The present disclosure describes a manufacturing method for seaming materials. The process may be suitable for manufacturing high performance projection screens using a number of methods including, but not limited to, conventional (convert-before-coating) methods, or convert-after-coating methods. An objective of the present disclosure is to identify a process which may substantially minimize distortion of the local surface normal in the vicinity of the join.
