A method for incorporating graphics (21, 21a, 21b) into absorbent articles (10). The method involving: providing a moving substrate (17) to a print cylinder (85); sensing a line speed reference signal from a line speed target machinery component; rotating the print cylinder (85) at a predetermined speed, based on the line speed reference signal, printing a series of graphics at a predetermined distance frequency; sensing a phase difference signal from a phase target machinery component; and setting an actual print cylinder phase angle, based on the phase difference signal, to thereby position a series of graphics.

L'invention concerne un procédé et un appareil permettant d'incorporer des éléments graphiques (21, 21a, 21b) dans des articles absorbants (10). Ce procédé consiste à : acheminer un substrat mobile (17) jusqu'à un cylindre d'impression (85), détecter un signal de référence de cadence en provenance d'un composant de machine cible du point de vue de la cadence, mettre en rotation le cylindre d'impression (85) à une vitesse prédéterminée d'après ce signal de référence de cadence, imprimer une série d'éléments graphiques à une fréquence de distance prédéterminée, détecter un signal de différence de phase en provenance d'un composant de machine cible du point de vue de la phase et définir un angle de phase réel du cylindre d'impression d'après ce signal de différence de phase en vue de positionner une série d'éléments graphiques.
