Täyspäällystetty

Täyspäällystetty is a Finnish term used to describe a type of paper or board that has been coated on both sides. This coating is typically a layer of clay, calcium carbonate, or other mineral pigments mixed with a binder. The purpose of the coating is to improve the surface properties of the paper, such as its smoothness, gloss, and brightness.

The coating process for täyspäällystetty paper can involve several stages. First, the base paper is manufactured. Then, a coating mixture is applied to the surface, often using a blade coater or a roller coater. After the initial coating, the paper may undergo further processes like calendering, where it is passed through heated rollers to achieve a desired level of smoothness and gloss.

Täyspäällystetty paper is used in a wide variety of applications due to its enhanced printability and aesthetic qualities. It is commonly found in high-quality magazines, brochures, art books, packaging, and greeting cards. The smooth surface allows for sharper and more vibrant printing of images and text, making it a preferred choice for visual-heavy content. Different levels of gloss and matte finishes can be achieved depending on the specific coating formulation and finishing processes. The term distinguishes it from papers coated on only one side or uncoated papers.
