This invention relates to a method of controlling light intensity in connection with the exposure of photosensitive material in an imagesetter/platesetter, which comprises a light source for illuminating said photosensitive material, wherein the light intensity of said light source is increased to a predetermined level ensuring a sufficiently steep transition between exposed and non-exposed material, and random image information representing material for exposure is modified so as to reduce the time during which the light source is active. The invention also relates to an apparatus for the same. A method and an apparatus eliminating/reducing the phenomenon spot wear are provided hereby. |
