不干胶材料的印刷和加工特性介绍

来源:http://www.shengfengyinshua.com/ 日期:2021-04-20 发布人:admin ①面材的表面光泽和颜色的一致性、密度的均匀性
① The consistency of surface gloss, color and density of surface materials
这些指标决定了不干胶材料吸墨的均匀性,还决定着同批标签印品的色差。面材的涂层强度决定了印刷时是否会产生大量纸粉,也是决定印刷质量的重要指标。
These indicators determine the uniformity of ink absorption of self-adhesive materials, and also determine the color difference of the same batch of label printing products. The coating strength of surface material determines whether a large amount of paper powder will be produced during printing, and it is also an important index to determine the printing quality.
②底纸、面材厚度的均匀性和强度指示
② Thickness uniformity and strength indication of base paper and surface material
这些指标不仅关系到印刷性能,还是决定模切均匀性和排废时速度与纸边断裂的重要指标。
These indexes are not only related to the printing performance, but also determine the die-cutting uniformity, waste discharge speed and edge fracture.

③材料的平整度与复卷张力的均匀性
③ Flatness of material and uniformity of rewinding tension
无论是单张印刷还是卷筒印刷,材料的平整度都决定了印刷时是否能正确输纸、运行和套准、收纸。对于卷筒材料,复卷张力会对卷筒材料端面的平整度、是否出现渗胶、能否正确套准起重要的作用。
Whether it is sheet fed printing or web printing, the flatness of the material determines whether the paper can be correctly fed, run, register and received. For the drum material, the rewinding tension will play an important role in the flatness of the end face of the drum material, whether there is glue leakage, and whether it can be correctly aligned.
④粘合剂、硅油涂布的均匀性和正确的涂布量
④ Adhesive, silicone oil coating uniformity and the correct amount of coating
这些指标直接影响标签同底纸间的剥离力(离型力),而剥离力的大小又直接影响模切排废和机器的速度,剥离力还决定了标签的出标状况,即应用情况。此外,涂胶量的大小还会影响材料端面的渗胶状况。所以,购买不干胶材料时要认真检验,选择那些涂胶量和涂硅量合适的材料。
These indicators directly affect the stripping force (release force) between the label and the backing paper, and the size of the stripping force has a direct impact on the die-cutting waste discharge and the speed of the machine. The stripping force also determines the label status, that is, the application situation. In addition, the amount of glue will also affect the penetration of the material end face. Therefore, the purchase of self-adhesive materials to carefully test, choose those gelatinization and silicon coating amount of appropriate materials.
