Description

Die Erfindung betrifft eine Anordnung zur Abmusterung eines Druckerzeugnisses nach dem Oberbegriff des Anspruches 1.The invention relates to an arrangement for sampling a printed product according to the preamble of claim 1.

Während des Anfahrvorganges, aber auch während des Fortdruckens ist es erforderlich, die Qualität des Druckerzeugnisses zu kontrollieren. Im ersten Fall möchte man möglichst schnell die gewünschte Bildqualität erzielen, d.h. Minimierung der Makulatur, und im zweiten Fall benötigt man eine ständige Kontrolle, weil sich während des Druckens einer Auflage die Druckbedingungen ändern können, z.B. Raumtemperatur, Papierbeschaffenheit, Luftfeuchtigkeit, Farbkonsistenz usw.During the start-up process, but also during the printing process, it is necessary to check the quality of the printed product. In the first case, you want to achieve the desired image quality as quickly as possible, i.e. Minimization of waste, and in the second case constant control is required because printing conditions can change during the printing of an edition, e.g. Room temperature, paper texture, air humidity, color consistency, etc.

Als Maßstab für die geforderte Sollqualität dient ein Muster, der sogenannte Abmusterungsbogen. Der jeweils zu prüfende Probebogen wird mit dem Abmusterungsbogen verglichen, wobei dieser Vergleichsdurchführung ein hoher Stellenwert zugeschrieben wird, denn selbst kleinste, nur mit einer Lupe sichtbare Ungenauigkeiten bei der Bildzusammensetzung führen zu einer Veränderung der Druckqualität. Um die Vergleichsdurchführung zu erleichtern, sollte der Abmusterungsbogen zum Probebogen in einem günstigen Anordnungsverhältnis stehen. Zu diesem Zwecke wird der Probebogen auf einen zum Betrachter hin abgeschrägten Abmusterungstisch gelegt und der Abmusterungsbogen auf der dem Betrachter gegenüberliegenden Seite des Abmusterungstisches angebracht.A sample, the so-called sample sheet, serves as a benchmark for the required target quality. The test sheet to be checked in each case is compared with the sampling sheet, with this comparison being given a high priority, because even the smallest inaccuracies in the image composition that are only visible with a magnifying glass lead to a change in the print quality. In order to facilitate the comparison, the sample sheet should be in a favorable arrangement ratio to the sample sheet. For this purpose, the sample sheet is placed on a matching table slanted towards the viewer and the matching sheet is attached to the side of the matching table opposite the viewer.

Bekannt ist das Anbringen des Abmusterungsbogens an einem Galgen, der gleichzeitig Träger für eine Befestigung der Tischbeleuchtung ist (CPC-Pult - HEIDELBERGER DRUCKMASCHINEN AG, siehe Heidelberger Nachrichten 3/37 1979 - ).It is known to attach the sample sheet to a gallows, which at the same time is a support for fastening the table lighting (CPC desk - HEIDELBERGER DRUCKMASCHINEN AG, see Heidelberger Nachrichten 3/37 1979 -).

Ferner ist das Anbringen des Abmusterungsbogens an einer senkrecht zum Abmusterungstisch feststehenden Wand bekannt (Werbeprospekt der Firma Just, 7315 Weilheim).It is also known to attach the sample sheet to a wall which is fixed perpendicular to the sample table (advertising brochure from Just, 7315 Weilheim).

Die o.g. Methoden zur Anbringung des Abmusterungsbogens haben jedoch den Nachteil, daß der Betrachter sich über den Abmusterungstisch beugen muß, wenn er einen Qualitätsvergleich zwischen dem Abmusterungsbogen und dem zu prüfenden Druckbogen herstellen will. In Anbetracht der Größe der Abmusterungstische stellt dies nicht nur für kleinere Personen ein nicht unerhebliches Problem dar.The above Methods of attaching the sample sheet have the disadvantage, however, that the viewer has to bend over the sample table if he wants to make a quality comparison between the sample sheet and the printed sheet to be checked. In view of the size of the sampling tables, this is a significant problem not only for smaller people.

