The fiber-optic coupled laser diodes operate in the 405 nm range and boast an ultra-long service life of +20’000 exposing hours. They are completely maintenance-free and do not require any active cooling system.
The laser diodes have a high-power capacity, so their energy can be adapted to the requirements of every emulsion. There is no need for high speed CtS emulsions: Any standard emulsion can be exposed and cured by JetScreen ! LT round.
Prior to every exposure, the system checks the default laser diodes settings relating to the emulsion to be exposed and automatically checks and calibrates the laser diode if necessary. This guarantees consistent quality and eliminates exposure errors.
JetScreen! LT round does not require any consumables such as MH lamps / UV lamps / LED’s or DMD chip. Lüscher maintenance software guides the operator through the simple maintenance tasks and guarantees high reliability. JetScreen! LT round is equipped with a port for Remote Support Service, which can be directly linked to our technical support via internet.
Lüscher’s unique laser diode technology guarantees extremely low power consumption of 0.5 kW and lowest cost of ownership. This helps the customer to achieve environmental-friendly production.
The direct exposure system is modular and may be tailored to the requirements and special requests of the customer. The standard configuration includes one 1’200 dpi setting head with 16 individually controllable laser diodes.
Depending on the laser diode configuration, JetScreen! LT round exposes a screen coated with a standard emulsion, a repeat of 640 mm and a length of 2’200 mm in less than 5 minutes.
