Abstract (en)
The invention relates to a process for printing by heat transfer using a printing head comprising a line of heating points. It also relates to an electronic control device enabling this process to be implemented. The process consists in applying heating current pulses according to a defined heating cycle to N lines of printing and in reversing this cycle every N lines. Application to thermal printing (thermo-printing), especially on plastic media (supports). <IMAGE>
