Hangul 訓民正音 is the carbon-black voice of the Hunminjeongeum Haerye — the 1446 woodblock treatise in which King Sejong gave Korea a writing system built from the shapes of the speaking mouth and the 天地人 cosmology. It reads as a Joseon xylograph: vertical right-to-left columns ruled by black frames, set on aged mulberry-bark hanji the color of steeped tea.
This system honours that printed page. Tannin-brown paper carries carbon ink; vermilion appears only as rubrication. Letterforms stay geometric and featural, never softened. The grid is law, the column is the unit, and every accent earns its place.
Hangul 訓民正音 取自 1446 年的《训民正音·解例本》——朝鲜世宗大王颁布的木刻典籍，韩文字母由发音器官的形状与「天地人」三才衍生而来。它呈现为一页地道的朝鲜雕版印刷：黑框栏线划分出竖排、从右向左的文字列，承载在染了单宁、色如浓茶的桑皮韩纸之上。
这套设计系统忠实于那一页雕版。单宁褐纸面承载碳黑墨色，朱红只作句读与圈点之用。字形保持几何化的「象形」构造，绝不圆滑软化。栏格即法度，文字列即单元，每一处点缀都须各得其所。
