Chicago printing Expo tour

this Chicago printing Expo (print 01) was held at the McCormick Exhibition Center in Chicago, USA. From September 6 to September 13, 8 calendar days, more than 850 companies participated in the exhibition, with 3 pavilions and an exhibition area of 100000 m2. This exhibition is at a time when the printing industry is transforming to digital technology. Many products that were only in conceptual design or prototype design at the original exhibition have reached the mature stage of market promotion. However, compared with the last (print 97) Expo, the exhibition area was reduced by about half due to the economic recession in the United States; It was also attacked by terrorists on the 11th, and the number of visitors was greatly reduced

the slogan of this Expo is "from design to delivery" (de 2 DE), which focuses on the display of digital printing machines, direct plate making printing machines (DI) and direct plate making technology (CTP). The exhibits of traditional printing machines are greatly reduced

I. digital printing press

digital printing press is one of the protagonists of this exhibition. Heidelberg exhibited for the first time the "nExpress" 2100 color printing machine that can be put into practical use; Xerox exhibited the "future color" color printing machine for the first time; Indigo exhibited the "Platinum" color digital printing machine for the first time; Saiangel exhibited the "versa mark" color table printing machine for the first time; Canon and Saikang also exhibited their color digital printing machines. According to the forecast, from now to 2005, the color digital printing will increase by 18%, while the traditional offset printing will only increase by 3%. Therefore, this is a huge market. Later, we visited Fang brothers printing company in San Francisco. We saw a digital printing workshop composed of two Xerox docucolor 2060 and three Xerox docutech 135. The business was busy, and we really felt that digital printing had become a reality

Xerox has an unshakable dominant position in the field of color digital printing machines. Three years ago, it launched the first generation of docucolor series, including docucolor 12 and docucolor 40; Last year, Wencai 2000 series was launched, including Wencai 2045 and Wencai 2060; This time, the "future color" color digital printer was launched, which adopted double-sided color printing linear paper path, digital blanket dB (Digital blanket), and intermediate belt transfer (IBT) technology. The printing quality and durability were greatly improved, and it can adapt to g/m2 paper. The printing speed reached 6000 prints/hour, and the printing volume can exceed one million prints. Xerox publicly announced that in the near future, the first place in the sales of printing presses in the world will not be Heidelberg, but Xerox. This is not impossible

Heidelberg is also catching up with the trend of color digital printers. Through nExpress, a joint venture with Kodak, it has developed 2100 type color digital printers. The rugged offset press shape design is composed of black-and-white metal shells. Its reliability is guaranteed by the use of durable alloy parts, solid steel frames and bearings of accurate imaging modules. In order to achieve stable high-quality prints similar to offset printing, nexqtm quality control system is adopted, including seven patented technologies: nexq paper drying device, nexq automatic paper positioning device, nexq imaging device, nexq fixing device, nexq ipsilateral double-sided turnover device, nexq environment control system and nexq cycle process control. The rubber roller of nExpress 2100 can print high-quality prints on various printing papers of g/m2. This special rubber roller has a high surface finish, which reduces the wear of the imaging roller and prolongs its service life. The maximum width of printing is 350mm × 470mm, with a resolution of 600dpi, and a printing speed of 2100 prints/hour. It is equipped with 1 450mm paper height and 2 100mm paper height three paper feeding boxes, 1 30mm paper height and 1 600mm paper height receiving box, and is equipped with a computer control system

indigo has launched a new "Platinum" six color digital printing machine, which uses ITT (image tracking technology) to accurately focus the imaging laser on the photo imaging plate (PIP). This six color machine has 4 colors plus 2 spot colors, and the printing format is 320mm × 464mm, the resolution is 800dpi, and the printing speed is 2000 prints/hour

Canon exhibited CLC5000 color digital printing machine, which adopts automatic image refining (air) technology, and can reach the printing speed of 3000 prints/hour

Xeikon exhibited the CSP 320d color printing machine produced by the manufacturer of drupa 2000 tensile testing machine to talk with you about the installation process of the AD card of the microcomputer controlled electronic universal testing machine, and OCE exhibited the cps700 color digital printing machine

