I was told by press service tech and personally agree - Kompac is a****s kicking system.
I think they call 3404 with kompacs + good platemaker a "DI buster".
Popkin and Co. tech told me "Want to be fancy - get a DI, want to make money get 3304 with kompacs"
I have a ABD 360CD with Kompac - it chews any ink, any brand, any type. My AB Dick Century 3500S has somewhat Crestline-like system and it is a lot more sensitive.
