Method for improving printing quality with a thermal transfer print head and assembly to carry out the method

摘要

The method is for quality improvement of printing with a thermotransfer printing head, wherein in one improvement step (30) an energy value calculation is carried in a manner according to which data of the image from a microprocessor is processed in order to also control those heating elements which lie in at least one of the edge regions of the heating element row, but where no dots are to be printed during printing of a barcode. Those heating elements which do not lie in the two edge regions of the heating element row are controlled by a heating impulse for a limited period of time. An independent claim is included for an arrangement for carrying out the method, wherein a high-resolution thermotransfer printing head has a row of heating elements, and a microprocessor evaluates energy values before the printing process to control the heating elements.
