Posters & Infographics With Real Text: Crisp Chinese Headlines, Clean Layout

The latest image models (e.g. Nano Banana Pro, Jimeng) are markedly better at rendering text inside images and can fairly reliably produce posters, infographics, and e-commerce hero images with real headlines. But for accurate type and tidy layout, 'make a poster' won't cut it — treat the copy and layout as hard constraints: 1) Lock the exact text in quotes, word for word (headline/subhead/button), and state the language; 2) Specify the layout (top/middle/bottom structure, where text and whitespace go, alignment); 3) Give style and palette (flat/editorial, primary color, font weight); 4) Give the aspect ratio. Template: "A [purpose] poster in Simplified Chinese. Headline: '…'; subhead: '…'. Layout: headline centered near the top, three icon+caption columns below, a line of fine print '…' in the bottom margin. Style: […], primary color […], ratio 3:4. Text must be crisp and spelled exactly right." If a few characters still come out wrong, inpaint just the text area rather than re-rolling the whole image.

新一代图像模型（如 Nano Banana Pro、即梦）在「图里写字」上明显变强，已经能比较稳地出带标题的海报、信息图、电商主图。但要字准、版面齐，不能只说「做张海报」。诀窍是把文案和版式当成硬约束写清楚：1）用引号锁定要出现的文字，逐字给（标题/副标题/按钮），并说明语言是简体中文；2）指定版式（上中下结构、文字区与留白位置、对齐方式）；3）给风格与配色（扁平/杂志风、主色、字重）；4）给画幅比例。模板：「一张[用途]海报，简体中文。主标题：『……』；副标题：『……』。版式：标题居中靠上，下方三栏图标+短句，底部留白放一行小字『……』。风格：[…]，主色[…]，比例 3:4。文字必须清晰、拼写完全正确。」出图后若个别字仍错，用局部重绘只修文字区域，别整张重抽。
