Some issues affecting overprinting of electronic shaft printers

The principle of the electronic axis printing machine is just the opposite of the old-fashioned axis printing machine. The old printing press is a constant version, and the ball screw is used to adjust the length of the color group to achieve overprinting effect. The electronic axis printing machine needs to go through each color group. The tension is constant, and the overprint effect is achieved by changing the motor speed of each color group, that is, changing the phase of the version.

The situation of overprinting is related to the following issues:

1. Imprinting pressure 2. Embossing roller 3. Air volume of bellows 4. Air volume of air inlet

Because it is the change of the phase to achieve the correct printing effect, so the pressure of the embossing roller is as small as possible without affecting the printing effect. The imprinting pressure of several color groups is also as good as possible.

The rubber wheel should be chosen to be as wide as the printing material, so as to avoid the appearance of long-run rubber rollers and the heat generated by the printing plate, which will cause the unsteadiness of the material and affect overprinting. Overprinting.

If you are using a gas heating structure, you must pay attention to the gas flow rate of the gas furnace should be constant, to avoid large and small, which will seriously affect overprinting. Electric heating will not compare this phenomenon.
