Embodiment
Fig. 1 is the false proof making process flow diagram with photoetching two-dimension code label of the present invention, first be that the corresponding information of Quick Response Code providing according to client generates original Quick Response Code, then utilize the software that image processing software Photoshop and lithographic equipment carry that original two dimensional code is processed into the picture format that lithographic equipment can be identified.Obviously single Quick Response Code photoetching document form is too simple, and false proof performance is not greatly improved yet, thereby next we can embed other special light lithography to strengthen whole anti-counterfeiting performance under not affecting the prerequisite of Quick Response Code scanning recognition, be about to layout and according to label position design, need to be integrated into label image by multiple photoetching technique, after the image that has completed the Quick Response Code after integrated is processed, just can utilize lithographic equipment on photoresist sheet, to prepare the mother matrix of two-dimension code label, finally utilize ripe holographic label production technology, it is electroforming, mold pressing, cross cutting just can be realized the batch production of photoetching two-dimension code label.
Below in conjunction with an actual photoetching Quick Response Code, make above-mentioned technological process is described further.Figure 2 shows that the original two dimensional code that represents Light Electrical, Shanghai Research of Integration institute network address, this Quick Response Code is that the black graphics by white background forms, and the distribution of black graphics determines the content of Quick Response Code.The Quick Response Code of this form forms very simple, general Quick Response Code generates software just can obtain same Quick Response Code easily, and by copying later Quick Response Code and initial Quick Response Code are there is no what difference, thereby the threshold of copying is very low, such Quick Response Code is almost not possess any false proof function.
Next original Quick Response Code need to utilize image processing software Photoshop to carry out an anti-phase processing, be about to the color swap of its black and white part, as shown in Figure 3, the Quick Response Code after anti-phase processing can not directly carry out scanning recognition with intelligent terminal.Next, anti-phase Quick Response Code figure will carry out gray scale with this and rasterizing is processed, and this is because black is not to be identified in lithographic equipment.In addition, rasterizing is processed and to be referred to a processes pixel of script image is become to other pel array of different grey-scale, and in a preferred embodiment, a pixel is processed into 2 * 2 other pixels of different grey-scale, and the pattern in 2 D code after processing as shown in Figure 4.It is can identify file layout in order to make original pattern in 2 D code can be converted into lithographic equipment that this gray scale and rasterizing are processed, and increases the out readability of image of photoetching.
In order to promote security feature and the aesthetic property of photoetching Quick Response Code, next more integrated other lithographic results under the prerequisite that does not affect Quick Response Code scanning recognition, in a preferred embodiment, introduced other five kinds of lithographic results, the photoetching Quick Response Code design sketch after integrated as shown in Figure 5.Wherein, 51 is the Quick Response Code after image is processed shown in Fig. 4, and it is that the length of side is the square pattern of 1.6 centimetres; 52 is 2D photoetching word, and some essential informations that comprise company are located at the below of pattern in 2 D code 51; 53 is dynamic group flower lithographic results, is that the staggered group forming of meticulous lines by different colours spends effect, is located at the surrounding of pattern in 2 D code 51, and frame Outside Dimensions is 2 centimetres, inside encloses and is of a size of 1.8 centimetres; 54 is miniature word lithographic results, and it is the miniature word being embedded in pentagram, and wherein pentagram is of a size of 0.1 centimetre, 150 microns of left and right of word size, be located at the left and right sides of pattern in 2 D code 51, the miniature word on the left side is Wei Na, and the miniature word on the right is Nano; 55 is 3D ball lithographic results, diameter is 0.6 centimetre, is located at the center of pattern in 2 D code 51, and because pattern in 2 D code has certain error correction, in embodiment, the size Selection of 3D ball 55 is the scan functions that do not affect original pattern in 2 D code; 56 is random streaks lithographic results, and its particular location only has the people of mapping to know, naked eyes are unresolvable, thereby the difficulty of copying is very large, thereby can further promote the anti-counterfeiting performance of photoetching Quick Response Code.
It should be noted that, Fig. 5 is only some photoetching techniques for illustrating that implementation method of the present invention adopts, thereby can obtain according to the more diversified photoetching technique of needs stack the photoetching two-dimension code label of different-effect in the actual process of implementing, also can be according to client's the more integrated information of entering other that require, as pattern with house mark etc.Photoetching technique comprises general two-beam interference technology, 3D photoetching technique, true color photoetching technique, shrink technology, random streaks embedded technology.
Completed pattern in 2 D code design and integrated after, just can utilize lithographic equipment to prepare integrated two-dimension code label mother matrix.Mother matrix utilizes double light beam laser on photoresist sheet, carry out pointwise interference exposure and form, thereby every bit reality is all a small grating, the position angle of grating is corresponding to the color of the integrated two-dimensional code pattern of design, and whole photoetching two-dimension code label belongs to the pattern that grating array forms in fact.Figure 6 shows that the local enlarged diagram of photoetching Quick Response Code, wherein 61 for photoetching pixel schematic diagram, and its size is a kind of between 20 microns, 40 microns, 80 microns and 160 microns, according to actual photoetching, requires to select.62 is certain azimuthal grating schematic diagram, and the cycle is 2 microns of left and right, and azimuthal size depends on the color in its corresponding pattern.
After having completed the mastering of photoetching two-dimension code label, just can carry out mass production by electroforming, mold pressing, die-cutting process.The reading manner of this photoetching Quick Response Code and ordinary two dimensional code are as good as, and only need place it in the view-finder of intelligent terminal and can complete scanning to high-visible.
It is more than a kind of false proof method for making with photoetching two-dimension code label that the present invention proposes, this Quick Response Code that utilizes micro-nano structure array to form, the function of tracing to the source of existing ordinary two dimensional code, simultaneously again can integrated numerous Techniques of Optical Security, can not utilize the modes such as duplicating, scanning, printing to carry out reproduction to the photoetching two-dimension code label of preparing, possess powerful antiforge function, and visual effect to more be dazzled than ordinary two dimensional code color brilliant.
