Zusammenfassung:	A method of preparing cylinders for printing on a web during auto transfer operations is provided. The method includes the steps of printing images on a web with at least one first printing cylinder; accelerating at least one second printing cylinder so that the at least one second printing cylinder has a surface velocity that equals a velocity of the web; adjusting a phasing of the at least one second printing cylinder with respect to the web during the accelerating step and before the surface velocity of the at least one second printing cylinder equals the velocity of the web; moving the at least one first printing cylinder away from the web and moving the at least one second printing cylinder towards the web; and printing images on the web with the at least one second printing cylinder. A printing press configured for auto transfer is also provided.
