How to Sublimate on Cotton Fabrics (4 Proven Methods)

Sublimation printing is an excellent way to create bright, lasting prints, but there's a catch. It is well suited for polyester because the ink adheres to synthetic fibers when heated. Cotton does not have this special coating, so sublimation ink will not adhere.

Does that mean that you can't sublimate on cotton? Not at all! By using the right techniques, you’ll still be able to achieve amazing results. What you have to do is prepare a surface that will accept the ink by utilizing special pretreats or blending techniques.

Whether it's using sublimation sprays, polymer coatings, or clever shortcuts, there are proven ways of making sublimation on cotton feasible. In this guide, we're going to explore four effective methods to help you produce stunning, long-lasting prints on your favorite cotton fabrics!

Before you start sublimating on cotton, having the right materials and tools is key to getting the best results. Some items are essential for all sublimation methods, while others depend on the specific technique you choose.

No matter what your sublimation process is, there are certain tools that you simply can't do without. These tools ensure your sublimation process is trouble-free and your design is successfully transferred on to the material.

Here's what you’ll need:

A heat press is likely one of the most important pieces of equipment because it provides the ideal amount of heat and pressure needed to turn sublimation ink into gas and bond it to the material. Without constant heat and pressure, the transfer will not be as vibrant or long-lasting.

Next, you’ll need sublimation ink, which is specially formulated to turn into gas when exposed to heat.

Unlike regular ink, sublimation ink does not just sit on top of the fabric, it actually becomes part of the material when bonded with a sublimation-friendly surface. This is what gives sublimation prints their bright colors and durability. You can learn more about sublimation ink in this post below.

Sublimation paper helps hold your printed design prior to transferring it onto the fabric. This special paper is made to transport the sublimation ink and release it uniformly when heat is applied.

Using the incorrect type of paper may result in dull or uneven prints, so using high-quality sublimation paper is a must for the best results. Read more about sublimation here.

Finally, protective sheets such as parchment paper or Teflon sheets are necessary in keeping your heat press clean.

When sublimation ink turns into gas, it tends to seep out of the design area. A protective sheet prevents the ink from staining your heat press or transferring to other unwanted areas of the fabric. It also ensures an even distribution of heat, while the even heat allows for a professional and smooth print.

Different techniques require different materials. Here’s what you’ll need:

This process requires sublimation-compatible HTV, which is absorbed first by sublimation ink before being applied to cotton. A weeding tool is helpful when peeling off excess vinyl so that the design alone will transfer.

You will need rainbow glitter heat transfer vinyl which is sublimation-compatible. Print your design with sublimation ink and then transfer it to the previously applied glitter HTV on your cotton item. The glitter side allows the sublimation ink to adhere well, and a heat press ensures bright results.

All of these techniques bypass cotton's natural sublimation limitations.

You’ll need sublimation coating spray to create a polyester-like surface on cotton, allowing the ink to bond. A lint roller helps remove dust and fibers for a smooth, even transfer.

This process utilizes DTF (Direct-to-Film) transfer film, sublimation ink, and hot melt adhesive powder (also called hot glue powder). You create your design on the film with sublimation ink, cover it with the powder, and heat cure before transferring to cotton fabric with a heat press.

Since cotton lacks the polyester coating needed for regular sublimation, pre-treatment is helps create a surface able to bind with sublimation ink. Pre-treatment agents can be chosen depending on the wanted effect.

Here are the most popular ones and how they are utilized.

One of the easiest ways of getting cotton ready for sublimation is by using a sublimation coating spray. The spray leaves a thin, transparent coat on the material that mimics the properties of polyester, allowing the ink to adhere properly.

To use it, simply spray an even amount onto the surface of the cotton, let it dry, and then press the cloth with a heat press to set the coating.

This method works best for people who want the flexibility and smoothness of design without the added thickness of vinyl or fabric pieces. Just be aware that the result is reliant on the spray used and how well it is applied.

For a different process, other crafters use sublimation adhesive liquid or powder that sticks the sublimation ink onto cotton fibers. This is executed by brushing on the adhesive onto the material, placing the sublimation print on top of it, and then heat pressing.

