The Westminster Press was a printing company led by Gerard Meynell. The firm produced books, magazine, pamphlets, posters, and for a short period of time, printed a trade journal called The Imprint. The journal was produced by Meynell, along with Edward Johnston (who would go on to design the typeface for the London Underground Electric Railroad in 1916) and Stanley Morison (who would go on to design the typeface Times New Roman in 1932), and introduced the now-ubiquitous typeface, Caslon, in 1912. [1] Meynell’s desire to raise the quality of printing led to the graphic designer E. McKnight Kauffer being appointed Director of Pictorial and Poster Advertising in the early 1920s. [2] The Westminster Press was one of a few notable small printing presses of the period, who were experimenting with and disseminating new typefaces and book layouts; these presses positioned themselves in the legacy of the Arts and Crafts movement, where high-quality, well-designed, hand-crafted objects were highly praised.
