In the examination of questioned documents, problems involving the source or authenticity of carbon copies may be encountered. The copy presented may have been prepared through the utilization of individual sheets of carbon paper, or it may have been produced through a carbonless paper system. In some cases it may be significant to determine whether the copy was produced in the conventional manner or with a carbonless system and, if the latter, which particular carbonless system was utilized. For these reasons, a study of the carbonless systems currently in use was undertaken.
