The first one CMYK The visual color of the printer refers to the colors Cyan, Magenta, Yellow (Yellow) and Black (Key). However, RGB initials refer to, as we are sure you know, colors Red (Red), Green (Green) and Blue (Blue). Both color spaces are able to produce everything the colors that we want But they do it differently. Because while the CMYK color display is an active space, RGB adds up.
What is a functional and complementary color space?
Space for active color It is one where colors are created by mixing different inks. Each of these buttons is responsible for removing the wavelength. White, a base that reflects all waves of different colors.
For example, when we draw a red apple, we don't see that color because the apple emits it. However the colors from the image absorb all the wavelengths except the red, which is reflected by what we see with our eyes. Also, in this color space, by mixing its three colors, a near-black color is achieved (this is one of the weaknesses of this color space).
By cons, space for input color It's just a subtractive start. In this color space, we start with the basic black color. And it adds brightness and light, based on different colors. In fact, in this area of color, where the three main colors are combined, a white color is formed.
As described above, a CMYK color space is selected to work inside printers Since the objects to be represented the image is already in the previous color. While RGB is the preferred color space for monitors. As the picture is guessed from the lack of color, it's dark.
Bad for the CMYK color space
Although the CMYK color space is able to produce many colors, it still has one discomfort in front of the RGB. For example, as we mentioned earlier, a combination of 3 colors cannot produce pure black. This forces the printers to install a extra black cartridge. Only in this way will they be able to reproduce this color in the form that is necessary for printing.
Another misconception is, since vivid color It is somewhat smaller than the RGB, some industrial printers have to include special color cartridges, made specifically for that printing.
