Color Printing: A Short History And Gimpse At What The Foreseeable future Holds
Color printing is the remaking of images or text in color which differs from more straightforward black and white format or monochrome printing. All color photographs and natural scenes can be physiologically and optically classified into three main primary colors, blue, green and red, to obtain white it requires rough equal quantities of these three. Different proportions is the thing that brings about the visual sensation of various colors, blending any two unique primary colors will give you the effect of a secondary color. To illustrate red and blue produces magenta (a purple hue), red and green gives you yellow whilst green and blue yields cyan (a turquoise hue) similar to the CYMK color model. The color yellow is counter intuitive. Magenta, cyan and yellow are the basic secondary colors. Blending unequal primary colors will give rise to a perception of many different colors that are mainly considered tertiary.
