Security Printing

Security Printing

Prevent document fraud & protect sensitive information.

Security is a major concern for documents with a significant trading or negotiable value. Examples of such documents include cheques, registration papers, licences, certificates, event tickets, gift vouchers, ballot papers and voter registration documents.

The integrity of a document relies solely on its acceptance as authentic. Authenticity is threatened by attack from two sources: counterfeiting (the reproduction of a complete document) and falsification (the alteration or endorsement of a document).

The threat of counterfeiting has increased dramatically with developments in print reproduction technology (such as colour photocopiers, optical scanners and digital printers). This has been further compounded by a general complacency in the business world and the courts’ relative leniency towards non-violent white-collar crime.

Lithotech has developed and perfected a comprehensive range of security features, including design effects, security papers and security inks.

Design Effects

Microprint Line

Microprint Line

A line is made up of text that is readable with a magnifying glass, but that would break up into dots when copied or scanned and become unreadable.

Error in Microprint Line

Error in Microprint Line

A deliberate error can be added to the text masking up the microprint line as an additional security measure.

Micro Dot

Micro Dot

A small dot that looks like an ink speckle is deliberately added. If the document is copied, the dot would be left off.

Character Chipping

Character Chipping

The selected typeface is manually altered to trick fraudsters who would retype the text in an obvious font and not recreate the deliberate alterations.

Invisible UV Ink

Invisible UV Ink

The ink is invisible to the naked eye, but shows up under UV. Available in various colours, these inks should be printed on UV dull paper for the best results.

Error in Invisible UV Ink Print

Error in Invisible UV Ink Print

As an additional security measure, a deliberate error can be added to the piece that’s printed in invisible UV ink.

Hidden Message in UV Ink

Hidden Message in UV Ink

A hidden message can be added to the invisible UV ink design as an additional security measure.

Hidden Message in Spot Colour

Hidden Message in Spot Colour

A hidden message can be added to the part of the design that’s printed in spot colour.

Security Pattern

Security Pattern

When colour copied by most high-end high resolution photocopiers, the copier software would recognise the pattern and would either refuse to duplicate or deface the duplication. The copier would display a message that it’s prohibited from copying the original.

Guilloche Pattern

Guilloche Pattern

A unique solid fine line pattern is printed in spot chemical reactive ink. When colour copied, scanned or reproduced, the pattern will break up into dots and will no longer be an unbroken solid line.

Raised Effect Guilloche

Raised Effect Guilloche

A unique solid fine line pattern with raised text is printed in spot chemical reactive ink. When colour copied, scanned or reproduced, the pattern will break up into dots and will no longer be an unbroken solid line.

Criss Cross Guilloche

Criss Cross Guilloche

A unique solid criss-cross line pattern is printed in spot chemical reactive ink. When colour copied, scanned or reproduced, the pattern will break up into dots and will no longer be an unbroken solid line.

Security Papers

Paper is considered to be the first line of defence against document fraud. A document is only as secure as the paper on which it is printed, and the most effective deterrents are proven to be those built into the paper at the time of production.

Our range of security papers includes:

  • Watermarked
  • Security Fibres
  • Chemical Reaction
  • UV Dull

Security Inks

In addition to the security incorporated into the paper, additional (complementary) security can be provided by careful selection of inks that have been tailor-made for specific applications.

Our range of security inks includes:

  • Bleeding
  • Invisible UV Fluorescent
  • Varifuge
  • Heat Reactive Irreversible
  • Water Fugitive
  • Penetrating Numbering
  • Photochromic
  • Thermochromic
  • Solvent Chemical Fugitive
