Artwork help

A short guide to preparing files that print beautifully. If you are unsure about anything, send the file over on WhatsApp and our studio will check it for you before you order.

The quick version

  • • Upload JPG, PNG or WebP (up to 25MB) at the highest quality your device can export.
  • • 300 dpi at print size is the professional reference, but larger posters are viewed from further away and print sharply below it. The editor checks your exact file at your chosen size.
  • • Keep important content 5 mm inside the edges so nothing gets trimmed.
  • • Upload in sRGB colour and expect prints to look slightly less vibrant than your screen.

Printing AI-generated artwork

Uploading a Midjourney, DALL·E, ChatGPT, Canva or Firefly image? A few extra checks help it print sharp at A3 and above.

  • • Download the original file from your AI tool - not a screenshot.
  • • Upscale where possible; most tools offer a “creative upscale” or “HD” export.
  • • Avoid small compressed previews shared via chat or social media.
  • • Save as PNG (best for sharp edges) or high-quality JPG.
  • • Check faces, hands, text and spelling before ordering - AI can drift on details.
  • • Upload the highest-resolution version you have.

FAQ

What file formats do you accept?

JPG, PNG and WebP, up to 25MB per file. PDF and SVG are not supported. For photos, JPG at the highest quality setting is ideal. For designs with text or flat colour, PNG keeps edges crisp.

What resolution should my file be?

For reference, 300 dpi at print size is the professional standard. As a rough guide: A4 = 2480 × 3508 px, A3 = 3508 × 4961 px, A2 = 4961 × 7016 px, A1 = 7016 × 9933 px. Larger sizes are viewed from further away, so prints still look sharp below 300 dpi. Most recent phone photos print well up to A2 or A3, but it depends on the specific file - the editor's image-quality check gives a definite answer before you order.

Do I need to add bleed?

No. We handle bleed for you. Just keep important content and text about 5 mm inside the edge so nothing important sits in the trim area.

RGB or CMYK?

Upload in sRGB. Our print workflow converts to the printer profile for the best possible colour match.

Why does my print look darker than my screen?

Screens are backlit; paper reflects light. If your image is very dark to begin with, brighten mid-tones by 10 – 15% before uploading.
