Claim 14:
15. A printing method for selectively modifying particles of a radiation modifiable material coating an imaging surface of a member, the method comprising:
a) moving the member relatively to a writing module, wherein the writing module is configured to direct onto the imaging surface a plurality of individually controllable light beams that are spaced from one another in a direction traverse to the direction of movement of the imaging surface, incidence of a light beam on a spot on the imaging surface serving to modify the particles of the radiation modifiable material carried by the imaging surface at the spot, the writing module comprising a plurality of integrated electronic modules each having an array of individually controllable light sources, each light source producing a respective one of the light beams comprising a cascade of at least two Vertical-Cavity Surface-Emitting Laser (VCSEL) light-emitting semiconductor junctions connected in series with one another and configured to emit light along a common axis so as to direct a single beam onto a single spot on the imaging surface, and
b) displacing the member having spots of irradiation modified material to at least one processing station selected from:
i. a transfer station, wherein the method comprises transferring the irradiation modified material spots from the imaging surface to a printing substrate;
ii. a direct embellishment station, wherein the method comprises applying embellishment particles to the irradiation modified material spots on the imaging surface;
iii. an indirect embellishment station, wherein the method comprises applying embellishment particles to the irradiation modified material spots transferred from the imaging surface to a printing substrate at a transfer station; and
iv. a finishing station located downstream from the last of a transfer station, a direct embellishment station and an indirect embellishment station, with respect to a direction of displacement, wherein the method comprises applying finishing steps to the printing substrate.
