Abstract

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.

Description

The invention relates to a paint metering device of a printing unit and to a method for controlling the ink metering device according to the features of claims 1 and 10, respectively.

By the DE 198 56 675 A1 a control device for controlling the printing of webs is known, wherein an analysis table is provided with a group of keys for individually controlling the opening and closing of ink fountain screws. The spacing of the keys corresponds to the physical distance of the respective fountain pen screws.

In the DE 42 16 440 B4 For example, an actuator below a sheet inspected by the printer is brought to a position corresponding to a print imagestrip to be corrected. An automatic detection system adjusts the ink fountain key of that zone and adjacent zones.

The DE 10 2004 018 743 A1 discloses a device for visualizing Farbdosierelementeinstellungen with a number corresponding to the number of Farbdosierelemente number of display devices.

By the DE 10 2004 022 700 B3 a Farbdosiereinrichtung is known, wherein a lying between two single pages panoramic color zone is assigned to a display screen both a display bar of the one print page, as well as a display bar of the other printed page. In order to avoid a conflicting points with one and the same control element, an average value for the two values desired by the operating personnel is formed and at the common actuating means considered.

The DE 10 2004 054 599 A1 discloses a form cylinder of a printing machine, which carries in the axial direction next to each other a plurality of printing plates.

The invention has the object of developing a Farbdosiereinrichtung a printing unit and a method for controlling the Farbdosiereinrichtung to the effect that a standardization for different machine widths is made possible.

The object is achieved by the features of claim 1 and 10, respectively.

The advantages that can be achieved with the invention are, in particular, that a cost-effective and standardisable solution for the inking units on newspaper printing presses is created. The hitherto high cost of conventional small series production of each ink fountain and the corresponding dosing specifically for a variety of machine or product formats can - be significantly reduced - at least in large areas or series of adjacent formats.

By adapting the displacements resulting from the unified metering elements to the operating conditions via calculation algorithms-in particular a computer-aided software solution-the operation can take place in the usual way without recognizable expenditure for the printer.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

An only schematically indicated printing unit 01 a printing press, in particular a newspaper printing unit 01 a newspaper printing machine, has at least one printing cylinder 02, z. B. forme cylinder 02 and a forme cylinder 02 inking inking unit with at least one roller 03 and one with the roller 03 for the purpose of coloring cooperating Farbdosiereinrichtung 04 on. By the printing unit 01 is a substrate 06, in particular a paper web 06, can be printed. Preferably, the printing unit 01 is formed as an offset printing unit for newspaper printing and has between form cylinder 02 and paper web 02 on a transfer cylinder, not shown. As a substrate in newspaper printing in contrast to the high-quality commercial or sheetfed offset printing uncoated or only slightly coated paper z. B. to 20 g / m ² , in particular up to at most 10 g / m ² printed. Between roller 03 and forme cylinder 02, one or more further rollers can be arranged depending on the type of inking unit and the roller z. B. as a ductor roller of a film inking unit, as a ductor roller of a pumping inking unit or as an anilox roller of an anilox or short inking unit. The forme cylinder 02 has on its circumference z.

A machine width M1, ie an effective width of the printing cylinder 02, is usually matched to the zuuckoende maximum printing material or web width and corresponds in newspaper printing z. B. substantially more than an integral multiple of a newspaper page width of the desired maximum product size or the width of the total on the forme cylinder 02 side by side arranged printing forms. Newsprint machines of different machine widths are thus designed and delivered by the machine manufacturer for different publishing houses or these printing presses.

) auf, mittels welcher jeweils in einer entsprechenden Zone Z_P,i (i = 1 .... m; mit m ∈

