现代极简半调网点自然风海报

Generate a clear, bright, design-oriented image centered around any subject: the scene uses a large area of clean, light-colored, airy background to support the subject, the subject does not appear in a complete realistic form, but is translated into several huge halftone dot outlines, parts enter from the edges and are cropped, forming light overlapping, displacement, and tension from negative space; a finer linear structure passes through the main body from below or the side, like the skeleton, path, or growth line of the subject, carrying direction and order; then add a small-scale derived symbol of the subject as a visual pause, creating breath between the large shapes and small dots. Colors are extracted from the subject's own material, seasonal feel, cultural semantics, and emotions, maintaining the relationship between a large area of high-brightness background color, clear main color dots, small area of structural color, and light accent colors, overall bright and light, clean and airy, with clear but not overly heavy saturation, textures only present fine paper and regular halftone dots, without creating a sense of aged, smoky, or muddy feeling. The information layer adopts a restrained layout rhythm: the main title can be in a large font size close to the center of gravity of the negative space, with loose letter spacing, forming a calm hierarchical contrast between Chinese and Western text or main and secondary information; auxiliary information is scattered in corners or edges in extremely small font sizes, like dates, serial numbers, and markings on printed matter, enhancing the sense of precision without stealing from the main form. The overall effect should be like a piece of modern art print, reading the enlarged halftone subject outlines and fresh negative space first, then the fine line structures, small symbols, and textual order.

围绕任意主题对象生成一张清透、明亮、带设计感的图像：画面以大面积干净浅色空气感底面承托主题，主题不以完整写实形态出现，而被转译成若干巨大的半调网点轮廓，局部从边缘进入并被裁切，形成轻盈的遮挡、错位和留白张力；一个更细的线性结构从下方或侧向穿过主形体，像主题的骨架、路径或生长线，承担方向和秩序；再加入一个小尺度的主题派生符号作为视觉停顿，使大形与小点之间产生呼吸。色彩从主题自身的材质、季节感、文化语义和情绪中提取，保留大面积高明度底色、清晰主色点阵、小面积结构色和轻巧强调色的关系，整体明亮轻快、干净通风，饱和度清楚但不过度厚重，纹理只呈现细腻纸面与规则网点，不制造陈旧、烟灰或浑浊感。信息层采用克制的版式节奏：主标题可大字号贴近留白重心，字距松弛，中文与西文或主副信息形成冷静的层级对照；辅助信息以极小字号分散在角落或边缘，像印刷品上的日期、编号与标记，增强精确感而不抢夺主形。整体效果应像一张现代艺术印刷物，先读到被放大的点阵主题轮廓和清爽留白，再读到细线结构、小符号与文字秩序。
