Sublimation Transfers

What Are Sublimation Transfers: Understanding the Process and Applications

Sublimation transfers are a specialized method in the realm of printing and graphic design used to imprint designs onto various substrates. The process involves turning a solid directly into a gas without passing through the liquid stage, allowing for high-quality, long-lasting prints. Often used for creating custom apparel, ceramics, and other promotional items, this technique leverages dye-sublimation printers and specific types of ink and paper to achieve its final product.

The versatility of sublimation transfers is evident in the variety of materials that can be printed on, provided they are coated or composed of polyester. This is because sublimation ink can only bond with polyester fibers and coatings at high temperatures. The end result is a virtually permanent, full-color image that is embedded into the substrate surface, instead of merely laying on top. This leads to prints that are resistant to peeling and fading over time.

Key Takeaways

  • Sublimation transfers use heat to turn dye into gas, bonding it to polyester-coated items.
  • This printing method results in durable, high-quality images that resist fading.
  • Suitable for a range of materials, this technique requires specific equipment and inks.

Basics of Sublimation Transfers

Sublimation transfers involve a process where sublimation ink turns from a solid to a gas without becoming liquid. This happens under controlled heat and pressure conditions. Your target material typically is a polyester or polymer-coated item that can absorb the gas.

  • Temperature: Around 380–400°F
  • Time: Approximately 20–30 seconds
  • Pressure: Medium to high

First, you print your desired design using a sublimation printer and special sublimation ink onto sublimation paper. It’s crucial that your printer is loaded with sublimation ink, as regular ink won’t work.

When heat is applied via a heat press, the ink turns into a gas and bonds with the polymers in the substrate, creating a permanent, vibrant image that won’t fade or crack easily. Ensure the substrate’s surface is smooth and pre-treated if necessary.

  • Substrates: Commonly polyester fabrics or polymer-coated items
  • Printer type: Sublimation printer
