Many manufacturers have classified CT Press as a digital printing machine, like this Komori's chrysalis full PROJECT four-color machine, using Creo's thermal light source head and square dot technology, and the wide 40" machine takes only 4 minutes. It is possible to complete all kinds of printing plate operations, which has led to a significant increase in productivity that was previously deferred due to the lengthy change of plates and platemaking. Due to the use of the traditional wet-watermarked version, there is a general general foreign version capability. Workflow like this is very It is easy to be a pattern of printing and printing, but it can only be regarded as an evolutionary process. Although the machine can complete a "fixed printing plate" with an imprint information file, it cannot be changed to output a different imprint content. As a result, even though it is an extremely satisfactory improvement in production, it still can only be regarded as an evolution, not a digital revolution.
Therefore, the KBA Karat 74, Heidelberg QM-46DI, SP-74DI, Screen TurePress, Sakurai, and Yardash DI, together with the manroland Dico web caused a stir at the conference, she has a reversible rotation of the plate cylinder Printers, plates can be reused hundreds of times, do not have to be replaced, so it has a very positive role in eliminating the plate removed and installed on the replacement time, but this is still in the fixed plate form, to enter the change of change Imprinting is still not the same production mode.
However, we cannot say in the evolution trend that DRUPA2000 has no reforms to follow. Like CIP3, which was jointly developed by dozens of manufacturers, it can integrate pre-press, printing, and post-press sharing information programs across the company's brand. The trouble of reconstructing information files at different stages of program files disappears. Even after the RIP, the distribution information of various color printing patterns can provide information about the ink key opening degree conversion information of each printing unit of the printing machine. Although this is a traditional printing method, it is due to information flow. Sharing and greatly improving the future production of dimensional accuracy and ink supply accuracy, but also save valuable time and production costs, this is not a comprehensive change, but it is an outline of understanding through the process, especially in a large number of small quantities of markets can be very effective Changes in information flow will contribute to the future competitiveness.
Unprinted variable prints are making great strides
The "variable" imprinting (printing) method without printing plates is making great strides. This was independently exhibited by Xerox All Record Company in Hall 18, showing their intentions in the printing field and how they wanted to enter this original machinery. Factory-based supply system.
In black and white, there are 1300 A3 prints per minute, approximately 10,000 prints per hour on both sides of the chrysanthemum, and 2,000 prints per minute. It is more resistant to traditional typographies. 70 sheets per color and 80 sheets of capacity can be used for cover printing. The concept of full recording is systematic processing, that is, the inner pages are printed from the first sheet to the last sheet, together with the printed sheets. Bind into a book, and then print the second book, so that an online production process is completed.
This kind of subversion of traditional printing production and processing methods brings entirely different production concepts, and even the possibility of printing in the next three or five books, as well as the ability to print books for a small number of people, and for a limited number of books to be sold, can be reprinted. Personalize the different printing and publishing, the most important is the ability of network printing, greatly beyond the printing of the original printing plate. Therefore, at the time of the Printec Singapore exhibition in May 1999, Heidelberg's president would regard the entire recording as the biggest rival and he would visit him personally.
Xeikon uses LED and optical drum imaging technology, has 800dpi and 6bit resolution per pixel, has its own extraordinary performance, the original rotation is now also a comprehensive diversification, Zhang Yeji, trademark processing after the rolling type, black and white high-speed printing This is mainly to mimic the lithographic texture and integrate into this market.
Indigo was most active on the DRUPA2000. He saw that the founder Dr. Barney Landa had a good brilliance on his face. The main reason was that the speed was almost ten times faster. On the one hand, the printing speed increased by 2.5 times and the number of colors changed from a single composition to four. With multiple sets of prints, his theater is very attractive and persuasive, and it is hoped that their after-sales service will be just as exciting.
Barco also exhibited multiple rollers, Canon, Toshiba, Sharp, and others in this area. IBM and Oce` are the largest computer companies in the United States and Germany. Their printing equipment is based on the path of toner dyed drum imaging. They are also new to the printing market, and they must learn to process and order trimming and trimming. Still more, but they also have large capital.
Scitex is divided into two major parts. The related CTP and negative film output parts are Creo's cooperation. In addition, big posters, the fastest print heads, and high-speed large-size 600 dpi prints are positioned on large posters (about 1.6 meters wide) and various kinds of printing. Each hour has a printing capacity of 80 square meters, about when the chrysanthemum has a full 112-sheet printing capacity, so in the small amount there is a long strip-like print in its market is its specialty.
A company's digital printer has just been listed, but the quality is still somewhat unsatisfactory, and the discussions between the two sides turned out to be something I was looking for, and it was really an arrogant state of mind before being listed.
The DRUPA2000CTP is still difficult to determine
Although CTP is a very hot topic, and development is still very different, it is difficult to make the following conclusions. The head of the output center of the same company says, "I will still buy a negative film output machine!" This is also justified because the printer output machine faces three uncertainties, including: the factors that the equipment and materials are still changing, whether the printing machine has any problem with the printing, and whether it can be output correctly after two or three years. If there are too many uncertainties, it is still necessary to wait for the conditions to be re-introduced, although it is safer to lose business opportunities.
