Design Text-Rich Campaign Posters With Seedream 5.5

A promotional poster must do more than look atmospheric. It has to communicate a headline, an offer, and a next action in a hierarchy that still works on a phone screen. That makes typography one of the hardest parts of AI poster generation.

Dreamina's official Seedream 5.5 preview highlights detailed posters, coordinated colors, text rendering, visual hierarchy, and layout adaptation. It also advises users to proofread small text and verify facts. The safest workflow combines AI layout exploration with a strict copy review.

Start with an approved copy sheet

Do not ask the model to invent campaign claims. Lock the copy before building the design.

Copy role	Example	Rule
Headline	MIDNIGHT MARKET	Short and visually dominant
Subheadline	Independent fashion after dark	One concise supporting line
Date	NOV 21–23	Verify against the event plan
Location	EAST HALL · LEVEL 2	Use exact approved spelling
CTA	BOOK YOUR SLOT	One clear action

Poster prompt framework

Campaign purpose + exact copy + hierarchy + subject + composition + palette + typography direction + aspect ratio + exclusions

Prompt starting point

Create a vertical 4:5 fashion event poster for an independent night market. Use a deep ink-black background, muted silver textures, and one electric-cobalt accent. Center a sculptural chrome handbag in a dramatic spotlight with generous negative space.

Render the following approved English copy exactly:
Headline: “MIDNIGHT MARKET”
Subheadline: “Independent fashion after dark”
Date: “NOV 21–23”
Location: “EAST HALL · LEVEL 2”
CTA: “BOOK YOUR SLOT”

Use a clear hierarchy: the headline is the largest element at the top, the product is the central focus, event details sit in a compact lower grid, and the CTA appears at the bottom. Use editorial display typography with high contrast and clean spacing. Do not add extra slogans, prices, logos, watermarks, decorative filler text, or illegible microcopy.

This is an untested starting prompt based on official capability descriptions, not a verified output claim.

Step 1: Generate the hierarchy before the decoration

Begin with one hero subject and five or fewer text elements. If the hierarchy fails, adding textures and ornaments will not fix it.

Step 2: Review at thumbnail size

Shrink the poster to the size it will occupy in a feed. The headline, subject, and CTA should remain distinct. If every element competes for attention, simplify the layout.

Step 3: Proofread at full size

Check every character, punctuation mark, date, number, price, and location. Generated text may look plausible while containing incorrect letters.

Step 4: Separate layout approval from copy approval

A strong composition can still contain unusable text. If exact wording fails, preserve the visual concept and replace the final typography in a conventional design tool.

Step 5: Adapt the approved design

Create new aspect ratios only after the key layout works. Re-state the hierarchy for each format rather than asking the model to “resize” without guidance.

Publish only after these checks

• All copy matches the approved source exactly.
• Dates, locations, prices, and claims are factually correct.
• No extra pseudo-text appears in the background.
• The CTA is readable on mobile.
• Brand colors and product details remain accurate.
• Copyrighted logos and typefaces are used with permission.
• A human designer has reviewed the final production file.
