Abstract
The invention relates to a laser based printing apparatus (100) using laser light sources (111, 112, 113, 402, 404, 406, 604, 606, 808, 810) for supplying energy to a target object (120) to form an image. The printing apparatus (100) comprises a laser light source arrangement (110, 400, 600) comprising a plurality of laser light sources (111, 112, 113, 402, 404, 406, 604, 606, 808, 810) arranged such that laser beams (114, 410, 805, 806) of the laser light sources (111, 112, 113, 402, 404, 406, 604, 606, 808, 810) intersect a surface (121) of a target object (120) at different target points (123, 24, 125, 412, 414, 416, 616, 610, 802) along a moving direction (122), a transport mechanism (130) for moving the target object (120) and the laser light sources (111, 12, 113, 402, 404, 406, 604, 606, 808, 810) relatively to each other in the moving 10 direction (122) and a controlling arrangement (140), which is realized to control the laser light sources (111, 112, 113, 402, 404, 406, 604, 606, 808, 810) and/or the transport mechanism (130) based on image data (150) in such a way, that the energy level of a target point (123, 124, 125, 412, 414, 416, 616, 610, 802) is stepwise increased…
