Water stickers are fragile and too soft

Water stickers are fragile, too soft to cause loss of stickers and time extension.
(1) Fragile mainly occurs when the weather is cold. The film on the surface of the water sticker is solidified, especially when the temperature difference is large. The solution is to use about 50 degrees hot water and some softened water when soaking the water sticker.
(2) Water paper is too soft, the main reason is that water paper surface printing oil times is not enough and after printing water paper is not baked and printing time is short. The solution is to bake the water paper again at 40 ℃ for 10 minutes. If the number of times of surface oil printing is not enough, the surface oil can be added, but the surface oil sleeve is not allowed to stack
