Plakaty social: jeden koncept, wszystkie platformy

The pain point for ops teams is rarely “can’t draw”—it’s one campaign needing five sizes, three copy variants, and two languages. AI Image 2 shines with accurate text + switchable ratios + Thinking batches. This tutorial gives you a copyable social poster production line.

Platform size quick reference (2026 common)

Pick a master KV at 16:9 or 3:4 first, then derive other sizes.

Workflow overview (90 minutes per campaign)

Brief sheet → Thinking master KV → curate pick 1 → ratio switch derivatives → local copy edits → export naming → schedule upload

Step 1: Campaign brief sheet (copy template)

Step 2: Master KV prompt (3:4 cover example)

Thinking mode, social cover 3:4 portrait.

[Copy] Main headline "More Than Half Off" (large bold), subhead "Jun 1–18 storewide" smaller.
[Scene] Center product group: sunscreen + sunglasses, summer beach bokeh background,
brand accent #E63946, bright commercial photography, headline in upper third.
[Forbidden] Garbled text, watermarks, malformed fingers.

Generate 4 candidates → pick 1 for Step 3.

Step 3: Ratio derivatives (no creative rewrite)

Based on the previous image:
1) Change to 16:9 landscape, headline left, product right, for feed posts.
2) Change to 1:1 square, headline centered top, product centered, for Instagram.
3) Change to 9:16 vertical Story, headline shifted up 15% safe zone, product lower center.
Keep colors and product consistent each time.

Request three ratios in one message or split into three for stability.

Step 4: Multilingual variants

Layout identical to the previous image, only replace copy:
Title "SUMMER SALE", subhead "Up to 50% Off · Jun 1–18"

Japanese and Korean work the same way; for RTL (Arabic) prefer text-free image + localized overlay.

Step 5: Text-free version + post overlay (insurance)

Thinking mode, 3:4 summer beach product scene,
reserve upper 30% solid gradient whitespace for later typography,
no text at all.

Designers overlay brand fonts in Figma / Canva—change pricing on launch day without re-running AI.

Step 6: File naming and archive

Scheduling and A/B

Compliance reminders

• Avoid unverified superlatives like “best” or “#1”
• Promo dates and prices must match backend config
• Portrait rights: label AI faces or use faceless compositions

Today’s challenge

Pick a real campaign (even internal test) and deliver in 90 minutes:

• 1× 3:4 master KV
• 2× derived ratios
• 1× text-free backup

After that, your social poster output upgrades from “single-card luck” to a schedulable production line.
