Arbotek has the original skeleton that the author used for the development of his typeface Arboria, a real ‘architect typography’, with a basic and radical approach to pure geometric forms. The three basic styles - Thin, Light and Light Rounded - try to approach the cartographic technique annotations and their output on plotters. The voluptuous style, Ultra, keeps the same structure of the Light versions, but develops as a historic Art Decó variant of this 20s and 30s graphic style.
