The invention and development of the Printing Machine play an important role in the spread of human civilization and culture.
In 1439, Germany's Teng Fort made wooden letterpress Printing Machine, this vertical spiral hand press brush although the structure is simple, but it has been used for 300 years; 1812, Germany's Koenig made the first Taichung flattened letterpress Printing Machine; 1847, the United States of America Hoye invented the rotary press; 1900, made of six-color rotary press; 1904, the United States of America Rubel invented offset Printing Machine.
Before the 1950s, the traditional letterpress printing process in the printing industry to occupy a dominant position, the development of the Printing Machine to the main letterpress Printing Machinees. However, the lead alloy letterpress printing process has the disadvantages of high labor intensity, long production cycle and polluting the environment. Since the 1960s, with a short cycle, high productivity and other characteristics of the lithographic printing process began to rise and development, lead alloy letterpress printing is gradually replaced by lithographic offset printing. Soft letterpress printing, stencil printing, electrostatic printing, inkjet printing, packaging printing, advertising printing has also been developed.
World printing machinery since the 20th century, 80 years has made great development.
The first stage was the heyday of the development of the offset printing process from the beginning of the 1980s to the early 1990s, and the maximum printing speed of the sheet-fed offset press was 10,000 impressions per hour. A four-color Printing Machine before the pre-adjustment preparation time is generally about 2 hours. Automatic control of the Printing Machine mainly focused on automatic knot paper, automatic paper collection, automatic cleaning, ink automatic detection and automatic adjustment of ink volume and remote control and so on. During this period in addition to monochrome, two-color machine, each leaflet offset press manufacturers almost all have four-color machine manufacturing capacity, most manufacturers are able to create paper flip mechanism, double-sided printing.
The second stage is the 20th century, the early 90s to the end of the 20th century. Into the 20th century, 90 years, with a single sheet of offset press as a symbol of the international printing machinery design and manufacturing level forward a big step forward. Compared with the first stage of the model, a new generation of models to further improve the speed from 10000 Indian / hour to 15,000 Indian / hour, prepress the pre-adjustment time from the first phase of 2 hours or so greatly reduced to 15 minutes about. The automation level of the machine and the production efficiency are also greatly improved.
Into the 21st century, printing machinery ushered in the third stage of development. Some models of sheetfed offset presses can reach 17,000-18000 print / hour, but manufacturers do not strive to improve the maximum printing speed of the press, but through the application of information technology to further reduce the prepress preparation time and replacement The time of job pursuit of higher productivity.
