A layer or coat of material applied to paper or fabric; in printing, refers to the process of transferring an image.
From French couche (bed, layer), derived from Latin collocare (to place together), referring to layers placed one on top of another.
The printing technique called couching was revolutionary—artists discovered they could transfer delicate images from one surface to another by laying them in layers, creating a technique still used in papermaking and printmaking today.
