  Verfahren, um Aluminiumblech zum Beschreiben und Bedrucken geeignet zu   machen.   



   Es sind verschiedene Verfahren vorgeschlagen worden, um Aluminiumblech zum Beschreiben und Bedrucken geeignet zu machen. Es wurde zu diesem Zwecke namentlich eine Entfettung und Beizung des Aluminiums vorgenommen oder es wurde auch die Oberfläche mit feinen Bürsten aufgerauht. 



   Die auf so hergestellten Aluminiumblechen ausgeführten Drucke und Schriften sind nie ganz rein oder verwischen sich doch leicht, wenn sie oftmalig mit vielleicht nicht ganz trockenen Händen angefasst werden, wie es beispielsweise bei Speisekarten in Gasthäusern der Fall ist. 



   Gemäss der Erfindung wird nun das Aluminiumblech, nachdem es gegebenenfalls durch Abbeizen oder insbesondere durch Bürsten mit Benzin, Seife u. dgl. gereinigt ist, mit   einem Überzüge   von Eiweiss versehen. Auf diesem Eiweissüberzug, der aus   Hühnereiweiss,   Blutalbumin, Kasein usw. bestehen kann, hält jede Farbe sehr gut und lassen sich auch Drucke im Offset-Verfahren herstellen. 



   Auch die Verwendung von Wasserfarben ist möglich, weil dieselben durch das Eiweiss gebunden werden und dann durch Behandeln mit irgendeinem bekannten Härtungsmittel des Albumins, z. B. 



  Formalin, gehärtet und unlöslich gemacht werden können. 



   Auf diese Weise lassen sieh auch Zeichnungen oder Schriftzeichen herstellen, welche in Alkohol   unverwischbar   sind, während gewöhnliche Tinte oder Bleistiftschriftzeichen sich damit von der ungehärteten oder gehärteten Eiweissschichte vollständig abwaschen lassen.

  Process to make aluminum sheet suitable for writing and printing.



   Various methods have been proposed to make aluminum sheet suitable for writing and printing. For this purpose, the aluminum was degreased and stained, or the surface was roughened with fine brushes.



   The prints and writings on aluminum sheets produced in this way are never completely pure or are easily blurred if they are often touched with perhaps not completely dry hands, as is the case, for example, with menus in inns.



   According to the invention, the aluminum sheet, after it has been removed by stripping or, in particular, by brushing with gasoline, soap and the like Like. Is cleaned, provided with a coating of protein. On this protein coating, which can consist of chicken protein, blood albumin, casein, etc., any color holds very well and prints can also be made using the offset process.



   The use of watercolors is also possible because they are bound by the protein and then treated with any known hardening agent of the albumin, e.g. B.



  Formalin can be hardened and made insoluble.



   In this way, you can also make drawings or characters that are indelible in alcohol, while ordinary ink or pencil characters can be completely washed off the uncured or hardened protein layer.
