How To Deal With Uneven Printing On UV Tablet Printers?

Although UV printers have made our daily lives more convenient, there are still some difficulties in many printing processes. Most technical difficulties can be avoided, but many times we encounter the problem of uneven printing materials. Why does the contour of the UV printer appear uneven during the printing process? Because the heat from the UV lamp and heating device causes the material to expand and contract during printing, Forming a natural physical reaction where the concave and convex sides protrude, assuming this concavity is not treated, it will not only damage the printer nozzle, but also cause material damage. Therefore, it is important to pay attention to this phenomenon. How should we deal with this phenomenon?
1. If you have the ability, try to avoid using flexible printing materials as much as possible, because flexible materials can be subjected to high temperatures, which increases their flexibility and makes it difficult to make the printing contour flat. Therefore, choose hard materials as much as possible;
2. Alcohol can disinfect, but there is also a principle that can be used to avoid thermal expansion and contraction of flexible materials during the printing process. Alcohol can cool the material, so the material can adhere to a certain degree of low temperature, so that the material will not deform;
3. Set the UV lamp for heating installation, increase the temperature of the UV lamp, and adjust the temperature of the UV bulb above the nozzle to the heating installation. By increasing the temperature of the UV lamp and heating device, the printing material will not deform. However, this also has certain limitations. The UV lamp and heating device are used to quickly dry ink, and if set too high, the ink will not be so difficult to dry. Therefore, while adjusting the low temperature setting, Setting the printing speed to low speed can effectively solve this problem;
4. Control the temperature of the printing space to a sufficiently high temperature, which is mainly suitable for summer, because the weather in summer is usually hot, and turning on cold air will not feel good. If the air temperature is high enough, it can be used to resist high temperatures;
