什麼是裝裱

裝裱- (dry) mounting and laminating.
Usually would have a piece of UV protection transparent plastic sheet laminated on the face of a picture/photo (this is called " lamination "); and have a piece of card board, foam board, wooden board ..... etc sticked at the back (this is called " mounting "). With a 框架 or 相框 would call " framing ".
