What Is Sublimation Digital Printing?

​​​

Sublimation digital printing is one of the most advanced and reliable methods for printing on polyester fabrics. It uses heat-sensitive sublimation inks that turn into gas when exposed to heat and permanently bond with the fabric’s fibers. Because the ink becomes part of the material—not just printed on top—the final image is vibrant, durable, and resistant to fading or cracking, even after multiple washes.

​

Simply put, inkjet sublimation printing involves using heat-activated sublimation dyes and a sublimation printer to transfer artwork onto polyester fabric or any polyester-coated surface.

This method is also known as transfer printing, heat transfer printing, or dye-sublimation printing.

​

Later in this guide, we’ll explore how digital sublimation printing can transform your textile business and open up exciting opportunities in custom fabric printing and digital textile design.

​What Do You Need for Sublimation Digital Printing?

​

Starting a sublimation digital printing business is simpler than you might think.

Your setup will depend on your production scale and the types of products you plan to create.
Here’s what every sublimation printing system requires:

​

1. Sublimation Printing Machine

2. Heat Transfer Equipment

3. Computer

4. RIP Software

5. Sublimation Paper (Heat Transfer Paper)

6. Sublimation Ink

7. Design Software

8. Polyester Fabric
   (And yes, don’t forget electricity! 😉)

 

Now, let’s break down each component.

​​

Sublimation Printing Machine

​

Your sublimation printing machine is the heart of your production setup.

Printers come in various sizes and configurations based on your product range and volume. For high-volume printing, choose industrial sublimation printers with open ink systems, which let you refill from bulk ink containers instead of cartridges.

This reduces printing costs and improves efficiency—ideal for commercial sublimation printing businesses.

​​

Sublimation Ink

​

Sublimation inks are formulated with vivid, heat-activated pigments that produce brilliant, long-lasting colors. The choice of ink can make or break your print quality.

​

While many brands provide inks matched to their printers, third-party inks are also available for compatible models. Always confirm printer and ink compatibility before use.

​

Most sublimation inks use the CMYK color model, but advanced systems include orange, pink, violet, neon yellow, neon green, and more for extended color range and higher vibrancy—ideal for fashion and sportswear printing.

​

Heat Transfer Paper (Sublimation Paper)

​

The quality of your sublimation transfer paper plays a crucial role in achieving sharp, consistent results.

These specially coated papers hold the ink until it’s ready to be transferred onto fabric or another surface.

​

Here’s what to look for when choosing sublimation paper:

​

• Ink compatibility: Match it with your printer’s ink type (water-based, solvent, or oil-based).

• High ink absorption: Ensures vibrant color and prevents ink bleed.

• Fast drying: Improves workflow and avoids smudging.

• Stable weight (90–140 GSM): Keeps paper flat and smooth during printing and transfer.

• Excellent ink release: Guarantees that the maximum amount of color transfers to your polyester fabric.

​

Avoid cutting corners on paper quality—premium heat transfer paper ensures smooth color transitions, superior saturation, and precise image detail.

​

If you print in advance, store your transfers in moisture-proof poly bags to maintain print quality and prevent humidity from affecting ink performance.

​

​

Heat Press Machine or Calender Heat Transfer System

​

So, you’ve printed your sublimation design onto transfer paper — now it’s time to bring that design to life! The next step in your sublimation digital printing process is transferring the image from paper to fabric using a heat press machine.

​

Why a Heat Press Is Essential

​

Printing is just the first stage — for sublimation printing on polyester fabric, you need heat and pressure to turn solid inks into gas and fuse them permanently with the fibers. This is what makes sublimation prints so durable, vivid, and wash-resistant.

​

For roll-to-roll production, you’ll need a calender heat transfer machine. These systems continuously feed both the printed transfer paper roll and the polyester fabric through heated rollers, applying consistent temperature and pressure to achieve perfect color transfer.

​

Choosing the Right Calender

​

Look for a professional calender system that’s fast, energy-efficient, and easy to operate — the ideal finishing partner for your digital sublimation printer.

​

To achieve the best results:

​

• Maintain a minimum temperature of 180°C for the sublimation process.

• Depending on the fabric type, set your heat press between 185°C and 200°C with a dwell time of 30–55 seconds.

• Thinner fabrics need less exposure time, while thicker materials may require a few extra seconds.

​

If your fabric feels stiff after pressing, reduce the exposure time slightly. Experiment with temperature and timing until you find the perfect settings for your specific polyester fabric.

​

A reliable large-format heat press machine can serve your business for decades and grow alongside your printing capacity — so it’s smart to invest in a high-quality, durable heat press that supports your long-term expansion.

​

Polyester Fabric for Sublimation Printing

​

When it comes to sublimation digital printing, one golden rule applies — only polyester fabrics can be sublimated.

​

Why? Because sublimation inks bond with polymer molecules, and polyester is rich in those polymers. That’s what allows the gasified ink to permanently embed into the fibers, creating vibrant, fade-proof colors.

​

Beyond fabrics, you can sublimate on thousands of polyester-coated products — from textiles and aluminum sheets to mugs, tiles, FRP boards, stainless steel items, and wooden décor.

​

When choosing a textile for sublimation, go for 100% polyester fabric that’s RFD (Ready for Dyeing/Printing) and pre-shrunk. This prevents shrinking and ensures consistent results when exposed to high heat.

