Abstract
A printing apparatus for printing a colored mark in a colored dot pattern on a colored light sensitive material which is moving. A plurality of picture element display sections are aligned in a row perpendicular to the direction of movement of the colored light sensitive material, each of the plurality of picture element display sections emitting a single colored dot, and selectively emitting light to form a dot pattern. Each of the picture element display sections comprises a plurality of sources of lights of different colors, and a plurality of light guides for transmitting the respective colored lights. The outlet ends of the plurality of light guides are regularly arranged so that the light guides transmitting different colored lights are adjacent to each other, thereby mixing the different colors of lights. By changing the intensity of the light sources, a colored dot having the desired color and intensity is produced.
