Abstract

Verfahren zum Ansteuern eines nach dem Thermotransferprinzip arbeitenden Druckkopfes (102.1) mit mehreren Druckelementen (102.3), bei dem in einem Zufuhrschritt einem Druckelement (102.3) eine Energiemenge zugeführt wird, um Farbe von einer dem Druckkopf (102.1) zugeordneten Farbträgereinrichtung (103) auf ein der Farbträgereinrichtung (103) zugeordnetes Substrat (104) zur Erzeugung eines Bildpunktes eines Barcodes (104.2) zu transferieren, wobei die Energiemenge in Abhängigkeit von der Lage des Bildpunktes in dem Barcode (104.2) eingestellt wird.

Figure imgaf001
A method of driving a thermal transfer print head (102.1) having a plurality of printing elements (102.3) in which a quantity of energy is supplied to a printing element (102.3) in a feed step to transfer color from a ink carrier (103) associated with the print head (102.1) the substrate (104) associated with the ink carrier device (103) for generating a pixel of a bar code (104.2), wherein the amount of energy is set as a function of the position of the pixel in the bar code (104.2).
