不干胶印刷质量控制要注意什么?

来源:http://www.xinfengyinshua.cn/   发布时间:2022-01-21
印刷完成之后的不干胶产品,也可采用联机进行烫金、覆膜以及模切、分切等作业,而采用联机同时作业的不干胶产品版面,设计时要充分考虑到设备特点,尽量避免大面积实地版面叠印,使印刷、烫金、覆膜能获得较好的效果。烫箔工艺是不干胶产品深受市场欢迎,必不可少的一道工序。
For the self-adhesive products after printing, online bronzing, film covering, die cutting, slitting and other operations can also be adopted. For the self-adhesive product layout with online simultaneous operation, the equipment characteristics shall be fully considered in the design, and large-area field layout overprint shall be avoided as far as possible, so that the printing brush, bronzing and film covering can obtain better results. Foil ironing process is an indispensable process for self-adhesive products, which is very popular in the market.
铜版不干胶、塑料薄膜不干胶产品常常采用电化铝烫印工艺,可起到画龙点睛的作用,提高商品的附加值。但是,如果工艺不当,电化铝烫印容易出现一些质量问题,如版面发花、铝箔附着不牢、版面边沿毛刺等弊病,将会影响产品的市场形象。所以,为确保烫箔质量,底色油墨不可印得过于厚实,工艺上应尽量做到“深墨薄印”,也就是说要把油墨的色相适当调深些,使印刷墨层相应减薄一点就能达到符合原稿要求,并有利于铝箔的牢固附着,也不易产生拉脱底色墨的烫印弊病。为了使烫箔版面清晰,锌版要腐蚀得适当深一些,使烫印版面和空白部位形成一定量的高度差,以免出现空白版面起脏。
Copper plate self-adhesive and plastic film self-adhesive products often use electrochemical aluminum hot stamping process, which can make the finishing point and improve the added value of goods. However, if the process is improper, anodized hot stamping is prone to some quality problems, such as layout blooming, weak adhesion of aluminum foil, layout edge burr and other disadvantages, which will affect the market image of the product. Therefore, in order to ensure the quality of hot foil, the background ink should not be printed too thick, and the process should try to achieve "deep ink thin printing", that is, the hue of the ink should be appropriately deepened to make the printing ink layer thinner, which can meet the requirements of the original, and is conducive to the firm adhesion of aluminum foil, and it is not easy to produce the hot stamping disadvantage of pulling off the background ink. In order to make the hot foil layout clear, the zinc plate should be corroded properly to form a certain height difference between the hot stamping layout and the blank part, so as to prevent the blank layout from getting dirty.
由于烫箔压力比印刷压力要稍大些,为避免衬垫受压变形引致电化铝版面边缘毛刺产生,故衬垫应采用中硬性材料,变形系数少且平整度好,才能保证烫印效果,使整批产品质量达到一致。另外,如果烫印效果不良,出现烫印不上、发花、附着不牢等质量缺陷时,工艺操作措施上无法克制上述情况的,可考虑更换质量较好些的烫金箔,以改善烫印质量效果。

Since the foil pressing pressure is slightly higher than the printing pressure, in order to avoid the edge burr of electrochemical aluminum plate caused by the compression deformation of the liner, the liner should be made of medium hard material with less deformation coefficient and good flatness, so as to ensure the hot stamping effect and make the quality of the whole batch of products consistent. In addition, if the hot stamping effect is poor and there are quality defects such as poor hot stamping, hairiness and loose adhesion, and the above conditions cannot be restrained in the process operation measures, it can be considered to replace the hot stamping foil with better quality to improve the hot stamping quality effect.
不干胶分为纸类不干胶标签纸——通常有光面铜版纸、哑粉纸、特种纸、胶版纸、牛皮纸、铝箔纸和荧光纸等多种材质;非纸类不干胶标签材料——有PET、PE、PVC、BOPP、OPP、镭射膜、缎和无纺布等。
Self adhesive label paper is divided into paper-based self-adhesive label paper - usually made of smooth coated paper, matte paper, special paper, offset paper, kraft paper, aluminum foil paper, fluorescent paper and other materials; Non paper self-adhesive label materials include pet, PE, PVC, BOPP, OPP, laser film, satin and non-woven fabric.
不同材质的标识不干胶,在印刷工艺上,应采用与之相适应的油墨进行印刷,如非吸水性的材料,应采用合成油墨进行印刷,才能较好地确保油墨附着的牢度和干燥性。在模切上也要注意控制好相应的压力,才能保证便于使用时的撕揭。此外,不同特性的不干胶,其粘合剂的性质也有差异,如热熔胶的不干胶粘性较强,适合于粘帖在金属、玻璃、木器、塑料以及盛装可冷藏食品的容器等,在使用的过程中可以较好地避免标签出现翘角、卷边或出现脱落等不良现象。
For the identification self-adhesive of different materials, the corresponding ink shall be used for printing in the printing process. For example, for non absorbent materials, synthetic ink shall be used for printing, so as to better ensure the fastness and dryness of ink adhesion. In the die-cutting, we should also pay attention to controlling the corresponding pressure, so as to ensure the tearing and uncovering when it is easy to use. In addition, the adhesive properties of self-adhesive with different characteristics are also different. For example, the self-adhesive of hot melt adhesive has strong viscosity and is suitable for sticking to metal, glass, wood, plastic and containers containing refrigeratable food. In the process of use, it can better avoid adverse phenomena such as warping, crimping or falling off of labels.
