There is described a recto-verso printing press (100*) adapted to carry out simultaneous recto-verso printing of sheets, the printing press (100*) comprising a main printing group (5, 6, 15, 16, 25, 26) with first and second printing cylinders (5, 6) cooperating with one another to form a first printing nip between the first and second printing cylinders (5, 6) where first and second sides of sheets are simultaneously printed, the first printing cylinder (5) acting as a sheet conveying cylinder of the main printing group (5, 6, 15, 16, 25, 26). The printing press (100*) further comprises an additional printing group (7, 8, 17, 18, 27, 28) with third and fourth printing cylinders (7, 8) cooperating with one another to form a second printing nip between the third and fourth printing cylinders (7, 8) where the first and second sides of the sheets are simultaneously printed, the third printing cylinder (7) acting as a sheet conveying cylinder of the additional printing group (7, 8, 17, 18, 27, 28). The main printing group (5, 6, 15, 16, 25, 26) and the additional printing group (7, 8, 17, 18, 27, 28) are coupled to one another by means of an intermediate sheet conveying system comprising one or more sheet-transfer cylinders (10, 10', 10") interposed between the first and third printing cylinders (5, 7).
