Nyuma y'imyaka hafi icumi ikoreshejwe, inki zivura za LED za UV zirimo gukoreshwa ku muvuduko wihuta n'abahindura amatara. Inyungu za wino ugereranije n'inki zisanzwe za UV za mercure - zikora neza kandi vuba, zinoze kandi zigabanya ikiguzi cyo kuzikoresha - zirimo gusobanuka cyane. Byongeye kandi, ikoranabuhanga riri kugenda ryoroha kuboneka kuko abakora imashini zitangaza batanga uburyo bwo gushyiramo amatara menshi aramba ku miyoboro yabo.
Byongeye kandi, hari impamvu ikomeye ku bahindura ikoranabuhanga (converters) yo gutekereza gukoresha LED, kuko ingaruka n'ikiguzi byo kubikora biri kugabanuka. Ibi birimo koroherezwa no kubona irangi rishya rya "dual cure" n'amabara ashobora gukoreshwa munsi y'amatara ya LED na mercure, bigatuma abahindura ikoranabuhanga bakoresha ikoranabuhanga mu ntambwe, aho gukoresha ikoranabuhanga mu buryo butunguranye.
Itandukaniro rikomeye riri hagati y'itara risanzwe rya mercure n'itara rya LED ni uburebure bw'umuraba butangwa kugira ngo habeho gushya. Itara rya mercure-vapor ritanga ingufu mu buryo buri hagati ya nanometero 220 na 400 (nm), mu gihe amatara ya LED afite uburebure bw'umurambararo buri hagati ya nanometero 375 na 410 kandi bugera ku gipimo cya 395 nm.
Inki za LED za UV zivurwa kimwe n'inki zisanzwe za UV, ariko zishobora kumva urumuri rugufi. Bityo, ziratandukanye bitewe n'itsinda ry'abakora fototikeri bakoreshwa mu gutangiza uburyo bwo kuvura; ibara, oligomer na monomer bikoreshwa ni bimwe.
Gukoresha UV LED mu gusukura ikirere bitanga inyungu zikomeye ku bidukikije, mu bwiza no mu mutekano kuruta gukoresha uburyo busanzwe bwo gusukura ikirere. Ubu buryo ntibukoresha mercure cyangwa ozone, bityo nta buryo bwo kuyikuramo bukenewe kugira ngo ikure ozone hafi y’imashini icapa.
Itanga kandi imikorere myiza mu gihe kirekire. Itara rya LED rishobora gukazwa no kuzimwa nta mpamvu yo gushyushya cyangwa gukonjesha, bigatuma rikora neza kuva ritangiye gukazwa. Nta mpamvu yo kurinda ibyuma birinda substrate iyo itara rizimye.
