Traditional offset printing, gravure printing, relief printing and screen printing all belong to the category of plate printing, which will be discussed later in this chapter. The rise of lithography technology has also brought a certain impact to the traditional printing industry. Lithography technology is different from the traditional printing production process, including photoelectric imaging printing, laser imaging printing, inkjet printing, magnetic printing, heat transfer printing and so on. Prepress is similar to digital prepress, but does not need to output film or plate. Files can be output directly to digital printing devices. With online or offline binding equipment, the production process can be completed. It has a wide range of applications, including advertising, monthly reports, a small number of books, posters and proofs.
Lithography has many characteristics. Generally speaking, there are the following points: - no film and plate - personalized printing - on-demand printing - no printing equipment time - overprint is very accurate - no professional printing operator - can work online.
Paperless printing is very different from traditional offset printing, gravure printing, relief printing and screen printing. Traditional printing must rely on a specific image carrier, such as printing plate or screen plate, and the image and image of printing plate can not be changed. Plate less printing, as the name suggests, is to get rid of the limitations of the printing plate, use computer software to convert images and graphics into electronic format and print them directly or indirectly on the substrate. At the beginning of its development, gravure printing was mainly used for fast printing, short printing and internal documents. At present, the technology of plate less printing has made great progress. The performance and printing quality of prepress equipment are very close to that of traditional offset printing. At present, it has been widely used in the field of commercial printing.
The plateless printing process is more technologically and environmentally friendly than the traditional printing process. Because all prepress processing, including image and composition, is completed on the electronic platform, there is no need to use film, which greatly reduces the demand for developing fluid, developing fluid and other chemical liquids, and directly reduces the pollution to the environment and ecology. Most paperless printing does not require liquid ink, but dry toner. Inkjet equipment uses liquid ink, generally water-soluble ink, which can be easily sprayed onto the substrate through a very thin inkjet nozzle. Paperless printing equipment used in commercial printing is classified according to imaging technology, including electrostatic printing, inkjet printing, magnetic imaging printing, electro-ionic printing, etc. Next, Shenzhen Bao'an Bolin Printing Co., Ltd. introduced the classification of imaging technology濟南印刷廠講解的內容 更多的內容 請咨詢公司官網http://www.703248.com/
