Abstract

A test form for determining the state and the setting of the dampening unit system of an offset printing press and to a method for this setting using the test form. The test form makes it possible to derive an application amount of dampening solution and to represent precisely possible defects in the dampening unit system of the printing unit of an offset press. The test form is characterized by a printing plate having a mirror-symmetrical arrangement of two pattern profiles which have a large area and extend substantially transversely over the entire printing plate, wherein the mirror plane (line) extends transversely with respect to the printing direction, and the pattern profiles, in relation to the area coverage, decrease starting from one edge of the printing plate as far as the mirror plane (line) and increase again from the latter in the direction of the opposite edge.

Description

Die Erfindung betrifft eine Testform zur Bestimmung des Zustandes und der Einstellung des Feuchtwerksystems einer Offsetdruckmaschine gemäß dem Oberbegriff des Patentanspruchs 1 sowie ein Verfahren zur Einstellung gemäß dem Oberbegriff des Patentanspruchs 14.The invention relates to a test form for determining the state and the setting of the dampening system of an offset printing machine according to the preamble of patent claim 1 and a method for adjustment according to the preamble of patent claim 14.

Bisher erfolgte die Einstellung der richtigen Feuchtmitteldosierung empirisch in einem iterativen Vorgehen. Hierbei gab es keine messtechnisch unterlegte Aussage über das bestmöglich erreichbare Ergebnis noch über eventuelle technische Mängel am Zustand des Feuchtwerkssystems.So far, the adjustment of the correct dosage of dampening agent has been carried out empirically in an iterative procedure. Here, there was no metrologically underlined statement about the best achievable result nor about any technical defects in the state of the dampening system.

Eine Testform ist in EP-A-0 388 697 offenbart.A test form is in EP-A-0 388 697 disclosed.

Aufgabe der Erfindung ist die Schaffung einer Testform, die die Ableitung der bestmöglichen Feuchtmittelauftragsmenge und eine präzise Darstellung möglicher Defekte im Feuchtwerksystem des Druckwerks einer Offsetmaschine ermöglicht.The object of the invention is to provide a test form which allows the derivation of the best possible dampening solution application amount and a precise representation of possible defects in the dampening system of the printing unit of an offset machine.

Gelöst wird diese Aufgabe erfindungsgemäß mit den Merkmalen des Patentanspruchs 1.This object is achieved according to the invention with the features of claim 1.

Vorzugsweise Weiterbildungen ergeben sich aus den Unteransprüchen.Preferably further developments emerge from the subclaims.

Zum Verständnis der Erfindung sei zunächst erwähnt, dass unter dem nachfolgend verwendeten Begriff "Rasterverlauf" ein Raster verstanden wird, dessen Flächendeckung sich über eine vorgegebene Fläche verändert. Im vorliegenden Fall ist diese Veränderung beim Rasterverlauf nur in Druckrichtung vorgesehen.
Unabhängig von dem Begriff Rasterverlauf wird auch der Begriff "Rasterfeld" verwendet. Hierbei handelt es sich um eine innerhalb eines definierten Bereiches festgelegte aber gleichbleibende Flächendeckung.To understand the invention, it should first be mentioned that the term "raster profile" used below is understood to mean a raster whose areal coverage changes over a predetermined area. In the present case, this change in the raster profile is provided only in the printing direction.
Regardless of the term raster, the term "raster field" is used. This is a uniform area coverage defined within a defined area.

Generell gilt es, die geringste mögliche Menge Feuchtmittel (In der Regel Wasser mit neutralem PH-Wert und chemischen Zusätzen) zu ermitteln und konstant zu halten, die auf eine Offsetdruckform aufzutragen ist um ein Höchstmass an Druckqualität (Bildwiedergabe und Weiterverarbeitungseigenschaften) zu erzielen.In general, the lowest possible amount of dampening solution (usually water with neutral pH value and chemical additives) must be determined and kept constant, which must be applied to an offset printing form in order to achieve maximum print quality (image reproduction and further processing properties).

