Write the communication brief before the image prompt
A neighbourhood gym advertising a quiet beginner session has a different job from a sports brand launching new shoes. Specify who should notice the poster, where they see it, what doubt it must resolve and what action they should take. A bus-shelter poster has seconds to communicate; an event notice on a reception desk can carry more detail.
Collect the offer, proof, deadline, legal copy and approved logo before designing. A beautiful visual cannot repair an ambiguous offer.
Develop a poster brief for [offer] aimed at [audience] in [placement]. The audience currently thinks [barrier]. We can credibly prove [evidence]. The desired action is [action]. Define one primary message, one supporting fact and a call to action. Ask about missing offer details before writing final copy.
Choose a concept rather than a decoration
Ask for concept routes that make different arguments. For the beginner gym session, one route could show the first manageable step; another could use the relaxed environment; a third could answer a practical anxiety. Changing only the colour does not make them different concepts.
Name overused category imagery you want to avoid, then explain why. Rejecting ‘generic’ alone gives no positive direction.
Propose four poster concepts for this brief. Each must use a different persuasive idea. For each, provide a headline, the central visual, why it fits this audience and the risk of misunderstanding. Avoid [category clichés]. Select one after comparing clarity, originality and brand fit.
Translate your house style into visible rules
Give the model approved assets, colour values and examples. Specify where the logo belongs, which typography is fixed and what should remain editable. For a precise wordmark or long legal text, reserve space and place the original asset in a layout tool. Do not ask a generated imitation to stand in for an approved logo.
Create the central visual for the approved concept using [references]. Use [colour roles], [lighting] and [composition]. Keep [area] clear for the headline and [area] clear for the original logo. Add no text. Preserve the product details in [reference]. Output at [orientation] for the layout stage.
Check the actual poster, not just the picture
Put the visual into the intended layout, add exact copy and view it at realistic reading distance. Check which element your eye reaches first. Verify the URL, date, price and call to action. For print, confirm trim, bleed, colour handling and resolution with the production provider.
Treat model choice as a production decision. Faster image drafts can help select a concept; a stronger visual model may help a difficult final image. Neither replaces proofreading or a print check.
Review this assembled poster for [placement]. Identify the first thing a viewer notices, the message they can understand in three seconds and anything that competes with the call to action. Check the supplied copy exactly. Separate visible problems from opinions that need audience testing.
Worked brief: a first visit, not a fitness fantasy
Illustrative scenario: a local gym wants beginners to try a quiet introductory session. Its reader worries about not knowing the equipment, not about finding motivation. A vague request for an ‘inspiring fitness poster’ could produce a dramatic athlete who reinforces that anxiety. The useful creative problem is making the first visit feel manageable.
A stronger brief supplies a real session format, an approved offer and evidence of the support provided. One concept might show a clearly marked first step; another might show the actual coach and familiar reception area. Those are directions to test, not claims that one will convert better. Use genuine venue imagery or label illustrative imagery appropriately.
Illustrative campaign brief: our beginner session includes [verified support] at [actual venue]. The audience worries about [specific first-visit concern]. Create three poster concepts that reduce that concern without promising results. Use our approved [colours, type and photography rules]. Keep [exact offer] and [booking action] prominent. For each concept explain the visual, headline, evidence required and what could accidentally make a beginner feel excluded.
Before and after: a poster people can act on
Weak prompt: ‘Make a beautiful, professional poster for my bike shop.’ This asks for a look without explaining the offer, reader, placement or action. Adding ‘award-winning’ or ‘not generic’ still leaves the creative problem undefined.
The stronger illustrative brief below separates concept development from final production. Replace the sample offer with your verified details. If you have no brand guide, provide two approved examples and explain what to preserve; do not ask the model to guess your house style from the business name.
- Offer check: are the price, duration, inclusions and exclusions still accurate?
- Distinctiveness check: do the three concepts express different ideas, or merely different decoration?
- Production check: after approval, inspect legibility at window distance and verify the final URL, logo and print requirements.
Develop three genuinely different A3 window-poster concepts for a local bicycle workshop. Audience: everyday commuters who keep postponing routine maintenance. Illustrative offer: a €29, 30-minute bike check covering brakes, tyres and lights; repairs and parts are extra. Action: book at [verified URL]. Brand: navy and yellow, plain typography, practical and welcoming language, genuine workshop photography. Avoid racing imagery, fear-based claims and invented safety guarantees. For each concept give one visual idea, a headline of at most eight words, exact supporting copy and the intended reading order. Explain how the concepts differ in persuasion, not just colour. Flag missing assets. Do not generate the final artwork yet; wait for concept approval. Preserve the original logo and exact offer in the final editable layout.
Common questions
Can I ask for a poster in my own brand style?
Yes. Supply approved references, colour roles, typography rules and exact assets. Preserve logos and mandatory copy in an editable layout rather than accepting a generated approximation.
How do I make an AI poster less generic?
Give it a specific audience tension and a distinctive visual idea. Compare different persuasive concepts before choosing a style.
