Definitions
- the invention relates to a
- the invention relates to a corresponding computer program product or a corresponding method.
- the main area of application is the printing industry, where the transfer of data to data carriers, in particular the exposure of information carriers such as offset printing plates, lithography films or flexographic printing templates, is an important process step. Because the source data to be used for printing is more and more stored in a computer unit, a computer and then transferred from this computer to the print template or a data carrier, one speaks of the "Computer-to-Plate” (CtP) technology.
- CtP Computer-to-Plate
- CtP devices known from the prior art use principles for transmitting the data, which provide a flat bed or a drum as a holding surface for the data carriers.
- the transfer head for transferring the data and the data carrier that receives the data are always moved relative to one another in such a way that data can be transferred to the largest possible proportion of the data carrier area.
- An external drum system enables the transfer head to be brought up to the plate surface up to a few millimeters. This enables the use of inexpensive laser diodes, which are also easy to focus and can be used as multi-channel exposure heads. To do this, attaching the data carriers to the outside of the drum is constructive and time-consuming to handle (inserting the plates into the centering pins). Damage (kinking) can occur when handling thin offset plates with a thickness of 0.15 mm. In addition, depending on the size of the plates to be exposed, the drum must be balanced differently. If thermal plates are used, dust particles are formed during the exposure, which are thrown directly onto the optics by the centrifugal force and can contaminate them.
- the applicant's combined inner / outer drum system for the present invention combines the advantages of the inner and outer drum systems and eliminates the disadvantages mentioned in each case.
- 0.30 mm offset plates are less sensitive to kinking, but they are relatively stiff in the edge area, so that the plates do not always fit smoothly to the edge, which can have a negative effect on the focus during exposure and also on the suction vacuum.
- the manufacture of these devices is relatively complex and expensive. Because the inner drum for inserting the plates is open at the top, you lose up to a third of the exposure time.
- the object of the present invention is to propose an alternative device or an alternative method which - while maintaining the same quality - is based on an inexpensive construction and enables simple plate handling.
- this object is achieved according to a first aspect by proposing a device with the features of independent claim 1.
- the object is achieved by proposing a computer program product with the features of independent claim 10 or a method with the features of independent claim 15.
- Advantageous embodiments and additional features result from the dependent claims.

- the laser diodes are via individual drivers 15 (32 in FIG. 1) Driver shown) controlled and preferably cooled via Pelier elements (not shown). Maintaining a constant temperature of 24 ° Celsius has proven to be particularly useful because it ensures that the laser diodes are in an optimal state with regard to light output, wavelength cost and lifespan in the usual wavelength range of 830 nm. Deviating from the illustration in FIG. 1, more than 32 laser diodes 14 can also be used - within the scope of the possibilities of the computers used.
- the holding surface 3 is arranged essentially vertically in the device 1, in accordance with a second embodiment of the device according to the invention.
- This second embodiment can facilitate the insertion of particularly large carriers, e.g. aligned on a hanging device hanging on the centering pins and can be sucked onto the holding surface 3 by means of negative pressure before releasing the hanging device.

- the holding surface 3 with the support 4 placed thereon and possibly drawn in by means of a vacuum system rotates about the X axis 8 with e.g. 250 rpm.
- the encoder (E) connected to the motor controller 1 (master) outputs e.g. 5000 pulses / revolution of the holding surface 3 to the motor control 2 (slave) and the PLL.
