Color Printing

Color printing or Colour printing is the reproduction of an image or text in color (as opposed to simpler black and white or monochrome printing). Any natural scene or color photograph can be optically and physiologically dissected into three primary colors, red, green and blue, roughly equal amounts of which give rise to the perception of white, and different proportions of which give rise to the visual sensations of all other colors. The additive combination of any two primary colors in roughly equal proportion gives rise to the perception of a secondary color. For example, red and green yields yellow, red and blue yields magenta (a purple hue), and green and blue yield cyan (a turquoise hue). Only yellow is counter-intuitive. Yellow, cyan and magenta are merely the "basic" secondary colors: unequal mixtures of the primaries give rise to perception of many other colors all of which may be considered "tertiary."

Famous quotes containing the words printing and/or color:

    Before printing was discovered, a century was equal to a thousand years.
    Henry David Thoreau (1817–1862)

    It is never the thing but the version of the thing:
    The fragrance of the woman not her self,
    Her self in her manner not the solid block,
    The day in its color not perpending time,
    Time in its weather, our most sovereign lord,
    The weather in words and words in sounds of sound.
    Wallace Stevens (1879–1955)
