你知道高保真印刷技术吗?

  早在上世纪90年代末就开端从实验室走入印刷企业的生产车间,这标志着印刷业开端跨入了一个崭新的五颜六色印刷年代。

  As early as the end of the 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 colorful printing.
  高保真印刷(Hi-Fi Color Printing)是相对于四色印刷而言的,通过在C、M、Y、K四色印刷的根底上添加红、绿、蓝、橘黄等色彩油墨的方法来改进印刷色彩的再现性、真实性。在选用更好的油墨进行印刷时,因为多色的原因,有的四色印刷中的两次色就能够用高保真中的原色来替代,使色彩更丰满。跟着人们对美好生活寻求的不断进步,对印刷品质量的要求也越来越高,现在高保真印刷技能已越来越多地被印刷企业所使用。因为对五颜六色图像印刷而言,除了高保真印刷技能,还没有其他技能能够真正扩展图像的印刷色域,使图像色彩愈加亮堂艳丽,更挨近自然界真实景象的观看作用,到达高的印刷质量水平。
  High-fidelity 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 ink on the basis of C, M, Y and K four-color printing. When selecting better ink for printing, because of multi-color reasons, some two colors in four-color printing can be replaced by the original color in high fidelity to make the color fuller. With the continuous progress of people's pursuit of a better life, the requirement for printing quality is also getting higher and higher. Nowadays, high-fidelity printing skills have been increasingly used by printing enterprises. For colorful image printing, in addition to high-fidelity printing skills, there is no other skill that can really expand the color gamut of the image printing, make the color of the image more brilliant, more close to the viewing effect of the real scene in nature, and reach the highest level of printing quality.

  高保真分色技能是高保真印刷的根底,是印刷质量的要害保证。因为高保真印刷选用多于四色的油墨来仿制原稿,因此常规的分色方法现已不适合。选用高保真印刷工艺后,将对原稿进行多色分色。详细色数依据原稿的详细情况确定,不同油墨厂家的油墨产品特性值不同,由此树立的分色体系也有所差异。
  High-fidelity color separation technology is the foundation of high-fidelity printing and the key guarantee of printing quality. Because high-fidelity printing uses more than four-color ink to copy the original, the conventional color separation method is no longer suitable. After selecting high fidelity printing technology, the original will be multi-color separation. Detailed chromatic number is determined according to the details of the original manuscript. The characteristic values of ink products from different ink manufacturers are different, and the color separation system established by them is also different.
  分色软件能够依据产品和印刷的需要树立不同的分色体系。现在已有六分色、七分色甚至更多的分色体系。这种分色技能比四色分色技能更杂乱,高保真分色技能是高保真印刷技能的中心,高保真分色在CIERGB色彩空间中进行,输入的RGB色彩将取得更挨近光谱色的亮度和色度特性,不同的基色油墨组合别离匹配不同色相区间的输入色彩色度参数。
  The color separation software can set up different color separation systems according to the needs of products and printing. Now there are six, seven and even more color separation systems. This kind of color separation skill is more messy than four-color separation skill. High-fidelity color separation skill is the center of high-fidelity printing skill. High-fidelity color separation is carried out in CIERGB color space. Input RGB color will achieve brightness and chroma characteristics closer to spectral color. Different base color ink combinations will match different input colors in different color phases. Color parameter.
  基色油墨分色通道的设置保证印刷色彩到达印刷色域和实现阶调线性。与四色印刷比较,高保真印刷色彩在必定程度上并不因为饱和度进步而亮度降低,这是常规四色印刷底子无法做到的。现在已知的高保真分色模式主要有两类。一类是以ICISS为代表的在交互式图形界面设置分色模型,另一类是以Pantone Hexarome为代表的高保真色彩查找表(CLUTs)固定分色模型。
  The setting of color separation channel ensures that the printing color reaches the printing gamut and realizes the step linearity. Compared with four-color printing, high-fidelity printing color does not decrease in brightness due to the improvement of saturation to a certain extent, which can not be achieved by conventional four-color printing base. There are two main types of high fidelity color separation modes known now. One is to set up color separation model in interactive graphical interface represented by ICISS, the other is to set up fixed color separation model in high fidelity color lookup table (CLUTs) represented by Pantone Hexarome.
