Description

Die Erfindung betrifft ein Aufzeichnungsmaterial für das Tintenstrahl-Druckverfahren (Ink-Jet-Verfahren).The invention relates to a recording material for the Ink jet printing process (ink jet process).

Das Ink-Jet-Verfahren gehört zu den elektronischen Druckverfahren. Hierbei ist es möglich, Bilder, Texte und Graphiken am Rechner zusammenzusetzen und als Bildschirmhardcopy direkt auszudrucken.The ink jet process is one of the electronic ones Printing process. Here it is possible to add pictures, texts and Compose graphics on the computer and as Print out the screen hardcopy directly.

Bei dem Ink-Jet-Verfahren werden Tröpfchen einer Aufzeichnungsflüssigkeit auf die Oberfläche des Trägermaterials mittels unterschiedlicher Techniken aufgetragen. Bei der Tropfenerzeugung gibt es grundsätzlich zwei Verfahrensvarianten. Bei der Methode der kontinuierlichen Tropfenerzeugung wird unter Hochdruck ein permanenter Tröpfchenstrom aus der Düse getrieben. Die nicht für den Bildaufbau benötigten Tropfen werden durch verschiedene Prinzipien wieder dem Tintenvorratsbehälter zugeführt.In the ink jet process, droplets become one Recording liquid on the surface of the Carrier material using different techniques applied. When it comes to generating drops, there is basically two process variants. With the method the continuous drop generation is under High pressure a permanent stream of droplets from the nozzle driven. The ones not needed for the image construction Different principles make drops again Ink reservoir supplied.

Bei der DropOn-Demand Methode wird nur an den zu bebildernden Stellen auf Abruf ein Tintentröpfchen erzeugt. Durch eine digitale elektronische Steuerung, wie bei dem Hertz Verfahren, ist es möglich, Bilder mit sehr hoher Auflösung direkt aus elektronischen Daten zu erzeugen.The DropOn-Demand method only applies to the an ink droplet on demand generated. Through digital electronic control, such as with the Hertz process, it is possible to take pictures with very high resolution directly from electronic data produce.

Das Ink-Jet-Aufzeichnungsverfahren wird zur Herstellung von Farbgraphiken, Vollfarbkopien und auch für Textdrucke eingesetzt, es umfaßt also ein sehr breites Anwendungsfeld. An das Aufzeichnungsmaterial werden unterschiedliche Anforderungen gestellt wie

  • Punktgröße
  • Lichtstabilität
  • Farbverlaufen (Bleed)
  • Wasserfestigkeit
  • Densität
  • Dimensionsstabilität.
    • The ink jet recording process is used for the production of color graphics, full color copies and also for text prints, so it covers a very wide field of application. Different requirements are placed on the recording material such as
  • point size
  • light stability
  • Bleeding
  • water resistance
  • density
  • Dimensional stability.

    • Das Empfangsmaterial besteht aus einem Trägermaterial, einer Tintenempfangsschicht und gegebenenfalls weiteren Hilfsschichten. Sowohl Trägermaterial als auch Tintenaufnahmeschichtschicht müssen zur Lösung dieser Probleme aufeinander abgestimmt sein.The receiving material consists of a carrier material, an ink-receiving layer and, if appropriate, others Auxiliary layers. Both carrier material as well Ink receiving layer layer need to solve this Problems should be coordinated.

    Ink-Jet-Drucker zur Herstellung fotoähnlicher Drucke benutzen Tinten mit einem hohen Anteil Wasser als Lösungsmittel. Außerdem ist der Tintenauftrag dieser Drucker gößer als bei herkömmlichen Ink-Jet-Druckern. Als Empfangsmaterialien wurden anfangs Folien eingesetzt, da diese sich durch hohe Dimensionsstabilität bei Benetzung mit Wasser auszeichnen. Bei Benutzung herkömmlicher Ink-Jet-Papiere tritt durch den hohen Wassergehalt, der durch die Tintenaufnahmeschicht in die Papierunterlage eindringt, eine Welligkeit in Querrichtung (print cockle) auf. Diese Welligkeit führt zu einem Kontakt mit dem Druckkopf und hat eine Verschlechterung des Druckbilds zur Folge. Außerdem kann der Kopfkontakt zu einer Beschädigung des Empfangsmaterials führen.Ink-jet printer for the production of photo-like prints use inks with a high proportion of water as Solvent. The ink application is also this Printer larger than conventional ink-jet printers. As Reception materials were initially used because foils these are characterized by high dimensional stability when wetted mark with water. When using conventional ink jet papers occurs due to the high water content that passes through the ink receiving layer in the paper base penetrates, a ripple in the transverse direction (print cockle) on. This ripple leads to contact with the Printhead and has a deterioration in the printed image result. In addition, the head contact to one Damage to the receiving material.

