Heidelberg 106 XL 16000 iPh non stop change over

This is a non-stop change over running 16000 iPh 28x40 60#. This day I was actually running 18000 in between change overs (was intense to say the least). Heidelberg is so user friendly . Press operator since 1990. ( started 1986 ). Very quick wash ups,make ready and run transition. And of course Heidelberg quality. Color holds great and tight registration.
