How style prompts can make AI-generated posters more distinctive

Summary

The author argues that AI-generated event posters often feel repetitive because they rely on a familiar visual template, and tests whether more specific style directions can help. An initial ChatGPT poster for an invented spring fayre still looked too much like the conventional craft-fair aesthetic, even after the author requested a clean, bright layout and rejected pastel or painterly imagery. Asking for a completely different design aesthetic produced a Bauhaus-influenced geometric poster that the author found more distinctive. ChatGPT then suggested a range of styles, and the author tried several, including letterpress, Japanese minimalism, Memphis design, punk fanzine, and drum-and-bass flyer styles. During these iterations, an extra tagline appeared and carried into later posters because it had become part of the conversation context; the author notes that starting from scratch with the desired style can avoid such accumulated details. The posters still looked AI-generated to the author, but they were varied and not ugly. The article also notes that Claude and Gemini can produce editable HTML, PNG, and PDF outputs with real text and layers, rather than only flattened images. The author says the experiment inspired a catalogue of 100 poster styles with prompts and example images.
