Inkingi nikintu cyingenzi muburyo butandukanye bwo gucapa, kandi ubwoko butandukanye bwa wino bukoreshwa kugirango tugere ku ngaruka zihariye. Ibidukikije byangiza ibidukikije, wino ya solvent, hamwe na wino ishingiye kumazi nubwoko butatu bukunze gukoreshwa, buri kimwe gifite umwihariko wacyo hamwe nibisabwa. Reka dusuzume itandukaniro riri hagati yabo.
Irangi rishingiye kumazi ni uburyo buboneka kandi bwangiza ibidukikije. Igizwe na pigment cyangwa amarangi ashonga mumazi. Ubu bwoko bwa wino ntabwo ari uburozi kandi burimo VOC nkeya (ibinyabuzima bihindagurika), bigatuma ikoreshwa neza mubidukikije. Irangi rishingiye kumazi rikoreshwa cyane mugucapisha ibiro, gucapa ibihangano byiza, gucapa imyenda nibindi bikorwa.
Ku rundi ruhande, wino ya solvent, igizwe na pigment cyangwa amarangi yashonze mu binyabuzima bihindagurika cyangwa peteroli. Iyi wino iraramba cyane kandi itanga neza cyane kubintu bitandukanye birimo vinyl, plastike nicyuma. Irangi rya solvent rikoreshwa mubimenyetso byo hanze no gufunga ibinyabiziga kuko birwanya ibihe bibi kandi bitanga ibisubizo birebire byo gucapa.
Irangi rya eco-solvent ni wino igereranije ifite imiterere hagati yamazi ashingiye kumazi. Igizwe nuduce duto twa pigment yahagaritswe mumashanyarazi yangiza ibidukikije, arimo VOC yo hasi kuruta wino gakondo. Irangi ryangiza ibidukikije ritanga imbaraga zirambye hamwe nimikorere yo hanze mugihe bitangiza ibidukikije. Bikunze gukoreshwa mubisabwa nko gucapa banneri, ibishushanyo bya vinyl, hamwe nurukuta.
Kimwe mubitandukaniro nyamukuru hagati yubwoko bwa wino nuburyo bwo gukiza. Irangi rishingiye kumazi ryumye no guhumeka, mugihe wino ishingiye kumashanyarazi hamwe nibidukikije byangiza ibidukikije bisaba igihe cyo kumisha hifashishijwe ubushyuhe cyangwa kuzenguruka ikirere. Iri tandukaniro mugikorwa cyo gukiza rigira ingaruka kumuvuduko wo gucapa hamwe nubuhanga bwibikoresho byo gucapa.
Byongeye kandi, guhitamo wino biterwa nibisabwa byihariye byumushinga wo gucapa. Ibintu nko guhuza ubuso, imikorere yo hanze, amabara meza hamwe nibidukikije bigira uruhare runini muguhitamo ubwoko bwa wino.
Muri rusange, wino ishingiye kumazi ninziza kubidukikije byangiza ibidukikije mu nzu, mugihe wino ya solvent itanga igihe kirekire kubikorwa byo hanze. Irangi ryangiza ibidukikije ryerekana uburinganire hagati yigihe kirekire nibidukikije. Gusobanukirwa itandukaniro riri hagati yubwoko bwa wino butuma icapiro rihitamo neza ukurikije ibyo bakeneye byo gucapa no kwiyemeza ibidukikije.
