Как дизайнить постеры с ИИ в Krea 2

Постер — это не обои, на которые потом «наклеили» текст. Он должен остановить прохожего через комнату, выдержать phone thumbnail и оставить чистое место под title, date и credits. Поэтому generic AI renders так часто проваливаются: они заполняют каждый край деталями и не оставляют места для дизайна.

Этот гайд — poster spoke в кластере Krea 2. Определение продукта и карта скоростных тиров — на what Krea 2 is. Грамматика промпта — в prompt guide. Здесь unique job — key-art crops, type-safe composition, print- и channel-checks. Helpful, people-first standard Google — тот же north star: one purpose, clear hierarchy и original utility.

Ключевые выводы

• Сначала crop и type hierarchy, потом style adjectives.
• Успех постера оценивают на двух дистанциях: wall size и thumbnail size.
• Reserve quiet zone под headline и date; не генерируйте edge-to-edge chaos.
• Держите in-image text коротким или оставляйте title layout software.
• Explore → stabilize → finalize по shared tier map на product hub.
• Для cover и quote assets используйте их guides; у постеров другие safe-zone rules.

Чем постер отличается от cover или quote card

До любого промпта назовите job:

Asset	Primary success test	Type need	Canonical guide
Poster	Останавливает прохожего и читается small	Large headline + date / venue	this page
Book or album cover	Thumbnail genre signal	Series consistency under shrink	cover maker
Quote graphic	Supports overlaid words	Large calm negative space	quote maker

Постеры живут в public или campaign space. Они должны передавать hierarchy с метров, а затем всё равно работать после reduction for social and web. Classic print sizes вроде 18×24 и 24×36 близки к семьям 3:4 или 2:3, а one-sheet cinema обычно обсуждают вокруг tall portrait ratios near 27×40 (poster size chart; print aspect ratios). Digital stories уходят в 9:16. Generation crop must match first channel, not a random square.

Step 1: выберите crop до vibes

Сопоставьте crop destination:

• 3:4 classic print, gig posters, many retail boards
• 2:3 / tall portrait larger wall prints и many film poster layouts
• 9:16 stories, vertical screens, transit digital
• 16:9 wide key art, web heroes, YouTube-adjacent banners
• 1:1 only when first publish surface is truly square

Если wrong crop first, вы потратите всю сессию, fighting the composition. Пропишите ratio как часть brief, чтобы модель budgets space for subject and type from frame one.

Step 2: пишите key-art brief, а не wallpaper prompt

Ведите subject action, затем lighting, palette, lens feel и type plan:

Theatrical film poster: a lone climber on a windswept ridge under aurora, dramatic low-angle cinematic light, deep indigo and amber palette, shallow depth of field, open sky in the top third for title, photoreal, 3:4

Music event poster: neon-soaked alley after rain, glossy reflections, high-contrast synthwave cyan and magenta, subject lower third, clean upper field for headline, 9:16

Key-art language берёт у movie poster anatomy: dominant figure or symbol, controlled silhouette, strong contrast и intentional empty areas for typography (movie poster anatomy overview). Soft ambient filler редко wins this job.

Research surveys on text-to-image systems всё ещё показывают residual control and fine-structure failures even as surface fidelity rises (Zhang et al., arXiv 2025; Croitoru et al., diffusion survey). Poster work makes those failures obvious, потому что hierarchy и silhouette non-negotiable.

Step 3: направляйте composition для type и hierarchy

Постер — composition system, а не single pretty subject.

Скажите модели, где energy и quiet:

• subject low, open sky or wall above for the headline
• subject left or right, clean panel opposite for title stack
• tight hero portrait with strong rim light and calm background mass
• wide establishing shot only when scale is the story

Избегайте full-frame busy textures. Они look impressive in the generator и fail the moment real type lands.

In-image text vs post layout

Два валидных path:

1. Type later in design software (обычно safer): generate a clean art plate with reserved negative space.
2. Short text in-image: quote only a short title or single word, keep letterforms huge and sparse.

Long credit blocks, fine print и multi-line billing — poor generation targets. Treat them as layout layers, not prompt magic.

