Inspection method for inspecting a sheet in a press, wherein the press comprises a punching unit which is suitable for receiving a sheet provided with a plurality of printed portions arranged in a regular manner according to a printing pattern and for cutting the sheet in dwell steps thereof, separating into several steps a plurality of printed discs, said method comprising: - providing abutting means (22, 23, 24) arranged upstream of the punching unit to receive the sheet to be cut and adjust the position of the sheet, - advancing in a first advancement direction the thus adjusted sheet to the punching unit to obtain the plurality of printed discs; - processing at least one acquired image of the sheet to detect an arrangement of the printing pattern in the sheet; - comparing the detected arrangement of the printing pattern with a nominal arrangement of the printing pattern to obtain a shift of the printing pattern in the sheet with respect to said nominal arrangement; characterised in that said method comprises: - acquiring at least one image of the sheet upstream of the abutting means (22, 23, 24), during advancement of the sheet in a second advancement direction; and in that said detecting said arrangement of the printing pattern comprises: - identifying a top edge, a bottom edge and a side working edge of the sheet and further identifying a top graphic mark, which is arranged in a top corner defined between the top edge and the side working edge, and a bottom graphic mark which is arranged in a bottom corner between the side working edge and the bottom edge; - calculating a longitudinal shift and a top side shift of the top graphic mark and a bottom side shift of the bottom graphic mark; and in that said adjusting the position of the sheet in said abutting means (22, 23, 24) comprises translating and/or rotating said sheet as a function of said longitudinal shift, and/or said top side shift and/or said bottom side shift to position said printing pattern in said nominal position so as to obtain in said punching unit printed discs in which each printed portion is arranged in a desired position. - providing abutting means (22, 23, 24) arranged upstream of the punching unit to receive the sheet to be cut and adjust the position of the sheet, - advancing in a first advancement direction the thus adjusted sheet to the punching unit to obtain the plurality of printed discs; - processing at least one acquired image of the sheet to detect an arrangement of the printing pattern in the sheet; - comparing the detected arrangement of the printing pattern with a nominal arrangement of the printing pattern to obtain a shift of the printing pattern in the sheet with respect to said nominal arrangement; characterised in that said method comprises: - acquiring at least one image of the sheet upstream of the abutting means (22, 23, 24), during advancement of the sheet in a second advancement direction; and in that said detecting said arrangement of the printing pattern comprises: - identifying a top edge, a bottom edge and a side working edge of the sheet and further identifying a top graphic mark, which is arranged in a top corner defined between the top edge and the side working edge, and a bottom graphic mark which is arranged in a bottom corner between the side working edge and the bottom edge; - calculating a longitudinal shift and a top side shift of the top graphic mark and a bottom side shift of the bottom graphic mark; - acquiring at least one image of the sheet upstream of the abutting means (22, 23, 24), during advancement of the sheet in a second advancement direction; and in that said detecting said arrangement of the printing pattern comprises: - identifying a top edge, a bottom edge and a side working edge of the sheet and further identifying a top graphic mark, which is arranged in a top corner defined between the top edge and the side working edge, and a bottom graphic mark which is arranged in a bottom corner between the side working edge and the bottom edge; - calculating a longitudinal shift and a top side shift of the top graphic mark and a bottom side shift of the bottom graphic mark; - identifying a top edge, a bottom edge and a side working edge of the sheet and further identifying a top graphic mark, which is arranged in a top corner defined between the top edge and the side working edge, and a bottom graphic mark which is arranged in a bottom corner between the side working edge and the bottom edge; - calculating a longitudinal shift and a top side shift of the top graphic mark and a bottom side shift of the bottom graphic mark;
