With the rapid development of science and technology, the world has entered the era of digitalization, and the printing process has also undergone rapid changes. Computer technology has been directly applied to the printing of the plate-making and even the control of the whole printing machine control.
In the digitalization process, various printing technology development trends are as follows:
First, the trend of development of the printing technology of flat printing The main topics of current lithography that the advanced countries in the world are studying are: 1) direct plate making technology; 2) direct printing technology; 3) no horizontal printing technology; 4) FM network technology.
The domestic multi-colored sheet-fed offset press uses ink-colored remote control, reading device, and automatic registering device, and controls and troubleshoots all production processes. In China, the ink-colored remote control device has just been developed. Therefore, we must vigorously develop a new generation of The integrated multi-color offset press continuously improves the quality of printing equipment (paper, ink, photosensitive material, blanket).
Second, the development trend of flexographic technology After the signing of the Montreal Convention in 1995, the control of CFC chlorofluorocarbon emissions tends to be strict, limiting the use of solvents such as trichloroethane and tetrafluoroethylene. Environmental pollution problems caused by solvents used in flexo plate making have always troubled the flexographic industry, and must accelerate the development of environmentally friendly new products. The first line is the development of environmentally friendly potions—new solvents for washing plates; the second line is the development, manufacture, and practical use of water-washed flexible plates. Flexo printing is evolving toward thinner media.
In the past two or three years, China's packaging industry has created a climax for the introduction of flexo equipment. By the spring of 1997, China had introduced 67 flexo production lines for narrow-width (600mm or less) multi-function units, distributed in 20 provinces, cities and autonomous regions across the country. However, the lack of support for domestic flexo printing equipment is the main reason for the rapid development of flexo printing in China. At present, we should devote ourselves to improving the quality of domestically-made flexographic printing plates, anilox rollers, and inks, and developing on-line production lines with post-printing decoration processes so as to improve the flexographic printing quality to meet the needs of the packaging industry.
Third, the gravure printing technology development gravure printing due to the large investment, the high cost of the plate, only suitable for long-term products; plus gravure substances in the gravure ink pollution of the environment, so the development of gravure is subject to certain limitations. If you can solve the above deficiencies, there may be some development. For example, in recent years, the development of gravure printing technology, especially the development of gravure printing plate making technology, will greatly shorten gravure printing preparation time, thereby increasing the competitiveness of gravure printing in the short lived and Chinese live market.
The development of gravure can be summarized as the following aspects: 1) automatic gravure cylinder electroplating process; 2) rapid non-plated electroplating engraving process; 3) photopolymer thin roll gravure process; wrapped around the drum Development of gravure; 4) Digital proofing; 5) Gravure printing machine develops toward multi-purpose, multi-color, high-speed, automation, linkage, and environmental protection; 6) Realize water-based gravure ink printing, effectively control solvent ink printing The residual amount of solvent.
Fourth, screen printing technology development trends There is no doubt that if you can develop the use of water-based ink rotary screen printing machine; if the screen printing machine is more efficient, blade pressure, speed and angle parameters can be read and can achieve program control, in When printing duplicate prints, the production can be repeated according to the procedure; if the production data can be correctly used from the prepress, the print preparation to the printing, the silk screen will be more developed.
Following the popularization of screen printing in China in the 1980s and the significant increase in screen printing in the 1990s, screen printing will certainly develop in depth and breadth. “Deep” means to develop to a higher level. The international screen printing industry has already widely applied advanced technologies such as computer design, plate making, and electronic engraving, and China is still in the stage of research and trials for these new technologies. "Broad" is the development of new screen printing products. With the continuous development of China's socialist market economy, the advertising industry is making its mark, and as a new generation of advertising products, outdoor large screen printing products will surely have a broader development prospect.

Pellet Grill

A pellet grill is a type of outdoor cooking appliance that uses compressed wood pellets as fuel to cook food. The pellets are fed into a hopper, which then moves them into a burn pot where they are ignited by an electric heating element. The heat generated by the burning pellets is used to cook the food on the grill grates. Pellet grills typically have digital temperature control systems that allow for precise temperature regulation and cooking time. They are known for producing a unique smoky flavor and are popular among barbecue enthusiasts.
