large print negative, Further, the negatives are replaced with high-sensitivity plates, that is, now CTP computers directly print plates, and files with digital information process CIP 3/cip 4 JDF are generated. This has greatly compressed the prepress process all the way, 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 it is possible to use large-scale digital inkjet proofing to derive the possibility of large-scale poster output operations, or use electronic imaging printers such as toner and electronic ink, and it can also be used for a small number of digital diversified production and printing, mainly in the establishment of color stability and color management system

II. Inkjet printing

more than 40 years ago, the initial inkjet was only 16 drops per inch. Domestic instruments lacked a special solution developed for the object of use. The thick dot continuous type, which is used outside wooden boxes and cartons, has reached 4880dpi, which is one 300% of the direct diameter of the original ink drop, and the capacity of each drop of ink is only one 27million, about one percent of the size of 200 line points, It is difficult to see ink spots on the photo paper with a magnifying glass. Today, in large outdoor posters, large indoor posters, and inkjet for various publicity, decoration and industrial purposes, UV or latex inkjet used can be sprayed on most media. On paper, such as Riso's drhis new inkjet machine, A4 150 sheets per minute, with 600dpi resolution, printing cost is relatively cheap, and has become a new favorite of offices and cram schools. The inkjet head can be used for local data printing on the printing machine or processing and binding equipment to increase the added value of variable data. The new generation of Kodak's versa mark inkjet printer can print 300 meters per minute on 460mm wide paper at 600dpi, which is equivalent to the capacity of A4 2400 pages, while OC's high-speed inkjet machine also has the color inkjet capacity of A4 2200 pages, HP's Web jet press dual engine has the printing capacity of A4 2600 pages per minute, and the screen also has TP jet 520 high-efficiency inkjet printer, which is a high productivity unmatched by current toner printers. Moreover, these inkjet heads adopt wafer technology, and their speed and resolution process are developing rapidly as semiconductor technology. Ink jet media have multiple applications, not only for visual functional printing, but also for some industrial electronics, semiconductor technology manufacturing and material distribution, which can produce another level of application production mode

III. hundred schools of thought contend for electronic imaging printers

this was developed by Mr. Carlson of Xerox company 70 years ago. It uses charged imaging to neutralize the non image part charge after exposure, and the left charge can absorb carbon powder of different polarity to develop, and then transfer it to the printed paper. In the past, photocopying used the reflected light of the light and shadow of the original to neutralize the charge. Now, laser light and a whole column of LED light are used to neutralize the charge of the non image part on the OPC organic photoconductor, and from black and white monochrome to four imaging engine units. CMYK four-color powder is directly transferred on the printing paper, or indirect toner transfer is done through the flexible transfer belt, which can cope with the rough paper It can also prevent OPC from being damaged in advance due to direct contact with the printing paper. When it comes to color electronic imaging printing technology, the 1993 ibex93 Birmingham printing machine exhibition in the UK is a new beginning, including the Belgium Xeikon color control dcpi with double sides, ten OPC imaging rollers, the roll type color toner printer, Agfa also developed Chromapress with the same engine, which is also a double-sided 5+5 printing method. In addition, indigo company is led by Dr. lander Landa, An OPC imaging ★ cylinder was invented, which can print one color at a time, four colors at a time, and up to seven colors of P-1000 electronic ink printing machine. It also has blanket transfer printing, which is close to the lithography printing quality. Today, indigo machine, which has been acquired by HP company, has reached a peak in quality and efficiency after the 7000 model comes out, and it can print roll to roll plastic materials, which is very advantageous in application. From Xeikon to d-8000, the efficiency of youyou has reached the capacity of 220 A4 pages per minute, but the improvement is still limited

