一种光致发光防伪油墨的研制及其应用_印刷工程专业论文 摘 要 近年来,随着我国经济的迅猛发展,人民的生活水平发生了翻天覆地的变化。但随之而来的,是商品造假行为也日趋猖獗,广大厂商的经济利益蒙受了巨大的损失,其信誉经受了前所未有的考验。为了保护广大企业及消费者的合法权益,制造厂商运用了多种防伪技术。防伪油墨即为其中极为重要的一种防伪手段。 防伪油墨技术是一种传统的防伪技术,本研究查阅了大量文献资料,用多种发光粉,包括普通发光粉和新型长余辉光致发光粉末作为颜料,通过加入UV连接料及各种辅料等,制备了一种光致发光防伪油墨样品。制备完成后,通过对样品进行细度、粘性、粘度、耐磨性等参数的测试,知道了油墨各组分对油墨主要性能的影响,并以此为基础设计配方,确定了较为理想的光致发光油墨的配比。本研究还将此油墨用于实际印刷,检测效果,并采用多种普通纸与特种纸搭配印刷,与印刷材料防伪结合,不仅增加了伪造难度,也让防伪油墨有更多的表现效果,最终取得了较好防伪效果。 关键词:光致发光,防伪,UV,丝网印刷 ABSTRACT In recent years, with the world’s economic development quickly, people’s living standard had changed very much. However, The product counterfeiting has become rampant behavior in the same time. The majority of manufacturers suffered huge losses. The reputation of manufactures suffered an unprecedented challenge. In order to protect the legal rights and interests of enterprises and consumers, manufacturers take many kinds of anti-counterfeiting technology. Counterfeiting ink is one of the most important means. Anti-counterfeiting technology is a traditional anti-counterfeiting method. This study had consult a large amount of literature, with two kinds of photoluminescence powder, including common photoluminescence powder and a new style long afterglow photoluminescence powder as the pigment, then blend some UV vincula and other assistant material and so on, preparation a photoluminescence anti-counterfeiting ink sample. After the preparation accomplish, we will have professional test of the ink sample, then know the connection of material to main performance, and based with this information, we ensured the appropriate composition rate of the photoluminescence ink. This study also put the ink to printing to test the practicality. This ink take screen print for application for test .We using a variety of general and specialty papers, combine with printing materials, not only increased the difficulty of counterfeiting, but also let the anti-counterfeiting ink have more manner for use, and get a better anti-counterfeiting effectiveness.
