Description

Die Erfindung betrifft ein Tintenstrahldruckverfahren zum Aufzeichnen von Bildinformation auf ein insbesondere blattförmiges Trägermaterial, wie es gemäß der US 5,717,446 bekannt ist, und gemäß dem Oberbegriff der Ansprüche 1 und 2.The invention relates to an ink jet printing method for recording image information on a particular sheet-shaped carrier material, as known according to US 5,717,446 is, and according to the preamble of claims 1 and 2.

Bei der konventionellen Herstellung von fotografischen Bildern (Prints) wird typischerweise randlos belichtet, das heisst, der Belichtungsbereich ist gleich gross wie oder etwas grösser als das blattförmige Kopiermaterial. Im Falle von bahnförmigem Kopiermaterial ist sinngemäss der Belichtungsbereich gleich breit wie oder etwas breiter als die Kopiermaterialbahn.In the conventional production of photographic images (prints) is typically exposed borderless, that is, the exposure range is the same size as or slightly larger as the sheet-shaped copy material. In the case of web-shaped copy material is analogous the exposure area is the same width as or slightly wider than the copy material web.

In der digitalen Bildherstellung werden häufig Tintenstrahldrucker zum Aufzeichnen der Bildinformation auf das Trägermaterial eingesetzt. Hierbei wird jedoch stets mit Rand gedruckt, wobei der unbedruckte Rand später eventuell auch abgetrennt wird. Der Grund dafür ist darin zu sehen, dass beim Drucken bis an den Rand des Trägermaterials und insbesondere über den Rand hinaus das Druckwerk und die Rückseite der nachfolgenden Bilder verschmutzt würden. Durch das Drucken mit Rand kann aber einerseits die bedruckbare Fläche nicht vollständig ausgenutzt werden und entsteht anderseits unerwünschter Abfall.In digital image production, inkjet printers are often used to record the Image information used on the substrate. However, this is always printed with a border, the unprinted edge may later be separated as well. The reason for this can be seen in that when printing up to the edge of the substrate and in particular beyond the edge the printing unit and the back of the following pictures would be polluted. By printing with edge but on the one hand the printable Area can not be fully exploited and arises on the other unwanted waste.

Aus der US 5,717,446 ist ein Verfahren zur Herstellung von Tintenstrahldruckern bekannt, wobei ein die Bildinformation wiedergebendes Blatt während des Druckvorganges auf einer ein Drainagemittel aufweisenden Unterlage liegt.From US 5,717,446 a method for the production of ink jet printers is known, wherein the image information reproducing sheet during the printing on a a drainage agent containing pad is located.

Die JP 07 009712 offenbart ebenfalls ein Tintenstrahldruckverfahren, wobei hier eine saugfähige Einrichtung derart gegenüber einem Druckkopf angeordnet ist, dass diese Tinte absorbieren kann. JP 07 009712 also discloses an ink jet printing method, wherein here an absorbent Device is arranged opposite to a printhead that absorb this ink can.

Durch die vorliegende Erfindung soll nun ein Tintenstrahldruckverfahren der gattungsgemässen Art dahingehend verbessert werden, dass randlos gedruckt werden kann, ohne dass das Druckwerk oder die nachfolgenden Bilder verschmutzt werden.The present invention is now an ink jet printing method of the generic Art be improved so that borderless can be printed without the printing unit or the following pictures are dirty.

Die Lösung dieser der Erfindung zugrundeliegenden Aufgabe ergibt sich aus den im kennzeichnenden Teil der unabhängigen Anspruchs beschriebenen Merkmalen. Besonders vorteilhafte Ausgestaltungen und Weiterbildungen sind Gegenstand der abhängigen Ansprüche.The solution of this problem underlying the invention results from the characterizing Part of the independent claim described features. Particularly advantageous Embodiments and further developments are the subject of the dependent claims.

Gemäss dem Grundgedanken der Erfindung wird also das Trägermaterial während des Drucks auf einer mit Drainagemitteln versehenen Unterlage gehalten. Ausserhalb der Ränder des Trägermaterials auf die Unterlage auftreffende Tintentropfen werden dabei durch die gemäß den Kennzeichen der unabhängigen Ansprüche ausgebildeten Drainagemittel abgeführt und können so weder das Druckwerk noch die nachfolgenden Bilder verschmutzen.According to the basic idea of the invention, therefore, the carrier material is during the Pressurized on a provided with drainage agent pad. Outside the edges The ink droplets striking the base of the carrier material are thereby passed through the drainage means designed according to the characteristics of the independent claims are discharged and so can not pollute the printer or the subsequent pictures.

Im folgenden wird die Erfindung anhand der Zeichnung näher erläutert. Es zeigen:

In the following the invention will be explained in more detail with reference to the drawing. Show it:

A first embodiment of a provided with drainage underlay,
Fig. 2
a detail section through the pad of Fig. 1,
Fig. 3-5
three variants of provided with drainage agents pad and
Fig. 6
a pad provided with drainage means in the form of an endless belt.

Wie aus der Gesamtdarstellung der Fig. 1 hervorgeht, liegt ein zu bedruckendes Blatt B eines Trägermaterials während des Druckvorgangs auf einer Unterlage 20, die als poröse, luft- und flüssigkeitsdurchlässige Plane ausgebildet ist. Die Drainagemittel werden hier also durch die Poren 21 der Platte gebildet (Fig.2).As can be seen from the overall illustration of FIG. 1, a sheet B to be printed lies a support material during the printing process on a base 20, which as a porous, air and liquid permeable tarpaulin is formed. The drainage agents are here so formed by the pores 21 of the plate (Fig.2).

