Abstract: Mu myaka yashize, icapiro ryamabara ya pantong ryakoreshejwe cyane mugucapura ibicuruzwa bipakira impapuro.Ibara rya pantong bivuga ibara ritari amabara ane hamwe nuruvange rwamabara ane, rwacapishijwe byumwihariko hamwe na wino yihariye.Pantong yamabara yo gucapa ikoreshwa mugupakira icapiro kugirango icapure ahantu hanini inyuma.Uru rupapuro rusobanura muri make ubuhanga bwo gucapa amabara ya pantong, ibikubiyemo byinshuti:

Icapiro ry'amabara ya pantong

Icapiro ryamabara ya pantong bivuga uburyo bwo gucapa aho andi mabara atari umuhondo, magenta, cyan na wino yumukara akoreshwa mugusubiramo ibara ryintoki zumwimerere.

Gupakira ibicuruzwa cyangwa ibifuniko byibitabo nibinyamakuru akenshi bigizwe nibice bimwe byamabara atandukanye cyangwa amabara asanzwe gahoro gahoro.Ibara ryamabara namagambo birashobora gucapishwa amabara ane yibanze nyuma yo kugabanwa mumabara, cyangwa amabara ya pantong arashobora kugabanwa, hanyuma wino imwe gusa yamabara ya pantong irashobora gucapishwa mumabara amwe.Mubisobanuro byuzuye byo kunoza ubuziranenge bwo gucapa no kuzigama umubare w’ibicapo, gucapa amabara ya pantong bigomba guhitamo.

1, Pantong ibara

Kugeza ubu, ibyinshi mu bikoresho byo mu rugo bipakira no gucapa mu gupima amabara ya antong no kugenzura bivuze ahanini gushingira ku bunararibonye bw'abakozi bwo gukoresha irangi rya pantong.Ikibi cyibi nuko igipimo cya wino ya pantong kidasobanutse neza, igihe cyo kohereza ni kirekire, ingaruka ziterwa nibintu bifatika.Ibigo bimwe bikomeye byo gupakira no gucapa byafashe sisitemu ya pantong ibara ihuza sisitemu yo kuyobora.

Sisitemu yo guhuza amabara ya pantong igizwe na mudasobwa, porogaramu ihuza amabara, spekitifotometero, impirimbanyi zisesenguye, igikoresho kimwe cya wino hamwe nigikoresho cyo kwerekana wino.Hamwe niyi sisitemu, ibipimo byimpapuro na wino bikunze gukoreshwa nisosiyete bikusanyirizwa mububiko, software ihuza ibara ikoreshwa muguhuza ibara ryibara ryatanzwe numukiriya mu buryo bwikora, hamwe nagaciro ka CIELAB, agaciro k'ubucucike na △ E gupimwa na spekitifotometero, kugirango amakuru yo gucunga ibara rya pantong ahuye wino irashobora kugerwaho.

2. Ibintu bigira ingaruka kumabara ya pantong

Mubikorwa byo gucapa, hari ibintu byinshi biganisha kuri chromatic aberration mubikorwa bya wino ya pantong.Izi ngingo zaganiriweho mu bice bikurikira.

Ingaruka yimpapuro kumabara:

Ingaruka yimpapuro kumabara ya wino igaragara cyane mubice bitatu

1) Impapuro zera: Impapuro zifite umweru utandukanye (cyangwa ufite ibara runaka) zigira ingaruka zitandukanye kumabara yerekana ibara ryanditse.Kubwibyo, mubikorwa nyirizina bigomba kugerageza guhitamo umweru umwe wo gucapa impapuro, kugirango ugabanye umweru wimpapuro kumabara.

2) gukuramo ubushobozi: wino imwe yacapishijwe mubihe bimwe kugirango ubushobozi butandukanye bwo gukurura impapuro, hazabaho gucapa ibintu bitandukanye.Impapuro zidatwikiriye hamwe nimpapuro zo kugereranya ugereranije, wino yumukara izagaragara imvi, yijimye, kandi irangi ryamabara bizana drift, hamwe na wino ya cyan na magenta wino bivanze nibikorwa byamabara biragaragara cyane.

3) kurabagirana no koroha: ububengerane bw'icapiro biterwa n'uburabyo n'ubwiza bw'impapuro.Ubuso bw'impapuro zo gucapa ni igice cyuzuye-gloss, cyane cyane impapuro.

