Which UV inks you are using? Also what about Primer and Varnish?

Hi, what brand inks are you using?

I set a UV printer and got a kothari UV edition. Now this is a P800, so it has 8 channels. I am thinking to use CMYK WWW and Varnish. Should i use CMYK WW and Varnish*2 ? Is there a downside using varnish on same printhead?

Also at rip settings i see primer. So RIP supports a Primer layer, however i researched, everybody seems to use Primer with sprayer. Is there a UV curable, printhead compitable primer that i can use? If yes do you recommend it to go as CMYK WW Varnish and Primer setup?
