Description

一种在印刷表面制作全息图文的方法 技术领域  Method for making holographic text on printing surface TECHNICAL FIELD
本发明涉及到一种激光全息图文成像技术及制作工艺，特别是在 印刷表面上直接制作全息图文的方法和工艺。  The present invention relates to a laser hologram image and text imaging technology and manufacturing process, and particularly to a method and process for directly making a hologram text on a printing surface.
背景技术 Background technique
全息图作为一项有效而实用的防伪技术受到人们的青睐，得到了 空前规模的迅猛发展。激光全息术迄今为止仍是国际上用于公众防伪 的主流技术，其便于识别，难于仿制和易于批量生产的特点很难在短 时期内被其它防伪技术所替代。全息和防伪几乎被人们等而视之， 似 乎全息商标就是防伪商标， 或防伪商标就是全息商标。  As an effective and practical anti-counterfeiting technology, holograms have been favored by people, and have achieved unprecedented rapid development. Laser holography is still the mainstream international anti-counterfeiting technology. It is easy to identify, difficult to imitate and easy to mass produce. It is difficult to be replaced by other anti-counterfeiting technologies in a short period of time. Holography and anti-counterfeiting are almost regarded by people as if holographic trademarks are anti-counterfeiting trademarks, or anti-counterfeiting trademarks are holographic trademarks.
激光像素全息照排制版系统的问世，标志着全息版的制作已从模 拟时代进入数字化时代，从而使得全息制版周期从过去的上十天， 缩 短到一两天， 制作成本大大降低； 同时也使得三维真彩色全息图更易 于实现， 并进入实用。  The advent of the laser pixel holographic phototypesetting system marks that the production of holographic plates has entered the digital era from the analog era, which has reduced the holographic platemaking cycle from the past ten days to one or two days, and greatly reduced the production cost. True color holograms are easier to implement and come into practical use.
当前全息复制技术仍以模压工艺（包括硬压及软压）为主， 将全 息图应用到商品上主要有以下几种方式：  The current holographic replication technology is still dominated by the molding process (including hard compression and soft compression). There are mainly several ways to apply the hologram to the product:
A、 标贴 最为原始的是人工标贴， 费时费力， 技术含量最低， 基 本上属于淘汰之列。 后来的自动标贴较前者效率大大提高， 需专 门的设备， 它对模压版的接缝质量要求较高。 目前部分企业使用 的就是这种方式。 这种方式适用于一般商标。  A. Labels The most primitive ones are manual labels, which are time-consuming and labor-intensive, and have the lowest technical content. They are basically eliminated. Later automatic labeling has greatly improved the efficiency compared with the former, requiring special equipment, which has higher requirements on the quality of the seams of the embossed plate. This method is currently used by some enterprises. This applies to general trademarks.
B、 复合 (如 ZL99109562)这种方式的工序较多， 需要专门的设备 和材料， 制作成本相对较高， 应用范围较窄， 主要适用于某些封 条。 B. Compound (such as ZL99109562) has many procedures and requires special equipment. And materials, the production cost is relatively high, the application range is narrow, and it is mainly applicable to some seals.
C、 烫印 （如 ZL00115394 ) 这是目前较为成功的一种应用方式。 它的速度较快， 可达到 10000张 /小时， 定位相对比较准确， 使用 这种方式的企业也因此获利较多， 但烫印设备特别是进口设 格昂贵， 使用的材料须由专门的厂家生产， 无形中阻碍了自身的 发展。  C. Hot stamping (such as ZL00115394) This is a relatively successful application method. Its speed is fast, it can reach 10,000 sheets / hour, and the positioning is relatively accurate. Enterprises using this method also benefit more, but the hot stamping equipment, especially imported fixtures, is expensive, and the materials used must be from specialized manufacturers. Production virtually impedes its own development.
总之， 现有全息应用技术的共同特点是：  In short, the common features of existing holographic application technologies are:
A、 多以塑料膜作为全息成像基材；  A. Mostly use plastic film as the holographic imaging substrate;
B、 需蒸镀金属层；  B. Metal layer needs to be evaporated;
C、 全息成像与产品制造（印刷、 成型）分别为两个独立的过程， 除烫印外， 一般是先进行全息图文复制，再在全息图上进行印刷； C. Holographic imaging and product manufacturing (printing, molding) are two independent processes. Except for hot stamping, holographic images are generally copied first, and then printed on the hologram.
