A heavy slab serif with broad proportions, strong vertical stress, and compact internal counters that stay open through careful shaping. Serifs are thick and mostly square-ended, with subtle bracketing that softens joins without losing a blocky, engineered feel. Stroke contrast is noticeable in rounded forms and at joins, and several letters show small notches/ink-trap-like cut-ins that help preserve clarity at dense weights. The lowercase is sturdy and compact, with a single-storey a and g, a short-armed r, and a prominent, curved-shoulder n/m rhythm; figures are similarly robust and sit solidly on the baseline.
Best suited to attention-grabbing settings such as headlines, posters, mastheads, and bold branding where a sturdy slab presence is desired. It can also work for short editorial subheads or pull quotes, especially in print-oriented layouts where its dense color and strong baseline grip are an asset.
The overall tone is bold and pragmatic—more workwear than delicate—conveying authority and durability. It reads as classic and print-forward, with a slightly old-school, press-like personality that feels dependable and no-nonsense.
The design appears intended to deliver maximum impact and legibility at display sizes by combining thick, square-ended slabs with controlled contrast and counter-shaping that resists filling in. Its proportions and structural serifs suggest a goal of projecting strength and reliability while keeping letterforms recognizable in tightly set text.
The wide set and strong slabs create a steady horizontal rhythm, while tight apertures and deep joins add a dense, impactful texture. Round letters (O/Q/C) remain stable and well-supported by the heavy serifs, and the Q’s tail is assertive and easily distinguished at display sizes.
