  2. CMYK color model - Wikipedia

    en.wikipedia.org/wiki/CMYK_color_model

    The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation CMYK refers to the four ink plates used: c yan, m agenta, y ellow, and k ey (black).

    It was designed to encompass most of the colors achievable on CMYK color printers, but by using RGB primary chromaticities on a device such as the computer display. The Adobe RGB color space encompasses roughly 50% of the visible colors specified by the Lab color space , improving upon the gamut of the sRGB color space primarily in cyan-greens.

    Main articles: CMY color modeland CMYK color model. It is possible to achieve a large range of colors seen by humans by combining cyan, magenta, and yellowtransparent dyes/inks on a white substrate. These are the subtractiveprimary colors. Often a fourth ink, black, is added to improve reproduction of some dark colors.

    en.wikipedia.org/wiki/Color_printing

    This printing technique is referred to as CMYK (the "K" stands for key, a traditional word for the black printing plate). Today's digital printing methods do not have the restriction of a single color space that traditional CMYK processes do. Many presses can print from files that were ripped with images using either RGB or CMYK modes.

  6. RGB color model - Wikipedia

    en.wikipedia.org/wiki/RGB_color_model

    A diagram demonstrating additive color with RGB. The RGB color model is an additive color model [1] in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.

  7. Color space - Wikipedia

    This image demonstrates the difference between how colors will look on a computer monitor (RGB) compared to how they might reproduce in a particular CMYK print process. Colors can be created in printing with color spaces based on the CMYK color model, using the subtractive primary colors of pigment (cyan, magenta, yellow, and black).

  8. Spot color - Wikipedia

    en.wikipedia.org/wiki/Spot_color

    The widespread offset-printing process is composed of the four spot colors cyan, magenta, yellow, and key commonly referred to as CMYK. More advanced processes involve the use of six spot colors ( hexachromatic process ), which add orange and green to the process (termed CMYKOG ).

    In the RGB model, hues are represented by specifying one color as full intensity (255), a second color with a variable intensity, and the third color with no intensity (0). The following provides some examples using red as the full-intensity and green as the partial-intensity colors; blue is always zero: Red. Green.