D、 为了在纸塑铝复合制品上获得透明全息效果， 需在金属层上 采用透明油墨印刷（相当于金属印刷），不但改变了原有印刷工艺， 也大大提高了生产成本。 D. In order to obtain transparent holographic effect on paper-plastic aluminum composite products, it is necessary to use transparent ink printing (equivalent to metal printing) on the metal layer, which not only changes the original printing process, but also greatly increases the production cost.
美国专利（US5155604 )虽公开了一种在纸或塑料基材上直接涂 布一层热敏性材料作为全息图像复制层， 并经过加热、模压形成全息 图案的方法。但是该种方法仅限于制作全息像纸或全息胶片， 作为一 种全息装饰图案， 并非用做防伪技术， 而且是在非印刷表面上制作， 如何将激光全息图文直接制作在某种基材印刷有图案的层面上， 尚属一难题。其关键在于基材的印刷层面的图案是已经印制好的， 在 印刷层面上制作激光全息图文层必须既不破坏已印好的印刷图案又 须对印刷层具有优良的附着力。如果能将激光全息图文视作一种非油 墨的印刷图文， 即利用光的^ "射效应来再现设计图案和色彩， 那么传 统的全息技术将会得到新的发展。 The United States patent (US5155604) discloses a method of directly coating a heat-sensitive material as a holographic image replication layer on a paper or plastic substrate, and then heating and molding to form a holographic pattern. However, this method is limited to making holographic paper or holographic film. As a holographic decorative pattern, it is not used as anti-counterfeiting technology, but also on non-printed surfaces. How to make laser holograms directly on certain substrates and print At the level of patterns, it is still a problem. The key is that the pattern on the printing layer of the substrate is already printed. The laser hologram text layer on the printing level must neither destroy the printed printing pattern nor have excellent adhesion to the printing layer. If the laser hologram can be regarded as a kind of non-ink printed graphics, that is, the design effect and color are reproduced by using the radiation effect of light, then the traditional holographic technology will have new development.
发明概述 Summary of invention
本发明的目的在于针对现有全息防伪技术的不足，提出一种在基 材已有印刷油墨的表层上， 经过特殊的方法和工艺处理， 进行全息图 文复制的激光全息图文成像方法。  The purpose of the present invention is to address the shortcomings of the existing holographic anti-counterfeiting technology, and propose a laser holographic image and text imaging method for performing holographic text copying on a surface layer of a printing ink on a substrate through a special method and process.
本发明的另一目的是提出一种根据上述激光图文成像方法所确 定的具体制作工艺。  Another object of the present invention is to propose a specific manufacturing process determined according to the above laser image and text imaging method.
本发明的目的是通过下述技术方案得以实现的： 选择一种基材， 基材可以是纸、 塑料、 金属或皮革等某一种基材， 基材可以是片材或 卷材。 先按常规印刷工艺进行油墨印刷， 在基材上形成一印刷图层， 再在已印刷好图案的基材印刷层表面上 ,涂布一层具有激光全息图文 承印功能的透明全息涂层介质，全息涂层介质的涂布方法可以采用辊 涂、 喷涂、刷涂或淋涂等任一种涂布方式， 在印刷层上涂布一层具有 热塑性的透明全息涂料， 并通过红外线辐射加热干燥结膜， 形成全息 介质层， 若基材表面较为粗糙（如普通的白纸板等）， 可对该全息涂 层介质进行压光处理， 以便得到一层光亮平整的涂层， 以此作为全息 图文的记忆层，再利用模压机进行全息模压复制（卷材可利用通用模 压机， 片材应使用特制的平台式模压机）， 将涂布有全息涂层介盾的 基材， 通过一模压机， 模压机上的模压模具外表面装有全息模板， 在 带有全息涂层介质的基材送入模压机时，全息涂层在受热软化的同时 又在全息模板的作用下进行热模压复制全息图文，最后在印刷层表面 之上形成一层透明的全息图文层，该全息图文层可利用光的衍射效应 来再现设计图案和色彩。 其模压方式可以为热滚压方式，模压机上的 模压模具为中心为中空的辊筒，辊筒中心的中空部分充满用于软化全 息涂层的热油， 在带有全息涂层介质的基材送入模压机时， 全息涂层 介盾在辊筒内的热油作用下迅速软化，并在全息模板的作用下滚压下 复制全息图文。 The object of the present invention is achieved by the following technical solutions: selecting a substrate, the substrate may be a certain substrate such as paper, plastic, metal, or leather, and the substrate may be a sheet or a roll. First, ink printing is performed according to a conventional printing process, a printing layer is formed on the substrate, and then a transparent holographic coating medium with a laser holographic text printing function is coated on the surface of the printed layer of the printed substrate. The coating method of the holographic coating medium may adopt any coating method such as roller coating, spray coating, brush coating, or shower