6.4 SCANNER AND OPTICS
6.4.1 SCANNER OVERVIEW
6
1. Exposure Lamp
2. 1st Scanner
3. Exposure Glass
The original is illuminated by the exposure lamp (a xenon lamp). The image is
reflected onto a CCD (charge coupled device) on the lens block via the 1st, 2nd,
and 3rd mirrors, and through the lens on the lens block.
The 1st scanner consists of the exposure lamp, a reflector, and the 1st mirror.
A lamp stabilizer energizes the exposure lamp. The light reflected by the reflector is
of almost equal intensity, to reduce shadows on pasted originals.
There is no original size detection. All masters are printed at full size.
