 Other light sources… whats the difference?

Fluorescent Tubes

Exposure units are an option for the screen printer that manufactures t-shirts, whose art work does not contain very fine lines or half tones. They are usually less expensive and reliable, but a common issue is inconsistent bulb output due to poor connections or worn out bulbs, resulting in underexposed screens. Yearly bulb replacement can be common. It can often be tricky making higher quality high screens with this type of light source, as undercutting of fine lines and halftones is common.

Halogen/Quartz bulbs

are the next step up from the fluorescent tubes. They are single-point light sources, so they do a nice job exposing fine line detail, or half tones, but average bulb life is only around 3,000 hours, and they produce excessive amounts of heat which can be a safety hazard.

Mercury Vapor units

Mercury Vapour lamps are usually around 1000 watts and work very well. Because they are rich in ultra violet light, and can be classified as a single point light source. As long as the light is close to the screen, it will work admirably. Usually, the screens should be placed no further than two feet away from the unit. Any farther away as a result end up with excessively long exposures. Mercury vapor lights have a start-up time and a cool down time, so there is no instant on/off like you get with a fluorescent unit. These are generally moderately priced units.

Metal halide

units are used by screen printing companies that primarily do very high end work or graphic printers that expose very large format screens. They can consume 1000-8000 watts, and exposure units range from roughly £3,000 to £2,000. The bulbs should be replaced every one to two years. It takes about 20-30 seconds for all of the gases in a metal halide lamp to reach full temperature and full spectral output before you can expose properly, so most units stay on, and use mechanical shutters to control exposures.

“Instant on” systems are available that do not require warm up time, but the more times a metal halide lamp is turned on and off the faster it wears out. Some “instant on” type systems will only get 500 hours of use per bulb. These bulbs can be very expensive, and costs can really add up.

 LED Exposure unit has Ultra fast exposures with all types of emulsions.

As a result  Exposure times 10-15 times faster than fluorescent bulbs & 25%- 50% faster than metal halide systems.
 Long lasting, consistent bulb output. LED lights don’t fade or weaken over time like traditional bulbs. Bulb life expectancy is 50,000-100,000 hours.
Lower power consumption. Less expensive to operate on a daily basis than most other exposure units. Operates at 20% of the power required by metal halide units.
Safety.  No excessive heat or high voltage power supplies and shutters needed. This eliminates the need for multiple cooling blowers, keeping you cooler while saving you money!
No Maintenance. 
 LED UV lamps can last more than 50 years. Imagine what you can do with all the savings!

Efficiency through quality light.

Finally the  portion of the light that matters to exposing a screen is the light. Which affects the sensitizer and initiates the cross linking (the bright bluish ultraviolet light- not the white and yellow light). With LED UV exposure technology, there is no wasted white light.
