1. Wear degree

That is, the use frequency and daily wear of the product itself. Such as frequently used mobile phone cases, key chains, wallets, and electronic product housings., It will inevitably cause certain wear and tear under daily conditions. The persistence of color can last for one to two years. Of course, this does not completely fade, but to a certain extent leads to wear and discoloration. On the contrary, if the product is not used frequently, its durability will be appropriately extended. For example, products with low indoor wear and tear, such as ceramic tile background walls, art glass partitions, glass portraits, cabinet doors, etc., can last for five to eight years;

2. Use environment

This is somewhat similar to the above. For example, the color persistence of outdoor billboards and signboards. It can last for one to two years. If wood products are exposed outdoors for a long time, their durability may be further reduced. It is not difficult to see that the persistence of color has a great relationship with the use environment of the product;

It is not difficult to see from the above that the color persistence of UV flat-panel printers can basically last for 1-8 years, but the decisive factor is the use mode and environment of the products.
