Description

Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbegriff des ersten Patentanspruchs.The invention relates to a device according to the preamble of the first claim.

Um das immer wieder kehrende Auswerten von Farbmeßfeldern auf einem Druckbogen mittels Densitometer vereinfachen zu können, wird das Densitometer in X-Y-Richtung.an Schienen bewegbar gehaltert. Bei der ständigen Wiederholung einzelner Meßvorgänge bei gleichen Druckbögen scheidet ein Positionieren des Densitometers von Hand wegen der dabei auftretenden Ungenauigkeit aus.In order to simplify the recurring evaluation of color measurement fields on a printed sheet by means of a densitometer, the densitometer is held movably on rails in the X, Y direction. In the case of constant repetition of individual measurement processes with the same printed sheets, positioning the densitometer by hand is ruled out because of the inaccuracy that occurs.

Es ist z.B. zum Anfahren bestimmter Bereiche eines Druckbogens erforderlich, daß der Druckbogen auf seiner Unterlage in einer definierten Position liegt. Damit die bestimmten Bereichen immer die gleichen Koordinaten haben. Dies bedeutet, daß die Druckbögen immer exakt genau auf ihrer Unterlage positioniert und fixiert werden müßten, was aber nicht ohne weiteres realisierbar ist.It is e.g. To move to certain areas of a printing sheet, it is necessary that the printing sheet lies on its base in a defined position. So that the specific areas always have the same coordinates. This means that the printed sheets would always have to be positioned and fixed exactly on their base, but this is not easily possible.

Eine Möglichkeit der Positionierung der Druckbögen wäre z.B. die Verwendung von Anschlägen, an die die Druckbögen angelegt werden könnten. Da diese Anschläge gegenüber der Unterlage hervorstehen, wäre der Bereich um diese Anschläge für bestimmte Meßvorrichtungen nicht verfügbar, um dort Messungen durchzuführen.One way of positioning the printed sheets would be e.g. the use of stops on which the printed sheets could be placed. Since these stops protrude from the base, the area around these stops would not be available for certain measuring devices to carry out measurements there.

Aus der DE-OS 2 913 410 ist z.B. eine lichtelektrische Meßeinrichtung bekannt geworden, die die Lage einer Kante eines Bogens auf einer Fläche erfassen soll. Dabei soll die Lage der Bogenkante sehr genau ermittelt werden. Hierzu wird eine Reihe einer Mehrzahl dicht an dicht hintereinander liegender Lichtleitfasern angeordnet. Jede Lichtleitfaser wird mit einer Auswerteeinheit verbunden, welche ein Lichtsignal in ein elektrisches Signal umsetzt, das entsprechend weiter verarbeitet wird. Die freien planen Enden der Lichtleitfasern sind einer Lichtquelle zugekehrt und befinden sich in einem, Fenster der Bogenunterlage. Der Nachteil dieser Vorrichtung besteht jedoch darin, daß eine spezielle Lichtquelle oberhalb der Lichtleiter vorgesehen werden muß, die diesen Bereich für Meßzwecke unzugänglich macht. Außerdem muß der Bogen in diesem Bereich exakt plan aufliegen, damit eine genaue Lagefeststellung möglich ist.From DE-OS 2 913 410, for example, a photoelectric measuring device has become known which is intended to detect the position of an edge of a sheet on a surface. The position of the sheet edge should be determined very precisely. Here a number of a plurality of optical fibers lying close together are arranged. Each optical fiber is connected to an evaluation unit, which converts a light signal into an electrical signal, which is processed accordingly. The free flat ends of the optical fibers face a light source and are located in a window of the arch support. The disadvantage of this device, however, is that a special light source must be provided above the light guide, which makes this area inaccessible for measurement purposes. In addition, the sheet must lie exactly flat in this area so that an exact position determination is possible.

