Abstract
Disclosed is a dither matrix generating method in which halftone dots are formed by growing corresponding dots. The dither matrix generating method includes a first generating step of generating first threshold values of a dither matrix, so that the dots are grown until a predetermined halftone dot area ratio is achieved, wherein, when the predetermined halftone dot area ratio is achieved, the halftone dots contact each other; and a second generating step of generating second threshold values of the dither matrix, so that the dots grow beyond the predetermined halftone dot area ratio.
