Analysis of the production of small offset printing machines in the world

small format offset printing machines, as the name suggests, refer to the effective printing area of 520 × At present, the most common small offset printing machine with a format of less than 360 (mm) refers to a small offset printing machine with a format of A3

in the past 10 years, small format offset printing machines have experienced many changes. In the early 1990s, the development of traditional small offset printing machines reached a peak. Light monochrome multi-function small offset printing machines became the main model in the short version fast printing market, with an annual installed capacity of more than 10000 units worldwide. During this period, more than 15 offset printing machine manufacturers (excluding China) produced small format in the world, and the more prominent manufacturers were Heidelberg in Germany, leyoubi and Hamada in Japan

in the latter period of time, small format multi-color offset printing machines began to develop, and many manufacturers came up with their own mature two-color and four-color small format offset printing machines. Since the mid-1990s, the market of small format offset printing machines has been changing. Many manufacturers have been strongly impacted by the rapid development of the new technological revolution, especially the progress of computer technology, copying technology, scanning and printing technology. High speed printers, high-speed copiers, and digital all-in-one machines are widely used in the field of office light printing, which can be high-speed, convenient, and develop aviation materials with clean logistics Copying printed matter for customers at low cost, light monochrome small offset printing machines have been impacted in the international market. Many manufacturers' sales of small format offset printing machines have declined, and some have to face reorganization or bankruptcy

in the development process of small format offset press in this decade, only Heidelberg company, leyoubi and Hamada company still maintain a certain development. These three companies have transitioned from the original monochrome small format offset press to multi-color small offset press above two colors and digital direct printing press in machine-made version

compared with the world's advanced technology, the distance between the development of small offset press technology in China is not shrinking, but further widening. Especially in the field of small format offset press, we are still at the level of the development of international small offset press ten years ago. In foreign countries, the production scale of small monochrome Offset printing machines is constantly shrinking, and the field of short version rapid printing is developing towards digitalization and polychromism and high automation of traditional offset printing machines. However, China's small offset printing machine industry is still developing at the low level of monochrome machines, killing each other, swarming the ground production and scale, and the number of manufacturers has increased from 10 to more than 40, It is four times the total number of small offset press manufacturers in the world

all the technologies of China's small offset printing machines come from abroad. From history to now, no enterprise or research unit can even develop 3D printing equipment by itself, which is enough to design and develop small offset printing machines independently. From Yingkou Guanhua (formerly known as Yingkou copier factory) produced China's first small offset press in 1976 to the formation of a pattern of small offset presses with multiple varieties, specifications and diversification, which shows the different prosperity of small offset presses under the specific historical conditions of our country

in China, there are a wide variety of small offset presses of various models, and their product technology sources can be divided into two modes, namely, the Japanese mode and the European and American mode

the technology of small offset printing machine comes from three channels:

the first channel is to purchase or introduce a full set of production and manufacturing technology (all drawings, complete assembly, commissioning and inspection processes, as well as some special tooling, fixtures and equipment). There are only two manufacturers in China, Yingkou Guanhua and Weihai Bintian

the second channel is to buy only foreign product drawings and some parts, rather than complete assembly, commissioning and inspection processes and equipment. There are also two manufacturers in China

the third channel is to purchase foreign prototypes, and obtain drawings for production and manufacturing through various abnormal means with manufacturers who have copied surveying and mapping drawings

compared with the same type of small offset printing machines in developed countries in the world, except for manufacturers that have introduced a full set of technology, such as Weihai Bintian and Yingkou Guanhua, the vast majority of small offset printing machine products in China have a certain gap in terms of internal quality and performance stability, as well as the processing accuracy of parts and components and the quality stability of the whole machine

at present, small format offset printing machines in China can be divided into four categories: desktop small offset printing machines, monochrome light small offset printing machines, multi-functional small offset printing machines and heavy commercial small offset printing machines

about small desktop offset press:

small desktop offset press is a small desktop offset press with relatively simple structure, low performance and lax requirements for print quality. The main purpose of its initial design is office use. In foreign countries, desktop offset printing machines are almost eliminated abroad, and only Japan's China Eastern Airlines is still producing a small number of 820 desktop offset printing machines

at least eight enterprises in China are still producing desktop offset printing machines

about monochrome light-duty small offset press:

monochrome light-duty small offset press is a light-duty monochrome printing small offset press with relatively simple structure (compared with pure commercial printing press), but high quality of printed matter, good quality performance, high speed, simple and practical operation. The original design is high-end office light printing, which uses cerium based materials. Some customers are also used for short version fast monochrome commercial printing

in foreign countries, only a few manufacturers, such as leyoubi in Japan, Hamada, China Eastern Airlines and albody in the United States, are still producing light monochrome small offset printing machines

there are only a few manufacturers and products producing light monochrome Offset printing machines in China, among which Yingkou Guanhua's yk1800 series is still produced in large quantities. From the history to the present, the light monochrome Offset Press has always been the absolute advantage of Yingkou Guanhua, and no manufacturer can compete with Yingkou Guanhua. So far, Yingkou Guanhua 1800 offset press has put more than 20000 sets on the market

about the multi-functional small offset press:

the multi-functional small offset press is based on the light monochrome small offset press and expands its functions according to the needs of the printing market, such as adding tape rules to cross the bridge to realize the chromatic printing function, adding two-color heads to realize the two-color printing function, adding number printing unit to realize the functions of number printing (straight, horizontal), hole pressing line (straight, horizontal), resin printing, cutting and so on. It can realize high-quality and fast monochrome printing, It can also meet the multi-functional needs of users. Multifunctional printing machines are generally used in the field of fast commercial printing of short editions

in foreign countries, multi-functional small offset printing machines have also been classified into the category of light monochrome machines. At present, almost all existing small format offset printing machine manufacturers are producing this kind of equipment according to the 2.2 formula, among which the most famous are leyoubi and Hamada

at present, the well-known manufacturers producing multi-functional small offset printing machines in the Chinese market include Weihai Bintian, Yingkou Guanhua, Weihai printing machine, Weifang Huaguang, beiren second printing machine, and Beijing Duoyuan. These five enterprises account for 80% of the domestic multi-functional small offset printing machine market

about the heavy commercial small offset press:

the heavy commercial small offset press is a pure commercial small format printing machine, which has the structural characteristics of a large printing machine. It adopts the Feida paper feeding structure of continuous paper supply, especially the paper transmission structure adopts the paper delivery tooth row transmission, which has high printing speed and good print quality, and can meet the needs of users with a variety of functions. It is the most ideal equipment for commercial short version rapid printing

at present, only Heidelberg in Germany, leyoubi in Japan, Hamada in Japan, Shinohara in Japan, rota in Germany and Adast in the Czech Republic produce small format heavy-duty offset printing machines in the world. The heavy-duty small format offset printing machine itself is a high-end printing machine

there are not many manufacturers producing such high-end heavy-duty printing machines in China
