Description

真彩色荧光制品的制作方法、真彩色荧光制品及真彩色荧光工艺品 技术领域
本申请属于真彩色荧光制品技术领域，尤其涉及一种真彩色荧光制品的制作方法、真彩色荧光制品及真彩色荧光工艺品。
背景技术
防伪无色荧光油墨通常也称隐色油墨，是在紫外光(200nm-400nm)等光源照射下发出可见光(400nm-800nm)的特种油墨。防伪无色荧光油墨的主要成分是荧光颜(染)料，它是功能性发光颜料，与一般颜料的区别在于当外来光(含紫外光)照射时，吸收一定形态的能，不转化成热能，而是激发光子，以可见光形式将吸收的能量释放出来，产生不同色相的荧光现象。防伪无色荧光油墨在紫外光的照射下形成各种色彩，而当光停止照射后，发光现象即消失。防伪无色荧光油墨中的荧光粒子会产生一定范围的光亮和特别干净的颜色，如黄、橙黄、红、晶红、绿和青等。产生这种效果的关键在于这种油墨中包含有特种彩色颜料，它能吸收紫外波段的能量，并将这些能量转换成较长的可见光的波长。防伪无色荧光油墨在防伪印刷中的应用非常广泛，具有实施简单、成本低、隐蔽性好、色彩鲜艳、检验方便、重现性强、变色多样和能适应大规模生产线或包装印刷需求等特点。通常用于钞票、邮票、金融凭证(如支票、债券、股票、商业票据、银行承兑票等)、名烟、名酒及一些高档商品的包装防伪印刷等。若与其他防伪技术结合使用，可产生更好的防伪效果。现有的印制彩色荧光制品的制作常印制防伪底纹及团花等线条，但色彩搭配单一，如各类防伪票券、防伪标识等；同时，用于印制图像或图案时，多为采用假彩色方式呈现颜色，对图案的表现能力有限。

随着人们对印刷包装的要求不断提高，荧光油墨的使用也越来越广泛。这主要是因为荧光油墨不仅能够呈现多样而神秘的色彩效果，而且还起到较大的防伪作用。无色荧光具有实施简单、隐蔽性好、色彩鲜艳、检验方便及重现性强等 特点，在防伪印刷中应用非常广泛，无色荧光油墨广泛应用于邮票、钞票、增值税发票、各种证件、烟酒包装等印刷中，也应用于产品的质量检测及娱乐场所的艺术展示，其不仅提高印刷品的防伪效果，增强其附加值，同时也提高印刷品的艺术观赏性。
如图1所示，本申请实施例提供一种真彩色荧光制品的制作方法，包括以下步骤：
S1：提供待印刷图像，将待印刷图像转换为加色模式以形成第一预制图像，加色模式即为RGB模式，在自然界肉眼所能看到的任何色彩都可以由红蓝绿三种色彩混合叠加而成，因此也称为加色模式，具体地，可通过电脑上的photoshop等软件将该待印刷图像进行模式转换；
S2：将第一预制图纸处理以形成彩色阴图形式的第二预制图像，具体地，是将第一预制图像的颜色色相反转，以形成该第二预制图像，第二预制图像具有R通道、G通道以及B通道，R通道内具有第二预制图像的红色的K1图像信息，G通道内具有第二预制图像的绿色的K2图像信息，B通道内具有第二预制图像的蓝色的K3图像信息，反相即将图像的颜色色相反转以形成彩色阴图形式的该第二预制图像；
S3：将R通道的图像信息制作形成第一印版，将G通道的图像信息制作形成第二印版，并将B通道的图像信息制作形成第三印版，并分别通过第一印版、第二印版以及第三印版转印至承印物上形成真彩色荧光制品。