​

Computer Setup for Sublimation Printing

​

Every sublimation printing setup needs a computer — it’s the control center for your design, production, and print management.

​

Here’s what your computer does:

​

1. Runs your design software (for artwork creation).

2. Runs your RIP software (for color management and print control).

3. Connects your printer and software seamlessly.

4. Lets you manage print size, quantity, and layout preview before production.

​

Whether you’re producing custom polyester fabrics, fashion textiles, or digital printed banners, a computer keeps your workflow smooth and consistent.

​

Design Software

​

Your design software is where creativity meets technology. It allows you to transform your imagination into printable digital art — whether it’s a surface pattern, fashion graphic, or custom textile print.

​

Professional tools like Adobe Photoshop or Illustrator are industry favorites because they offer advanced color management, ICC profile support, and high-resolution image control.

​

If your clients don’t provide ready-made designs, having your own textile design software is essential. It enables you to craft original graphics, patterns, and layouts for printing.

​

For best-quality sublimation results, make sure your digital artwork is at least 150 dpi, and export it in a format supported by your RIP software — typically TIFF, PSD, JPG, or PNG.

​

RIP Software for Sublimation Printing

​

RIP (Raster Image Processor) software is the backbone of every wide-format sublimation digital printing system. It’s a specialized program that controls color output, print precision, and ink usage.

​

RIP software acts as an advanced print driver, optimized for your printer model, sublimation ink set, transfer paper, and final fabric. It ensures your colors appear accurate, consistent, and true to your design.

​

Not all sublimation printers come with built-in RIP software, so it’s worth researching the right one for your setup. Popular industry options include Wasatch SoftRIP and neoStampa, both trusted by professional digital textile printers worldwide.

​

Some printer manufacturers bundle RIP software free with their machines, while others may offer it as an add-on — depending on your purchase agreement.

​

✅ Pro Tip: Investing in good RIP software can dramatically improve color accuracy, ink efficiency, and print quality — making your sublimation printing business more profitable and professional.

​

​

That wraps up everything you need to set up your sublimation digital printing system.

​

Now comes the exciting part — putting it all into action! When you’re just getting started, the sublimation printing process can feel like a mix of creativity and experimentation. Every print teaches you something new about color, heat, fabric, and technique.

​

Through our own journey in digital textile printing, we picked up some valuable insights — lessons that can save you time, ink, and fabric as you grow your sublimation printing business.

​

Here’s what we discovered along the way:

​

​

🔍 What to Check Before Sublimation Digital Printing

​

So, your sublimation printing setup is ready — printer, heat press, software, and fabrics. But before you start printing, it’s crucial to run through a few important checks.

​

To ensure your design transfers beautifully onto your product with wash-fast, scratch-resistant, and vibrant results, ask yourself three key questions:

​

1️⃣ Is the surface polyester-based?

Sublimation printing works exclusively with polyester because of its unique molecular structure — it bonds perfectly with sublimation ink gases during heat transfer.
Natural fibers like cotton, wool, nylon, leather, or vinyl won’t sublimate properly because they lack those bonding properties.

​

2️⃣ Can the product handle high heat and pressure?

The sublimation process requires temperatures of up to 400°F (about 200°C). So, make sure your product can withstand both the heat and the applied pressure without warping or discoloration.

​

3️⃣ Is the product light-colored?

Because sublimation uses dye-based technology, lighter colors — especially white or cream — yield the most accurate and vibrant results.

A true white polyester base delivers the full color gamut, while light-colored fabrics can achieve around 70–80% of your printer’s potential vibrancy.

​

Thankfully, there’s a massive range of ready-to-sublimate polyester products available today — from fabrics to mugs, tiles, metal sheets, and apparel.

​

​

⚙️ How Sublimation Digital Printing Works

​

Let’s break down the sublimation printing process into easy-to-follow steps:

​

1️⃣ Designing

​

Start by creating your artwork or repeat pattern using your design software. Make sure to size it correctly, mirror it if necessary (based on your RIP settings), and send it to your printer.

​

2️⃣ Printing

​

Use sublimation inks to print your mirrored design onto special sublimation transfer paper.

​

3️⃣ Heat Transfer Process

​

Now, it’s time for the magic. Place the printed transfer paper over your polyester fabric (print side down). Then, use your heat press or calender machine to apply heat and pressure.

​

Under the heat, the ink turns into gas and permanently bonds with the polyester fibers. Once you remove the paper, your design becomes part of the fabric — vibrant, smooth, and completely wash-resistant.

​

No drying, coating, or post-treatment is needed. The result? Long-lasting prints that don’t crack, peel, or fade — perfect for digital textile printing businesses.

​

​

🧵 Why Only Polyester Fabrics Work for Sublimation

​

Wondering why sublimation printing only works on polyester fabrics?

​

Polyester is a form of plastic, and when heated, its fibers open up slightly. The sublimation ink, which turns into gas during the process, seeps into these open fibers and becomes permanently embedded as the material cools.

​

This fusion between ink and fiber is what makes sublimation prints so durable, colorfast, and vibrant.

​

Natural materials like cotton or wool, however, can’t withstand the 180–200°C heat needed to activate sublimation dyes — they burn or scorch instead.

​

So, if you want professional-quality results, always choose 100% polyester RFD (Ready for Dyeing/Printing) fabric that’s pre-shrunk to avoid distortion.

​
