Method for producing printed products

A method for producing printed products in a production plant, equipped with a digital printing press and at least one additional post-print processing machine arranged downstream of the digital printing press, wherein the printed products are produced according to work orders for which the digital printing press prints images and process-technical elements in a conveying direction onto a print material web transported with a first web speed, and wherein the at least one post-print processing machine then further processes the print material web to form the printed products, wherein the production plant is converted if a following work order requires a production of different printed products than for a preceding work order, wherein a conversion involves an adjustment operation in which an adjustment is made during a conversion interval to the at least one post-print processing machine and wherein the print material web continues to be transported through the digital printing press during the conversion interval, the method comprising:

• initially, determining a time interval for adjusting a post-print processing machine having a longest adjustment time;
• beginning adjustment of the at least one post-print processing machine to be adjusted as soon as the last printed product of the preceding work order leaves the post-print processing machine to be adjusted;
• starting processing the following work order by the at least one post-print processing machine to be adjusted as soon as the time interval for adjusting the post-print processing machine with the longest adjustment time has elapsed, following a start of the adjustment operation;
• and
• transporting and printing on the print material web while the first web speed remains unchanged during the conversion of the production plant.

• and
• the print material web is transported and imprinted during the conversion of the production plant with a second web speed that is reduced relative to the first web speed.

• and
• wherein at least one post-print processing machine of the production plant is a folding device, and the method further comprises:
• converting the production plant by adjusting the folding device;
• folding the print material web for successive work orders according to an unchanged folding pattern;
• and
• producing the printed products with a different format by cutting the print material web transverse to the conveying direction and folding the cut print material web according to the unchanged folding pattern.