Oberhalb der Unterlage befindet sich ein nur symbolisch angedeutetes Aggregat 11 von Tintenstrahldruckköpfen, die in konventioneller Weise von einem nicht gezeigten Rechner angesteuert sind. Die Unterlage 20 ist an ihrer Unterseite an eine Saugquelle 12 angeschlossen. Durch den von der Saugquelle 12 erzeugten Unterdruck wird einerseits das Blatt B während des Druckvorgangs festgehalten und werden anderseits die ausserhalb des Blatts auf die Unterlage auftreffenden Tintentropfen 13 (Fig.2) durch die poröse Platte durchgesaugt und nach unten abgeführt.Above the base there is an only symbolically indicated aggregate 11 of Inkjet printheads, in a conventional manner from a computer, not shown are controlled. The pad 20 is connected at its bottom to a suction source 12. By the negative pressure generated by the suction source 12 on the one hand, the sheet B are held during the printing process and on the other hand, the outside of the sheet Ink drops 13 (FIG. 2) impinging on the support are sucked through the porous plate and discharged down.

Die in Fig.3 gezeigte Unterlage 30 ist ebenfalls als poröse Plane ausgebildet, weist aber an ihrer Oberseite zusätzlich noch eine gitterförmige Anordnung von Kanälen 31 auf, deren Abstände vorzugsweise so gewählt sind, dass sie zu den gängigen Blattformaten passen. Dadurch wird erreicht, dass das Blatt B jeweils unmittelbar von Kanälen umschlossen ist. Neben das Blatt fallende Tintentropfen fallen somit direkt in die Kanäle und können somit nachfolgende Blätter nicht verschmutzen. Die überschüssigen Tintentropfen werden wiederum durch die poröse Plane abgesaugt. Die Drainagemittel werden hier durch die Poren der Plane sowie durch deren Kanäle 31 gebildet. The pad 30 shown in Figure 3 is also designed as a porous tarpaulin, but indicates their top additionally a grid-shaped arrangement of channels 31, whose Clearances are preferably chosen so that they fit the common sheet formats. This ensures that the sheet B is each enclosed directly by channels. In addition to the leaf falling ink drops fall directly into the channels and thus can do not soil the following leaves. The excess ink drops will turn sucked through the porous tarpaulin. The drainage agents are here through the pores of the Plane and formed by their channels 31.

Die Fig.4 zeigt eine Unterlage 40, welche aus einer porösen Folie 41 und einer darunterliegenden offenzelligen Wabenstruktur 42 besteht. In der Wirkung entspricht diese Ausführungsform derjenigen der Fig.1. Die Drainagemittel werden hier durch die Poren der Folie 41 sowie durch die offenzellige Wabenstruktur 42 gebildet.4 shows a pad 40, which consists of a porous film 41 and an underlying open-cell honeycomb 42 exists. In the effect corresponds this embodiment of that of Fig.1. The drainage agents are going through here the pores of the film 41 and formed by the open-cell honeycomb 42.

Die in Fig.5 gezeigte Unterlage 50 besteht aus nicht-porösem Vollmaterial, ist aber dafür ähnlich wie die Ausführungsform der Fig.3 an ihrer Oberseite mit einem Netzwerk von Kanälen 51 versehen, wobei in den erhabenen Partien zwischen den Kanälen und ggf. auch in den Kanälen selbst Durchgangsöffnungen 52 vorgesehen sind. Die Drainagemittel werden hier also durch die Durchgangsöffnungen 52 und durch die Kanäle 51 gebildet.The pad 50 shown in Figure 5 is made of non-porous solid material, but is similar to the embodiment of Figure 3 at its top with a network provided by channels 51, wherein in the raised portions between the channels and possibly also in the channels themselves passage openings 52 are provided. The drainage means are here so through the through holes 52 and through the channels 51 formed.

Die Fig.6 schliesslich zeigt eine Unterlage in Form eines endlosen Bands 60, welche um zwei Walzen 61 und 62 geschlungen ist. Das Band 60 besteht aus einem saugfähigen oder porösen Material, welches die Drainagemittel bildet. Die überschüssige Tinte wird entweder im Band 60 eingelagert oder wie bei den anderen Ausführungsbeispielen durch das Band 60 durchgesaugt. Im ersten Fall muss das Band 60 natürlich je nach Verschmutzungsgrad von Zeit zu Zeit gereinigt oder ersetzt werden. Bei Bedarf kann das Band 60 auch als Transportmittel für das Blatt B eingesetzt werden.Finally, FIG. 6 shows a support in the form of an endless belt 60, which is wound around two rollers 61 and 62. The band 60 consists of an absorbent or porous material forming the drainage means. The excess Ink is stored either in belt 60 or as in the other embodiments sucked through the band 60. In the first case, the band 60 of course cleaned or replaced from time to time depending on the degree of soiling. at Demand, the belt 60 can also be used as a transport for the sheet B.

Alle vorstehend beschriebenen Ausführungsbeispiele der Unterlage sind sinngemäss auch für bahnförmiges Trägermaterial einsetzbar.All embodiments of the pad described above are analogous can also be used for web-shaped carrier material.
