Sažetak
The article presents valuables expertise in the infrared spectrum with barrier scanning in order to prove authenticity. Suggestions are given for analyzing forgery information under the soft, intermediate and hard IR radiation. Basic characteristics of pigments are used to create a selected graphic information of color disappearing. Precise scanning was conducted by video spectral comparator with filters for visible and invisible part of the spectrum. Digital databases were created for documenting the results. The importance of IR spectrum separation in thirteen sections is highlighted in order to improve qualitative and quantitative way of information disappearing.
