A printing machine for printing a plurality of objects having an outer surface to be printed, the printing machine including: - a frame, and at least two treatment units (15, 17) and at least one printing unit attached on the frame, the printing unit comprising at least one inkjet printhead suitable for ejecting inkjets along a printing direction, and for the inkjets to be aligned along an alignment direction perpendicular to the printing direction, and - a turret mounted rotating relative to the frame around a rotation axis (Δ2), and comprising at least four object holders (61A, 61B, 61C, 61D) spaced regularly apart at 90° around the rotation axis (Δ2), and suitable for holding the objects and rotating the objects around four object-holder axes (D1-D4), the turret being movable successively between at least four positions relative to the frame, at least one of the object holders (61A, 61B, 61C, 61D) being across from the printing unit in each of the positions, while two others of the object holders (61A, 61B, 61C, 61D) are across from the treatment units (15, 17), wherein: - the object holder axes (D1-D4) are perpendicular to the rotation axis (Δ2), and - the printing machine includes a turret support on which the turret is mounted rotating around the rotation axis (Δ2), characterized in that: - an incline (β) of the turret support is adjustable around a pivot axis (Δ1) relative to the frame, the pivot axis (Δ1) being, on the one hand, perpendicular to the object holder axis of the object holder located across from the printing unit, and, on the other hand, coinciding with the object holder axes (D1, D3) of the other two object holders (61A, 61B, 61C, 61D) located across from the treatment units (15, 17). - a frame, and at least two treatment units (15, 17) and at least one printing unit attached on the frame, the printing unit comprising at least one inkjet printhead suitable for ejecting inkjets along a printing direction, and for the inkjets to be aligned along an alignment direction perpendicular to the printing direction, and - a turret mounted rotating relative to the frame around a rotation axis (Δ2), and comprising at least four object holders (61A, 61B, 61C, 61D) spaced regularly apart at 90° around the rotation axis (Δ2), and suitable for holding the objects and rotating the objects around four object-holder axes (D1-D4), the turret being movable successively between at least four positions relative to the frame, at least one of the object holders (61A, 61B, 61C, 61D) being across from the printing unit in each of the positions, while two others of the object holders (61A, 61B, 61C, 61D) are across from the treatment units (15, 17), - the object holder axes (D1-D4) are perpendicular to the rotation axis (Δ2), and - the printing machine includes a turret support on which the turret is mounted rotating around the rotation axis (Δ2), - an incline (β) of the turret support is adjustable around a pivot axis (Δ1) relative to the frame, the pivot axis (Δ1) being, on the one hand, perpendicular to the object holder axis of the object holder located across from the printing unit, and, on the other hand, coinciding with the object holder axes (D1, D3) of the other two object holders (61A, 61B, 61C, 61D) located across from the treatment units (15, 17).
