UV LED Curing System for Litho – Sheet-Fed Offset Press:

UV LED Curing System for Litho – Sheet-Fed Offset Press – Mercury Arc Lamp Was The Standard UV Curing Solution since 1960s
Produce wide range UV and IR light at high energy consumption

Advantages		Disdvantages
Produce vast amount of UV photons Generat full range UV light (1 00-400nm)		High energy consumption High maintaining cost No flexible arrangement Environmental concern of mercury and ozone Long time to warm up and cool down Shutter normally required Limited use to heat-sentitive material

UV LED Is New Solid State Light UV Curing Solution Since 2014
High intensity light at UVA range with many benefits.

Advantages		Disdvantages
Saving up to 70% energy cost Longer life time up to 25,000 hours Saving 90% maintaining cost No IRradiation, suitable for heat-sensitive material Compact and resistant to vibration Instant on/off Uniform radiation across the exposure area No ozone produced, no mercury containing		Limited spectrum range Need more complicated control system Ink or coating fomula need to be adjusted to match LED spectrum

Why UV LED Is Now Qualified to Printing Industry (1)
UV LED single die power output has increased over 4x since 2008.

Also price has reduced around 90-90% from the year 2008.

That makes it possible for wide industrial application.

Why UV LED Is Now Qualified to Printing Industry (2)
New developed packing technology now can reach over 30W/cm² on receiving surface.

Which satisfy most of the industrial applications

Brief Introduction of CoolUV

No.1 Brand of China on UV LED Curing System Market
For 10 years continued research on UV LED curing technology, we’ve built our own knowledge system on how to produce a powerful and stable curing system.

CoolUV now is the most successful brand on UV LED curing system in China .

Products For Different Application
CoolUV has developed various products for printing, coating, adhesive and specific industry customization.

Products Lines for Printing Industry
CoolUV has developed full range of products lines for printing industry.

They can satisfy almost all printing segments demanding.

SuperCure series are most popular and recommended for narrow web printing.

Technology Started the R&D on UV LED Curing Since 2009
For 10 years continue Research on UV LED curing, we’ve built our own knowledge system on the 4 key-technology:
dies packing and optical design, driving design, thermal management.

And friendly integration and application support.

Challenges of Curing Lamps for Sheet-fed Offset Printing
Challenge 1, optical design for the target of the highest radiant intensity on the curing distance of 40-100mm

Challenge 2, lamp length for sheet-fed press normally between 70G-1800mm, power consumption from 6Kw-25Kw.
Such length and high power make great challenge for heat dissipation and temperature uniform on whole lamp.

Excellent Optical Design for Sheet-fed Offset Printing
Two models were developed: UltraCure and UltraCureplus, for common and high power demanding.
-Ultra Cure, applied for cure distance 5-45mm, UV intensity 20-25W/cm2 max.(l 0-12W/cm2@45mm, 8-9W/cm2@1 OOmm)
– UltraCureplus, applied for cure distance 5-l OOmm, UV intensity 30-35W/cm2 max.(12-15W/cm2@1 OOmm).

Excellent optical design offers more advantages than the other brands products.

Excellent Thermal Management – Dies Packing
LEDs produce vast heat during working, dies work at high temperature will cause the great life reduction.

So to run at a working temperature as lower as possible is very important.

Transfer and dissipate the heat quickly and efficiently is a very challenging work, CoolUV start the work from dies packing.

Excellent Thermal Management – Heat Sink Design
Inventive heat sink design can make sure the uniformity of the lamp temperature and also keep lamp working at very low
temperature.

Compact Dimension

Flexible Installation Model
More cables and pipes leading-out combination are available to match different press models.

CoolUV Lamp Has Excellent Life Time
By excellent thermal management, packing technology and driving technology,

CoolUV lamp’s life time extends to over 15,000 hours.

Advanced Controller And Control System
CoolUV developed advanced control technology which is proved very stable and robust.

And also can meet various requirements of most applications.

UltraCure and UltraCure plus Technical Specifications

Inks: A Very Important Factor

Installation Variety
Samples of various installation situation, much more variety is available depending different printing jobs.

Using Cost Comparison Items Between Arc Lamp and Led Lamp

Case Study 1: Using cost for 1 lamps length 1100mm (sample-1)

Case Study 1: Using cost for 6 lamps length 1100mm (sample-2)

Benefits By Using UV LED Curing System
CoolUV LED curing is really a green environmental friendly technology.

By cutting significant carbon emission, zero-mercury
to handling, no changing parts, long using life, the users and our planet benefit very much from this technology.
