Abstract In a printing device which prints a color image on a photosensitive material by allowing an exposing head to modulate light from a light source for each pixel in accordance with image information, the exposing head is constituted by superposing three LCS's in the light-axis direction. The respective LCS's control the transmission and interruption of only the respective blue, green and red color components so that color tones in the respective pixels with respect to an image printed on printing paper are controlled based upon the subtractive color process. Therefore, it is possible to eliminate the generation of pixel offsets in an image printed on the photosensitive material by using a simple structure, and consequently to provide a printing device having a superior processability.
