Action Text puts Erik van Blokland’s ideas about type for interfaces and reading on screen into practice, building on his previous explorations that yielded Action Condensed. Its fantastically inventive letterforms all stem directly from function: any details that couldn’t be removed were simplified and exaggerated. The family is a contemporary addition to the pantheon of great sans serifs designed for legibility at tiny point sizes and in difficult reproduction conditions. The Bright grade is preferable for knocking out text in backlit environments like screens and internally illuminated signage, while Dark holds its own under poor printing conditions and when contrast between text and background is reduced.
