A technique is specified for the output of fonts on high resolution output devices, such as photosetters in particular. A processor unit optically scales a digitally stored font, by selecting a single master font in a digitized contour coding, in which the contours for each letter are provided with delimiting discrete control points and additionally with instructions, such as those stipulated for the "Intelligent Font Scaling"; by re-scaling the master font with a factor to the desired point size, and by utilizing the instructions in order to steadily vary the stroke thickness of the linearly re-scaled letters in a primary pre-set factor dependency, wherein the stroke thickness is increased for factors smaller than one and is decreased for factors larger than one. The font can also be typographically expanded and condensed which means keeping the widths of the vertical stems during broadening or narrowing, respectively.
