icapiro rya UV

Mu myaka ya vuba aha, uburyo bwo gucapa bwateye imbere cyane. Iterambere rimwe rigaragara ni icapiro rya UV, rishingiye ku rumuri rwa ultraviolet mu gukangura wino. Muri iki gihe, icapiro rya UV riri kuboneka cyane kuko amasosiyete akoresha ikoranabuhanga rya UV arimo gutera imbere. Icapiro rya UV ritanga inyungu zitandukanye, kuva ku bwinshi bw'ibikoresho kugeza ku kugabanuka kw'igihe cyo gukora.

Ikoranabuhanga rya UV

Nk’uko izina ryayo ribisobanura, gucapa UV bishingiye ku ikoranabuhanga rya ultraviolet kugira ngo wino ivugururwe vuba. Nubwo inzira nyayo ari imwe n’ikoreshwa rya offset, hari itandukaniro rikomeye riri hagati ya wino ubwayo, ndetse n’uburyo bwo kuyimisha.

Uburyo busanzwe bwo gucapa hakoreshejwe inki zisanzwe zikoresha irangi risanzwe rikoresha inki zisanzwe zikoresha solvent zituma zumuka buhoro buhoro bitewe n’umwuka, zigatanga umwanya wo kwinjira mu mpapuro. Uburyo bwo kuzikuramo ni bwo butuma amabara adasa neza. Abacapa ibi babyita inyuma yumye kandi birushaho kugaragara cyane ku bicuruzwa bitarapfukwa.

Uburyo bwo gucapa UV bukoresha wino zidasanzwe zakozwe kugira ngo zimanuke kandi zivure iyo zihuye n'urumuri rwa ultraviolet ruri mu mashini. Wino za UV zishobora kuba zikomeye kandi zigatanga urumuri kurusha wino zisanzwe kuko nta gice cyumye kibaho. Iyo zimaze gucapwa, impapuro zihita zishyirwa mu gikoresho cyo gutanga ziteguye gukora ikindi gikorwa. Ibi bituma habaho imikorere myiza kandi akenshi bishobora kunoza igihe cyo gukora, hamwe n'imirongo isukuye kandi amahirwe make yo gushonga.
Ibyiza byo gucapa hakoreshejwe UV

Ubwoko bwagutse bw'ibikoresho byo gucapa

Impapuro za sintetike zikoreshwa cyane ku bikoresho bisaba ibikoresho birwanya ubushuhe mu gupakira no kwandikaho. Kubera ko impapuro na pulasitiki bya sintetike birwanya kwinjirwa, gucapa bisanzwe bya offset byasabye igihe kirekire cyumye. Kubera uburyo bwo kumisha ako kanya, gucapa hakoreshejwe UV bishobora kwakira ubwoko bwinshi bw'ibikoresho akenshi bidakwiranye n'iwino isanzwe. Ubu dushobora gucapa byoroshye ku mpapuro za sintetike, ndetse na pulasitiki. Ibi binafasha mu gusiga cyangwa gusya, bigatuma igishushanyo mbonera gishya kitagira inenge.

Kongera Kuramba

Mu gihe cyo gucapa hakoreshejwe uburyo busanzwe bwo gusohora amashusho, urugero nk'amafoto ya CMYK, amabara nk'umuhondo na magenta yahitaga ashira nyuma yo kwibasirwa n'izuba igihe kirekire. Ibi byatumaga amashusho asa n'umukara na cyan duo-tone, nubwo mbere yari afite amabara yuzuye. Amafoto n'ibindi bikoresho bishyirwa ku zuba ubu birinzwe na wino ivurwa n'urumuri rwa ultraviolet. Ingaruka ni ibicuruzwa biramba kandi bidashobora gushira byakozwe kugira ngo bimare igihe kirekire kurusha ibikoresho bisanzwe byacapwe.

Gucapa mu buryo butangiza ibidukikije

Icapiro rya UV naryo ntiringiza ibidukikije. Icapiro rya UV ntirigira uburozi bwangiza, bitandukanye na wino zimwe na zimwe zisanzwe. Ibi bigabanya ibyago byo kurekura ibintu bihumanya ikirere (VOCs) mu gihe cyo guhumeka. Muri Premier Print Group, duhora dushaka uburyo twagabanya ingaruka ku bidukikije. Iyi mpamvu yonyine ni imwe mu mpamvu zituma dukoresha icapiro rya UV mu bikorwa byacu.
