Don’t let a bad print ruin your day. Here are the most common sublimation snags and how to dodge them. We’ve already solved these tricky printing puzzles for hundreds of others—let us do the same for you.

#1 – Incorrect Temperature and Time Settings

When the temperature dips too low, sublimation ink just won’t do its thing, and if it gets too hot, you might end up ruining your substrate or getting a burnt image. Similarly, Excessive pressure may result in permanent ‘press lines’ or indentations, particularly on textile substrates. Conversely, insufficient pressure prevents complete ink sublimation, leading to faded or inconsistent color density.

• Tip: Always do a test print when experimenting with new products. Feel free to contact our technical team beforehand so we can provide the best advice for your specific machine!

Key details to watch for:

• The “Yellowing” Sign: If your white polyester fabric starts to turn yellow or brown, your temperature is too high or the time is too long.
• Ghosting: If you move the paper while it is still hot, the lingering gas can create a “shadow” or ghost image. Use heat-resistant tape to keep everything locked in place.
• Cold Spots: If your image is faded only in certain corners, your heat press may have uneven heating elements or you are using insufficient pressure.

#2 –  Not Using the Right Sublimation Ink

Utilizing non-sublimation or incompatible inks may lead to low-quality prints and clogged printheads.

• Tip: Always utilize sublimation inks  that are specifically tailored for your printer model. Additionally, Always monitor ink levels through your printer software and replace cartridges as needed before they run out completely. 

#3 – Using Incorrect Sublimation Paper

Not every sublimation paper is the same, and choosing the wrong one can result in various problems, including inadequate ink transfer, ghosting, and bleed-through.

• Tip: Ensure that you are using a premium sublimation paper  that is tailored for the specific substrate you are printing on.

#4 –  Don’t Rush the Reveal

When you extract the product and take off the sublimation paper significantly impacts your end result.

• Tip: After transferring your design to the substrate, be sure to let the item cool all the way down before you handle it or remove it from the heat press.

#5 – Overlooking Color Management

If your printed transfers lack vibrancy, it might be due to low ink levels or ineffective color management.

• Tip: Take a moment to create a color-managed workflow. Plus, make sure you have the correct color profile set up.

Think of an ICC (International Color Consortium) profile as the “secret recipe” for your printer. As explained in our guide on why printer profiles matter , this file acts as a translator between your computer screen and your printer.

#6 – Failing to Pre-Press Garments or Substrates

Moisture trapped in fabric can be a hidden enemy in sublimation.

• Tip: Clean your surface to ensure a perfect ink bond.

1. For Hard Surfaces: Wipe with a lint-free cloth and isopropyl alcohol to remove oils and dust that cause spots.
2. For Textiles: Use a lint roller to remove debris, then pre-press for 5 seconds to flatten fibers and vent moisture. This prevents steam-related “ghosting” and ensures vibrant colors.

Bonus Tip:  Always Use a Dedicated Sublimation Oven, and reserve it solely for sublimation tasks. Never use the same oven for food and sublimation. Sublimation ink releases toxic fumes when heated, which can contaminate your food oven and pose health risks.
