Streszczenie
Casework necessitated the investigation into how pages within a tabloid newspaper could be linked conclusively to each other. An investigation was made into marks left on newspapers by the manufacturing process and the uniqueness and significance of these marks in respect of connecting pages to each other. It was determined that printing presses can leave identifying features on the paper but that this was dependent on the efficiency and maintenance of the machine. Concerning the original problem, it was established that it is possible to connect conclusively a page of newspaper, by means of a physical fit, back to the tabloid it originated from. Each page of such a newspaper will have been separated from another page within the same newspaper during the manufacturing process. Other marks left by the manufacturing process are of benefit to a greater or lesser degree.
