Monochrome printing machine (2). Two color printing machine (3). Multicolor printing machine (4). Double sided monochrome printing machine (5). Double sided multicolor printing machine 2、 There are two types of printing machines according to their uses: (1). General printing machine: the so-called general printing refers to the printing method that uses convex, flat, concave and other formats, takes paper as the printing material, prints newspapers, color pages, picture books and other general printing materials as the main object, and takes the transmission of information as the main purpose, such as book printing machine, newspaper printing machine, etc (1). Special printing machine: the printing machine for special printing, mainly including adhesive sticker printing machine, hose printing machine, etc. 3、 According to the type of printing plate, there are four types: gravure printing machine, screen printing machine, lithographic printing machine and relief printing machine (1). Gravure printing machine: gravure printing is a printing method of gravure printing. Gravure printing machine is a machine for printing with gravure. Gravure refers to the printing plate with the graphic part lower than the blank part, mainly including engraving gravure and photogravure (2). Screen printing machine: screen printing is a kind of hole plate printing. The image and text part of the plate can be omitted to the substrate through ink. The screen printing plate is in the form of mesh, and the plate forms two parts: through hole and through hole. When printing, the ink is missing from the through hole part of the plate on the substrate under the extrusion of the scraper. (3). Lithography machine: a machine that uses lithography to complete the printing process. The graphic part and the blank part are almost on the same plane. (4). Letterpress: letterpress is a machine that uses letterpress to complete the printing process. The graphic part is obviously higher than the blank part of the printing plate, such as relief plate, photosensitive resin plate, letterpress plate, etc. 4、 According to the type of substrate, it can be divided into the following two types: (1). Sheet fed press: the substrate is sheet fed or other sheet fed materials. (2). Web press: take web or other web materials as substrate. 5、 Press printing mechanism can be divided into the following three types: (1). Hand press: both the press mechanism and the plate mounting mechanism are in plane shape. (2). Circular press, also known as platform press: the press mechanism is cylindrical, and the plate mounting mechanism is flat. (3). Circular press: the press mechanism and the award plate are cylindrical. |