Die Feuchtmittelauftragsmenge in einem Feuchtwerksystem eines Druckwerkes wird in der Regel über eine Dosiereinrichtung erlangt, die technisch unterschiedlich ausgelegt sein können (Heberfeuchtwerke, Filmfeuchtwerke, indirekter Farbauftrag über Farbwalzen, Bürstenfeuchtwerke und Schleuderfeuchtwerke). Die vorliegende Beschreibung gilt für alle Arten dieser Dosierungssysteme, soll hierbei allerdings am Beispiel der "Tauchwalze", dem gängigsten Verfahren beschrieben werden.The dampening solution application rate in a dampening system of a printing unit is usually obtained via a metering device that can be designed differently in terms of technology (lift dampening, film dampening, indirect inking via ink rollers, brush dampening units and centrifugal dampening units). The present description applies to all types of these dosing systems, but should be described here using the example of the "dipping roller", the most common method.

Die Testform bestehend im Wesentlichen aus einer Druckplatte mit zwei spiegelbildlich angeordneten Rasterverlaufsflächen, die durch Belichtung mit einer Auflösung von 60-80l/cm, auf der Druckplatte erzeugt worden sind.
Der Rasterverlauf ist dabei so gestaltet, dass die Flächendeckung in Druckrichtung bis zur Spiegelebene (linie) abnimmt und dementsprechend die Wasseraufnahmefähigkeit zunimmt. Da die Anordnung spiegelbildlich ist, ist der Rasterverlauf nach der Spiegelebene (linie) entsprechend umgekehrt, d.h. die Flächendeckung nimmt zu und damit die Wasseraufnahmefähigkeit ab.
Dieser Rasterverlauf führt dazu, dass bei einem entsprechend eingestelltem Feuchtwerksystem auf dem gedruckten Bogen eine Abrißkante erscheint, bei der eine Trennung zwischen freilaufendem und nicht freilaufendem Raster erfolgt. Aus dem Verlauf und der Lage der Abrißkante können nun Hinweise für eine Einstellung des Feuchtwerksystem oder auch Fehler bzw. Beschädigungen dieses System abgeleitet werden, wie dies nachfolgend noch beschrieben wird.The test form consisting essentially of a printing plate with two mirror-image arranged raster scan surfaces, which have been produced by exposure to a resolution of 60-80 l / cm on the printing plate.
The grid pattern is designed so that the area coverage decreases in the printing direction to the mirror plane (line) and accordingly increases the water absorbency. Since the arrangement is mirror-image, the raster pattern is correspondingly reversed according to the mirror plane (line), ie the area coverage increases and thus the water absorption capacity decreases.
This raster course causes a tear-off edge to appear on the printed sheet in the case of a correspondingly adjusted dampening system, in which a separation between free-running and non-free-running raster takes place. From the course and the position of the demolition edge hints for a setting of the dampening system or errors or damage to this system can now be derived, as will be described below.

Zur Bestimmung des technischen Zustandes des Feuchtwerksystems und der optimalen Feuchtmittelauftragdosierung dient der großflächige Verlauf, der mit einer Flächendeckung von 80% auf 2% zur Bogenmitte abfällt und dort vorzugsweise durch einen Volltonstreifen beendet wird. Dieser Verlauf findet sich dann in der zweiten Bogenhälfte gespiegelt wieder.To determine the technical condition of the dampening system and the optimal dampening solution metering serves the large-scale profile, which drops with a coverage of 80% to 2% to the center of the sheet and is preferably terminated by a solid strip. This course is then mirrored again in the second half of the sheet.

