GPT Image 2 图片内文字:让标题、标签和 UI 更清晰的提示词模板

2026/04/24

如果你总觉得模型“不会拼字”,很多时候问题其实不是拼写本身,而是你没有把 exact strings、placement 和 contrast 讲清楚。

这篇文章把 GPT Image 2 text in image 的常见工作流拆成一套可直接复制的模板:海报 headline、缩略图文字、商品角标、菜单板、UI mockup,以及一组专门用来修复文字问题的微模板。核心思路只有一句话:先把版式说清楚,再谈风格

先判断问题到底出在哪

在你继续 reroll 之前,先用这三种方式判断:

  • 文字内容不对:把文案缩短,改成 exact strings,并明确写 verbatim
  • 文字看不清:提高对比度,给文字留出干净背景,必要时加 stroke
  • 文字位置乱跑:给 text-safe zone、margin、alignment 和固定锚点

这三类,其实就是大多数 GPT Image 2 text in image 问题的根源。

图片内文字通用清单

只要画面里有字,建议默认把这些约束写进去:

  • exact strings in quotes
  • hierarchy:headline / subhead / CTA
  • placement anchors
  • clean text-safe zone
  • safe margins
  • contrast rule
  • no extra text anywhere
  • 一次只改一个变量

可读文字的提示词结构

要让 GPT Image 2 text in image 更稳定,prompt 里至少要有这七层:

  1. 资产类型与平台
  2. 逐字文案
  3. 层级关系
  4. 位置与安全区
  5. 背景与对比度规则
  6. 字体与字重约束
  7. 硬约束:不要额外文字、日期、符号和水印

适合短文案的 exact strings 示例

如果你要做清晰的图片内文字,优先使用短句:

  • "SPRING SALE"
  • "NEW"
  • "LIMITED DROP"
  • "TRY IT FREE"
  • "SHOP NOW"

文案越短,GPT Image 2 text in image 的可读性通常越高。

微模板库:先修小问题

下面这些微模板适合直接插到任意大模板里,用来补 exact strings、安全区、边距、对比度和背景整理。

Micro template — gpt-image-2 text in image: exact strings only
Use the following text verbatim and do not add any other words. No extra text anywhere.
Micro template — gpt-image-2 text in image: text-safe zone
Create a clean text-safe zone at {PLACEMENT} occupying {PERCENT}% of the canvas. Keep it free of patterns.
Micro template — gpt-image-2 text in image: safe margins
Keep {PERCENT}% safe margins on all sides. Do not place text near the edges.
Micro template — gpt-image-2 text in image: contrast rule
Ensure high contrast between text and background. If background is dark, text must be light (and vice versa).
Micro template — gpt-image-2 text in image: outline stroke
Add a subtle outline/stroke to the text to preserve readability at thumbnail size.
Micro template — gpt-image-2 text in image: no decorative fonts
Use a clean bold sans font for the headline. Avoid decorative fonts.
Micro template — gpt-image-2 text in image: two lines max
Limit headline to 2 lines maximum. Keep words short. Increase font size.
Micro template — gpt-image-2 text in image: simplify copy
Rewrite the headline to 3–5 words and the subhead to under 8 words while preserving meaning.
Micro template — gpt-image-2 text in image: lock layout anchors
Keep the text block position fixed across variants. Do not move it. Keep margins identical.
Micro template — gpt-image-2 text in image: one-variable variants
Generate 3 variants changing ONLY {VARIABLE}. Keep layout, margins, and text placement identical.
Micro template — gpt-image-2 text in image: remove background noise
Simplify the background behind text. Use a subtle blur or a solid backing shape behind the text.
Micro template — gpt-image-2 text in image: forbid random numbers
Do not add random numbers, dates, hashtags, or symbols unless explicitly provided in the exact strings.

可直接复制的大模板

模板 1:海报 headline + CTA

适合活动图、品牌海报或短周期促销图。重点是先把 headline 区和 CTA 区固定住。

模板 4:菜单板(文字少而整齐)

菜单板最容易因为信息量过多而崩掉,所以这类图必须强制控制条目数和版式。

模板 5:UI mockup 主标题 + 按钮

如果你需要一张像 SaaS 截图的营销图,这个模板会优先约束 grid、左文右图和按钮可读性。

gpt-image-2 text in image template — UI mockup hero
Create a clean SaaS landing UI mockup screenshot with readable hero text.

一套更稳的工作流

如果你的目标不是“一张看起来不错的图”,而是一批可复用的素材,流程会比单条 prompt 更重要:

  1. 先用 /text-to-image/gpt-image-2 出基线图
  2. 布局接近时,切到 /image-to-image/gpt-image-2 调整文案和间距
  3. 每轮只改一个变量,例如 headline、颜色或 placement
  4. 把好用的 exact strings、safe margins 和 badge 规则沉淀成团队模板

常见问题

为什么长文案更容易失败?

因为字一长,字号就会变小,层级和间距也更容易乱。先缩短 headline,再把 hierarchy 和 safe zone 说清楚。

图片里为什么会多出随机文字?

通常是因为你没有明确写 no extra text,也没有限制背景和文本区域。加上 exact strings + no extra text,效果会稳很多。

什么时候该放弃继续 reroll,转去编辑?

当画面的构图已经接近可用,只差文字位置、背景清理或局部修正时,就别再整张重抽了,直接去 /image-to-image/gpt-image-2
