lämpöpainatusta

Lämpöpainatusta, also known as heat pressing or thermal printing, is a printing technique that transfers an image or design onto a substrate using heat and pressure. This method is commonly employed for applying graphics, text, or logos onto various materials, most notably textiles like t-shirts, but also on other items such as mugs, plates, and metal.

The process typically involves a heat press machine, which consists of a heated upper platen and a lower pressure pad. A special transfer material, often a vinyl or paper coated with a heat-sensitive adhesive and the desired image, is placed on the substrate. The substrate and transfer material are then positioned within the heat press. The machine applies a controlled amount of heat and pressure for a specific duration. This heat activates the adhesive on the transfer material, causing it to bond with the substrate. Once the pressing cycle is complete, the transfer material is peeled away, leaving the image permanently affixed to the surface.

Different types of heat transfer materials exist, including heat transfer vinyl (HTV), sublimation paper, and plastisol transfers. HTV is a popular choice for its durability and versatility, available in a wide range of colors and finishes. Sublimation printing is ideal for creating vibrant, full-color designs on polyester-based materials, as the ink turns into a gas under heat and permeates the fabric. Plastisol transfers are pre-printed designs that are then heat-pressed onto garments. Lämpöpainatusta offers a cost-effective and relatively simple method for creating customized products, making it a popular choice for small businesses, hobbyists, and promotional item production.
