Abstract

A system (and related method) for coordinating electronic zonal control of a printing press to a hard copy image of the printed form. The system supports a hard copy image in register with an optical source which projects an optical mark onto the image. The optical mark is traversed to selected points on the image. The zonal control information is stored in electronic memory means and can be displayed on an electronic display. Neither the electronic display nor the electronic memory have means for storing the actual image pattern. The electronic display has means for displaying a cursor and traversing the cursor across the displayed zone-by-zone information. The system provides means for translating coordinate information from the optical mark projected onto the hard copy image and controlling the cursor position on the electric display so as to correlate image positions from the hard copy with control zone information in the electronic display.

Description

Die Erfindung betrifft eine Vorrichtung zum Auswerten von Druckvorlagen gemäß dem Oberbegriff von Anspruch 1.The invention relates to a device for evaluating printing originals according to the preamble of claim 1.

Aus der DE-3325006 A1 ist eine Anzeigeeinrichtung für Farbsteueranlagen für Druckmaschinen bekannt, bei der auf einem Bildschirmgerät Farbdichtewerte, Stell- und Toleranzwerte sowie Soll- und Ist-Werte dargestellt werden. Die anzuzeigenden Werte werden entweder über ein Farbsteuerpult (Tastatur) eingegeben oder durch an Farbzonen angeordnete Meßwertaufnehmer erfaßt. Diesen auf dem Bildschirm dargestellten werten wird das über eine Kamera von der Druckvorlage abgetastete Bild überlagert. Dadurch ist eine eindeutige Zuordnung von Anzeigewerten zum Druckbild möglich und der Drucker kann auf einen Blick Druckbild und Anzeigewerte erfassen. Nachteilig bei dieser bekannten Vorrichtung ist es, daß eine aufwendige Aufnahmeelektronik (Videokamera) erforderlich ist, um das komplette Druckbild zu erfassen, das anschließend auch noch durch eine weitere Elektronik, wie Bildumsetzer, Bildmischer, Zeichengenerator usw. umgesetzt werden muß.From DE-3325006 A1 a display device for color control systems for printing presses is known, in which color density values, setting and tolerance values as well as target and actual values are displayed on a display device.

Aus der US-PS 3930447 ist eine Anzeige- und Steuereinrichtung für eine Rotationsdruckmaschine bekannt, bei welcher der Drucker von einem Steuerpult aus eine oder mehrere Maschinendensitometer innerhalb der Maschine verfahren kann. An dem Steuerpult der Druckmaschine ist zur Anzeige von Meßwerten und sonstigen Stellwerten ein Bildschirm vorgesehen.From US-PS 3930447 a display and control device for a rotary printing press is known, in which the printer can move one or more machine densitometers within the machine from a control panel. A screen is provided on the control panel of the printing press to display measured values and other control values.

Aus der FR-2512950 A1 ist eine Meßvorrichtung zum Bestimmen von Farbkonzentrationen auf einem Druckbogen bekannt, bei der ein in einer Ebene fernsteuerbar positionierbares Densitometer an beliebige Bildstellen des Druckbildes verfahren werden kann um eben dort die Konzentration der aufgetragenen Druckfarben zu bestimmen. Diese vorbekannte Einrichtung weist ebenfalls Bildschirmgeräte zur Anzeige und manuelle Dateneingabevorrichtungen auf.From FR-2512950 A1 a measuring device for determining color concentrations on a printed sheet is known, in which a densitometer that can be positioned remotely in a plane can be moved to any desired image point on the printed image in order to determine the concentration of the applied printing inks there. These previously known device also has display devices for display and manual data input devices.

Aus der GB-2121357 A1 ist eine Steuervorrichtung für eine Druckmaschine bekannt, bei der ein berührungsempfindlicher Bildschirm Verwendung findet.A control device for a printing press is known from GB-2121357 A1, in which a touch-sensitive screen is used.

