How to Sublimate on Dark Colors and Cotton Shirts

Sublimation printing is a popular method for creating vibrant, high-quality designs for custom apparel. However, traditional sublimation works best on 100% polyester shirts and light-colored garments, leaving many wondering how to sublimate on dark colors and cotton shirts. In this guide, we’ll explore the best techniques to achieve high-quality sublimation prints on dark and cotton fabrics, including essential supplies like sublimation inks, transfers, and printers.

Can You Sublimate on Dark Colors and Cotton?

The short answer is yes, but not directly. Sublimation ink turns into a gas when heated, bonding with polyester fibers. Since cotton lacks these fibers and dark fabrics don’t allow the colors to show through, special methods are required. Without proper preparation, attempting to sublimate directly onto these fabrics will result in faded or washed-out designs. Fortunately, with advancements in printing technology, there are effective solutions to overcome these limitations. This is how to sublimate on dark colors and cotton fabrics.

Methods for Sublimating on Dark Colors and Cotton Shirts

1. How to Sublimate on Dark Shirts Using White Glitter HTV (Heat Transfer Vinyl)

One of the most effective ways to sublimate on dark colors is by using white glitter HTV as a base. The glitter particles contain polyester, allowing the sublimation ink to adhere and provide a vibrant, long-lasting print.

Steps:

1. Cut the White Glitter HTV: Use a vinyl cutter to cut out the shape of your design.
2. Heat Press the HTV: Apply the cut HTV onto the blank shirt using a heat press at around 320°F for 15-20 seconds.
3. Sublimate on Top: Print your sublimation design onto sublimation paper, then press it onto the HTV at 400°F for 60 seconds.

2. Sublimation on Cotton Shirts Using Sublimation Spray or Coating

Sublimation sprays add a polyester-like coating to cotton fabric, allowing the sublimation ink to bond.

Steps:

1. Apply Sublimation Spray: Evenly spray the area where you want your design.
2. Let It Dry: Allow the spray to dry completely before pressing.
3. Press the Sublimation Print: Heat press the design at 400°F for 60 seconds with medium pressure.

3. How to Sublimate on Cotton and Dark Fabrics with DTF (Direct to Film) Transfers

DTF printing is an excellent alternative to traditional sublimation on cotton and dark colors.

Steps:

1. Print Your Design: Use sublimation ink and a compatible DTF transfer sheet.
2. Apply Hot Melt Powder: Sprinkle the powder evenly over the print.
3. Cure the Design: Heat the design with a heat press for 2-3 minutes at 300°F.
4. Press Onto the Shirt: Heat press the transfer onto the wholesale shirt at 325°F for 15 seconds, then peel the film.

4. Sublimation on Dark Shirts with Flock HTV

Flock HTV is another alternative that allows sublimation onto dark shirts. It has a soft, velvety texture and a polyester component that holds sublimation ink well.

Steps:

1. Cut and Weed Flock HTV: Design and cut the flock HTV to match your desired print area.
2. Apply Flock HTV: Press it onto the shirt at 320°F for 15 seconds.
3. Sublimate on Top: Place your sublimation print on top and press at 400°F for 60 seconds.

5. How to Sublimate Using Sublimation Patches

Another workaround for sublimating on cotton or dark fabrics is by using sublimation patches. These are pre-coated polyester fabric pieces that you can sublimate on and then sew or heat press onto the garment.

Steps:

1. Sublimate the Patch: Print and press your design onto the patch.
2. Attach the Patch: Sew or use heat transfer adhesive to attach it to the shirt.

3. Experiment with Different Methods: Not all dark fabric solutions work the same way; try HTV, sprays, or DTF to see which provides the best results.
