    Abstract: A system (10, 110) includes: (i) a flexible intermediate transfer member (ITM) (44, 500, 600), including: a stack of: (a) a first layer (602), located at an outer surface of the ITM (44, 500, 600), configured to receive ink droplets to form an ink image thereon, and to transfer the ink image to a target substrate (50, 51), and (b) a second layer (603) including a matrix holding particles (622), configured to receive optical radiation (99) passing through the first layer (602), and to heat the ITM (44, 500, 600) by absorbing the optical radiation (99); (ii) an illumination assembly (113), configured to dry the ink droplets by directing the optical radiation (99) to impinge on the particles (622); and (iii) a temperature control assembly (121), configured to control a temperature of the ITM (44, 500, 600) by directing a gas (101) to the ITM (44, 500, 600).
