| 摘要 |
The invention relates to a method for triggering an exposure device for the photomechanical production of structured surfaces as a copy of an electronically memorized model, in particular for exposing printing plates, in which the exposure device includes at least one light source (3), one picture generating unit (8) comprising movable, electronically individually triggerable micro mirrors arranged in a grid, and one copying optical element (9). To shorten the total exposure time without a loss of quality, it is provided that the model is broken down electronically into two-dimensional partial images; that the partial images are shown in succession, but each partial image is shown with its entire area at the same time, by means of the picture generating unit (8), and successive partial exposures of the surface to be structured are made, in that a exposure head (1), provided with the light source (3), the picture generating unit (8) and the copying optical element (9), moves between each two partial exposures from one exposure position to the next and stops there for the exposure, so that the individual partial copies are combined again into a total copy of the electronically memorized model.
