With the popularity of UV flat-panel printers in the market, anyone who has been exposed to UV printers knows that they can print on any flat material. So since UV printers can print on any flat material, can bumps be printed as well? The answer is of course not printing on concave convex surfaces. So what exactly is the original picture?

1. There is a certain distance between the nozzle and the material when the UV printer prints the pattern. Generally, the most suitable distance is 2-3 mm.

2. Concave-convex surface in the process of printing sprinkler and material collision, lightly damaged sprinkler, if serious sprinkler will be directly scrapped, so not only will affect the production schedule, but also need to pay extra maintenance costs.

Thirdly, it is not feasible to raise the nozzle so that it will not collide with this method. At this time, the ink cart will be raised, beyond the appropriate distance will lead to the printed pattern blurred picture, there will be ink phenomenon, affecting the printing effect.
