标签印刷的柔印印刷技术!

  作为产品形象的重要组成部分,标签的“外观层次”要求越来越高。在展望阳光明媚的日子里,对标签环保的要求越来越高,采用环保柔印生产高外观水平的标签是未来标签发展的一个重要方向。在所有柔性版印刷应用中,标签印刷比其他柔性版印刷要求更高的质量。不同印刷要求对印版的选择。

  As an important part of product image, the requirement of "appearance level" of labels is getting higher and higher. In the sunny days, the demand for environmental protection of labels is getting higher and higher. Using environmental flexo printing to produce labels with high appearance level is an important direction for the future development of labels. In all flexographic printing applications, label printing requires higher quality than other flexographic printing applications. The choice of plate for different printing requirements.

  承印材料、印版选用

  对于纸张作为标签印刷的主要承印物,客户可能不关心印刷的网点部分,而且现场要求也非常高。因此,具有中等硬度或较低硬度,同时具有良好油墨转印率的印版将更广泛地被此类用户所使用。

  For paper as the main printer of label printing, customers may be the least concerned about the dot part of printing, and the site requirements are very high. Therefore, plates with medium or low hardness and good ink transfer rate will be more widely used by such users.

  对于薄膜标签印刷来说,镜面光的逐渐变化和细网点的复制更加受到关注,因此高硬度、高分辨率和携带细网点能力的印版常常受到印刷企业的欢迎。

  For thin film label printing, the gradual change of mirror light and the replication of fine dots are more concerned, so the printing plate with high hardness, high resolution and the ability to carry fine dots is often welcomed by printing enterprises.

  油墨、印版选用

  对于不同的产品,除了广泛使用UV油墨外,油墨在食品和医药印刷中的应用也在逐步扩大。不同的柔性印版,由于印刷特性的不同,在不同的油墨体系中,可能会有完全不同的印刷性能。

  For different products, besides the extensive use of UV ink, the application of ink in food and pharmaceutical printing is also gradually expanding. Different flexographic plates may have different printing performance in different ink systems due to different printing characteristics.

  因此,在考虑柔性版印刷企业时,首先要充分了解客户和自己的情况,然后遇到问题要看本质,容易应对。与此同时,为了满足这些需求,柔版板供应商也积极发展柔性板的数量不同的印刷要求,根据这些板块的不同材料和生产方法可分为固体感光树脂溶剂版本,洗版,热的版本,橡皮雕刻板等。

  Therefore, when considering flexographic printing enterprises, first of all, we should fully understand the situation of customers and ourselves, and then when we encounter problems, we should see the essence and deal with them easily. At the same time, in order to meet these needs, flexographic vendors are also actively developing different printing requirements of flexographic plates. According to the different materials and production methods of these plates, they can be divided into solid photosensitive resin solvent version, wash version, hot version, rubber engraving board, etc.

  根据板材的不同性能选择不同的柔印材料

  首先,显示印刷板质量是我们关注的,包括镜面分支的承载能力(分辨率板),减少小文本行性能,再现能力对白色的文字和线条,网络扩张,逐步减少其中,油墨转移能力,字段和印刷性能的网络和其他因素。将直接影响板的分辨率板的图像高分辨率的图像,例如,近年来促进高清柔版印刷技术,必须选择小的分支可以稳定在12微米板,可以满足日本的需求,如高端标签印刷、制版过程本身,当然,还需要一个更精确的控制。

  Firstly, we pay more attention to the quality of printed boards, including the bearing capacity of mirror branches (resolution boards), reducing the performance of small text lines, reproducing the ability of white text and lines, expanding the network, gradually reducing the ink transfer capacity, field and printing performance of the network and other factors. For example, in recent years, in order to promote high-definition flexographic printing technology, the smallest branch must be selected to stabilize at 12 micron plate, which can meet the needs of Japan, such as high-end label printing, plate-making process itself, and of course, a more precise control is also needed.

  其次,印版在印刷过程中必须综合考虑印刷的适宜性,涉及到印版与粗糙表面材料的相容性,不同UV油墨与油墨的相容性,印版的耐久性和再利用的稳定性,将会极大地影响到生产的顺利进行。例如,在标签印刷中,在许多印刷工厂中已经出现了一种现象。印版在印刷机启动初期出现油墨转移不良的问题,但在1000m ~2000m印刷后,印刷效果逐渐恢复正常。不考虑印刷环境中的其他因素,就印版而言,这种现象往往与较差的洗涤和干燥有关。

  Secondly, the suitability of printing must be considered comprehensively in the printing process, which involves the compatibility of printing plate and rough surface materials, the compatibility of different UV ink and ink, the durability of printing plate and the stability of reuse, which will greatly affect the smooth production. For example, in label printing, a phenomenon has appeared in many printing factories. Ink transfer was not good at the beginning of printing press start-up, but the printing effect gradually returned to normal after 1000m ~ 2000m printing. Regardless of other factors in the printing environment, this phenomenon is often associated with poor washing and drying.

  版本当洗涤溶剂不平衡的问题,您的版本的组件的比例的溶剂,溶剂洗版板表面属性产生巨大影响,引起的板没有墨水,墨水转坏,当然,如果剩余的设备不能洗版溶剂去除材料表面,干燥不足条件下的同时,同样会导致这个问题。但如果能选择一种对变化不敏感的溶剂,并能快速干燥印版,这个问题就会得到解决。

  When the washing solvent is unbalanced, the proportion of solvents in your version components and the surface properties of the solvent washboard have a great impact, resulting in no ink on the board and deterioration of the ink. Of course, if the remaining equipment can not wash the solvent to remove the material surface, the problem will also be caused under the condition of insufficient drying. But if we can choose a solvent which is insensitive to change and can quickly dry the plate, this problem will be solved.

  通过以上简要分析制版技术和板材料评价方法,希望帮助标签用户选择合适的产品根据企业设备和产品目标的特点,科学、公平的评价方法,在技术和效益获得双丰收。

  Through the above brief analysis of plate making technology and plate material evaluation methods, I hope to help label users select appropriate products according to the characteristics of enterprise equipment and product objectives, scientific and fair evaluation methods, in order to achieve a double harvest in technology and efficiency.
