“…[4] Even the most of documents is viewed electronically on smart devices including computer, mobile phone, e-book reader; documents frequently is encountered on the form of newspaper, passports, agreement, threatening letter, historical document, envelopes, and books. [5,6] Traditional document papers are mainly consisting of cellulose, hemicellulose, and lignin, which derived from wood. Moreover, some fillers such as calcium carbonate (CaCO 3 ), kaolinite, dyes and polymer materials are added in order to improve the final product according to usage area.…”

Forensic document examination has been considered one of the most important fields in the forensic science. For this, a quick, effective, and cheap techniques for evaluation of forensic evidence is highly required. This study explores the comparison of A4 document paper by chemical and physical analysis. 16 of white A4 paper from different brands were analyzed by FTIR for investigation of structural characteristics. Video Spectral Comparator 8000 has been used to compare the A4 papers under different light source. The inorganic filler composition in the paper is also explored by ICP‐OES. The calcium carbonate content in document papers play a discriminant role which found to be between 16.02 % and 35.54 %. Also, water contact angle has been utilized in order to examine the surface of paper which is generally related to the inorganic filler and other additives. The WCA results ranged between 83° and 111° that enable quick and easy way to compare A4 document papers. The experimental results have demonstrated that besides FTIR methods, other methods such as ICP‐OES for elemental composition, WCA for wetting test, VSC for visualization under different light of source could have been applied for comparison of document papers in case of criminal cases.