; Index P für "physikalisch") die Farbzufuhr steuerbar ist. Die eine Vielzahl von stellbaren Zonen Z_P,i aufweisende Farbdosiereinrichtung 04 kann in unterschiedlicher Weise ausgebildet sein. In den Figuren ist die Farbdosiereinrichtung 04 durch eine Vielzahl von als sog. Farbmesser D_i (Abstreifelemente) ausgebildeten Dosierelementen D_i ausgeführt, welche einzeln durch nicht dargestellte Antriebe in ihrem Abstand zur Mantelfläche der Walze 03 einstellbar sind. Je nach Spaltbreite dieses Abstandes verbleibt beim Abstreifen durch die Farbmesser D_i ein stärkerer oder weniger starker Farbfilm auf der zuvor mit einem Farbreservoir in Kontakt gebrachten Walzenmantelfläche. Um also eine individuelle Farbgebung über die Druckbreite bzw. den Farbkasten 04 gewährleisten zu können wird - z. B. mit Hilfe der nicht dargestellten Antriebe für die einzelnen Dosierelemente D_i - der Spalt zwischen Walze 03 und Dosierelement D_i je Zone Z_P,i eingestellt.In order to ensure an individual coloring over the entire printing width, the ink metering device 04 has in the axial direction next to each other a plurality of individually adjustable metering elements D _i (i = 1 .... m, with m ∈

), by means of which in each case in a corresponding zone Z _{P, i} (i = 1 .... m, with m ∈

; Index P for "physical") the ink feed is controllable. The color metering device 04 having a multiplicity of adjustable zones Z _{P, i} can be designed in different ways. In the figures, the ink metering device 04 is embodied by a multiplicity of metering elements D _i designed as so-called ink jet D _i (stripping elements), which are individually adjustable in their distance from the lateral surface of the roller 03 by drives not shown. Depending on the gap width of this distance remains when stripped by the ink knife D _i a stronger or less strong ink film on the previously brought into contact with a paint reservoir roll surface. So in order to ensure an individual color over the print width or the color box 04 - z. B. using the drives not shown for the individual metering D _i - the gap between roller 03 and metering D _i per zone Z _{P, i} set.

In a non-illustrated embodiment can as dosing D _i and a plurality of pumps D _i or a plurality of outlet openings D _i , each in the Zuführweg arranged, be provided with respect to the flow adjustable valves. In the following, the ink metering device 04 and the method for control will be explained by way of example on a so-called ink fountain 04 having a ink reservoir (ink fountain) and the plurality of ink blades D _i . The principle explained with reference to the colorimeter D _i is to be transferred to any other embodiment of dosing elements D _i forming physical zones Z _{P, i} .

) mit den entsprechenden virtuellen Zonen Z_V,j (j = 1 .... n; mit n ∈

) an einem Leitstand 07 wieder. In Fig. 1 sind je am Leitstand 07 aufzulegender Druckseite S eine Anzahl (z. B. virtuelle Zonenzahl =8) von z. B. als Taster ausgebildeten Bedienelementen B_j (bzw. Bedienelementpaaren, jeweils gekennzeichnet mit + und - ), vorhanden, mittels welchen der Drucker die Dosierelemente D_i und damit die Spalte an den physikalischen Zonen Z_P,i steuern kann. Durch drücken auf "+" wird der Farbfluss beispielsweise erhöht (Vergrößern des Spaltes oder Erhöhen der Pumpleistung), durch "-" z. B. erniedrigt (Verkleinern des Spaltes oder Senken der Pumpleistung). Die zahlenmäßige und räumliche Teiligkeit der virtuellen Zonen Z_V,j am Leitstand 07 entspricht hierbei (Fig. 1) der zahlenmäßigen und räumlichen Teiligkeit der physikalischen Zonen Z_P,i am Farbwerk. Bei Vorhandensein eines Voreinstellsystems 08 kann auch von der Produktdefinition in der Redaktion, über die Druckvorstufe bis hin zum Voreinstellsystem 08 die erforderlichen Flächendeckungen bzw. Farbdichten in die Positionierung dieser ganzzahligen Anzahl von Dosierelementen D_i bzw. Zonen Z_P,i umgerechnet werden. In Fig. 1 ist im unteren Bildbereich schematisch eine Zeitungsdoppelseite mit ihren Seitenbreiten b_S und den zugeordneten Bedienelementen B_j bzw. virtuellen Zonen Z_V,j mit den virtuellen Zonenbreiten b_V dargestellt. Hierbei entsprechen die für die am Pult aufgelegten Seiten geltenden virtuellen Zonenbreiten b_V den physikalischen Zonenbreite b_P am Farbwerk und die Anzahl der virtuellen Zonen Z_V,j je Druckseite S der Anzahl der wirksamen physikalischen Zonen Z_P,j. Eine wirksame, effektive Breite b_e der Farbdosiereinrichtung 04, d. h. der für die vorliegende Maschinenbreite M1; M2 benötigte Bereich mit Dosierelementen D_i entspricht im wesentlichen der Maschinenbreite M1; M2 bzw. der maximalen Bahnbreite.As mentioned above, in newspaper printing, ie in inking units of newspaper printing machines, different machine widths M1; M2 offered for different maximum product formats. Conventionally, for these different machine widths M1; M2 but then also in each case to this machine width M1; M2 specially adapted inking units used, wherein the division of the physical zones Z _{P, i} relative to a width b _S or page width b _S a print page S is always an integer (eg number = 8) is selected. So far, for example, for a newspaper printing machine with a wider product format, an inking unit with a certain number (eg eight) of wider metering elements D _i or zones Z _{P, i} , and for a newspaper printing machine with a narrower product format an inking unit with the same ( eg eight) or other integer number of metering elements D _i or zones Z _{P, i of} a smaller physical zone width b _P , so that in total an even number of zones Z _{P, m} corresponds to the print page width. The number of adjustable physical zones Z _{P, i} is usually reflected in the number of operating elements B _j (j = 1... N, with n ∈