Die JP-5593119 A1 beschreibt eine Einrichtung mit einem Laser, mittels der ein Laserstrahl über zwei elektrisch bewegbare Spiegel derartig auf einen Schirm abgelenkt werden kann, so daß dort der Lichtstrahl an jeder beliebigen Position des Schirms eine Markierung projiziert.JP-5593119 A1 describes a device with a laser, by means of which a laser beam can be deflected onto a screen via two electrically movable mirrors, so that the light beam projects a marking there at any position on the screen.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung gemäß dem Oberbegriff von Anspruch 1 derartig zu erweitern, so daß in einfacher Weise Informationen von einer Druckvorlage und einem Datensichtgerät in individueller Weise miteinander zu verbinden sind.The object of the present invention is to expand a device according to the preamble of claim 1 such that information from a print template and a data display device can be connected to one another in an individual manner in a simple manner.

Gelöst wird diese Aufgabe durch die Anwendung der kennzeichnenden Merkmale von Anspruch 1. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved by applying the characterizing features of claim 1. Further developments of the invention result from the subclaims.

Des weiteren erfolgt die Erläuterung eines Ausführungsbeispiels der Erfindung in Verbindung mit der Zeichnung, die schematisch ein derartiges Ausführungsbeispiel darstellt.Furthermore, an embodiment of the invention is explained in connection with the drawing, which schematically represents such an embodiment.

Zweckmäßigerweise wird auf ein Steuerpult 1 eine Druckvorlage 2 aufgelegt, die ein Bild 3 trägt. Zur zonenweisen (Farb-) Steuerung sind an dem Steuerpult 1 zwei Tastenreihen vorgesehen, von denen lediglich eine (minus) Taste 5 und eine (plus) Taste 6 dargestellt sind.A print template 2 bearing an image 3 is expediently placed on a control panel 1. For zone (color) control two rows of buttons are provided on the control panel 1, of which only one (minus) button 5 and one (plus) button 6 are shown.

Auf einem Bildschirm 7 ist eine optische Markierung (8') vorzugsweise in Form eines Kreuzes, oder eines Balkens oder auch eines Punktes dargestellt. Der Bildschirm 7 ist Bestandteil eines an oder in der Nähe des Steuerpultes 1 angeordneten Bildschirmgerätes 9.An optical marking (8 ') is preferably shown on a screen 7 in the form of a cross, or a bar or a point. The screen 7 is part of a screen device 9 arranged on or in the vicinity of the control panel 1.

Wie die schematische Darstellung erkennen läßt, wird auch auf der Druckvorlage 2 eine vorzugsweise gleichartige optische Markierung 8 erzeugt, und zwar durch eine Lichtquelle 10. Vorzugsweise erzeugt die Lichtquelle 10 kohärentes Licht und besteht deshalb aus einem Laser. Wie angedeutet, ist die Lichtquelle 10 an einer Halterung 11 befestigt, die eine Verschwenkung in zwei Richtungen zulassen sollte, so daß die Lichtquelle 10 auf jeden beliebigen Punkt der Druckvorlage 2 gerichtet werden kann. Die Markierung 8 in Form eines Kreuzes kann also an einer beliebigen Stelle der Druckvorlage erzeugt werden.As can be seen from the schematic illustration, a preferably similar optical marking 8 is also produced on the printing template 2, specifically by a light source 10. The light source 10 preferably generates coherent light and therefore consists of a laser. As indicated, the light source 10 is attached to a bracket 11, which should allow pivoting in two directions, so that the light source 10 can be directed to any point of the artwork 2. The mark 8 in the form of a cross can therefore be generated at any point on the print template.

Die Ansteuerung bzw. die Zuführung der Verschwenkinformation erfolgt über eine Leitung 12, die mit einer Steuereinheit 13 verbunden ist. Letztere kann aus einem programmierbaren Rechner und ggf. weiteren elektronischen Bauteilen bestehen.The pivoting information is activated or supplied via a line 12 which is connected to a control unit 13. The latter can consist of a programmable computer and possibly other electronic components.

