| 1. of the surface of surface gloss and color consistency, density uniformity: determines the uniformity of ink sticker material, but also determines the color of the same batch label printing The strength of the surface coating determines whether a large amount of paper powder is produced during printing, and also an important indicator of the quality of the printing. 2., paper, surface thickness uniformity and strength instructions: stickers not only relates to the printing performance, or determine the die uniformity and waste when the speed and the edge of the paper broken important index. If these indicators are too low, labeling machines can not speed up production. 3. evenness of material or rewinding tension: whether sheet printing or reel printing, the smoothness of the material determines whether or not the paper can be correctly transferred, run and bind properly and receive paper when printing. For reel materials, rewinding tension will play an important role in the smoothness of the end surface of the reel material, whether the glue is infiltrated or correct. 4. adhesives, silicone coating uniformity and correct coating weight: effect of peeling force with the label backing sheet (from the type of force), and the peel strength has direct effect on the size of cutting exhaust and the speed of the machine, stripping force also determines the standard label, namely application. In addition, the amount of coating will affect the end of the glue. Therefore, the purchase of self-adhesive materials should be carefully checked, the choice of the amount of coating and coating of silicon suitable material |