coating, etc., and a layer of a transparent transparent holographic coating with thermoplastic is coated on the printing layer, and dried by infrared radiation heating and drying Conjunctiva to form a holographic medium layer. If the surface of the substrate is rough (such as ordinary white paperboard, etc.), the holographic coating medium can be calendered to obtain a bright and flat coating, which is used as the hologram. Memory layer, and then use a compression molding machine for holographic molding replication (coil can be used for general compression molding, sheet material should use a special platform type compression molding machine), the substrate coated with the holographic coating shield is passed through a compression molding machine The outer surface of the compression mold on the compression press is equipped with a holographic template. When the substrate with the holographic coating medium is fed into the molding machine, the holographic coating is softened by heat while being hot-molded to replicate the holographic text under the action of the holographic template, and finally a transparent layer is formed on the surface of the printed layer Holographic text layer, which can use the diffraction effect of light to reproduce design patterns and colors. The molding method can be a hot rolling method. The molding die on the molding machine is a hollow roller. The hollow part of the roller center is filled with hot oil for softening the holographic coating. On the substrate with the holographic coating medium, When fed into the molding machine, the holographic coating shield softens quickly under the action of the hot oil in the roller, and is rolled under the action of the holographic template to replicate the holographic text.
在基材印刷图案层面上进行激光全息图文的成像机理与其它传 统的基材（塑料薄膜、 镀铝膜）基^目似， 均为通过全息照相得到全 息照片， 再将全息照片翻制成全息金属版， 然后通过热模压工艺将全 息图文复制到印刷品上。但具有油墨的印刷层面的表面性质与塑料薄 膜或镀铝膜有着明显的差别。可用于制作全息制品的薄膜本身具有热 塑变形性质， 且表面平整， 能直接进行全息图文压印， 尤其是经镀铝 后， 由于金属铝层的反射效应， 大大增强了全息图文的可视效果。 而 印刷品则不然， 既不能直接对油墨进行全息图文压印， 更不能对印刷 品进行镀铝处理（铝层覆盖油墨， 将丧失原有印刷效果）。 因此， 要 在印刷层面上制作具有全息效果图案， 需要借助一种特殊的承印介 质。 这种介质应具有优良的热塑变形性能， 且变形后能得到稳定的精 细全息光栅条纹， 同时这种介质必须具有足够的透明性， 以保证原有 印刷图文和色彩的可视性，我们把这种特殊的全息图文承印介质叫做 全息涂层。 根据基材及激光全息图文成像的一些特性，本发明所采用的全息 涂层为透明的热塑性材料， 为溶剂型的共聚单体物， 其中包含有溶剂 型共聚树脂，溶剂型的共聚单体物经过合成形成一种共聚合成树脂涂 料作为激光全息图文成像复制涂料，该溶剂型涂料又分为醇溶性共聚 合成树脂涂料或水溶性共聚合成树脂乳液涂料。 其涂料成分都由主 剂、 助剂和溶剂等三个部分组成， 主剂（成膜树脂）是涂料的成膜物 质， 膜层的品质及理化性能， 如光泽度、 耐折性、 后加工适性等均与 主剂的选择有关。其中， 水溶性涂料的主剂可用水性树脂和聚乙烯醇 制成的共聚树脂。溶剂可以是包含有水、乙二醇乙醚和丁醇等的液体。 合成后所得到的是一种具有高折光率、 高光泽、 耐磨、 柔韧性、 抗水 性等综合性能优异的环保型全息涂料。醇溶性涂料的主剂可以是单体 共聚合成树脂和聚氨酯树脂，溶剂可以是包含有乙二醇乙醚和丁醇的 液体， 该涂料具有成膜性好、 光泽度高、 透明度高、 耐磨、 耐水、 耐 老化等一系列优良性能， 而且适用性极强。 The imaging mechanism of laser holograms on the substrate printed pattern level is similar to that of other traditional substrates (plastic film, aluminized film). Both obtain holograms through holography, and then turn the holograms into The holographic metal plate is then copied to the printed matter by a hot stamping process. However, the surface properties of the printed layer with ink are significantly different from plastic films or aluminized films. The film that can be used to make holographic products has thermoplastic deformation properties and has a flat surface, which enables direct holographic text imprinting, especially after aluminum plating, due to the reflection effect of the metal aluminum layer, the holographic text can be greatly enhanced. Depending on the effect. However, the printed matter is not the same. It is not possible to directly emboss the ink on the ink, nor to aluminize the printed matter (the aluminum layer covers the ink, and the original