Phantse ishumi leminyaka emva kokwaziswa kwabo, ii-inks ze-UV ezinyangekayo ze-UV zamkelwa ngesantya esikhawulezileyo ngabaguquli beelebhile. Izibonelelo ze-inki ngaphezulu kwe-inks 'eqhelekileyo' ye-UV-inyango engcono kwaye ekhawulezayo, ukugcinwa okuphuculweyo kunye neendleko eziphantsi zokusebenza - ziya ziqondwa ngokubanzi. Ukongezelela, iteknoloji ifikeleleka ngokulula njengoko abavelisi beendaba banikezela ukubandakanya uluhlu olubanzi lwezibane zobomi obude kwimigca yabo.
Ngaphezu koko, kukho inkuthazo enkulu kubaguquli ukuba bacinge ngokutshintshela kwi-LED, kuba iingozi kunye neendleko zokwenza oko ziyancipha. Oku kuququzelelwa kukufika kwesizukulwana esitsha 'sonyango oluphindwe kabini' ii-inki kunye neengubo ezinokuqhutywa phantsi kwezibane ze-LED kunye ne-mercury, ezivumela abaguquli ukuba bamkele iteknoloji ngokwamanyathelo, kunokuba ngequbuliso.
Umahluko ophambili phakathi kwesibane semercury esiqhelekileyo kunye nesibane se-LED ngamaza obude akhutshwayo ukuze kunyangelwe ukuba kwenzeke. Isibane somphunga wemercury sisasaza amandla phakathi kwe-220 kunye nama-400 nanometers (nm), ngelixa izibane ze-LED zinobude obumxinwa phakathi kwe-375nm kunye ne-410nm kwaye ziphezulu malunga ne-395nm.
Iinki ze-UV ze-UV zinyangwa ngendlela efanayo nee-inks ze-UV eziqhelekileyo, kodwa zinovelwano kubude obumxinwa bokukhanya. Bahluke omnye komnye, ngoko ke, liqela leefotonitiators ezisetyenziselwa ukuqalisa ukusabela kokunyanga; ii-pigments, ii-oligomers kunye ne-monomers ezisetyenzisiweyo ziyafana.
Ukunyangwa kwe-UV LED kunika indalo eyomeleleyo, umgangatho, kunye neenzuzo zokhuseleko ngaphezu kokunyanga okuqhelekileyo. Inkqubo ayisebenzisi i-mercury okanye i-ozone, ngoko akukho nkqubo yokukhutshwa iyadingeka ukususa i-ozone ukusuka kumatshini wokushicilela.
Ibonelela ngobuchule bexesha elide ngokunjalo. Isibane se-LED sinokuvulwa kwaye sicinywe ngaphandle kwesidingo sokufudumeza okanye ukupholisa ixesha, ukubonelela ngentsebenzo efanelekileyo ukususela ngoku silayitayo. Akukho mfuneko yee-shutters ukukhusela i-substrate ukuba isibane sicinyiwe.
