Features: printing and processing of self-adhesive labels

1. The consistency of the surface gloss, color and density of the surface material determines the uniformity of the ink absorption of the self-adhesive material, and also determines the same batch of label printing. chromatic aberration. The coating strength of the surface material determines whether a large amount of paper powder will be produced during printing, and it is also an important indicator for determining the printing quality.

2. The uniformity and strength indication of the thickness of the backing paper and the face material are not only related to the printing performance, but also determine the importance of the die-cutting uniformity and the speed of the waste discharge and the edge breakage. indicators, if these indicators are too low, the labelling machine cannot produce at high speed.

3. The flatness of the material or the uniformity of the rewinding tension Whether it is sheet-fed printing or roll printing, the flatness of the material determines whether the paper can be fed correctly during printing , run and register, delivery. For the roll material, the rewinding tension plays an important role in the flatness of the end face of the roll material, whether there is glue leakage, and whether it can be properly registered.

4. The uniformity of adhesive and silicone oil coating and the correct coating amount affect the peeling force (release force) between the self-adhesive sticker printing and the backing paper, The size of the peeling force directly affects the speed of the die-cutting waste and the machine. The peeling force also determines the label's out-of-label status, that is, the application. In addition, the amount of glue applied will also affect the glue penetration of the end face of the material. Therefore, when purchasing self-adhesive sticker printing materials, you should carefully inspect them and choose materials with the appropriate amount of glue and silicon.