The adhesive holds the ink in place, creating a lasting print. The final texture is raised a little, similar to heat transfer vinyl, but is a strong, lasting hold.

Polyester-treated pre-treatment solutions infiltrate into the cotton's fibers and allow for an open surface that accommodates sublimation.

Not like sprays that sit upon the fabric, these treatments will infiltrate and yield deeper, brighter, more long-lasting outcomes. They must be applied under caution and heat-set to ensure proper function but are a very good option for individuals seeking good-quality, professional finishes.

Each of these pre-treatment methods has its own benefits, so you'll use the correct one for your project requirements.

If you want bright, long-lasting sublimation prints on cotton, give the HTVRONT heat transfer vinyl (HTV) method a try. It entails using sublimation-compatible HTV, which will soak up sublimation ink and can then be heat-sealed onto cotton fabric.

Here’s the step by step process:

First, select an HTV that is sublimation-friendly; this type of vinyl contains a special surface that the sublimation ink can bond to.

Load the HTV sheet in your vinyl cutter and cut out the shape or size needed for your design. In case your design has a definite outline, cut the HTV to that outline. Once cutting is done, use a weeding tool and peel off excess vinyl, only the section where your design will be printed remains.

Pre-press your cotton fabric 5-10 seconds with a heat press before placing the HTV to dry and flatten out. Then, position the HTV (shiny side up) over the fabric where you want your design to appear.

Top it with a Teflon sheet or parchment paper and press 300-320°F (149-160°C) for 10-15 seconds. This causes the vinyl to adhere nicely to the fabric before sublimation. Let the vinyl cool for several seconds before carefully peeling away the carrier sheet slowly.

While your HTV is cooling, print your design in reverse on sublimation paper using sublimation ink. Once your print is done, place it face down on the HTV surface. Hold it in position with heat-resistant tape so that it doesn't shift around while transferring.

Adjust your heat press to 385-400°F (196-204°C) and apply medium pressure. Lay a Teflon sheet or parchment paper on top of the sublimation paper and press for 45-60 seconds.

The heat will activate the sublimation ink to adhere onto the HTV's surface. Remove the sublimation paper gently from squeezing, still warm. And voila! Your photo is now on the HTV, a bright color print on cotton fabric!

To make the design more long-lasting, again press the cloth for 10-15 seconds with a cover sheet over it. This step sets the ink into the cloth and prevents the material from being washed away. For optimal use, wash after 24 hours and wash with cold water using mild detergent.

Need super-sparkly, show-stopping sublimation prints on cotton? Use Rainbow Glitter HTV! This specialty vinyl is sublimation-friendly and adds a touch of magic sparkle to your designs while letting sublimation ink adhere beautifully.

Here's the step-by-step guide:

First off, setle for HTVRONT’s rainbow glitter heat transfer vinyl that is specifically marked as sublimation-friendly. This type has a special surface that absorbs sublimation ink while sparkling.

Cut to the shape corresponding with your design (or a square if your print doesn't need contour cutting) and put the vinyl in your cutting machine. Weed out the excess of the vinyl, and you are left with what you want to sublimate onto.

Pre-press your cotton fabric for 5-10 seconds to get rid of moisture and wrinkles. Then place the Rainbow Glitter HTV (shiny side up) on the fabric in the desired location.

Cover with a Teflon sheet or parchment paper, and press at 320–330°F (160–165°C) for 10–15 seconds using medium pressure. Let the HTV cool slightly before peeling off the carrier sheet.

While the HTV is warming up, print your design in reverse on sublimation paper with sublimation ink. When the vinyl has warmed and the carrier sheet removed, place the printed sublimation paper face down onto the glitter vinyl.

Hold the sublimation paper in place using heat-resistant tape so the design will not shift.

Set your heat press to 385–400°F (195–204°C) and use medium pressure. Place a Teflon sheet or parchment paper over everything and press for 45–60 seconds.

The heat vaporizes the sublimation ink and causes it to bond with the glittery surface of the HTV.

Peel off the sublimation paper while still warm. Your colorful design will now be glistening on top of the glitter vinyl!

For added durability, press one last time for 5–10 seconds with a protective sheet. Let it cool, and you’re all set.

