色彩模式的介紹

1. R  G  B 模式:
RGB是由紅綠藍三原色所組成的色彩模式,我們再電腦螢幕上所看到的顏色,
就是由RGB三種顏色所混合成的。這種模式所呈現顏色的色彩比較亮、
也比較鮮艷。


2.  C  M  Y  K 模式:
CMYK是分色印刷時所用的是的基本顏色,也就是所謂的印刷油墨四色。
分別是指青(Cyan)、洋紅(Msgenta)、黃(Yellow)、黑(blacK),
一般來說,若是要印刷輸出的作品,會先轉成這個模式。

sorry i can't type chinese on this computer...

RGB mode is used in device that using LIGHT to show colour,
such as: monitor, projector, etc.
when 100%R 100%G and 100%B mixed together, it'll become WHITE

RGB is called ADDITIVE colour

CMYK mode is used in device that using INK to show colour
such as: printer, press, paint (watercolour and marker are good example)
when 100%C 100%M 100%Y mixed together, it'll beomce BLACK < but this is only in the theory
actually it's only a dark brown colour.
so BLACK (K) is added to get the REAL black colour, and also avoiding too thick of ink film on the paper (that will be another topic)
CMYK is called SUBTRACTIVE colour

For printing we're using CMYK is because the press is using INK to print but not LIGHT
of cause you would say I can use RGB INK to print, yes u can do that but the result is you'll only can print very few number of the colours out of RBG, however using CMYK u can print millions of colours. so u know the differences.

Hope it helps
u can email me if u have any other questions

SHould be CMYK

印刷四分色模式是彩色印刷時採用的一種套色模式,利用繪畫的三原色原理,用四種顏色混合迭加形成各種複雜的顏色,四種標準顏色是:

C=青色
M=品紅色
Y=黃色
K=黑色
品紅加黃色會形成紅色;品紅色加青色相成藍色;青色加黃色相成綠色;理論上只用上述三種顏色迭加就可以形成黑色,但實際印刷時三種顏色的迭加只能形成一種深灰色或深褐色(因為油墨里含有雜質的緣故);另外三層顏色也不容易立即乾燥,所以不利於快速印刷;再有三層印刷需要非常精確的套印;用黑色替代三層顏色也可以大大節省成本,所以採取四種顏色的配色方法。

印刷時用黑色作為標定套版位置的顏色,所以也叫做定位(Key)套版的顏色,用K而不用B來代表黑色。免與藍色(B)混淆。

用黑色代替其他顏色的量不盡相同,取決於採取不同的印刷技術、紙張和黑色油墨的質量。由於印刷和電腦顯示使用的是不同的顏色模式,電腦一般用三原色光模式,所以在電腦屏幕上看到的圖像的色調和印刷出來的有一些差別。
