Riso RZ 310 UI - Color Drum Question

Hello,

I have recently acquired a RZ 310UI and am anxious to get it up and running - I do not have much experience with Digital Duplicators but I have a basic understanding.

I am curious if there is a way to print multiple colors through one or two color drums.

I currently have a Forest Green, Red, and Medium Blue drums but was hoping to print in purple, yellow, and copper as well - is this impossible?

Any other insight about maintaining and proper use of a RZ unit would be greatly appreciated as well.

All the best,

PJ
