I need to implement ink marking on nickel and gold surfaces for IC 
components. Can anyone advise me on,

a.  Type of ink (for pad-mark)
b.  Surface pre-treatment process

that would ensure that the ink would meet the MIL-std mark permanancy test 
requirements ? Appreciate your expert advise !

Thanks
