Abstract: This invention relates to a web (2) printing unit (5) and a register method to align the different colour planes in a printing press. Despite the use of inexpensive equipment, the invention is able to compensate for diagonal misalignments and lateral shrinking of the web (2). It uses a photocell (40) positioned on each side of the web (2) and can be fully automated. It also performs a fast correction, thereby reducing the waste caused by misalignments.