Für die eigentliche Auswertung des Druckes ist es sehr vorteilhaft einen sogenannten "Dichtesprung" nach dem ersten viertel des Rasterverlaufes in Druckrichtung vorzusehen. Vor diesem Dichtesprung stoppt der Verlauf bei einer Flächendeckung von 50% und verharrt dort über eine Fläche von beispielsweise 8 mm, die sich über die gesamte Plattenbreite - also quer zur Druckrichtung - zieht. Erst nach diesem Streifen gleicher Flächendeckung (50%) setzt sich der abfallende Verlauf fort, allerdings dann mit einem Startpunkt von 47% Flächendeckung, An dieser Kante soll sich im folgenden Prozessablauf die Abrißkante orientieren. Der sich fortsetzend abfallende Verlauf endet dann mit einer Flächendeckung von 2% in der Spiegelebene (linie) und wird ggf. von dem bereits erwähnten Volltonstreifen begrenzt.
Die Abrißkante trennt die Bereiche in denen die Rasterverlaufsfläche mangels ausreichendem Feuchtmittelauftrag mit Farbe überfrachtet (verschmiert) sein kann von solchen Flächen, deren Rasterpunkte bereits scharf definiert sind. An der kritischen Flächenkombination des Dichtesprunges machen sich geringste Dosierungs-Veränderungen sichtbar. Die Tauchwalze, die für die Feuchtmitteldosierung verantwortlich ist muss so eingestellt sein, dass sich die Schmiergrenze möglichst gradlinig an dem gedruckten Dichtesprung quer zur Druckrichtung entlang zieht.For the actual evaluation of the pressure, it is very advantageous to provide a so-called "density jump" after the first quarter of the raster course in the printing direction. Before this density jump, the course stops at a surface coverage of 50% and remains there over an area of, for example, 8 mm, which extends over the entire plate width - ie transversely to the printing direction. Only after this strip of equal area coverage (50%), the sloping course continues, but then with a starting point of 47% area coverage, At this edge, the tear-off edge should be oriented in the following process flow. The continuing decline then ends with an area coverage of 2% in the mirror plane (line) and is possibly limited by the already mentioned solid strip.
The tear-off edge separates the areas in which the raster running surface can be overloaded (smudged) with color due to the lack of sufficient dampening agent application from surfaces whose raster points are already sharply defined. At the critical area combination of the density jump, the smallest dose changes become visible. The fountain roller, which is responsible for the dampening solution dosage, must be set so that the lubrication limit runs as straight as possible along the printed density jump transversely to the printing direction.

An beiden Plattenrändern und in der Plattenmitte sind rechteckige Rasterfelder mit abgestufter Flächendeckung vertikal angeordnet. Diese 3 Rasterstufenkeile dienen zur Bestimmung der Druckkennlinie. Diese Bestimmung erfolgt nachdem der Prozess der Feuchtwerkjustage stattgefunden hat und die bestmögliche Feuchtmittelauftragsmenge ermittelt wurde. Die Anordnung der Stufenkeile mittig und an den beiden Plattenrändern, gesehen in Druckrichtung stellt sicher, dass über den gesamten Druckbogen die gleiche Druckkennlinie erzielt wird. Die Toleranz zwischen den Messwerten in Druckrichtung darf den Dichtewert von 1 % nicht überschreiten. Gleichem Zweck dient die balkenfoermige Volltonfläche. Hierbei soll die maximale Druckdichte (Farbauftragsmenge) gemessen werden, die über die Bogenbreite frei von Schwankungen sein soll.At both plate edges and in the middle of the plate, rectangular grids with graded area coverage are arranged vertically. These 3 raster step wedges serve to determine the pressure characteristic. This determination takes place after the process of the dampening adjustment has taken place and the best possible amount of dampening solution has been determined. The arrangement of the step wedges in the middle and at the two plate edges, as seen in the printing direction, ensures that the same printing characteristic is achieved over the entire printing sheet. The tolerance between the measured values in printing direction must not exceed the density value of 1%. The same purpose is the bar-shaped solid surface. Here, the maximum print density (amount of ink application) is to be measured, which should be free of fluctuations over the sheet width.

Über die gesamte Breite der Testformmitte zieht sich ein Volltonbalken der - nach einer Ausführung - durch drei rechteckige Felder mit 50% Flächendeckung unterbrochen ist. Diese Rasterfelder befinden sich in der Mitte und an den beiden Extremen des Volltonbalkens. Bei korrekten Justagen des Feuchtwerks muss die Tonwertzunahme in den drei Rasterfeldern gleich sein. Die Toleranz von 1 % Dichte soll dabei nicht überschritten werden.
Eine andere Ausgestaltung sieht vor, dass der Volltonbalken von einem Rahmen mit einer 50% Flächendeckung umgeben ist. Die Auswertung kann dann entsprechend erfolgen.Over the entire width of the center of the test form, a solid tone bar is drawn which, according to one embodiment, is interrupted by three rectangular fields with 50% area coverage. These grids are in the middle and at the two extremes of the solid bar. If the dampening unit is correctly adjusted, the dot gain in the three grids must be the same. The tolerance of 1% density should not be exceeded.
Another embodiment provides that the solid tone bar is surrounded by a frame with a 50% area coverage. The evaluation can then be done accordingly.

