Method for Supplying a Web of Material of Predetermined Length to a Printing Press For Producing a Printed Product

A method of supplying a web of material of predetermined length to a printing press for producing a printed product during a current production run, including:

• determining a length of a print run of the printed material to be printed continuously;
• determining a length of the web of material based on said print run;
• forming the web of material length using a plurality of partial webs joined in a line in succession, at least some of said plurality of partial webs having partial web lengths different from each other;
• providing a storage facility and using such storage facility for storing said plurality of partial webs of different partial web lengths;
• providing a material supply system having a material supply system control unit for controlling said storage facility;
• providing a production planning system having production data;
• using said material supply system control unit for determining a demand for selected ones of said plurality of partial webs based on said production data;
• feeding said selected ones of said plurality of said partial webs of material to said printing press in a defined sequence using said material supply system control unit;
• providing said defined sequence with at least one of said selected ones of said plurality of partial webs having a minimum length;
• determining a web of material transport speed;
• determining a cycle period of said printing press as a period of time during which one of a web of material and a partial web of material is being prepared for introduction into said printing press;
• and
• determining said minimum length of said last one of said plurality of partial webs based on said web of material transport speed wherein an end of said production run is reached using said last one of said plurality of partial webs at the earliest when said cycle period has elapsed.
