MuirMcNeil ThreeSix Mono is a monospaced optical / geometric type system in four weights.
In ThreeSix a systematic progression of optical and structural interventions is used to generate a set of geometric typefaces which are highly distinctive at large sizes but which can also be read in bodies of extended text with comparative ease. In ThreeSix Mono, small spaces have been located at stroke junctions within letterforms, separating them into modular segments. The resulting stencil effect is easily visible at large sizes but in extended bodies of smaller text it produces a relatively light, open and even overall appearance.
ThreeSix Mono works within strict geometric constraints. It is based on the same grid as the other typefaces in the ThreeSix range – 36 unit squares subdivided into nine units – and is constructed from simple vertical or horizontal segments terminated by circular arcs.
ThreeSix Mono has four weights: 036 Extra Light, 072 Regular, 108 Bold, 144 Black. The strokes of all four weights align on a central horizontal and vertical axis onto which weight is added in 18 unit increments. In this way, width, stroke, cap-height, x-height, ascent and descent are modulated in vertical and horizontal registration on a fixed grid.
The grid also determines consistent character and word spacing, with all side-bearings conforming to nine unit increments. As contour weights become bolder, the resulting decrease in side-bearing values tightens the overall fit of character sequences, visually emphasizing the increase in weight.
Because ThreeSix Mono contours and spaces map onto each other precisely, a wide range of visual options is available to designers in both spatial and time-based design. Using bitmap, vector or moving image design software, users can apply selected contours either in precise registration or in easily calibrated positional offsets.
