Abstract

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).

Claims (25)

1. A 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), wherein the optical path (22) from the light sources (14) to the image spots (16) passes through the macro-optics (20) twice.
2. The device for imaging (10) a printing form (12) as recited in Claim 1, wherein the optical path (22) is off-axis.
3. The device for imaging (10) a printing form (12) as recited in Claim 1 or Claim 2, wherein the optical path (22) runs symmetrically to the optical axis (24) of the macro-optics (20).
4. The device for imaging (10) a printing form (12) as recited in one of the preceding claims, wherein the first principal plane (26) and the second principal plane (28) of the macro-optics are located on one side of the macro-optics (20).
5. The device for imaging (10) a printing form (12) as recited in one of the preceding claims, wherein at least one mirror (30) is associated with the macro-optics (20).
6. The device for imaging (10) a printing form (12) as recited in Claim 5, wherein the macro-optics (20) includes at least one part that is designed as an adaptive optic; or at least one mirror (30) is designed to be adaptive.
