“10号” es un efecto de texto Deportes creado con FontVibe IA. Mayúsculas cromadas gruesas y condensadas con grano de serigrafía, luz de contorno roja y azul y la silueta de un atleta atravesando líneas de velocidad detrás.

Create a vertical 3:4 professional football jersey back-number graphic, intended for heat-transfer screen print on a deep near-black technical knit shirt panel. Render exactly one text string: “10号”. No other words, no logos, no badges, no athlete, no watermark. The lettering fills 76% of canvas height and 72% of canvas width, centered with generous clear fabric margin. Set “10号” as one aligned horizontal unit: the 1, 0, and Chinese character 号 share a single cap height. Build ultra-condensed, extremely heavy vertical-impact sports lettering; each character is at least 3:1 tall-to-wide, with tight tracking, flat-cut terminals, minimal counters, and squared interior corners. The character 号 must be custom-drawn to match the condensed numeral weight and compressed proportions. Letters are opaque warm white screen-print ink sitting on top of the textile, not luminous and not metallic. Add fine halftone grain across the ink face, microscopic knit interruption, and restrained 1–2 pixel ink edge bleed. A hard upper-left sidelight creates a narrow bright rim along left-facing outer edges and slim vertical specular strips on the narrow faces; deep charcoal shadow falls on the opposite right edges. Behind the type, use very faint pale-gray speed lines radiating outward from the center, stopping before they interfere with legibility. The background is deep black athletic jersey fabric with subtle woven rib texture and a quiet falloff toward the edges. Crisp front-facing print mockup, high contrast, clean production-ready silhouette, no glow, no gradients inside the ink, no extra decoration.