本申请实施例的真彩色荧光制品的制作方法，通过先将待印刷图像转换为加色模式，使得该第一预制图像能够将该待印刷图像分离出红蓝绿三种基色，再将该第一预制图像反相形成第二预制图像，并将第二预制图像分离形成R通道、G通道以及B通道，R通道内具有第二预制图像的红色的K1图像信息，G通道内具有第二预制图像的绿色的K2图像信息，B通道内具有第二预制图像的蓝色的K3图像信息，并分别制作形成第一印版、第二印版以及第三印版，再分别通过第一印版、第二印版以及第三印版转印至承印物上便可形成真彩色荧光制品。由于无色荧光为激发发光，基于色光加色法呈现原理，通过红、绿、蓝三色光按照图像阶调和色彩混合来再现彩色的待印刷图像。且该真彩色荧光制品在紫外 光下呈现明亮鲜艳、阶调分明的彩色图像，增强了防伪特征的表现力和观赏性。通过该方法生成的防伪印刷品，基于不同普通彩色印刷的原理，即使用色光加色法原理，并结合彩色图像半色调工艺，使荧光图像呈现出具有连续调变化的彩色效果，防伪强度进一步提升，处理难度更大，更难以伪造，防伪力度进一步提高同时具有隐蔽性。通过该方法生成的荧光展示品，在荧光灯照射下呈现出连续调变化的颜色丰富变化的图像，该图像观赏性强，图像更逼真具象，表现能力进一步增强。
在一个实施例中，将K1图像信息制作形成第一印版，将K2图像信息制作形成第二印版，并将K3图像信息制作形成第三印版具体为：将K1图像信息进行半色调处理形成H1半色调图像，将K2图像信息进行半色调处理形成H2半色调图像，以及将K3图像信息进行半色调处理形成H3半色调图像。半色调技术是指用少量的色彩将一幅连续色调图像(如灰度图像和彩色图像)量化为一幅二值图像或是只有少数几种色彩的彩色图像，并且量化后图像在一定距离的视觉效果和原始图像相似的技术。通过半色调处理，使得能够将K1图像信息、K2图像信息以及K3图像信息分别制作成便于印刷或喷印设备所支持的二值图像，即H1半色调图像、H2半色调图像以及H3半色调图像。
在一个实施例中，半色调处理包括调幅加网和调频加网。数字调幅加网技术(点聚集态网点技术)在数字加网技术中，调幅加网是用不可见的、行列排列有序的网格分割图像，每个网格按照一定的角度、加网线数生成面积不同的网点。在生成记录网点的黑/白时，总要受到加网角度、网点形状和加网线数的限制，所以在每个位置上设置的自由度相对较低。调幅加网技术又称为点聚集态网点技术，这种加网技术得到的是聚集态的记录点。我们通常将聚集在一起的点称为传统网点，它由图像信息的灰度层次来控制网点的增长。调频加网技术(点离散态网点技术)调频加网从某种意义上来说又可以称为点离散态网点技术，该技术得到的是离散分布的记录点。这种加网计算不再受网格的限制，直接以发散无序的记录点阵象素群构成图像，在每个可记录位置上设置的自由度高于调幅加网，这使得调频加网图像具有较高的信息容量。调频加网又称随机加网，随机性在数学中用于描述分析和预言粒子在粘稠液体中运动的过程，印刷 中则用于描述精确摆放点子的方法，以产生随机性并产生色调级的感觉。实际上，网点位置是基于计算的随机性。网点的空间分布是通过算法来分配的，根据色调的统计估算值和图像邻近部分的细节来分布点子，不会出现明显的堆积或不需要的微型点累积。
在一个实施例中，通过第一印版、第二印版以及第三印版转印至承印物上形成真彩色荧光制品具体为：在第一印版上施放无色荧光红油墨，在第二印版上施放无色荧光绿油墨，在第三印版上施放无色荧光蓝油墨，并分别将第一印版、第二印版以及第三印版转印至承印物上。分别通过设置至少三个印版，且在第一印版上施放无色荧光红油墨，在第二印版上施放无色荧光绿油墨，在第三印版上施放无色荧光蓝油墨，使得能够通过该三个印版将各种颜色调配出来，进而还原待印刷图案的原本颜色。
在一个实施例中，第一印版、第二印版以及第三印版上还设有用于控制白平衡的色带和/或测控条。
在一个实施例中，承印物为无荧光纸，具体可为无荧光证券纸或无荧光防伪纸。由于现有的纸上均具有荧光，若使用本身具有荧光的纸作为承印物，会影响多色荧光制品的显示效果，而无荧光纸或不具有荧光，这样，便可作为承印物并使得无色荧光制品具有更显著的显色效果。
