The development and changes of printing equipment are constantly developing and changing with the development and changes of printing technology.
Since the introduction of Western printing equipment into China, China's printing equipment has experienced the process of introduction, self-control and innovation. Especially since the 1950s, China's printing and printing equipment and equipment have developed greatly. At present, China's total printing output value has leapt to the third place in the world, and the output value of China's printing machinery and equipment has entered the top four in the world. Printing equipment from pre-press, printing to post-press processing equipment is basically complete, most of the equipment is at the international mid-range practical level, and some products are close to or reach the world advanced level. A more complete industrial system for printing and printing equipment has been formed. Mainly manifested in:
1 prepress platemaking realized by "hot row (lead row)" to "cold
The shift of "row"; from "simulation" to "analog-digital"
Step to the "all digitization" transformation. The device is implemented by a single machine
DTP and further transition to CTP.
2 printing and equipment from the traditional lead printing to modern
Offset-based shift; the latest digital printing and its equipment are also available
Great development.
3 printing equipment level from low to medium to high, by monochrome
To the multi-color transformation.
4 printing equipment realized from basically relying on imports to some high-end
The equipment outside basically meets the transformation of domestic demand.
Development and change of letterpress printing equipment
From 1041 to 1048, Bi Sheng of China invented the movable type printing. In 1448, the German Gutenberg first created the lead alloy type, and gradually realized the typesetting and mechanical printing. This is what we often call the printing technology, the earliest embossing technology. In 1807, the British Morrison began to produce Chinese lead alloy type in Guangzhou, China. It is generally believed that the use of alloy lead type, the use of mechanical printing of the printing technology to this time (1807) as the beginning of the introduction of China ("Chinese Printing History" P433).
Flexographic printing is the result of the development of rubber and resin plates that turned the lead into a flexible one. Flexo printing is currently widely used in letterpress printing.
Development and changes of prepress equipment
Prepress equipment mainly includes printing information collection and processing equipment and plate making equipment.
The development of pre-press graphic information collection and processing has undergone the process of processing text and graphics/images separately into the image and text processing. At present, the graphic and text processing technology is basically adopted.
Prepress technology has undergone the development of manual plate making, mechanical plate making, photoengraving, electronic color separation, desktop publishing systems and computer-to-plate. The four stages before the electronic color separation plate are the stages in which the text and graphics/images are processed separately. The stage of desktop publishing system and computer direct plate making is the stage of graphic and text processing.
