Lee was an advertising design director and designed Impact with posters and publicity material in mind. Its thick strokes, compressed letterspacing, and minimal interior counterform are specifically aimed, as its name suggests, to "have an impact". Impact has a high x-height, reaching nearly to three-quarters the capital line. Ascenders are short, and descenders even shorter. With narrow apertures and folded-up letterforms, the lower-case can be quite hard to read printed small, especially for people with vision problems. The face is intended for headlines and display use rather than body text. As a display design, it was not released with an italic or bold weight. During the 1960s, there was a trend towards condensed, bold, "industrial" sans-serifs like Schmalfette Grotesk and Compacta, largely pioneered by West GermanmagazineTwen, and Impact was intended to fit this trend. Writing in 2004, the year before his death, Lee explained that the design goal was "to get as much ink on paper as possible in a given size with the maximum possible x-height" and to provide a home-grown metal type alternative to European designs in the style, which were complicated for British businesses to license and use. Lee wrote that "many of us admired the vitality and colour of what we knew only as Schmalfette, and used it by old-fashioned cut and paste. Use was limited as it was never made in metal as far as I know, and existed then in capitals and numerals only". Other designs along the same lines from around the same period included the Letraset face Compacta, Matthew Carter's slightly earlier masthead of Private Eye, and the phototypesettingHelvetica Compressed, also by Carter and released a few years later.
Release
Released at the end of the age of metal type as phototypesetting gained popularity, it was one of Stephenson Blake's last typefaces released in metal. The design rights were acquired by Monotype, which ultimately licensed the design to Microsoft as part of a package of fonts for use with Windows in the 1980s and 1990s. The original design contained wider alternate forms for the letters 'J' and 'r', intended for letter positions at the start and end of words, which have generally not been included in digitisations. The common digitisation also simplifies the design somewhat, omitting the subtle bevelling of tittles on 'i' and 'j' and flared stroke ends seen on the original metal type release. An eccentricity preserved in the digitisation is the ampersand, which is only as high as the x-height, not the cap height. Lee digitised and self-released a variant, Impact Wide, in 2002 for online sale. This release includes the alternate characters and an italic style. In July 2010, Ascender Corp introduced Impact 2010, an enhanced version with additional OpenType typographic features designed by Terrance Weinzierl and Steve Matteson. These included quirky interlocking characters, text figures and proportional and tabular figures.
