不干膠防偽標簽印刷,不干膠標簽質量怎么查看是否合格?

來源:http://tjanamera.com/ 日期:2021-01-06 發布人:shengfeng 一、原質料的選擇
1、 Selection of raw materials
選擇原質料時,肯定要選用高質量、各項理化指標均合格的不干膠質料,而不要選用逾期或理化指標不穩固的產品。因為后者雖然價錢低,但由于這類質料質量不穩固,在各工序斲喪大,以致導致設置裝備部署無法正常加工,在浪費了原質料的同時還浪費了大量的人力、物力,效果成品標簽的加工成本并不肯定低,更為告急的是另有大概遭到客戶退貨,以致失去客戶。
When selecting raw materials, we must choose high-quality self-adhesive materials with qualified physical and chemical indexes instead of products with overdue or unstable physical and chemical indexes. Although the price of the latter is low, due to the unstable quality of such materials and the large consumption in each process, the equipment deployment can not be processed normally. As a result, a lot of manpower and material resources are wasted while the raw materials are wasted. As a result, the processing cost of the finished product label is not low. What's more urgent is that it may be returned by the customer, resulting in the loss of the customer.
原質料的選擇應從以下兩個方面思量。
The selection of raw materials should be considered from the following two aspects.
1.不干膠質料的印刷和加工特性
1. Printing and processing characteristics of self-adhesive materials
①面材的外貌毫光和顏色的同等性、密度的勻稱性
① The uniformity of appearance, color and density
達些指標決定了不干膠質料吸墨的勻稱性,還決定著同批標簽印品的色差。面材的涂層強度決定了印刷時是否會孕育發生大量紙粉,也是決定印刷質量的告急指標。

To achieve these indicators determines the uniformity of ink absorption of self-adhesive materials, but also determines 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 urgent index to determine the printing quality.
②底紙、面材厚度的勻稱性和強度指示
② Thickness uniformity and strength indication of base paper and surface material
這些指標不但關連到印刷性能,照舊決定模切勻稱性和排廢時速度與紙邊斷裂的告急指標。要是這些指標太低,標簽機就無*速生產。
These indicators are not only related to the printing performance, but also determine the die-cutting uniformity and waste discharge speed and edge fracture. If these indicators are too low, the label machine will have no * speed production.
③質料的平整度或復卷張力的勻稱性
③ Evenness of material or evenness of rewinding tension
無論是單張印刷照舊卷筒印刷,質料的平整度都決定了印刷時是否能準確輸紙、運行和套準、收紙。搪塞卷筒質料,復卷張力會對卷筒質料端面的平整度、是否出現滲膠、能否準確套準起告急的作用。
Whether it is sheet fed printing or web printing, the flatness of the material determines whether the paper can be accurately fed, run, register and received. The rewinding tension will have an urgent effect on the flatness of the end face of the reel material, whether there is glue leakage, and whether it can be accurately set.
④粘合劑、硅油涂布的勻稱性和準確的涂布量
④ Adhesive, silicone oil coating uniformity and accurate coating amount
這些指標直按影響標簽同底紙間的剝離力(離型力),而剝離力的大小又直接影響模切排廢和呆板的速度,剝離力還決定了標簽的出標狀態,即應用情況。另外,涂膠量的大小還會影響質料端面的滲膠狀態。以是,購置不干膠質料時要認真檢驗,選擇那些涂膠量和涂硅量符合的質料。
These indicators directly affect the stripping force (release force) between the label and the backing paper, and the size of the stripping force directly affects the speed of die-cutting waste discharge and mechanical, and the stripping force also determines the label's out state, that is, the application situation. In addition, the amount of glue will also affect the end of the material infiltration state. Therefore, the purchase of self-adhesive materials should be carefully tested, choose those coating amount and silicon coating amount of material.
