In order to print the relief feel when the UV printer is printing, it is necessary to make the relief spot color layer in the PS software, add white ink jet printing in the print control software, and modify the thickness of the white background to 3 ~ 4, so that the UV printer can print the relief effect 3 ~ 4 times at the relief position, while the high-speed rotary machine can print the relief effect at one time only by modifying the value in the color management tool.

The relief effect not only has the three-dimensional feeling of carving, but also has uneven hand feeling. According to the existing printing technology, only UV flat-panel printer can complete the relief effect, and Fengda UV flat-panel printer can print the three-dimensional relief effect of mobile phone shell.
