- a separate print template is created for each ink contains all elements that are printed in the respective color.
- these are the inks cyan, magenta, yellow and black (CMYK).
- CMLK cyan, magenta, yellow and black
- the artwork is usually printed on plates in a platesetter recorded, with which then in a printing press the printed pages be printed with high circulation.
- the artwork can be printed directly as digital data to a digital press. There will be the artwork data then, for example, with a in the printing press integrated exposure unit exposed on printing plates before immediately afterwards the print starts.
- a laser beam generated by a laser diode formed by optical means and on the Pressure plate focused and by means of a deflection system point and line by line distracted over the pressure plate.
- a bundle of laser beams can be generated, and with each sweep the printing plate are exposed several image lines simultaneously.
- the Printing plate can be on an exposure drum (external drum imagesetter), in a cylindrical trough (internal drum imagesetter) or on a flat surface Surface (flatbed platesetter).
- an external drum imagesetter the printing plate to be exposed on a rotatably mounted exposure drum assembled.
- the exposure drum As the exposure drum rotates, it becomes an exposure head moved axially along the drum at a relatively short distance. Of the Exposure head focuses one or more laser beams on the drum surface, which cover the drum surface in the form of a narrow helix. In this way, one or more turns every drum revolution Illuminated image lines.
- the leading edge of the printing plate is by mostly fixed plate clamps clamped, the trailing edge is through removable or adjustable clamps fixed.
- the names front edge or trailing edge are with respect to the direction of rotation of the exposure drum defined in the exposure, the laser beams the pressure plate at each Turn over the revolution beginning at the leading edge and ending at the trailing edge.
- the pressure plate often held with a vacuum device on the drum surface, which the Squeezes pressure plate through holes or grooves in the drum surface so that it is not replaced by centrifugal forces during rotation.
- EP 1 364 779 A2 describes an arrangement in which clamping devices for the leading edge and for the trailing edge of the printing plate of the same Actuator be actuated.
- the clamping devices for the leading edge exist in principle, of clamping levers whose pivots are above the drum surface are. One end of the clamping lever presses with the aid of a spring force on the front End of the pressure plate and clamps it by. With an actor on the free end of the clamping lever can be lowered, the clamping devices solved again.

- the known clamping devices in particular after the Klemmhebelkalin working constructions, have the disadvantage that they are considerably over protrude beyond the drum surface and also require actuators outside the exposure drum must be arranged. This will make the available Limited space for other subunits of the platesetter.
- the known disk clamps have a considerable mass, which they can bring an imbalance into the drum rotation, which in turn one Device for balancing the imbalance required.
- brackets or terminal strips for the trailing edge of the printing plate before that they also firmly place the pressure plate on the drum surface press.
- these terminals must also be movable, consuming mechanical devices required with which these terminals on the one hand can be locked at any circumferential position, on the other hand but also be solved again or completely removed.
- the printing plate on the exposure drum without clamping the disadvantages of the known clamping devices and to hold, with the clamping or holding means for the leading edge and for the trailing edge in particular protrude only very slightly beyond the drum surface should.
- the object is achieved by a clamping device for the front edge of the printing plate solved, whose actuators housed in the interior of the exposure drum are. Only the clamping bar, which the pressure plate to the drum surface Press, slightly protrude beyond the drum surface. Thereby No actuators are required for the operation of this clamping device, the are outside the exposure drum.
- the pressure plate are provided terminating elements which are in the vacuum grooves the drum surface can be moved and the primary cause that the negative pressure that sucks the pressure plate to the drum surface, on the area under the pressure plate is restricted.
- These finishing elements are additionally provided with a roof element, which over the trailing edge the pressure plate protrudes and thus the trailing edge in the space between Roof element and exposure drum locks. With the roof elements is the Pressure plate but not pressed to the drum surface, which is why no facilities needed, with which the end elements at their circumferential position would have to be locked.
- Fig. 1 shows the basic structure of a Popetrommelbelichters.
