Calamus (DTP) use optical kerning, where the shapes of the characters are analysed to determine the appropriate distances; Calamus’ approach might be regarded as a simplification of that, working with a low-resolution version of the final character. Calamus (DTP) Calamus is a desktop publishing application, built for the Atari ST computer. The first version was released on July 1, 1987 by the former German software company DMC GmbH. Calamus is still supported by its German owner company, invers Software, and also runs under a built-in and transparent Atari emulator on Windows, or on other platforms such as Mac OS 9 and Mac
