Zusammenfassung:	A system and process for aligning printed images on a rolled product with perforation lines being formed into the product is disclosed. According to the process, the position of printed images are sensed as the images are being printed onto a substrate, such as a tissue strip. The images are printed onto the substrate using a printing device including at least one rotating print roller. In order to maintain the printed images in alignment with perforation lines being formed into the substrate, the speed of the print roller is adjusted in order to adjust the length of the printed images.
