”TL;DR — Most AI generators spit out gorgeous images at 512 × 512 px or 1024 × 1024 px—great for screens, terrible for posters or tees. In this guide you’ll learn exactly how to turn those low‑res pixels into crisp, gallery‑quality prints in minutes using our automatic upscaling and print‑on‑demand workflow.
Why Resolution Matters (and What DPI Really Means)
- Resolution (pixels) is the raw width × height of your image. More pixels = more detail.
- DPI/PPI (dots / pixels per inch) is how tightly those pixels are packed when printed. For pro‑quality prints you want 300 DPI at the final size.
- A 512 px image printed at 300 DPI is barely 1.7 inches wide—no wonder it looks blurry on a 12‑inch canvas!
| Desired print size | Minimum pixels needed (300 DPI) |
|---|---|
| 8 × 10 in poster | 2400 × 3000 px |
| 12 × 18 in wall art | 3600 × 5400 px |
| 24 × 36 in poster | 7200 × 10 800 px |
| Unisex T‑shirt (front, 12 in area) | 3600 × 3600 px |
Step 1 — Generate & Export Your AI Image
- Prompt smart: If your generator supports higher native resolutions (e.g. Midjourney v6’s –ar / –w / –h flags), use them.
- Save as PNG: Avoid JPEG artifacts—PNG preserves detail and transparency.
- Keep originals: We’ll feed the PNG straight into the upscaler.
Pro tip: When prompting, leave space around the subject if you plan to print on apparel; tight edge‑to‑edge designs can get cut off by seam tolerances.
Step 2 — Let Our Upscaler Do the Heavy Lifting
Upload your PNG to the dashboard and watch the magic:
- Generative upscaling in ~10 seconds (yes, that 512 px image becomes 4096 px or more).
- Edge enhancement & noise cleanup so lines stay sharp even on large canvases.
Why not DIY?
- Manual tools like Topaz (Paid) or free ESRGAN require installs, settings, GPU time, and still need a POD workflow.
- Here, upscaling is one click and free with every print order.
Step 3 — Choose the Perfect Product & Size
Just upload, adjust size and position and you’re done!
| Category | Popular sizes |
| Wall Art | 12 × 18 in → 24 × 36 in |
| Apparel | Front‑print area up to 15 in |
| Phone Cases | Fits all major models |
| Desk Gear | 9 × 7 in mouse pads |
Step 4 — Preview, Crop & Add Finishing Touches
- Safe print zone overlay helps you keep vital elements away from edges.
- Need text or a second image? Use the built‑in layer editor without leaving the page.
Step 5 — Checkout & Track Your Print
- Select quantity & shipping method (standard or express).
- Real‑time order tracking—from printer to your door.
Typical turnaround: 2–4 business days production + shipping. Yes, that means your AI masterpiece can be on your wall in under a week.
