Short answer
Create a single source-of-truth “brand style prompt” (images + keywords + param set) and use it as the first line of every Midjourney job. Pair that with a routine QA checklist (color, scale, logo placement, seed reuse) and a small prompt library for common campaign formats.
Recommendation
Build a reproducible prompt block that lives in your brand assets repo and is copied into every `/imagine` job. Version it when you change the visual language. Use image references + exact hex colors + a fixed set of MJ params (version, stylize, aspect ratio, seed, quality) to lock in style.
How to structure prompts (template + examples)
Basic structure (replace placeholders):
[brand_ref1.jpg::0.7] [brand_ref2.jpg::0.3] /imagine prompt: , , color palette: #001F3F, #F2C94C, #FFFFFF, materials: matte paper, soft shadows, flat highlights, composition: centered hero, negative: --no clutter --no text --no extra-figures --no watermark --ar 16:9 --v 6 --stylize 50 --seed 12345 --q 2
Hero campaign example:
[brand_mood.jpg::0.8] /imagine prompt: young professional using product on city rooftop, minimalist composition, warm evening light, brand tone: calm, optimistic, flat mid-contrast, color palette #164A6C #F2C94C, clean iconography, --ar 16:9 --v 6 --stylize 40 --seed 24680 --q 2 --no logos --no text
Product mockup example:
[product_ref.jpg::1] /imagine prompt: close-up product on matte pedestal, soft rim light, neutral background with brand gradient #001F3F->#FFFFFF, crisp edges, photoreal, --ar 4:5 --v 6 --stylize 10 --seed 13579 --q 2 --no people
Decision criteria — when to use this workflow
- Use Midjourney when you need rapid, stylistically consistent visuals across social/ads/hero images and you can tolerate some post-compositing. Good for small-to-medium teams and mid-range budgets.
- Avoid if you need exact vector logos, pixel-perfect product renders, or strict legal provenance — use in-house design or 3D renders instead.
- If absolute color matching (print, packaging) is required, expect manual adjustments in Photoshop/Illustrator and physical proofs.
Best-for / Avoid-if
- Best for: campaign mood images, illustrations, backgrounds, lifestyle hero shots.
- Avoid if: final print CMYK-critical packaging, regulated industries that require provenance for imagery, or if you need editable vector artwork.
Practical routine checklist (use before publishing)
1) Reference/Source: Confirm the same brand_ref images and weights used.
2) Color check: sample hexes; compare to master palette; adjust lighting and re-render if Delta noticeable.
3) Seed reuse: keep seed numbers in filenames for reproducibility.
4) Aspect ratio variations: re-run with same prompt + --ar variants.
5) Remove artifacts: use --no and upscaler options or manual retouch.
6) Logo & type: never rely on MJ to generate logos; composite approved vector logos in post.
7) Legal/rights: archive prompt + image inputs + MJ version for provenance.
8) QA pass: designer checks composition, brand tone, color swatches, accessibility (contrast).
9) Version control: commit prompt and final outputs to brand repo with change notes.
Workflow tips
- Keep a short prompt library for repeat formats (hero, carousel, background, product).
- Use a small set of seeds and record them.
- Use ChatGPT to standardize prompt phrasing and generate variations quickly.
