SST’s UV LED INK CURING TECHNOLOGY

SST, Inc. has been a pioneer in LED curing solutions for printing since 2005 with the launch of curing systems for adhesives. SST once manufactured its own LED wafers and chips, giving us the technical expertise to customize LED products for each printing market. Since 2005, SST LED innovations for curing inks, coatings and adhesives have been consistently launched and now offer market leading solutions for flexo, screen, offset and inkjet printing. SST UV LED units produce much less heat , significantly more curing dosage, and utilize 75% less energy than conventional LED systems.

Patented AS-LED Technology

SST’s completely unique design have chips directly mounted on copper to ensure the smallest number of insulating layers between the UV LED chips and the cooling water. This minimized temperature difference between LED chips and cooling water allows for room temperature cooling for the LED curing head.

— HEAT GENERATION

Produces almost no heat compared to UV, Water-base or Conventional LED curing systems

— HEAT DISSIPATION

Better dissipates the minimal heat that is generated

— CURING DOSAGE

Delivers the highest ink curing doseage available

— LOWEST ENERGY AND CARBON EMISSIONS

Requires MUCH less energy than Conventional LED, UV, or water-based systems

SST LED Features

Can be customized to utilize 385, 395 or 405 nm wavelengths
SST’s simple and compact system design involves fewer components with no moving parts.
Enables the industry’s only COLDCURE print environment. Cooled only by room temperature water circulation
Provides the industry’s longest dwell window via it’s unique double peak irradiance curve
Includes overheat protection design
Large cooling capacity, no clogging
Water lines can be connected either at front or back
Water channels of the LED curing heads can be linked either in series or in parallel
Scalable from a curing length of 2 inches to 120 inches.

Advantages of SST UV LED over Conventional LED’s

Consumes 75% less energy than Conventional LED and reduces carbon emmissions by the same %s.
Eliminates the need for chilling systems in most print technologies including allowing for flexo printing of high % shrink sleeves without chill drums.
Requires much lower maintenance and press downtime.
Provides the smallest footprint and fastest retrofit available – retrofit in one shift in most cases.
Customizable to fit virtually any print technology or application
Modules can be replaced on-site without returning the unit or reuiring an on-site visit.
Can be retrofit onto almost any press or integrated onto a new OEM press
Eliminates the noise and dirty air movement caused by air-cooled LED systems
Longer effective life as heat is the #1 determinant of LED chip lifespan
Provides cooler working environment for press operators and reduces air-conditioning costs
Eliminates condensation and coolant.

Advantages of SST UV LED over Traditional UV

SST LED provides all the same benefits as compared to Conventional LED and more…

Reduces energy costs and carbon emmissions by 90% + vs UV arc
30,000 hours of expected lamp life vs 800 hours – much more press uptime
Elminates the need for exhaust systems – freeing up space and saving money on equipment, energy and maintenance costs and significantly reducing noise press-side
Eliminates lamp warm up and cool down time with instant on-off lights that are only on when printing.
UV LED curing units do not generate ozone, do not contain mercury, and emit only UV-A wavelength light close to the visible spectrum – reduced health and safety concerns
Lower odor inks than UV
Eliminate mercury bulb disposal and environmental impacts

Advantages of SST LED curing over water-based ink drying systems

SST LED provides all the same benefits as compared to Conventional LED and more…

Reduces energy costs and carbon emmissions by 75% + vs water-based ink drying
Press speeds can be as much as twice as fast to increases current press output or delay purchase of a new press.
Ink mileage per pound will approximateltly double
LED inks provide much stronger color densities and white opacities than water-based
Eliminate the need for an overprint coating in many cases.

Integrated to New Press

The SST LED Curing System can be integrated into the press control through SST’s communication cables.

The power towers have 95% efficiency. The LED curing lamps are fabricated by mounting SST’s patented AS-LED modules directly on the single piece of extruded aluminum heat sink. The patented AS-LED modules are made with rod quartz lenses to minimize TIR (Total Internal Reflection) loss.

The SST LED curing lamps can have independently controlled sections.
