🍌 TUTORIAL — How to Reduce Text Errors in Banana (Without Promising the Impossible)

⚠️ 0. An Honest Warning Before Starting

Banana, like all AI image generators (Imagen, Firefly, Leonardo, etc.), wasn’t fundamentally designed to write perfectly legible text. It draws letters instead of “writing” them.

👉 This means that no method, however precise, guarantees 100% accurate text: you can get an excellent result on one image, and a disaster on the next… with the same prompt.

💡 The purpose of this guide is therefore not to promise perfection, but to help you drastically reduce errors — mistakes, missing accents, merged letters, etc. With the right approach, you can achieve 80 to 90% stable success.

🧭 1. Why Banana Often Writes Text Incorrectly

  • French accents are misinterpreted (é, à, ç, etc.)
  • Letters merge or warp
  • Certain words trigger visual errors (“besoin”, “école”, “société”)
  • Text can be blurry, partially hidden, or poorly centered
  • And Banana tends to translate or simplify French

➡️ This guide shows you how to guide the model to get more reliable results.

⚙️ 2. The 5 Golden Rules to Limit Errors

🧩 Rule 💬 Explanation
1. Describe the scene first, then the text. The model must “see” the context before adding text.
2. Specify that the text is printed, not handwritten. This reduces distortions and decorative letters.
3. Mention the language and typographic style. Example: text in clear French, perfectly written.
4. Use a square format (1:1). It’s the most stable for text positioning.
5. Keep text short. Less than 25 characters = better chance of sharp letters.

🧱 3. Ideal Structure for a Banana Prompt

Create an image representing [the subject]. The scene should evoke [the emotion or situation]. Add at the top (or bottom) of the image text in clear French, white with black outline, perfectly written and centered: “[your exact text]” The text should be integrated into the image (as if printed), sharp and legible. Style: [realistic, humorous, inspiring, etc.]. Format: square 1:1.

💡 Universal Tip: Problem Words

Certain words cause recurring errors (fusion, replacement, missing accent). Examples: besoin, école, société, succès, énergie. In this case, add to your prompt:

“The word [concerned word] must be perfectly written and legible in the image.”

Or temporarily generate with a neutral version:

“beso1n” → to correct later in Canva or Photoshop.

✏️ 4. Optimizing for Text — From Error to Mastery

1. Limit Text Length

Keep your text to 20-25 characters maximum. Beyond that, letters stick together or accents jump. If your sentence is longer: split it into two lines.

2. Use an Iterative Process

  1. Generate the image.
  2. Check: accents, fusion, sharpness.
  3. If needed, relaunch with a corrective command:

    “Fix the caption so that every letter is clear and crisp.” or “Correct the spelling of the text as clean typographic French.” Each pass refines the result.

3. Create a Dedicated Text Zone

“Leave an empty and clean space at the top of the image for the caption.”

This forces Banana to reserve a clear area, ideal for text. Use white with black outline to maximize legibility.

4. Always Specify Language and Writing Type

“Text in French, perfectly written, typographic, not handwritten.”

This sentence reduces hallucinations and random artistic fonts.

🚫 5. Problem Words (and Their Solutions)

🧩 Problematic Word 💥 Typical Error 💡 Simple Solution
besoin merged letters “beso1n” then correct
préféré replaced accents “prefere” then correct
école becomes “cole” specify “the word école must be legible”
société “sociey” write “societe” temporarily
énergie “enargy” write “energie”
succès “succes” or “succer” 😅 write without accent
cœur “coer” or “cour” write “coeur”
réalité “realty” write “realite”
créatif “cratif” write “creatif”

🎨 6. Recommended Banana Settings

Parameter Recommended Value Why
Format 1:1 (1080×1080) perfect meme format
Style Realistic or Cinematic sharp letters
Sharpness 0.7 – 0.8 more typographic sharpness
Text emphasis ✅ Enabled prioritizes text
Seed Fixed (e.g. 42) consistency between generations

✅ 7. Post-Generation Checklist

Before exporting your image, check these points:

  • Text is complete and legible
  • No accent has disappeared
  • Letters don’t touch
  • Sensitive words (besoin, école, etc.) are correct
  • Text/background contrast is good
  • Text is well centered
  • Square format (1080×1080) respected

🧾 8. Example Final Prompt to Copy-Paste

Create a humorous meme image on the theme of everyday life. Show a person in a funny and relatable situation. At the top of the image, write text in clear French, white with black outline, well centered and legible: “[Your text here]” The text should be integrated into the photo, typographic and not handwritten. Text in French, perfectly spelled. The word [sensitive word] must be perfectly written and legible in the image. Style: realistic, light atmosphere, square 1:1 format.

🧩 9. In Summary

No method allows you to get perfect text with every generation. But by combining these techniques, you:

  • reduce errors by 60 to 90%,
  • improve visual consistency,
  • and save retouching time.

🎯 That’s exactly the goal of this guide: make Banana a reliable tool for producing images with usable text.
