Description

  

  Verfahren zum     Troeknen    von Reproduktionen, für     welehe    fett-     bezw.          ölfirnislialtige    Farben verwendet worden.    Farben, die in der allgemeinen     Druck-          und    Reproduktionstechnik zur Verwendung  kommen, enthalten Fettzusätze, nämlich Öle,  Firnisse oder dergleichen. Dem Verfahren       angepasst,    werden mehr oder weniger solcher  n  Fette den Farben beigemischt. Die fett  haltigen -Farben beeinträchtigen naturgemäss  das Trocknen der Reproduktionen, was aus  verschiedenen Gründen als nachteilig be  zeichnet werden darf.

   So ist es     beim.Mehr-          farbendruck    beispielsweise Bedingung,     dass     jeweils die vorher aufgetragene Farbe einen       ()-    Wissen Grad von Trockenheit erreicht  haben     muss.     



  Wohl sind     sogenannte    Trockenmittel be  kannt, die den Farben beigemischt werden  können. Diese Mittel sind aber nicht durch  wegs als vollwertig<B>zu</B> bezeichnen, denn     sol-          eben    Verfahren haften zum Beispiel die  Nachteile an,     dass    die Farben auch auf den       Auftragwalzen    einem schnellen     #    Trocknen  ausgesetzt sind. Zur Trocknung wird in  neuerer Zeit auch ein Verfahren angewendet,    gemäss welchem geschmolzenes Paraffin oder  dergleichen auf die Reproduktion aufgetra  gen wird. Ein weiteres bekanntes Mittel be  steht darin,     dass    die Abzüge mit Talkum,  Bronze oder dergleichen eingestäubt werden.

    Diese Staubgebilde haften aber nur an der  Oberfläche     d2r    aufgetragenen Farbe, ohne       dass    aber die Farben     rasclier    trocknen. Sie  dienen nur zum     Scliuize    dafür,     dass    aufein  ander gelegte Reproduktionen nicht anein  ander haften.  



  Gegenstand vorliegender Erfindung ist  ein Verfahren zum Trocknen von Reproduk  tionen, für welche fett-     bezw.    ölhaltige Far  ben verwendet werden, gemäss welchem die  Lösung eines     Zellulosederivates    auf die Re  produktion aufgebracht wird.  



  Als     Zelluloselack    kann zum Beispiel     Za-          ponlach,    verwendet werden. Derselbe kann  manuell oder auf mechanischem Wege auf  die Reproduktion aufgebracht werden oder  dieselbe kann in die Lacklösung eingetaucht  werden. Nach dem Aufbringen des Lackes      auf die Reproduktionen kann vermittelst  Wärme getrocknet werden.



  Method for drying reproductions, for welehe bold or. Oil-varnished colors have been used. Inks that are used in general printing and reproduction technology contain fat additives, namely oils, varnishes or the like. Depending on the process, more or less such fats are added to the colors. The fat-containing colors naturally impair the drying of the reproductions, which for various reasons can be described as disadvantageous.

   In the case of multi-color printing, for example, it is a condition that the previously applied color must have reached a certain level of dryness.



  So-called desiccants are known that can be mixed with the colors. However, these agents cannot be described as fully <B> to </B> because such methods have the disadvantages, for example, that the inks are also exposed to rapid drying on the applicator rollers. Recently, a method has also been used for drying according to which molten paraffin or the like is applied to the reproduction. Another known means is that the prints are dusted with talc, bronze or the like.

    However, these dust structures only adhere to the surface of the applied paint, without the paint drying as a razor. They only serve to ensure that reproductions that are placed on top of one another do not adhere to one another.



  The present invention is a method for drying reproductions for which fett- BEZW. Oil-based colors are used, according to which the solution of a cellulose derivative is applied to the reproduction.



  Zaponlach, for example, can be used as cellulose varnish. It can be applied to the reproduction manually or mechanically, or it can be immersed in the lacquer solution. After the lacquer has been applied to the reproductions, heat can be used to dry it.
