四色印刷是一種常見的彩色印刷，但有些要求較高的四色印刷不能滿足需求，出現了專色印刷，那么四色印刷和專色印刷有哪些特點，區別在哪里，濟南印刷廠為您深入分析。
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.
這四種顏色是混合色，分別是綠、綠、黃、黑四種顏色，即C、M、Y、K，這四種顏色在PS中很常見，它們以不同的比例來分配想要的顏色和圖像。因此，在我們常見的彩色印刷機中間有四組，這就是原因。對于一些的印刷公司來說，在各種印刷生產中，可以更好的掌握印刷色彩處理的原理和方法。一般來說，在印刷三原色時，C、M、Y、K這四種顏色都有自己的彩版，在彩版上記錄著這四種顏色的網點，這些網點是由網版上的網版產生的，這四種彩版合在一起就形成了三原色的定義。北京印刷廠專色印刷底色但四色印刷的缺點是通過圖像網點的密度來調整比例，這樣的方法在重印色塊時有些色塊肉眼就能看到網點，造成色塊紋理不強。
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.
在這種情況下專色出現,來彌補這種不足,專色是由的色譜法,根據色譜的比例分配所需的油墨顏色直接印刷,顏色不需要點密度來控制,所以整個顏色是固體,看起來更紋理。專色是金色和銀色，但實際上潘通光譜中有成千上萬種專色。如果所需要的顏色不在色譜上，也可以根據色彩大師的經驗來調整所需要的顏色，來找到油墨的比例。北京印刷廠四色印刷圖片專版彩印一般在高檔書刊中起點綴作用，但多用于包裝，使印刷色彩更有質感，視覺沖擊力更強，如香煙包裝等。
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.
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.
