高级复古丝网印刷旅行海报插图提示词

Create a premium 4:5 vertical retro screen-print poster illustration centered on [SUBJECT / LANDMARK / CITY / ERA]. The composition should feel like a refined vintage travel or cultural print, while remaining adaptable to any location, historical period, landmark, or subject.

TYPOGRAPHY: Place the primary title "[MAIN TITLE]" in a bold, condensed uppercase sans-serif, positioned within a balanced area of negative space. Add a smaller supporting line "[SECONDARY HEADLINE / LOCATION / DATE]" beneath it. Maintain strong typographic hierarchy, restrained spacing, and an authentic archival-poster character.

MAIN SUBJECT: Feature [PRIMARY SUBJECT] as the dominant visual element, positioned within the lower or side third of the composition. Use a distinctive pose, silhouette, or profile that communicates the character of the subject. Include carefully rendered defining details, natural contours, expressive features, clothing or architectural details, and subtle highlights without making the artwork photorealistic.

GEOMETRIC ANCHOR: Introduce one bold, simple geometric shape behind or around the main subject to create visual separation and establish a strong graphic focal point.

BACKGROUND: Construct the environment as several flat, layered graphic planes rather than a conventional realistic scene. Use recognizable elements associated with [LOCATION / SUBJECT] — distant silhouettes, architectural forms, structural details, vegetation, terrain, atmospheric elements, or cultural motifs. Avoid a strong vanishing point. Build depth through overlapping shapes, scale, linework, and tonal density. Render clouds, smoke, mist, foliage, or atmospheric details as controlled stippled clusters where appropriate.

RENDERING STYLE: Authentic vintage screen-print / silkscreen poster aesthetic. Create all tonal modeling exclusively through stippling, halftone patterns, and varying dot density — concentrated dots for shadows and sparse dots for highlights. No smooth gradients, airbrushing, photorealistic shading, or digital 3D rendering. Use crisp contour lines with consistent visual weight, subtle riso-style registration shifts, imperfect ink edges, natural paper grain, and faint woven-print texture. The result should feel physically printed rather than digitally rendered.

COLOR SYSTEM: Use exactly four carefully selected high-contrast colors appropriate to the subject: [COLOR 1], [COLOR 2], [COLOR 3], [COLOR 4]. Do not introduce additional hues. Generate intermediate tonal values exclusively through stipple density, halftone overlap, and ink coverage, never by adding new colors.

COMPOSITION: Strong editorial balance, clear focal hierarchy, generous negative space, layered depth, bold silhouette design, authentic vintage graphic-design proportions, and carefully controlled visual density. Keep the artwork sophisticated, collectible, and suitable for a premium travel or cultural poster.

OUTPUT: 4:5 vertical aspect ratio, edge-to-edge poster composition, high detail, crisp print-ready appearance, cohesive screen-print texture, no modern photographic elements.

创建一个以 [主题 / 地标 / 城市 / 时代] 为中心的高级 4:5 垂直复古丝网印刷海报插图。构图应具有精致的复古旅行或文化印刷品感，同时保持对任何地点、历史时期、地标或主题的适应性。

排版：将主标题“[MAIN TITLE]”置于粗体、紧凑的大写无衬线字体中，并位于负空间的平衡区域内。在其下方添加较小的辅助行“[SECONDARY HEADLINE / LOCATION / DATE]”。保持强大的排版层级、克制的间距和真实的档案海报特征。

主体：将 [PRIMARY SUBJECT] 作为主要视觉元素，放置在构图的下三分之一或侧三分之一处。使用独特的姿态、剪影或轮廓来传达主体的特征。包括精心绘制的定义细节、自然轮廓、富有表现力的特征、服装或建筑细节以及微妙的高光，而不要让艺术品呈现出写实主义。

几何锚点：在主体后面或周围引入一个大胆、简单的几何形状，以创造视觉分离并建立强大的图形焦点。

背景：将环境构建为几个扁平、分层的图形平面，而不是传统的写实场景。使用与 [LOCATION / SUBJECT] 相关的可识别元素——远处剪影、建筑形式、结构细节、植被、地形、大气元素或文化图案。避免强烈的透视灭点。通过重叠形状、比例、线条和色调密度构建深度。在适当的情况下，将云、烟、雾、树叶或大气细节渲染为受控的点画集群。

渲染风格：真实的复古丝网印刷 / 丝印海报美学。完全通过点画、半色调图案和变化的网点密度来创建所有色调建模——浓密的点表示阴影，稀疏的点表示高光。没有平滑的渐变、喷枪、写实阴影或数字 3D 渲染。使用具有一致视觉重量的清晰轮廓线、微妙的 Riso 风格套印偏移、不完美的墨水边缘、天然纸纹和隐约的编织印刷纹理。结果应该感觉像是物理印刷的，而不是数字渲染的。

色彩系统：使用四个精心挑选的、适合主题的高对比度颜色：[COLOR 1]、[COLOR 2]、[COLOR 3]、[COLOR 4]。不要引入额外的色相。仅通过点画密度、半色调重叠和油墨覆盖产生中间色调值，绝不通过添加新颜色。

构图：强大的编辑平衡、清晰的焦点层次、丰富的负空间、分层的深度、大胆的剪影设计、真实的复古图形设计比例以及精心控制的视觉密度。保持作品的精致、具收藏价值，并适用于高级旅行或文化海报。

输出：4:5 垂直纵横比，边到边的海报构图，高细节，清晰的打印就绪外观，连贯的丝网印刷纹理，没有现代摄影元素。
