Description

基于微印刷的彩色动态立体莫尔图像薄膜及其制备方法 Three-dimensional micro-color moving image printed moiré based film and preparation

技术领域 FIELD

[0001] 本发明涉及公众光学视觉安全防伪技术领域,特别是涉及一种基于微印刷的彩色动态立体莫尔图像薄膜及其制备方法。 [0001] The present invention relates to optical vision technical field of public safety security, particularly to a moiré image on the color film and preparation method of micro-dynamic perspective printing.

背景技术 Background technique

[0002] 现有技术中主要使用的光学防伪技术分为三类:公众防伪、专业防伪和三线防伪。 [0002] The prior art optical security technique used mainly divided into three categories: public security, anti-counterfeiting and triplet professional security. 公众防伪主要采用形成主景图案、多通道和动态技术。 Public security mainly forming the main scene pattern and dynamic multi-channel technology. 专业防伪大都采用微缩图像和文字, 用自带光源的高倍放大镜可清楚辨别。 Most professional security using the thumbnail images and text, with their own light source can be clearly distinguished loupe. 三线防伪主要为衍射单元和各种编码技术等。 Three main diffraction lines security units and other various encoding techniques. 其中, 公众防伪技术特点是在通常状态下,不借助任何仪器,用肉眼或者感觉器官能够直接识别特征,最易为广大人民群众辨别,因此尤为重要。 Among them, the public security technology is characterized in a normal state, without the aid of any instrument, or with the naked eye can directly identify the characteristics of sensory organs, most likely for the masses to identify, and therefore particularly important. 它应具有两个基本要素:易于识别和难于伪造。 It should have two basic elements: readily identifiable and difficult to counterfeit.

[0003] 在公众防伪技术中,目前用于标签、钞票、信用卡等的光学防伪技术主要指衍射光变图像DOVID(Diffractive Optically Variable Image Devices),它包含人们所熟知的全息图像,包括后期发展起来的像素全息图、点阵全息图和动态莫尔图等。 [0003] In the public anti-counterfeiting technology, the current technology for optical security labels, banknotes, credit cards and other diffractive optically variable image mainly refers DOVID (Diffractive Optically Variable Image Devices), which comprises holographic images are well known, including the developed in the late pixel hologram, dot matrix holograms and other dynamic moire FIG. 知名的产品如法国Hologram Industries公司近年来发展的一种D0VID技术,其特点是图像分辨率为600LPI,但细微文字和线条的衍射单元分辨率可达到6000LPI,图像亮度高、色彩鲜艳。 Well-known products such as French Hologram Industries company recently developed a D0VID technology, which is characterized by an image resolution of 600LPI, but fine resolution diffraction unit text and lines can reach 6000LPI, high image brightness, color. 衍射识别技术的光栅结构是由瑞士Paul Scherrer学院Zurich实验室发明,它的光栅周期小于0.4μπι(模压全息光栅周期一般为Ιμπι)。 Diffraction grating structure recognition to a laboratory by the invention Zurich, Switzerland Paul Scherrer Institute, whose grating period is less than 0.4μπι (embossed hologram grating period is generally Ιμπι). 当水平位置观察图像(或文字)时为红色;将图像在平面内转90°时,则观察到深绿色。 When the horizontal position of the observation image (or text) is red; when the image in the plane of rotation 90 °, the dark green was observed. 机读的可靠性高且设备价格低。 Machine Readable high reliability and low equipment prices. 但是随着全息在票证、商标、包装等领域的广泛应用,许多厂家都具有了生产全息产品的能力,使得激光全息陷入了ig任危机。 But with the widespread application of holography in the ticket, trademarks, packaging and other fields, many manufacturers have the ability to produce holographic products, making the laser into a holographic ig any crisis.

