Produce an event poster that gets the date, time, and venue text right in Ideogram V3

Why this works

The single most common failure in AI-generated event posters isn't the headline — models handle a short bold event name reasonably well — it's the details block, where date, time, and venue tend to blur into one garbled line or get half-rendered as illegible fine print, because that block is functionally three separate short strings the model has to keep distinct rather than one phrase to stylize. This prompt addresses that directly by labeling each line explicitly (Line 1, Line 2, Line 3) inside the prompt itself rather than just concatenating them, which gives Ideogram a clearer structural cue to keep them as three separate visual lines instead of merging them into a single run-on sentence — a known weakness even in text-capable models when multiple short facts sit close together. The closing instruction not to add extra text matters because a mostly-empty bottom third is exactly where diffusion models like to add plausible-looking filler (a fake website URL, a made-up ticket price) to make the composition feel finished, and naming that boundary up front heads it off. Keeping the theme and background instructions separate from the text block, rather than interleaved with it, also reduces the chance that stylistic instructions bleed into how the model renders the factual details, which need to stay plain and legible even when the rest of the poster is stylistically loud.
