Five color flexographic printing presses use fluid inks with strong fluidity. Then the printing pressure is applied by the press cylinder. The monochrome flexographic printing machine, the paper straw machine, and the five color full-automatic flexographic printing machine transfer the ink on the printing plate to the substrate, and then complete the printing process through the dry surface. The printing part is the core of the flexographic printing machine. The arrangement of the printing part directly affects the operation performance, print quality, printing speed and the scope of application of printing. According to the arrangement of printing parts, flexographic printing presses can be divided into three types: stack type, satellite type and unit type. Stacking flexographic printing presses are sometimes called stacking flexographic printing presses. Independent printing units are stacked up and down, arranged at one or both ends of the main wall panel of the printing machine, or various color printing units are installed on the rack.
Each printing unit is rotated by a gear mounted on the main wall panel. The stack type mimeograph can print 1-8 colors, but it is usually 6 colors. Single color and multi-color printing can be carried out. For the drum printing machine, the two-sided printing can be realized by changing the transmission route of the substrate or by using the turnover roller. The printing materials can be either sheet paper, cardboard, corrugated paper and other hard materials, or roll form, such as self-adhesive paper and newspapers. The viscosity of printed materials must be measured with a viscosity cup. Strong post press processing capability The printing unit and processing function can be flexibly configured according to the needs of users. The unit type flexographic printing machine can facilitate the installation of auxiliary equipment.
