The best way to keep the quality of the print pattern is to use the right ink and protect well after printing. But it will also fade if exposed to ultraviolet light and ordinary incandescent light. Therefore, if you want to maintain the UV printer's printing pattern without fading, you should do the following two points:
1.The use of good sealing ink, which is the basic condition to ensure printing pattern does not fade for long time.
2.Place the printed pattern in a cool, non glare place to ensure that the pattern is not exposed to glare.
