Abstract
An optical printer apparatus exposes a sensitized sheet (,) to light from a light source (,), which is movable relatively to the sensitized sheet (,), with given timing in accordance with image data composed of pixels having a plurality of gradations that are linearly changeable from a minimum gradation of low color density to a maximum gradation of high color density. The distance for the exposure is adjusted for area gradation, whereby a gradated image is formed on the sensitized sheet (,). Further, change of the exposure distance, compared to change of the gradation, is not uniform throughout the range, and a non-linear relation is established between the changes.
