多色段防伪纤维.doc

防伪短纤维产品介绍 防伪纤维网 /多色段防伪纤维单根多色防伪纤维又称多色段防伪纤维、色谱防伪纤维、彩虹防伪纤维、断点防伪纤维，包含可见单根双色纤维、单根双色防伪纤维、单根三色防伪纤维、单根双色荧光防伪纤维、单根三色荧光防伪纤维。该纤维是由多种颜色组合的，在同一根纤维上有“红-蓝-绿、荧光红-荧光蓝-荧光绿”等多种颜色色段按规律排列，每种颜色可以是肉眼可见色，也可以是紫外荧光激发颜色等。该纤维用来制作防伪纸张，可以有效防止造假者用印刷细线的方式仿冒普通有色纤维和单根单色荧光纤维的视觉效果。由于印刷套色很难准确到微米级别，因此无法用印刷细线的方式模仿添加了该种纤维的防伪纸张。消费者可以用以下两种方法辨别：a、撕开纸张或用针挑出纤维直接观察，每一根纤维上都有多种颜色。b、两种色段交接处不会产生错位，若有错位，可判定为印刷仿冒。Multi-color fiber: The fibers are usually used to be mixed in the paper pulp to make the security paper. There are more than one color (or UV excitation color) on a single fiber. The colors and the rank of them constitute a specific character of the fiber which is designed by the customers order. Some counterfeiters print many short lines on the paper to counterfeit the single color fiber, but it is easy to differentiate the multi-color security fiber in the paper and the short line printed on the paper by means of the following methods: a. To tear the paper or to extract the fiber from the paper by using the needle, there are two(or more) colors on a fiber. b. To observe the junction of the two adjacent colors in the short line(or on the fiber) on the paper, there is no malposition or breakpoint on the fiber, but the printed short lines are different, because the print technology level is not enough to make so high accuracy prints. 所属种类：防伪短纤维：产品长度1-8毫米，直径20-200微米，通过颜色变化、颜色组合方式、变色条件、外形等特征达到防伪效果，其上的防伪特征具体有：（1）颜色及变色方式：普通彩色（自然光下可见）、无色变有色、有色变无色、有色变同色系色、有色变其他色；（2）颜色组合方式：单根单色、单根双色、单根多色、随机色谱、前后异色、正反异色等；（3）变色条件：日光、长波紫外光、短波紫外光、温度、角度等；（4）外形：圆、扁、直、弯曲、弧形、波浪等。通过在一根纤维上组合以上特征（如单根双荧光色圆弯曲防伪短纤维、正反异荧光色扁状波浪防伪短纤维、有色变无色温变荧光直扁防伪短纤维等），可设定极大的复制难度，达到良好的防伪效果。应用方法：纸张是印刷各种包装的物质基础，一些采用特殊工艺制造的专用纸具有防伪特点，在专用纸张中采用的防伪技术之一就是防伪短纤维。防伪短纤维的使用方法有三种，一是在造纸过程中将防伪短纤维掺入纸浆内，二是在纸张未定型前或涂布胶水后将防伪短纤维撒在纸张表面，三是将纤维混入胶水后涂布在纸张表面，制成的防伪纸张即有不同防伪效果。Anti-counterfeiting fiber(also called anti-forgery fiber, anti-clone fiber, authentication fiber, tracing and tracking fiber, anti-theft fiber, traceability fiber, security fiber):The fibers length is between 1 millimeter and 8 millimeters, its diameter is between 20 micrometers and 200 micrometers. It shares many anti-counterfeiting features, including its natural color , way of changing color (such as from colored to colorless, from colorless to colored ,from dark to light, etc.), combination modes of color (such as single color fiber, bicolor fiber, three-color fiber, ordered array of multi-color, different colors between the head and the tail, different colors between the front and the back, etc.), excitation condition (such as the sun light , ultraviolet light, temperature, observing angle, etc.), shape (such as round, flat, bend, straight, wavy, etc.) We can add all of the features to a fiber by the order in order to increase the difficulty of counterfeiting.The paper is usually used to make the packaging of products. Sometimes the paper of the packaging need to be added some anti-counterfeit features. To mix the security fibers in the paper pulp is a effective method of making the anti-counterfeit paper, another method is to distribute the fibers on the surface of the paper which is covered by the glue. It is very difficult to counterfeit the packaging which is made by the paper with security fibers.供应商网站：/ /地址：中国浙江省杭州市昌化路 联系人：周先生 移动电话邮箱：邮 编： 310007Site: / /Address: ChangHua road,HangZhou city, ZheJiang province, China.Contact: Mr. Zhou.
