Here are the recommendations re. reducing makeready wastes that are
presented in the "Green and Profitable Printing" video training
series (Module 3 of 4):

* Keep dampening system clean
- clean and condition dampening system frequently
- clean cloth-covered dampeners once per shift
* Maintain accurate plate-to-press registration
* Do your press set-up by the numbers
* Document the press used and all press settings on the job jacket
* Check impression pressure
* Adjust ink & water fountain settings
- to initial settings if job is a re-run
- to standard settings if job is a first run
* Choose compatible ink and paper

My experience is that the most important place to begin for most
printers is to start to track amounts of makeready wastes and, to the
extent possible, to break down according to press, shift, and cause
(e.g., registration correction, color correction, etc.). This gives
the information needed to identify causes and possible corrections.
Then involve operators in cause-effect analysis using "fishbone"
drawings to identify corrective measures. It usually boils down to a
need for better process control - through standard, documented setup
and press maintenence procedures, coupled with stated makeready
goals and a good feedback system for operators to let them know how
they're doing.
