The Characteristics of Sticker Printing

The particularity of sticker printing. The narrow width flexographic printing equipment has outstanding characteristics compared with embossing and other types of flexographic printing equipment. The narrow width flexographic printing equipment is not only simple to operate, but also has high quality and efficiency of sticker printing
Due to the particularity of sticker printing, the narrow width flexographic printing equipment has outstanding characteristics compared with embossing and other types of flexographic printing equipment. The narrow width flexographic printing equipment is not only simple to operate, but also has high quality and efficiency of sticker printing, strong combination, and can make more kinds of products, with more competitive strength.
1. The surface gloss, color consistency and density uniformity of the surface material determine the ink absorption uniformity of the self-adhesive material, as well as the color difference of the same batch of label prints. The coating strength of surface material determines whether a large amount of paper powder will be produced during printing, which is also an important indicator to determine the printing quality.
2. The thickness uniformity and strength indication of base paper and surface material are not only related to the printing performance, but also important indicators that determine the die cutting uniformity, waste discharge speed and paper edge fracture. If these indicators are too low, the label machine cannot produce at high speed.
3. The flatness of materials or the evenness of rewinding tension, whether single sheet printing or roll printing, determines whether the paper can be fed, run, registered and received correctly during printing. For the reel material, the rewinding tension will play an important role in the flatness of the end face of the reel material, whether there is glue seepage, and whether it can be correctly registered.
4. The uniformity of the coating of adhesives and silicone oil and the correct amount of coating affect the peel force (release force) between the sticker printing and the backing paper, and the size of the peel force directly affects the speed of the die cutting waste discharge and the machine. The peel force also determines the labeling situation of the label, that is, the application situation. In addition, the amount of glue will also affect the glue penetration of the material end face. Therefore, when purchasing self-adhesive sticker printing materials, it is necessary to carefully check and select those materials with appropriate amount of glue and silicon coating.
