Mutsara wekuti "kunze kwemuti" unoreva mavara akasiyana-siyana asingagoni kudzokororwa mukati me CMYK marara nzvimbo yakashandiswa pakudhinda. Graphics software yakagadzirirwa kushanda nemifananidzo muRGB ruvara rwemukati mukati mehutano hwekugadzirisa.
RGB ruvara rwemavara rine ruzivo rwakawanda rwemavara anooneka kupfuura CMYK inotsanangura kuti sei RGB mivara inowanzosviba painotamirwa ku CMYK. Kana iwe uchidhinda mufananidzo unofanirwa kuburitswa ne inks uye idzi inks haigoni kubereka mavara emhando imwechete yatinokwanisa kuona nemaziso edu nokuti RGB ruvara rweganda rinoshandisa chiedza, kwete pigment, kuti ribudise ruvara.
Nemhaka yekuti gamut yemuvara inogona kudzokororwa neingi yakawanda kudarika zvatinogona kuona, chero ruvara rusingazokwanisi kudzokororwa nein runotumidzwa se "kunze kwegutut." Mifananidzo yakashandura, iwe kazhinji uchaona kunze kwekuyeuchidza paunotarisa paunosarudza mavara achashanduka kana mufananidzo uchishandurwa kubva muRGB ruvara rwemavara inoshandiswa mukugadzirisa urongwa, kune nzvimbo ye CMYK inoshandiswa mukudhinda kwekutengeserana.
Mufananidzo uri pamusoro apa unokupa maonero akajeka ekunzwisisa gamut. Bhokisi rekunze ndiro rose raizivikanwa kumunhu wemazuva ano, kusanganisira yose yemavara atinogona kuona uye avo tisingakwanisi, zvakadai sa Ultraviolet uye Infrared.
Denderedzwa rokutanga ndeye mamiriyoni 16 mavara akawanikwa muRGB pavara pelelette uye mutsindo wemukati ndiyo yose mivara inogona kudhindwa nemichina yekudhinda. Icho chiri pakati, nokuda kwezvinangwa zvose uye zvinangwa, ibwe rakasviba. Kana iwe uchifamba kubva pakona yebhokisi kusvika padhesi, mavara anoita kuti ave nerima. Vanowedzera kuwedzera apo iwe uchienda kure.
Kana ukasarudza muvara muRGB gamut, ichange iine yakakodzana mu CMYK gamut asi, ine mutsauko. Kana ruvara rwunofamba rwakaenda kune iyo runoita kuti rive nerima.
