Thanks for the reply. Yes, Ilford has a very modern facility and can turn around rapidly. Some companies don't have that capability and therefore if paper sales decline it is much more economical to cease paper production in the face of the massive cleanup job.
At Kodak Rochester, we never had the problem. There were 6 machines in 3 rooms with 4 operational at any one time. The other two were undergoing refit and cleaning. Of course, these were the most modern. There were also other coating machines. There were two separate buildings devoted to film.