Am unteren Rand der Testform oder Druckplatte sind quer zur Druckrichtung über die gesamte Breite Rasterfelder mit unterschiedlicher Flächendeckung angeordnet. Kombiniert sind diese mit einem Volltonbalken, der sich ebenfalls über die volle Breite quer zur Druckrichtung erstreckt. Diese Rasterfelder weisen drei unterschiedliche Flächendeckungen auf und wiederholen sich über die Plattenbreite. Die Felder mit den Flächendeckungen 94%, 90% und 80% sind ausgewählt, um Feinjustagen der Feuchtmitteldosierung vorzunehmen. Bei diesen hohen Flächendeckungen mit kleinsten, "freiliegenden" Wasser führenden Flächen lassen sich feinste Abweichungen von der optimalen Feuchtmittelzuführung erkennen. Diese Anordnung soll die Frage nach der "unteren Schmiergrenze" beantworten. Die Verteilung der Rasterflächen über die Plattenbreite gibt Aufschluss über die Gleichmaessigkeit der Ergebnisse.At the lower edge of the test form or printing plate, grids with different area coverage are arranged across the entire width transversely to the printing direction. These are combined with a full-tone bar, which also extends across the full width transverse to the printing direction. These grids have three different surface coverages and repeat over the plate width. Fields with area coverage 94%, 90% and 80% are selected to make fine adjustments to the fountain solution dosage. At these high surface coverages with the smallest, "exposed" water-bearing surfaces, the finest deviations from the optimum dampening solution supply can be recognized. This arrangement should answer the question of the "lower lubrication limit". The distribution of grid areas across the plate width provides information about the uniformity of the results.

Die Schmiergrenze (Abrißkante) ist definiert als "Trennlinie" zwischen zwei Bereichen, wobei der eine sich mit Farbe überfrachtet darstellt und der andere normal Farbe angenommen hat.The smear boundary is defined as a "dividing line" between two areas, one representing color overload and the other normal color.

Zeichnet sich nach der Starteinstellung (Grundeinstellung der Tauchwalze) ein stark welliger Abriss zwischen den beiden genannten Bereichen ab, so gilt die Einstellung als nicht ausreichend. Die Ursachen können die genannte Falscheinstellung sein, die es nun gilt messtechnisch zu erfassen und in wenigen Schritten zu optimieren, oder es können Defekte im Feuchtwerksystem (falsches Walzenmaterial, verbrauchte, abgenutzte Walzen) selbst sein, die nur durch einen Emeuerungs- Maßnahmen behoben werden können.If, after the start setting (basic setting of the fountain roller), a very wavy demolition occurs between the two areas mentioned above, the setting is considered insufficient. The causes may be the aforementioned incorrect position, which now applies to be measured and optimized in a few steps, or there may be defects in the dampening system (wrong roll material, used, worn rollers) itself, which can only be remedied by a Emeuerungs- measures ,

In fast allen Fällen wird eine sichtbare Schmiergrenze sichtbar, die anhand ihres Verlaufes auf einen mehr oder minderen Optimierungsbedarf hinweist. Im Falle einer sichtbaren Schmiergrenze verlauft diese in Wellenform horizontal entlang des Dichtesprunges, wobei die Wellenform, also die Abstände zwischen den Wellentälern und Wellenspitzen von leicht bis extrem ausgebildet sein können. Die Ausprägung der Amplituden der sich in Druckrichtung über den Bogen ziehende gewellte Schmiergrenze gibt einen ersten Aufschluss über die notwendigen Korrekturmaßnahmen.In almost all cases, a visible lubrication limit becomes visible, which points to a greater or lesser need for optimization based on its course. In the case of a visible lubrication limit this runs in a waveform horizontally along the density jump, the waveform, so the distances between the troughs and wave peaks from light to extreme can be formed. The expression of the amplitudes of the corrugated lube boundary pulling over the sheet in the pressure direction provides a first indication of the necessary corrective measures.

Durch den gespiegelten Rasterverlauf entstehen auf denTestdrucken zwei im wesentlichen gespiegelt verlaufende Abrißkanten. Weicht deren Verlauf oder Form stärker voneinander ab als tolerierbar, weist dies auf Defekte oder Fehleinstellungen des Feuchtwerksystems hin.Due to the mirrored raster pattern, two essentially mirrored demolition edges are formed on the test prints. If their course or shape deviates more strongly than tolerable, this indicates defects or incorrect settings of the dampening system.

