Ni irihe tandukaniro rya RGB na CMYK mu gihe cy'imashini ikoresha inkjet?

Ni irihe tandukaniro rya RGB na CMYK mu gihe hariImashini ikoresha inkjet?

Ibara rya RGB ni amabara atatu y'ibanze y'urumuri. Umutuku, Icyatsi kibisi, n'Ubururu. Aya mabara atatu y'ibanze, afite ibipimo bitandukanye bishobora gukora amabara atandukanye. Mu by'ukuri, urumuri rw'icyatsi kibisi, umutuku n'ubururu rushobora guhuzwa n'andi mabara.

Nanone izwi nka KCMY, CMY ni mu magambo ahinnye y'umuhondo, cyan na magenta. Aya ni amabara agize intermediates muri RGB (amabara atatu y'ibanze y'urumuri) ahujwe mu mabara abiri ari yo ahuza RGB.

Mbere yuko twinjira mu bisobanuro birambuye, reka turebe ibi bikurikira:

Ku ishusho biragaragara ko ibara rya CMY ari ukuvanga ibice. Iri ni ryo tandukaniro rikomeye, none kuki icyuma cyacu gicapa amafoto na icyuma gicapa UV ari KCMY? Ibi biterwa nuko ikoranabuhanga riri gukoreshwa ubu ridashobora gukora amabara meza cyane. Uruvange rw'amabara atatu rushobora gutandukana gato n'umukara usanzwe, ariko ahubwo ni umutuku wijimye, bisaba ko habaho wino yihariye y'umukara ishobora kugabanya ubukana.

Mu buryo bw'imitekerereze, RGB mu by'ukuri ni ibara karemano, ari ryo bara riboneka mu bintu byose karemano dushobora kubona.

Muri iki gihe, agaciro k'amabara ya RGB kagaragara kuri ecran zishyirwa mu byiciro hakurikijwe amabara meza. Ibi biterwa nuko urumuri arirwo rwiza cyane, bityo ibara ryizewe neza rigaragaza agaciro k'amabara ya RGB. Bityo dushobora no gushyira amabara agaragara mu byiciro nk'amabara ya RGB.

Bitandukanye n'ibyo, amabara ya KCMY 4 agaragaza imiterere y'amabara yagenewe by'umwihariko gucapa mu nganda. Ntabwo agaragara cyane. Igihe cyose imiterere y'amabara icapishijwe ku bikoresho bitandukanye hakoreshejwe ibikoresho bigezweho byo gucapa. Uburyo bw'amabara bushobora gushyirwa mu byiciro hakurikijwe uburyo bwa KCMY.

Reka turebe itandukaniro rya RGB color mode , na KCMY color modes muri Photoshop:

(ubusanzwe igishushanyo mbonera kizagereranya itandukaniro riri hagati y'amabara abiri y'intego yo gucapa hifashishijwe ikoranabuhanga rya "rip printing")

Photoshop yashyizeho uburyo bubiri bw'amabara RGB na KCMY kugira ngo igaragaze itandukaniro. Mu by'ukuri, itandukaniro si rinini nyuma yo gucapa, ariko niba ifoto iri muri RIP hamwe na RGB, uzabona ko ibisubizo byo gucapa ari byinshi ugereranyije n'ifoto y'umwimerere.

Niba ushaka kumenya byinshi, ndakwinginzeTwandikire.
