摘　　要：近年来,彩虹全息图案被广泛应用于商品包装、货币和证件的防伪。这一制作技术也逐渐被造假者掌握,用于假印刷品彩虹全息图案的仿制。在案件实践中,需要对印刷品上的彩虹全息图案进行比对,以鉴定样品真伪、追溯制假源头。本文结合实际案例,探讨文检仪和激光全息鉴别仪在相关检验中的应用,对真伪商品及货币上印刷的彩虹全息图案进行了分析,建立了印刷品彩虹全息图案信息采集与比对方法,并对检验中的相关技术问题进行了探讨。该方法可有效区分彩虹全息图案真伪,并可进一步实现伪品的串并溯源。Rainbow hologram is at present widely used in commodity packaging,anti-counterfeiting with both the currency and certificate.However,some counterfeiters are also able to fabricate holographic patterns into their purposed prints of fake goods.Thus,a correlative forensic comparison is required to identify the authenticity of the involving samples and track their sources when the related rainbow holograms are suspicious of genuineness or becoming the crucial evidential item.Integrated into real cases,this paper compared the power of document examination workstation(VSC6000)and laser holographic identification instrument(Regula 2303)to discriminate the rainbow holographic patterns printed on genuine and counterfeit commodities and/or currencies.Consequently,a universal method was established about forensic comparison into image acquisition from rainbow hologram,demonstrating effective for forensic identification with the tested results.Additionally,discussions were made about the relevant technological problems,with the feasibility and applicability being illustrated of concatenating cases and tracking the sources of counterfeits.
