Abstract (en)
The document, such as a check and the like, with forgery prevention means, comprises a sheet-like element (1) having at least one portion for writing indications (2,3,4). The peculiarity of the document is constituted by the fact that it comprises, in the at least one portion for writing indications, regions (10) printed with an ink which can be erased by chemical and/or mechanical action. These regions give a preset color response when they are illuminated by a light source of preset wavelength in order to visually point out that tampering of parts of these regions has occurred. <IMAGE>
