Security Features

Security features are the techniques used in documents, labels, seals, or tamper-evident devices to make counterfeiting more difficult and combat fraud involving products, documents, tickets, and other materials. Companies that need Primi's security printing solutions are seeking to protect their assets, ensure authenticity for consumers, and prevent major losses caused by fraud.

A key step is defining the appropriate security level. Depending on each necessity, Primi Tecnologia works with three levels to classify the security-printed features and create an exclusive DNA for the product.

Security Levels and Features Used byPrimi

Level 1: Consumer

These are features that are easy to identify and do not require special equipment or technical knowledge. They are usually detected by touch or sight and are widely used around the world. They include:

Machine-iris numismatic security background: exclusive and customized backgrounds. Foreground images combine microimages or lines that deform individually, creating depth, light, and shadow;
Anti-scanner background: a system that prevents the document background from being copied through scanners or photocopies during attempted fraud;
Line-based numismatic backgrounds: textured backgrounds with customized colors, lines, and tones;
High-frequency modulated background: images formed in the paper background through line structures;
Offset printing with machine-iris effect: gradient effects in printed materials with continuous, smooth color transitions, created without dots through the use of specific inks in the offset process;
Intaglio printing: a tactile groove or relief applied to the material, making copying more difficult;
Watermarked security paper: exclusive protection and durability through a dedicated watermark;
High-security holography: exclusive holographic foil with chromatic changes depending on light incidence. More complex than conventional holography, it combines colors and bright lines in a single holographic design;
Overprinting on holography: microtext printed in specific positions over a holographic element, creating unique layered images;
Permanent indelible sequential numbering: numbered marking using microperforation, visible or discreet depending on the application;
Microperforated numbering: a feature that makes copying or tampering more difficult and may also be sequential;
Optically variable ink: ink that changes depending on light incidence or exposure to black light or ultraviolet light;
Tactile raised printing: numbering or graphic design elements printed in relief;
Transparent window: a clear or open section in the printed material, similar to security windows used in polymer banknotes;
Guilloche: geometric line patterns that give security-printed backgrounds a unique identity;

Level 2: Inspection Authority

This level includes Level 1 features along with more specific and detailed techniques, which may require basic training, inspection tools, or access to confidential information. These include:

Hidden line image: an image concealed within the background lines, visible only with a transparent inspection film or dedicated viewing device;
Hidden microtext image: similar to the above, with the hidden image formed by microtext;
Variable hidden image: a hidden image that may appear in different areas of the document and, depending on the application, may vary from batch to batch. It is visible only through a dedicated app or inspection film;
Invisible anti-copy background: elements visible only under black light or ultraviolet light. They do not appear in photocopies or scanned images commonly used by counterfeiters. This is a complex security background produced with colorless ink invisible to the naked eye;

Level 3: Forensic Analysis

This is the most technical level and may combine features from Levels 1 and 2. It involves technical security solutions that identify the origin and production process of the document. Identification requires specific training, forensic courses, examinations, laboratory analysis, and advanced technical knowledge. Examples include:

High-security numismatic backgrounds: textured backgrounds with colors, lines, and tones, produced with more advanced and complex technology;
Encrypted hidden image: encryption applied to images, allowing secure customization of security-printed materials;
Indelible numbering: permanent numerical sequences printed with technology that prevents removal, even through chemical substances, reagents, or mechanical force;
High-security holography: advanced holographic features, often not identifiable to the naked eye;
Technical flaws: intentionally introduced printing, format, or component variations that make the document unique and help identify its issuer;