Weiter ist in der DE-OS 3 232 490 eine Vorrichtung zum Ermitteln und Auswerten von Farbmeßfeldern auf einen Druckbogen bekannt geworden. Ein willkürlich auf einer Bogenunterlage liegender Druckbogen wird mittels Bildsensoren lichtelektrisch erfaßt. Hierzu dient ein matrixartiger Bildsensor zur Lageerkennung zu einem festen Bezugspunkt C, oder zwei reihenartige Bildsensoren.Furthermore, a device for determining and evaluating color measurement fields on a printed sheet has become known in DE-OS 3 232 490. A printed sheet lying arbitrarily on a sheet base is photoelectrically detected by means of image sensors. For this purpose, a matrix-like image sensor is used for position detection at a fixed reference point C, or two row-like image sensors.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die densitometrische Messung und Auswertung von Druckbögen kostengünstig und schnell durchführen'zu können.Starting from this prior art, the invention is based on the object of being able to carry out the densitometric measurement and evaluation of printed sheets inexpensively and quickly.

Die Lösung der gestellten Aufgabe wird bei einer Vorrichtung der eingangs genannten Art durch das Kennzeichen des ersten Patentanspruchs erreicht.The object is achieved in a device of the type mentioned by the characterizing part of the first claim.

Die Lage der Druckbogen und die Lage der Farbmeßfelder des Druckbogens sind mit einem an sich bekannten und handelsüblichen Digitalisierungstableau mit einem an diesem angeschlossenen Griffel erfaßbar und in einem Speicher ablegbar. Die Verwendung eines handelsüblichen Digitalisierungstableaus verringert die Kosten der gesamten Meßvorrichtung beträchtlich. Die Handhabung mit dem Griffel ist während der Bedienung besonders einfach. Zuerst werden zwei oder drei Punkte zur Lageerkennung des Druckbogens auf dem Digitalisierungstableau abgetastet. Die Meßpunkte werden zu einem Nullpunkt des Digitalisierungstableaus zur relativen Lageerkennung umgerechnet und abgespeichert. Danach werden die einzelnen Farbmeßfelder auf dem Druckbogen mit dem Griffel abgetastet, so daß diese gespeicherten Werte das Densitometer zu beliebig oft wiederholbaren Meßvorgängen auf die richtige Positionen steuert.The position of the printed sheets and the position of the color measuring fields of the printed sheet are known and traded The usual digitizing table with a stylus connected to it can be recorded and stored in a memory. The use of a commercially available digitizing panel considerably reduces the cost of the entire measuring device. Handling with the stylus is particularly easy during operation. First, two or three points for the position detection of the printing sheet are scanned on the digitizing table. The measuring points are converted to a zero point of the digitizing table for relative position detection and saved. Then the individual color measuring fields on the printed sheet are scanned with the stylus, so that these stored values control the densitometer to the correct positions for measurements that can be repeated as often as desired.

Die Genauigkeit richtet sich hierbei nach der gewählten Rastergröße des Digitalisierungstableaus und liegt je nach dem mit welchen Frequenzzahlen bei üblichen Takten der Magnetostriktion gearbeitet wird, bei ca. 1/10 mm.The accuracy depends on the selected grid size of the digitizing table and is approx. 1/10 mm, depending on the frequency numbers used for standard magnetostriction cycles.

Die Auslösung des Meßvorganges wird durch Aufsetzen des Griffels auf die Meßpunkte des Druckbogens erreicht. Somit ist das Abtasten der ersten drei Lagekoordinaten sehr schnell zu erreichen. Je nach dem welche Meßwerte für Wiederholungsmessungen mittels des Densitometers ausgemessen werden soll, werden durch Kontakten mit dem Griffel die Koordinatenwerte der Farbmeßfelder im Speicher abgelegt.The measurement process is triggered by placing the stylus on the measuring points of the printed sheet. The scanning of the first three position coordinates can thus be achieved very quickly. Depending on which measurement values are to be measured for repeat measurements using the densitometer, the coordinate values of the color measurement fields are stored in the memory by contact with the stylus.

Auf diese besonders einfache Weise können die unterschiedlichsten Meßpunkte auch bei häufigen Änderungen der Meßpunkte durch Verschieben der Farbmeßfelder auf dem Druckbogen zügig und schnell aufgenommen werden.In this particularly simple manner, a wide variety of measuring points can be recorded quickly and quickly, even with frequent changes to the measuring points, by moving the color measuring fields on the printed sheet.

