Abstract

The claim of the invention relates to the use of light-transmitting paper, called glassine (glassoid, pergamyne, imitation parchment), in conjunction with thermographic copying methods which operate in the spectral range, for the production of graphic arts.

Description

Die Erfindung beruht auf dem bekannten Prinzip leitender Fasern, die Licht oder Flüssigkeit absorbieren und transportieren. Stoffe aus Zellulose, Pergamin genannt, sind halbdurchlässige Papiere, die einen hohen Grad an Absorbtionsfähigkeit besitzen und die den Vorteil haben, lichtdurchlässig zu sein.The invention is based on the known principle of conductivity Fibers that absorb and transport light or liquid. Cellulose fabrics, called glassine, are semi-permeable Papers that have a high degree of absorbency and which have the advantage of being translucent.

Innerhalb graphischer Betriebe wird dieser Stoff Pergamentfolie genannt und dient zur Herstellung von Zeichenschablonen, die im weiteren Verlauf vervielfältigt werden.Within graphic factories, this material becomes parchment film called and is used for the production of stencils, which in further course can be reproduced.

Die Verbesserung der Kopierfähigkeit von graphischen Vorlagen ist ein bekanntes Anliegen der Forschung.The improvement of the copying ability of graphic originals is a well-known concern of research.

Die Neuerung besteht bei der Erfindung in der Beobachtung, daß bei der Verwendung von graphischen Vorlagen auf Pergamin zur Herstellung von Vervielfältigungen besonders gute Ergebnisse bei thermographischen Kopiergeräten, die im Spektralbereich arbeiten, erzielt werden. Ein Teil des auf die Vorlage fallenden Lichts wird durch die Lichtleitfähigkeit der Zellfasern absorbiert und durch eine hellweiße Auflage zurückreflektiert um wiederum absorbiert zu werden und die Farbe von der Rückseite zu durchdringen.The innovation in the invention is the observation that in the Use of graphic templates on glassine for the production of reproductions particularly good results in thermographic Copiers that work in the spectral range can be achieved. Part of the light falling on the original is emitted by the Light conductivity of the cell fibers is absorbed and by a bright white edition reflected back to be absorbed again be and penetrate the color from the back.

Die sogenannte Interferenz, die dabei entsteht, führt bekanntlich dazu, daß die Lichtwirkung sich teilweise abschwächt und stellenweise verstärkt.As is known, the so-called interference that results in that the lighting effect weakens partially and in places reinforced.

Das hat zur Folge, daß die Halbtonwerte, deren Wiedergabe meistens unnatürlich erscheinen, eine größere Plastizität und Farbdichte erhalten.As a result, the halftone values, their reproduction mostly appear unnatural, get greater plasticity and color density.

Deshalb besteht der Fortschritt bei dieser Erfindung darin, Papier, das lichtdurchlässig ist, als Vorlagenpapier für Original- Künstlergraphiken mit begrenzter Stückzahl im thermographischen Kopierverfahren in Verbindung mit Pigmenten wie z. B. Kadmium, Chrom, Eisenoxydfarben mit wasserlöslichen Bindern zu verwenden.Therefore, the advance in this invention is paper, which is translucent, as template paper for original Artist graphics with limited numbers in thermographic Copying process in connection with pigments such. B. cadmium, chromium, Use iron oxide paints with water-soluble binders.

Im Gegensatz zu anderen Flachdruckverfahren, die auf dem Prinzip der Unvermischbarkeit von Öl und Wasser beruhen, wird ein Arbeitsschritt benötigt den jeder ausführen kann, um von der Originalvorlage zur Vervielfältigung zu gelangen.In contrast to other planographic printing processes, which are based on the principle based on the immiscibility of oil and water Work step required that everyone can perform to get from the Original artwork to be reproduced.
