The new thermal paper Oekobon is build up from a first-class base paper from sustainable forestry. Oekobon has been developed particularily for this innovative technology of thermal printing.
The thermoactive layer is sensitive to the heat of the thermal print head. Other than standard thermal papers, it contains small bubbles which collapse by the heat of the print head during heat transfer. By this purely physical reaction the black colour layer becomes visible and results in printing the image spot. This makes the printed image on the receipt.