[0004] 因此,人们迫切地需要寻找满足技术高、成本低、易识别、可仲裁的新一代大众技术。 [0004] Therefore, it is urgently seeking to meet the needs of high technology, low cost, easy to identify, the arbitrability of a new generation of Volkswagen technology. 如第四代激光组合全息图技术,将几十甚至几百个不同的二维图像通过几十甚至几百次曝光所记录的全息图,将三维目标的各个侧面及随时间的变化过程记录下来,即该全息图不仅能够记录和再现物体的三维空间(X,Y,Z)特性,还能记录和再现该三维物体随时间(Τ)的变化。 The fourth generation of laser technology composition hologram, a hologram dozens or even hundreds of different two-dimensional image recording by tens to hundreds of impressions, each side of the three-dimensional object, and changes over time in the recorded , i.e., the hologram is not only capable of recording and reproducing three-dimensional objects (X, Y, Z) characteristics, but also the recording and reproducing change over time of the three-dimensional object (Τ) a. 制作这种全息图对拍摄对象没有限制,需要对几十甚至几百帧二维图像进行记录,从而曝光次数是普通全息的几十甚至几百倍,这需要专用的仪器设备及更加精巧的工艺过程才能实现。 The production of such holograms no restrictions on the subject, the need for tens or even hundreds of frames of two-dimensional images are recorded, so impressions are ordinary holographic dozens or even hundreds of times, which requires special equipment and more sophisticated technology the process can be achieved. 还有如澳大利亚SecurencyPTY公司的G-switch技术,通过制作特殊的光学层,实现从一个方向观察是某颜色,从与之正交方向上观察是该颜色的补色,无须特殊培训和仪器。 There are companies such as Australia SecurencyPTY G-switch technology, by making special optical layers, viewed from one direction to achieve a certain color, viewed from a direction orthogonal thereto is the complementary color, without special training and equipment. 仅仅在一秒至几秒内,用简便的方法就可以鉴别。 In just a second to a few seconds by a simple method can be identified. 另外,人们还发明了安全线及其开窗技术,进一步提高技术门槛,安全线是起作用的薄膜材料制成的线状标志。 Further, it is also invented a security thread and windowing, further raising the bar, the security thread is made of a linear function flag film material.

