| 摘要 |
The invention relates to a personalisable support comprising anti-forgery devices which are provided in order to indicate every attempt of fraudulent personalisation. The support comprises a body (2) which is on one side equipped with personalisation data (6,7) which are obtained by carbonisation of the base material by means of a laser beam. The anti-forgery devices (8), which totally or partly cover these personalisation data, draw a pattern (90, 80) along which bubbles (9) are created whose density (d1-d5) varies depending on the degree of carbonisation of the areas (61-65) which are covered by the pattern.
