如果你總覺得模型「不會拼字」,很多時候問題其實不是拼寫本身,而是你沒有把 exact strings、placement 和 contrast 說清楚。
這篇文章把 GPT Image 2 text in image 的常見工作流拆成一套可直接複製的範本:海報 headline、縮圖文字、商品角標、菜單板、UI mockup,以及一組專門用來修復文字問題的微範本。核心思路只有一句話:先把版式講清楚,再談風格。

先判斷問題到底出在哪裡
在你繼續 reroll 之前,先用這三種方式判斷:
- 文字內容不對:把文案縮短,改成 exact strings,並明確寫 verbatim
- 文字看不清:提高對比度,給文字留出乾淨背景,必要時加 stroke
- 文字位置亂跑:給 text-safe zone、margin、alignment 與固定錨點
這三類,其實就是大多數 GPT Image 2 text in image 問題的根源。
圖片內文字通用清單
只要畫面裡有字,建議預設把這些約束寫進去:
- exact strings in quotes
- hierarchy:headline / subhead / CTA
- placement anchors
- clean text-safe zone
- safe margins
- contrast rule
- no extra text anywhere
- 一次只改一個變數
可讀文字的提示詞結構
要讓 GPT Image 2 text in image 更穩定,prompt 裡至少要有這七層:
- 資產類型與平台
- 逐字文案
- 層級關係
- 位置與安全區
- 背景與對比度規則
- 字體與字重約束
- 硬約束:不要額外文字、日期、符號與浮水印
適合短文案的 exact strings 範例
如果你要做清晰的圖片內文字,優先使用短句:
- "SPRING SALE"
- "NEW"
- "LIMITED DROP"
- "TRY IT FREE"
- "SHOP NOW"
文案越短,GPT Image 2 text in image 的可讀性通常越高。
微範本庫:先修小問題
下面這些微範本適合直接插進任何大模板裡,用來補 exact strings、安全區、邊距、對比度和背景整理。

如果你的目標不是「一張看起來不錯的圖」,而是一批可重複使用的素材,流程會比單條 prompt 更重要:
- 先用 /text-to-image/gpt-image-2 出基線圖
- 布局接近時,切到 /image-to-image/gpt-image-2 調整文案與間距
- 每輪只改一個變數,例如 headline、顏色或 placement
- 把好用的 exact strings、safe margins 與 badge 規則沉澱成團隊模板
常見問題
為什麼長文案更容易失敗?
因為字一長,字級就會變小,層級與間距也更容易亂。先縮短 headline,再把 hierarchy 和 safe zone 說清楚。
圖片裡為什麼會多出隨機文字?
通常是因為你沒有明確寫 no extra text,也沒有限制背景和文字區域。加上 exact strings + no extra text,效果會穩很多。
什麼時候該停止 reroll,改用編輯?
當畫面的構圖已經接近可用,只差文字位置、背景整理或局部修正時,就不要再整張重抽了,直接去 /image-to-image/gpt-image-2。
