To sum up, the new color printing technology research includes two parts. One is high-definition technology with the main goal of improving the delicateness of printed products; the other is high-fidelity technology with the aim of expanding the color gamut of the printing.
The high-definition technology mainly solves the problem that the scale and the level of the manuscript are reproduced by the screening method when the manuscript is continuously copied, and the scale of the dot is coarse, and the dot network is poor in expression.
High-definition technology, the use of finer dots is the only way to improve the fineness of the product, and high-grade ink is an important condition for high-definition printing. The high-fidelity color printing technology is to solve the problem of four-color printing fixed and too narrow. Among them, the key technology is to maximize the color gamut, select the appropriate ink to match the printing color gamut, achieve the best matching with the hue of the input color gamut, and optimally match the brightness and saturation to accurately achieve neutral gray balance control and color balance control. This matches the output color gamut with the input color gamut.
Proprietary high-fidelity color printing technology can produce color anti-counterfeiting effect. Therefore, the application of high-fidelity technology can tailor color matching models for customers' printing products, and provide a full set of encryption technology so that the printed products can completely prevent others from counterfeiting. This is because the optional process parameters for the matching process are so large that the probability of correct matching using non-proprietary technology is almost zero when the process parameters are not disclosed.
