Two Kind Of Scratch-Off Cards: -
PVC
- Paperboard |
| |
 focuses particularly on two types
of scratch-off devices:• Scratch-off label
This is a transparent label on which a layer of
scratch-off material is deposited; the scratch-off
application comprises a base in the chosen color with
subsequent personalization with multicolor logos, text,
and images (also with "invisible" UV ink). One variant
consists in applying a coat of thermo chromatic lacquer
that reacts to temperature variations by changing color.
• Scratch-off panel
Applied by a heat process directly onto the card by
depositing one or more coats of pigment to ensure
virtually total invulnerability of data. A significant
variant is a prismatic panel characterized by the
orientation of the surface layer, which refracts
incident light to create appealing moving-image effects.
This technique is compatible with all colors, while
personalization with text and graphics makes it possible
to create innovative layouts that include the panel. |

Tips • Thanks to their
distinctive characteristics, scratch-off systems
constitute an important, highly secure anti-counterfeit
system. The cards can also become appealing and highly
original gadgets.

Applications •
Prepaid cards for fixed line telephony and specific
mobile telephony call credit cards
• Gadget cards for lotteries (e.g. scratch and win)
• Promotional cards for contests

SECURITY FEATURES
When utilized as a security device, scratch-off labels
are just one of the several security features offered by
UniCard. Other systems in use to ensure valid protection
against forgery and counterfeiting include:

|

HOLOGRAMS Holograms
are security devices that can be personalized with text,
images, and company logos; they are also efficient,
high-impact communication features. A holographic image
is generated using laser technology that exploits the
refraction and reflection of light to create one of the
most sophisticated devices in the «security sector*, as
witnessed by their widespread use on credit cards.
Holographic images can be created with two or three
dimensions and with multiple animations in all
directions.
|
| |
|
INVISIBLE UV INK
Offset or screen printing with special UV ink: UV ink
does not affect the aesthetics of the graphic design
because it is visible only under a Wood light and not
with the naked eye.
This highly effective authenticity verification
method can be employed to create images and textures
that are highly resistant to forgery attempts.
|
| |
|
BACKGROUND TEXTURES
Special coatings in relief applied with offset
technology.
The contrast created between glossy and matt areas is
visible only when viewed against the light. It is also
possible to reproduce text, images and logos that are
perceptible only to the touch.
