山东印刷中的柔版印刷技术!

  作为产品形象最重要的局部,对标签“颜值”的请求越来越高。在等待阳光绚烂的日子里,对标签环保的请求也越来越高,运用环保的柔印方式消费高颜值的标签是将来标签开展的重要方向。在一切的柔性版应用范畴里,标签印刷关于质量的请求远远高于其他柔印应用。不同的印刷需求下对印版的选择不同。

  As the most important part of product image, the requirement for label "face value" is getting higher and higher. In the days of waiting for the sunshine, the demand for environmental protection of labels is also increasing. The use of environmental flexo printing to consume high-value labels is an important direction for future label development. In all flexographic applications, the quality requirements of label printing are far higher than those of other flexographic applications. The choice of plate is different under different printing requirements.

  承印资料不同,印版选择不同

  Different printing materials and plate selection

  关于以纸张为主要承印资料的吊牌印刷,客户最关注的可能不是印品的网点局部,而对实地的请求很高。因而具有中等硬度或较低硬度,同时具有良好油墨转移率的印版会更为此类用户所普遍运用。

  With regard to hanging plate printing with paper as the main printing material, customers may not be most concerned about the dot parts of the printed products, but have a high demand for the field. Therefore, plates with medium or low hardness and good ink transfer rate will be more widely used by such users.

  对薄膜标签印刷而言,高光的突变和精密网点的再现更被关注,因而高硬度、高分辨率,可以承载精密网点的印版常常遭到印刷企业的欢送。

  For thin film label printing, the sudden change of high light and the reproduction of precise dots are more concerned, so the printing plate with high hardness and high resolution, which can carry precise dots, is often welcomed by printing enterprises.

  油墨不同,印版选择不同

  Different Ink and Printing Plate Choice

  针对不同的产品,除了普遍运用的UV油墨之外,水墨的运用在食品和药品等印刷范畴里也在逐步扩展。而不同的柔性印版,由于具有不同的印刷特性,在不同的油墨体系下,可能具有完整不同的印刷表现。

  For different products, in addition to the commonly used UV ink, the use of ink in food and pharmaceutical printing areas is also gradually expanding. Different flexographic plates may have different printing performance under different ink systems due to their different printing characteristics.

  因而,印刷企业在思索柔版时应该首先充沛理解客户和本身的条件,再遇到问题时才干看到实质轻松应对。同时,针对这些需求,柔版版材供给商也积极开发出众多针对不同印刷需求的柔性版版材,依照这些版材资料及制造方式的不同分为固体感光树脂溶剂版、水洗版、热敏版、橡皮直接雕琢印版等。

  Therefore, when considering flexography, printing enterprises should first fully understand the conditions of customers and themselves, and then only when they encounter problems can they see the substance and deal with it easily. At the same time, in response to these needs, flexographic plate suppliers have actively developed a number of flexographic plates for different printing needs. According to the different materials and manufacturing methods of these plates, they can be divided into solid photosensitive resin solvent plate, water-washed plate, heat-sensitive plate, rubber direct engraving plate and so on.

  依据版材的不同性能选择不同柔版资料

  Selection of Flexographic Materials Based on Different Properties of Plates

  首先,版材表现出的印刷质量是我们最为关注的,其中包括高光网点的承载才能(印版分辨率),细小文字线条的复原性能,反白文字和线条的再现才能,网点扩张水平,中间阶调的复原性,实地油墨转移才能,实地加网的印刷表现等要素。其中印版的分辨率会直接影响印版对高精度图像的再现,例如关于近些年推行比拟多的高清柔印技术,必需选用最小网点能够稳定到达12微米以下的印版,才干满足日化类等高端标签的印刷需求,当然制版过程自身也是需求更为精准的控制。

  First of all, the printing quality of plate material is our most concerned, including the carrying capacity of high-light dots (plate resolution), the recovery performance of fine lines, the reproduction ability of anti-white words and lines, dot expansion level, the restoration of middle tone, the transfer ability of field ink, and the printing table with field screen. Now and other elements. The resolution of the printing plate will directly affect the reproduction of high-precision images. For example, in recent years, more high-definition flexo printing technologies have been implemented. It is necessary to select the minimum dots which can stabilize the printing plate to less than 12 microns in order to meet the printing needs of high-end labels such as daily chemicals. Of course, the plate-making process itself is also more demanding. Accurate control.

  其次,印版在印刷过程中表现出的综合印刷适性也是必需要思索的,触及印版对粗糙外表材质的兼容性、对不同UV油墨和水墨的兼容性、印版的耐用水平和反复运用所表现出来的稳定性等,都会极大地影响消费的顺利停止。例如,在标签印刷中很多印厂都曾经呈现一种现象,印版在印刷机开机初期表现出油墨转移不良的问题,而经过1000~2000m的印刷后,印刷效果逐步正常。抛开印刷环境中的其他要素不谈,就印版而言,这类现象很多时分是和洗版及烘干不良相关。

  Secondly, the comprehensive printing suitability of printing plate in the printing process also needs to be considered, touching on the compatibility of printing plate with rough surface material, compatibility with different UV ink and water ink, the level of durability of printing plate and the stability of repeated use will greatly affect the smooth stop of consumption. For example, in label printing, many printing factories have presented a phenomenon, printing plate in the early start of the printing machine showed the problem of poor ink transfer, and after 1000-2000m printing, the printing effect gradually normal. Apart from other elements in the printing environment, for printing plates, this phenomenon is often associated with poor washing and drying.

  当洗版溶剂呈现失衡问题,也就是洗版溶剂的各组分比例失调时,洗版溶剂对版材外表性能产生宏大影响,形成印版不亲墨,油墨转移不良,当然假如洗版设备不能将版材外表残存的溶剂肃清掉,同时烘干不充沛的状况下,一样会形成该问题。但假如能选用一类对溶剂的变化不敏感,同时可以快速烘干的印版,这类问题就迎刃而解了。

  When the solvent of plate washing is unbalanced, that is, the proportion of each component of the solvent of plate washing is imbalanced, the solvent of plate washing has a great impact on the appearance performance of plate, forming a plate that is not ink-friendly and the transfer of ink is poor. Of course, if the plate washing equipment can not remove the residual solvent of plate appearance, while drying is not sufficient, 1. This will lead to the problem. But if we can choose a kind of printing plate which is insensitive to the change of solvent and can be quickly dried, this kind of problem will be solved.

  经过对以上制版技术和版材评价方式的扼要剖析,希望有助于标签用户经过客观、科学、公正的评判方式,依据企业设备和产品的特性选择适宜的产品,在技术和效益上取得双歉收。

  After a brief analysis of the above plate-making technology and plate evaluation methods, I hope it will help label users to select suitable products according to the characteristics of enterprise equipment and products through objective, scientific and fair evaluation methods, and achieve double failures in technology and efficiency.
