Description

Verfahren zur Verringerung der Durchscheinbarkeit und zur Erhöhung der Helligkeit von Druckpapier Es ist bekannt, Papier o. dgl. mit Farbstreifen oder Farbenrastern in verschiedenen Farben zu bedrucken, derart, daß diese Raster oder Farben so geringe Breite haben, daß sie ineinander übergehende Farben, beispielsweise Grau, liefern. Wenn nun derartige Flächen bedruckt werden, werden einige Bestandteile der Farben ausgeschaltet, während andere sichtbar bleiben. Die Färbung hängt dabei stets von der Art und Weise des Aufbringens der Schriftzeichen ab.Method of reducing translucency and increasing it the brightness of printing paper It is known, paper o. The like. With color stripes or Color grids to be printed in different colors, such that these grids or Colors have such a small width that they merge colors, for example Gray, deliver. When such surfaces are now printed, some components become of the colors are switched off, while others remain visible. The color depends on it always depends on the way in which the characters are applied.

Derartig bearbeitete Papiere lassen sich selbstverständlich allgemein für das Bedrucken beispielsweise von Zeitungen, Büchern o. dgl. nicht verwenden, da der Druck stets farbig erscheinen würde und je nach dem Farbton des aufgebrachten Rasters auch die unbedruckten Teile des Papiers farbig erscheinen werden.Papers processed in this way can of course be generalized do not use for printing newspapers, books or the like, for example, because the print would always appear in color and depending on the shade of the applied Raster, the unprinted parts of the paper will also appear colored.

Der Zweck der Erfindung ist nun, ein Verfahren zur Verringerung der Durchscheinbarkeit und zur Erhöhung der Helligkeit von Druckpapier zu schaffen, und zwar besteht das neue Verfahren darin, daß das Papier mit einem feinen Raster in einer die Farbe des Papiers reinweiß belassenden oder zu reinweiß ergänzenden Farbe bedruckt wird.The purpose of the invention is now to provide a method for reducing the To create translucency and to increase the brightness of printing paper, namely, the new method is that the paper with a fine grid in one that leaves the color of the paper pure white or complements it with pure white Color is printed.

Erreicht wird hierdurch, daß das behandelte Papier eine beträchtlich geringere Durchscheinbarkeit aufweist als das unbehandelte Papier, so daß ein wesentlich dünneres und leichteres Papier ohne Nachteil verwendet werden kann. Außerdem erscheint dem Auge das behandelte Papier heller als das unbehandelte. Zur Durchführung des Verfahrens nach der Erfindung kann die Oberfläche des Papiers mit Hilfe bekannter Maschinen mit einem z. B. schachbrettartigen Raster bedruckt werden, indem also zwischen den Rasterflächen gleichmäßig verteilte freie Flächen belassen werden.What is achieved hereby is that the treated paper has a considerable has less translucence than the untreated paper, so that a significant thinner and lighter paper can be used without any disadvantage. Also appears the treated paper is lighter to the eye than the untreated. To carry out the Method according to the invention can be the surface of the paper using known Machines with a z. B. be printed checkerboard grid by so Evenly distributed free areas are left between the grid areas.

Die Anordnung des Rasters braucht nicht schachbrettartig zu sein, da andere Anordnungen von gleichmäßig verteilten Punkten, Flecken, Vierecken, Figuren, Linien o. dgl. den Anforderungen des neuen Verfahrens genügen, solange die Anordnung so erfolgt, daß zwischen den aufgedruckten Rastern freie Flächen in gleichmäßiger Verteilung verbleiben.The arrangement of the grid does not have to be like a checkerboard, since other arrangements of evenly distributed points, spots, squares, figures, Lines or the like meet the requirements of the new method, as long as the arrangement takes place in such a way that free areas between the printed grids are more even Distribution remain.

Wesentlich für die Zwecke der Erfindung ist es, daßdiereflektierenden Rasterflächen derartige Abmessungen haben, daß sie sich bei Betrachtung vermischen und einzeln nicht sichtbar sind.It is essential for the purposes of the invention that the reflective Grid areas have such dimensions that they mix when viewed and are not visible individually.

Ein derartig behandeltes Papier erscheint dem bloßen Auge weißer als unbehandeltes Papier, trotzdem seine Durchscheinbarkeit wesentlich verringert ist. Die Oberflächenreflexion verbleibt reinweiß, so daß trotz der Verringerung der Menge des durchgelassenen Lichtes der Anschein einer reinweißen Fläche erweckt wird.Paper treated in this way appears whiter than to the naked eye untreated paper, although its transparency is significantly reduced. The surface reflection remains pure white, so that despite the reduction in the amount the transmitted light creates the appearance of a pure white surface.

Das Papier kann nach dem neuen Verfahren vollkommen fertig bearbeitet und dann wie jedes gewöhnliche andere Papier bedruckt werden, ohne daß besondere Arbeitsgänge, Einrichtungen oder Behandlungsverfahren Anwendung finden müssen.The paper can be completely finished using the new process and then printed like any other ordinary paper, without any special Operations, facilities or treatment processes must be used.
