SYSTEM OCH FOERFARANDE FOER PROJISERING AV MULTIPELBILDER DIREKT PAO TRYCKPLAOTAR. |
摘要 |
A method and system for direct-to-printing plate multiple imaging. Supported on an overhead beam are a lamp house, a subject holder and adjacent condenser lens system, and an objective lens. The lamp house emits a highly intense, uniformly diverging beam of light which is narrow-banded to avoid excessive heat. The condenser lens system gathers the light and directs it through a film negative or positive on the subject holder. The objective lens focuses the film image on a metal printing plate which is held on a platen and coated with a photosensitive emulsion having an exposure time in the range of seconds rather than minutes. |
