海报印刷设计 彩色印刷与多色印刷

文章作者:华政印务 发布时间:2022-10-17
一款海报,不仅但从它的设计创意和排版上比较,海报印刷也是它们争锋的战场。海报从手绘进入机器印刷时代后,在早期一直是黑白两色,直到后来才又出现了彩色印刷与多色印刷技术。
A poster, not only from its design creativity and layout comparison, poster printing is also their battleground. Posters entered the era of machine printing from hand painting. In the early days, they were always in black and white. Until later, color printing and multi-color printing technology appeared.
彩色印刷的概念是针对黑白印刷,或是单色印刷的概念而言,是用彩色方式复制图像或文字的复制方式。它包括了许多步骤,或称转换过程,才能产生高质量的彩色复制品。
The concept of color printing refers to the concept of black and white printing, or monochrome printing, which is the reproduction of images or characters in color. It involves many steps, or conversion processes, to produce high-quality color reproductions.
多色印刷,英文学名为 polychrome printing 。是指一个印刷过程中,在承印物上印刷两种及两种以上的墨色。
Multicolor printing, known as polychrome printing in English. It refers to printing two or more ink colors on the substrate in a printing process.
当前,数码印刷的主角CtP,可以获得稳定的网点大小的同时,遇到多色印刷时要想到AM加网的细线和FM加网,抑或是它们的组合,都离不开印刷机的套准精度要求。至于印刷机,需要的是能一次通印下来,为此要与所用的油墨色数等同的印刷机组才好。就是说,如果用7种色墨印刷,印刷机也是有7个机组才行,为此多色印刷机应运而生。目前市场已经有单张纸胶印机多至12机组的印刷机出售。
At present, CtP, the leading role of digital printing, can obtain a stable dot size. When encountering multi-color printing, it is necessary to think of AM screening fine lines and FM screening, or their combination, which cannot be separated from the requirements of the registration accuracy of the printing machine. As for the printing machine, what is needed is that it can be printed at one time. Therefore, it is better to have a printing unit with the same color number as the ink used. That is to say, if seven kinds of color ink are used for printing, the printing machine also has seven units, so the multi-color printing machine came into being. At present, there are as many as 12 sheet fed offset presses on the market.
一直以来,是以CMYK+175线AM加网作为标准的印刷方式。四色制版胶印(processcolor)几乎风靡了近半个世纪,随着数码相机提供的原稿增多和彩色喷墨印刷的普及,一种不同于4色制版彩印的多色印刷技术(multicolor)进入了实用市场领域。具体地说,它是将彩稿分为6版的hexachrome(六色印刷)和分成7版以上的superfinecolor(超精细彩印)。
CMYK+175 line AM screening has always been the standard printing method. Four color plate making offset printing has been popular for nearly half a century. With the increase of originals provided by digital cameras and the popularity of color inkjet printing, a multi-color printing technology different from four color plate making color printing has entered the practical market. Specifically, it divides the color manuscript into six versions of hexachrome (six color printing) and more than seven versions of super fine color (super fine color printing).
所谓的进入实用市场领域的多色印刷,乃是具有6色乃至7色的高度色彩再现性的processcolor。多色印刷之所以能很快发展起来,根因在于它能以四色制版印刷的CMYK数据为基础实现了宽广的色调范围,也就是说,色域比起CMYK数据更加扩大了,甚至于把原稿上没有的色都衬托出来。
The so-called multi-color printing that enters the practical market field is a highly reproducible process with 6 or even 7 colors. The reason why multi-color printing can develop rapidly is that it can achieve a wide range of tones based on the CMYK data of four-color plate printing, that is, the color gamut is more expanded than the CMYK data, and even sets off the colors that are not on the original.
