RGB colors cannot be used directly for printing. It has been found that printing with red, green, and blue inks has a smaller color gamut, and the color saturation of the main secondary colors is lower. A larger color gamut can be obtained when red, green and blue reverse inks, that is, cyan, magenta, and yellow inks are used. Therefore, this color becomes the plate printing color. For decades, CMYK four-color printing has become a treasure in the printing industry, and it is commonly used.
However, with the rapid development of science and technology, personalized production methods and products with higher added value have become fashionable. In the process of increasing the enjoyment of personalized services in other industries, customers of printing plants will also request personalized printing services from printing companies. However, in the traditional four-color printing field, there are no individual changes. Although there are spot colors, fluorescent colors, metallic colors and printed materials, who can add color to printed images?
Four-color printing technology has become a personalization and gentrification of color reproduction. If the printing companies do not take the initiative to break the four-color printing curse, and wait until the user rushes to leave, the loss of market share is inevitable.
Faced with the limitations of the four-color printing gamut, why not expand the color gamut? Most people now have a new printing technology called Hi-Fi Color Printing, which translates to high-fidelity color printing. Since existing papers and inks do not yet completely reproduce the color gamut of natural color originals, in order to improve the saturation of certain colors on prints, pure printing is added on the basis of the four colors of C, M, K, and K. The bright red, green, and blue-purple colors allow the printed image to produce a more natural contrast and a fresher color sense. This printing method is called high-fidelity printing. For example: When printing a picture with strawberries. Can increase the red version and green version, so that the red fruit of the strawberry and the green green of the green leaves appear more pure and realistic, and the whole picture appears vivid and vivid.