Step 4: two-distance review

Используйте этот метод тестирования before you call a draft finished:

1. View at full desktop width for wall presence.
2. Shrink to a phone-list thumbnail and cover the center with one finger.
3. Ask whether subject silhouette and mood still read.
4. Drop a temporary title block into the quiet zone and check contrast.
5. Export one print-oriented crop and one social crop without recomposing from scratch if possible.

If the frame only works large, it is illustration for desktop, not a poster system. If it only works tiny, it is a social stamp, not key art.

Google's public creative systems keep returning to immediate recognition and clear hierarchy over decorative density (helpful content guide; YouTube ABCD creative playbook, Think with Google). Posters are the still-image version of the same idea: one point of focus first.

Step 5: iterate with constraints, then finish high

When a draft is close, send it back as a reference and change one of:

• crop pressure (more sky / more ground)
• palette temperature
• rim light strength
• subject scale
• background quietness

Do not re-roll everything because one title area is noisy. For explore-stabilize-finalize economics, use the shared tier map on the product hub. Keep product pricing and endpoint names there so this page stays about poster craft.

Poster prompt recipes by channel

Event / concert poster

Night festival poster: singer under harsh spot from above, haze, crowd silhouettes low in frame, hot red and violet palette, high contrast, open upper sky for title and date, 3:4

Product launch poster

Premium product launch key art: single object on dark stage, controlled specular highlights, cool silver and graphite palette, soft falloff, left third clean for brand lockup, 16:9

Film or series teaser

Cinematic teaser poster: two figures at a rain-slick crossroads, sodium streetlight, deep teal shadows, strong silhouette, negative space top for stacked title treatment, 2:3

Vertical social poster

Vertical campaign poster: portrait subject looking off-camera, soft rim light, muted earth palette, lower third graphic band reserved for short CTA, 9:16

Reuse the recipes. Swap subject and palette, hold the hierarchy logic.

Print and export checklist

Before client or print handoff:

• type contrast holds at actual reading distance
• no critical detail in bleed or rail cut zones
• date, venue, and legal remain layout layers when too small for image generation
• series variants share light quality and palette grammar
• commercial rights reviewed against current plan and support terms
• product crop options confirmed on the models documentation before bulk renders

Treat AI output as an art plate you finish, not a one-click final PDF. Questions about accounts can go through contact.

Common failure modes (and the fix)

Failure	Why it happens	Fix
Beautiful frame, no title space	Prompt never reserved quiet mass	Add "open upper third for headline"
Reads large, dies small	Low contrast silhouette	Push rim light and simplify background
Text looks broken	Long in-image copy	Shorten to 1-3 words or set type later
Series looks random	New roll every time	Reference the winning plate and change only subject or hue
Crop fights the channel	Square concept forced into tall print	Restart from the correct ratio

Artifact writeups around plastic surfaces and dense midtones are useful when frames feel AI-glossy at print size (ZSky artifacts guide). If light, skin, or product materials still fail a full-size material review, run the photoreal workflow checks before locking type hierarchy.

FAQ

Can AI design a finished print-ready poster alone?

Usually no. AI is strong at the key-art plate. Hierarchy, legal type, and production files still need a design pass.

Should poster titles be generated inside the image?

Only for short display words. Long titles and multi-line credits are more reliable as layout layers over a clean plate.

What crop should I start with for a gig poster?

Start with 3:4 or a tall portrait ratio that matches your print shop, then create vertical social adaptations. Do not invent the print after the square is already full of detail.

How is this different from the cover guide?

Covers prioritize thumbnail genre read and series continuity. Posters prioritize wall stop-power plus large type hierarchy. Use the cover spoke for books and albums.

Where do speed tiers fit?

They fit the shared explore-stabilize-finalize path documented on the product hub. This page stays focused on poster-specific composition and export quality.

Bottom line

How to design posters with AI using Krea 2 — mostly a hierarchy problem:

1. pick the real crop
2. write a key-art brief with a title plan
3. protect quiet zones
4. judge at wall and thumbnail distance
5. iterate one constraint at a time
6. finish type and production outside the generator when needed

Open the generator, start from one recipe above, and keep the quiet zone sacred. For product fit return to the hub; for wording mechanics use the prompt guide.
