The Topic

The following presentation is to illustrate thebenefits of adding secure elements to plasticdocuments without additional production steps.

The application of these security features canbe found in ID cards, drivers licenses, socialinsurance cards, bank cards, credit cards, access control cards, tickets and passportdatapages.

General options for enhancement of efficient and

precise card production:

- Cassette System

- Positioning System

- Surface Coating

- Datapage lamination plate solution

Cassette Systems

Cassette system enhances productivity of card manufacturing.

High-precision register pins in the bottom cassette and semi-circular notches in the lamination plates create perfect engagement between lamination plates.

Plates patterned on both sides can be used. Positioning system guarantees the sheets are perfectly placed.

Corrosion-free surfaces and low weight.

Lower cycle time = efficient production & excellent card quality

Positioning Systems

Position systems ensure the precise transfer of securityand design features to the laminate.

- Positioning systems with pins outside the lamination- Positioning systems with pins and punched collated

set of sheets

The collated set of sheets is positioned with pre-punchedholes on the pins on each lamination plate. This allowslarge press sizes to be used in the best possibly way withsmall printing formats too.

Register pins are applied to the base plate and insertedinto precision holes in the lamination plate. Whenstacked, the plates cannot move against one another.

Scratch-resistant Coating

Scratch-resistant coating is not a security feature but rather a technical improvement that reduces the costs of secure elements per card significantly. When applying a scratch-resistant coating to a lamination plate the durability of this plate is enhanced significantly. Making the plate so durable it will last several years of cause reduces the replacement rate and reduces the total costs of the project.

The thickness of this coating is 25µm and up to 50 µm per side applied on a through hardened carrier material. The coating is scratch resistant and the supportive carrier material underneath creates a solid base that prevents indentions and cracks in the coating.

Long plate lifetime = Low replacement costs

Surface Treatment for lamination plates

Non-stick coating

-Significant reduction of surface adhesion without process parameters and the structure of the surface.

-Reduces electrostatic built-up significantly.

-Coating thickness is only a few nanometers.

-Suitable for all card materials.

-Can be applied at customers facilities.

Surface Treatment for lamination plates

Release Coating

-Creates a non-stick effect to the lamination plates while not impacting other surface properties such as gloss level, surface textures etc.

-It is a permanent thin plasma polymerisation process based layer. It infiltrates the surface and minimizes surface adhesion of plastic materials on lamination plate surfaces.

-Prolonged lifetime of lamination plates with higher production efficiency due to less material remainders on the lamination plate.

-Suitable for all card materials.

Different customized card surface

-Intented and raised structures

-Matte surface pattern

-Glossy surface pattern

-Matt and glossy surface pattern

-Partial surface pattern

Benefits of secure elements withoutadditional production steps

- high level of fraud resistance against copies and alteration of dataon original documents- easy application on various plastics- no additional process steps to add security features- integral part of the design - easy document verification on different inspection levels with andwithout tools

Datapage solution

One of the key issues of producing a plastic datapage for passports is the solution for the hinge so the sewing area of that datapage: flexible, but durable with no additional process.

Lamination plates with raised dams form a thin and flat hinge area to allow easy lamination of plastic sheets with hinges made of fabric, polyurethane or others.

Anti adhesive coatings allow a flexible selection of materials for the hinge.

Raised and inlaying texturesVery fine surface textures indented into or raised on the card surface with a line width as little as 0,025mm that form guilloches, images, coat of arms, etc.

A special case: MicrotextTo form a very high security surface, a microtext is applied that is only a few microns in font size. Parts of not all of the text cannot be read due to the extraordinary small size of the letters.

Can be applied on all materials as visible or tactile element.

Typically the size of the elements is varied to account for different inspection levels.

Latent ImagesSimilar to guilloche patterns multiple parallel lines are arranged. Within these lines an image is created by altering the angle or width of these lines. The alteration then creates an effect of shadow or reflection which makes the latent image visible. Under straight view the latent image cannot be seen.

A latent image can be applied on all materials.

Most commonly a latent image is used as part of the design for inlaying textures.

Matte or Ghost Image

A very fine matte area is applied on the glossy card surface (or vice versa). This matte area is not visible without light reflection on the card. As the matte reflects less light then gloss the images appears under reflection.

A matte image can be applied on all materials.

Most commonly a matte image is used as part of the design for inlaying textures.

Multiple Laser Image (MLI) and Changeable Laser Image (CLI)

An array of lenticular lenses are applied to a card body. Each lense is only a few micron in size with the smallest being 30µm in radius only. The lenses are then laser personalized from different angles. When looking at the card the image then changes depending on the viewing angle.

The MLI/ CLI requires Polycarbonate.

To enhance the document security the MLI/ CLI can be applied inlaying inside the card body.

Multiple Laser Image (MLI) and Changeable Laser Image (CLI)

The MLI and CLI require a special card construction that matches the lense specifications in order to give a good resolution and proper flipping effect.

Laser personalization of these cards requires a machine that can work from different angles.

Printed LenticularSimilar to multiple laser image or changeable laser image an array of lenticular lenses as are applied to a card body. However these lenses are not laser personalized but are combined with multiple images which are applied in printing. When looking at the card, the image then changes depending on the viewing angle.

It does not require Polycarbonate.

To enhance the document security printed lenticulare can be combined with a changeable laser image and/or multiple laser image meaning that parts of the image are printed and others are personalized.

Multiple lens Technology

Hexagon shaped lenses are applied to a card body. In combination with a fine printing pattern a floating effect with 3dimensional depth is perceived. This feature combines a high definition surface with printing capability to form an extraordinary security level.

Multiple lens technology can be applied to any plastic material.

The depth effect combined with movement allows an optical validation without tools in approx. 1 sec making it an optimum choice for border crossing documents

Holographic EffectAn exceptionally systematic alteration of the card surface causes an reflective effect similar to a hologram however without additional substrates and process steps. When viewing the card from different angles a flipping effect between different segments is viewed.

Hologram Effect Nano Technology can be applied on any material.

For an enhanced durability the image is typically embedded in textured segment of the card.

Braille lettering

Braille lettering is produced in the same lamination step(hotstamping not necessary).

Typical Braille dot height 140 – 160 μm (according to ISO standard).
