Abstract
A drying assembly comprises a plurality of electromagnetic energy sources arranged to dry printing fluid deposited onto a surface of a substrate, by evaporation of a solvent fluid therefrom. The drying assembly further comprises a conveyor system configured to move the substrate in a conveying direction, and a focusing system configured to focus electromagnetic energy from the plurality of electromagnetic energy sources to form a non-uniform heating pattern on the surface of the substrate. The non-uniform heating pattern comprises a plurality of spatially separated higher and lower intensity regions distributed along the conveying direction.
