“黒沢清”是使用 FontVibe AI 创作的日本水墨毛笔文字效果。把日本书道的水墨毛笔笔法用到拉丁字母上。浓黑的墨汁配上地道的毛笔笔势、单向可控的运笔，还有和纸的质感。做日料店品牌、纹身设计、动漫、武道和文化类项目都特别合适。

Create a restrained portrait calligraphy artwork on warm cream-white washi paper, with the exact Japanese text "黒沢清" as the only lettering. Arrange the three characters vertically, one character per line, read top to bottom, centered on the page. Use classical Japanese shodo brush calligraphy: upright, harmonious forms with bold 5:1 thick-to-thin strokes, controlled loaded-brush entries, deliberate energetic middles, and precise harai exits tapering to fine points or subtle upward hooks. Each stroke is executed once with commitment. Render the marks in matte sumi ink, near-black at stroke centers, transitioning naturally to charcoal gray and faint dry-brush texture only at outer edges. The ink is absorbed into the paper, with soft-edged borders and no gloss. Preserve the washi's subtle visible fiber structure. Soft diffuse north-facing studio light, even and shadowless. Leave broad, carefully balanced empty space around the vertical text; no props, ornament, borders, extra marks, or additional text. Ensure all three Japanese characters are accurate, clearly formed, and legible.
