A sturdy slab-serif with compact, blocky proportions and emphatic, mostly square-ended terminals. Strokes are even and dark, with short, firm serifs that read as slightly softened/bracketed rather than razor-sharp, giving the forms a practical, engineered feel. The lowercase shows a two-storey “a,” a single-storey “g,” and a robust, upright “r,” while the capitals maintain a consistent, somewhat condensed rhythm with confident horizontals and squared counters. Numerals are strong and pragmatic, with a clear, open “4,” a rounded “8,” and a simple “1” that stays distinct in text.
Well-suited to long-form reading in print or on screen where a solid serif presence helps guide the eye. It also works effectively for headings, pull quotes, and utilitarian layouts such as reports, manuals, academic materials, and forms where a dependable, traditional voice is desired.
The overall tone is functional and no-nonsense, evoking printed matter, office documents, and classic editorial typography. It feels reliable and workmanlike, with a subtle vintage/typewriter association rather than a delicate or luxurious mood.
The design appears intended to deliver a durable slab-serif voice with strong legibility and an understated, practical personality. Its restrained detailing and firm terminals suggest a focus on dependable text setting with a hint of vintage document character.
In the text sample the dense color and firm serifs produce a clear, steady reading line and a slightly mechanical texture. The design favors clarity and stability over calligraphic nuance, with terminals and joins that stay crisp at display sizes.
