Lämpösiirtokalvo, also known as heat transfer film, is a specialized material used to transfer images or designs onto various substrates using heat and pressure. This process, often referred to as heat transfer printing or sublimation printing, relies on the unique properties of the lämpösiirtokalvo to release and bond the applied ink to the target surface. The film typically consists of a base material, an ink layer containing the desired design, and a release coating that facilitates the transfer.

The application of lämpösiirtokalvo involves several key steps. First, the design is printed onto the film using specialized inks, often sublimation inks which are designed to turn into a gas when heated. The film is then precisely positioned onto the substrate, which can range from textiles and ceramics to plastics and metals. Next, a heat press machine applies controlled heat and pressure for a specific duration. Under these conditions, the ink sublimates, transitioning directly from a solid to a gas, and penetrates the surface of the substrate. As the film cools, the ink solidifies, becoming an integral part of the substrate's surface.

Lämpösiirtokalvo offers several advantages, including the ability to produce vibrant, durable, and high-resolution images. It is also versatile, suitable for a wide array of materials and applications, from custom apparel and promotional products to industrial labeling. The process is generally cost-effective for both small and large production runs, making it a popular choice for various industries. The final transferred image is often scratch-resistant and resistant to fading, ensuring longevity.
