Introducing innovative UV technology…violet395nm…….

High power UV LED – the benchmark for UV needs

www.violet395nm.com

Brief about UV LED• 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

UV LED a synonymous for Energy Saving Illumination

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

UV processingFree 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..

Conventional UV Curing

Uncured Free Radicals

Reason For Uncured1) Deflection of light Angle

irregular2) Variation in GSM of Substrate.3) Variation In GSM of Coating.4) Fluctuation in Power.

No Uncured Free Radicals

Reason For Fully cured1) Deflection of light Angle is proper.2) The reaction is almost

instantaneous and zero emissions are generated.

3) Complete Penetration Due to proper lightAngle dispersion.

Advantages ofConstant wavelength

1)Constant Wavelength Cure 100% of OPV.

2)No chance of Miss hit.

3)No- Odor.

Advantages of UV LED on Porous Substrate

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.

Advantage of our LED Intensity of violet395nm LED is high

compared to any other LED UV productsThe violet395nm no dark areas

Providing life <10,000hrs. Constant spectrum of 395nm improves curing Low maintenance cost after a prolonged

period of time. Mercury and ozone free Instant illuminating time

Application

There are various applications of Cold UV curing likePrinting- 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

Sheetfed Printing machine The sheet-fed press prints on

individual sheets of paper, as opposed to continuous rolls of paper used on web presses. Sheet-fed 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.

Flexography 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 fast-drying 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.

OPV for UV led• 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.