Gemäß der Erfindung weist die dargestellte Vorrichtung eine manuell betätigbare Zeigersteuerung 14 auf, beispielsweise in Form eines Rollballes, eines Joysticks, einer Maus, eines Graphiktabletts oder Cursortasten. Wesentlich ist es, daß mit der Zeigersteuerung 14 Koordinatensignale, üblicherweise X-Y Signale, erzeugt werden können, mit deren Hilfe über die Steuereinheit 13 eine Verschwenkung der Lichtquelle 10 im zweidimensionalen Koordinatensystem möglich ist, so daß die Lichtquelle 10 auf jeden beliebigen Punkt der Druckvorlage 2 gerichtet werden kann. Die Zeigersteuerung 14 ist über eine Leitung 15 mit der Steuereinheit 13 verbunden und ggf. können über eine Leitung 16 Steuer- oder Kontrollinformationen von der Steuereinheit 13 an die Zeigersteuerung 14 angelegt werden.According to the invention, the device shown has a manually operable pointer control 14, for example in the form of a rollerball, a joystick, a mouse, a graphics tablet or cursor keys. It is essential that the pointer control 14 can be used to generate coordinate signals, usually XY signals, with the aid of which a pivoting of the light source 10 in the two-dimensional coordinate system is possible via the control unit 13, so that the light source 10 is directed at any desired point on the original 2 can be. The pointer controller 14 is connected to the control unit 13 via a line 15 and, if necessary, control or control information can be provided via a line 16 the control unit 13 can be applied to the pointer control 14.

In der schematischen Darstellung ist die Lichtquelle 10 oberhalb des Steuerpultes 1 bzw. der Druckvorlage 2 angeordnet, so daß der optische Zeiger in Form der Markierung 8 im Auflichtverfahren erzeugt wird. Es ist jedoch auch möglich, insbesondere bei Druckvorlagen aus dünnen, also transparenten Papieren, eine Lichtquelle 17 auch in dem Steuerpult 1 bzw. hinter der Druckvorlage 2 anzuordnen, so daß die optische Markierung 8 im Durchlichtverfahren erzeugt wird. Der von der Lichtquelle 10 erzeugte Lichtstrahl 18 wird dann nicht von vorn, sondern von hinten auf die Druckvorlage projiziert.In the schematic illustration, the light source 10 is arranged above the control panel 1 or the print template 2, so that the optical pointer in the form of the marking 8 is generated by the incident light method. However, it is also possible, particularly in the case of printing originals made of thin, that is to say transparent, papers, to also arrange a light source 17 in the control panel 1 or behind the printing original 2, so that the optical marking 8 is generated by the transmitted light method. The light beam 18 generated by the light source 10 is then not projected onto the artwork from the front but from the rear.

Mit der vorbeschriebenen erfindungsgemäßen Vorrichtung kann durch entsprechende Bewegung der Zeigersteuerung 14 somit die Markierung 8 auf der Druckvorlage 2 auf beliebige Stellen gebracht werden. In besonders einfachen Fällen kann es auch ausreichend sein, die Markierung 8 nur in horizontaler Richtung zu verschieben, wodurch die Verschwenkung in der zweiten (Y) Richtung und die dafür erforderlichen Steuermittel entfallen.With the device according to the invention described above, the mark 8 on the print template 2 can thus be brought to any desired location by corresponding movement of the pointer control 14. In particularly simple cases, it may also be sufficient to move the marking 8 only in the horizontal direction, as a result of which the pivoting in the second (Y) direction and the control means required for this are eliminated.

Gleichzeitig mit der Markierung 8 auf der Druckvorlage 2 wird über die Steuereinheit 13 die Markierung 8′ auf dem Bildschirm 7 ebenfalls um das gleiche Maß und in der gleichen Richtung verschoben, jedoch üblicherweise mit einem reduzierten Maßstab, da der Bildschirm 7 kleiner als die Druckvorlage 2 ist. Auf dem Bildschirm 7 können, wie angedeutet, Informationen in Form von vertikalen Strichen dargestellt werden, die die Stellungen, beispielsweise von Farbschiebern oder der Farbmesserabschnitte in einzelnen Farbzonen interpretieren.Simultaneously with the mark 8 on the print template 2, the mark 8 'on the screen 7 is also shifted by the same amount and in the same direction via the control unit 13, but usually on a reduced scale, since the screen 7 is smaller than the print template 2 is. As indicated, information can be displayed on the screen 7 in the form of vertical lines which interpret the positions, for example of color slides or the color meter sections in individual color zones.

