Modular local water scarcity on the simple increase water

Dirty layout is a common phenomenon in printing, not only affects the quality of printed products, but also to the operator to bring a lot of trouble. In the printing, the reasons for the dirty on the layout are various: for example, the pressure of the relies on the printing roller is too light, the water rollers are not suitable for each other, the water roller is old, the fountain solution lacks the dampening composition, and the printing plate has Problems such as aging of the rubber roller, mechanical or electrical failure, etc., can lead to different levels of dirt on the plate. Under normal circumstances, it is not difficult to solve the problem if the plate is dirty.

We used the JS2102 double-sided offset printing machine, the symptoms are the lack of water supply in the semi-middle part of the reverse version of the water roller, resulting in partial water-reducing dirty version. After replacing Shen 80mm rubber roller and water roller velvet sleeve, and replacing the hydraulic roller oscillating frame, it will not work after many adjustments. In the absence of any other reason to find out, in order to ensure that the printing task is completed on time, we take In an emergency solution, a simple water-adding device for hanging bottles was produced. It proved to be effective after use. It not only did not affect the quality of printed products, but also was suitable for long-term use. The method is very simple, namely: find an empty hanging bottle and syringe used for hanging a needle from the hospital, fill the bottle with fountain solution, hang it on the upper part of the machine's water tank, and tie the needle tube to remove the needle at the end of the infusion tube. Then put the layer of the infusion tube on the water shortage of the string water roller and the printing plate roller, and separate it from the water by a drip method. The water requirement can be controlled by the switch of the infusion tube until the plate surface is reached. Not so dirty. This method is particularly suitable for old equipment.
