Start out at where you nomally do and go from there. With metallic there is always a little problem. You would want to run it heavier to get it to look metallic. If you do watch out for scumming. Bring up the water to keep things open and clean. For some reason metallic inks when running heavy. the metering roller wants to pickup ink. Keep an eye on that. Metallic inks want to scuff if you don't varnish or coat it. Sometimes when you varnish and coat it you'll lose some of the metallic flake look in the ink.
