Text Prompting

Positive Prompt : (the word "Fuck" {on paper|in calligraphy|in the best quality}),[colorful] [street chalk]

Negative Prompt : (fibbinoci fractal, repetitive patterns)

Simple Text Syntax

To generate images with text in them, it's important to start with the text you want to appear in the image. For example: the word "fuck"

  • The word must be enclosed in " " and should not have a space.
  • The word will still be read as a term, ie the word 'fire' will cause flames in the image.

Tips for text:

  • Keep the prompt simple.
  • Test terms and balance them appropriately.
  • Compose the prompt with the text as the main subject.

Final Words

SDXL is a SFW model capable of a wide array of image styles, but it's worth noting that SDXL struggles with accurately rendering hands and may delve into excessive detail, which users will have to manage using the negative prompt. Additionally, challenges with skin texture may arise due to the SDXL refiner, which autocorrects the final image. Despite these drawbacks, SDXL increased resolution capability, and ease of multilpe character creation sets it apart.