Small-size silver version of CTP is relatively easy to establish, based on polyester fiber plate and silver salt photosensitive infection imaging method. Newspapers use CTP, which has low resolving power but pays attention to production speed. There are more than two hundred plates produced per hour. Gravure and Flexo also take the road of CTP. Gravure is mostly based on electronic engraving. Only Japanese Think Company emphasizes the advantages of ink layer uniformity and ink consumption by corrosion, which is beneficial to the use of water-based ink. Some of the storage and handling engraving machine automation systems are also gravitational and provincial humanization considerations.
CTP's Flexo flexo is still black and white outside the photosensitive film, so pure Filmless no film, still need to be exposed to the formation of anti-developer imprints, technology has entered a very mature stage. The resin plate is also applied to the rear section of the typographical printer or the gold and silver and special colors. Therefore, in many cases, large-size photosensitive resin plates are also used. It was only known to Europe that the elasticity of the roller under the Flexo plate, like the underside of the typography rubber roller, has a great influence on the printing ink and the shift of the print.
Various printing presses have been connected with digital information
Various printing press manufacturers, in addition to Ebara, Yoshiaki, and Akiyama, have yet to work hard with digital information. Others are working harder. On the one hand, it is the production of on-machine plate-making DI. Download the page file, you can print on the mechanism printing, like Heidelberg pigmented digital printing (printing) machine, Manroland in addition to the Dico web, but also to Xeikon, and approached Agfa! Relatively KBA cooperated with Karat and Scitex, and also imported Indigo digital presses. Dainippon Screens were not willing to use prepress equipment. Once the on-board platemaking equipment became popular, the remaining screens of TaigaSpace operating system and scanners could be sold.
Chrysanthemum full and medium and small size typographers, Heidelberg has a lot of advantages in terms of volume, but Roland is not to be outdone. This time introduced two small and medium-sized typographies, including the new R-200 with a double-diameter cylinder, giving up a bicolor five. Roller structure, intentional and SP-74 seedlings, another R-500 type, using a double diameter roller Dajujuan, is a cardboard printing series, mainly exquisite small size packaging and trademark thick cardboard printing.
Heidelberg's CP-74-6+LX type offset press is also designed for small-size fine cardboard printing, because the small machine holds a larger diameter printing cylinder, so the speed increases, while the printable circumference length is increased from the original 520mm to 600mm, can be more Efficient mold ejection. KBA's R-74 is also a product of the same grade, and is equally prone to various paper jams.
The large-size Zhangye printers are originally Roland R-900 and KBA R-162. Japan Komori L-X44 or X50 still have not been exported. Mitsubishi Heavy Industries has exhibited 50 times in the first overseas exhibition of DRUPA2000. Zhang Yeping printing machine, do not look very thick.
For machines above 40 inches, there are very few simple four-color machines. Many are five-color, six-color, and light. There are also eight colors and ten colors plus flipping, which means that they are produced at one go. The glazing method now uses double glazing and double drying units, plus the extended discharge rack structure, it seems very complicated, the reason is to change, a glazing an extinction, or a seat swatch special color (or gold and silver) another Polishing, there are two drying units between the two, and finally drying properly with IR or UV on the extended discharge rack.
When UV glazing was used in the past, the color printing ink must also use UV UV ink, and do pre-drying one by one. This would add a lot of cost. Now, the double tower is used, and the front seat uses water-based acrylic. Polishing liquid, color printing using the normal lithographic four-color ink, followed by two units of drying, and then formally UV UV coating layer, this, the previous operation can be traditional, the back of the two coating gloss is better There is no general ink layer that has not been rejected by UV varnishes.
Rotary typographer is DRUPA2000 big show
Rotary typographer is one of the masters of the DRUPA. Other exhibitions in the world, as long as there are two or three rotary typographic machines exhibited, it is amazing, but DRUPA2000 has more than a dozen large-scale wheel presses and commercial rotations at one go. The machine was exhibited, and a giant newspaper machine was exhibited.
KBA, Manroland and Heidelberg have four exhibitions each, and commercial rotary printing presses have 64 pages of giant chrysanthemum four times larger size. Japan Komori also has System 38 display, and the third world India has two factory shows. There are three manual rotary printing presses. There are no drying equipments. Solna has also exhibited them, and there are no less than ten other rotary presses for other reports. This number can be said to have broken the scale of the calendar year, in addition to synchronous independent motor drive technology, few people pay attention to the direction of improvement, because seamless Gapless technology is not everybody wants to use.
DRUPA2000 flexo and gravure
Flexo Flexo and gravure are widely used in flexible packaging and paper bags. In particular, European use of gravure in soft packaging and plastic bags is lower than that of Flexo. Large size of gravure has a certain market in terms of publishing, and it also provides excellent quality. The lithography can't reach the level, so with a multi-gravure electronic engraving machine and an extra-large 2.4-meter or wider gravure printing press, KBA is one of the best. It is still a giant satellite pressure roller and four to six printing units around it.
