2. 打开即梦→「高级模式」→粘贴英文 prompt→画幅选 4∶5
3. 生成 6 张→选 2 张构图完整→放大 4K
4. PS 打开→用品牌标准字替换模糊文字（保持字号≥120 pt 过审）
5. 产品区若失真→额外拍白底图→AI 抠图→正片叠底融合
6. 加促销贴纸：红色条 720×120 px，置底，放「限时直降¥××」
7. 输出三件套：

• 主图 800×800 JPG ≤500 KB

六、常见问题 FAQ

Q1. AI 总把中文写成乱码？ A：先关「文字识别」，出图后用 PS 替换标准字，避免平台 OCR 误判。

Q2. 产品变形怎么办？ A：白底图单独拍→AI 抠图→在可灵里用「Image-to-Image」权重 0.4 融合，保留结构。

Q3. 品牌色跑偏？ A：生成后手动拉「色彩倾向」或 PS 里建「颜色查找」3DLUT 秒变标准色。
