Product Description For a long time now, consistent change has been observed in the printing industry. Those who still want to successfully be involved nowadays must above all be able to deliver high-quality products in a fast and flexible manner. Besides, cost optimization is a deciding factor. It is frequently observed that due to machine shutdowns, as well as printing technology typographical or technical problems, the printers get into bottleneck situations. Difficulties with delivery and complaints ensue. From this, enormously high costs soon originate, which needs to be caught as soon as possible, optimized against, or in a best-case scenario, eliminated entirely. About the Author Based on my 20-year-old work experience as a printing instructor and service engineer with the worldwide leading Printing Machine Manufacturers, I will describe efficient methods thoroughly, so that the exact sources of error can be localized, and measures can be taken as quickly as possible.
