How to Sublimate on Dark Shirts or Black Colored 

Sublimation is a process of printing that uses heat and pressure to transfer ink from a paper to a fabric. It works best on light-colored and polyester-based materials, but it is possible to sublimate on dark shirts with some extra steps. In this comprehensive guide, we’ll explore the three best methods to achieve stunning results on How to Sublimate on Dark Shirts.

How to Sublimate on Dark Shirts

Understanding the Basics

Before diving into the methods, it’s crucial to understand the fundamentals of sublimation. This process relies on specially formulated inks and precise heat application to create a permanent, vibrant design on fabric.

Sublimation Ink Characteristics

Sublimation ink is unique in its ability to convert from a solid to a gas without going through a liquid form. This means it can penetrate and bond with the fibers of polyester fabrics, resulting in vivid, long-lasting prints.

Selecting the Right Materials

For successful sublimation on dark shirts, gather the following materials based on the chosen method:

Sublimation printer and ink compatible with dark fabrics

Sublimation paper

Clear heat transfer vinyl (HTV) or white glitter HTV

Cutting machine

Heat press

Protective paper or Teflon sheets

Bleach, water, spray bottle, stencil (for the bleach technique)

Here are some tips and tricks for sublimation on a black shirt:

Choose High-Quality Sublimation Paper: Opt for a high-quality sublimation paper that can transfer ink effectively without bleeding or smudging. A-SUB Sublimation Paper is a recommended choice for this purpose.

Use White Glitter Heat Transfer Vinyl as a Base Layer: To make your colors more vibrant and visible on dark shirts, consider using white glitter heat transfer vinyl as a base layer. White Glitter Heat Transfer Vinyl is a suitable product for enhancing the visibility of your sublimation design on dark fabrics. 

Secure Sublimation Paper with Spray Adhesive or Heat-Resistant Tape: To prevent the sublimation paper from shifting or moving during the heat press process, use a spray adhesive like Krylon Easy Tack Repositionable Adhesive Spray or heat-resistant tape to securely attach the paper to the heat transfer vinyl.

Use a Reliable Heat Press Machine: Invest in a high-quality heat press machine with precise temperature and pressure settings. Recommended settings for sublimation on dark shirts are typically around 400°F for about 60 seconds. 

Allow the Shirt to Cool Completely: After the heat press process, be patient and let the shirt cool down completely before peeling off the sublimation paper. This step ensures that the ink has fully transferred and bonded to the heat-transfer vinyl. Avoid touching the hot surface of the shirt or paper during this phase.

Maintenance and Care: You can treat your custom sublimated dark shirt like any other garment. It is safe to wash and dry it as usual but refrain from using bleach, as it can damage the design. Also, avoid ironing directly on the sublimated area, as excessive heat can affect the colors and design.

Choosing the Right Fabric for Sublimation on Dark Colors

The fabric composition is crucial for successful sublimation. Dark shirts made of polyester or polyester blends work best, as they allow the ink to fully bond with the fibers, resulting in a vibrant and durable print.

Here are the 3 Best Methods of how to do sublimation on black shirts

Method 1: Clear HTV Base Layer 

To begin, the process involves meticulous design preparation. Using professional design software, create and mirror the desired image. Adjust its size according to the dimensions of the shirt. Once satisfied, proceed to print the image onto sublimation paper utilizing a sublimation printer.

Next, employ a cutting machine to accurately cut out the image, making sure to leave a small margin around it. This ensures precision in the application process.

Before applying the sublimation, preheat the fabric using a heat press for a few seconds. This readies the material for the sublimation process.

Now comes the application phase. Position the sublimation paper face down on the dark shirt, ensuring that the clear HTV side is facing up. Take care to align it accurately, and then cover the setup with butcher or parchment paper.

Apply even pressure with the heat press for a duration of 10 seconds at 375°F. This step is crucial in facilitating the sublimation process.

Once the pressing is complete, allow the shirt to cool. After cooling, carefully peel off the sublimation paper along with the clear HTV layer.

Method 2: White Glitter HTV Base Layer 

As with the previous method, design preparation is crucial. Create and mirror your desired image using professional design software, and adjust the size according to the shirt.

Print the image onto sublimation paper using the sublimation printer. Then, employ a cutting machine to precisely cut out the image, leaving a small margin around it.

Apply the white glitter HTV onto the dark shirt for 15 seconds at 320°F. Peel off the carrier sheet while the HTV is still warm.

Position the sublimation paper over the white glitter HTV, ensuring that the printed side is facing down. Cover the arrangement with a butcher or parchment paper.

Apply even pressure with the heat press for a duration of 60 seconds at 400°F. This step is vital for successful sublimation.

After pressing, allow the shirt to cool. Once cooled, carefully peel off the sublimation paper.

Method 3: Bleach Technique 

As with the previous methods, design preparation is key. Create and mirror your desired image using professional design software and adjust its size according to the shirt.

Proceed to create a stencil of your image using vinyl or cardboard. This stencil will be used in the bleach application process.

Mix bleach and water in a spray bottle, maintaining a 1:1 ratio. Place the stencil on the dark shirt and spray bleach until a noticeable color change occurs.

Once the bleaching process is complete, remove the stencil and rinse off any excess bleach with cold water.

Dry the shirt using a hair dryer or an iron.

Position the sublimation paper over the bleached area, ensuring that the printed side is facing down. Cover with butcher or parchment paper.

Apply even pressure with the heat press for a duration of 60 seconds at 400°F.

After pressing, allow the shirt to cool. Once cooled, carefully peel off the sublimation paper. This concludes the bleach technique sublimation process.

By following these methods, you can achieve outstanding sublimation results on dark shirts, each offering a unique effect. Experiment with these techniques to create custom-designed shirts that stand out.

Frequently Asked Questions 

Q: Can I use cotton shirts for sublimation?

A: Sublimation works best on light-colored and polyester-based materials. Cotton shirts may not yield the same vibrant results.

Q: How can I ensure my design lasts longer?

A: Wash the shirt inside out in cold water and avoid harsh detergents or bleach. Air drying is recommended for longevity.

Q: What if my design looks faded after sublimation?

A: Ensure you’re using sublimation ink specifically designed for dark fabrics. Additionally, verify that your heat press settings are accurate.

Q: Can I sublimate on colored shirts other than black?

A: Yes, you can sublimate on other dark colors, but be aware that the base color will influence the final appearance of the design.

Q: Do I need special ventilation when sublimating?

A: While sublimation inks are generally safe, it’s advisable to work in a well-ventilated area to minimize inhalation of any fumes.

Q: Can I sublimate on already printed shirts?

A: It’s not recommended, as existing prints may interfere with the sublimation process and affect the final result.

Conclusion

Mastering the art of sublimating on dark shirts opens up a world of creative possibilities.
