1, adhesive edge adhesion, bottom paper coating silicon. Adhesive edge adhesion or partial coating of silicone oil on the bottom paper will cause the paper to break when discharged and cannot be produced normally during the printing process.
2. Reel self-adhesive material cuts the end face straight and the rewinder elasticity is inconsistent. If the roll-cut adhesive material is not evenly cut, it will not only affect the registration at the time of printing, but also cause difficulties in waste disposal due to the change in the cutting position; the inconsistent elasticity during rewinding will cause the paper force during printing. Variations and uneven tension can also cause print quality problems.
3. The adhesive material has burrs, and the edge of the adhesive tape material is clean and free of damage, which is the basis for ensuring the quality of adhesive label printing. Therefore, the score of adhesive tape must be carefully checked before printing. Whether the cut edge has flashed edges.
4, there is a crack on the adhesive material. When the self-adhesive material is cut, if the cutting knife is not adjusted properly or the cutting edge is not sharp enough, cracks will appear on the surface of the adhesive material or the bottom paper, and the fibers pulled out from the cracks will be adhered by the adhesive. live.
