No horizontal imprint (top)

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 person Xue Lilei Alosi Sencfeloler invention in the porous limestone, the use of oily ink pen to write imprints, printing with water moist, non-oily ink non-printed stone water, and then the ink will only stain For the ink-printed part of the ink, complete the lithographic plate method with the presence of imprints and non-prints in the same plane.
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. In 1985, the printer 1 ink roller cooling system was improved. 2 ink improvement. 3 ink roller adjustment technology improved, 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. (To be continued)
