Generation of typefaces on high resolution output devices

A method for generating the output of character fonts on high resolution output devices including a separate processor unit, an interim storage for font data to be output and an output unit which transfers data received from the interim storage directly onto a multiplication medium, wherein the separate processor unit expands and condenses a digitally stored font before sending it further to the interim storage, said method comprising the steps of:

• 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 font scaling instructions, and re-scaling the master font with a factor to the desired point size, and
• utilizing the instructions to hold letter stroke thickness constant during the expansion or condensation of letters and in this way only to broaden or narrow the inner counters.

A method for generating the output of character fonts for high resolution output devices including a processor for re-scaling a master font digitally stored in a digitized contour coding with discrete control points and scaling instructions comprising,

• re-scaling characters of the master font to a desired point size and,
• applying instructions to monotonically vary the character stroke width of the re-scaled characters with a pre-set factor dependency that is a function of the desired point size wherein a character stroke width is increased for factors smaller than one and is decreased for factors greater than one.
