Abstract

Die Erfindung betrifft ein Verfahren zur Fixierung von Toner auf einem Träger bzw. einem Bedruckstoff, insbesondere einem blattförmigen Bedruckstoff, vorzugsweise für eine digitale Druckmaschine, daß dadurch gekennzeichnet ist, daß der Toner aufweisende Bedruckstoff mit Mikrowellen aus wenigstens einem Mikrowellensender bestrahlt und für das Schmelzen des Toners erhitzt wird und daß ein Toner verwendet wird, der einen starken Abfall des elastischen Moduls G' von seinem festen zu seinem flüssigen Zustand beim Erhitzen zeigt.The invention relates to a method for fixing toner on a support or a substrate, in particular a sheet-shaped substrate, preferably for a digital printing machine, characterized in that the toner containing toner is irradiated with microwaves from at least one microwave transmitter and for melting the Toner is heated and that a toner is used, which shows a strong decrease of the elastic modulus G 'from its solid to its liquid state when heated.

Vorzugsweise beträgt das Verhältnis des Wertes des elastischen Moduls G' des erfindungsgemäßen Toners bei dem Referenztemperaturwert, errechnet aus der Anfangstemperatur beim Beginn des Glasübergangs des Toners plus 50°C, zu dem Wert des elastischen Moduls G' bei der Anfangstemperatur selbst < 10-5.Preferably, the ratio of the elastic modulus G 'of the toner of the present invention at the reference temperature value calculated from the initial temperature at the start of the glass transition of the toner plus 50 ° C to the value of the elastic modulus G' at the initial temperature itself is <10 -5 .

Des weiteren betrifft die Erfindung eine Einrichtung zur Fixierung von Toner, vorzugsweise zur Durchführung des genannten Verfahrens, mit wenigstens einem Mikrowellen abgebenden Sender.Furthermore, the invention relates to a device for fixing toner, preferably for carrying out said method, with at least one microwave emitting transmitter.
