despite its name, the “modern” typeface, also known as didone, is not new. in the eighteenth century improvements in paper quality combined with more advanced printing methods brought about changes in how typefaces were created.
modern is the term used to categorize fonts created at that time or in the style of that time.
modern fonts are recognizable by their thin, long horizontal serifs, and clear-cut thick/thin transitions in the strokes. the stress is vertical, i.e. there is no slant on the letters.
