METHOD FOR PRODUCING PRINTED PRODUCTS

摘要

A method for producing printed products in a production plant, equipped with a digital printing press and at least one post-print processing machine arranged downstream of the digital printing press. The printed products are produced according to work orders for which the digital printing press prints on a print material web. The post-print processing machine processes the print material web into printed products. The production plant is converted for producing different printed products to be produced in a following work order, relative to a preceding work order. A time interval is initially determined for adjusting the post-print processing machine with the longest adjustment time. The post-print processing machine to be adjusted begins with the adjustment as soon as the last printed product of the preceding work order leaves this post-print processing machine. The post-print processing machine to be adjusted then starts processing the following work order as soon as the predetermined time interval for adjusting the post-print processing machine has elapsed.

1. 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 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 the conversion involves an adjustment operation in which an adjustment is made during a conversion interval to at least one of the post-print processing machines 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; and starting processing the following work order by the at least one post-print processing machine to be adjusted as soon as the determined time interval for adjusting the post-print processing machine with the longest adjustment time has elapsed, following a start of the adjustment operation.
