How to Sublimate on Dark Shirts

Sublimation is a process where solid dye transforms directly into a gas without turning into liquid, allowing it to bond with fabrics at the molecular level.

It is primarily designed for use on lighter, often polyester-based, substrates such that colors are hard to come by on darker materials due to the clear nature of the ink. But do not fret—every problem has a solution in one way or the other!

One common solution to this effect is Heat Transfer Vinyl (HTV). It is fairly light and allows for the application of sublimation ink, thereby enhancing the overall appearance of designs that are placed on dark-colored fabrics.

Another alternative includes sublimation spray coatings which facilitate the process of giving dark fabrics sublimation ink. You can even go high–tech with white toner printers that first lay down a white base under your design in order to enhance the colors used in the design.

Each method comes with its advantages and disadvantages, however, all of them enable you to design beautiful and attractive dark shirts. Now that we have finished discussing the basic techniques, let us focus on the equipment and materials you need for successful sublimation.

The types of tools that you choose will affect the output of your work, hence, it is good to purchase them wisely. Let’s break down some of the most important materials you'll need:

These are the essentials needed to transform even the simplest of dark shirts into a masterpiece. Most of the tools you will select will determine the quality of your outcome, so invest in good quality ones!

When it comes to designing for sublimation on dark shirts, choosing the right elements can make all the difference. Unlike lighter fabrics, dark shirts require bold, high-contrast designs to pop. Here’s what you need to keep in mind:

In the next section, we’ll guide you through the step-by-step process of sublimating dark shirts to achieve the best results.

This section will simplify and present how to sublimate on dark shirts in a series of steps, showing what materials to use. Here's what you need to have to achieve bright and durable prints on dark materials:

Kickstart the process by printing your sublimation design onto the sublimation paper. The higher the quality of the image, the better, so go ahead and play with colors. You could have one design printed in rainbow colors and another printed in one specific shade that pops on dark fabric.

After printing, place your sublimation paper on a cutting mat. Load it in your cutter and trim the excess areas, peeling off unneeded parts of it. Cut your HTVRONT Heat Transfer Vinyl - matte, rainbow glitter, or glossy clear - accordingly.

Weed the vinyl, or in other words, remove any unwanted portion. Get your black T-shirt ready by placing the weeded vinyl and sublimation paper on top.

Heat up your heat press machine to about 350 degrees Fahrenheit. Cover the T-shirt with the vinyl for about 10 seconds using a Teflon sheet to shield the image and ensure that the image as well is subjected to some pressure. Now, lift and let it cool for a while.

Place the sublimation paper centered over the vinyl, put a Teflon sheet on top of that, and press for 40 seconds. Make sure you press firmly onto the design to avoid shifting and misalignment.

The design won't show in highly saturated fabrics if you just have clear HTV. You can try using Glitter Vinyl or base it with white HTV underneath for more added brightness.

The temperature and time of the sublimation process depend on the type and kind of the Heat Transfer Vinyl HTV or material used and may vary within that range.

In most cases, especially when dealing with glitter HTV, place the heat press at a temperature of about 175°C for a duration of 15-20 seconds. Other heat–sensitive materials for that matter, could be placed at even 200°C but this time, a maximum of one minute 45 seconds is ideal. Very often when heat presses are used, a medium pressure is usually recommended.

To prevent distress such as peeling or partial cutting, look out for the user guide for the HTV. Also, ensure that your design is well-aligned prior to pressing. Temperature, pressure and time all play a vital role in making successful transfers and should be kept in good ratio.

When it comes to the sublimation of dark-colored shirts, some problems pop up frequently. These problems are just the results of poor application. Here are some of them along with sure ways to deal with them correctly:

Having these solutions in mind will help you achieve even better quality results when it comes to sublimating dark t-shirts.

Now that you know how to sublimate on dark shirts without bleach, and how exciting of a process it can be, please understand that safety is essential.

Always handle your heat press with care—ensure it's on a stable surface and never leave it unattended while in use. Wear heat-resistant gloves to avoid burns when handling hot materials.

Proper ventilation is crucial, as the sublimation process can release fumes that may irritate your lungs over time. When using cutting machines, be mindful of sharp tools like blades and weeding instruments. Following these safety tips, along with using high-quality materials, will ensure a successful and secure sublimation experience!
