The installation for quality control of printed sheets (1) comprises means (8-13) for transferring said sheets, and cameras (2, 4, 6) for checking the print quality. The transfer means (8-13) are designed to transport the sheets in a plane and to allow the print quality of each of the faces of the sheet to be checked as well as a quality check using transparency to be carried out in succession and in a single pass. The means for checking each face are two cameras (2, 3) located on either side of said plane at two offset locations, the transfer means being designed to leave an open window at the side of each camera. A third camera (6) carries out the check using transparency.
