High-Performance Diode Lasers for Computer-To-Plate (CtP) Applications
Diode lasers with high reliability and outstanding performance
Computer-to-plate (CtP) is an imaging technology used in modern printing processes. In this technology, an image created in a Desktop Publishing (DTP) application is output directly to a printing plate. This is different to the older technology, computer-to-film (CTF), where the computer file is imaged onto a photographic film. This film is then used to make a printing plate, just like to a contact proof in darkroom photography.
CtP methods differ according to the construction type of the imagesetter and the light source used to expose the plate surface. In terms of construction type there are three different kinds: internal drum, external drum and flat-bed imagesetters.
The two main light sources used to expose the plate are ultraviolet light lamps and laser diodes. The wavelength and energy of the laser diodes depend on the type of plate that is used. This technology is mainly used in newspaper and magazine printing.
TOPTICA's diode lasers provides the required wavelength from 375 nm to 785 nm with a power up to 300 mW. Our iBeam smart laser are already used in many CtP applications and knows for their reliability and the outstanding performance, where quality products are required.
