  四色印刷是一种常见的彩色印刷,但有些要求较高的四色印刷不能满足需求,出现了专色印刷,那么四色印刷和专色印刷有哪些特点,区别在哪里,济南印刷厂为您深入分析。

  Four color printing is a kind of common color printing, but some of the four-color printing with higher requirements can not meet the demand, and spot color printing appears. Then what are the characteristics and differences between four-color printing and spot color printing? Jinan printing factory will make an in-depth analysis for you.
  这四种颜色是混合色,分别是绿、绿、黄、黑四种颜色,即C、M、Y、K,这四种颜色在PS中很常见,它们以不同的比例来分配想要的颜色和图像。因此,在我们常见的彩色印刷机中间有四组,这就是原因。对于一些的印刷公司来说,在各种印刷生产中,可以更好的掌握印刷色彩处理的原理和方法。一般来说,在印刷三原色时,C、M、Y、K这四种颜色都有自己的彩版,在彩版上记录着这四种颜色的网点,这些网点是由网版上的网版产生的,这四种彩版合在一起就形成了三原色的定义。北京印刷厂专色印刷底色但四色印刷的缺点是通过图像网点的密度来调整比例,这样的方法在重印色块时有些色块肉眼就能看到网点,造成色块纹理不强。

  These four colors are mixed colors, which are green, green, yellow and black, i.e. C, m, y and K. These four colors are very common in PS, and they distribute the desired colors and images in different proportions. Therefore, there are four groups in the middle of our common color printing machines, which is the reason. For some professional printing companies, in a variety of printing production, can better grasp the principle and method of printing color processing. Generally speaking, when printing three primary colors, C, m, y and K all have their own color plates. The dots of these four colors are recorded on the color plates. These dots are generated by the screen plates on the screen plates. The combination of these four color plates forms the definition of three primary colors. The disadvantage of spot color printing in Beijing printing factory is to adjust the proportion through the density of image dot. In this way, when reprinting the color block, some color blocks can see the dot with naked eyes, resulting in the weak texture of the color block.
  在这种情况下专色出现,来弥补这种不足,专色是由的色谱法,根据色谱的比例分配所需的油墨颜色直接印刷,颜色不需要点密度来控制,所以整个颜色是固体,看起来更纹理。专色是金色和银色,但实际上潘通光谱中有成千上万种专色。如果所需要的颜色不在色谱上,也可以根据色彩大师的经验来调整所需要的颜色,来找到油墨的比例。北京印刷厂四色印刷图片专版彩印一般在高档书刊中起点缀作用,但多用于包装,使印刷色彩更有质感,视觉冲击力更强,如香烟包装等。
  In this case, spot color appears to make up for this deficiency. Spot color is directly printed by professional chromatography, according to the proportion of chromatography, the ink color required for distribution is directly printed, and the color does not need point density to control, so the whole color is solid and looks more textured. Spot colors are gold and silver, but actually there are thousands of spot colors in Pantone spectrum. If the required color is not on the chromatogram, you can also adjust the required color according to the experience of the color master to find the proportion of ink. The special color printing of four-color printing pictures in Beijing printing factory is generally used in high-end books and periodicals, but it is mostly used for packaging, making the printing color more texture and visual impact stronger, such as cigarette packaging, etc.
  辨别四色和专色的方法很简单,那就是用放大镜去看印刷的网点,专色就是不看网点。济南印刷厂的人员不用放大镜就能用肉眼分辨四种颜色和专色。本文来源:http://www.jnurs.com,转载请注明出处。
  The way to distinguish four colors and spot color is very simple, that is to use a magnifying glass to see the printing dot, spot color is not to see the dot. The professionals of Jinan printing factory can distinguish four kinds of colors and spot colors with naked eyes without magnifying glass.
