Spiral YO book printing is a product that many printing and packaging factories will produce, but each manufacturer's products will be different, the quality is good and bad, so how to distinguish the quality of Spiral YO book printing materials?

1, the surface material is the surface material, is the front can be used to print graphics, the back can withstand the adhesive and can be applied to the material to be pasted. In general, any flexible deformable material can be used as the fabric of Spiral YO book printing material, and the type of surface material depends on the final application and printing process. The surface material should be able to adapt to printing and printing, have good inking property, and have enough strength to accept a variety of processing, the surface luster and color consistency of the surface material, the uniformity of density and other indicators determine the ink absorption uniformity of the Spiral YO book printing material, and determine the color difference of the quality of the same batch of stickers.

2, the surface coating is used to change the surface characteristics of the surface material. Such as improving the surface tension, changing the color, increasing the protective layer, etc., so that it can better withstand the ink and easy to print, to avoid dirt, increase the ink adhesion and prevent the purpose of printing pictures and graphics peeling. The surface coating is mainly used for non-absorbent materials, such as aluminum foil, aluminized paper and various film materials. The coating strength of the surface material determines whether a large amount of paper powder will be produced when printing, and is also an important standard for determining the quality of printing.

3, coating the bottom layer: in fact, this is the same as the surface coating, but the coating is on the opposite side of the surface material, the main purpose of coating the bottom layer is: to protect the surface material, prevent the adhesive from soaking; Increase the lightlessness of the fabric; Increase the adhesive force between the same surface materials; Prevent the plasticizer in the plastic surface material from soaking into the adhesive, thereby affecting the adhesive function effect, resulting in the reduction of the adhesive force of the label, resulting in the loss of the sticker.
