Text Rendering Tips

For best text results with the Pro model:

1. Use quotes around exact text: "Title: \"Hello World!\""
2. Specify font details: color, style, size, position
3. Disable prompt_extend: Set prompt_extend: false for precise control
4. Use negative prompts: "blurry text, distorted text, low quality"

Example prompt structure:

Poster with the title "GRAND OPENING" in large red serif font at the top center.
Below, the date "March 15, 2024" in smaller black text.
Background: elegant gold and white gradient.
Style: professional, clean, modern.

Recommended Negative Prompt

{
  "negative_prompt": "low resolution, low quality, deformed limbs, deformed fingers, oversaturated, waxy, no facial details, overly smooth, AI-like, chaotic composition, blurry text, distorted text"
}