Um noch weitere kompliziertere Verknüpfungsfunktionen mittels des Digitalisierungstableaus durchführen zu können, ist die Verwendung eines Menüfeldes auf dem Digitalisierungstableau möglich. Werden zwei Meßpunkte mit dem Griffel auf dem Druckbogen abgetastet, so ist es möglich, die Dehnung in einer Richtung, hier speziell der Richtung in Papierfaserlauf zu messen.In order to be able to carry out even more complicated linking functions using the digitizing table, it is possible to use a menu field on the digitizing table. If two measuring points are scanned with the stylus on the printed sheet, it is possible to measure the elongation in one direction, especially the direction in the paper fiber run.

Werden drei Meßpunkte auf dem Druckbogen zur Lageerkennung des Druckbogens abgetastet, dann ist die Dehnung des Druckbogens in zwei Richtungen erfaßbar.If three measuring points are scanned on the printed sheet to identify the position of the printed sheet, the elongation of the printed sheet can be detected in two directions.

Weitere Vorteile und wesentliche Merkmale der Erfindung gehen aus den Unteransprüchen und der nachfolgenden Figurenbeschreibung in Verbindung mit den Ausführungsbeispielen hervor.Further advantages and essential features of the invention emerge from the subclaims and the following description of the figures in conjunction with the exemplary embodiments.

Fig. 1 zeigt ein Digitalisierungstableau 1, an dem mit einem Kontaktkabel 2.4 ein Griffel 2 angeschlossen ist. Auf dem Digitalisierungstableau 1 kann ein Druckbogen 3 mit Meßpunkten 2.1 - 2.3 und Farbmeßfeldern 14 - 14.2 willkürlich liegen. Je nach dem verbleibenden Platz zwischen den einzelnen Druckbildern des Druckfarbenauftrags sind die Farbmeßfelder 14 - 14.3 auf dem Druckbogen angeordnet.Fig. 1 shows a digitizing table 1, to which a stylus 2 is connected with a contact cable 2.4. A printed sheet 3 with measuring points 2.1-2.3 and color measuring fields 14-14.2 can lie arbitrarily on the digitizing table 1. Depending on the remaining space between the individual print images of the printing ink application, the color measuring fields 14 - 14.3 are arranged on the printing sheet.

Die Farbmeßfelder 14 - 14.3 haben an ihrem Anfang und Ende Markierungen für den Griffel 2.The color measuring fields 14 - 14.3 have markings for the stylus 2 at their beginning and end.

Liegt der Druckbogen 3 auf dem Digitalisierungstableau 1 wahllos auf, dann werden zuerst mit dem Griffel 2 die Meßpunkte 2.1 - 2.3 abgetastet, um die Lage des Druckbogens 3 auf dem Digitalisierungstableau 1 zu fixieren. Danach wird der Griffel 2 auf ein Menüfeld 9 getastet um die-Lage der Farbmeßfelder 14 - 14.3 ohne großen Zeitaufwand für spätere Wiederholungsmessungen durch Tasten abzuspeichern. In der linken unteren Ecke des Digitalisierungstableaus 1 befindet sich ein Einmeßelement 17 zum Eichen der Berechnungskoordinaten zwischen Griffel 2 und dem Digitalisierungstableau 1 und einem Densitometer 8.If the printed sheet 3 lies indiscriminately on the digitizing table 1, then the measuring points 2.1-2.3 are first scanned with the stylus 2 in order to fix the position of the printed sheet 3 on the digitizing table 1. The stylus 2 is then keyed onto a menu field 9 in order to save the position of the color measuring fields 14-14.3 without great expenditure of time for later repeat measurements by keys. In the lower left corner of the digitizing table 1 there is a measuring element 17 for calibrating the calculation coordinates between the stylus 2 and the digitizing table 1 and a densitometer 8.

