A sturdy serif with pronounced, bracketed serifs and a dark, even color on the page. Strokes show moderate modulation, with thickened verticals and slightly lighter joins, producing a confident texture without feeling overly delicate. Terminals are often softly rounded and the serifs have a subtly cupped, ink-trap-like feel in tight interior corners, helping preserve clarity at heavier weights. The letterforms are broadly proportioned with generous bowls and relatively open counters, and the lining figures are weighty and highly legible with strong curves and clear differentiation.
Works well for editorial typography, book pages, and dense text that benefits from a firm, dark typographic color. It also suits headlines and subheads where a classic serif voice is desired, plus formal materials like invitations or certificates and traditional packaging that needs a trustworthy, established feel.
The overall tone is traditional and institutional, evoking printed book typography and established editorial voices. Its heavy, steady rhythm reads as confident and dependable, with a hint of old-style warmth from the rounded details and bracketed serifs.
The design appears intended as a conventional serif with a stronger-than-usual presence, balancing classic proportions with practical, readability-oriented details that keep counters open and joins clean at heavier stroke weights.
In the sample text, the face maintains a consistent, bold text color and holds together well across mixed case, with strong capitals and a robust lowercase that keeps interior spaces from collapsing. The numerals match the letters in heft and presence, making them suitable for text settings where figures need to be noticed without looking decorative.
