Kinegram
Kinegram is a foil-based optical security feature on a banknote that produces controlled, directional movement when the note is tilted.
It is a micro-structured surface engineered to guide light into precise sequences of motion and colour rather than static imagery.
How It Appears
A kinegram appears as a reflective foil stripe or patch, most often positioned vertically or within a defined security field of the banknote.
Its defining characteristic is disciplined movement. When the note is tilted, elements travel along a fixed path rather than shifting randomly. Lines slide, symbols repeat in sequence, and the motion remains stable from one viewing angle to another.
At the same time, colour does not simply change — it progresses. In genuine examples, tones move across a continuous spectrum as the angle shifts, creating a controlled transition rather than isolated flashes. This progression feels fluid and complete, not limited or fragmented.
The surface itself is smooth and sharply defined, forming a clear contrast with surrounding printed areas. At its edges, the foil sits cleanly within the paper, without softness or irregularity, reflecting the precision of the hot-stamping process used to apply it.
Under magnification, the kinegram reveals a dense micro-structured pattern that governs both movement and colour behaviour. These structures do not create depth, but control direction and sequence with high precision.
In imitations, this control breaks down. Movement becomes unstable, colour shifts appear limited or inconsistent, and the edges of the foil may lose their sharp definition.
Functional Role
The kinegram functions as a micro-optical system based on controlled reflection.
It is produced through micro-embossing and hot-stamping processes that imprint a precise surface structure into the foil and integrate it into the banknote. This structure determines how light is reflected at different angles, creating predictable movement and colour transitions.
Because the effect depends on physical geometry rather than printed image, it cannot be reproduced through scanning or conventional printing. Attempts at replication typically result in flat reflection or incoherent visual noise.
The precision of application is equally important. A genuine kinegram sits flush with the paper and maintains a clean, sharply defined boundary. When this integration is absent, the feature loses both optical and structural credibility.
In practical use, the kinegram enables immediate verification. Its behaviour is either controlled and consistent, or it is not.
Why It Matters to Collectors
For collectors, the kinegram is both an authentication tool and a sensitive indicator of condition.
Its value lies in precision. A genuine kinegram responds to movement with clarity, direction, and continuity. This behaviour remains stable across repeated handling when the structure is intact.
At the same time, the feature is vulnerable. Environmental factors such as humidity, heat, or improper storage materials can affect the foil. In degraded examples, the surface may lose its uniformity, developing slight distortions or micro-textural changes that disrupt the optical response.
One of the most telling signs of damage is a loss of surface coherence. Instead of a clean, controlled reflection, the kinegram begins to scatter light irregularly, and the movement loses its defined path. In more advanced cases, the surface may show subtle unevenness, indicating that the micro-structure has been affected.
These changes are not reversible. Once the surface structure is altered, the optical system no longer performs as intended.
For this reason, the kinegram is not judged by brightness or visibility, but by control, clarity, and structural integrity.
Kinegram vs Hologram
A hologram produces depth and layered imagery through light diffraction.
A kinegram produces directional movement and controlled colour transitions through structured reflection.
A simple distinction:
A hologram creates depth within the image.
A kinegram creates motion across it.

Frequently Asked Questions
What is a kinegram on a banknote?
It is a foil-based optical feature that produces controlled movement and colour change when the note is tilted.
How can collectors verify a kinegram?
By observing whether movement and colour transitions follow a consistent, directional pattern.
Can kinegrams be counterfeited?
Basic imitations can reflect light, but they typically fail to reproduce controlled motion and full-spectrum colour behaviour.
Does condition affect a kinegram?
Yes. Environmental exposure and handling can alter the surface structure and reduce optical clarity.
How is a kinegram different from a hologram?
A kinegram produces movement across a surface, while a hologram creates depth within the image.
