Uhlobo lwe-inki olunyangwa kukuvezwa kukukhanya kwe-UV.Isithuthi kwezi inki iqulethe ubukhulu becala monomers kunye abaqalisi.I-inki isetyenziswa kwi-substrate kwaye emva koko ibonakaliswe kukukhanya kwe-UV;abaqalisi bakhupha ii-athomu ezisebenzayo kakhulu, ezibangela ukuba i-polymerisation ekhawulezileyo yee-monomers kunye neeseti ze-inki zibe yifilimu enzima.Ezi inki zivelisa umgangatho ophezulu kakhulu woshicilelo;bayomisa ngokukhawuleza ukuba akukho nanye inki ifunxa kwi-substrate kwaye ke, njengoko ukunyangwa kwe-UV kungabandakanyi iindawo ze-inki eziphumayo okanye zisuswe, phantse i-100% ye-inki iyafumaneka ukwenza ifilimu.
