Temperature control directly affects the quality of the print, learn about the many ways to adjust the temperature during the printing process

A large part of the transmission power of an offset press is used to drive the inking un.

How to adjust the temperature of the inking unit:

①The water temperature in the central water tank of the constant temperature equipment is used as the adjustment amount;

②The surface temperature of each inking device is used as the adjustment amount;

③ The water temperature injected into each inking device for the constant temperature of the ink roller is used as the adjustment amou.

The method of maintaining the constant temperature of the inking unit:

(1) Oil cooling

Although the thermal power generated by the transmission mechanism and bearing on the transmission side of the offset printing press is not large, this part of the heat is difficult to discharge, which will cause the side parts to generate he.

(2) Cooling of fountain solution

Generally speaking, we generally use a fountain solution with a temperature of about 10 °C as the coolant for the water film or alcohol wetting devi.

(3) Constant temperature of printing plate cylinder

Since waterless offset printing lacks the cooling effect of fountain solution, for waterless offset printing presses without constant temperature of inking device, it is best to cool the printing plate cylinder by blowing air, while offset printing with water only needs inki.

(4) Infrared temperature sensor

The surface of all heating bodies emits infrared rays, which can be measured by sensitive radiation detectors and displayed as temperatu.