) with the corresponding virtual zones Z _{V, j} (j = 1 .... n, with n ∈

) at a control station 07 again. In Fig. 1 are each printed on the control station 07 Druckseite S a number (eg, virtual zone number = 8) of z. B. trained as a button controls B _j (or control element pairs, each marked with + and -), available, by means of which the printer D _i and thus the column at the physical zones Z _{P, i} can control. For example, by pressing "+" the color flow is increased (increasing the gap or increasing the pump power), by "-" z. B. decreased (reducing the gap or lowering the Pump power). The numerical and spatial division of the virtual zones Z _{V, j} at the control station 07 corresponds to this ( Fig. 1 ) of the numerical and spatial division of the physical zones Z _{P, i} at the inking unit. In the presence of a presetting system 08, the required area coverage or color densities can also be converted into the positioning of this integer number of metering elements D _i or zones Z _{P, i} from the product definition in the editorial office, via the prepress stage to the presetting system 08. In Fig. 1 In the lower part of the picture, a newspaper double page with its lateral widths b _S and the associated operating elements B _j or virtual zones Z _{V, j} with the virtual zone widths b _{V is} shown schematically. In this case, the virtual zone widths b _V applicable to the pages placed on the console correspond to the physical zone width b _P at the inking unit and the number of virtual zones Z _{V, j} per printed page S to the number of effective physical zones Z _{P, j} . An effective, effective width b _{e of} the ink metering device 04, that is, for the present machine width M1; M2 required area with dosing D _i essentially corresponds to the machine width M1; M2 or the maximum web width.

A disadvantage of the machine-width-specific design of the ink metering device 04, in particular the metering D _i , is the high design complexity and the usual disadvantages known for "very small series".

The concept described below is based on the idea no longer for each specific machine width M1; M2 of a printing unit 01 in Zeitungsdruck specifically formed Farbdosiereinrichtungen 04, in particular the metering D _i to use, but for different machine widths M1; M2 - at least within certain limits - at least the same metering D _i , advantageously even the same Farbdosiereinrichtungen 04 to use.

