Polke is a single weight display face brimming with style and charm but simultaneously exuding impressive core strength and a vibrant personality. Floating ball terminals rub shoulders with contrasting sharp and rounded letterforms to produce a distinctively decorative headline font built on robust foundations.Polke’s name is derived from the striking terminal dots which dominate the character set, creating a Polka-Dot effect throughout. I also had the artist Sigmar Polke in mind which explains the spelling, and so the two ideas simply morphed together.
