CMYK color mode

The basis of the CMYK color mode is not to add light, but to subtract light. in RGB mode, colors are created by adding light. A Monitor (or a TV) is a light source that can create colors. however, a print paper does not emit light; it only absorbs and reflects light. therefore, when you want to convert the monitor color to paper, you must use another color mode CMYK. CMYK is the basis for four-color printing. The four-color processing printing is mainly used to print continuous color images (such as digital photos) on a printer ). during the four-color printing process, the color is produced by using four different four printed weights on a printing press; the four different printed panels are C (cyan blue), m (magenta ), y (yellow), and K (black is represented by K, because B may also represent blue ). since the printed paper cannot emit light, the printing press cannot use RGB color for printing; instead, it uses some ink that can absorb specific light wavelengths and reflect other wavelengths. by combining cyan, magenta, and yellow ink, a commercial printer can replicate the important parts of the visible spectrum color. theoretically, 100% of blue, 100% of magenta, and 100% of yellow must be combined to produce black. however, because the ink is not pure, Blue, Magenta and yellow, the mixed color is not black, but a fuzzy brown. as a result, print workers often add black to blue, magenta, and yellow to produce dark and gray parts of the image. note that a base color is generated when the two colors are mixed. to show you the CMYK color mode, first switch to CMYK color spectrum. to do this, you need to tap the mouse on the pop-up menu arrow of the picker palette and select the color bar in the pop-up list. when the color bar dialog box is displayed, select C Myk spectrum in the style pop-up menu. you may notice that the CMYK color is darker than the RGB color.

How to Use the CMYK slider in the picker palette to change the color.

First, you need to press the mouse on the pop-up menu arrow of the picker palette to switch to the CMYK color slider. drag the Mac user to the CMYK scyclers option (PC User: Click CMYK scyclers ). on the picker palette, you will also see some differences between the RGB and CMYK color palette. first, CMYK uses four slide instead of three. each color reduction has a slide: C is for the blue color, M is for the foreign red, Y is for the yellow, K is for the black. also, these colors are measured in percentages. the percentage provides a standard way to transfer different ink color values from the design room to the printing press. CMYK percentage may be confusing, but it helps users understand this, that is, users can use CMYK percentage to generate the base color. when users know how to generate red, green, and blue from CMYK values, they can better grasp the aspect ratio when mixing colors or changing colors in this color mode. to help you create these colors, it is useful to have a color wheel in your hand. in a color wheel, colors are arranged in a circle to show the relationship between each other. the base color is arranged along the circle, and the distance between them is completely equal. each color is located between two base colors. in this arrangement, each color is directly opposite to its complementary color, and each color in the wheel is between the two colors that produce it. by learning the color wheel, you can see that the yellow and the foreign red are red together. if you subtract the yellow and the foreign red, the red is deleted. in this way, if you want to subtract red from an image, you only need to reduce the percentage of yellow and foreign red. another thing to remember is that, in color, if a user adds a color to an image, it is actually subtracting its complementary color. for example, when a user redens an image, the user actually reduces the percentage of the blue color (the blue color is a complementary red color, which is directly opposite to each other in the color wheel ).
