Ibara rifite umwanya wingenzi mu icapiro, rikaba ari ikintu cyingenzi gisabwa kugira ngo umuntu agaragaze ingaruka kandi agaragare, kandi ni ibintu bitangiza ibintu bikurura abakiriya ndetse bikanatuma bagura.
Buri bara ryibara rihuye na wino idasanzwe (usibye umuhondo, magenta, cyan, umukara), igomba gucapwa nigice cyihariye cyo gucapa.Hariho impamvu nyinshi zituma abantu bakoresha amabara yibibara muriicapiro, kwerekana ishusho yikigo cyisosiyete (nkumutuku wa Coca-Cola cyangwa ubururu bwa Ford) nimwe murimwe, niba rero ibara ryibara rishobora kubyara neza ntacyo bitwaye kubakiriya cyangwa kubakiriya.Ni ngombwa ku icapiro.Indi mpamvu irashobora kuba ikoreshwa rya wino.Irangi ryuma risanzwe ririmo ibice bimwe byuma kandi birashobora gutuma icapiro rigaragara nkicyuma.Mubyongeyeho, mugihe ibara risabwa mubishushanyo byumwimerere birenze ibara rya gamut urwego rushobora kugerwaho numuhondo, cyan, numukara, dushobora kandi gukoresha amabara yibibara kugirango twuzuze.
Guhindura amabara
Iyo duhinduye ibara ryishusho kuva RGB kuri CMYK, mubisanzwe hariho uburyo bubiri bwo kubyara utudomo twa halftone ya wino yumukara, bumwe buri munsi yo gukuraho amabara (UCR), naho ubundi ni ibara risimbuza ibara (GCR).Nubuhe buryo bwo guhitamo buterwa ahanini nubunini bwumuhondo, magenta, cyan na wino yumukara bizacapwa mumashusho.
"Gukuraho ibara ry'inyuma" bivuga gukuraho igice cy'ibara ry'imyenda idafite aho ibogamiye ku mabara atatu y'ibanze y'umuhondo, magenta, na cyan, ni ukuvuga, ibara ry'umukara ryirabura ryakozwe no hejuru y'amabara atatu y'ibanze y'umuhondo, magenta , na cyan, no kuyisimbuza wino y'umukara..Gukuraho gukuramo cyane cyane bigira ingaruka ku gicucu cyibishusho, ntabwo ari amabara.Iyo ishusho itunganijwe nuburyo bwo gukuraho ibara ryinyuma, biroroshye kugaragara ibara ryakozwe mugihe cyo gucapa.
Gusimbuza ibara ryibara risa no gukuraho ibara ryinyuma, kandi byombi bikoresha wino yumukara kugirango bisimbuze imvi zakozwe mugushushanya irangi ryamabara, ariko itandukaniro nuko ibara ryimyenda risimbuza bivuze ko ibara ryimyenda murwego rwose rwa tone rishobora gusimburwa n'umukara.Kubwibyo, iyo ibara ryimyenda isimbuwe, ingano ya wino yumukara iba nto cyane, kandi ishusho icapishwa cyane na wino yamabara.Iyo umubare ntarengwa wo gusimbuza wakoreshejwe, ingano ya wino yumukara nini nini, kandi ingano ya wino yamabara iragabanuka.Amashusho yatunganijwe hamwe nuburyo bwo gusimbuza ibara risa neza mugihe cyo gucapa, ariko ingaruka zazo nazo ziterwa ahanini nubushobozi bwabakozi bashinzwe itangazamakuru kugirango bahindure ibara.