Durch verändern der Tauchwalzengeschwindigkeit (Umdrehung in m/s, dargestellt durch %-wert eingaben am Feuchtwerk) wird nun mehr oder weniger Feuchtmittel auf die Druckform übertragen. Dies führt zur Verlagerung der Schmiergrenze.By changing the dipping roller speed (rotation in m / s, represented by% value input at the dampening unit), more or less dampening solution is transferred to the printing form. This leads to the shift of the lubrication limit.

Durch gezielte Veränderung der Tauchwalzengeschwindigkeit, also der Menge zugeführten Feuchtmittel werden die Amplitudenspitzen der Schmiergrenzenwelle an den Dichtesprung "hingefahren".
Gelingt dies nicht, so ist der Zuführungsbedarf an Feuchtmittel so hoch, dass ein qualitativ hochwertiger Druck nicht mehr erreicht werden kann. Als Maßnahme bleibt dann nur die Erneuerung des Tauchwalzensystems oder des gesamten Feuchtwerks.By deliberately changing the dipping roller speed, that is to say the quantity of dampening solution supplied, the amplitude peaks of the lubricant limit shaft are "driven" to the density jump.
If this is not successful, the supply requirement of dampening solution is so high that high-quality printing can no longer be achieved. As a measure then remains only the renewal of the dipping roller system or the entire dampening system.

Liegt der Kurvenzug der Schmiergrenze jedoch so, dass mit einer Veränderung der Tauchwalzengeschwindigkeit zum Beispiel bei 40% Grundeinstellung von 2% die Spitzen der Amplituden an dem Dichtesprung anliegen, dann ist die Feuchtmittelzuführung (entspricht ca. 5% mehr Feuchtmittel) bestens eingestellt und die Tauchwalze technisch einwandfrei.However, if the curve of the lubrication limit is such that the peaks of the amplitudes are adjacent to the density jump with a change in the dipping roller speed, for example at 40% basic setting of 2%, then the dampening solution supply (corresponding to approx. 5% more dampening solution) is optimally adjusted and the dipping roller technically flawless.

Erreichen die Amplituden des durch die Schmiergrenze sichtbaren Kurvenzugs mittels Veränderung der Tauchwalzengeschwindigkeit im Toleranzbereich von 2% (entspricht ca. 5% mehr Feuchtmittel) nicht den Dichtesprung, so ist eine höhere Feuchtmittelmenge (bis maximal 20%) erforderlich. Genügt diese Auftragsmenge nicht um die Amplituden an den Dichtesprung zu führen, so hat die Tauchwalze einen technischen Defekt und muss getauscht werden.If the amplitudes of the curve curve visible through the lubrication limit do not reach the density jump by changing the dipping roller speed in the tolerance range of 2% (corresponding to approx. 5% more dampening solution), a higher dampening solution quantity (up to a maximum of 20%) is required. If this order quantity does not suffice to guide the amplitudes to the density jump, then the dipping roller has a technical defect and must be exchanged.

Die einzelnen Verfahrensschritte für die Durchführung des Testes und der nachfolgenden Justierung sind wie folgt:

  • Schritt1:
    Belichten der Testformelemente in einem Direktbebilderungssystem für Offsetplatten zur Herstellung der Druckplatte. Dies ist allgemein bekannt.
  • Schritt 2:
    Nach Einbringen der Platte in ein Offsetdruckwerk der zu justierenden Offsetdruckmaschine soll die Farbgebung über das Farbwerk nach Vorgabe des Maschinenherstellers dosiert werden. Hierbei kann die Farbzonenvoreinstellung des Farbwerks über die CIP 3-Vorberechnung der zu erwartenden Flächendeckung aus dem digitalen Datenbestandes der Testform herangezogen werden.
  • Schritt 3:
    Es gibt Tauchwalzen die mit unterschiedlichem Schoepfvolumen ausgestattet sind. Die Geschwindigkeit der Tauchwalze wird je nach deren Schoepfvolumen auf etwa 30%, 40% oder 50% eingestellt (100% bedeutet eine Umdrehungsgeschwindigkeit x zur Druckgeschwindigkeit).
    Es wird ein erster Testdruck durchgeführt, um die Lage der Abrißkante bei üblicher Einstellung festzustellen.
    Nun muss die Tauchwalze so eingestellt werden, dass die Abrißkante nahe an den Dichtesprung herangebracht wird, wobei aus der Wellenform Rückschlüsse auf eventuelle Fehler der Tauchwalze oder des Feuchtwerksystems - wie vorher beschrieben - gezogen werden können. Die Abrißkante sollte möglichst gleichmäßig innerhalb der Toleranz an diesem Dichtesprung quer zur Druckrichtung liegen. Die Toleranz beträgt bei 30% Tauchwalzengeschwindigkeit 1,5%, bei 40% Geschwindigkeit 2% und bei 50% Tauchwalzengeschwindigkeit 2,5%
The individual process steps for carrying out the test and the subsequent adjustment are as follows:
  • Step 1:
    Exposing the test form elements in a direct imaging system for offset plates to make the printing plate. This is well known.
  • Step 2:
    After introducing the plate into an offset printing unit of the offset printing machine to be adjusted, the coloring is to be metered in via the inking unit as specified by the machine manufacturer. In this case, the color zone presetting of the inking unit can be used via the CIP 3 precalculation of the expected area coverage from the digital data stock of the test form.
  • Step 3:
    There are dipping rollers which are equipped with different Schoepfvolumen. The speed of the dipping roller is set to about 30%, 40% or 50% depending on the capacity of the dipping roller (100% means one revolution speed x the printing speed).
    It is carried out a first test pressure to determine the position of the tear-off edge in the usual setting.
    Now the fountain roller must be adjusted so that the tear-off edge is brought close to the density jump, whereby the waveform can be drawn conclusions on any errors of the fountain roller or the dampening system - as previously described. The tear-off edge should be as evenly as possible within the tolerance at this density jump transversely to the printing direction. The tolerance is 1.5% at 30% dipping roller speed, 2% at 40% speed and 2.5% at 50% dipping roller speed

Verläuft die Abrisskante nach den oben beschriebenen Testdrucken mit zwischendurch durchgeführten Korrekturen des Feuchtwerkes/Feuchtmittelzufuhr mit geringen Amplitudenspitzen im wesentlichen entlang des gedruckten Dichtesprungs, dann kann in einem weiteren Schritt durch Feuchtmittelzufuhränderung die Abrisskante außerhalb des Druckes "gefahren" werden um dann mit dieser Einstellung nach erfolgreich beendeter Testphase die Druckmaschine im Normalbetrieb zu betreiben.Runs the trailing edge after the test prints described above with occasionally carried out corrections of dampening / dampening with low amplitude peaks substantially along the printed density jump, then in a further step by Feuchtmittelzufuhränderung the trailing edge outside the pressure "driven" to then with this setting after successful finished test phase to operate the printing press in normal operation.

Die Erfindung soll auch mit Bezug auf die Zeichnungen noch erläutert werden.
In den Figuren 1-5 ist jeweils die Druckplatte dargestellt und mit 1 bezeichnet.
Die spiegelbildliche Anordnung der Rasterverläufe 2 und 3 wird durch eine Volltonfläche 6 getrennt. Bei dem gezeigten Ausführungsbeispiel ist die Volltonfläche von einem Rahmen 15 eingefasst, der eine Flächendeckung von 50% aufweist.
Der Rand der Druckplatte oder Testform ist mit 4 bzw. 5 bezeichnet worden.
Sowohl in den beiden gegenüberliegenden Rändern wie auch dem Volltonstreifen befinden sich Rasterfelder, die mit 10 und 11 bzw. 9 bezeichnet worden sind.
Ferner sind auf der Druckplatte 1 in Druckrichtung angeordnete Rasterfelder 7 und Markierungen 8, deren Wirkung oder Auswertbarkeit vorher beschrieben worden ist, dargestellt.
In der Figur 2 ist der Dichtesprung 12 innerhalb der großflächigen Rasterverläufe 2 und 3 angedeutet.
Die Figuren 3 bis 5 zeigen die Abrißkanten 13 und 14 jeweils in Bezug auf den Dichtesprung, wobei sich aus der Figur 4 die am weitesten an den Dichtesprung angenäherte Abrißkante ergibt, die für die entsprechende Berechnung der richtigen Einstellung der Tauchwalze herangezogen wird. Die im mittleren Bereich erkennbare größere Wasseraufnahme liegt innerhalb eines Toleranzbereiches, so dass sie unbeachtet bleiben kann.The invention will be explained with reference to the drawings.
In the Figures 1-5 in each case the pressure plate is shown and designated 1.
The mirror-image arrangement of the raster courses 2 and 3 is separated by a solid surface 6. In the embodiment shown, the solid surface is enclosed by a frame 15, which has a coverage of 50%.
The edge of the printing plate or test form has been designated 4 and 5, respectively.
Both in the two opposite edges as well as the solid strip are grids, which have been designated 10 and 11 and 9 respectively.
Further arranged on the printing plate 1 in the printing direction grids 7 and marks 8, the effect or readability has been previously described, shown.
In the FIG. 2 the density jump 12 is indicated within the large-scale grid courses 2 and 3.
The FIGS. 3 to 5 show the tear edges 13 and 14 respectively with respect to the Density leap, taking off from the FIG. 4 the most closest to the density jump results in the tearing edge, which is used for the appropriate calculation of the correct setting of the dipping roller. The larger water absorption seen in the middle area lies within a tolerance range, so that it can be ignored.