[0005] 还有一类引人注目的新一代技术是将微透镜阵列(Microlens array,MLA)与微图形阵列(Micropattern array,MPA)结合实现的莫尔放大技术。 [0005] Another type of technique is the generation of striking a micro lens array (Microlens array, MLA) micro graphics array (Micropattern array, MPA) combined moiré achieve amplification. 莫尔放大涉及一种现象,从具有大致相同周期维度的微透镜阵列观察由相同微图形组成的阵列时可以产生这种现象, 即以微图形的放大或者旋转形式出现。 Moire magnification relates to a phenomenon, the phenomenon can be produced by the same micro-array as viewed from a pattern consisting of a microlens array having a period substantially the same dimensions, i.e., appears in amplified form of a microchip or a rotary pattern. 莫尔放大现象基本原理在MCHutley,R.Hunt, RFStevens and P.Savander,Pure Appl.0pt.3(1994),ρρ·133~142中有所描述。 The basic principle in an enlarged moire phenomenon MCHutley, R.Hunt, RFStevens and P.Savander, Pure Appl.0pt.3 (1994), ρρ · 133 ~ 142 are described. Drinkwater等在美国专利No.5,712,731中率先提出了将半球形微凸透镜阵列与微图形阵列结合的安全器件。 Drinkwater et pioneered in U.S. Patent No.5,712,731 proposes a security device semispherical micro-lens array with micro-patterned array of binding. 微图形在微凸透镜的后焦面附近,人眼在微透镜凸面侧观察可看到微图形的莫尔放大像,其中微凸透镜口径在50~250微米,微图形阵列通过凹版印刷的方式得到,最小分辨率为5微米。 Micro pattern in the vicinity of the back focal plane of the lenticules, the human eye can see the convex surface side microlens pattern moiré magnification micro image, wherein the micro-lens diameter of 50 to 250 microns, micro-array pattern obtained by gravure printing manner, The minimum resolution of 5 microns. 为了克服上述专利不利于制作超薄型(厚度小于50微米)器件的弊端,美国专利No · 2005/0180020A1 及后续专利No · 2008/0037131A1 中,RA Steenblik 等进一步扩展了依据上述微光学原理制作的安全器件范围,如微凸透镜口径减小至20~30微米, 焦距小于50微米,间隔层厚度小于50微米,微图形层具有多变的复杂排布,可以是透明、半透明、荧光、磷光、染、光变颜料等,并提出了若干基于反射工作模式的结构等等。 To overcome the above-mentioned patent is not conducive to production of ultra-thin (thickness less than 50 micrometers) devices drawbacks, U.S. Patent No · 2005 / 0180020A1 and subsequent Patent No · 2008 / 0037131A1, RA Steenblik other to further expand the production of micro-optics based on the above principle range safety devices, such as micro-lens to reduce the diameter of 20 to 30 microns, a focal length of less than 50 microns, the spacer layer thickness of less than 50 microns, micro-pattern layer having a variable complex arrangement, may be transparent, translucent, fluorescence, phosphorescence, dye, optically variable pigment, and made a number of operating modes based on the reflection structure or the like. 在中国专利安全元件(申请号200680048634.8)中提出了一种预定弯曲的布拉维点阵结构。 Proposed a predetermined curved Bravais lattice structure security element in Chinese patent (Application No. 200680048634.8) was. 通过设计微透镜阵列与微图形阵列及其排列组合,能够实现多种视觉效果:1)微图形放大:即原本看不见的微图形被放大至可由肉眼直接观察;2)正交移动:即沿某方向晃动时,观察到的宏观图像沿与之垂直的方向移动;3)立体感:观察到的宏观图像具有浮出或者沉陷于纸面的立体效果;4)运动变形:观察到的宏观图像在移动过程中还可能发生大小、形状等的变化。 By designing microlens array pattern array and arranged in combination with a variety of visual effects can be achieved: 1) amplifying a micro pattern: the original invisible micro pattern is enlarged to direct observation by the naked eye; 2) orthogonal to move: i.e., along when shaking a certain direction, a direction perpendicular thereto of the observed image along the moving macroscopic; 3) stereoscopic: macroscopic images observed with float or sink to the drawing of three-dimensional effect; 4) moving modification: the observed macroscopic images change in the size, shape, etc. may also occur during the move. 莫尔放大技术既可以单独实现对微图形的上述几种视觉效果,还可以同时实现上述几种视觉效果的组合,作为一种极易为肉眼辨视的一线技术,其不能为数字成像、扫描、复印、印刷设备等复制。 Moire amplification possible to achieve both of the above several separate micro-pattern visual effect, several combinations of the above may also be implemented while the visual effect, is easily visually identified as a line art of view, which is not digital imaging, scanning , copying, printing and copying equipment.

