<p>The invention relates to the graphic reproduction of symbols on an imaging surface. These symbols can be controlled as regards position and/or scale. They are reproduced as successions of brightness values arranged in image lines. As a result of the use of brightness values between levels occurring in an ideal brightness profile of the symbol (for example, only black and white), high-resolution details are reproduced. In accordance with the invention, boundaries between successive image lines are used to reproduce transitions between the brightness levels as sharply as possible. <IMAGE></p> |
