Description of the Invention: [Technical Field] The present invention provides a method for producing a color change effect of a color changing ink, and more particularly, a method suitable for producing a plurality of color changing effects in the field of printing anti-counterfeiting technology, The original color-changing characteristics of fine color-changing inks are used as the basis for identification, and the color-changing effect is extended by using printing technology to break through the current color-changing effect, which is limited to the limitation of monochrome to monochrome and a few colors, thereby generating various color-changing effects of visual color mixing. Technician. [Prior Art] Know: In the surrounding environment of our daily life, we often come into contact with some printed or packaged products with valuable value. These valuable printed materials are sometimes banknotes, checks, and sometimes stocks or other Related documents, etc.; and packaging products sometimes include books, documents, clothing or other daily necessities; these valuable printed and packaged products often have many images or images produced, which are different from the text. Different visual reductions can be explained, and images or images can be turned over by printing, printer printing, and drawing of raw materials. With the continuous improvement of technology standards and the gradual establishment of the market economy' The close combination of anti-counterfeiting technology and printing technology is of great significance for combating counterfeit and shoddy products and regulating market order. In addition, the application range of printing ink anti-counterfeiting technology is increasingly wide, and the benefits are getting better and better. Among them, the anti-counterfeiting ink with a wide range of applications is taken as an example, and it has been combined with many subject areas (such as 200823059. Guangfu, Hua ¥, Electromagnetics and spectroscopy, etc., W integrated ink anti-counterfeiting technology, and anti-counterfeiting ink is a special printing ink made by a special process by adding a special anti-counterfeiting material to the ink binder. Huai's current color-changing inks are all color-changing mechanisms of material properties, and due to the limitations of the materials themselves, most of them are a few color changes or fixed color-to-monochromatic color change modes (eg blue-magenta), color Monotonous, cost Ma An, 11-color formula is also mastered in the oil-hard hand, which will be affected by the business application and anti-counterfeiting effect of the back end, such as when applied in packaging and printing, it will often destroy the overall appearance. Design aesthetics, monotonous color changes: It may also be easy to crack. Therefore, the current anti-counterfeiting color-changing inks have the following drawbacks: - Since the color-changing ink itself is subjected to _, it is only capable of fixing a single color to a single color, and there is a bottleneck of a small color change. Second, due to the hiding of the color of the color machine, therefore, according to the preferences of the anti-counterfeiting designer, random color mixing with a variety of color discoloration, relatively weakening its anti-counterfeiting mechanism 'reduce its technical threshold, reduce its application range, and increase Counterfeiting risks. The lack of the above is the problem that the inventor of the present invention most wants to overcome, and the problem presented by it is also the motivation of the inventor of the present case to develop the case. Therefore, 'in this fast-changing market, only the products that constantly produce special and mineral effects are the way to win the business of Wei, so how to stand out in the fierce market of competition 200823059 to enhance the industry in this kind of products. The competitive strength is the purpose of the application for this case. SUMMARY OF THE INVENTION In view of the above-mentioned reference, the conventional anti-counterfeiting color-changing inks are: color, color effect cannot be extended, color flexibility is limited, color change effect and application range cannot be reduced according to design aesthetics, and the like. Defects and troubles; therefore, the inventor has been working on the manufacturing design of the industry for many years, and after a long period of hard work of research and experimentation, he finally developed and designed a method of "a variety of discoloration effects of color-changing inks". The main object of the present invention is to provide a method for producing a plurality of color-changing effects of a color-changing ink, by which the material properties of the ink of the (four) color ink can be broken, and the conventional monochrome-to-monochrome or a few colors can be overcome. The bottleneck of discoloration can be based on the preferences of the anti-counterfeiting designer. The color mixing can be mixed with the color of the hair color, the anti-counterfeiting color recognition mechanism is strengthened, the technical threshold is increased, the application range is increased, and the risk of counterfeiting is reduced. [Embodiment] In order to facilitate the review and understanding of the technical means and operation process of the present invention, an embodiment will be described in conjunction with the drawings, which will be described in detail below. The invention relates to a method for producing a color change effect of the color changing oil 4, which is based on the original color change of the color changing ink, and the color change 200823059 ink generally refers to temperature change, pressure change, sensitization or It is a color changing method of driving liquid, and can be used for color changing ink of anti-counterfeiting application. Please refer to the first figure, which is a schematic diagram of the method of the present invention. As is clear from the figure, the method includes the following steps: Step (1) 〇 1) First, an original image file is transmitted through a spectrometer and color management software, and each color of the original image file is obtained by using the chromaticity coordinate (cj E B*a*b*1976) analysis and