不干胶标签印刷的方式、特点有哪些?

来源:http://www.shengfengyinshua.com/ 日期:2020-06-08 发布人:shengfeng 不干胶标签印刷,也叫不干胶印刷,商标印刷,它是采用某种印刷方式将标签印制成具有自粘性的不干胶材料,印制的成品可以揭下来,黏贴于商品或包装物上对其进行标识。
Self adhesive label printing, also known as self-adhesive printing, trademark printing, it is a kind of printing method to print labels into self-adhesive materials. The printed products can be removed and pasted on commodities or packages to mark them.
印刷方式一:凸印
Printing method 1: embossing
采用凸印印刷不干胶标签,印版为感光树脂凸版,印刷标签具有墨色饱满的优点,但现在凸版印刷设备档次差别较大,有的仍在使用圆压平凸印机,有的使用普通轮转凸印机,有的已采用了的斜背式、卫星式或机组式不干胶标签印刷机,所以在转型时不能一概而论。
The self-adhesive label is used for embossing printing. The printing plate is a photosensitive resin embossing plate. The printing label has the advantages of full ink color. But now the level of the embossing printing equipment is quite different. Some of them are still using the round embossing machine, some of them are using the ordinary rotary embossing machine, some of them have used the professional inclined back, satellite or unit type self-adhesive label printing machine, so they can not be all in the transformation As a matter of fact.
印刷方式二:胶印
Printing method 2: offset printing
胶印是我国标签印刷厂印刷纸质不干胶的主要方式。胶印的特点是图文精细,层次丰富,适于大批量印刷,且印刷设备可一机多用,适合中国标签市场的特点。
Offset printing is the main way for label printing factory to print paper adhesive. Offset printing is characterized by fine graphics and text, rich layers, suitable for large-scale printing, and printing equipment can be multi-purpose, suitable for the characteristics of the Chinese label market.
印刷方式三:柔印
Printing mode 3: flexographic printing
目前柔性版印刷品的质量不亚于胶印,甚至有其独特的地方。这种印刷工艺的优点是机器结构简单,成本低,印刷质量可与胶印、凹印相媲美,且具有比胶印产品墨层厚实的优点。但由于柔性版的弹性较大,阶调再现性与凹版和普通凸版不同,柔性版印刷的高光到中间调的网点增大较大,印刷反差小,高光层次容易出现断层,在印刷精细图文标签时,为了弥补层次缺陷,高光部分可采用调频网点,暗调或中间调用调幅加网以提高质量。
At present, the quality of flexographic printing is not inferior to offset printing, and even has its unique place. This printing process has the advantages of simple machine structure, low cost, printing quality comparable to offset printing and gravure printing, and has the advantages of thicker ink layer than offset products. However, due to the flexibility of the flexographic plate, the step reproducibility is different from that of the gravure plate and the ordinary relief plate. The dot from the highlight to the middle tone of the flexographic plate increases greatly, the printing contrast is small, and the highlight level is prone to faults. When printing fine graphic labels, in order to make up for the defects of the level, the highlight part can adopt the frequency modulation dot, and the amplitude modulation plus net can be used in the dark or in the middle to improve the quality.
印刷方式四:凹印
Printing mode 4: gravure printing
凹版印刷采用短墨路输墨系统供墨,卷筒料印刷,自动化程度很高,使用溶剂型油墨,墨层干燥迅速,是薄膜类印刷的。一般凹版印刷机速度较高,许多凹版印刷机的后端还配置滚筒模切装置,可进行模切、压痕,适于各种标签的印刷。
Gravure printing adopts short ink path ink delivery system for ink supply, web printing, high degree of automation, using solvent based ink, ink layer drying quickly, is the first choice for film printing. Generally, the speed of intaglio printing machine is high, and the back end of many intaglio printing machines is also equipped with roller die-cutting device, which can be used for die-cutting and indentation, and is suitable for the printing of various labels.
