The mirror-print checklist every sublimation maker needs

A short pre-press checklist that stops the most expensive sublimation mistake — printing artwork the right way round.

The single most expensive sublimation mistake is forgetting to mirror your artwork. The press transfers a backwards print onto your blank with no recovery.

Also known as: dog leash sleeve, personalized dog leash, custom dog leash, leash cover, lead wrap. Lead Sleeve ships worldwide — UK, US, EU, Canada, Australia, Asia, LATAM.

Pre-press

  1. Open the export-ready file (not the working file).
  2. Confirm the artwork is mirrored — text should be backwards on paper.
  3. Confirm final print size, not scaled.
  4. Confirm ICC profile selected.
  5. Confirm "printer manages colour" is off.
  6. Load fresh sublimation paper, coated side up.

At the press

  1. Pre-press the blank for 5–10s to remove moisture.
  2. Lay flat. Slip a card inside a sleeve.
  3. Place printed paper face-down (printed side touches blank).
  4. Tape paper down.
  5. Cover with butcher paper.
  6. Press at recommended settings.
  7. Don't open early.
  8. Peel while warm. Inspect.

Post-press

  • Photograph good units immediately.
  • Bag and label rejects so you don't ship them.
  • Log time, temperature, outcome for the first month.

Print this list and stick it above your press.
