关于印刷——标签上的防伪技术,你了解多少?

FABIAOYU2018-01-08


  1. 在大众消费者的眼中,仅仅是一个可以辨别产品和分析其主要成分的工具,而在品牌商的眼中,标签对产品可以说是至关重要,它远远大于消费者所看到的表象。而在标签众多的功能中,防伪是不容忽视的一个重要功能。

      认知度较高的油墨防伪

      防伪油墨是标签防伪技术体系中的一个重要部分,防伪油墨是指具有防伪功能的油墨,同样由色料、连结料和油墨助剂组成,但在油墨连结料中加入了特殊性能的防伪材料并经特殊工艺加工而成,是特种油墨。市面上主流的防伪油墨一般有紫外荧光油墨、日光变色油墨、热敏油墨、化学反应变色油墨、水敏防伪油墨等等。用紫外荧光油墨印刷的产品,在专用的防伪荧光灯照射下,采用防伪荧光油墨印刷的标记会发亮,呈现出鲜艳的红、橘红、黄绿或绿色荧光,其荧光强度高,印刷适应性好,光亮消失也很快,在紫光灯关闭后,光亮即刻消失。日光变色油墨在日光的照射下会有字码出现。热敏油墨在加热后变色,冷却后图形又复原(如图1所示),属于可逆变色油墨。
