Glossy paper
Paper and coated paper says, this paper is on the base paper coating a layer of white paste made of light by pressing. Paper surface smooth, white degree is higher, the paper fiber distribution even, thickness is consistent, flexibility is small, have good flexibility and better antioxidant properties and the tensile properties of water, the printing ink absorption sex and receiving state is very good. Paper is mainly used for printing the picture album, cover, postcards, elegant product samples and color trademark, etc. Paper printing pressure when shoulds not be too big, want to choose the offset printing ink and colophony light ink. To prevent the back stick dirty, can use and prevent dirty agent, powder spraying method, etc. Paper have single, double two kinds.
