Abstract
A color printer prints a color image on photosensitive material by utilizing a digital micromirror device. The digital micromirror device is provided with four micromirror arrays constituted of plural micromirrors. The four micromirror arrays record four lines on a photographic paper at the same time while the photographic paper is successively advanced at constant velocity. Red exposure sequence, green exposure sequence and blue exposure sequence are performed in order while the photographic paper is advanced by L. Each of the exposure sequences is changed in order every advancement of photographic paper by L/3. The photographic paper passes through four lines projected by the four micromirror arrays in order. Accordingly, a pixel on the photographic paper is exposed four times at the ceiling by four micromirrors arranged on a same row for each color. Accordingly, multiple exposure is performed during advancement of the photographic paper.