In Fig. 2 schematically is a printing unit 01 and a control station 07 with a respect to the machine Fig. 1 smaller product format and a smaller machine width M2 shown. Here are on the forme cylinder 02, for example, several, compared to the machine Fig. 1 narrower printing forms arranged side by side. The contact surface at the control desk 07 and the width of the group of control elements B _j or the entirety of the virtual zones Z _{V, j} is also smaller or narrower according to the product. In Fig. 2 is on - for example, for a machine width M1 off Fig. 1 constructed - color box 04 shown, in which case the number of relevant at the control station 07 for the printed pages S virtual zones Z _{V, j} z. B. the same as that from the machine to Fig. 1 but with virtual zones Z _{V, j of} smaller zone width b _V. By contrast, the ink fountain 04 has metering elements D _i or physical zones Z _{P, i} with a zone width b _{P of} the physical zones Z _{P, i} or of the metering elements D that is different from the zone width b _{V of} the virtual zones Z _{V, j j} up. The virtual dividedness of the zones Z _{V, j} (at the control station 07 or the prepress) related to the printing page width (or the machine width M1, M2) is different from the physical parting of the zones Z related to the printing page width (or the machine width M1, M2) _{P, i} at the Farbdosiereinrichtung 04. While the virtual division in each case is an integer, a virtual, related to the print page width or effective width b _e division may also differ from an integer - z. In Fig. 2 about 6.3 per printed page S. Here, the quotient of the number of juxtaposed printed pages S taken into account and the number of associated zones Z _{V, j} , Z _{P, i} projected onto this width b _S (eg. in Fig. 2 : virtual division 8/1 or 16/2 etc. and physical division 6,3 / 1 or 12,6 / 2 etc.). The difference of divisions of the physical and virtual zones Z _{P, i} , Z _{V, j} can also exist in a different spatial position relative to the printed page S. In the present case, the differences in the division exist with regard to the number and position of the zones Z _{P, i} , Z _{V, j} .

Would the printer z. B. want to make a correction to the control element B ₃ for its virtual zone Z _{V, 3} and the operation as usual in newspaper printing without consideration of the different zone widths b _P ; b _V and / or situations on the Actuate the metering D ₃ act, it would be faulty (see Fig. 2 ). Order for different machine widths M1; M2 inking units of the same physical zone width b _P to be able to use is now a calculation algorithm A, in short: Algorithm, provided which the deviations between the virtual and physical zones Z _{V, J} , Z _{P, i} in number and / or position and / or width and converted accordingly.

The inking unit or the metering device 04 can, as in Fig. 2 shown more than the number of absolutely necessary dosing D _i have or only as many dosing D _m , as to fully cover the effective width b _e , ie the present machine width M2 required (in this case the Fig. 2 seven per side, six are not enough). In the former case, for different machine widths M1; M2 the same metering device 04 are used, in the second case for different widths of the metering device 04 at least the same metering D _i .

Corrects the printer using the example of Fig. 2 For example, by means of the controls B _3, the virtual, a pressure side strips associated zone Z _{V, 3} , so carried by the algorithm A such a conversion that the drive of the dosing D _{4 is} controlled. With regard to the size of the actuating signal, it is advantageous to take into account the size of the overlap or overlap between the position and width of the virtual and physical zones Z _{V, 3} and Z _{P, 4} . Since the physical zone Z _{P, 4} is wider here than the associated virtual zone Z _{V, 3} , the required real change of the gap width is smaller than the virtually requested change. Are like in Fig. 2 for the virtual zone Z _{V, 2} represented several physical zones Z _{P, i} (here Z _{P, 4} and Z _{P, 3} ) relevant, the conversion is carried out such that a plurality of metering D _i (here the two D ₄ and D ₃ ) - advantageously taking into account their coverage - positioned accordingly or their drives are controlled accordingly. The same principle of the conversion lies with the or an algorithm of a presetting system 08 (or the Pre-printing) on which the presetting values for the physical zones Z _{P, i} are to be formed from the otherwise standardized standardized integer-coordinated zones. However, it is advantageous if, in the presetting system 08 or in the prepress, the actual physical zones Z _{P, i} already are taken into account in the calculation of the presetting values from the required area coverage or color densities and stored there in the corresponding programs.

In another embodiment of the in Fig. 1 and 2 explained principle is in Fig. 3 a metering device 04 is shown, wherein the width b _{P of} the physical zones Z _{P, i} here is smaller than the width b _{V of} the virtual zones Z _{V, j} at the control station 07 or in the default settings of Vorereinstellsystems. That to the FIGS. 1 and 2 explained is here to apply in the same way. Virtual and physical (effective) parts of the zones Z _{V, j} , Z _{P, i} are again different from each other. The algorithm A, in turn, ensures that upon selection of a specific virtual zone Z _{V, j,} a corresponding transfer to the relevant metering element D _i or to the corresponding metering elements D _i (or their drive / drives) takes place. By way of example, the physical division here is an integer, in this case nine, but could also differ from an integer-based on the printing page width or the effective width b _{e of} the ink metering device 04. The virtual division (number of zones Z _{V, j} or controls B _j per print page S) is an integer and amounts to eight.

