A very similar indirect printing process to direct thermal printing, where a heat sensitive ribbon replaces the heat sensitive thermal paper. Very smooth and receptive conventional. Paper or a suitable film is printed by means of an electronically controlled printing head which transfers variable data including bar codes to the label face material via a heat sensitive printer ribbon placed between the printing head and the face material. ribbon Thermal transfer, having indefinite longevity and superior durability, has been widely preferred for industrial bar coding and longer term applications.
To ensure the optimum thermal transfer printing quality it is vital to choose a ribbon that matches the thermal print head type, with the performance requirements of the label application and label surface.
