be evaporated, such as a solvent or a water compound. It is definitely a matter of design. The system must be developed to minimize energy con- sumption. This is one of the most significant cost factors in the process. Having good control means a competitive advan- tage for the converter. WEB HANDLING With performance and speed rising, the importance of web handling catapults to a critical level. This factor has always been regarded with higher attention in coating processes, as compared to flexo print, primarily because of central impres- sion (CI) press design. The most critical part of the flexo process happens with the substrate, which today is getting thinner. That means, me- chanical characteristics of the press and press accessories become more critical. The ability to properly control the un- winding and rewinding stage is very important and becomes even more critical at high speeds. Technology of motors and drives, once properly selected in function of the relevant tasks, today comes to the rescue. The software package is designed around the targets to be achieved and the web layout influences attainable speed levels. It is paramount to take a mechatronic approach to design. The mechanical, electronic, software, computer and system parts of web handling have to be developed under a coordinated approach and in perfect harmony. It's the only way to fully enjoy the advantages of modern technology. About the Author: Giancarlo Caimmi holds a Ph.D. in mechani- cal engineering from University Federico Secondo, Naples, It- aly.
