If you want to prevent the phenomenon of color mixing in the printing machine, pay attention to leveling the pressure of water and ink roller and paying attention to the pH value of the fountain solution during the printing process. If you do not pay attention to the ink balance during the printing process, if the ink imbalance occurs, stay in the ink. The ink on the printing printing roller will also increase accordingly, which in turn increases the diameter of the printing rubber roller, which increases the pressure between the printing rollers, which causes the printing rubber roller to heat up, and the ink becomes more and more The easier it is to dry, the more the viscosity of the ink will increase, and the color mixing will occur, so the ink balance is also important.
In addition, it is also necessary to prevent the dirty plates on both sides of the printing plate, because once the blank portions of the two sides are dirty, they are transferred to the blanket and the impression cylinder, and then transferred to the ink rollers of the other group, thereby causing color mixing. When making plates, the signal strips and color patches are also printed on the plate. When the printing is normal, it can be removed to effectively prevent the printer from mixing.
