•
Violet395nm Lamps is a special light Emitting Diode technique.
•
Violet395nm is used as an complete replacement for traditional mercury based UV lamps.
•
Violet395nm offers an excellent harvest in the field of UV curing.
Violet395nm offers various Advantages over the traditional UV.
•
Violet395nm curing is done by flooding over the Over Print Varnish (OPV) ,inks ,cast and cure
•
to the violet395nm series of lamps
•
This process will result into curing various substrate rather can term any substrate available ,
since it does not generate the heat like conventional UV curing system
•
Many different types of test has been done using different OPV’s
having different properties., like low migration ,high gloss ,odorless , high refractive index

etc…. Many such tests which has limitations in conventional UV curing system
•
Ultimate Solution for any over print varnish , printing ,coating , spray ,roller application etc… as
you can think and apply . Perfect for food grade packaging industry due to ozone free ,
migration free printing and coating

Traditional UV
UV LED
300watts,200watts/inch ,KW depends
upon the size of lamps used , so
higher KW Consumption
It is in milli watts to watts and not KW
(Saves 90% of Electricity)
Requires 3-phase energy
Works in single phase
Takes time to start –loss of energy
Immediate lightning up
Fluctuation in eminence of the
spectrums , broad range spectrum
Narrow range spectrum , of 395nm
constant
Incompatible with Renewable source
of Energy
Can be easily powered by Renewable
source of Energy
High heat ,ozone gas generation ,
mercury based lamps
Zero to room temperature heat , no
ozone , no mercury
High chances of fire , and various
mechanism used to control the heat
resulting more consumption of space
and electricity , risk
Small mechanism , and no fire

Free radicals , which are left
uncured and ultimately results
in uncured , semi cured , odor,
migration
These would not occur in
Violet395nm curing system as
the wavelength is very narrow
and constant remittance i.e.
395nm..

Deflection In Angle for Curing
Conventional UV
Uncured Free Radicals
Angle Of
dispersion
Substrate with OPV
Coated
Reason For Uncured
1) Deflection of light Angle irregular
2) Variation in GSM of Substrate.
3) Variation In GSM of Coating.
4) Fluctuation in Power.

Constant angle for curing
Reason For Fully cured
1) Deflection of light Angle is proper.
2) The reaction is almost
instantaneous and zero emissions
are generated.
3) Complete Penetration Due to proper light
Angle dispersion.

Penetration over Porous Substrate as compared to Mercury
based Conventional UV Lamps:a)
Deflection in angle in conventional UV Lamps is not uniform as in UV
LED is constant. Because conventional UV is reflection technology ,
whereas Violet395nm is direct technology with low power consumption
b)
Penetration is irregular due to broad range spectrum and no constant
eminence , violet395nm emits constant 395nm so best curing
c)
Conventional UV lamps gives ozone and mercury reaction which have a
 Less life and deteriorates after interval of time. resulting in harmful gas
generation
d)
UV LED rays is simply Light Rays gives constant life as life is 85%
higher than Conventional UV lamps.
e)
Emission of Ozone in conventional UV lamp affects the health and
environment of Industry.

There are various applications of Cold UV curing like
Printing- sheet fed , flexo , screen ,pad printing, article
printing ,circular printing
coating - grauver , flexo ,sheetfed , screen spot UV ,
special effects , drip off effect , cast and cure application
special models
Rigid-moulded articles, like scale printing , circular
screen printing ,
Films – met pet printing , metpet coating , through
grauver , flexo , sheet fed offset , screen
Spray coating for , ceramic , wood coating , PCB
,through spray , brush , roller coating flood coating

The sheet-fed press prints on
individual sheets of paper, as
opposed to continuous rolls of
paper used on web presses. Sheetfed presses come in different sizes.
The larger commercial sheet-fed
presses handle much larger sheets
of paper. Sheet-fed presses can also
print on card stock, plastics, metal,
and other substrates.
Some of the parts commonly found
on a sheet-fed press, especially
those used for offset printing
include the printing
plates and plate cylinder, blanket,
and impression cylinder.
Examples: Brochures, business
cards, fliers, pamphlets, books,
and booklets are typically printed
on sheet-fed presses.

Frequently used for printing on plastic,
foil, acetate film, brown paper, and
other materials used in packaging,
flexography or flexographic printing uses
flexible printing plates made of rubber
or plastic. The inked plates with a
slightly raised image are rotated on a
cylinder which transfers the image to
the substrate. Flexography uses fastdrying inks, is a high-speed print
process, can print on many types of
absorbent and non-absorbent materials,
and can print continuous patterns (such
as for gift wrap and wallpaper).
Some typical applications for
flexography are paper and plastic bags,
milk cartons, disposable cups, and
candy bar wrappers. Flexography
printing may also be used for
envelopes, labels, and newspapers.

Free From Odor as the UV coating and inks used does not
contain the BP,ITX etc harmful p/I
Formulated without VOC solvents.
No reaction of OPV with Mercury and ozone Gas which is major
reason for odor if we use even high grade OPV in regular OPV
Lamps.
Ozone gas cannot be removed in conventional UV
Lamps.
High Molecular weight formulation. Hence No Migration.
Food Grade certified OPV can be used in violet 395nm curing.
Photo-initiator used in violet395nm UV OPV is special grade
and by virtue of the chemistry it wont have odor.
Any other photo-initiator cannot be cured with Cold UV process.
Chances of using low grade /quality OPV can be controlled.