Aus der Gebrauchsmuster-Offenlegung (IP 58-39866/39865) ist ein horizontales Verschieben des Abmusterungsbogenhalters neben den Abmusterungstisch bekannt. Bei dieser Methode erübrigt sich zwar das Beugen über den Abmusterungstisch, da der Betrachter neben den Tisch treten kann, und er somit näher am seitlich verschobenen Abmusterungsbogen steht; der Nachteil dieser Methode ist jedoch, daß der Betrachter seine Betrachterposition verlassen muß, und er zwangsläufig dadurch den auf dem Abmusterungstisch liegenden Bogen aus seinem Blickfeld verliert. Dies wirkt sich sehr negativ aus, da bei einem Vergleich zweier Objekte die besseren Ergebnisse erzielt werden, wenn die zu vergleichenden Objekte sehr dicht beieinanderliegen. Der Erfindung liegt die Aufgabe zugrunde, den Soll- und Ist-Vergleich der Druckerzeugnisse für den Betrachter zu vereinfachen und die Qualität zu steigern.From the utility model disclosure (IP 58-39866 / 39865) a horizontal shift of the sample sheet holder next to the sample table is known. This method eliminates the need to bend over the matching table because the viewer can step next to the table and is thus closer to the laterally shifted matching sheet; the disadvantage of this method, however, is that the viewer has to leave his viewer position and inevitably lose sight of the sheet lying on the examination table. This has a very negative effect, because when comparing two objects, the better results are achieved if the objects to be compared are very close together. The invention has for its object to simplify the target and actual comparison of the printed products for the viewer and to increase the quality.

Diese Aufgabe wird erfindungsgemäß entsprechend dem Anspruch 1 gelöst.This object is achieved according to claim 1.

Der Vorteil der Erfindung ist in der Umkehrung der bisherigen Arbeitsweise zu sehen, nämlich, daß der Abmusterungsbogen zum Betrachter hin- und wegbewegbar angeordnet ist und die jeweilige Position freischwebend erhalten bleibt. Dadurch, daß der Betrachter in seiner Betrachterposition verbleiben kann, und er den Abmusterungsbogen individuell positionierbar vor sich hat, ist eine exakte Vergleichsdurchführung bei minimaler Blickrichtungsänderung zu erzielen. Der Vergleichsvorgang wird dadurch beschleunigt und die Qualität gesteigert.The advantage of the invention is to be seen in the reversal of the previous method of operation, namely that the pattern sheet is arranged so that it can be moved back and forth to the viewer and that the respective position remains freely floating. The fact that the observer can remain in his observer position and that he has the pattern sheet individually positionable in front of him, enables an exact comparison to be carried out with a minimal change in viewing direction. This speeds up the comparison process and increases the quality.

Um ein individuelles Kippen und Heranführen des Abmusterungsbogenhalters zu gewähren, sind nach einer weiteren Ausbildung der Erfindung die Verbindungen zwischen Abmusterungsbogenhalter und Gestänge sowie Gestänge und Galgen mit einem Gelenk versehen. Eine weitere Ausbildung der Erfindung ist die Verwendung einer Gasdruckfeder, die der Erzielung einer leichten Bewegungsdämpfung und zum Gewichtsausgleich dient.In order to allow the sampling bow holder to be tilted and brought up individually, according to a further embodiment of the invention, the connections between the sampling bow holder and the linkage as well as linkage and gallows are provided with a joint. Another embodiment of the invention is the use of a gas pressure spring, which is used to achieve a slight movement damping and for weight compensation.

Das leichte Anbringen des Abmusterungsbogens an den Abmusterungsbogenhalter ist in einer weiteren Ausführung der Erfindung dadurch gewährt, indem ferromagnetisches Material für den Abmusterungsbogenhalter Verwendung findet, so daß ein Anbringen des Abmusterungsbogens mittels Dauermagneten ermöglicht wird.In a further embodiment of the invention, the easy attachment of the pattern sheet to the pattern sheet holder is ensured by using ferromagnetic material for the pattern sheet holder, so that the pattern sheet can be attached by means of permanent magnets.

Denkbar wäre auch die Verwendung eines weichen Haltermaterials, wie Holz, das ein Anheften (z.B. mittels Reißzwecke) des Abmusterungsbogens erlaubt. Die gleiche Wirkung ist auch erzielbar, wenn auf den Abmusterungsbogenhalter ein weicher Belag aufgebracht wird.It would also be conceivable to use a soft holder material, such as wood, which allows the pattern sheet to be attached (e.g. by means of a thumbtack). The same effect can also be achieved if a soft covering is applied to the matching sheet holder.

