Printing plate and its development trend

In recent years, with the application of computers in the printing industry, epoch-making revolutions have occurred in printing technology and printing plates; printing processes have been reduced, printing cycles have been shortened, and product quality has been improved. The status quo and development trends of lithographic printing plates are now described below for reference.
First, the general PS version ... ... PS version of the structure is composed of support body, hydrophilic sand layer, oxide layer and photosensitive layer of four parts, each part has its own unique properties:
1. Supports, at present, most of the support for the PS plate is mainly made of aluminum alloy plates. 2. Surface treatment of aluminum plates (namely, the formation of sand layers and oxide layers)
3. Photosensitive layer II. Advanced V series PS version "VG"
In recent years, Fuji Photo Film Co., Ltd. in Japan has made major improvements to the ordinary PS version, and this improved PS version is called the advanced V series PS version of "VG." The highlights of the improvement are described below.
1. A light-diffusion-suppression type high-sensitivity photosensitive layer was successfully developed.
2. Developed super multi-layered sand.
In order to solve the hydrophilicity and printability of aluminum plates, FUJIFILM has adopted the following new technologies for the surface treatment of aluminum plates:
(1) Controlling technology of the angular width of pit openings (2) Smooth processing technology for pit surfaces (3) High-density distribution technology for medium-wave pits 3. Advantages of advanced V-series PS plates (1) Shortened Printing preparation time improves the operation rate of the equipment.
(2) Improve water retention and prevent network expansion.
(3) Improve the quality and efficiency of plate making.
Third, the new technology without horizontal printing (a), the origin of the non-horizontal version (b) the structure of the non-horizontal version (c) the characteristics of the non-horizontal version (d) the characteristics of the non-horizontal printing ink, no horizontal printing ink is no One of the important components of the horizontal printing new process system engineering, it has a great difference with the general lithographic printing ink, mainly in the following aspects:
1. Composition of ink 2. Viscosity of ink without horizontal printing plate 3. Drying without horizontal printing ink:
(5) Temperature control equipment for printing presses... At present, there are three methods for controlling the temperature of printing presses:
1. How to cool the water in the ink roller: ...
2. The method of cold water in the rubber roller: ...
3. The way to blow cold wind: ...
(7) Development Trends of Levelless Edition and Computer Direct Plate Making Technology (CTP Plate)
With the development of high technology, digital printing technology has become a hot spot in the printing industry in the world today, which has aroused the attention of the printing industry in China. The development of representative CTP printing equipment and printing plates is described as follows:
(1) Classification of CTP Plate Printing Equipment 1. CTP Off-line Plate Making (Computer To Plate)
2.CTP on the printing press (Computer To Press)
3. Digital Direct Print (Computer To Print)
(II) CTP plate making light source (3) Types of CTP plate 1. Silver salt type CTP plate 2. Photosensitive resin type plate 3. Thermal type plate material (4) Conditions for ideal CTP printing plate 1. With high resolution and speed 2. Must operate in the open room 3. Must pay attention to protect the environment 4.
