1, roller heating

If the temperature exceeds 25 degrees Celsius, the most obvious phenomenon is that the viscosity of the ink is lowered, so that the workpiece with a large amount of ink is easy to be dirty and easy to paste.

2, affecting ink and water balance

When the temperature is high, the viscosity of the ink becomes small, which tends to cause the blank portion of the printing plate to be dirty, and the dots in the large ink are easily pasted together, and the printed matter is easy to be dirty.

3, the ink is easy to dry

4, paper is easy to deform

Due to the high temperature, the moisture in the cut paper evaporates quickly, and after printing one side, since the printing back needs to wait for a certain printing cycle, the water in the paper evaporates quickly, and it is easy to cause "flank" around the paper, thereby When the back side is printed, the "corner angle" and the overprinting are not allowed, which is not conducive to the normal operation of the map printing work.