color matching principle. Point to the coordinate position in the chromaticity coordinate map (eg, brightness (L), chroma (a, b) value); wide (1〇2) and then insert the color changing ink into the original image file to require some color change On the color point coordinates, the color point replacement is replaced (when the replacement is substituted, the principle of not affecting the overall appearance of the original image file, such as: dark color or boundary), and the color point coordinate data after the replacement is converted into one new Image file; _1 Bu 1 Factory 0 3) Then apply high-line precision printing technology, mixed with general ink color sequence on a printed material, and accurately control overprinting printing dots (printing) on the printed material Size and dot gap (at this time, the color-changing ink has been mixed with the printing ink and printed on the printing mark); thus, the method of producing a variety of color-changing effects of the color-changing ink of the invention of 200823059 is completed. In the present invention, when the color changing ink is discolored by the color changing mechanism, it will be adjacent to the overprinting color ink, and various color changing effects of color mixing can be produced to produce a desired color change; and so on, when different peripheral printing inks are used Mixed with color-changing ink, you can combine a variety of colors, such as matching dot gain, _ color sequence, color, high-precision printing lines and other control factors, you can change the multi-level, multi-color, diversified color mixture Color change effect. As for the printed materials, it refers to the printed materials that conform to the four print layouts of flat, convex, concave and net, such as paper, plastic, metal, woven fabric, etc., and the four major printing formats, which are discolored. Ink mixed printing inks also include flat, convex, concave, screen printing inks and UV light-emitting inks (
Ultravi〇letradiati〇n，簡稱UV) 〇 以下係進一步地說明當變色油墨因變色機制啟動而變色 後，會與其鄰近疊印色墨，產生視覺色彩混色之多種變化效 例如·原來變色油墨為青色，經變色機制作用後即變為 洋紅色，倘若鄰近印紋色彩為黃色系，職覺混合後即變成 為、、工色’倘若鄰近印紋色彩為藍色系，則視覺混合後即變成 為紫色，其突破了只能單-顏色或少數顏色變化之限制。 又視兔/心色之效果取決於印刷線數之精密度，印刷線 200823059 =南’代表網點（印紋）越小、越細密、色彩變化效果就 越柔和；反之’印刷線數越機，則網點（印紋）越大，變 色油墨插人於秘影側射辦_，就越魅 色效果。 藉此上述本發明之方法，只要在印刷前設定好印刷線 數、網屏肢、_ (印紋）形狀，朗先設計想要之變化 顏色’即可與變色油墨於變色前、後，產生視覺混合多樣化 之文色政果’其不僅具有低成本，尚具有高效益之優點；而 為了達到多種色彩及柔和之視覺混色效果，對於圖像來 ，I7概數、冋精細峨、網屏角度、油墨選擇、印墨墨 量、色彩減色混色上之控制需要相當地精確 ，以下係進一步 針對前述各部份進行說明： A圖像來源及印刷線數，係利用平、凸、凹、網四大印Ultravi〇letradiati〇n, abbreviated as UV) 〇 The following system further explains that when the color changing ink is discolored by the color changing mechanism, it will be adjacent to the overprinted color ink, resulting in a variety of changes in visual color mixing. For example, the original color changing ink is cyan. After the color change mechanism acts, it turns into magenta. If the color of the adjacent print is yellow, the job becomes mixed and becomes the work color. If the color of the adjacent print is blue, the color will become purple after mixing. It breaks through the limitations of single-color or a few color changes. Also depends on the rabbit / heart color effect depends on the precision of the number of printed lines, the printing line 200823059 = South 'representing the dot (print) is smaller, the finer the color, the softer the effect of color change; otherwise the 'printing line number is over, Then the larger the dot (printing), the coloring ink is inserted into the secret side of the _, the more the charm effect. According to the method of the present invention, as long as the number of printing lines, the screen limbs, and the _ (printing) shape are set before printing, the color of the desired color can be changed with the color changing ink before and after the color change. The visual mix and diversification of the color politics is not only low-cost, but also has the advantage of high efficiency; and in order to achieve a variety of colors and soft visual color mixing effects, for images, I7, 冋 fine, screen The control of angle, ink selection, ink quantity and color subtraction color mixing needs to be quite accurate.

The ink selection and printing The amount of ink is the choice of ink. The ink with high shielding rate is the first choice. In view of the demand for diversified printing materials, if the shielding rate of printing ink is not high, it is easy to be disturbed by the background color of the printed material, which will destroy the original design aesthetics. The amount of ink in printing needs to be precisely controlled. For example, lithography, through Gray replacement technology (Gray Component

The color subtractive color mixing is a high-resolution image printed on the printed material after the high-resolution image is printed, and the dense dot (printing) is superimposed on the printed material, and the density of the dot is determined by the number of printing lines; The ink will be exposed between the surrounding ink dot and the dot; when the color changing ink is changed due to the color change mechanism, the new color after the color change is displayed by the dot gap and the color difference is mixed with the adjacent dot (print) (yellow + Magenta - red, magenta + cyan - blue, cyan + yellow - green, yellow + magenta + cyan - black), whereby 'different color dots (prints) can produce different mixed colors with color changing inks' The dog breaks the original fixed monochrome to monochrome, with a few color variations, and strengthens the anti-counterfeiting color recognition mechanism. As described above, we can understand that the method of the present invention for producing a plurality of color-changing effects of color-changing inks can improve the technical application of the prior art: The effective dog can be used for fixed monochrome to monochrome and a few colors. Restrictions further achieve multiple color-changing effects that produce visual color mixing. Second, the invention can be combined with a variety of color discoloration according to the preferences of the anti-counterfeiting designer, strengthen the anti-counterfeiting color recognition mechanism, improve the technical threshold, increase the application range, and reduce the risk of counterfeiting.