[0006] 美国专利和专利申请US5712731、US2005/0180020A1 以及US2008/0037131A1 中提出将微凸透镜阵列与微图形阵列结合应用于安全器件,其中的微图形阵列是通过凹版印刷的方式得到,最小分辨率为5微米。 [0006] U.S. patents and patent applications US5712731, US2005 / 0180020A1 and US2008 / 0037131A1 proposes a micro lens array and the array of micro pattern is applied in conjunction with security device, wherein the micro-array pattern is obtained by way of gravure printing, a minimum resolution of 5 microns. 主要制作方法是,在PET等柔性薄膜上涂布光刻胶,用带有微图文的凸版在光刻胶表面压印深度为数微米深的凹槽,通过刮涂方式将油墨填入凹槽,使得微图文显示相应的颜色。 The main production method, photoresist is applied, the micro relief with a number of graphic microns deep groove depth of the embossing on the surface of the photoresist flexible film such as PET, by way of the ink filled in the recess knife , so that the respective micro color graphic display. 在这种微图文制作方法中,图像的色彩是通过在凹槽中填充颜色油墨获得的,微图文颜色单一,不能形成彩色化显示;微图文特征尺寸为数微米,一般印刷油墨颗粒为几十个微米,因此,需特殊制作的纳米级油墨才能作为填充颜色油墨;为了使得足够多的油墨被填入凹槽,提高微图文与背景之间的对比度,凹槽深度将大于3微米。 In such micro by the production method, the color image is obtained by filling the ink colors obtained in the groove, a single micro-color graphics, the color of the display can not be formed; micro-graphic feature size of several microns, typically a printing ink particles tens of micrometers, therefore, require special ink in order to produce a nano-filled ink color; in order that sufficient ink is filled in the recess, to improve the contrast between the background and micro-graphics, the groove depth is greater than 3 m . 需要制作大深宽比金属压印模板,在大幅面动态图像制作时,提高了其工艺难度。 We need to make a large aspect ratio metal imprint template, when large-format motion picture production, improve its process more difficult.

[0007] 因此,针对上述技术问题,有必要提供一种基于微印刷的彩色动态立体莫尔图像薄膜及其制备方法。 [0007] Accordingly, for the above-mentioned technical problems, it is necessary to provide a color three-dimensional micro-dynamic moiré image printed film and preparation method.

[0050]微透镜微图形组合的莫尔图像薄膜同时保留了水平视差和垂直视差,保证观察角大,使得观察者在任何光环境下,不需要特殊的观察技巧就可以观察到三维彩色图形。 [0050] moire pattern image microlens film composition while retaining horizontal parallax and vertical parallax, to ensure a large viewing angle, so that an observer in any light environment, does not require special observation skills can be observed three-dimensional color graphics. 要显示清晰的三维图像,微透镜与微图形必须要严格匹配和密合,在其他实施方式中微图形的颜色不限于两套。 To show a clear three-dimensional image, the micro-lens and micro pattern must exactly match and adhesion, in other embodiments, the micro-pattern is not limited to two colors.

[0051 ]本实施方式中微图形的结构与微透镜的结构相匹配。 [0051] The micro structure of the present embodiment, the microlens structure pattern match. 微透镜列阵层的排列方式有两种,即正方形排列方式、或六角形排列方式。 There are two arrangements microlens array layer, i.e., a square arrangement, or hexagonal arrangement. 微图形的阵列排布与相应的微透镜阵列排布相对应。 The arrayed micro-pattern corresponding to the arrangement of the microlens array corresponds.

[0054]其中,微透镜阵列与微图形阵列的周期比为r,相互之间的夹角为Θ。 [0054] The period in which the microlens array micro array pattern ratio is r, the angle between each of Θ.

[0055] 微图形阵列层中微图形的整体尺寸为ΙΟμπι~100μLΉ,线宽为ΙμLΉ~20μηι。 [0055] The micro-array pattern in the overall size of the micro-patterned layer is ΙΟμπι ~ 100μLΉ, a line width of ΙμLΉ ~ 20μηι. 根据上述公式,微图形阵列经过微透镜阵列放大,图形放大率Μ为20~~。 According to the above equation, the micro-patterned array of the microlens array through the enlarged, 20 ~ Μ pattern magnification. 当r= 1时,图形放大率的计算公式为 When r = 1, the magnification is calculated pattern

Figure CN104191860BD00082

[0057]当θ = 〇.1°时,根据上述公式图形放大率Μ为573倍。 [0057] When θ = 〇.1 °, the above equation Μ pattern magnification is 573 times. 优选地,微图形高度为5μπι~ 100μπι,如果微图形高20um,贝lj莫尔放大后的图形大小为11.45mm,人们裸眼即可识别。 Preferably, the height of the micro-patterned 5μπι ~ 100μπι, if the micro pattern of high 20um, the size of the moire pattern beta lj the amplified 11.45mm, the naked eye can recognize it.
