What is high fidelity 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.
The use of high-fidelity printing increases the production costs and the technical requirements for the production process are also high. At present, high-fidelity printing is still at the research and experimental stage in China, and it is rarely used for commercial printing.
