印刷普及的面很广,需要注意的问题也很多,今天着重讲一下,什么样的颜色更难印,设计时应该注意哪些要素。
The popularity of printing is very wide, the need to pay attention to a lot of problems, today focus on what color is the most difficult to print, the design should pay attention to what elements.
1、灰平衡是在一定的印刷适性下,黄、品红、青三原色版从浅到深按一定网点比例组合叠印获得不同亮度的消色(白、浅灰、灰、深灰、黑),即得到视觉上的中性灰的颜色,影响其因素很多。
1, gray balance is in certain printability, from shallow to deep yellow, magenta and green colors according to a certain proportion of the combination network version of different brightness color overprint (white, gray, gray, dark gray, black), to obtain the visual neutral gray color, a lot of influencing factors.
2、灰平衡,根据理论与生产实践的经验,印刷品更难控制的颜色就是灰平衡。
2, gray balance, according to the theory and practice of production experience, the most difficult to control the printing color is gray balance.
3、几色网点的叠加,特别是超过70%网点。具体地说,深褐色、咖啡色、墨绿色(平网、含有蓝70)、深蓝色、紫蓝色等由于存在颜色差值,在印刷机器上不易找平衡,所以都是很难印刷的颜色。

3, several color dot overlay, especially more than 70% outlets. Specifically, dark brown, brown, dark green (flat screen, containing blue 70), dark blue, purple blue and so on because of the existence of color difference, it is difficult to find a balance on the printing machine, so it is difficult to print color.

4、印刷使用的墨量、纸张、满版浓度、网点面积、叠印以及网屏线数,都会对灰平衡产生千丝万缕的影响,这是更考验机器的套印精度及操作人员技能水平的。
4, the use of printing ink, paper, full concentration, dot size, overprint and screen line number, will have a close effect on gray balance, this is the test of the machine operator and overprinter precision skill level.
5、比较难印刷的就是四色叠的漏空字。过多的多色极线细、极小字透较难印刷,对机器的叼纸牙要求极高。
5, the more difficult to print is the four color stack empty word. Color too much polar fine and very difficult to print through printing machine gripper requirements.
6、这也是较为常见的问题,所以印前设计师输出前必须检查出版物文件内黑色文字,特别是小字,是不是只有黑版上有,而在其他三色版上不应该出现。如果出现,则印刷出来的成品质量会大打折扣,RGB图形转为CMYK图形时,黑色文字肯定会变为四色黑。
6, this is a common problem, so the prepress designer output must be checked before publication file in black text, especially small, is not only the black plate, while in the other three color should not appear. If appear, then the quality of the finished product will be greatly reduced, RGB graphics into CMYK graphics, black text will become black.
7、除非特殊指定,否则必须将其处理一下。更后印刷中一般满版的东西,专色满版或面积较大,反白字,相同的标志,还有相同的色。
7 unless otherwise specified, it must be dealt with. The full version of what the final general printing, color full version or larger, anti white, the same symbol has the same color.

The printed matter is dotted with our lives, and adds a brilliant color to our lives.
