| 13. A printing system comprising:
a printhead array comprising a plurality of ink jet print heads for depositing a printing fluid onto a substrate to form images
on the substrate; and
a source which emits pulsed UV radiation to polymerize the printing fluid deposited onto the substrate by the plurality of
ink let print heads, wherein an energy level of the radiation emitted by the source is adjustable by varying the pulse rate
of the source, wherein the fluid is first set and subsequently cured, wherein the source comprises one or more setting sources,
each setting source being capable of setting the fluid and being positioned adjacent to a respective series of print heads,
the source further including a curing source capable of curing the fluid, the curing source being positioned at a trailing
end of the array of print heads and the setting energy sources.
