IBM Plex is an open source typeface superfamily conceptually designed and developed by Mike Abbink at IBM in collaboration with Bold Monday to reflect the design principles of IBM and to be used for all brand material across the company internationally. Plex replaces Helvetica as the IBM corporate typeface after more than fifty years, freeing the company from extensive license payments in the process.[1]
Version 1.0 of the font family had four typefaces, each with eight weights (Thin, Extra Light, Light, Regular, Text, Medium, Semi-bold, Bold) and true italics to complement them.[2]
''i'', ''j'', ''t'' and ''x'' letters.As of version 1.0 the IBM Plex typefaces support over 100 languages with most that use the Latin alphabet (including Vietnamese), as well as Cyrillic (except in IBM Plex Sans Condensed). In version 3.0 of IBM Plex Sans, support for monotonic Greek was added.[3] For other writing systems separate fonts were made without italics:
In addition, both Mike Abbink and Bold Monday have confirmed to be working on support for CJK, Bengali, Tamil and Kannada.[10] [11] [12]
There is also support for common mathematical and currency symbols (including Bitcoin (₿) #U+20BF which was ratified into Unicode in 2017) as well as ligatures such as fi and fl, along with stylistic alternates for a, g and 0.
There are a few unreleased symbols for IBM Plex Sans Condensed, IBM Plex Mono and IBM Plex Serif such as the generic currency sign (¤), prime symbol (′) and double prime symbol (″). In addition Mike Abbink has confirmed support for the Mathematical Operators block and support for the symbols used in the APL programming language in 2019.[13] [14]
The FCC #EFCC and CE marking #ECE0 logos are encoded as glyphs within the Private Use Area.[15] Prior to version 1.0, five IBM logos (solid and 8-bar logos, and the I-Bee-M logo) #EBE1 to #EBE7 were also encoded as glyphs.
IBM has licensed the font files only under the SIL Open Font License (SIL OFL).[16] Between 9 August 2018 and 21 August 2018, the fonts were also dual-licensed under the Apache License. This dual-licensing arrangement was rescinded due to concerns that the Apache License is unsuitable for fonts.[17] The SIL OFL license is free and open-source, but building the fonts from source requires FontLab Studio, which is proprietary software.[18]
Bold Monday also provide web development code in CSS, SCSS and JavaScript that is related to the fonts under the Apache License.[19]
IBM Plex's name is reserved, as allowed by the SIL OFL, and trademarked as of December 2017.[20] [21]
