Patentirt im Deutschen Reiche vom 23. Januar 1894 ab.Patented in the German Empire on January 23, 1894.
Die Herstellung von lithographischen Druckplatten, insbesondere zu Chromoarbeiten, geschah bisher dadurch, dafs mittelst einer Stahlfeder und lithographischer Fetttinte mit der Hand Punkt an Punkt oder Linie an Linie auf den lithographischen Stein gezeichnet wurde, und zwar weiter oder dichter und mit dünneren oder dickeren Punkten bezw. Linien oder Strichen, je nach der malerischen Wirkung, welche der Lithograph erzielen wollte. Eine annähernde Wirkung ward auch dadurch erreicht , dafs mittelst Umdruckpapiers Uebertragungen von geeigneten Punkten oder Strichen auf den durch Abdeckung begrenzten Steinflächen erzeugt wurden. Sind diese beiden Arten indessen umständlich und zeitraubend, so sucht ein annäherndes Resultat auf maschinellem Wege ein complicirter Apparat zu erreichen , welcher Gegenstand des D. R. P. Nr. 17316 war, dessen umständliche Handhabung und beschränkte Verwendbarkeit indefs weit hinter dem angestrebten Ziele zurückblieb.The production of lithographic printing plates, especially for chromo work, happened hitherto by using a steel pen and lithographic grease ink with the Hand drawn point to point or line to line on the lithographic stone namely further or denser and with thinner or thicker points BEZW. Lines or Lines, depending on the painterly effect the lithographer wanted to achieve. One an approximate effect was also achieved by making transfers by means of transfer paper of suitable points or lines on the stone surfaces delimited by the cover were generated. If, however, these two types are cumbersome and time-consuming, look for an approximate result using a machine Ways to achieve a complex apparatus which was the subject of D. R. P. No. 17316, its cumbersome handling and limited usability, however, fell far short of the intended goal.
Die vorliegende Erfindung bezweckt nun, das vorgesteckte Ziel schnell und sicher zu erreichen dadurch, dafs ein System fiach- oder vollstempelartiger Druckformen, zur bequemeren Handhabung nöthigenfalls mit Handgriff versehen, aus einem geeigneten Material (Kautschuk) angefertigt wird, welche die Punkte, Linien, überhaupt alle diejenigen zeichnerischen Formen reliefartig enthalten, welche sonst mit der Hand auf den Stein gebracht wurden. Mittelst dieser Stempel werden nun jene Punkte oder Linien in breiteren oder kleineren Flächen auf den zu lithographirenden Stein oder die zu benutzenden Platten durch Stempelung mit Fettfarbe an den vorgesehenen Stellen übertragen und das Uebertragene, nachdem Mangelhaftes mit der Hand retouchirt worden war, ganz wie gewöhnliche Federarbeit behandelt.The present invention now aims to achieve the goal set quickly and safely achieve by using a system of flat or full stamp-like printing forms, for more convenient If necessary, handle it with a handle, made of a suitable material (rubber), which contains the points, Lines, in general, contain all those graphic forms in relief that are otherwise with were brought to the stone by hand. In the middle of these stamps, those points become or lines in wider or smaller areas on the stone or stone to be lithographed Transfer the plates to be used by stamping them with grease paint in the designated places and the transferred, after the defective had been retouched by hand, treated just like ordinary pen work.
Die Begrenzung der zu erzeugenden Druckflächen erfolgt entweder durch Abdeckung mit angesäuertem Gummi arabicum oder mittelst Auflegens von Papierpatronen, auf denen das Abzustempelnde durch Ausschneiden zuvor freigelegt worden war.The printing areas to be generated are limited either by covering them with acidified gum arabic or by placing paper cartridges on which the To be stamped had previously been exposed by cutting out.
