Umbala uthatha isikhundla esibalulekile ekunyatheliseni, okuyimfuneko ebalulekile ukuze uthole umthelela obonakalayo nokukhanga, kanye nento enembile eheha ukunaka kwabathengi futhi ibangele nokuthenga.
Umbala webala ngalinye uhambisana noyinki okhethekile (ngaphandle kophuzi, i-magenta, i-cyan, emnyama), okudingeka ukuthi iphrintwe iyunithi yokuphrinta ehlukile emshinini wokunyathelisa.Kunezizathu eziningi zokuthi kungani abantu basebenzisa imibala yamabala kuphrinta, ukugqamisa isithombe somkhiqizo wenkampani (okubomvu kwe-Coca-Cola noma okuluhlaza okwesibhakabhaka kwe-Ford) kungenye yazo, ngakho-ke ukuthi umbala wamabala ungaphinda ukhiqizwe ngokunembile ngeke kube nandaba kumakhasimende noma kumakhasimende.Ibalulekile endlini yokuphrinta.Esinye isizathu kungaba ukusetshenziswa inki metallic.Oyinki bensimbi ngokuvamile baqukethe izinhlayiya ezithile zensimbi futhi bangenza okubhaliwe kubonakale kuyinsimbi.Ngaphezu kwalokho, lapho izimfuneko zombala zomklamo wangempela zidlula ububanzi be-gamut yombala engafinyelelwa ngokuphuzi, okusasibhakabhaka, nokumnyama, singaphinda sisebenzise imibala yamabala ukuze singezelele.
ukuguqulwa kombala
Uma siguqula umbala wesithombe usuka ku-RGB uye ku-CMYK, ngokuvamile kunezindlela ezimbili zokwenza amachashazi ayi- halftone kayinki omnyama, eyodwa ingaphansi kokukhishwa kombala (UCR), kanti enye i-grey component replacement (GCR).Iyiphi indlela ongayikhetha incike kakhulu enanini leziyinki eziphuzi, ze-magenta, ze-cyan nezimnyama ezizophrintwa esithombeni.
“Ukususwa kombala ongemuva” kubhekisela ekukhipheni ingxenye yombala wengemuva ompunga ophakathi nendawo emibaleni emithathu eyinhloko yophuzi, i-magenta, ne-cyan, okungukuthi, umbala wangemuva ocishe umnyama owenziwe ukuphakama kwemibala emithathu eyinhloko yophuzi, i-magenta. , kanye ne-cyan, futhi esikhundleni salo ufake uyinki omnyama..Ukususwa kwethoni ephansi kakhulu kuthinta izindawo zethunzi zesithombe, hhayi izindawo ezinemibala.Uma isithombe sicutshungulwa ngendlela yokukhipha umbala wangemuva, kulula ukuvela umbala ofakwe phakathi nenqubo yokuphrinta.
Ukushintshwa kwengxenye empunga kufana nokususwa kombala wangemuva, futhi bobabili basebenzisa uyinki omnyama ukuze bamiselele okumpunga okwakhiwa ngokuphrinta ngokweqile uyinki wombala, kodwa umehluko ukuthi ukushintshwa kwengxenye empunga kusho ukuthi izingxenye ezimpunga kulo lonke uhla lwethoni zingashintshwa. ngomnyama.Ngakho-ke, lapho ingxenye empunga ishintshwa, inani likayinki omnyama lincane kakhulu, futhi isithombe sinyatheliswa ngokuyinhloko ngoyinki wombala.Uma kusetshenziswa inani eliphezulu lokushintshwa, inani likayinki omnyama likhulu kakhulu, futhi inani likayinki wombala liyancishiswa ngokufanayo.Izithombe ezicutshungulwe ngendlela yokushintsha ingxenye empunga zizinzile kakhulu ngesikhathi sokuphrinta, kodwa umphumela wazo uncike kakhulu ekhonweni lika-opharetha wokushicilela ukulungisa umbala.
