Zoé Pignolet’s authenticity certificates

French embroidery artist Zoé Pignolet commissioned type designer Tanguy Vanlaeys to create certificates of authenticity for her works. Included with each piece, these certificates serve to identify the artwork and confirm its status as a unique creation, personally signed by the artist. What sets these certificates apart is their production method: they are drawn with a pen plotter, a specialized machine that, unlike traditional inkjet or laser printers, uses one or more pens to render smooth, continuous lines. Known for his expertise in designing typefaces for such machines, Vanlaeys chose his Milling SL (SL for single line) font in its Simplex version – available through 205TF – for this project. This typeface is notable for its single-line construction, specifically optimized for CNC machines, including pen plotters, milling machines, and laser cutters.
