Methods and apparatus for printing and collating multiple webs of materials, particularly for use in creating personalized direct mail materials, are disclosed. The invention includes a single, highly flexible press having components capable of being driven at unequal speeds to account for different sizes of insert materials and their associated envelopes. Operating a single press in this manner reduces the amount of waste web material which otherwise would be present. The press similarly includes novel collating and inserting apparatus whereby each outgoing envelope is effectively formed around the "insertable" materials. Control mechanisms and verification systems associated with the press additionally maintain any personalized materials in registration, permitting a single press to produce the entire direct mail piece from multiple webs with minimal waste.