Zur Verringerung des Haltergewichtes ist in einer weiteren Ausführung der Erfindung das Haltermaterial perforiert.In a further embodiment of the invention, the holder material is perforated to reduce the holder weight.

In einer weiteren Ausführung der Erfindung ist an der Unterkante des Abmusterungsbogenhalters eine Ablage angebracht, die der Aufnahme verschiedener Utensilien, wie z.B. der Lupe, dient.In a further embodiment of the invention, a tray is attached to the lower edge of the sample sheet holder, which is used to hold various utensils, e.g. the magnifying glass.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below.

In der Zeichnung ist in Seitenansicht eine Anordnung zur Abmusterung eines Druckerzeugnisses zu sehen, bestehend aus den Grundelementen, wie einem Abmusterungstisch 1, einem Galgen 2, einem Oberlicht 9 und einem Abmusterungsbogenhalter 3. Der Abmusterungstisch 1 dient dabei als Auflagefläche für den jeweils zu prüfenden Probebogen. Der Abmusterungsbogenhalter 3 dient der Aufnahme des Abmusterungsbogens. An der dem Galgen 2 gegenüberliegenden Seite des Abmusterungstisches befindet sich die Betrachterposition. Von dieser Position aus hat der Betrachter die Möglichkeit, einerseits den Probebogen und andererseits den Abmusterungsbogen in Augenschein zu nehmen. Mit Hilfe des Oberlichtes 9 ist die erforderliche Ausleuchtung der zu prüfenden Bogen gewährleistet.In the drawing, a side view of an arrangement for sampling a printed product can be seen, consisting of the basic elements, such as a matching table 1, a gallows 2, a skylight 9 and a matching sheet holder 3. The matching table 1 serves as a support surface for the respective sample sheet to be tested . The sample sheet holder 3 is used to hold the sample sheet. The observer position is on the side of the sampling table opposite the gallows 2. From this position, the viewer has the opportunity to inspect the sample sheet on the one hand and the sample sheet on the other. With the help of the skylight 9, the required illumination of the sheets to be tested is ensured.

Den individuellen Bedürfnissen des Betrachters entsprechend, besteht durch die Anordnung des Gelenkes 6 die Möglichkeit, den Abmusterungsbogenhalter dem Betrachter zuzuführen und auch wieder von ihm wegzuführen. Die vom Betrachter gewählte Position des Abmusterungsbogenhalters 3 bleibt freischwebend erhalten, der dazu notwendige Gewichtsausgleich wird mittels einer Gasdruckfeder 7 hergestellt. Diese Gasdruckfeder 7 ist dabei auf einer Seite mit dem Galgen, auf der anderen Seite mittels eines Hebelarmes 8 mit dem Gestänge 4 verbunden. Die Ausgestaltung des Gelenkes 5, das die Verbindung zwischen dem Gestänge 4 und dem Abmusterungsbogenhalter 3 herstellt, ermöglicht einerseits ein Kippen des Abmusterungsbogenhalters um eine horizontale Achse und andererseits das selbständige Verharren der gewählten Kipposition des Abmusterungsbogenhalters.According to the individual needs of the viewer, the arrangement of the joint 6 offers the possibility of guiding the sample sheet holder to the viewer and also guiding it away from him. The position of the sample sheet holder 3 selected by the viewer remains free-floating, the necessary weight compensation is produced by means of a gas pressure spring 7. This gas pressure spring 7 is connected on one side to the boom, on the other side by means of a lever arm 8 to the linkage 4. The design of the joint 5, which establishes the connection between the linkage 4 and the sample sheet holder 3, on the one hand enables the sample sheet holder to be tilted about a horizontal axis and on the other hand allows the selected tilting position of the sample sheet holder to remain on its own.

Ein selbständiges Verharren in der gewählten Kipposition des Abmusterungsbogenhalters kann, je nach Ausgestaltung des Gelenkes 5, durch entsprechende Reibungskräfte innerhalb des Gelenkes 5 oder auch durch eine Arretierung am Gelenk 5 erzielt werden.Depending on the design of the joint 5, an independent persistence in the selected tilting position of the matching bow holder can be achieved by appropriate frictional forces within the joint 5 or also by a lock on the joint 5.
