Multi-color printing plate and screen technology

The field of offset printing has been developed from the original four-color to the current multi-color printing, so as to further expand the scope of color reproduction. This paper introduces the Hi-Fi Color (eder MCS+ Super Fine Color) technology.

High-fidelity printing (Hi-Fi Color) technology

The so-called high-fidelity printing refers to the printing method jointly expressed by CMYK and RGB oils and inks. It is aimed at the case of high-precision screens with 350 to 500 lines, which can achieve the same effect as FM screening. . The advantage of high-fidelity printing is that through the common performance of CMYK+RGB, the occurrence of ink imbalance and gray component changes are avoided, thus ensuring the stability of ink printing and color reproduction.

In order to achieve high-fidelity printing technology, you need to use MCS (MultiColor Separation) software,
e der MCS and Super Fine Color
e der MCS is a software that combines CMYK and RGB to divide the image into 7 colors. It divides the 4-color image into a 7-color version, which improves the RGB color saturation and can exhibit the same effect as the spot color printing. Samples to select the color saturation and hue of RGB inks.

Super Fine Color is based on the color management using ICC files, and it is software for color separation of RGB data. Since a reproduction effect close to the original can be obtained, no problem occurs even if there is a skin color and an ash component.

Super Fine Color directly passes RGB data to RIP, that is, to CTP or image setter, and performs color conversion at the stage of the production network. In the final stage, the image can be divided into 7 colors.

Super Color Technology guarantees stable printing

Due to the inconsistent hue of the printed matter, it is difficult to compare the samples for printing. From the data management of the printing equipment to the high requirements of the operator's technical experience, all of them bring a series of difficulties to the printing of high quality and standardized products. Therefore, the Super Color Technology technology should be applied. And students. In addition, with the increasing number of images acquired by digital cameras, high-precision RGB-CMYK image conversion software is required. Since there are no ideal printing conditions, the results of the printing are different under different printing conditions. At this time, the solution to compensation is Super Color Technology, which is also the most effective means to promote printing stability. For manuscripts, high-precision color separation processing and color space conversion are achieved, and the output is as close to the original as possible, so that faithful color reproduction can be achieved.
