What are the functions of the back printing of self-adhesive labels?

①Back Printing. Printing a small amount of text or patterns on the surface of the adhesive to achieve the purpose of a double- label. The label is used on a transparent bottle body or glass with a transparent liquid, and the text description on the label can be clearly seen through the transparent bottle body or glass playing the role of a label on both sides. It saves label materials and costs, and also gives the commodity a special decoration effect. The sticker printing merchants found that due to the structure of the label, the label with back printing has a certain anti-counterfeiting effect.
②Back Adhesive Covering. Some labels do not need to be coated with adhesive on the back, but only partially coated. For example, the label with the characteristics of re-adhesion and removability, the part that comes into contact with finger does not need to be sticky; some labels with back cuts, the back cut part does not need to be sticky in order to easily remove the base paper. In order to the above needs, the printing factory prints ink on the position where the adhesive needs to be removed by printing, covers the adhesive, makes it not sticky, and achieves the same effect the local coating process when the raw material is manufactured.
Back printing is suitable for small batches and labels with low precision requirements. If mass production, it should be fundamentally solved the raw material manufacturing, such as back printing, the fabric back can be pre-printed, and then made into a label material. And the label with back covering, it can made into special materials by using the method of local missing coating adhesive in the material manufacturing, and use special materials to process
