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.
Claims16
A method for inkjet printing on containers, comprising the steps of joining at least a first and a second subprint complementing each other in the printing direction so as to form a print image,
- wherein the first subprint is printed first starting from a connection area or up to a connection area and the second subprint is printed subsequently with a feed towards the connection area such that the first and second subprints interleavingly overlap in the connection area,
- wherein the first and second subprint do not adjoin one another in the connection area along a straight line extending transversely to the printing direction, but the connection area is formed in an intermeshing manner distributing image contents of the first and second subprint in a gear tooth configuration, and
- wherein the printing direction runs laterally about a main axis of the containers, and the first and second subprint interleavingly overlap in a circumferential direction of the containers.
A method for inkjet printing on containers, comprising the steps of joining at least a first and a second subprint complementing each other in the printing direction so as to form a print image,
- wherein the first subprint is printed first starting from a connection area or up to a connection area and the second subprint is printed subsequently with a feed towards the connection area such that the first and second subprints interleavingly overlap in the connection area,
- wherein the first and second subprint do not adjoin one another in the connection area along a straight line extending transversely to the printing direction, but the connection area is formed in at least one of an intermeshing and a mosaic-like manner distributing image contents of the first and second subprint,
- wherein the first and second subprint are printed by different print heads, and
- wherein one print head ejects a suitable number of subdroplets of a pixel in the connection area, and another print head ejects the rest of the subdroplets of the respective pixel.
