PURPOSE:To prevent a boundary between plural picture elements from being a straight line and to obtain soft image quality by providing a light shielding mask where a hexagonal aperture window is formed. CONSTITUTION:This recorder is provided with a light source for exposing a photosensitive recording medium, a light valve panel(LCD) which is arranged between the photosensitive recording medium and the light source and which has the light shielding mask around the picture element, and a means for exposing the photosensitive recording medium to the light from the light source through the LCD. Then, a means which has the light shielding mask 53 where the hexagonal aperture window 54 is formed and relatively and finely moves the LCD and the photosensitive recording medium is also provided. In such a case, when the 1st three-color exposure is finished, the LCD is moved by (a+a')/4 in an X direction and the photosensitive recording medium is moved by (b+b')/2 in a Y direction, and 2nd exposure is performed. Next, the LCD is moved by (a+a')/4 in the X direction and the 3rd exposure is performed, then the LCD is moved by-(a+a')/4 in the X direction and the photosensitive recording medium is moved by-(b+b')/2 in the Y direction and 4th exposure is performed. |
