Abstract
A method and an apparatus of exposing a photosensitive medium for forming thereon a latent image which corresponds to an original image to be reproduced and which is developed into a visible image. The photosensitive medium has a basic minimum amount of exposure to a radiation, below which a density of the visible image remains constant and above which the density varies with an amount of exposure to the radiation. An entire recording surface of the photosensitive medium is evenly exposed to a first radiation by a predetermined first exposure amount determined by the basic minimum amount, and each label area of the recording surface is exposed to a second radiation by a second exposure amount which corresponds to a density in a corresponding local area of the original image, so that the first and second exposure amounts cooperate to form the latent image.
