Abstract
Verfahren zur Vorbeschichtung von nicht saugfähigen Trägern, insbesondere aus Kunststoffen, Metallen oder Glas, für den Tintenstrahldruck mit wasserbasierter Tinte und Druckvorrichtung, wobei die Vorbeschichtung mit einer polyfunktionellen Carbonsäure erfolgt.Process for the precoating of non-absorbent carriers, in particular of plastics, metals or glass, for inkjet printing with water-based ink and printing apparatus, wherein the precoating is carried out with a polyfunctional carboxylic acid.
Description
Die Erfindung betrifft ein Verfahren zur Vorbeschichtung von nicht saugfähigen Trägern, insbesondere aus Kunststoffen, Metallen oder Glas, für den Tintenstrahldruck mit wasserbasierter Tinte und eine Druckvorrichtung.The The invention relates to a method for precoating non-absorbent carriers, in particular of plastics, metals or glass, for inkjet printing water-based ink and a printing device.
Beim Bedrucken der eingangs genannten Träger – insbesondere Karten – im Tintenstrahldruck mit wasserbasierter Tinte ergeben sich wenig zufriedene Druckbilder, beispielsweise, da die Tinte verfließt oder nicht richtig haftet.At the Printing the aforementioned carrier - in particular cards - in inkjet printing with Water-based ink result in little satisfied printed images, for example, because the ink is leaking or does not adhere properly.
Die Lösung dieses Problems ist die Aufgabe der Erfindung. Das gattungsgemäße Verfahren und die Druckvorrichtung sollen so weiter entwickelt werden, dass auf einfache Weise ein verbessertes Druckbild erzielt wird.The solution This problem is the object of the invention. The generic method and the printing device should be further developed so that in a simple way an improved print image is achieved.
Die Erfindung löst diese Aufgabe durch das Verfahren des Anspruchs 1 und die Druckvorrichtung des Anspruchs 6.The Invention solves This object is achieved by the method of claim 1 and the printing device of Claim 6.
Vorteilhafte Ausgestaltungen sind den Unteransprüchen zu entnehmen.advantageous Embodiments are to be taken from the subclaims.
Erfindungsgemäß wird das Druckbild auf einfache Weise deutlich verbessert. Die erfindungsgemäße Technologie ermöglicht es, auf verschiedenen Materialien mit wasserbasierenden Inkjettinten zu drucken. Die Bedruckung kann insbesondere 4-farbig ohne ein Verlaufen der Tinten vorgenommen werden. Dazu wird das zu bedruckende Material im Drucker (besonders vorteilhaft) oder vorab separat vorbeschichtet.According to the invention Print image improved in a simple way. The technology of the invention allows it, on different materials with water-based inkjettinten to print. The printing can in particular 4-colored without a bleeding of the inks be made. For this, the material to be printed in the printer (particularly advantageous) or pre-coated separately in advance.
Als Beschichtungsmaterial hat sich überraschenderweise Citronensäure in Pulverform besonders bewährt.When Coating material has surprisingly citric acid especially proven in powder form.
Besonders vorteilhaft ist das Aufbringen der Beschichtung direkt im Drucker.Especially advantageous is the application of the coating directly in the printer.
Nachfolgend wird die Erfindung unter Bezug auf die Zeichnung näher beschrieben. Es zeigen:following the invention will be described in more detail with reference to the drawing. Show it:

Die Beschichtung ist in Pulverform oder in flüssiger Form aufbringbar.The Coating can be applied in powder or liquid form.
Denkbar ist insbesondere ein Flüssigauftrag der Beschichtung mittels Schwamm oder Sprühkopf.Conceivable is in particular a liquid application of Coating by sponge or spray head.
Vorteilhaft sind auch eine abschließende Bürste oder eine Absaugstation zum Entfernen restlicher Vorbeschichtung.Advantageous are also a final brush or a suction station for removing residual pre-coating.
Es konnte bei einem Versuch, bei dem eine Vorbehandlung der Oberfläche mit Citronensäure in Pulverform durchgeführt wurde, die Tinte zeitlich und örtlich im Verlauf(en) begrenzt und anschließend thermisch induziert polymerisiert (ausgehärtet) werden.It could in an attempt at which a pretreatment of the surface with citric acid carried out in powder form became, the ink temporally and locally limited in course (s) and then thermally induced polymerized (hardened) become.
Die
Vorbehandlung erfolgte durch Aufstreichen/Einreiben mit einen Tuch
auf einen kartenförmigen
Träger
(nicht saugfähiges,
strukturiertes Substrat) mit einem anschließenden Entfernen losen Pulvers
durch Pusten/Wischen. Die Beschriftung der Karten wurde mittels
Tintendruck vorgenommen, genutzt wurde ein Tintenstrahldruck mit
Tinte im PrintJet
Es ist auch vorteilhaft, wenn der Träger eine (regelmäßig) strukturierte Oberfläche aufweist. Derart sind Materialien wie Aluminium, Messing, Stahlblech, Edelstahl... (und andere) bedruckbar.It is also advantageous if the carrier has a (regularly) structured surface. Of the Materials such as aluminum, brass, sheet steel, stainless steel ... (and others) are printable.
Mögliche Schritte
der chemischen Reaktion sind in
Schritt 1: Die polyfunktionelle Carbonsäure (Citronensäure) haftet aufgrund der intermolekularen Kräfte der Dipol-Dipol Wirkung der funktionellen Gruppen mittels Wasserstoffbrückenbindung an den Peptidgruppen der Polyamidoberfläche. Die Carbonsäure vervielfacht dabei die Anzahl der funktionellen Gruppen auf der Oberfläche des zu bedruckenden Materials und stellt so für die Haftung der Tinte zusätzliche sehr reaktionsfähige, polare Stellen zur Verfügung.step 1: The polyfunctional carboxylic acid (citric acid) adheres due to the intermolecular forces the dipole-dipole effect of the functional groups by hydrogen bonding at the peptide groups of the polyamide surface. The carboxylic acid multiplies while the number of functional groups on the surface of the to print material, thus adding to the adhesion of the ink very reactive, polar sites available.
Schritt 2: Bestandteile der Tinte binden sich an die funktionellen Gruppen der Polycarbonsäure und an nicht besetzte, funktionelle Gruppen des Polyamids.step 2: Ingredients of the ink bind to the functional groups the polycarboxylic acid and unoccupied, functional groups of the polyamide.
Schritt 3: Darüber hinaus sorgt der pKs-Wert der aufgebrachten Polycarbonsäure für eine pH-Wert-abhängige Verdickung der Tinte und setzt eine chemische Aushärtungsreaktion in Gang.step 3: Above In addition, the pKs value of the applied polycarboxylic acid ensures a pH-dependent thickening the ink and sets in motion a chemical curing reaction.
