Abstract
The invention relates to a method for providing a coating lay for a label web (100), the method comprising arranging a substrate, applying a metered coating (121) in a contactless manner onto a surface of a coating roll (510), and transferring the coating (121) from the coating roll (510) onto the substrate (140) in a nip (515) thereby forming a coating layer onto the substrate, wherein, in the nip (515), the surface of the coating roll (510) is running in an opposite direction to a movement of the substrate (140), thereby obtaining the coating layer for a label web. The invention further relates to a system for providing a coating lay for a label web (100). The invention further relates to method for manufacturing a label web.
