Apparatus and method for acquiring multispectral images of one side of a printed sheet

摘要

An apparatus (1) for acquiring multispectral images of one side of a printed sheet (3) comprising a supporting surface (2) adapted to allow the placement of a sheet (3) whose printed image is to be acquired, a suction cylinder (6) adapted to make it possible to aspirate and lay without contact the sheet (3) that is made to pass thereon, grip means (4) adapted to make it possible to capture and immobilize one end of the sheet (3) without making contact with the image to be acquired, and a multispectral image acquisition system (5) arranged above the cylinder (6).
