LL Plot
Lineto · Cornel Windlin, Pablo Desportes, Luca Pellegrini · 2022

A typeface reverse-engineered from an obscure default plotter font discovered on a pen-plotter at Schauspielhaus Zürich, refined and published two decades after its initial use.
About
Originally extracted from the in-house plotter at Schauspielhaus Zürich by Cornel Windlin around 2000, the source was a primitive single-stroke font left over from MS Windows-era pen-plotter software. Windlin used it across a poster campaign and season book before the files sat dormant on backup cartridges for twenty years, when Pablo Desportes rediscovered them and led a redevelopment with Luca Pellegrini, expanding the glyph set and adding Cyrillic. The result is two weights with condensed proportions, carrying the irregular logic of its industrial origins while meeting contemporary technical standards.
Classification
Derived from a primitive single-stroke default font pre-installed on an industrial pen-plotter, LL Plot has an irregular, technically-sourced letterform character that places it in the display category with a subcategory best described as plotter or technical vernacular.
