Summary:[Display omitted] Identification of spray paint coats on various surfaces is often a subject of forensic examinations. The layer of paint, which creates inscription and drawing or painting such as graffiti, is thin and difficult to be separated from the base. Model examinations have been carried out aiming at the evaluation of the usefulness of infrared (ATR FTIR) and Raman spectrometry in the identification of paints. Seven red spray paints were placed on the surface of metal and glass slides as well as on paper and on different fabrics. It was found out that a spectrum suitable for identification of the type of paint depends on the thickness of the paint coat and on the type of the substrate.