Should you prefer to sublimate directly onto cotton with no extra vinyl or fabric cuts, using a polyester coating spray is a good choice. The procedure leaves only a very light coat of polyester on the fabric of the cotton so that it allows the ink used in sublimation to bond properly to it.

It is a cheap and simple solution for producing full-color prints but without sacrificing the natural softness of the garment.

Here’s a step-by-step guide to the process:

Begin by placing your cotton material on a flat, clean surface. Dust, lint, or loose fibers may cause problems with the sublimation process, so take out the lint roller and give the surface a good cleaning.

If the fabric is creased, press it lightly for a few seconds with a heat press to smooth it out. A flat and clean surface provides an even coat of coating spray and prevents final print defects.

Shake the sublimation coating spray well before using it. Holding the spray bottle about 6 to 8 inches away from the fabric, apply a light, even mist over the area where you’ll be printing your design. Avoid soaking the fabric, too much spray can make the material stiff and affect the ink absorption.

After application, allow the material to air dry for a few minutes, or apply a heat gun on low setting to hasten drying. Some sprays will need a brief heat press at low heat to completely cure the coating prior to printing, so read the instructions on your particular spray bottle.

While your fabric is drying, it’s time to print your design. Using a sublimation printer, print your design in when mirrored onto your sublimation paper.

This is important because the image will flip when transferred onto the fabric. Make sure your design is properly sized for your project and that you’re using high-quality sublimation ink for the best color results.

Once your coated fabric is dry, place the printed sublimation paper face down over the region of fabric where you want the design to appear.

Hold the edges in place with heat-resistant tape to prevent any movement during the heat press process. Any slight movement will cause the print to appear blurry or ghosted, so taping it down gives you clean, sharp details.

Preheat your heat press to 385-400°F (196-204°C) and medium-firm pressure. Place a Teflon sheet or parchment paper on top of the sublimation paper to avoid destroying your heat press. Press the fabric with a medium-firm pressure for about 45-60 seconds so that the ink is totally transferred to the polyester-coated surface.

When the timer runs out, carefully lift the heat press and peel off the sublimation paper while still warm. If all goes well, your picture should now be securely bonded to the coated material with vibrant, rich colors!

To ensure the design stays colorful and durable, we recommend pressing the fabric again for about 15 seconds with a protective sheet on top. This helps fix the ink totally and improve wash resistance.

Once cured, allow the fabric to cool down entirely before wearing or washing it. It is advisable to wait for at least 24 hours before the initial wash and to wash in cold water using mild detergent for improved durability.

Looking to create bright sublimation prints on 100% cotton? The DTF Film & Hot Glue Powder method is likely to be your new best thing. The technique allows sublimation ink to bond with cotton through the application of a proprietary adhesive film and powder mixture, no vinyl involved.

Here’s the step-by-step process:

Start by printing your sublimation design mirror (reversed) with sublimation ink onto the DTF film sheet, the side with a smooth printable surface.

Make sure the ink drops on the coated surface of the film, and print one layer only, no white ink necessary. Let the ink dry for a minute or two before continuing.

With the print newly wet, sprinkle on hot melt glue powder (also known as DTF adhesive powder) evenly over the printed side of the film.

Tilt the film so the powder is spread and covers all the ink evenly. Remove excess powder—only the printed sides should be lightly coated with glue powder.

Warm your heat press or oven to around 250–275°F (120–135°C). Instead of pressing, place the heat press platen just above the powder (don't touch!) for 2–3 minutes, or bake it in an oven.

The powder will melt and be glossy or slightly transparent, then it's done. Let the film cool a bit before proceeding to the next step.

Place your cotton shirt or material on the heat press and pre-press 5-10 seconds to remove moisture and wrinkles. Then place the DTF film (design side down) where you want the image.

Place parchment paper or a Teflon sheet over it and press at 350–375°F (175–190°C) for 20–30 seconds with medium to hard pressure.

Let the film cool down entirely before peeling off the peel—cold peel method. Peel off the DTF film slowly from the fabric to reveal a colorful design tightly stuck to the cotton.

