Summary:The present disclosure provides a transfer method to transfer a viscous functional material onto a receiving substrate. The method provides a plate (10) having a cavity surface (11) that includes a cavity (12). Furthermore it provides a plurality of individually addressable resistive heater elements (131, 132, 133) in thermal contact with respective zones (121, 122, 123) of the cavity (12). It provides viscous functional material (50) in the cavity with a material composition that, when sufficiently heated, generates a gas at an interface between the cavity surface in the cavity and the functional material, to transfer the functional material from the cavity by the gas generation onto the receiving substrate. According to the improved transfer method respective portions of the viscous functional material in respective zones of the cavity are heated by supplying respective ones of the plurality of individually addressable heater elements with an electric power (C131, C132, C133) having a respective time dependent magnitude.
