Why are my sublimation prints faded or dull?

Faded or dull sublimation prints are often caused by incorrect temperature, pressing time, or low-quality ink. To fix it, use the correct heat settings, high-quality sublimation ink, and ensure even pressure during pressing.

What causes ghosting in sublimation printing?

Ghosting is caused by the transfer paper shifting during pressing or using too much pressure. Secure your transfer paper with heat-resistant tape and reduce pressure on curved surfaces.

Why are my sublimation colors off or mismatched?

Incorrect color profiles or poor-quality sublimation paper are the usual causes. Calibrate your printer with the correct ICC profile and use compatible sublimation paper.

Why is my sublimation ink not transferring to the mug?

This could be due to low heat or incompatible sublimation paper. Use a heat gun to verify temperature and choose high-quality, instant-dry sublimation paper.

Why do my sublimation prints crack?

Cracking occurs when the mug is cooled too quickly, such as under cold water. Let it cool gradually using a fan or swamp cooler to prevent thermal shock.

💔 Stopping Cracks in Sublimation Prints

Cause: Cooling the mug too quickly (e.g., running under cold water).

Solution: Allow mugs to cool gradually using a fan or ambient air to prevent thermal shock.

🌀 Preventing Blurry Sublimation Prints

Cause: Sublimation process continues while the mug is still hot.

Solution: Use a fan to quickly but gradually stop sublimation and maintain print sharpness.

🖨️ Fixing Ink That Doesn’t Transfer to the Mug

Causes: Low heat settings or incompatible transfer paper.

Solutions:

Double-check your heat settings using a heat gun. Target range: 375–400°F for 3–5 minutes.
Only use high-quality, instant-dry sublimation paper.

Cause: Ink is still wet when printer rollers touch the paper.

Solutions:

Use instant-dry sublimation paper.
Disable bi-directional printing and enable quiet mode to slow print speed.
This issue is more common in converted inkjet printers.

🔥 Pro Tips for Better Sublimation Results

Invest in a true sublimation printer. These are designed for sublimation ink and come with auto-cleaning features.
Use manufacturer-recommended ink. While it may cost slightly more, it results in better color and longer-lasting prints.
Longevity Matters: A dedicated sublimation printer can last up to 5 years vs. 12–18 months for a converted inkjet.
Time is money: A reliable setup saves 1–2 hours weekly on troubleshooting.
