lämpösiirtotulostus

Lämpösiirtotulostus, often translated as heat transfer printing or sublimation printing in English, is a printing technique used to transfer images and designs onto various substrates. The process typically involves printing a design onto a special heat-transfer paper using a sublimation ink. This inked paper is then placed onto the object to be printed, such as fabric, mugs, or metal plates, and subjected to heat and pressure from a heat press machine.

The heat causes the sublimation ink to turn into a gas, which then permeates the material of the substrate. As the material cools, the ink returns to a solid state, becoming permanently embedded within the substrate's fibers or surface. This results in a durable, vibrant, and high-resolution image that is resistant to fading and washing.

Lämpösiirtotulostus is widely used for custom apparel, promotional items, personalized gifts, and signage. Its ability to produce full-color, detailed graphics makes it a popular choice for both small-batch custom orders and larger production runs. The versatility of the method allows for printing on a wide range of materials, provided they can withstand the heat and pressure involved in the process. Specialized coatings are often applied to substrates like ceramics and metals to ensure proper ink adhesion.
