RISO孔版印刷风艺术海报设计

vertical high-end art posters, each uploaded photo is a separate artwork, one image per poster, no multiple images stitched together. The top and bottom of the image are strictly 1:1, each occupying 50%. The upper half retains the original photo, preserving the subject's identity, facial features, structure, posture, proportion, realistic texture, natural lighting, and original color atmosphere, with only slight high-end color correction to achieve the quality of an independent magazine, art photography collection, or exhibition catalog. The environment can be naturally extended to fit the frame, but stretching, distortion, alteration of the subject, or generation of incorrect structures are prohibited. The lower half extracts the most recognizable subject outline, posture, clothing, architectural structure, animal features, or scene relationships from the upper photo and reconstructs them in a "RISO stencil printing + hand-drawn line art + editorial illustration" style. It does not realistically reproduce the image, only retaining the most recognizable visual elements. The lines are simple and free, allowing slight jitter, broken lines, misalignment, and incomplete closures to reflect the authentic hand-drawn and stencil-making marks. Use 2-4 spot colors, extracted and rearranged from the above photos, such as coral orange, peach pink, vintage blue, ultramarine, sage green, cream yellow, soft purple, black, and off-white. Slight misregistration, halftone dot overlap, uneven ink distribution, and transparent overlap are permissible, while avoiding complex gradients and a smooth vector feel. The background should retain the warm texture of paper grain, fine fibers, printing dots, and slight ink smudges, resembling independent publications, art books, and hand-printed posters. The lower half employs a "small subject + large white space" composition, which can be off-center, aligned with the edges, or partially cropped, emphasizing positive and negative space, a sense of breathing, and visual rhythm. Complex backgrounds should be removed, retaining only essential elements, such as arrows, stars, numbers, dates, small flowers, coordinates, or hand-drawn symbols. Text should be minimally incorporated, including short titles, dates, numbers, or footnotes. The font should be small, light, and restrained, referencing art magazine and exhibition poster layouts, avoiding excessive commercial headlines. Overall feel: sophisticated, artistic, warm, youthful, relaxed, modern, and collectible. Avoid realistic redrawing, anime, chibi, 3D, AI plastic feel, neon colors, complex gradients, commercial templates, full-page stacking, excessive text, cluttered backgrounds, and distorted subject.
