Since by now almost every classic rule of typography is slowly becoming obsolete (or, more precisely, design now follows different rules and creates new forms), it is not the Leipzig rule of line arrangement, the mixing of typefaces or the principle of the golden ratio that I consider important to observe. As the one carrying out the printing, I have to attach greater importance to the technical parameters. Computers and software are now available to everyone, and a significant share of publications is produced not through typographic design but by desktop publishers. There are, to be sure, colleagues with a good eye who work carefully and beautifully, but a mouse does not punish its incompetent user the way a chainsaw or a rotary tiller does... Let's not forget that typography and desktop publishing are not ends in themselves: they have to support the function of the printed product. So a business card cobbled together in CorelDraw! and printed with rainbow lettering on a flowery meadow is just as much garbage as a table that can't be filled in because its fields are tiny, an ad forced into the size of a matchbox with 5-point, thin, condensed type, or a brochure that ignores the holes needed for spiral binding and is therefore missing letters.
