The letterforms and their partner extrudes were designed in tandem to provide visual harmony. Relationships have been built between the stem widths, extrude depths and the spacing in each weight to aid the rhythm and uniformity of the type. All terminals are at 90º or 45º with open counters and optically altered shapes.
All the extrude shapes have been adjusted for a consistent weight and to avoid obscuring the letterforms. Extrudes from diagonal strokes have been redrawn entirely and those within counters have been reduced. Transitions between flat extruded sides and adjoining curves have also been optically smoothed.
Finally, the distinctive chequered halftone was developed to produce smaller file sizes and aid rendering performance. Traditional halftone shading made with circles requires twelve data points to render each circle, whereas a square requires only four.
