中文提示词
创作一张精致的复古半色调海报艺术肖像，主角为 {argument name="subject name" default="PERSON_NAME"}。如果提供了参考照片，请使用该照片；否则，请根据所提供的人名创作肖像。最终图像必须仅为全出血插图，不得包含参考照片缩略图或嵌入式图像。 以醒目的 1960 年代至 70 年代丝网印刷 / 胶印平版印刷美学渲染主体，灵感源自复古政治海报、抗议艺术、复古杂志封面、演唱会海报和基于模版的图形插画。在将面部转化为高对比度墨水线条、交叉排线、点画法、半色调网点和雕刻风格阴影的同时，保留可辨认的面部比例和特征。避免照片级真实感、喷枪效果和平滑的渐变。 构图：严格采用向左的 90 度侧面轮廓，眼睛直视前方，下巴微抬，表情自信中性。在 4:5 或 3:4 的构图中垂直框选头部和上肩/胸部，主体约占画面的 70%–85%。在头部后方放置一个巨大的纯色太阳/光环圆圈，头发和肩膀略微打破其边缘。头发需高度细节化，呈现流动的发丝、方向性运动和图形化高光条纹。 背景：陈旧的奶油色、纸张或帆布纹理，带有不对称的几何色块、微妙的半色调图案、交叉排线、模拟印刷颗粒和轻微的丝网印刷瑕疵。保持设计精致且协调，避免杂乱。 色彩方向：自动选择一种由 2–4 种颜色组成的有限高对比度调色板。默认为暖奶油色 + 海报红 + 近黑色墨水，但也允许有品位的替代方案，例如深海军蓝 + 柔和红/橙色 + 奶油色、炭灰色 + 焦橙色 + 奶油色，或醒目的芥末黄/金色 + 黑色双色调。不得使用摄影色彩渐变。 排版：将主体姓名醒目地置于左上角，使用超粗体压缩无衬线字体或板状衬线字体，全大写，字间距紧凑，堆叠 1–2 行。在其下方使用较小的粗体压缩字体添加 2–4 个字的短语或描述，并使用海报的强调色。保持排版与构图融为一体，视觉平衡。 服装：使用简洁的现代或符合时代特征的服装，采用平涂色、可见的织物褶皱线条，并应用相同的半色调/雕刻处理。在适当的情况下保留参考照片中可辨认的配饰，但保持极简。 光影：在轮廓上使用单一的强定向光源，创造出醒目的图形阴影形状。通过交叉排线、点画法和半色调密度来构建阴影，而非使用渐变。 最终质量：清晰、高度细节化、可直接打印的海报插图，锐利的面部线条，真实的复古印刷纹理，强烈的图形层次感，可辨认的肖像，平衡的负空间，以及高端的编辑艺术指导。保持整体一致性。
原始提示词
Create a refined vintage halftone poster-art portrait of {argument name="subject name" default="PERSON_NAME"}. Use the uploaded reference photo when provided; otherwise, create the likeness from the named person. The final image must be a full-bleed illustration only, with no reference-photo thumbnail or inset image. Render the subject in a bold 1960s–70s screen-printed / offset-lithograph aesthetic, inspired by vintage political posters, protest art, retro magazine covers, concert posters, and stencil-based graphic illustration. Preserve recognizable facial proportions and identity while translating the face into high-contrast ink linework, cross-hatching, stippling, halftone dots, and engraved-style shading. Avoid photorealism, airbrushing, and smooth gradients. Composition: strict 90-degree side profile facing left, eyes looking forward, chin slightly lifted, confident neutral expression. Frame the head and upper shoulders/chest vertically in a 4:5 or 3:4 composition, with the subject occupying roughly 70–85% of the frame. Place a large solid-color sun/halo circle behind the head, with the hair and shoulders slightly breaking its edge. Make the hair highly detailed, with flowing individual strands, directional movement, and graphic highlight streaks. Background: aged cream, paper, or canvas texture with asymmetric geometric color blocks, subtle halftone patterns, crosshatching, analog print grain, and slight screen-print imperfections. Keep the design sophisticated and cohesive rather than cluttered. Color direction: automatically choose one limited, high-contrast palette of 2–4 colors. Default to warm aged cream + poster red + near-black ink, but allow tasteful alternatives such as deep navy + muted red/orange + cream, charcoal + burnt orange + cream, or a striking mustard/gold + black duotone. No photographic color gradients. Typography: place the subject's name prominently in the top-left, using an extra-bold condensed grotesque sans-serif or slab-serif in ALL CAPS, tightly kerned and stacked across 1–2 lines. Add a short 2–4 word epithet or descriptor beneath it in a smaller bold condensed typeface, using the poster's accent color. Keep typography integrated into the composition and visually balanced. Clothing: use simple modern or era-appropriate clothing with flat colors, visible fabric-fold linework, and the same halftone/engraving treatment. Preserve recognizable accessories from the reference when appropriate, but keep them minimal. Lighting: use one hard directional light source across the profile, creating bold graphic shadow shapes. Build shadows using cross-hatching, stippling, and halftone density rather than gradients. Final quality: crisp, highly detailed, print-ready poster illustration, sharp facial linework, authentic vintage print texture, strong graphic hierarchy, recognizable likeness, balanced negative space, and premium editorial-art direction.