Will the printer for example in Fig. 3 by means of the controls B ₁₂ to correct the virtual, a pressure side strips associated zone Z _{V, 12} , so carried by the algorithm A such a conversion that the drive of the metering element D ₁₄ and the metering D _{15 is} controlled. The size of each required changes to the gap can then again the degree of overlap or overlap between at relative position and width b _V ; b _{P of} the relevant virtual and physical zones Z _{V, J} , Z _{P, i} into account.

In general, the ink metering device 04 has such a number m of metering elements D _i that the widths b _{P of} the zones in total are greater than or equal to the machine width M1; M2 or maximum web width. The width of the ink metering device 04 is then executed accordingly. Are like in the case of the examples Fig. 2 and 3 provided dosing elements D _i lying in edge regions of the ink metering 04 outside the effective width b _e , it can be provided in the algorithm A and or in the machine or pilot control that these metering elements D _{i are} generally controlled to closed gap. In one too Fig. 2 and Fig. 3 advantageous variant, it is provided that a varying total width of the ink metering 04 is allowed, but only in steps of then for different machine widths M1; M2 used same dosing D _i . Ie. the ink metering device 04 then has such a number m of metering elements D _i that the widths b _{P of} the zones Z _{P, i} in total are greater than or equal to the machine width M1; M2 is, however, a (m + 1) th metering element D _{m + 1} completely outside the effective width b _e or outside the projection of the machine width M1; M2 would lie.

The control station 07 is thus continued as usual with an integer, advantageously even number n of (virtual) zones Z _{V, j} or with the corresponding number m of controls B _j (eg n pairs of buttons B _j ), while the Paint metering 04 is formed with a different division of these zones Z _{P, i} standardized width b _P and possibly different number m. The format and / or number and / or zone-width-dependent shifts between virtual and physical zones Z _{V, J} , Z _{P, i} are converted and taken into account via the algorithm A-in particular computer-aided. For this purpose, corresponding computing means containing the algorithm are provided. The algorithm A may have a function among other things of the machine width M1 defined by the maximum web width; M2 and / or the number m of the physical zones Z _P , _i or the metering elements D _m and / or the number n of the virtual zones Z _{V, j} or the controls B _j and / or a width b _{P of} the physical zones Z _{P, i} be. The algorithm A contains fixed rules for the conversion or consideration of the shifts or the difference in number and / or position of the zones Z _{V, j} ; Z _{P, i} . Although these fixed rules and / or the above-mentioned input parameters (machine width, m, n, etc.) can be fixed, but can be stored by the operator changeable in the calculation means.

During presetting, the presettings of the dosing elements D _i can advantageously be related directly to the physical zone number m and physical zone width b _P with respect to the area coverage. However, it is also possible that the values for the presettings with respect to the area coverage initially related to the number of zones n at the control room 04, there converted via Algorithm A on the physical conditions in the above manner and the dosing D _i or their drives are acted upon.

For all examples ( Fig. 2 and 3 ) or modes in which differ in the printed page width division of physical and virtual zones Z _{P, i} , Z _{V, j} are one of the controls B _j on the computing means or the algorithm implemented there A more, z. B. assigned at least two dosing D _i or relevant to the job. In this case, one of the plurality of metering elements D _i can in turn be assigned to a plurality of, in particular two control elements B _j , due to the overlapping. The plurality of dosing elements D _i relevant to an operating element B _j are preferably positioned taking into consideration the degree of their covering with the operating element B _j .

For the above examples according to the Fig. 2 and 3 It is also significant that not only is a dosing element D _i located between two printed pages S assigned to two operating elements B _{j of} two adjacent printed pages S, but that by means of the algorithm A for a plurality of printed page S associated controls B _j and dosing elements D _i an adaptation to the Overlap occurs. It's on the Print side S thus related several zones with respect to their position shifted or different in terms of the number.