SDP, Scitex digital printing Inc., a subsidiary of Scitex group, exhibited the BCP (business color press) at the exhibition for the first time. Since 1995, after six years of development, Symantec has introduced BCP to the market. BCP is the first color digital table printer in the world, with a printing speed of 150m/min. At present, BCP with printing speed of 300m/min is being developed. Its core technology is Versamark inkjet print head. Its printing width is 9 inches (228.6mm) and resolution is 300dpi. The minimum configuration of BCP is 4 print heads, which can print single format and four-color prints, and the maximum configuration is 16 print heads, which can print double-sided and four-color prints. Most desktop inkjet printers use an on-demand drop feeding scheme, where each drop is sprayed onto the paper. Saiangel digital printing company adopts different technologies, that is, continuous flow inkjet. In this scheme, the stable ink flow of ink drops is generated constantly. Most of these ink drops are recycled in the ink collector by electronic deflection, and only the non deflected ink drops continue to move forward until they are sprayed on the paper. In operation, the ink is pumped into the droplet generator, which is the chamber in the imaging head. A piezoelectric crystal is used to oscillate the chamber of the ink drop generator at a frequency of 110khz. The holes in the chamber cover a plate on which a row of holes are accurately manufactured. On the 9-inch print head of the BCP machine, this plate has 2700 identical fine holes, 300 holes per inch. Each time the print head oscillates, 2700 ink drops (of the same size, all moving in a straight line) are generated from the baffle plate of the print head and sprayed onto the paper. The ink drops leaving the print head do not carry charge, but just leave the baffle plate, they pass by the "charging plate" (an array of electrodes with high efficiency in preheating the wire core and drying the cable core, one electrode for each ink drop). Give each electrode a positive pulse with well controlled time, so that the corresponding ink droplets are positively charged. Next, the ink drops pass through the negatively charged charging plate. The charged ink drops turn to this plate and are pulled into the path of the "ink receiver" (a small ink collecting tank leading to the circulating pump), which no longer makes the ink drops go in the direction of the paper. The uncharged ink drops continue to move in a straight line and hit the paper

bcp printing is not as good as the printing quality of a single sheet color digital printer. However, due to its high-speed printing characteristics, its market mainly includes direct mailing of bills, pamphlets such as operating instructions or catalogues, lottery tickets and other fields, especially printing color advertisements on bills such as bills and credit card bills. This is a good choice, which can reach the speed of 2000 printing/minute in A3 format, And the content and image of each page are variable. In addition to banking and telecommunications, retail, insurance, utilities and other sectors are also very interested customers

in terms of black-and-white digital printing machines, the sheet fed paper feeding methods include the digital bully 9110 (A3 format, 110 pages/min), Xerox's Wenji 6180 (A3 format, 180 pages/min) and Japan screen V200 (A3 format, 200 pages/min) exhibited in Heidelberg; In the aspect of continuous paper feeding, there are OSI 8090 (A3 format, 744 pages/min), Saikang 7000 (A3 format, 80m/min) and saiangel MSP (150m/min)

it can be seen that new terms such as DB technology, iBT technology, nexq technology, ITT technology, air technology, Versamark technology mentioned above, the field of color digital printing machine has become a hot spot in technology development. Various patented technologies emerge in endlessly, and have become the most dynamic hot spot in printing equipment, which has revolutionized the traditional printing industry

II. Direct plate making printing machine (DI printing machine)

10 years ago, at the print 91 exhibition in Chicago, Heidelberg adopted pressek's Di technology to launch gto-di printing machine, marking the beginning of a new era of direct plate making printing machine. Today, there are more than 1600 Di printing machines in various printing plants all over the world. At the print 01 exhibition in Chicago, it seems that every printer manufacturer will enter the di printer market

in the field of Di printing press, since the direct plate making technology is generally not developed by the printing press manufacturer, the concept of Di technology supplier came into being. At present, pressek and Creo are two major Di technology suppliers

as early as the late 1980s, Dr. Robert Howard of pressek successfully persuaded Heidelberg company to change GTO small offset press into di press. After several years of technical improvement, the qm46-di printing machine was launched in 1995. It adopts the solution of wrapping the web plate from the inside to the printing cylinder, imaging through the ablative thermal photosensitive method, and adopting the waterless offset printing process. So far, 1500 sets of this machine have been successfully sold. Then pressek realized the Di technology on the 74karat printing press of KBA company, the scheme on the adashite 52 and 74 series (400di and 745di) printing press, and the scheme (3404di) on the Liangming 3404 printing press. Both of them adopted the 915nm wavelength infrared laser and Pearl ablation heat sensitive water-free offset printing plate. In 1998, pressek developed the Profire Di component based on the water offset plate (Anthem) direct plate making technology, and implemented this scheme (474epii-di) on Sakurai 74 series printing machines. Presstek has become a Di technology supplier of Heidelberg, gaobao, Adast, Liangming and Sakurai from waterless offset printing to waterless offset printing Di technology and from design for printing machine to standard Di components

if one day Dr. ERT of Creo had a genius like Dr. Robert Howard, he had invented the di patent for imaging on the printing cylinder as early as 1995. First, he developed the direct plate making system of Heidelberg SM74 Di printing machine. From the beginning, he completed the development of water offset printing Di technology based on the thermal version with water offset printing; Subsequently, this scheme (project d) was implemented on Komori's 122 series printing press, using 830nm wavelength laser and square spot technology in less than 4 minutes. This is the first printing machine to realize Di on the boot

these Di printing machines automatically install the printing plate on the printing plate cylinder for imaging, just transplant the CTP device to each printing unit of the printing machine, and the printing plate is still required in this process

Creo, in cooperation with Agfa and Manroland, developed a direct plate making digital printer (DICOweb) with erasable thermal transfer imaging layer in 2000. This model has no concept of printing plate. It is a printing machine between di printing machine and digital printing machine. The process is
