Umhleli we umatshini wokushicilela wesikrini umenzi uya kukucacisela izakhono zokulondolozwa komthombo wokukhanya kwe-UV kunye nezixhobo kushicilelo lwe-UV lomatshini wokushicilela wesikrini izixhobo ezixhasayo.
Isixhobo sokushicilela umatshini wokushicilela wesikrini umatshini wokunyanga we-UV, ukusetyenziswa kwe-inki ye-UV okanye ivanishi ye-UV inokubangela ukuba ingubo yerola ye-inki yoshicilelo okanye ipleyiti yomnwe womthi idumbe. Ukudumba okumandla kuya kubangela ukuxobuka okanye ukuqhekeka komhlaba. Kubaluleke kakhulu ukusebenzisa irabha ekhethiweyo kunye neepleyiti zeminwe yomthi.
Uninzi lwababoneleli be-ink ye-UV baya kuncoma uluhlu lokusetyenziswa, njengengubo ye-nitrification okanye izinto zonyango ze-nitrification zinokudibaniswa ne-oil UV inki kunye ne-varnish; ngelixa izinto zerabha zendalo kunye ne-polyethylene ziya kukhula, azifanelekanga i-UV inki kunye ne-varnish; Izinto zerabha ze-EPDM zilungele ngokukodwa i-UV inki kunye nevanishi, kodwa ayifanelekanga kwi-inki jikelele. I-inki roller yomatshini wokushicilela isikrini nayo isekelwe kulo mgaqo. Akuqhelekanga ukuba utshintshele kwi-inki ye-UV kunye ne-oyile ngokubanzi. Ukuba kufuneka itshintshwe, kufuneka icocwe ukuze kususwe zonke iikhemikhali ezishiyekileyo.

Ngokuqhelekileyo, uhlobo lomatshini wokushicilela kufuneka luthathelwe ingqalelo xa ufaka izibane ze-UV. I-BASF UV ii-inks kunye neevanishi zisebenzisa izibane zemercury ezicinezelayo okanye iibhalbhu ze-microwave H ezilungele ukusetyenziswa kwimizi-mveliso. Ukuba owokuqala ngumbala omnye, kufuneka kusetyenziswe iiglowubhu zemercury ezimbini ezikwi-120w/cm zoxinzelelo oluphakathi. Ngokuqhelekileyo, ubunzima bokomisa i-inki ye-UV enemibala emine yi-magenta, i-yellow-cyan, kunye nomnyama ngokulandelelana. Ke ngoko, iodolo yoshicilelo lwemibala ye-UV kufuneka ibe mnyama, cyan, tyheli, kunye nemagenta.
Kunzima kakhulu ukuxuba eminye imibala. Umzekelo, uhlaza lwenziwe ngotyheli kunye necyan. Ukongeza, kunzima ukuxuba imibala e-opaque kuba ibonakalisa konke ukukhanya kwe-UV ngasemva. Ingxaki efanayo ikhona kwimibala yesinyithi, igolide, kunye nesilivere efanayo.
Isibane se-UV mercury sinobomi obuthile, ityhubhu yesibane endala kakhulu ayinakomisa i-ink ye-UV okanye ivanishi. Uninzi lwemiyalelo yesibane se-UV ibonisa ukuba isibane se-UV kufuneka sitshintshwe emva kokusetyenziswa kweeyure ezimalunga ne-1,000. Kwimveliso yokwenyani, ukuba unoluvo lokuba into eprintiweyo ayinakomiswa ngesantya esiqhelekileyo sokushicilela, kuya kufuneka ucinge ngokutshintsha isibane se-UV.
Ukuba i-reflector ayifakwanga, malunga ne-80% yesibane se-UV asiyi kukwazi ukwenza into eprintiweyo ngenxa yokusabalalisa, ngoko isibane se-UV kufuneka sifakwe kunye nomthunzi wesibane ukuze sibonise kwaye sigxininise kwicala lomba oshicilelweyo. . Balingane, isibonisi kufuneka sicocwe kwaye sigcinwe nangaliphi na ixesha. Ukuba uthuli lwephepha okanye uthuli olusuka kwi-powder yokutshiza lunamathela kwisibonisi, luya kuchaphazela umphumo wokubonakalisa isibane se-UV; ukuba isibane se-UV asisetyenziswanga ixesha elide, isibane sesibane se-UV kufuneka sivalwe kwakhona ukuthintela uthuli ukuba lungangeni.
Oku ngasentla kubuchule bokugcinwa komthombo wokukhanya kwe-UV kunye nezixhobo kushicilelo lwe-UV oluhambelana nomatshini wokushicilela wesikrini.
