高對比復古絲網印刷人像海報

Transform the original photo into a bold retro print-style poster while preserving the subject’s identity, pose, expression, clothing, and key objects. Simplify the original background into a clean solid or subtly textured color field. Use a limited two- or three-color palette with strong complementary tones, posterized shadows, high contrast, and slightly flattened colors. Add visible film grain, halftone dots, rough ink texture, and subtle screen-print imperfections across the image. Keep the subject recognizable and photographic, but give the entire image a vintage risograph / silkscreen print aesthetic with rich texture, graphic color separation, and a tactile analog feel. Clean composition, bold editorial poster design, retro print texture, stylish and visually striking.