printing effect will be lost). Therefore, to produce a pattern with a holographic effect on the printing level, a special printing medium is needed. This medium should have excellent thermoplastic deformation properties, and stable fine holographic grating stripes can be obtained after deformation. At the same time, this medium must have sufficient transparency to ensure the visibility of the original printed graphics and colors. We This kind of special holographic printing media is called holographic coating. According to some characteristics of the substrate and laser holographic imaging, the holographic coating used in the present invention is a transparent thermoplastic material and is a solvent-based comonomer, which includes a solvent-based copolymer resin and a solvent-based comonomer. After the materials are synthesized, a copolymerized resin coating is formed as a laser holographic image reproduction coating. The solvent-based coating is further divided into an alcohol-soluble copolymerized resin coating or a water-soluble copolymerized resin emulsion coating. The coating ingredients are mainly composed of three parts: the main agent, the auxiliary agent and the solvent. The main agent (film-forming resin) is the film-forming substance of the coating. The quality and physical and chemical properties of the film layer, such as gloss, folding resistance, and post-processing The suitability is related to the choice of the main agent. Among them, the main agent of the water-soluble paint can be a copolymer resin made of an aqueous resin and polyvinyl alcohol. The solvent may be a liquid containing water, ethylene glycol ether, butanol, and the like. After synthesis, an environment-friendly holographic coating with high comprehensive properties such as high refractive index, high gloss, abrasion resistance, flexibility, and water resistance is obtained. The main agent of alcohol-soluble coatings can be the copolymerization of monomers into resins and polyurethane resins. The solvent can be a liquid containing ethylene glycol ether and butanol. The coating has good film-forming properties, high gloss, high transparency, abrasion resistance, A series of excellent properties such as water resistance and aging resistance, and the applicability is extremely strong.
为了在全息涂层上获得良好的全息图视觉效果，光洁平整的涂层 表面质量是关键因素，这就要求全息涂料光泽度高、流平性好。此外， 涂料的其它理化性能， 如耐折性、 耐磨性、 后加工适性等也是十分重 要的。  In order to obtain a good holographic visual effect on the holographic coating, the smooth and smooth coating surface quality is the key factor, which requires high gloss and leveling of the holographic coating. In addition, other physical and chemical properties of the coating, such as folding resistance, abrasion resistance, and post-processing suitability, are also very important.
从光学原理来看，记录在全息涂层上的全息图文是利用光的衍射 效应来再现全息效果，而原有油墨印刷图文是利用光的反射效应来表 现印刷效果， 由于对光的利用方式不同， 全息图文并不干扰原有油墨 印刷的效果，相反， 透明的全息涂层使两种印刷效果能够同时得到表 现， 并形成一种特殊的装饰效果。 From the perspective of optical principles, the holographic images and text recorded on the holographic coating use the diffraction effect of light to reproduce the holographic effect, while the original ink printed images and text use the reflection effect of light to express the printing effect. Due to the use of light In different ways, the holographic text does not interfere with the original ink printing effect. On the contrary, the transparent holographic coating enables the two printing effects to be displayed at the same time. And form a special decorative effect.
采用本发明技术主要具有如下技术特征：  Adopting the technology of the present invention mainly has the following technical characteristics:
