RGB inyaya yekuwedzera uye inosanganiswa nechiedza, CMYK ishoma uye inosanganiswa neiniki. Kushandura pakati pawo ndicho danho rinotorwa chero dhizaini yescreen isati yadhindwa.
Maitiro ekuverenga RGB kuenda ku CMYK
- Verenga R, G, B sekukosha kwesRGB pakati pe0 ne255.
- Tsvaga ruvara muprofaira yeCoated FOGRA39, profaira yeICC yakajairwa yebepa rakafukidzwa muEurope.
- Shandisa chinangwa chekuenzanisa mavara chine hukama pamwe nekugadzirisa poindi yedema, kuti chena chirambe chiri chena chebepa uye dema rishandurwe kuita inki yakasviba kupfuura dzose iyo muchina wekudhinda unogona kudhinda.
- Shandura ese mana value kuita percentages pakati pe0 ne100.
Muenzaniso wakashanda
Izvi zvinoshandisa profaira yakajairwa yeCoated FOGRA39. Zvitoro zvekudhinda zvinoshanda neprofaira dzazvo dzeICC nemirau yazvo yeinki, saka mamwe maprofaira eCMYK (semuenzaniso kubva kuchitoro chako chekudhinda) anopa manhamba akasiyana. Tora mhedzisiro sechinhu chekutarisa chakavimbika, kwete sekupatsanurwa kwemavara kwakagadzirira kudhindwa.
