After adopting hi fi printing technology in color printing plant

  The concept of color printing has a long history. As early as the late 1990s, it began to enter the production workshop of printing enterprises from the laboratory, which marks the beginning of the printing industry into a new era of color printing. Hi-Fi Color Printing is relative to four-color printing. It improves the reproducibility and authenticity of printing color by adding red, green, blue, orange and other color inks on the basis of C, M, Y, K four-color printing. In the use of better ink for printing, due to multi-color reasons, some four-color printing in the two colors can be replaced by high fidelity in the original color, so that the color more full.

  With the continuous improvement of the pursuit of a better life in color printing factories, the requirements for printing quality are becoming higher and higher. At present, high-fidelity printing technology has been more and more used by printing enterprises. Because for color image printing, in addition to high-fidelity printing technology, there is no other technology can really expand the printing color gamut of the image, so that the color of the image is brighter and more vivid, closer to the natural scene viewing effect, to achieve the printing quality level. Hi Fi color separation technology is the foundation of high fidelity printing and the key guarantee of printing quality. Since high-fidelity printing uses more than four-color ink to copy the original, the conventional color separation method is no longer suitable.

  After adopting hi fidelity printing technology, Dalian color printing plant will carry out multicolor color separation of the manuscript. The specific chromatic number is determined according to the specific conditions of the manuscript. The characteristic values of the ink products of different ink manufacturers are different, and the color separation system established therefrom is also different. Color separation software can establish different color separation systems according to the needs of products and printing. At present, there are six color separation, seven color separation and even more color separation systems. This technology is more complex than four-color separation technology. High-fidelity separation technology is the core of high-fidelity printing technology. High-fidelity separation is carried out in CIERGB color space. Input RGB color will get closer to the brightness and chromaticity characteristics of spectral color. Different combinations of base color inks match different input colors in different color range. Color and chroma parameters.
