  Verfahren zur Herstel lung autotypischer Negative. 



   Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung autotypischer Negative, bei welchen die Belichtung durch zwei   verschiedonn   Raster erfolgt, von denen der eine ein   gowöhnlicber Krenzraster   ist,   ähnlich   wie bei dem Verfahren bekannter Art.

 sondern den   Tonreielhtnm   wesentlich zu   vergrössern.   



   Der wesentliche Unterschied   gegenüber bekannter Verfahren   ist in der besonderen Art des zweiten Rasters begründet, welcher anstatt regelmässig gedeckter und ungedeckter 
 EMI1.2 
 
Die kleinen gedeckten Elemente des Rasters sind an den Stellen angeordnet, wo die EckpunktevonvierbenachbartengrossenElementendieEckeneineskleinenQuadrates bilden. 



   Die Anzahl der gedeckten Elemente ist demnach doppelt so gross, wie bei dem bekannten Raster. 



   Das Resultat bei Anwendung dieses   Rasers in Verbindung   mit einem gewöhnlichen,   dem Linienverbaltnis   angepassten   Kreuzraster   ist infolge der enthaltenen doppelten Anzahl von verschiedenen grossen gedeckten Elementen ein vollständig anderes, indem ein wesentlich grösserer Tonreichtum im Bilde erzielt wird.

  Process for the production of autotypical negatives.



   The present invention relates to a method for the production of autotypical negatives, in which the exposure is carried out through two different grids, one of which is a conventional crown grid, similar to the method of the known type.
 EMI1.1
 but to increase the pitch range significantly.



   The main difference compared to known methods is due to the special type of the second grid, which instead of regularly covered and uncovered
 EMI1.2
 
The small covered elements of the grid are arranged in the places where the corner points of four adjacent large elements form the corners of a small square.



   The number of covered elements is therefore twice as large as with the known grid.



   The result of using this razor in connection with an ordinary cross raster adapted to the line arrangement is completely different due to the double number of different large covered elements it contains, in that a much greater tonal richness is achieved in the picture.
