A cylinder adapted to contact a web comprising:

• first and second spaced cylinder ends and a cylinder body between said first and second cylinder ends, said cylinder body being adapted to print at least one image, in a first image location, on the web egageable with said cylinder body;
• a cylinder axis of rotation defined by said first and second spaced cylinder ends and said cylinder body, said cylinder axis of rotation extending transversely to the web-travel direction of a web engagable with said cylinder body;
• means supporting said cylinder for rotation in said web-travel direction about said cylinder axis of rotation;
• and
• means shifting said first and second spaced cylinder ends and said cylinder body with respect to each other to impose a cylinder bend on said cylinder in one of a direction in, and opposite to said web-travel direction to displace a location of said at least one image element printed on the web engagable with said cylinder body from said first image location to a second image location, different from said first image location, as a function of said imposition of said cylinder bend on said cylinder.
