Abstract

Zwecks Abtastung der Einfärbung des Plattenzylinders sind in einem Bereich für jede Farbzone Kontrolleisten aufkopiert. Der Bereich kommt nicht in Berührung mit dem Gummituch des Gummizylinders und wird somit nicht vom Druckträger her verschmutzt. Während des Laufs der Druckmaschine werden diese Kontrolleisten durch ein traversierendes Densitometer abgetastet.For the purpose of scanning the coloring of the plate cylinder, control bars are printed out in an area for each color zone. The area does not come into contact with the blanket of the blanket cylinder and is therefore not contaminated by the print carrier. While the printing press is running, these checklists are scanned by a traversing densitometer.

Description

Die Erfindung betrifft einen Plattenzylinder für eine Rotations-Offsetdruckmaschine, an den ein Gummizylinder anstellbar ist, mit einer Vorrichtung zum zonenweisen Abtasten der Platteneinfärbung.The invention relates to a plate cylinder for a rotary offset printing machine, to which a rubber cylinder can be adjusted, with a device for zone-wise scanning of the plate inking.

Aus der französischen Patentschrift 1.519.883 ist ein Plattenzylinder der vorangehend spezifizierten Art bekannt. Hier wird die Einfärbung in den einzelnen Farbzonen mit Hilfe eines densitometrischen Meßgerätes während der Rotation des Plattenzylinders über den gesamten Umfang desselben ermittelt. Nachteilig bei einer solchen Messung der Farbdichte in den einzelnen Farbzonen ist es, daß diese infolge ihrer Berührung mit dem Gummizylinder im Laufe der Zeit verschmutzt werden, da von Druckträgern Papierstaub über den Gummizylinder auf den Plattenzylinder übertragen wird, wodurch es zu Meßfehlern kommen kann.A plate cylinder of the type specified above is known from French patent specification 1,519,883. Here the coloring in the individual color zones is determined with the help of a densitometric measuring device during the rotation of the plate cylinder over the entire circumference thereof. The disadvantage of such a measurement of the color density in the individual ink zones is that they become contaminated over time due to their contact with the rubber cylinder, since paper dust is transferred from the printing medium to the plate cylinder via the rubber cylinder, which can lead to measurement errors.

Aufgabe der Erfindung ist es, eine Messung der Farbdichte auf der aufgespannten Platte am Plattenzylinder zu ermöglichen, ohne daß eine Verschmutzung der Meßfelder während des Fortdruckes zu befürchten ist. Diese Aufgabe wird durch die Anwendung der Merkmale des Patentanspruchs 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus der Beschreibung in Verbindung mit den Zeichnungen. In diesen zeigen:

  • Fig.1 eine schematische Darstellung der Grubenbereiche eines Plattenzylinders und eines Gummizylinders und
  • Fig.2 eine Farbmeßvorrichtung an dem Plattenzylinder.
The object of the invention is to enable a measurement of the color density on the clamped plate on the plate cylinder without fear of contamination of the measuring fields during the production run. This object is achieved by using the features of patent claim 1. Further training of the Invention emerge from the subclaims and from the description in conjunction with the drawings. In these show:
  • 1 shows a schematic representation of the pit areas of a plate cylinder and a blanket cylinder
  • 2 shows a color measuring device on the plate cylinder.

Fig.1 zeigt schematisch jeweils den die Grube umfassenden Teil eines Plattenzylinders 1 und eines Gummizylinders 2. Auf dem Plattenzylinder 1 ist in üblicher Weise eine Platte 3 aufgespannt, während der Gummizylinder 2 ein Gummituch 4 trägt. Mit Hilfe einer Spannspindel 5 sind die Enden der Platte 3 und mit Hilfe der Spannspindeln 6 und 7 die Enden des Gummituches 4 fixierbar. Üblicherweise wird unter der Platte 3 eine Unterlage 8 und unter dem Gummituch 4 eine Unterlage 9 verwendet.1 schematically shows in each case the part of a plate cylinder 1 and a rubber cylinder 2 comprising the pit. A plate 3 is clamped on the plate cylinder 1 in a conventional manner, while the rubber cylinder 2 carries a rubber blanket 4. With the help of a clamping spindle 5, the ends of the plate 3 and with the help of the clamping spindles 6 and 7, the ends of the rubber blanket 4 can be fixed. A base 8 is usually used under the plate 3 and a base 9 under the rubber blanket 4.

Wie Fig.1 erkennen läßt, ist die Breite des Kanals 10 des Plattenzylinders 1 in Umfangsrichtung gesehen schmäler als die Grube 11 des Gummizylinders. Durch Übereinanderstellen der Druckendepositionen beider Zylinder 1,2 erhält der Druckanfang des Plattenzylinders 1 einen Vorlauf gegenüber jenem des Gummizylinders 2. Dadurch weist die Platte 3 eine Zone bzw. einen Bereich A auf, der zwar eingefärbt wird, aber mit dem Gummituch 4 nicht in Berührung kommt und somit dorthin keine Farbe abgeben kann. Wie eingangsbereits erwähnt, bringt dies u.a. den wesentlichen Vorteil, daß eine Verschmutzung des Bereiches A vom Druckträger her über das Gummituch 4 nicht zu befürchten ist.As can be seen in FIG. 1, the width of the channel 10 of the plate cylinder 1 is narrower in the circumferential direction than the pit 11 of the rubber cylinder. By stacking the printing end positions of the two cylinders 1, 2, the start of printing of the plate cylinder 1 is given a lead over that of the blanket cylinder 2. As a result, the plate 3 has a zone or region A which is colored, but does not come into contact with the blanket 4 comes and therefore can not give color there. As already mentioned at the outset, this has the essential advantage that contamination of area A from the print carrier over the blanket 4 is not to be feared.

Erfindungsgemäß wird vorzugsweise für jede Farbzone Z in diesem Bereich A bei der Herstellung der Platte 3 eine Kontrolleiste bzw. ein Meßfeld 12 (Fig.2) erzeugt, d.h. aufkopiert. Bekanntlich steht der Plattenzylinder 1 in ständiger Berührung mit mindestens einer Farbauftragswalze oder einem Farbzylinder (nicht gezeigt), der die Platte 3 kontinuierlich einfärbt.According to the invention, a control strip or a measuring field 12 (FIG. 2) is preferably generated for each color zone Z in this area A during the manufacture of the plate 3, i.e. copied on. As is known, the plate cylinder 1 is in constant contact with at least one inking roller or an ink cylinder (not shown), which continuously colors the plate 3.

Bei der erfindungsgemäßen Anordnung der Meßfelder 12 in dem Bereich A erfolgt somit auch eine stetige Einfärbung dieser Meßfelder 12 bei der Rotation des Plattenzylinders 1. Nachdem dieser Bereich A nicht in Berührung mit dem Gummituch 4 auf dem Gummizylinder 2 kommt, wird auch keine Farbe von den Meßfeldern 12 auf das Gummituch 4 übertragen. Es entsteht lediglich nach einer bestimmten Anlaufperiode durch Rückspaltung eine Übertragung von Farbe von dem Bereich A bzw. von den Meßfeldern 12 zur Farbauftragwalze und eine erneute Einfärbung derselben durch die Farbauftragwalze bis sich ein Gleichgewichtszustand eingestellt hat. Auf den Meßfeldern 12 in dem Bereich A entsteht somit eine Einfärbung, die repräsentativ für die Einfärbung des Bedruckstoffes in der jeweiligen Zone Z ist.In the arrangement of the measuring fields 12 in the area A according to the invention, there is therefore also a constant coloring of these measuring fields 12 during the rotation of the plate cylinder 1. After this area A does not come into contact with the rubber blanket 4 on the rubber cylinder 2, no color of the Transfer measuring fields 12 to the rubber blanket 4. Only after a certain start-up period by splitting back does a transfer of color from the area A or from the measuring fields 12 to the inking roller and a re-inking of the same by the inking roller occur until a state of equilibrium has been reached. A coloration which is representative of the coloration of the printing material in the respective zone Z thus arises on the measuring fields 12 in the area A.

Die erfindungsgemäß ausgebildete Kontrolleiste in Form von den einzelnen Farbzonen Z zugeordneten Meßfeldern 12 wird während des Maschinenbetriebes von einem Densitometer 13 stufenweise, d.h. nacheinander, abgetastet. Das Densitometer umfaßt eine Strahlungsquelle 14 und einen Sensor 15 und ist auf einer als Transportspindel dienenden Gewindespindel 16 angeordnet.The control bar designed in accordance with the invention in the form of measuring fields 12 assigned to the individual color zones Z is stepped by a densitometer 13 during machine operation, i.e. sequentially, sampled. The densitometer comprises a radiation source 14 and a sensor 15 and is arranged on a threaded spindle 16 serving as a transport spindle.