    Es ist daher notwendig, für die Herstellung fotoähnlicher Ink-Jet-Drucke ein Empfangsmaterial einzusetzen, bei dem der Papierkern eine hohe Dimensionsstabilität aufweist und somit in der Lage ist, eine große Wassermenge aufzunehmen und die Empfangsschicht die angeführten Anforderungen an die Bild- und Textqualität erfüllt. It is therefore necessary to make photo-like Ink-jet prints use a receiving material in which the paper core has a high dimensional stability and thus is able to use a large amount of water record and the receiving layer the listed Image and text quality requirements met.

    Die GB 2 210 812 A1 beschreibt ein Empfangsmaterial, bestehend aus einer Papierunterlage und einer Tintenaufnahmeschicht. Das Papier enthält Calciumcarbonat als Pigment; an die Papierleimung werden hohe Anforderungen gestellt. Zur Herstellung der Unterlage wird eine Fourdrinier Papiermaschine vorgeschlagen. Die Tintenaufnahmeschicht besteht aus Calciumcarbonat und einem Bindemittel aus kationischem Vinylacetat-Copolymer und einem Polyvinylalkohol mit Silanolgruppen. Das Empfangsmaterial zeichnet sich durch gute Wasserfestigkeit und Bildschärfe aus.GB 2 210 812 A1 describes a receiving material consisting of a paper base and an ink absorption layer. The paper contains calcium carbonate as Pigment; high demands are placed on paper sizing posed. A Fourdrinier paper machine proposed. The Ink absorption layer consists of calcium carbonate and a cationic vinyl acetate copolymer binder and a polyvinyl alcohol with silanol groups. The Receiving material is characterized by good Waterproofness and sharpness.

    Nachteilig ist allerdings das Auftreten einer Welligkeit bei hoher Wasseraufnahme und eine Abnahme der Farbdichte bei höheren AuftragsgewichtenHowever, the occurrence of a ripple is disadvantageous with high water absorption and a decrease in color density with higher application weights

    Die JP 06-262845 A beschreibt ein Empfangsmaterial, bestehend aus einem Papierträger und einer Tintenaufnahmeschicht. Der Papierträger enthält Laubholz-Zellstoff und eine Leimung aus Stärke und Alkylketen-Dimer. Nachteilig ist auch hier das Auftreten einer Welligkeit des Trägermaterials durch den alleinigen Einsatz von Kurzfaserzellstoff.JP 06-262845 A describes a receiving material, consisting of a paper support and a Ink receiving layer. The paper backing contains hardwood pulp and a sizing of starch and alkyl ketene dimer. The occurrence of a is also disadvantageous here Waviness of the carrier material by the sole Use of short fiber pulp.

    Die EP 0 423 829 A betrifft ein Aufzeichnungsblatt für das Ink-Jet-Verfahren zur Aufnahme wäßriger Tinten und befaßt sich auch mit dem Problem des Cockle bei diesen Aufzeichnungsmaterialien. Was das Trägerpapier anbetrifft, schlägt diese Druckschrift einen gewissen Leimungsgrad sowie eine bestimmte Dehnung vor. Die US 5 320 897 offenbart ein Aufzeichnungsblatt für das Ink-Jet-Verfahren zur Aufnahme wäßriger Tinten und offenbart eine Zellstoffmischung aus 5 Teilen Nadelholzsulfatzellstoff und 95 Teilen Eukalyptuszellstoff zur Herstellung des Papierträgers. EP 0 423 829 A relates to a recording sheet for the ink jet process for taking up aqueous inks and also deals with the problem of the cockle with these Recording materials. As for the backing paper As for, this publication suggests a certain Degree of sizing as well as a certain stretch. The US 5th 320 897 discloses a recording sheet for the ink jet process for receiving aqueous inks and discloses one Cellulose blend of 5 parts of softwood sulfate pulp and 95 parts of eucalyptus pulp to make the Paper carrier.

    Der Anteil des Nadelholzsulfatzellstoffs beträgt 10% bis 40% vom Gesamtzellstoff. Diese Zusammensetzung hat sich als Vorteilhaft zur Erreichung einer hohen Dimensionsstabilität erwiesen. Zur Erhöhung der Weiße und Opazität können anorganische Pigmente wie Calciumcarbonat, Clay, Titandioxid und Silikate zugegeben werden. Die Ausrichtung der Fasern in Längs- und Querrichtung muß so gewählt werden, daß sich bei der Reißlänge und der Biegesteifigkeit ein Verhältnis längs/quer < 2,0 ergibt.