today's toner digital printing equipment still has the most varieties in Quanlu and Fujitsu Quanlu. The latest generation of igen 4 is available for paper supply, with 110 A4 printing capacity per minute. In addition, there are dc-8000ap and 5000ap high-level models. Fujitsu Quanlu has launched the C 700 toner digital printer developed in Japan, which has passed the German Fogra color certification. In the high-speed roll to roll color toner printer, Xerox 490 is a single machine, and X 980 is a combination of two machines, forming a single print before and after. In high-speed toner printing, Germany's Aussie OC company can compete with full video. The color stream 10000 model is upgraded from monochrome, two-color and three-color cs-9600. It adopts a double transcribe tape system, with a printing capacity of 800 pages per minute A4. OC's sheet fed digital printer CP 900 adopts the world's first seven color hair color method, so the color toner overlap is not much. Green is generally yellow 100 + Blue 100, plus some magenta and black. Cp-900 only has green ink, and a little black ink is OK! So the speed of A4 per minute is 35. Both Quanlu and Ossi have high-efficiency black-and-white roll to roll inkjet machines, which are faster than color. In Japan, in addition to Fujitsu Quanlu, Ricoh Ricoh, Canon, Konica Minolta, Oki, Toshiba, Olympus and other companies have launched toner listers with a maximum A4 printing capacity of 70 ~ 90 pages per minute. At the bottom, there are 30, 40, 50, 60 and other toner printers with the same speed. The entry-level models range from more than 300000 yuan, 70000 ~ 800000 yuan, more than 1 million yuan and so on. If the sheet fed paper is high-end, the price ranges from 6 to 25million yuan, forming a cost-effective market with production capacity not commensurate with the price. If you buy a high-level color printer with 80 A4 prints per minute for 6million yuan, why does the highest-level printer of the same brand charge more than 20million yuan, 3.5 ~ 4 times the price, but the speed rises from 80 to 110 per minute, and the production capacity is only 40% more. The manufacturer only said that the equipment with more than 20million yuan is industrial grade, which can withstand 24-hour operation without quality change. However, unless the business is very firm, no one dare to introduce such a good type of machine rashly. Spend 50000 or 600000 to buy an advanced machine with 4-50 A4 prints per minute. Use it first, and it's not too late to advance until you figure out the clue. Anyway, the money left is still very easy to use, and you have to wait until you figure it out

IV. market first, equipment first

I believe that for people related to the existing printing plant, output center or other printing design, from the concept of printing production with edition, if they want to enter the printing production market without edition, we temporarily lock the investment amount at more than 10million yuan, otherwise it is difficult to calculate the market and investment and return mode of buying a flagship equipment such as I Gen 4 or HP indigo P 7000. Machines and equipment below 10million yuan are also divided into several levels. The first is to look at the network capacity, because in the future, these printing devices will only undertake the work of large companies or conference centers. In addition to the internal network system to print the workpiece content files, there may also be prints from domestic and foreign networks. On the basis of a certain Internet receiving and transmission bandwidth, otherwise it is unlikely to undertake external files and lose business opportunities. The server of large-scale printing equipment is generally of sufficient capacity, which only depends on the arrangement of enough bandwidth to have good transmission efficiency

a lot of success belongs to people who are prepared. If you want to start at high speed, you must squat down first to have high-speed starting momentum. As for buying a machine before waiting for customers, or finding customers first, it is a little too late, because the effective lead time of modern equipment will not exceed one year. Therefore, you should first study to a familiar degree. There are 30 to 40% of them in the market Before loading, it is necessary to check whether the loading handle is placed in the unloading position before it is introduced, and then add a little higher, so that it is possible to reach a 50% to 60% basis to maintain the initial operation level. Otherwise, it can only be reduced by spending half of the money on advanced equipment, spending a little more time on production, and upgrading when the business is enough. While the price of 15 A4 color laser listers per minute is 400000, and the machine bought by 4million has only 60 capacity per minute, which is not 10 times the capacity. The machine bought by 20million is only 110 per minute, which is not five times the capacity of the equipment with 4million yuan. Therefore, the gap is rip interpretation and servo capacity, and more importantly, the charge price per print produced. The lowest order machine is five times that of the high-order equipment, Manufacturers also take this opportunity to open up the gap in the market of equipment. Otherwise, if they buy five or ten more advanced models, their production capacity will be large, and the purchase price of equipment will be lower. If you wait until it is cost-effective to buy equipment, safety is safe enough, but you often lose the market opportunity, so learn while doing it, and don't rush to invest too much money at one time. Just like Deng Xiaoping's method of "crossing the river by touching the stone", you must walk along the river bed, swim a few steps to cross the subsidence, and maintain good physical strength. Many people want to take a step in the plateless printing market, and there are not many successful cases. Most gate sizes take 1/2 ⑴/3 of the wall thickness of plastic parts; The number of people who have their own basic work, such as the bill printing of banks and card issuing companies, will one day transmit pod to each other to print on demand. After this era comes, there may be opportunities for rapid growth in performance
