Precautions and Reasons for Uneven Printing Before Using Double-Sided Offset Printing Machine

Considerations before using a double-sided offset printing machine

A double-sided offset printing machine is different from a regular offset printing machine in that it can achieve double-sided printing at the same time. Although it can bring us a lot of convenience, there are still several issues to consider before using a double-sided offset printing machine:

• What type of binding should be used for the double-sided offset printing machine;

• How to enable double-sided printing on the double-sided offset printing machine;
  

• What size and requirements for the metal plate should be used in the double-sided offset printing machine.
  

Double-sided offset printing machines usually have multiple printing units, with operation devices set between these units. This facility can switch the printed sheets to the other side, allowing the remaining units to print on the other side. Preparation work must be done before use to achieve a smooth printing experience and meet our requirements.

Causes of uneven double-sided offset printing machine printing

A double-sided offset printing machine was developed based on traditional offset printing machines, providing more possibilities for the diversity of printed products and modern office work. Uneven printing is one of the common problems of a double-sided offset printing machine. To solve this problem, offset printing machine manufacturers can consider the following methods:

The uneven ink of a double-sided offset printing machine during printing may be caused by inconsistent concentration of the solution used. If the ratio is not accurate, uneven printing can easily affect printing results. In the modulation process, if the concentration of the solution is relatively high, it can also cause uneven printing of the double-sided offset printing machine, as ink will flow unevenly.

In this case, the oxide on the printing roller can be removed first before roller movement to alleviate the problem. Of course, sometimes the problem may lie in the ink roller. The pressure on the ink roller during inking needs to be properly adjusted. If the adjustment is not done properly, it is more likely that uneven ink will occur. In this situation, the pressure on the ink roller can be gradually adjusted to obtain better printing results for the double-sided offset printing machine.
