Method for printing an image on a printing substrate and device for inputting energy to a printing-ink carrier

摘要

A method for printing an image on a printing substrate, a number of portions of fluid printing ink being produced on a printing ink carrier ( 10 ) through energy input by a number of image spots ( 810 ) of an array ( 84 ) of individually controllable VCSEL light sources, and the fluid printing ink being transferred to the printing substrate. A device for inputting energy ( 80 ) to a printing-ink carrier ( 10 ), includes a number ( 82 ) of individually controllable laser light sources which have a modular design consisting of subarrays ( 86 ) and are disposed in an array ( 84 ), and further includes printing-ink carrier ( 10 ) with which is associated an axis of rotation ( 88 ) and on the surface of which can be produced a number of image spots ( 810 ) of the laser light sources. The subarrays of laser light sources are VCSEL bars ( 84 ), and rows of image spots ( 12 ) of the VCSEL bars are inclined with respect to the axis of rotation ( 88 ).
