The intention was to make a technical-looking sans with a warmer feel to it, balanced between hard geometric shapes and friendly curves with slightly narrower endings. It should be useful in a wide range of tasks, whether combining the eight weights with distinct italics for editorial design, setting multiple pages of text, making financial reports, or using the highly contrasted lights and blacks for display and packaging design.Argumentum has a character set to support Western and Central European languages, and an extended set for monetary symbols. Each weight includes small caps, ligatures, proportional lining and oldstyle numbers, tabular figures, fractions and scientific superior/inferior figures.
