The invention relates to a printing device for printing surfaces of material panels, especially wood panels, with a multi-colour image, comprising: means for holding a material panel (30) in an oriented position; a printing unit (110) for printing a surface of the material panel (30), the printing unit (110) comprising a plurality of adjacently arranged printing heads (112), respectively for a plurality of colours, according to the width of the surface to be printed; and means for moving the printing unit (110) along an area of displacement over the surface of the material panel (30) held in place; said means for moving the printing unit (110) being designed to move the printing unit (110) at least over the surface of the material panel (30) at a regulated, pre-determined, constant work speed vDruck. The invention also relates to a method characterised by: the orientation of the material panel (30) such that the surface thereof is in a defined position and at a defined height; holding the material panel (30) in place; moving a printing unit (110) along a path of displacement over the surface of the material panel (30) held in place; and printing the surface of the material panel held in place (by means of the printing unit (110) ), the printing unit (110) comprising a plurality of adjacently arranged printing heads (12, 112), respectively for a plurality of colours, according to the width of the surface to be printed. The printing unit (110) is accelerated out of an idle position, according to a pre-defined acceleration profile, to a pre-determined working speed vDruck, before the printing unit passes over the material panel (30) along the path of displacement. The printing unit (110) is moved during the printing process at a constant speed vDruck and then brakes according to a pre-defined deceleration profile, until it (110) comes to a standstill and then moves back into the idle position.
