KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Dem Weifsblech, welches bekanntlich mit Zinn belegt ist, moireeartiges (perlmutterähnliches) Aussehen zu geben, ist in Blechindustriekreisen ja bekannt, indem man blanke Weifsbleche oder andere verzinnte Bleche nach vorherigem Erhitzen in ein Aetzbad taucht oder | sie damit überwischt. Während dieses Vorganges bilden sich durchweg auf der ganzen Tafel Krystalle, Moiree genannt.The white sheet, which is known to be covered with tin, is moiré-like (mother-of-pearl) Giving appearance is known in sheet metal industry circles by making blank white sheet metal or immerses other tin-plated sheets in a caustic bath after prior heating or | wiped them over with it. During this process they consistently form all over the place Tafel Krystalle, called Moiree.
Die so hergestellten Tafeln wurden dann auf dem Wege des Blechdruckes decorirt; da aber der Moireegrund bei Figuren, Landschaften und besseren Plakaten theilweise störend und nicht passend wirkt, so mufste man die betreffenden Stellen mit Deckfarbe oder Bronze bedrucken, welche das Moiree aber oft nicht ganz verschwinden liefsen und eine beliebige Farbenzusammenstellung nicht zuliefsen.The panels produced in this way were then decorated by tin printing; here but the moiré reason in figures, landscapes and better posters is partly disturbing and doesn’t seem appropriate, you would have to cover the areas in question with covering paint or bronze print, which the moiré often did not disappear completely and any Color combination not allowed.
Der Zweck des nachstehend beschriebenen neuen Verfahrens ist, diese Uebelstände zu vermeiden, sowie gleichzeitig dadurch die Wirkung der Blechbuntdrucke in beliebiger Verwendung von Moiree zu erhöhen.The purpose of the new procedure described below is to remedy these evils Avoid, and at the same time thereby the effect of the tinplate prints in any Use moiré to increase.
Das Verfahren besteht darin, dafs man die Stellen des zu bedruckenden Bleches, auf welchen die Moireekrystallisation . nicht stattfinden soll, vor der Aetzung mit beliebigen lasirenden oder deckenden Blechdruckfarben bedruckt; die so behandelten Bleche werden im Trockenofen gut getrocknet. Nachdem dies geschehen und die als blank sichtbaren Stellen sauber sind, übergiefst oder Uberwischt man die theilweise bedruckte Tafel mit einer Mischung von verdünnter Salpeter- und Salzsäure oder Schwefelsäure, je nach der Stärke des Zinnes. Sobald nach einigen Secunden die Wirkung der Aetzflüssigkeit dem Auge sichtbar wird, spült man die Blechtafeln mit reinem Wasser ab; den eventuell gebildeten Aetzschaum entfernt man mittels eines weichen Schwammes.The method consists in that the points of the sheet to be printed on, on which the moire crystallization. should not take place before etching with any glaze or opaque tin printing inks; the sheets treated in this way are put in a drying oven well dried. After this has been done and the areas that are visible as blank clean are, doused or wiped over the partially printed board with a mixture of dilute nitric and hydrochloric acids, or sulfuric acid, depending on the strength of the tin. As soon as the effect of the caustic solution becomes visible to the eye after a few seconds, one rinses the sheet metal with pure water; any caustic foam that may have formed is removed using a soft sponge.
An der Stelle, wo die gewünschte Schutzschicht aufgedruckt war, hat sich eine Krystallisation nicht bilden können, und ist somit eine störende Wirkung vermieden.Crystallization has occurred at the point where the desired protective layer was printed can not form, and a disruptive effect is thus avoided.
Nunmehr kann mit dem weiteren Drucken der eventuell noch fehlenden Farben auf der1 ganzen Tafel begonnen werden.Now, the possibly still missing colors on the one whole panel can be started with the further printing.
