Tri-Light ST

Product Details

Tri-Light ST is a larger, shuttered-light version of NuArc’s popular Tri-Light Exposure System. With its 132 x 152 cm (52” x 60”) maximum screen frame size; fast, powerful light source, and exceptional repeatability, Tri-Light ST is perfect for high-volume operations. NuArc’s computerized and programmable integrator/controller ensures precise vacuum duration and lamp output compensation. Tri-Light ST is also simple to operate. The entire exposure process—from vacuum drawdown through screen exposure and vacuum release—is accomplished with a single keystroke.

NuArc’s unique manifold system ensures intimate contact by drawing vacuum evenly around the perimeter of the blanket frame. Exposures are powered by NuArc’s multi-spectrum metal-halide System 631™, which idles at 1 kW and operates at user-selected settings of 6 kW, 3 kW and 1 kW. The 3 kW and 1 kW settings allow operators to slow down exposures when necessary. They also extend Tri-Light’s ability to adapt to future emulsion formulas. Tri-Light ST also features NuArc’s exclusive Proportional Temperature Control (PTC). PTC continuously monitors lamp temperature, turning the cooling fans on and off to keep the lamp at the optimum operating temperature. Tri-Light ST can be located in areas housing unexposed screens because the light source and vacuum frame are enclosed, and the exposure lamp can’t be turned on while the blanket frame is open.
