A sturdy slab serif with square, flat-ended serifs and terminals and a mostly monolinear stroke rhythm. The letterforms are compact and boxy, with rectangular bowls and counters that read cleanly at text sizes. Serifs are unbracketed and strongly horizontal, creating a pronounced baseline and cap-line presence. Details like the small, notched joins on some strokes and the overall squared-off geometry give the design a deliberate, engineered texture, while spacing stays even and utilitarian.
Works well for headlines and subheads where strong horizontals and slab weight can anchor a layout. It also suits posters, labels, and branding systems that want a straightforward, authoritative voice with a vintage-industrial edge. In longer passages it can read clearly, especially when used with comfortable leading to offset the dense, squared texture.
The font conveys an editorial, bookish tone—serious and slightly old-school, like academic headings or reference typography. Its crisp slabs and squared shapes lend an institutional authority, while the subtle notched detailing adds a faintly mechanical, industrial flavor rather than a soft or calligraphic one.
The design appears intended to deliver a robust slab-serif presence with crisp, square terminals and a controlled, print-oriented rhythm. Its geometry and notched detailing suggest a focus on clarity and impact, balancing readable text construction with a distinctive, engineered surface character.
Uppercase forms appear particularly emphatic, with wide horizontal serifs and simplified curves that often resolve into straight segments. Numerals and punctuation keep the same blocky, square-ended logic, supporting a consistent voice in mixed text and display settings.
