PURPOSE:To obtain a bordered white character by superposing a black character film which is formed bolder by one size from a character original and has a low density on a positive film, exposing the films, registering a void characteristic film thereon and exposing the films. CONSTITUTION:The black character film original 1 is superposed on a negative lith photosensitive material 12 via a diffusion sheet 11 and is subjected to contact exposing. The photosensitive material is developed by diluting a developing soln. for negative twice with water. The void character film 6 which has slightly blurred contours, is bolder by one size and has the low density is obtd. when the photosensitive material is finished to 0.30 density in the photosensitive part. The character part is white and the edge has the density higher than the background density if the black character film original 1 and the void reversal character film 6 having the blurred contours, 0.30 density, the character bolder by one size and the low density are superposed on a negative film original 12 and these films are subjected to contact development. The bordered white character is obtd. in this way. |