To hold everything in place, cover the design with a parchment paper and press again at 350°F (175°C) for 10–15 seconds. This step adds strength and smoothes the texture.

With so many of these sublimation techniques for cotton, selecting the best one would seem daunting. That is why we simplified it in an easy comparison table so that you may quickly identify the differences regarding cost, longevity, ease of use, and compatibility with fabric.

Quick Takeaways:

Despite the best preparation, sublimation on cotton isn't always perfect. If you've ever removed your fabric from the heat press and discovered a fuzzy image, faded colors, or even yellowed fabric, don't panic, you're not alone!

Below are some common issues and simple solutions to ensure you achieve flawless results every time.

Nothing is more maddening than a sharp-looking design on paper that fades or blurs upon pressing. This normally results from improper temperature, pressure, or transfer time settings.

Solution:

Ever printed out a bright red design only to have it come out pale orange? That's due to the fact that sublimation inks sometimes don't print out exactly as they do on screen.

Solution:

If your white cotton material emerges yellowed or toasted, the temperature is too high.

Solution:

One of the most common concerns with sublimating cotton is that colors you observe under the press will sublimate away after some time.

Although cotton is not naturally inclined towards preserving sublimation ink like polyester, there are a few methods you can use to ensure your designs don’t lose their color and crispness.

While 100% cotton can be an issue, a simple way to extend the life of your sublimation prints is to use a cotton-polyester blend.

Polyester holds sublimation ink much better than cotton alone, so there is better adhesion and deeper results. A blend tends to produce stronger and longer prints than 100% cotton. If you prefer to use cotton, experiment with a material that contains at least 50% polyester for best results.

If you insist on sublimating directly on 100% cotton, then pre-treatment is necessary. A polyester coating spray is the answer here. The coating spray lays a layer on the cotton fabric like polyester, and hence makes the sublimation ink bond better.

Pre-treat your material so the ink will adhere better and remain from fading by ensuring the design is not sitting on the fibers but rather locked into them. Make sure to follow the instructions on how to apply it from the manufacturer for the best results.

Too much heat can actually degrade the sublimation inks or shift colors when applied to cotton. To avoid this, lower the heat and adjust the press time a bit.

The ideal temperature for sublimation on cotton is typically 375-385°F (190-195°C), but you'll be able to find the sweet spot by experimenting with your fabric and settings. If the heat is too high for too long, it can burn out the ink or cause unwanted coloration, so always keep an eye on your settings.

Once your sublimation picture is on the cotton fabric, washing and caring for it can be a major factor in how long it will last. To prevent the colors from fading and ensure they remain:

• Wash in cold water, heat degrades the ink, so don't hang in hot water.
• Turn the fabric inside out before washing to minimize friction and protect the design.
• Do not use bleach and harsh chemicals, these will bleach the ink over time.
• Dry by air or tumble low heat. The intense heat from the dryer will accelerate the aging of the ink.

Not all sublimation inks are the same, and low-quality inks can produce designs that will fade faster.

Always print with high-quality sublimation inks made specifically for printing on fabrics. These are longer-lasting and less likely to fade, so your designs will look vibrant for a lot longer, even after being washed multiple times. It's a little of an investment, but the payoff will be huge.

If you desire an extra layer of protection, some users apply a clear top coat of material or heat transfer adhesive after sublimation. 

This gives a protective covering that can increase the lifespan of your print and make it less likely to wash away and wear in general. Just be sure the product you're using is designed for application on fabric and is sublimation compatible.

Sublimating on cotton has been tested with various methods, and all have shown a range of durability and color fastness.

In Simply Sallie's test, products that were sprayed with a sublimation spray lasted about 85% of the original color after 30 washes, and HTV transfers remained up to almost 95% of their vibrancy. However, when sublimation was applied directly to cotton without any polyester backing, the results degraded quite a bit after just five washes.

TheMakersHQ and Lady Print Boss's studies also highlight practical experience. Their reports show that polyester blend fabric produces the most durable results, while others apply DTF (Direct-to-Film) transfers for a softer feel and better stretchability. 

These findings confirm that proper pre-treatment and transfer processes have a significant impact on influencing the durability and quality of sublimation prints on cotton.
