With open and advanced tools, R&D personnel can evolve the color separation theory they have mastered into a practical color separation model that can be used in actual production. The use of different base color inks to design color separation models with different personalities and realize the printing and reproduction of unique color features is no longer a difficult task. The modern society has entered an era of advocating personalization. Personality attracts attention to a much higher degree than simple, repeated effects, because it shows courage and wisdom. The wave of personalization of modern industrial products and services is intensifying because of the huge business opportunities. Printed products can realize the duplication of personalized colors, and will give those outstanding advertising designers and forward-looking users of print products a more effective new stage for unique creativity and display of corporate ideas. While helping them introduce themselves and their products to the society in a brand-new attitude, printing companies can also enjoy fame and fortune.
The high-fidelity color printing technology can realize the personalized color printing and copying function, and after the proper adjustment of the color separation model, it can also form a high-fidelity color anti-counterfeiting function. Anyone who uses high-fidelity anti-counterfeit prints to make copies of originals can easily and accurately identify them. Each high-fidelity color anti-counterfeit technology solution includes a security color separation model and dozens of color passwords, each of which is different from each user. For example as shown below:
The color password is determined by using the same overprinting dots of printed color vision and different metameric characteristics. In the conventional four-color printing, the basic color inks used are basically the same, and the color separation model is basically the same. Therefore, regardless of the manufacturer or the copy maker, the ink dots generated by one color separation are basically the same. Original prints and imitations are difficult to accurately distinguish between visual effects and dot formation. A large number of fake and shoddy products are using the conventional four-color printing technology.
High-fidelity color printing products have a remarkable "one-line security" function compared with conventional four-color printing products. High-fidelity color anti-counterfeit prints, each of the color separation models used are exclusively customized by users. Compared with other users' high-fidelity anti-counterfeiting technology solutions, the probability of repetition of color passwords is one billionth of a billion. Has a real sense of "second-line security" function. The use of special inks is designed to increase the difficulty of imitation. In the design of anti-counterfeit products, the colors of the passwords can be skillfully combined and designed into different patterns, or distributed in different parts so that the copyists can not easily perceive and analyze them. You can also use high-resolution printing dot size and shape changes, network cable frequency combinations to increase the technical characteristics of color passwords, which can further increase the difficulty of imitation. In the current social situation in China, when the color effects of packaging prints have changed dramatically, which has a powerful role in promoting product sales, if there is also a reliable anti-counterfeiting function, this printing technology will undoubtedly have a huge market demand. Both print users and printing companies will gain considerable commercial benefits.
The key technologies for high-fidelity color separation include digitalization of ink color, color separation within the ink printing color gamut, color separation outside the ink printing gamut, decomposition of color components in the color, and neutral ash components. Technological principles such as the quantification of print colors and quality evaluation have become issues of concern.
