An ink dosing device of a printing group, that includes a printing group cylinder which is configured as a plate cylinder, includes an inking unit. The ink dosing device has a number of physical zones which are arranged next to each other in a longitudinal direction. These physical zones can be individually adjusted by the use of dosing elements in order to individually adjust, section by section, the amount of ink that is applied. A control station is provided with a number of operator elements which are assigned to virtual zones of a printed page. These operator elements are usable to trigger the dosing elements. The segmentation of the virtual zones of the ink dosing device, in relation to the width of a printed page, differs in number and/or position of the zones of the ink dosing device across the width of the printed page from the segmentation of the zones in the control station in relation to the width of the printed page with respect to the number and/or position of the zones in the control station across the width of a printed page. At least two dosing elements are allocated using computing technology to at least one of the operator elements with respect to the relevance of the latter for the adjustment process following the selection of the operator element.
An ink metering device (04) of a printing couple (01) having a printing couple cylinder (02) embodied as a forme cylinder (02) and an inking unit, said ink metering device (04) having a first number (m) of physical ink zones (ZP,i) arranged side by side in the longitudinal direction of the printing couple and each having a first ink zone width, which first number of physical ink zones can each be adjusted individually using a first number of physical ink metering elements (Di), for the individual, section by section adjustment of a quantity of ink to be applied, to each of a number of print ink zones of a printed page of a print substrate, and further having a control station (07) which control station has a first number (n) of fixed width operator elements Bi assigned to a first number of virtual ink zones (ZV,j) of the printed page, said operator elements being usable for controlling said metering elements of said physical ink zones (Di), wherein a segmentation of the physical ink zones (ZP,i) of the ink metering device (04), based upon a width (bS) of the printed page, and with respect to at least one of a number and position of the physical ink zones (ZP,i) of the ink metering device (04) across the width (bS) of a printed page (S) is different from a segmentation of the virtual ink zones (ZV,i) on the control station (07), based upon the width of the printed page, with respect to at least one of a number and position of the virtual ink zones (ZV,j) on the control station (07) across the width (bS) of a printed page (S), and wherein at least two of said first number of physical ink metering elements (Di) are assigned to at least one of the operator elements assigned to said virtual ink zone (Bj), using a computing means, with respect to relevance in the positioning process and following the selection of said operator element assigned to said ink zone (Bi), said first number of said operator elements being a fixed number with a fixed width that is invariant with respect to a variable width of the printed page printed by the printing couple, said inking unit having an inking unit width greater than a maximum width of the print substrate capable of being printed by the printing couple.
A method for controlling an ink metering device of a printing couple having a printing couple cylinder and including:
