Hello everyone, although the UV flatbed machine is convenient for our lives, there are still some big difficulties in the printing process, but these big difficulties can be prevented, teach you how to deal with the unevenness of the material when printing on the UV flatbed machine.
Why does the contour appear during the printing process of the UV flatbed printer? Due to the principle of thermal expansion and contraction of the sample material due to the heat generated by the UV lamp and heating installation during printing, the natural physical reaction is caused by the concave and the two sides of the convex. It is assumed that the unevenness will not only damage the printer nozzle but also cause the sample material to suffer. To damage, so some kind of attention should be paid.
As for how to deal with it? Here I provide you with a few ways to deal with it.
Assuming that you can never use flexible printing materials as much as possible because flexible printing materials are exposed to high temperatures, their flexibility will become softer, and it is very difficult to generate contours. Therefore, it is usually necessary to select hard materials for printing.
Alcohol is good and can be sterilized, but there is also a principle that can be used to avoid the thermal expansion and contraction of flexible materials during the printing process. Because alcohol can cool the material, it can keep the material at a certain low temperature, so that it can survive high temperatures. At that time, there is a certain degree of resistance to prevent deformation, so this is also a very common way to deal with it.
Increase the temperature settings of the UV lamp and the heating installation. The temperature of the UV lamp and the heating installation on the nozzle in the UV flat-panel machine can be adjusted. We can increase the temperature of the UV lamp and the heating installation to make The temperature not so low during printing so that the printed material will never be deformed. This also has certain limitations: the UV lamp and heating installation are used to dry the ink quickly, if it is adjusted higher, the ink will never be so difficult to dry. Therefore, when the temperature setting is lowered, the printing speed is set as a low speed to deal with this problem.
Keep the temperature of the printing space sufficiently hot, suitable for summer. Because of the hot summer, you will never feel bad when you turn on the cold air conditioner. If the air temperature and humidity are high enough, it can also resist UV light and heating. Install the function of high temperature.
