The easier it is for a document examiner to confirm the authenticity of a passport, the more secure it is deemed to be. The passport is a document that faces many threats, but most can be identified if security and tamper evidence are paramount in its specification.
Over recent years, at Portals, we have seen a growing trend to move towards a 100% wood pulp furnish or a blend with wood pulp as the predominant constituent for passport substrates. This brings several advantages, including an opportunity to enhance the security of the passport and improve its overall tamper evidence.
Watermark clarity
A mould-made watermark is recognised as the most secure, but its presence alone is not the solution. It must have high clarity and be easily recognised. This is best achieved with the shorter fibres of wood pulp.
Fragility is strength
If the personal or issuance details of a passport have been altered, this should be easy to identify from the disturbance of paper fibres at the site of the alteration. The shorter fibres of wood pulp are less tightly bonded within the paper and more easily disturbed.
Furnish blend
With the inclusion of wood pulp to the furnish, paper manufacturers are able to delicately control and balance this blend to ensure both durability and exceptional watermark clarity are met.
Chemical sensitisation
If a chemical substance is used to attempt to alter the information printed on the sheet, the specific area of attack will react to that chemical and show up as a coloured staining, the colour of which indicating the type of chemical being used.
Permanent reaction
Any alteration or attempt at removal of data via chemical abrason results in an immmediate and obvious colour reaction that is permanent.
Protection against a range of chemicals
Portals can add a range of sensitisation agents depending on the needs and threats to the document. These include sensitisation agents that react to Ethanol, Cellosolve, Methanol, Acetone, Bleach, Pet Ether, Isopropanol, Sulphuric Acid and Sodium Hydroxide.
