Sick of scorched fabrics and faded colors when sublimating? It’s frustrating when your designs don’t transfer cleanly. But don’t despair – using heat tape is an easy fix to start achieving eye-catching prints.
In this guide, we’ll explore how heat tape protects your fabrics during sublimation. With a few application tips, you’ll immediately notice crisper, more vivid images. Let’s dive in!
An Overview of Dye Sublimation Printing
First, a quick sublimation refresher. This popular printing technique uses special sublimation inks to permanently imprint fabrics, woods, and other polymer-coated surfaces.
Choosing the right sublimation ink is key – you’ll want long-lasting inks designed to stand up to repeated heat pressing. Be mindful of the shelf life of sublimation inks as they can expire and clog printheads.
When exposed to high heat around 400°F, the inks convert directly from solid to gas. The ink vapor bonds with the polymer fibers to create full color images that won’t crack or fade.
It’s an incredibly effective process, but the intense heat can actually damage many fabric types. This heat exposure during sublimation is where heat tape comes to the rescue.

Why Heat Tape is Vital for Quality Sublimation
Heat tape forms a protective layer that saves your fabric from scorching during the high temperature sublimation process.
It’s a thin, heat-resistant tape that shields fabrics to ensure perfect prints. Without it, your materials are at risk.
Here are the key reasons heat tape is a sublimation essential:
Prevents Scorching and Melting
The 400°F+ heat will singe natural fibers like cotton or melt synthetics like polyester. Heat tape prevents these damages.
Allows Diverse Fabric Choices
More delicate textiles can be sublimated when shielded by heat tape. Expand options beyond just polyester.
Conserves Fabric for Testing
Reuse fabric swatches worry-free when protected by tape. Save money testing print settings.
Reusable for Many Projects
One piece of heat tape can assist in hundreds of pressings. A budget-friendly solution.
Heat tape is easily found online and in craft stores. No specialty supplier needed.
Let’s explore how to pick the right heat tape to unleash its protective powers.
Choosing the Best Heat Tape for Pristine Sublimation
With heat tape, quality matters. Be sure to select tape that can withstand repeated 400°F+ exposure. Check for these key properties:
- Temperature rating over 400°F – Confirmed high heat tolerance.
- Silicone-coated fiberglass material – Withstands heat without losing integrity.
- 10-15 mil thickness – Enough to protect while minimizing bulk.
- High tack adhesive – Bonds securely to fabric surface.
- Sheet format – Easier to position than thin rolls.
- Dimensionally stable – Won’t shrink or expand at high temps.
Tape meeting these criteria will shield fabrics during repeated sublimation presses. Now let’s get it applied.
Applying Heat Tape for Sublimation
Installing heat tape only takes a few quick steps:
- Cut the tape 1-2 inches larger than your design size.
- Remove the adhesive backing.
- Smooth the tape onto the fabric, pressing firmly.
- Slowly peel away bubbles or wrinkles.
- Secure the edges with extra adhesive if needed.
And your fabric is prepped for crisp, vibrant sublimation!
“I can’t get over how easy it is to apply the tape. My fabrics are protected in just minutes!”
Now if your heat tape is leaving marks there can be various reasons for that, read this guide on why is my heat tape leaving marks for in-depth reasons of heat tape marks and how to avoid them.
Next, we’ll walk through the full sublimation process with your heat tape assist.
Step-by-Step Sublimation with Heat Tape
Follow these best practices:
- With your fabric shielded by heat tape, position the transfer paper ink-side down.
- Press at 400°F for 30-60 seconds using firm, even pressure.
- For a pattern repeat, reposition the transfer paper and press again.
- Once cooled, carefully peel away the heat tape to reveal the print.
- Finally, peel the transfer paper and admire your work!
The heat tape prevents any scorching so the colors stay bold and vibrant. But one mistake to avoid…
Don’t leave the tape on too long once cooled, or the adhesive can break down and damage fabric. Promptly remove it after sublimation.
“Using heat tape let me press fabrics I never thought I could sublimate without issues. My prints are flawless!”
The results speak for themselves. But for maximum cost savings, you’ll want to reuse your heat tape. Here’s how.
Removing and Reusing Heat Tape
With some basic care, heat tape can be reused for many sublimation projects:
- Allow tape to fully cool after pressing before removal.
- Slowly peel the tape away at a 180° angle.
- Gently remove any adhesive left behind with remover spray.
- Store the removed tape flat in a ziplock bag.
- To reapply, re-adhere the tape firmly from one edge.
- Replace tape after about 15-20 repeated uses as adhesion decreases.
A little maintenance goes a long way for maximizing the value of your heat tape purchase.
Key Takeaways for Quality Results
To recap, remember these tips:
- Use heat tape to protect fabrics from 400°F+ sublimation heat.
- Select heat tape that withstands high temperatures.
- Cut tape larger than your design and apply firmly.
- Promptly remove tape after sublimation to avoid adhesive issues.
- With care, heat tape can be reused 15-20 times.
- Replace tape once adhesion starts to decrease.
Follow these guidelines and heat tape will ensure your sublimated prints come out perfect every time! No more scorching or fading.
