Erik Spiekermann, working in collaboration with Ole Schäfer, originally designed FF Info® Display for use in the context of wayfinding systems. The variants FF Info™ Text and FF Info™ Correspondence were developed later for text setting and office communication. FF Info Display The sober and clear forms of the sans serif FF Info Display have been deliberately molded to make them perfect for use on wayfinding systems. The font by Ole Schäfer and Erik Spiekermann not only takes the problem of lack of space into account - it is some 15% narrower than comparable typefaces - the characters have also been designed to ensure they remain legible even in adverse conditions for reading. As text on signs often contains words with which readers are unfamiliar and which are thus deciphered letter for letter rather than perceived as whole words, it is essential to provide for a clear differentiation between glyphs. Additional serifs on the lowercase "i" and uppercase "I" and a small arch on the terminal of the lowercase "l" ensure that it is possible to readily discriminate between these particularly problematic letters. Moreover, sharp corners on glyphs can also make it difficult to read signs with backlighting or when driving past. The rounded corners of FF Info Display counteract this effect and make sure that the character forms remain well defined.FF Info Display is available in five carefully coordinated weights, from Regular to Bold. In the corresponding italic variants, the letters appear overall more rounded while the lowercase "a" has a closed form and the "f" has a descender. Also included among the glyphs of FF Info Display are several ligatures and arrow symbols. Pictograms with different themes that complement the typeface are also available in four weights. FF Info Text Thanks to his know-how gained through designing other typefaces, Erik Spiekermann became aware that fonts created for use in problematic environments can be used in many different situations. In smaller point sizes, FF Info Display cuts a fine figure when used to set longer texts. So Spiekermann carefully reworked FF Info Display to produce FF Info Text, a font perfected for use in this context. Not only can the characters be more generously proportioned, certain features, such as additional serifs to aid with the differentiation of problematic letters, are also no longer necessary in textual surroundings. The upright styles have a double-story "g" while Spiekermann has added oldstyle figures and small caps. FF Info Correspondence FF Info Correspondence has also been designed for setting block text although it recalls the style of old typewriter characters and is specifically intended for use in office communication. The characters of this third member of the family are thus more formal, without rounded terminals but with rectangular punctuation marks. The narrower letters are provided with large serifs to give them more space although, at the same time, this reduces the differences in terms of letter width among the alphabet. In contrast with its two siblings, FF Info Correspondence has only three weights, each with corresponding italic.The three styles of the FF Info super family cover an extensive range of potential applications. If the different kerning is adjusted manually, the three styles harmonize happily with each other and can be readily used in combination to set, for example, headlines and texts and also creative display options.
