Tri-Light ST™ is a larger, shuttered-light version of NuArc’s popular Tri-Light™ Screen Exposure System. With its 132 x 152 cm (52” x 60”) maximum screen frame size; fast, powerful multi-spectrum metal-halide UV screen exposure 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 screen exposure lamp output compensation. Tri-Light ST is also simple to operate. The entire screen 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. Screen exposures are powered by NuArc’s multi-spectrum metal-halide System 631™ screen exposure lamp, 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 screen 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 screen exposure 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 screen exposure lamp can’t be turned on while the blanket frame is open.
