“工作原理 部件清单 用户反馈” es un efecto de texto Máquina de Escribir creado con FontVibe IA. Tipos slab monoespaciados golpeados sobre papel crema, con densidad de tinta irregular, textura de cinta, leve desalineación y suaves fibras de papel.

Monospaced typewriter letterforms with authentic mechanical key-strike impressions. Uneven ink distribution — some strokes darker, some lighter, ink thicker at stroke terminals. Aged cream bond paper surface with subtle fiber texture. Vintage Underwood No.5 aesthetic. Warm sepia-tinted black ink. Slightly irregular baseline alignment, individual letter spacing imperfections. Visible ribbon texture on letterforms. Clean vintage typewriter quality. Portrait 3:4. Render the exact Chinese text in three vertically stacked lines: “工作原理” at the top, “部件清单” centered beneath it, and “用户反馈” at the bottom. The three lines form a disciplined technical-document hierarchy, evenly spaced with generous cream-paper negative space around them. Each character carries authentic mechanical typewriter key-strike impressions: warm sepia-black ink with subtly broken coverage, darker deposits at dense terminals, faintly lighter areas through the centers, and delicate ribbon grain visible inside the marks. Allow slight baseline irregularity and tiny spacing inconsistencies between characters, as if produced one strike at a time by an aging machine. Background is a single sheet of aged cream bond paper, matte and softly yellowed, with restrained natural fibers, minute specks, and barely visible pressure impressions around the text. Gentle side light reveals the paper grain and shallow ink indentation without creating decorative shadows. Keep the composition stark, archival, and practical: an old technical manual page with no borders, illustrations, stamps, ornaments, or additional writing.
