What Is Sublimation Printing And How Does It Work

Dye Based Inks

Sublimation printing didn't emerge overnight. Its roots date back to the 1950s, when scientists began experimenting with dye-based inks that could change states under specific heat and pressure. However, it wasn’t until the 1980s and 1990s that sublimation printing became commercially viable, with the introduction of sublimation printers, heat presses, and polyester-based substrates.

Today, advancements in digital printing technology, ink chemistry, and automated machinery have made sublimation accessible for both small-scale entrepreneurs and large production units.

Key milestones:

• 1950s: Sublimation chemistry discovered

• 1980s: First thermal transfer printers introduced

• 1990s: Entry into textile industry

• 2000s–Present: Digital sublimation dominates custom printing markets

Phase Transition

3.1 What is Sublimation?

Sublimation is a phase transition in which a substance moves directly from a solid state to a gaseous state without becoming a liquid. In sublimation printing, special dyes are used that sublimate under heat and pressure, allowing them to penetrate the surface of a substrate.

3.2 How Does Sublimation Printing Work?

The process begins with printing a mirrored image using sublimation ink on transfer paper. This paper is then aligned with the target substrate (usually polyester or a coated surface) and placed into a heat press. When exposed to temperatures around 380-400°F (190-204°C) and pressure for 30-60 seconds, the ink sublimates into gas and bonds with the polymer molecules of the substrate.

Key Steps:

1. Design creation using graphic software
2. Printing onto sublimation transfer paper
3. Heat pressing onto target material
4. Ink transforms and fuses with substrate
5. Result: Permanent, high-resolution image

Textile Printing

5.1 Desktop Sublimation Printing

Ideal for small businesses and home setups. Uses A4/A3 sublimation printers to create custom products like mugs, t-shirts, and keychains.

5.2 Wide-Format Sublimation

Used in industrial textile printing. Machines print on rolls of paper or fabric, suitable for sportswear, fashion, flags, and banners.

5.3 Direct-to-Fabric (DTF) Sublimation

In this method, printing is done directly on pre-treated fabric without the use of transfer paper, streamlining the process for bulk production.

Natural Fibers

Sublimation printing is material-specific, working best on polyester and polyester-coated substrates. Natural fibers like cotton do not bond well with sublimation inks.

6.1 Suitable Fabrics:

• 100% polyester
• Poly blends (minimum 60% polyester for decent results)
• Performance fabrics (sportswear)

6.2 Non-Fabric Surfaces:

• Ceramic (mugs, plates)
• Metal (photo panels, license plates)
• Plastic (phone covers, ID cards)
• Wood (coated only)

6.3 Unsuitable Materials:

• 100% cotton (ink won’t bind)
• Non-coated surfaces (ink won’t transfer)

Process

Sublimation printing may seem technical at first, but with the right equipment and a structured approach, it becomes a seamless process. Here's a detailed walkthrough of each step involved:

7.1 Design Creation

Start by creating your artwork using graphic design software such as Adobe Photoshop, Illustrator, or CorelDRAW. Make sure to:

• Set color mode to CMYK
• Use high-resolution (300 DPI) images
• Mirror the design before printing
• Keep critical elements within safe margins

7.2 Printing the Design

Use a sublimation printer loaded with sublimation inks. Print your mirrored design onto sublimation paper. Ensure:

• Correct printer settings (ICC profiles)
• Avoid touching freshly printed sheets
• Use high-quality transfer paper for optimal ink release

7.3 Preparing the Substrate

• Pre-press the fabric or surface to remove moisture and wrinkles
• Ensure the substrate is polyester or coated
• Align your design carefully using heat-resistant tape

7.4 Heat Press Application

• Place the sublimation paper on the substrate
• Set the heat press temperature between 380°F to 400°F
• Apply pressure for 30 to 60 seconds
• Use protective Teflon sheets to avoid scorching

7.5 Post-Press Finishing

• Carefully remove the paper
• Let the substrate cool before handling
• Inspect for alignment, color accuracy, and ink coverage

13.4 ROI Consideration

Due to low running costs and high-quality output, sublimation printing offers a high return on investment for small businesses and large-scale manufacturers.

Sublimation Printing

Sublimation printing is often considered a more sustainable printing method compared to traditional techniques like screen printing or heat transfer. Here’s why:

✅ Waterless Process

Unlike conventional printing that requires large volumes of water, sublimation is a completely waterless process, helping conserve one of our most valuable natural resources.

✅ Minimal Waste

Sublimation uses precisely the amount of dye needed for each print. Since there are no screens, plates, or excess ink involved, there's very little material waste during production.

✅ Long-Lasting Prints

Because the dye is embedded directly into the fabric or substrate, sublimated prints don’t peel, fade, or crack over time. This extends the life of printed products, reducing the frequency of replacement and overall waste.

✅ Non-Toxic Inks

Most sublimation inks are non-toxic and environmentally friendly, especially when compared to solvent-based or plastisol inks used in traditional methods.

✅ Energy Efficiency

While sublimation does require heat, many modern sublimation printers and heat presses are energy-efficient, especially when printing in batches.

17.5 Inadequate Pre-Pressing

Failing to pre-press can trap moisture, affecting ink transfer

About Sublimation Printing

Q1: Can sublimation printing be done on dark fabrics? No. Sublimation works best on white or light-colored polyester substrates. Dark fabrics absorb the dyes, making the design invisible.

Q2: Is sublimation printing permanent? Yes. The dyes bond with the polyester fibers and become part of the fabric, ensuring durability.

Q3: How do I maintain my sublimation printer? Run print head cleanings regularly, use it frequently to avoid clogs, and store in a dust-free environment.

Q4: Can I use a regular inkjet printer for sublimation? Only certain inkjet printers (like some Epson EcoTank models) can be converted for sublimation with compatible inks.

Q5: What temperature is ideal for heat pressing? Typically 380°F to 400°F, but it depends on the substrate and transfer paper used.
