Many typefaces designed with a pen on paper (especially those from the 20th century) were licensed by different foundries, and were later independently digitized by them. Some special characters such as @ or the euro sign, were independently added later. Those “alternate cuts” are different digital versions of basically the same typeface design. They often vary in character set, letter proportions and kerning. Some are published under different names.
Serifa was designed by Adrian Frutiger for the Bauer foundry in 1967. The letterforms are based on those of Frutiger’s earlier sans serif design, Univers. Square, unbracketed serifs have been added, making this a slab serif (or Egyptian) typeface.
Developed by Adrian Frutiger for Bauer in 1966, Serifa is a slabserif based on the principles that led to the success of Frutiger’s 1956 sanserif, Univers. Glypha, designed by Frutiger for Stempel in 1979, is a version of Serifa with a moderately larger x-height; Stempel has paid royalties on Glypha to Neufville since 1984.