Claims (14)

  1. A test form for determining the state and the setting of the dampening-unit system of an offset printing press, characterized by a printing plate (1) with a mirror-image arrangement of two large-area grid patterns (2, 3) which extend substantially over the entire printing plate (1), wherein the mirror plane (line) extends transversely to the printing direction and the grid patterns (2, 3) decrease with respect to the area coverage starting from one edge (4, 5) of the printing plate (1) as far as the mirror plane (line) and increase from the said mirror plane (line) in the direction towards the opposite edge (4, 5).
  2. A test form according to Claim 1, characterized in that the area coverage begins at 80 % as viewed from the plate edge and ends at 2 % at the mirror plane (line).
  3. A test form according to Claim 2, characterized in that over the width of the printing plate it has a grid pattern which - starting from the edge of the printing plate (1) - begins with an area coverage of 80 % which decreases to 50 % in the direction towards the mirror plane (line), remains at 50 % there over a narrow portion whilst forming a density jump (12), and then decreases further in the direction towards the mirror plane (line) beginning with an area coverage of 47 % to an approximately 2 % area coverage.
  4. A test form according to any one of the preceding Claims, characterized in that the mirror plane (line) is designed in the form of a narrow full-tone strip (6).
  5. A test form according to any one of the preceding Claims, characterized in that rectangular pattern fields (9, 10, 11) with a stepped area coverage are arranged at intervals transversely to the printing direction on the two edge regions (4, 5) of the printing plate (1) and in the full-tone strip (6).
  6. A test form according to Claim 5, characterized in that the pattern fields (9, 10, 11) are formed with 50 % area coverage in the full-tone strip (6).
  7. A test form according to Claim 5, characterized in that pattern fields with different area coverage are arranged at intervals along the edge region.
  8. A test form according to Claim 7, characterized in that the individual pattern fields have three different area coverages which are repeated.
  9. A test form according to Claim 8, characterized in that the pattern fields have an area coverage of 94 %, 90 % and 80 %.
  10. A test form according to any one of the preceding Claims, characterized in that the full-tone strip (6) is surrounded by a frame with an area coverage of 50 %.
  11. A test form according to any one of the preceding Claims, characterized in that pattern steps, which are arranged at intervals over the printing plate (1) in the printing direction, are provided in order to measure the print characteristic.
  12. A test form according to Claim 11, characterized in that the pattern steps differ by 10 % in each case.
  13. A test form according to any one of the preceding Claims, characterized in that a further full-tone strip is provided which extends from edge to edge of the printing plate in the printing direction and which is used for measuring the ink-taking.
  14. A method of setting a dampening-unit system of an offset printing press whilst using a test form according to the preceding Claims, characterized in that a sample print is first made with a first setting of the dampening-unit system in order to determine the position of a tear-off edge (13, 14) on the printed sheet, after that the speed of the dipping roller of the dampening-unit system is altered in such a way that the tear-off edge (13, 14) comes to be situated close to the density jump (12), wherein the said procedure is optionally repeated a multiplicity of times, and an evaluation of the state of the dipping roller and/or of the dampening-unit system is made from the pattern of the tear-off edge (13, 14) transversely to the printing direction and the said state is optionally corrected, and after that the tear-off edge (13, 14) is moved just out of the print image by a final change in the supply of dampening agent for normal operation which is to be started following the test phase.
