With a single point light source, there are fewer angles of light that hit the film and emulsion. Less angles result in diminished light wrap around fine details.* The Y-Series maintain image integrity and resolution. A single point light source can hold the fine detail work needed for Sim Process and CMYK printing.

*Multipoint light sources like UV tubes will have more light scatter, making the finer details more difficult to properly resolve. UV light sources are the worst while LED tubes are far better.

Not only does the single point light source emit the most concentrated light, its bulb type enhances stencils as well. The Y3942 uses a custom, high output LED bulb (405 nm) manufactured for exposure units. The LED bulb outputs an optimal UV wavelength, which can be used on all types of emulsions. Printers can rest assured that the LED bulbs will last more than 10,000 hours, which is better for the printer and the environment.

Plus, the Y3942 has a reflective display, which triples the power of its nearly 450 watt light source. You can expose a 25”x36” screen with photopolymer emulsion in under 10 seconds.

The optically clear, tempered glass in the Y-Series allows more than 99% of the UV light through without disruption to the wavelength. All units feature two, light-safe T8 LED Amber inspection bulbs, doubling the use of the exposure unit as a screen inspection table. The Y-Series are designed to perform.

The vacuum lid creates the tightest positive contact between the glass, film, and emulsion. Having tight, strong contact to the point where the black ink on the film is almost embedded into the emulsion means that light has difficulty wrapping around the film. The end result — a straight, clean burn with sharp edges. Vacuum units provide a superior tool for creating detailed image resolution.

Everything starts and ends in the darkroom. Build a solid foundation from the screen up with the Y3942 today.
