A compact device for imaging (10) a printing form (12), including a number of light sources (14) as well as imaging optics (18) for producing a number of image spots (16) of the light sources (14) on the printing form (12), the imaging optics (18) including at least one macro- optical system (20) of refractive optical components (32, 56, 58; 60, 62, 64), the imaging device having the feature that the optical path (22) from the light sources (14) to the image spots (16) passes through the macro-optics (20) twice. The installation-space saving imaging device (10) can be used in a printing unit (88) of a printing press (90).

Dispositif compact de création d'image (10) sur une forme d'impression (12) doté d'un certain nombre de sources lumineuses (14) et d'une optique d'imagerie (18) pour produire un certain nombre de points d'image (16) provenant des sources lumineuses (14) sur la forme d'impression (12). L'optique d'imagerie (18) comprend au moins un système macrooptique (20) de composants optiques réfringents (32, 56, 58; 60, 62, 64). Le dispositif d'imagerie a comme caractéristique un trajet optique (22) partant des sources lumineuses (14) et allant aux points d'image (16) en passant deux fois par le système macrooptique (20). Le dispositif d'imagerie peu encombrant (10) peut être utilisé dans une unité d'impression (88) d'une presse d'imprimerie (90).
