I believe Tetra Pak at some point invested heavily in the Drent VSOP presses to replace their aging fleet of Chambon presses which required switching out the complete plate and blanket cylinder 'cassettes' This was very time consuming and required a large area to store the many different heavy repeat length cassettes.
Tetra Pak, a great company. I started working for them in 1984. They were just starting offset and the newly built Canadian plant was only an offset operation. Normally, Tetra Pak runs gravure and flexo presses.
Tetra Pak was a very entrepreneurial company back then and I am sure they still have some of that culture now, although I think it has become a bit more controlled in their management style. Anyhow, back then, Tetra Pak made many big bets on technologies and products and actually there were a lot of failures. But their successes helped propel the company ahead. They let people, who wanted to, to experiment and fail often but also to have the opportunity to succeed at times. I have never found that in any company before or after working for TP.
I have to say that I learned most of my specific new knowledge about the offset process studying and making tests on those Chambon presses. The first crude testing of the ITB concept was done on a Chambon press back in 1991. At the time, an on line density measuring system was also being tested and it was used to help plot the density values and water speed values during the ITB testing. The ITB concept was specifically designed to be able to make a quick test of the theory I had about ink/water balance and the test was successful in that respects. Not good enough for production but demonstrated the science.
At the time, the average set up on the Chambons were about 25 minutes and took a little over 1000 impressions. Co printing products was often done. The presses were roll to roll, so they had to be stopped to get a sample, changes made and then run again. Presses were all fully computerized.
I wish I knew then what I know now because it would have lead to path that would have resulted in a low cost solution to production issues. Instead I took a path developing a multi pump ink fountain system that was expensive and had faults which wasted time and money. But that is history. :-(
Now at Tetra Pak, there are hardly any offset presses in their main production. Some are only used for specialty products. TP has gone back almost fully to their older technologies, which are actually better for their purposes. A whole offset factory was closed a few years ago. Gravure and flexo run faster and have wider webs. Of course, Tetra Pak will always be investigating and then using the latest and best ideas and probably much earlier than other producers.
