UV
LED ink (VIP Series)
is for sheet fed offset printing and it is the
symbol of engergy saving and environment friendly ink.
We can
expect excellent performances such as savings, less energy consumption,
shorter warm-up period,
and less Yellowing of the prints due
to lower heating. Besides, UV LED Lamp has longer life time in comparison
with exisiting UV lamp.
1. Wave
Length.
365nm, 375nm, 385nm, 395nm, 405nm
2. Characteristics.
Environmentally
Friendly(UV/LED) sources do not contain toxic heavy metals,no ozone
extraction.
Cost Savings, less energy consumption, shorter warm-up
period, longer LED lamp expectancy.
Less yellowing of the prints
due to lower heating
3. Test
Method.
1) T.V(TacknessV alue) : Value at 400 rpm
by Ink-O-Meter
2) S.M(Viscosity) : Value at 10sec. By Spread-O-Meter
3)
Curing : Finger twisting test by LED Lamp.
4) Room Temperature
: 25 ± 1 ¡É
5) Room Relative Humidity : 60 ±
5%
