Abstract
In a multi-function printer, a scanning module reads an image of an original and generates corresponding color image data. A color converter converts a set of red (R), green (G) and blue (B) values of a pixel of the color image data into a set of cyan (C), magenta (M) and yellow (Y) values, and converts one of the two sets of values into a black (K) value. A pattern generator generates first to third sets of patterns according to the C, M and Y values, respectively. A print data generator processes the first to third sets of patterns and the K value into print data. A printing module receives the print data and prints the first to third sets of patterns on a medium in a superimposed manner. The first to third sets of patterns printed are monochrome images having darkness based on the K value.
