Very few letter types with the context of grunge style fonts offer hierarchies to differentiate words in sentences or paragraphs. With Navaja I developed a font family that meets this need. This family is useful to organize the information into a hierarchy with an eroded look. Its central idea mixes grotesque, geometric and humanistic letter conventions. This way, Navaja is a grunge-sans with dense proportions to make graphic design with eroded character. Its main purpose appeared when one of my customers asked me for a t-shirt design for a fan club of an important football player. For this reason its starting point were stained and muddy letters characterizing the toughness and coldness of the sport. Over time their glyphs began to imitate the robustness of "wood type & Tuscan Type" widely used in posters in the late nineteenth century. Its purpose was strengthened in a family with 6 members that when mixed they produce mind catching contrast levels ideal for designing T-shirts, stickers, flyers, brochures, posters, billboards, cinema or TV. Therefore its variants are short up and down height X combined with different widths that by working together produce information that radiates outstanding apparently destroyed controlled violence. Navaja Dingbats consists of 52 illustrations useful for frames and textures. In that vein, the origin of each member comes from skeletons of Roman and Italic calligraphy. The low amount of contrast between thick and thin lines matching the contours apparently gnawed but strictly regulated by optical adjustments equating the sum between full and empty areas. Factors such as finishes, shapes and counter internal and external forms are meticulously planned although its scruffy look which strategic arrangements are offset to provide color typographical homogeneous. And in conclusion, I have plans to continue expanding the family with more complete versions in the future.
