Multi-color printing versioning and screening technology

<

The field of offset printing has developed from the original four-color to the current multi-color printing, in order to further expand the range of color reproduction. This article introduces the technology of Hi-Fi Color (eder MCS + Super Fine Color).

Technology for realizing high-fidelity printing (Hi-Fi Color)

The so-called high-fidelity printing refers to the printing method jointly expressed by CMYK, RGB oil, and ink. It is for the case of high-definition dots with a screen number of 350 to 500 lines, so that the same effect as FM screening can be obtained. . The advantage of high-fidelity printing lies in the common performance of CMYK + RGB, to avoid the occurrence of ink imbalance and changes in gray components, thus ensuring the stability of ink printing and color reproduction.

In order to achieve high-fidelity printing technology, it is necessary 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, and divides the 4 color image into 7 color versions, thereby improving the RGB color saturation, which can present the same effect as spot color printing, and can also target Samples to choose the color saturation and hue of RGB ink.

Super Fine Color is a software for color separation of RGB data based on color management using ICC settings file. Because the reproduction effect close to the original can be obtained, even if there are skin color and gray components, there will be no problem.

Super Fine Color directly transfers RGB data to RIP, that is, the data is transferred to CTP or image integrator (image setter), and the color conversion is performed at the stage of production outlets, and the image can be divided into 7 colors at the final stage.

Super Color Technology to ensure stable printing

Due to the inconsistent color tone of the printed matter, it is quite difficult to print according to the sample. 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 printing high-quality and standardized products. Therefore, the Super Color Technology technology should be applied. Born. In addition, with the increasing number of images acquired through digital cameras, it is necessary to have high-precision RGB-CMYK image conversion software. Because there is no ideal printing conditions, the printing results are different under different printing conditions. At this time, the solution to compensate for it is Super Color Technology, which is also the most effective way to promote printing to achieve stability. For the original, through high-precision color separation processing and color space conversion, the output is as close as possible to the original, and faithful color reproduction is achieved.
