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

A method for printing an image on a printing substrate comprising the steps of:

• producing a plurality of portions of fluid printing ink on a printing-ink carrier by inputting energy using a plurality of image spots of an array of individually controllable VCSEL light sources;
• and
• transferring the fluid printing ink to a printing substrate, wherein the input energy is produced by a device including the array, the array including subarrays of VCSEL bars, the printing-ink carrier having an axis of rotation and a surface for receiving the plurality of image spots of the laser light sources, rows of the image spots being inclined with respect to the axis of rotation when the VCSEL bars are triggered simultaneously.

A printing press for printing an image on a printing substrate comprising:

• a plurality of individually controllable laser light sources having a modular design including subarrays disposed in an array, the subarrays being VCSEL bars;
• and
• a printing-ink carrier having an axis of rotation and a surface for receiving a plurality of image spots of the laser light sources, rows of the image spots being inclined with respect to the axis of rotation when the VCSEL bars are triggered simultaneously, the light sources producing a plurality of portions of fluid printing ink on the printing-ink carrier by inputting energy using the plurality of image spots, the printing-ink carrier transferring the fluid printing ink to a printing substrate.