An einer Farbkastenwalze 19 sind schematisch diese Farbschieber 20 angedeutet. Sie werden jeweils über Farbzonenstellvorrichtungen 21 verstellt, um den zonenweisen Farbbedarf zu regulieren. Hierfür können die Farbzonenstellvorrichtungen 21 über jeweils eine Leitung 22 und einem Umschalter 23 her angesteuert werden, der über Leitungen 24 und 25 mit der Tastatur 5, 6 bzw. mit dem Bildschirmgerät 9 verbunden ist. Dadurch können die Farbschieber 20 wahlweise entweder von der Farbtastatur 6, 5 oder vom Bildschirmgerät her bzw. über die Steuereinheit 13 entsprechend angesteuert werden, wofür auch die bei 26 angedeutete Leitung bzw. Leitungen vorgesehen sind.These ink slides 20 are indicated schematically on an ink fountain roller 19. They are each adjusted via ink zone adjusting devices 21 in order to regulate the zone-by-zone ink requirement. For this purpose, the ink zone adjusting devices 21 can be controlled via a line 22 and a changeover switch 23, which via Lines 24 and 25 are connected to the keyboard 5, 6 and to the display device 9. As a result, the color slides 20 can be controlled either from the color keyboard 6, 5 or from the screen device or via the control unit 13, for which purpose the line or lines indicated at 26 are also provided.

Durch eine Bedienungsperson kann nun durch entsprechende Betätigung der Zeigersteuerung 14 die Markierung 8 auf der Druckvorlage 2 auf eine bestimmte Stelle gebracht werden und gleichzeitig wird auch die Markierung 8′ auf dem Bildschirm 7 auf die entsprechende gleiche Position verschoben. Dies kann erforderlich sein, wenn beispielsweise in einem bestimmten Bereich der Druckvorlage 2 mehr Farbe benötigt wird. Dieser Bereich wird dann, durch die optische Markierung 8′ auf dem Bildschirm 7 definiert und die Bedienungsperson (der Drucker) kann in diesem Bereich entweder über eine Tastatur oder über einen berührungsempfindlichen Bildschirm direkt die jeweilige Farbzonenstellvorrichtung aktivieren, um den gewünschten Farb- oder Feuchtmittelbedarf einzustellen. Es versteht sich, daß der Umschalter 23 entsprechend zuvor umgelegt werden muß.An operator can now bring the mark 8 on the print template 2 to a specific location by corresponding actuation of the pointer control 14 and at the same time the mark 8 'on the screen 7 is shifted to the corresponding same position. This may be necessary if, for example, more color is required in a certain area of the artwork 2. This area is then defined by the optical marking 8 'on the screen 7 and the operator (the printer) can activate the respective ink zone setting device in this area either via a keyboard or via a touch-sensitive screen in order to set the desired ink or dampening solution requirement . It is understood that the changeover switch 23 must be flipped accordingly beforehand.

Mit der erfindungsgemäßen Vorrichtung ist eine Positionsübertragung von einem Original, beispielsweise einer Druckvorlage, auf ein abstraktes Modell, beispielsweise auf einem Datensichtgerät, und umgekehrt möglich. Das übergeordnete Prinzip der Erfindung besteht somit darin, daß mit Hilfe einer Eingabeeinheit, z.B. der Zeigersteuerung 14, eine Markierung 8 auf der Druckvorlage 2 bewegt wird. Die aktuelle Position der Markierung 8 wird über eine Steuereinheit 13 übertragen und kann auf einem Bildschirm 7 sichtbar gemacht werden. Dadurch lassen sich in einfacher Weise beliebige Positionen von dem Original auf Graphiken von Datensichtgeräten und umgekehrt übertragen.With the device according to the invention, a position transfer from an original, for example a print template, to an abstract model, for example on a data display device, and vice versa, is possible. The overriding principle of the invention is therefore that with the aid of an input unit, e.g. the pointer control 14, a marker 8 is moved on the print template 2. The current position of the marker 8 is transmitted via a control unit 13 and can be made visible on a screen 7. As a result, any positions can be transferred in a simple manner from the original to graphics from visual display devices and vice versa.

