How to Write Text in AI Images with Flux.1 Schnell & Dev

By PixelPrompt Editorial4 min readUpdated September 2026

One of the biggest historic weaknesses of AI image generators like Stable Diffusion and early Midjourney versions was text rendering. Faces were gorgeous, but any attempt to render a shop sign or neon text produced unreadable gibberish. Flux.1, created by the original founders of Stable Diffusion at Black Forest Labs, solved this problem completely.

The Secret: Using Double Quotes

In Flux.1, always wrap the exact words you want rendered inside double quotation marks ("LIKE THIS"). Flux's transformer-based text encoder prioritizes quoted strings for letter-by-letter rendering.

T-Shirt & Apparel Typography

If you are designing t-shirt mockups or merchandise with AI, specify the font vibe (e.g. bold vintage serif, minimalist sans-serif) right alongside the text string:
