I believe that PIA/GATF have a ratios study that they publish yearly that gives some of this info. As well GATF have good information and technical help. I suggest you check their website. A good book is called 'War on Waste'. As I have been off the shop floor for some years there may be betterones out now but this is where it all starts.

In general printers tend to have internal systems to measure yields etc. Make sure yours can be cross checked, as internal systems tend to not get validated.

To give an example: if the (roll wrapper + web + bindery + mailing) waste is totaled, it must equal the amount of paper that is recycled plus the little bit that ends up in the trash. (Yes I know; P2 plants don't put any paper in the trash).

A problem on low quantity runs is that the press never gets 'to speed'. Ink and fountain solution are formulated to run at a speed that is based on the press max speed, and not getting above make ready speed can yield all sorts of press problems. Get you suppliers involved.