Im folgenden werden zwei weitere vorteilhafte Ausführungsformen beschrieben, wobei hierfür die Steuereinheit 13 mit einem Speicher 27 ausgestattet ist. In dem Speicher 27 können Einstellinformationen für den Lichtstrahl 18 bzw. für die Lichtquelle 10 gespeichert sein und zwar vorzugsweise X-Y-Einstellwerte, mit deren Hilfe die Lichtquelle 10 bzw. der Lichtstrahl 18 auf jeden Punkt eines Druckexemplars bzw. einer Druckvorlage 2 gelenkt werden kann. Mit diesen abgespeicherten Strahlauslenkkoordinaten ist in vorteilhafter Weise eine Benutzerführung, beispielsweise für den Drucker, möglich, und zwar in der Art, daß der Lichtstrahl 18 nacheinander auf bestimmte Positionen der Druckvorlage 2 gerichtet wird. Diese Positionen können z.B. Meßstellen oder Meßpunkte darstellen, an denen der Drucker mit Hilfe eines Handdensitometers Farbmeßwerte aufnimmt, um diese über eine entsprechende Steuerung zum individuellen Einstellen der Farbschieber 20 zu verwenden. Somit ergibt sich hier eine sogenannte halbautomatische Benutzerführung. Der Drucker kann von Meßpunkt zu Meßpunkt oder von Registermarke zu Registermarke oder von farbfreien Bereichen zu farbfreien Bereichen usw. geführt werden, wenn deren Positionen bzw. Koordinatenwerte in entsprechender Folge in dem Speicher 27 vorliegen.Two further advantageous embodiments are described below, the control unit 13 being equipped with a memory 27 for this purpose. Setting information can be stored in the memory 27 be stored for the light beam 18 or for the light source 10, specifically preferably XY setting values, with the aid of which the light source 10 or the light beam 18 can be directed to any point of a printed copy or a print template 2. With these stored beam deflection coordinates, user guidance, for example for the printer, is advantageously possible, in such a way that the light beam 18 is successively directed to specific positions of the original 2. These positions can represent, for example, measuring points or measuring points at which the printer records color measured values with the aid of a manual densitometer, in order to use them via a corresponding control for individually adjusting the color slides 20. This results in a so-called semi-automatic user guidance. The printer can be guided from measuring point to measuring point or from register mark to register mark or from color-free areas to color-free areas etc. if their positions or coordinate values are present in the memory 27 in a corresponding sequence.

Eine weitere vorteilhafte Ausbildung bzw. Realisierung des erfindungsgemäßen Konzepts besteht darin, daß die Vorrichtung zur Eingabe von Koordinaten verwendet wird. Dies kann manuell oder automatisch erfolgen. Hierbei wird die Lichtquelle 10 auf die einzugebenden bzw. abzuspeichernden Koordinaten, d.h. auf bestimmte Positionen auf der Druckvorlage 2 gerichtet. Durch ein Signal, beispielsweise durch eine Tastenbetätigung, werden die X- und Y-Werte der Position der Lichtquelle bzw. der Auslenkposition des Lichtstrahls 18 erfaßt und abgespeichert. Hiermit können vorzugsweise die Koordinaten von Meßpunkten, von Meßmarken, von Registermarken, von farbfreien Bereichen, der X- und Y-Lage bei verschobenem Sujet (Lage des Nutzens auf der Druckplatte), von bildwichtigen Bereichen, von zu regelnden Bereichen, der Lage des Meßstreifens erfaßt werden und die von Bereichen, in denen Korrekturen der Repros erforderlich sind, sowie die von einem Anfangs- zu einem Endpunkt, um eine Längenerfassung zu ermöglichen (elektronischer Zollstock).Another advantageous embodiment or implementation of the concept according to the invention is that the device is used for entering coordinates. This can be done manually or automatically. Here, the light source 10 is based on the coordinates to be entered or stored, i.e. directed to specific positions on the artwork 2. The X and Y values of the position of the light source and the deflection position of the light beam 18 are detected and stored by a signal, for example by pressing a key. This can preferably be used to coordinate the measuring points, measuring marks, register marks, color-free areas, the X and Y position when the subject is shifted (position of use on the printing plate), image-important areas, areas to be controlled, the position of the measuring strip are recorded and those of areas in which corrections of the repros are necessary, as well as those from a start to an end point in order to enable a length measurement (electronic folding rule).

Die vorliegende Beschreibung läßt erkennen, daß das der Erfindung zugrundeliegende Konzept in vielfältiger Weise anwendbar ist.The present description shows that the concept on which the invention is based can be used in many ways.