Letztere kann durch einen Elektromotor, vorzugsweise durch einen Schrittschaltmotor um ein definiertes Maß gedreht werden, so daß der Meßkopf 13 schrittweise von Farbzone zu Farbzone, d.h. von einem Meßfeld 12 zum nachfolgenden Meßfeld bewegt werden Beim Vorbeilaufen des Meßfeldes 12 an dem Meßkopf 13 erfolgt dessen Abtastung zwecks Ermittlung der Einfärbung, d.h. der in der jeweiligen Zone Z vorhandenen Farbdichte. Wird beispielsweise das Meßfeld 12 in der ersten Farbzone Z abgetastet, so kann während der nachfolgenden Drehung des Plattenzylinders 1 der Meßkopf 12 durch Aktivierung des Elektromotors 17 um einen Schritt nach rechts, d.h. zur zweiten Farbzone bewegt werden, so daß während der darauffolgenden Drehung des Plattenzylinders 1 das in der zweiten Farbzone Z befindliche Meßfeld 12 abgetastetwerden kann.The latter can be rotated by a defined amount by an electric motor, preferably by a stepping motor, so that the measuring head 13 is gradually moved from ink zone to ink zone, i.e. be moved from one measuring field 12 to the next measuring field. When the measuring field 12 passes the measuring head 13, it is scanned in order to determine the color, i.e. the color density present in the respective zone Z If, for example, the measuring field 12 is scanned in the first color zone Z, the measuring head 12 can be turned one step to the right, i.e. during the subsequent rotation of the plate cylinder 1, by activating the electric motor 17. be moved to the second color zone so that during the subsequent rotation of the plate cylinder 1 the measuring field 12 located in the second color zone Z can be scanned.

Fig.2 zeigt in schematischer Darstellung die Anordnung des Plattenzylinders 1 und des Gummizylinders 2 zwischen zwei Seitenwänden 18 üblicherweise, in denen auch die Gewindespindel 16 gelagert und der Elektromotor 17 angeflanscht sein kann.2 shows a schematic representation of the arrangement of the plate cylinder 1 and the rubber cylinder 2 between two side walls 18, in which the threaded spindle 16 can also be mounted and the electric motor 17 can be flanged.

Die in dem Meßkopf 13 ermittelten Werte gelangen über eine Leitung 19 in einen Rechner 20, der über eine Leitung 21 zeitgerecht den Elektromotor 17 ansteuert, um den Meßkopf 13 in der beschriebenen Weise von links nach rechts oder umgekehrt schrittweise weiterzubewegen.The values determined in the measuring head 13 reach a computer 20 via a line 19, which controls the electric motor 17 in a timely manner via a line 21 in order to move the measuring head 13 step by step in the manner described from left to right or vice versa.

In Abhängigkeit von den ermittelten, die Einfärbung repräsentierenden Werte steuert der Rechner 20 über eine Leitung 22 Farbzonenstellelemente 23 beispielsweise in Form von motorisch betätigbaren Farbzonenstellschrauben. Dadurch wird der Abstand eines Farbmessers 24 in der jeweiligen Farbzone Z entsprechend verändert und die von dem Farbkasten 25 mit Farbkastenwalze 26 abgegebene Farbe quantitativ entsprechend der erforderlichen Farbgebung nachgeregelt.Depending on the determined values representing the coloring, the computer 20 controls color zone control elements 23 via a line 22, for example in the form of motorized color zones set screws. As a result, the distance between an ink knife 24 in the respective ink zone Z is changed accordingly and the ink emitted by the ink fountain 25 with ink fountain roller 26 is readjusted quantitatively in accordance with the required coloring.

Wird beispielsweise im Meßkopf 13 in einer bestimmten Farbzone Z eine zu intensive Einfärbung festgestellt, so sorgt der Rechner 20 dafür, daß das entsprechende Farbzonenstellelement 23 das Farbmesser 24 in dieser Zone näher an die Farbkastenwalze 26 heranfährt, wodurch die Farbabgabe reduziert und dadurch die gewünschte Einfärbung in dieser Zone erreicht wird.If for example in the measuring head 13 a too intensive coloring is found in a certain ink zone Z, the computer 20 ensures that the corresponding ink zone adjusting element 23 moves the ink knife 24 closer to the ink fountain roller 26 in this zone, thereby reducing the ink delivery and thereby the desired inking is achieved in this zone.
