Sublimation sheets (more accurately known as sublimation paper) are specialized papers used exclusively for dye-sublimation printing.
Understanding Sublimation Paper
Sublimation paper is a critical component of the dye-sublimation process. Here's a breakdown:
-
Specialized Coating: The key feature of sublimation paper is its special coating. This coating is designed to hold dye-sublimation inks on the surface without allowing them to soak into the paper fibers.
-
Transfer Mechanism: When heat and pressure are applied, the sublimation inks on the paper turn into a gas and transfer onto the intended substrate (like fabric, ceramic, or metal).
-
Purpose: It acts as a temporary carrier for sublimation inks. The inks are printed onto the paper, and then, through heat and pressure, are transferred to the final product.
Key Features
- Ink Retention: The coating prevents the ink from spreading, ensuring sharp and vibrant transfers.
- Heat Resistance: Designed to withstand the high temperatures involved in the sublimation process.
- Proper Release: Facilitates the release of the gaseous dye molecules from the paper onto the substrate.
In Simple Terms
Think of sublimation paper as a high-tech stencil. The ink is printed onto the stencil, and then heat is used to permanently imprint the ink onto the final product.
