Abstract
A method and apparatus for recording graphic or image information by means of punctiform recording spots which are arranged line-by-line according to a recording grid, or multi-lined within a matrix, whereby at the beginning of a contour proceeding obliquely to the recording direction, the first recording spot is displaced in the direction of the contour when its edge does not coincide with the contour and, in order to improve the end edge of such a contour proceeding obliquely to the recording direction, the recording of the last recording spot may be additionally displaced relative to the preceding recording spot by a retarding in time of the recording of said last spot.