Ingaruka zo kuvura hejuru kumabara:

Kuvura hejuru yibicuruzwa bipfunyika byuzuyemo firime (firime yoroheje, firime ya matt), gusiga (gutwikira amavuta yoroheje, amavuta ya matati, UV varnish) nibindi.Ibicapo nyuma yubu buryo bwo kuvura, hazaba impinduka zitandukanye za hue ihinduka nubucucike bwamabara.Gupfuka firime nziza, gutwikira amavuta meza hamwe namavuta ya UV, ubwinshi bwamabara bwiyongera;Iyo utwikiriye firime ya matte hanyuma ugapfundikira amavuta ya matte, ubwinshi bwamabara buragabanuka.Imihindagurikire yimiti ituruka cyane cyane kuri kole, amavuta ya UV, amavuta ya UV arimo ibinyabuzima bitandukanye byumuti, bizatuma ibara ryibara ryandika rihinduka.

Ingaruka zo gutandukanya sisitemu:

Ikozwe mugukwirakwiza ibikoresho, erekana ibara rya wino "inzira yumye", inzira yo kwitabira, nta mazi no gucapa ni "progaramu yo gucapa", amazi yatose agira uruhare mugucapura, bityo muri offset yo gucapa wino byanze bikunze bizabera amazi-y-amavuta-emulsion, wino ya emulsiya kubera guhinduka nyuma yo gukwirakwiza imiterere yibice bya pigment murwego rwa wino, byanze bikunze bitanga ibara, ibicuruzwa byacapwe nabyo ni ibara ryijimye, ntabwo ryaka.

Mubyongeyeho, itandukaniro rya desalinator nubucucike bwa desalinator bwagize ingaruka runaka kumabara.Ihinduka rya wino ryakoreshejwe mu kuvanga ibara rya pantong, ubunini bwurwego rwa wino, ubunyangamugayo bwa wino ipima, itandukaniro riri hagati y’ahantu hahoze hashyirwaho wino hashyizweho imashini icapura, umuvuduko w’imashini icapa, na ubwinshi bwamazi kumashini yandika nayo azagira ingaruka zitandukanye kubitandukaniro ryamabara.

3, Kugenzura amabara ya Pantong

Mu ncamake, kugirango tumenye neza ko itandukaniro ryibara ryicyiciro kimwe nibice bitandukanye byibicuruzwa byujuje ubuziranenge bwigihugu nibisabwa nabakiriya, ibara rya pantong rigenzurwa kuburyo bukurikira mugucapa:

Gukora ikarita y'amabara ya pantong

Ubwa mbere, ukurikije amabara asanzwe yatanzwe nabakiriya, ukoresheje sisitemu yo guhuza ibara rya mudasobwa kugirango utange igipimo cya wino y'amabara ya pantong;Noneho hanze yicyitegererezo, hamwe nigikoresho kimwe cya wino, igikoresho cyo kwerekana wino "kwerekana" ubucucike butandukanye bwikitegererezo;Noneho ukurikije ibipimo ngenderwaho byigihugu (cyangwa umukiriya) kumurongo wibara ryibisabwa bisabwa murwego, hamwe na spekitifotometero kugirango umenye ibipimo ngenderwaho, imipaka ntarengwa, imipaka yimbitse, icapiro ryamabara asanzwe (itandukaniro ryibara rirenze ibisanzwe bigomba gukosorwa).Kimwe cya kabiri cyikarita yamabara nicyitegererezo cyibara risanzwe, ikindi gice nubuso bwakorewe ibara ryicyitegererezo, ibi nukworohereza ikoreshwa ryigenzura ryiza.

Kugenzura ibara

Urebye ko impapuro aricyo kintu cyingenzi kigira ingaruka ku itandukaniro ryibara, bityo rero mbere yo gucapa kugirango ukoreshe impapuro zicapiro "kwerekana" icyitegererezo cyamabara, ikarita yerekana ibara kugirango ikore micro-ikosora, kugirango ikureho ingaruka zimpapuro.

Igenzura

Imashini yo gucapa ikoresha icapiro ryamabara asanzwe kugirango igenzure ubunini bwurupapuro rwamabara ya pantong, kandi ifasha gupima agaciro gakomeye nigiciro cya BK cyamabara hamwe na densitometero kugirango batsinde itandukaniro ryubwinshi bwamabara yumye kandi atose.

Muri make, mugupakira icapiro, hariho impamvu zitandukanye zo guta amabara ya pantong.Birakenewe gusesengura impamvu zinyuranye mubikorwa nyabyo, gukemura ibibazo, kugerageza kugenzura gutandukana kurwego ruto, no kubyara ibicuruzwa byapakiye bishimisha abakiriya.
