water resistant ink

[etiqrams]

hi, i am trying to fin out, is their anything on the market, that can be add to the ink, on any riso or duplo duplicator, since i need that my prints be water resistant.
like hp mc6080 that has aditional bonding agent, and really helps to improve water and acratch resistant. and possible to use a cylinder with this type of varnish or transparent ink to help my problem. thanks

Just a UV or AQ coating is my guess.
