Abstract: A method and a direct-printing machine for printing on containers of different types of materials in a direct-printing process, wherein containers of a first type of material are conveyed by means of a conveyor and printed on, in several layers, with a plurality of printing units by means of direct-printing heads with a first basic ink compatible with the first type of material (102) and, on top of the first basic ink, with at least one colored ink. The first basic ink may be exchanged for a second basic ink, which is compatible with the second type of material, when a change to containers of a second type of material takes place, and the containers of the second type of material may then be printed on, in several layers, with the second basic ink (105) and, on top of the second basic ink, with the at least one colored ink.

Abstract: The invention relates to a method for printing objects, in particular containers, wherein the containers are transported along a specified transport path, and the outer surface of the containers is printed at least temporarily by means of at least one printing unit, wherein a controller controls the printing of the containers by means of the at least one printing unit on the basis of at least one printing parameter. According to the invention, at least one object to be printed is printed with at least one test marking in order to ascertain the printing parameter, and the object provided with the test marking is then inspected by means of at least one inspection device, wherein the printing parameter is derived from the result of the inspection.

Abstract: A container treatment machine for printing on containers, comprising a transport device configured in particular as a carousel and used for transporting a container flow along a transport track, and further comprising direct printing heads stationarily arranged on the transport track and used for applying a direct print to the container, characterized in that at least two of the direct printing heads are configured for applying the same printing ink to a container.

Abstract: An apparatus for printing onto containers is provided, including a transport device that transports the containers to be printed along a specified transport path, wherein the transport device includes a carrier and a plurality of holding devices provided on said carrier for holding the containers to be printed in such a way that the containers to be printed can be transported in an individualised manner, including a first printing unit that prints a specified image element onto the containers, including a second printing unit that is provided along the transport path of the containers after the first printing unit and prints a second image element onto the containers already printed with the first printing element.

Abstract: A method and a device for ink-jet printing onto containers is described, in which at least one container is rotated and/or transported along a curved path, and associated surface velocities of partially circumferential portions of a lateral container surface are measured, where the printing times and/or a rotational velocity of the containers associated with the partially circumferential and/or intermediately disposed portions are adapted to the surface velocities. Changes in the print advance rate caused by different surface velocities in front of print heads can thereby be compensated. This allows for uniform print resolution and seamless joining of partial prints.

Abstract: In a method and a device for inkjet printing on containers, at least a first and a second subprint complementing each other in the printing direction so as to form a print image are joined. The first subprint is printed starting from a connection area or up to a connection area. Subsequently, the second subprint is printed with a feed towards the connection area such that the first and second subprints interleavingly overlap in the connection area. This allows a joining of subprints with unobtrusive transitions even in the case of dimensional tolerances and complicated cross-sections of the respective container.

Abstract: Container handling machine for printing onto containers with a transport device optionally configured as a carousel for transporting said containers, with direct printing heads and with a cleaning device for cleaning the direct printing heads, the cleaning device including at least one cleaning unit for dispensing cleaning fluid to a direct printing head and a collection device for discharging spent cleaning fluid.

Abstract: A device for printing on containers, in particular non-rotationally symmetric containers, including at least one printing unit including at least one print head, a conveying system, which includes a plurality of container reception means arranged for rotation about axes of rotation and which is configured such that the container reception components circulate on a closed path and a print area of an outer surface of a container accommodated in a container reception components is movable past the print head, and at least one first drive adapted to rotate the container reception component, accommodating the container, about its axis of rotation by at least one open-loop and/or closed-loop control unit, the first drive being adapted to be variably controlled such that the print area is moved past the print head at a predetermined, substantially constant printing distance.