Fig. 2 zeigt das Digitalisierungstableau 1 auf einem Koordinatentisch 1.1. Das Densitometer 8 ist auf einer Traverse 15 verschiebbar, wobei die Traverse 15 mit Lagern 12, 13 auf einer Führungsschiene 11 verfahrbar ist. Damit kann das Densitometer 8 alle Flächenbereiche des Digitalisierungstableaus 1 anfahren. Die Traverse 15 ist mit Endanschlägen 16 beidseitig an der Führungsschiene 11 gesichert. Auf einer einer Bedienungskonsole 18 ist eine Tastatur 10 zum Eingeben der unterschiedlichsten Daten vorgesehen. Die Dateneingabe erfolgt besonders schnell durch Tasten mit dem Griffel 2 auf den gewünschten Punkt. Zwischen den Koordinatenmeßtisch 1.1 und dem Digitalisierungstableau 1 ist ein Übergangsbereich 19. In der linken unteren Ecke befindet sich ein Einmeßelement 17 für die Nulleichung.2 shows the digitizing table 1 on a coordinate table 1.1. The densitometer 8 can be moved on a crossbar 15, the crossbar 15 with bearings 12, 13 being movable on a guide rail 11. The densitometer 8 can thus move to all areas of the digitizing table 1. The cross member 15 is secured with end stops 16 on both sides of the guide rail 11. On a An operating console 18 is provided with a keyboard 10 for entering a wide variety of data. Data is entered particularly quickly by pressing the stylus 2 at the desired point. Between the coordinate measuring table 1.1 and the digitizing table 1 there is a transition area 19. In the lower left corner there is a measuring element 17 for the zero adjustment.

In der Fig. 3 erkennt man die Dateneingabe der Meßpunkte 2.1 - 2.3 vom Griffel 2 zum Speicher 4. Die Koordinatenwerte der Farbmeßfelder 14 - 14.3 gelangen direkt zu einem Rechner 6. Vom Speicher 4 gelangen die Lagerwerte des Druckbogens 3 zum Rechner 6. Beide Datenwerte werden in einem Speicher 5 abgelegt, und können für die unterschiedlichsten Verwendungszwecke vom Speicher 5 abgerufen werden.3 shows the data input of the measuring points 2.1-2.3 from the stylus 2 to the memory 4. The coordinate values of the color measuring fields 14-14.3 go directly to a computer 6. The storage values of the printed sheet 3 go from the memory 4 to the computer 6. Both data values are stored in a memory 5 and can be called up from the memory 5 for a wide variety of uses.

In der Fig. 4 ist erkennbar, daß lediglich zur Bogenerfassung die Meßpunkte 2.1 - 2.3 in den Speicher 4 eingegeben werden. Die Lagedaten der Farbmeßfelder 14 - 14.3 werden vom Speicher 5 direkt an den Rechner 6 weitergegeben, um vom Rechner 6 mit beiden Positionsdaten das Densitometer 8 ansteuern zu können. Die Lagedaten der Farbmeßfelder 14 - 14.3 sind innerhalb eines Druckauftrags immer an den gleichen Positionen. Mit dem Griffel 2 sind somit lediglich nur zwei Meßpunkte 2.1- 2.3 auf dem Digitalisierungstableau 1 zur Lageerkennung des Druckbogens 3 abzutasten.In FIG. 4 it can be seen that the measurement points 2.1-2.3 are entered into the memory 4 only for sheet detection. The position data of the color measuring fields 14 - 14.3 are forwarded from the memory 5 directly to the computer 6 in order to be able to control the densitometer 8 from the computer 6 with both position data. The position data of the color measuring fields 14 - 14.3 are always in the same positions within a print job. With the stylus 2, only two measuring points 2.1-2.3 are thus scanned on the digitizing table 1 for position detection of the printed sheet 3.

Wenn die Dehnung des Druckbogens zusätzlich mit erfaßt werden soll, werden drei Meßpunkte 2.1 - 2.3 mit dem Griffel 2 abgetastet.If the elongation of the printed sheet is also to be recorded, three measuring points 2.1-2.3 are scanned with the stylus 2.

Die Fig. 5 zeigt das Schema, wenn mit dem Griffel 2 ein Funktionsfeld des Menüfeldes 9 auf dem Digitalisierungstableau 1 abgetastet wird. Die vorgegebenen Daten des Menüfeldes 9 gelangen zu einem Rechner 7, der diese Werte mit Werten aus dem Speicher 4 zusammen verarbeitet. Vom Rechner 7 gelangen die aufbereiteten Daten zu den jeweiligen benötigten Funktionen.FIG. 5 shows the diagram when a functional field of the menu field 9 is scanned on the digitizing table 1 with the stylus 2. The specified data from the menu field 9 is sent to a computer 7, which processes these values together with values from the memory 4. The processed data arrive at the respective required functions from the computer 7.
