不干胶标签印刷的质量控制有哪些?

来源:http://www.shengfengyinshua.com/ 日期:2020-05-18 发布人:admin 选择原材料时,一定要选用高质量、各项理化指标均合格的不干胶材料,而不要选用过期或理化指标不稳定的产品。因为后者虽然价格低,但由于这类材料质量不稳定,在各工序消耗大,甚至导致设备无法正常加工,在浪费了原材料的同时还浪费了大量的人力、物力,结果成品标签的加工成本并不一定低,更为严重的是还有可能遭到客户退货,甚至失去客户。
When selecting raw materials, it is necessary to select high-quality self-adhesive materials with qualified physical and chemical indexes, rather than products with expired or unstable physical and chemical indexes. Although the price of the latter is low, due to the unstable quality of this kind of material, it consumes a lot in each process, and even leads to the failure of normal processing of the equipment. It wastes a lot of manpower and material resources while wasting raw materials. As a result, the processing cost of the finished product label is not necessarily low. What's more, it may be returned by customers or even lost customers.
不干胶材料的印刷和加工特性
Printing and processing characteristics of self-adhesive materials
①面材的表面光泽和颜色的一致性、密度的均匀性
① Uniformity of surface luster, color and density of surface material
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 ink absorption uniformity of self-adhesive materials, and also determine 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, and it is also an important indicator of 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 to the uniformity of die cutting, the speed of waste discharge and the edge fracture.
③材料的平整度或复卷张力的均匀性
③ Evenness of material or evenness 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 single sheet printing or web printing, the flatness of the material determines whether it can correctly feed, run, register and receive paper during printing. For the drum material, 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 the correct registration can be achieved.
④粘合剂、硅油涂布的均匀性和正确的涂布量

④ Uniformity and correct application amount of adhesive and silicone oil
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 indexes have a direct impact on the peeling off force (parting force) between the label and the backing paper, while the size of the peeling off force has a direct impact on the die cutting waste discharge and the speed of the machine. The peeling off force also determines the label's marking out status, that is, the application situation. In addition, the size of the glue will also affect the cementation of the material end face. Therefore, when purchasing self-adhesive materials, we should carefully check and select those materials with the appropriate amount of glue and silicon.
02油墨的选择
02 ink selection
选择油墨主要从油墨的自身质量、色相以及油墨对承印物的润湿情况——即油墨的附着牢度等几个方面来考虑。不干胶材料尽管种类很多,但其面材基本上可分为纸张、铝箔、薄膜三大类型。目前在我国,不干胶标签的印刷主要以凸印(卷筒印刷)和胶印(单张印刷)为主,其中凸印和胶印又分为普通树脂油墨印刷和UV油墨印刷。
The selection of ink mainly from the ink quality, color and ink on the substrate wetting situation - that is, ink adhesion fastness and other aspects to consider. Although there are many kinds of self-adhesive materials, their surface materials can be basically divided into three types: paper, aluminum foil and film. At present, in our country, the printing of self-adhesive label is mainly convex printing (roll printing) and offset printing (sheet printing). Among them, convex printing and offset printing are divided into common resin ink printing and UV ink printing.
一般纸张类面材由于基本不存在油墨附着牢度问题,故对油墨的要求不高,不同品牌的油墨有一定的互换性和通用性。但是,铝箔和薄膜类材料,由于受表面张力和不同物性的影响,对油墨的要求非常严格,选择油墨时要遵循以下原则:
Generally, there is no ink adhesion problem for paper surface materials, so the ink requirements are not high. Different brands of ink have certain interchangeability and versatility. However, due to the influence of surface tension and different physical properties, aluminum foil and film materials have very strict requirements on ink. The following principles should be followed when selecting ink:
①一种不干胶材料一次只能使用一家油墨供应商生产的油墨,不能同时混合使用其它厂家生产的同类油墨。
① One kind of self-adhesive material can only use the ink produced by one ink supplier at a time, and cannot mix the same kind of ink produced by other manufacturers at the same time.
②每一种不干胶材料原则上只能使用与其匹配的,相对应的油墨。
② In principle, each kind of self-adhesive material can only use the matching ink.
③使用的添加剂要同油墨配套,不能用其它类型的添加剂替代。
③ The additives used shall be matched with the ink and cannot be replaced by other types of additives.
④要注意油墨的使用期限,严禁使用过期油墨。
④ Pay attention to the service life of the ink. It is strictly prohibited to use expired ink.
