Tri-Light CTS™ is the dual-purpose version of NuArc’s popular Tri-Light ST™ Screen Exposure System. It produces the same exceptional results on conventional screens, but it also exposes screens that have been generated by CTS computer-to-screen imaging systems, making it the logical choice for those using both screen types—and for conventional screen printers planning for the future. Tri-Light CTS is also simple to operate. The entire screen exposure process—from vacuum drawdown (on conventional screens) through screen exposure and vacuum release—is accomplished with a single keystroke.

Tri-Light CTS has two methods of exposing screens. Two outer latches provide access to a conventional glass-and-vacuum blanket capable of handling screen frames up to 132 x 152 cm (52” x 60”). A center latch bypasses the glass and vacuum in favor of an adjustable computer-to-screen rack system for exposing computer-generated screens directly to the light. The rack will handle a maximum screen frame size of 142 x 163 cm (56” x 64”), and will accommodate two 64 x 91 cm (25” x 36”) or four 58 x 79 cm (23” x 31”) screen frames simultaneously. The separation provided by the rack system eliminates the smearing and distortion that can result from screen-to-glass contact. On conventional screens, NuArc’s unique manifold system ensures intimate contact by drawing vacuum evenly around the perimeter of the blanket frame.

NuArc’s computerized and programmable integrator/controller ensures precise vacuum duration and screen exposure lamp output compensation. Screen exposures are powered by NuArc’s instant-start 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 screen exposures when necessary. They also extend Tri-Light CTS’s ability to adapt to future emulsion formulas. Tri-Light CTS also features NuArc’s exclusive Proportional Temperature Control (PTC). PTC continuously monitors screen exposure lamp temperature, turning cooling fans on and off to keep the exposure lamp at the optimum operating temperature. Tri-Light CTS can be located in areas housing unexposed screens because the light source and vacuum frame are enclosed, and the screen exposure lamp can’t be turned on while the blanket frame is open.
