Claim:
1. A method for aligning the settings of print heads ( 212 ; 412 ; 701 ; 702 ; 703 ; 711 ; 712 ; 713 ; 721 ; 722 ; 723 ; 731 ; 732 ; 733 ) of at least one printing unit ( 200 ; 400 ) of a printing press ( 01 ) relative to one another, wherein in at least one first partial detection process, data regarding the settings of at least two print heads ( 212 ; 412 ; 701 ; 702 ; 711 ; 721 ; 722 ; 731 ) of a first subset ( 708 ) of print heads ( 212 ; 412 ; 701 ; 702 ; 703 ; 711 ; 712 ; 713 ; 721 ; 722 ; 723 ; 731 ; 732 ; 733 ) relative to one another are detected, and wherein in at least one second partial detection process, data regarding the settings of at least two print heads ( 212 ; 412 ; 703 ; 712 ; 713 ; 723 ; 732 ; 733 ) of a second subset ( 709 ) of print heads ( 212 ; 412 ; 701 ; 702 ; 703 ; 711 ; 712 ; 713 ; 721 ; 722 ; 723 ; 731 ; 732 ; 733 ), which do not belong to the first subset ( 708 ), relative to one another are detected, and wherein, proceeding from each print head ( 212 ; 412 ; 701 ; 702 ; 703 ; 711 ; 712 ; 713 ; 721 ; 722 ; 723 ; 731 ; 732 ; 733 ) of the at least one first subset ( 708 ), print heads ( 212 ; 412 ; 701 ; 702 ; 703 ; 711 ; 712 ; 713 ; 721 ; 722 ; 723 ; 731 ; 732 ; 733 ) of the at least one second subset ( 709 ) are arranged in only one direction with respect to the transverse direction (A), and/or in that, proceeding from each print head ( 212 ; 412 ; 701 ; 702 ; 703 ; 711 ; 712 ; 713 ; 721 ; 722 ; 723 ; 731 ; 732 ; 733 ) of the at least one second subset ( 709 ), print heads ( 212 ; 412 ; 701 ; 702 ; 703 ; 711 ; 712 ; 713 ; 721 ; 722 ; 723 ; 731 ; 732 ; 733 ) of the at least one first subset ( 708 ) are arranged in only one direction with respect to a transverse direction (A), and wherein in at least one full detection process, data regarding at least one setting of at least one first print head ( 212 ; 412 ; 701 ; 702 ; 711 ; 721 ; 722 ; 731 ) of the first subset ( 708 ) and at least one second print head ( 212 ; 412 ; 703 ; 712 ; 713 ; 723 ; 732 ; 733 ) of the second subset ( 709 ) relative to one another are detected, and wherein at least the at least one first partial detection process and the at least one second partial detection process are carried out at least partially simultaneously, and wherein at all times during the process, at most either the at least one full detection process is underway, or the at least one first partial detection process and/or the at least one second partial detection process is underway, and wherein in at least one adjustment process, the settings of at least two of the print heads ( 212 ; 412 ; 701 ; 702 ; 703 ; 711 ; 712 ; 713 ; 721 ; 722 ; 723 ; 731 ; 732 ; 733 ) of the at least one printing unit ( 200 ; 400 ) relative to one another are modified, and wherein the data acquired during the at least one first partial detection process and/or the data acquired during the at least one second partial detection process and/or the data acquired during the at least one full detection process are detected by means of at least two alignment sensors ( 740 ; 741 ) that can be moved, at least with respect to a transverse direction (A), and wherein at least two alignment sensors ( 740 ; 741 ) are moved, at least temporarily, independently of one another, at least in a transverse direction (A).
