Abstract: Method and plasma treatment apparatus for treatment of a substrate surface (1) using an atmospheric pressure plasma. An atmospheric pressure plasma is provided in a treatment space (5) between a first electrode (2) and a second electrode (3). Furthermore, a substrate (1) and a mask web (7) in contact with the substrate (1) are provided. A plasma generating power is applied to the first and second electrode (2, 3) for treatment of surface areas of the substrate (1) exposed by the mask web (7), in which the substrate (1) and mask web (7) are moved synchronously through the treatment space (5).

Abstract: A method and apparatus for treatment of a substrate surface using an atmospheric pressure plasma is disclosed. The method comprises providing an atmospheric pressure plasma in a treatment space between a first electrode and a second electrode, providing a substrate in contact with the first electrode in the treatment space, and applying a plasma generating power to the first and second electrodes. The first electrode has a predefined structure of insulating areas and conductive areas for plasma treatment of surface areas of the substrate corresponding to the areas in contact with the conductive areas of the first electrode.

Abstract: A method of measuring a down-web coordinate is provided. A time-interval, elapsed since a detection of a position-indicating mark applied on a web, is related to a measured velocity. Upon detection of a position-indicating mark, the measured down-web coordinate is synchronised with the indicated down-web coordinate of said mark. The down-web coordinate can be measured in an ascending or a descending mode, depending on a detected roll-orientation information originated from said mark on said web. A selected lane pattern used for registration of the cross web position can be reversed automatically, depending on said roll-orientation information, originated from said mark on said web. A measured down-web starting position of a quality problem area on the web is marked by an ISO-hole.
