  • What Determines the Quality of a Flexographic Printing Plate? 21-04-22

    The flexographic printing plate can be considered the heart of flexographic printing as it has a decisive influence on the print results and productivity of the label printer. There are more than 40 flexographic printing plates for label printers on the market, but they all have different characteristics, printing behaviour and manufacturing processes. As a result, label printers are often faced with the extremely difficult task of selecting the right plate. With this in mind, Gallus spent several weeks studying and comparing the printing characteristics of all the top flexo printing plates. The results and evaluations ranged from the unusual to the unusable. Even if the perfect flexographic plate is not available in all areas, it is possible to identify a small number of top plates for the label press. The basics Most flexographic printing plates are now made of photosensitive polymers. Much fewer plates are made from rubber. The process of developing photopolymer printing plates involves the use of solvents, water and heat development. Most photopolymer aniline printing plates are washed off with solvents or water. Flat top dot In the printing plate industry, there is a current trend towards flat-top dot technology. The dots on these plates are flat at the top rather than rounded, which results in more consistent and accurate print results. "Conventional" digitally exposed photopolymer flexo printing plates usually have rounded printing dots. This is due to the presence of oxygen, which negatively affects the polymerisation of the photopolymer during UV exposure, causing the dots to shrink. The oxygen disrupts the polymerisation of the photopolymer, resulting in a rounded dot on top. Screening out the oxygen allows for the desired polymerisation, resulting in a flat-topped dot. There are several ways to remove destructive oxygen from the exposure process.  Four options used by plate manufacturers are listed below. 1.Laminated laser imaging films prevent direct contact with oxygen during UV-A exposure. 2.Film (laminate) is laminated to LAMS and prevents direct contact with oxygen during UV-A exposure. 3.Pre-exposure with UV-LED removes oxygen while polymerising the upper plate layer. 4.During a conventional UV-A exposure, the plate is filled with an inert gas (nitrogen) to displace oxygen. What determines the quality of a flexographic plate? All presses have their own specific requirements for flexographic printing plates. While one may be focused on very fast production times, another may only be concerned with print quality. Others may place great importance on the ecological aspects. Generally speaking, pre-press and plate handling have a strong influence on the printing result. However, the most influential factor is the plate, which is predetermined and cannot be changed by the user. During the print tests conducted, aniline printing plates from top manufacturers were printed, checked and compared under identical conditions. These test...

  • Advantages of Flexographic Printing 21-04-22

    柔版印刷仍然是标签行业中最常用的打印过程。没有适当的印版,因此没有适当的制版设备,就不会有柔印标签。行业领导者紧贴潮流,确保标签以最快的时间和最高的质量打印。 使用柔性板完成印刷,该柔性板最初由天然橡胶制成,然后由合成橡胶制成,现在主要由光敏聚合物制成。 柔版印刷在纸张,纸板或塑料薄膜上完成。低粘度液体油墨用于印刷。这些包括水基油墨,溶剂和紫外线(UV)固化油墨。非吸收性基材(薄膜)主要使用UV和溶剂型油墨进行印刷,但是由于其生态方面和适应性的提高,越来越多地使用水性油墨。 柔版印刷 柔版印刷或柔版印刷是一种使用柔性凸版进行批量印刷的技术。制造商首先将墨水施加到印版上,然后再施加到表面上。这是一种低成本的打印方法,自从1970年引入直接激光雕刻以来,它已经取得了很大进步。 平版印刷或平版印刷是一种印刷方法,最初是基于油和水的不可混合材料。平版印刷术可用于需要鲜艳色彩并大量印刷的任何事物。 但是,您正在使用的打印方法不仅需要实用而且要具有成本效益。对于定制印刷而言,柔版印刷与平版印刷是一个由来已久的争论,因为这是印刷和包装行业中的常规方法。 但是,当我们谈论瓦楞纸箱时,我们还是需要散装的。批量打印是一项繁琐的任务,并且需要某种程度的优化。诸如手头的预算,时间限制,打印质量以及如何使用盒子(运输或零售)等因素都在起作用。 印刷工艺 柔版印刷需要初始设置成本。Flexo使用安装在圆柱体上的柔性板。制造商使用部分浸入的墨辊将墨施加到网纹辊上。网纹传墨辊是一个硬圆柱,通常由钢或铝制成,带有陶瓷外层,并带有许多凹坑。制造商使用网纹辊将油墨均匀地分布在柔版印刷板上。 在柔版印刷过程中,通过与凹版滚筒类似的,具有均匀分布的单元(尺寸,形状和深度)的铬或陶瓷雕刻/蚀刻辊,将油墨计量到板的表面上。该辊称为“ anilox”。 瓦楞纸板直接在压印滚筒和油漆辊之间运行。最后,制造商将基材穿过干燥机以防止弄脏。 柔版印刷可用于从食品包装纸到辅助容器的所有物品,例如谷物盒到运输纸箱。柔性版印刷板上的可光聚合材料在曝光时会发生交联并捕获图像。曝光后,将苯胺印刷版浸入溶剂中以除去未聚合的材料。显影或冲洗溶剂通常是氯,饱和环状或无环烃的混合物。二甲苯是最常见的溶剂。

  • Flexographic Product Packaging Design 21-03-23

    Digital flexographic printing is a plate making technology that uses a laser to directly expose the flexographic photosensitive polymer plates. It has the following advantages. Advantages of digital flexographic printing  ①The process is simple and the preparation time is greatly reduced. ②Exposure time is independent of pattern type and dot density. ③Replacing the separation sheet with shaded metameric material eliminates the dot distortion caused by the separation sheet processing. ④The main exposure, there is no diffuse reflection of light caused by the phenomenon of dot gain, you can get a clear dot. ⑤ Realization of direct plate making without soft film, the layout will not be flooded with dirty spots and defective. From the characteristics of the digital flexographic printing plate , digital flexographic printing plate can obtain fine, clear and high quality flexo plates. Therefore, in order to improve the quality of flexo printing, the use of digital flexographic printing plate is imperative. In order to make the designed products meet the printing requirements, flexographic product packaging design staff should pay attention to the following points when designing. 1. In the use of color, should be as simple, bright, bright colors If the design of the product overprinting too many colors, will cause the color dim. Due to the larger amount of flexo printing dot expansion, small dot loss is more serious, the pattern in a certain area overprinted color version too much, each color version of the problem of dot expansion or loss, dot expansion or extinction network phenomenon will be repeatedly flooded, making the picture dim, the lack of highlights and the middle tone sector, dot transition uneven, very disgraceful. Therefore, in the same full expression of the design of the draft conditions, should be as far as possible to reduce the number of printed colors to a minimum, which is very beneficial for the bulk production of printing manipulation, quality control and cost control. 2. Try to use spot colors to make up for the lack of four-color printing Many customers of packaging products always ask the design staff in the design of their products made of yellow, magenta, cyan, black four colors overprinted more than ten colors of the manuscript, but sometimes not only through the three primary colors or conventional four colors can simply show the entire color world, additional ports with a spot color long and short necessary, but also long and short an effective method. One-sided exaggerated overprinting overlay color is not desirable. Flexographic printing machine is ideal for printing large areas of the field and spot colors, flexographic printing machine mostly six or eight colors, only four colors will cause the unit idle, and four-color printing effect than offset or gravure, affecting the quality of flexographic products. 3. Should not use too fine lines and too smal...
