Igishushanyo cyibara ryibishushanyo mbonera byumuyaga bigizwe nibintu bitatu byibanze: pigment cyangwa irangi, umutwara ninyongera.Ni ubwinshi bwa pigment cyangwa irangi bifatanye kimwe na resin, bityo imbaraga zayo zo kurangi zisumba pigment ubwayo.Kugirango tunoze imbaraga zo gukwirakwiza no gusiga amabara, pigment igomba gutunganywa mugikorwa cyo gutunganya ibicuruzwa.Umwikorezi wa masterbatch ni kimwe nubwoko bwa plastiki bwibicuruzwa, bihuye neza, kandi ibice bya pigment birashobora gukwirakwizwa neza muri plastiki yibicuruzwa nyuma yo gushyushya no gushonga.Bitewe na pigment mugikorwa cyo kubika no gukoresha imikoreshereze itaziguye n'umwuka, pigment ikurura amazi, ibintu nka okiside, bizabaho kubabaza nyina wumwamikazi, kubera ko umutwaro utwara amarangi uzasiga irangi hamwe numwuka hamwe n’amazi, bishobora gutuma u ubwiza bwirangi ntugahinduke uduce twa mama nuburakari hafi yigihe kinini, byoroshye kandi byukuri mugupima, kuvanga ntibizaguma kuri kontineri, kandi kuvanga resin birasa, Kubwibyo, birashobora kwemeza ituze ryamafaranga yongeweho, kugirango tumenye neza ibara ryibicuruzwa.
