Francker is a sans-serif typeface family based on clean and simple principles of design. The letterforms' curves are inspired by the "super ellipse," a mathematical shape that is about halfway between an ellipse and a rectangle. Francker's lowercase letters appear somewhat reduced, as the a, b, n and u have no spurs. The family is available in nine weights, from Extra Light to Extra Black. Excellent areas of use for Francker signage, posters, magazines, advertisements, or logos; wherever a timeless, modern look is needed. Francker's fonts have a large character set that includes all glyphs in Linotype's W1G specification (World Glyph Set 1). Proportional figures are available as alternatives to the tabular defaults, via an OpenType feature. The Francker type was developed designed by Anders Francker (b. 1972), an engineer and designer living in Denmark.
