Abstract
A method of recording a color image uses both additive primary colors (that is, red, green, and blue) and subtractive primary colors (that is, cyan, magenta and yellow), as well as white and black. These eight colors are used to provide a dot matrix representing one picture element of the image, wherein each picture element is represented by a predetermined number of dots of an additive primary color, a predetermined number of dots of a subtractive primary color and, if appropriate, predetermined numbers of white and black dots. The dots do not overlap.
