Unique pre-printing plates can be printed on the machine without the need for moist water. The non-printed portion is covered by the ink-filled silicone layer, while the printed portion is slightly recessed and forms an ink-acceptable polymer surface. The non-horizontal version is characterized by high quality, simple printing operation, and high-efficiency production without pollution, a unique printing process of water and alcohol.
History 1.1798 Austrian people Schaeffler Alosi Sencfeloler invention in the porous ... ..., so that non-oily ink non-printed stone water, and then the ink will only be stained in the grease ink printed part of the same plane there is printed and non-printed Imprinted lithographic plate format.
2. In East Asia, lithography accounts for about 75% of the total printing production, which is the most convenient and most widely used format. The advantage is that the plate making is easy and inexpensive, and the indirect printing is not picky on the paper surface.
3. Lithography uses water to keep the non-print pattern clean, resulting in instability of the ink emulsified printing density, plus the temperature, degree, imprint, ink layer thickness, printing speed, resulting in evaporation of the water evaporation and consumption changes are not easy to control In particular, the entire surface is uneven and the production technology is more complicated.
4. Although in the past some people used corrode printing on offset printers, Heidelberg used offset printing to indirectly print Lattcrsct in 1964, and Lattcrprcss added Offsct suffixes to print in stable versions, especially thick and rough. Paper is very favorable.
In the late 1960s, 3M Company of the United States used Teflon and other low thermal coefficient materials such as silicon rubber to complete the patent application of the ink-free printing method. However, it has not been commercialized.
6. In 1972, Toray Toyo Co., Ltd., a large synthetic fiber and chemical product company, purchased a 3M silicon-free horizontal printing patent and commercialized it for research and development.
7.Toray first introduced in DRUPA 77. In 1979, there was a TAP positive waterless version, and in 1983, the negative type TAN had no watermark version available. However, the problem of long-run printing stability cannot be solved.
8. Printing Machine in 1985:
1. The ink roller cooling system is improved.
2, ink improvement.
3, ink roller adjustment technology to improve, so that no horizontal printing gradually into the road by the print industry attention.
9.Toray produced water-free UV-drying ink in 1986. In 1988, there was no horizontal printing available for commercial thermosetting. In 1990, there was no horizontal version of high-resistance long-lasting film type. In 1999, CTP had no watermark version available.
10. American Prcsstck introduced GTD DI by Heidelberg in 1990. It has no horizontal printing with tungsten needle discharge imaging and laser thermal imaging in the year 95, which lays the world's leading Computer to press status. Because Presstek is completely free of development, there is no horizontal press plate making. , to achieve both the printing presses and digital platesetter features.
11. Currently using the Prcsstck DI technology Heidelberg Qm-46DI, Adast, Karat, Sakurai, Akyama, Imation, Nilpeter, Alcoa, Omso and the like.
12. The Toray plate structure consists of an aluminum substrate, a 2 glue layer, a 3 photosensitive layer (thermosensitive layer), a 4 gel layer, and a 5 protective layer. The photosensitive layer and the positive film type are photosensitive combined type, and the negative film type is a different functional structure of the photosensitive decomposition type.
13. Developing steps: 1 Remove the protective film, 2 pre-swelling, and 3 bristles development to remove the peeling part of the sealant layer and 4 stain the developed impression. It can be printed without dyeing, but the dyeing can be identified and scanned by the imprinter. The silicone film is removed from the mouth and the end of the plate. The positive film is not sensitive, and the negative film is sensitive, so that there is astringent resistance without sliding the clamping plate. .
14. With anhydrous ink, it can produce a very thin layer of liquid on the surface of silicone to prevent the ink from sticking and not sticking. In the past, it used oyster sauce because the unfavorable catalyst was not used in the post combustion system.
15. No horizontal printing Because there is no cooling effect of the evaporation of the water, the ink roller may rise 15°C above the 10,000 copies of the leaf printing machine, which is higher than the water with 8～10°C. It is unfavorable to keep the non-print part when printing. No sticking ink, the ink is divided into HNL and LL four kinds of anti-split force, but also in response to different printing speed and temperature conditions.
16. It is necessary to control the layout and the ink roller temperature in the range of ±1.5°C. Some inks are only ±0.8°C tolerant, while others are ±1.5°C. The temperature is too high will cause dirty, the temperature is too low, the ink migration is bad, and the full version is not White spots actually occur. Therefore, there is no horizontal printing conversion ink balance technology into a more manageable temperature control. In principle, there must be warm water and chilled water facilities in order to maintain the smooth start-up and printing works.
17. No horizontal printing advantages 1 Printing is easy to worry about the balance of the ink. 2 Ink concentration is high and stable. 3 fine print dot reproduction. 4 can print about 400 lines, high fax prints. 5 Reduce the occurrence of waste paper. 6 Work efficiency can be improved. 7 Small printing is easy. 8 Press Construction Simplified. The 9th edition has a strong contrast. 10 Paper stretches less. 11 Talent training is easy.
18. Unable to imprint defects 1 Patent version and ink are more expensive. Changes in the configuration of the press must be cooled. 3 printing plates have protective film can not be automatically developed to produce 4 rubber layer intolerant of friction. 5 revision fill is not easy. 6 Unsensitized plates are susceptible to aging dark reactions. Version 7 is harder to adjust to skin color and light color prints. 8 consumes large amounts of ink.
19. The waterless leaf-leaf printer is easy to find because many leaf machines have ink-ink roller cooling systems to keep the plate and the ink supply system at a constant temperature, but different considerations for the printing ink.
20. Waterless wheel precision lithography machine has MN Rolancl polyman. KBA Crotina, no water wheel transfer printer.
21. The single-fluid non-wetting system printing method uses the traditional watermarked and ink-mixed emulsified ink, but it is very important to replenish the water.
22.DI machine-to-plate conversion has a horizontal printing plate, and it is more convenient to use other external plate making methods.
23. There is no horizontal printing in the non-absorption inside with UV light on the plastic surface Credit card, CD-ROM use a lot of development prospects are very good.
24. The thermal CTP levelless printing plate will become the mainstream, and the dominant levelless printing development is mainly due to the advantages of short project, good quality, and high printing capacity that can improve the technical difficulty of personnel.