在一个实施例中，无色荧光红油墨为无色荧光正红油墨，无色荧光绿油墨为无色荧光正绿油墨，无色荧光蓝油墨为无色荧光正蓝油墨。为更好的再现还原彩色的待印刷图案的色彩和阶调，优选采用颜色纯正的无色荧光正红、无色荧光正绿、无色荧光正蓝、无色荧光正黄等颜色的油墨。
在一个实施例中，通过第一印版、第二印版以及第三印版转印至承印物上形成真彩色荧光制品具体为：分析并判断待印刷图案的主基色，该主基色是指红、蓝、绿中三种基色占比最大的颜色。将与该主基色对应的印版调整为最后一个色组印刷。可通过分析原稿主基色，适应性调整印刷色序；如红色为主基色的原稿，采用将红色作为最后一个色组印刷。
在一个实施例中，分析待印刷图案的色调，将一种中间无色荧光油墨的图像信息K4制作形成第四印版，并通过第四印版将对应的中间无色荧光油墨转印至承 印物上。例如，红光与绿光可形成黄光，为增强再现真彩色无色荧光图像黄色的表现，可将同时含有红色和绿色的全部或部分内容生成一个灰度图像K4，并经半色调处理，形成对应半色调图像H4，以及制作第四印版，并对第四印版对应施放无色荧光黄油墨，再依次通过第一印版、第二印版、第三印版以及第四印版将图像信息转印至承印物上。同理，红光与蓝光可形成品红色，绿光和蓝光可形成青色，可采用上述同样的方式制作印刷文件和印版，并分别对应施放无色荧光品红墨和无色荧光青色墨，实现无色荧光真彩色印刷的效果增强。
在一个实施例中，中间无色荧光油墨包括至少两种基色。例如，红光与绿光可形成黄光，红光与蓝光可形成品红色光，绿光和蓝光可形成青色光，红光、绿光和蓝光可形成白光，为增强再现真彩色无色荧光图像白色的表现，可将同时含有红色、绿色和蓝色的全部或部分内容生成一个灰度图像K4，并经半色调处理，形成对应半色调图像H4，以及制作第四印版，第四印版对应施放无色荧光白油墨，实现无色荧光白色印刷的效果增强。
本申请实施例还提供一种真彩色荧光制品，包括承印物和印刷于承印物上的图案，图案采用上真彩色荧光制品的制作方法印刷于承印物上。通过采用上述方法制作的真彩色荧光制品，借助无色荧光油墨，通过印刷的方式实现具有明亮荧光的连续调真彩色图像，该图像在自然光下呈现无色，常规的扫描、分色设备无法识别，仅可在特定光源下查看其防伪特征而无从复制再现，较大程度加大了防伪难度；同时，在紫外光下呈现明亮鲜艳、阶调分明的彩色图像，增强了防伪特征的表现力和观赏性。
在一个实施例中，图案通过多种无色荧光基色印刷制成。
在一个实施例中，承印物为无荧光纸，具体为无荧光证券纸或无荧光防伪纸。由于现有的纸上均具有荧光，若使用本身具有荧光的纸作为承印物，会影响多色荧光制品的显示效果，而无荧光证券纸或无荧光防伪纸均不具有荧光，这样，便可作为承印物并使得多色荧光制品具有更显著的显色效果。
本申请实施例还提供一种真彩色荧光工艺品，包括上述的真彩色荧光制品。
在一个实施例中，荧光工艺品还包括光源，光源指向真彩色荧光制品设置，且光源为能够照射波段为300nm～400nm的光的紫外光源。为更好的在365nm紫外光 环境下体现无色荧光的颜色，观察环境优选采用主波长为365nm、纯度高的紫外灯光源照射，为更好的在365nm紫外光环境下体现无色荧光的颜色，观察环境优先选择暗室，避免周围环境光的影响；在一个实施例中，通过紫外光源的启闭，使得真彩色荧光制品能够呈现出荧光特征效果。且真彩色荧光制品用于防伪票证、防伪标识或防伪包装等防伪产品领域时，便可有效增强无色油墨荧光涂料的应用方式和展示效果，相比现有的无色油墨荧光涂料的运用，具有更佳的防伪效果。当真彩色荧光制品用于博物馆或展览馆等室内外展示、装帧装饰和广告等领域时，在增加展示多元化的同时，也增强了展示的趣味性、新颖性以及用户参与度。
以上仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
