Printing apparatus

A printing apparatus, comprising:

• a discharging head configured to discharge ultraviolet-curable ink at a printable medium;
• a relative movable assembly configured to move the printable medium and the discharging head relatively in a predetermined direction when the discharging head discharges the ink at the printable medium;
• and
• a lighting unit including a plurality of light sources configured to emit light for curing the ink, the plurality of light sources including a part of the plurality of light sources and another part of the plurality of light sources, wherein:
• the part of the plurality of light sources is arranged in a first lighting area,
• the another part of the plurality of light sources is arranged in a second lighting area,
• a quantity of the light sources per unit area in the second lighting area is smaller than a quantity of the light sources per unit area in the first lighting area, and
• a direct distance from the discharging head to the second lighting area in a direction parallel to the predetermined direction is shorter than a direct distance from the discharging head to the first lighting area in the direction parallel to the predetermined direction.
