Pre-Press Department
The pre-press department is divided into two main parts: On the one hand the area where incoming data from several publishing houses is received, sorted and stored and on the other hand the area for the exposure of aluminium plates for the priniting process. Our pre-press department is able to handle two types of incoming data, already ripped TIFF-G4 data or PDF files which have to be placed on special templates and ripped afterwards.
For the administration of all incoming data we use the central controlling system AGFA:ARCITEX, which distributes the ripped pages to six AGFA:POLARIS-imagesetters. These machines are equipped with special violet laser diodes (405 nm wavelength, 60 mW power) and guarantee a very stable exposure process, high quality and a low consumption of energy. Up to 850 plates can be manufactured in one hour.
The photosensitive layer of the printing plate is hardened with the help of a laser beam and is printed later. The non-printing spots are washed out with special solutions, afterwards the printing plate is covered with a special gum. After that the plates go through a video based stamping and bending unit, then they are transported via conveyor belt to a sorting system with 66 pockets and are stored there until the press operators collect them.
