Abstract
A graduation reproduction method in performing the halftone recording due to screen percentage by a light spot of a light beam with the light beam being intensity-modulated on the basis of digital image data in accordance with a binary recording technique. An illumination time value is reduced with respect to the normal illumination time value determined under a recording condition set to record a minimum recording dot on the recording medium. The reduced illumination time is set as a unit illumination time at the time of the recording of the halftone and the secondary scanning speed is reduced in correspondence with the rate of reduction of the unit illumination time relative to the normal illumination time value. Further, in the case that the recording operation is the screen percentage to be effected by the light spot only for the unit illumination time, the exposure is arranged so as not to be effected by the light spot, or arranged to be effected for the normal illumination time value.
