2、造纸用防伪球：防伪球：又称防伪微球、防伪点，产品粒径100微米-200微米，具体分为三大类：一．可见防伪球：又称有色防伪点，自然光下可见，紫外灯照射下发出各色荧光；二、不可见防伪球：又称隐形防伪球、防伪荧光球，自然光下不可见，紫外灯照射下发出各色荧光；三、复合防伪荧光球：可根据客户需要定制颜色组合。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荧光球。防伪荧光球的使用方法有两种，一是在造纸过程中将红、蓝、绿、棕色等彩色防伪球、各种防伪荧光球掺入纸浆内，二是在纸张未定型前或涂布胶水后将防伪球撒在纸张表面，在自然光或紫外灯照射下即有不同效果色光或荧光反射。anti-counterfeitmicro-bead(anti-forgerymicro-bead,anti-clonemicro-bead,authenticationmicro-bead,tracingandtrackingmicro-bead,anti-theftmicro-bead,traceabilitymicro-bead,securitymicro-bead）：Themicro-bead'sdiameterisbetween100micrometersand200micrometers.Therearethreemajortypesofthemicro-beads:1,Visiblesecuritymicro-bead(suchasred,green,blue,alsocalledvisiblemicro-bead).2,Invisiblefluorescentsecuritymicro-bead(alsocalledcolorlessUVfluorescentsecuritymicro-bead),itcanfluoresce(suchasred,green,blue)undertheultravioletlight.3,Compositesecuritymicro-bead:Therearemorethanoneanti-counterfeitfeaturesonamicro-beadwhichcanbemadebycustomer'sorder.Thepaperisusuallyusedtomakethepackagingofproducts.Sometimesthepaperofthepackagingneedtobeaddedsomeanti-counterfeitfeatures.Toaddthesecuritymicro-beadinthepaperpulpisaeffectivemethodtomaketheanti-counterfeitpaper,anothermethodistodistributethemicro-beadonthesurfaceofthepaperwhichiscoveredbytheglue.Itisverydifficulttocounterfeitthepackagingwhichismadebythepaperwithsecuritymicro-beads.（1）普通彩色防伪球：该微球可用来制作防伪纸张。该微球是有颜色的（红、蓝、绿等），混入纸浆抄纸后，自然光下观察，彩色防伪球随机分布在纸张中，用针可将微球挑出。Coloredsecuritymicro-bead:Thecolored(suchasred,green,blue)micro-beadscanbeaddedinthepaperpulptomakingthesecuritypaper.Whentheyaredistributedinthepaper,andtheycanbefoundunderthenaturallight.Themicro-beadscanbeextractedfromthepaperusingtheneedle.（2）不可见防伪球：该微球又称隐形防伪球、防伪荧光球，荧光点，可用来制作防伪纸张。该微球在自然光下为近白色，混入纸浆抄纸后，自然光下防伪球不可见，用紫外灯照射，可见随机分布在纸张中的防伪球发出荧光（红、蓝、绿等），用针可将防伪球挑出。Invisiblefluorescentsecuritymicro-bead(alsocalledcolorlessUVfluorescentsecuritymicro-bead):Themicro-beadscanbeaddedinthepaperpulptomakingthesecuritypaper.Theyarecolorless(white),whentheyaredistributedinthewh
