Why large graininess of the white ink when UV printing?

There are usually two reasons for the large graininess of the white ink of the UV flatbed printer: the quality problem of the white UV ink itself and the problem of the curve. The solution is as follows:

1. Compared with other pigment inks, the white UV ink itself has larger precipitation and ink impurities due to the addition of titanium dioxide. If the quality of the white UV ink itself is poor, on the one hand, it will speed up the clogging process of the nozzle and shorten its service life. On the other hand, there will be large graininess and ink breakage during the printing process. This requires contacting the manufacturer to replace higher quality UV ink.

2. The problem of curves

When the white ink has a large graininess, the general curve uses a larger printing curve. You can contact the printer manufacturer and send a small print curve, and this problem can be solved after replacement.

It should be noted that if the ink of the UV flatbed printer used has a stirring function, you can turn on the stirring for 5 minutes before printing. If there is no stirring function, pls manually stirs it.
