Inki ndiye gwero lalikulu kwambiri loipitsa makampani osindikizira; kutulutsa kwapachaka kwa inki kwafika matani 3 miliyoni. Kutulutsa kwapachaka kwapachaka kwa organic organic volatile matter (VOC) komwe kumachitika chifukwa cha inki kwafika matani mazana masauzande. Izi organic volatiles akhoza kupanga kwambiri wowonjezera kutentha kwenikweni kuposa mpweya woipa, ndi pansi kuunika kwa dzuwa kupanga oxides ndi photochemical utsi, kwambiri kuipitsa mumlengalenga, zimakhudza thanzi la anthu. Pakali pano, chachikuluInki yoteteza chilengedweili ndi mitundu iyi:

 1) Inki yokhala ndi madzi

Inki yopangidwa ndi madzi imagwiritsa ntchito madzi m'malo mosungunulira organic, zomwe zimachepetsa kwambiri mpweya wa VOC ndipo sizikhudza thanzi la munthu. Sikophweka kuwotcha, inki yokhazikika, mtundu wowala, sichiwononga mbale, ntchito yosavuta, mtengo wotsika mtengo, kumamatira bwino pambuyo pa kusindikiza, kukana madzi amphamvu, kuyanika mofulumira. Ndi dziko anazindikira chilengedwe chitetezo kusindikiza zakuthupi.

 2) Inki yochiritsira ya UV

Inki ya UV imatanthawuza kugwiritsa ntchito kuwala kwa UV, kokhala ndi kutalika kosiyanasiyana ndi mphamvu pansi pa kuwala kwa UV kuti apange filimu ya inki kuchiritsa. Pogwiritsa ntchito mphamvu ya UV spectral, chomangira inki mu polymerization ya ma monomers kukhala ma polima, Chifukwa chake filimu ya inki ya UV imakhala ndi makina abwino komanso mankhwala. Pakali pano inki ya UV yasanduka ukadaulo wokhwima kwambiri wa inki, zomwe zimaipitsa ndizochepa kwambiri. Kuphatikiza pa kulibe zosungunulira, inki ya UV ndiyosavuta kuyika, kadontho kowoneka bwino, mtundu wowala, kukana kwamphamvu kwamankhwala, kumwa, ndi zabwino zina.

 3) Inki yochokera ku soya

Inki yopangidwa ndi soya imapangidwa ndi mafuta odyedwa a soya (kapena mafuta ena owuma kapena owuma a masamba) osakanikirana ndi inki, utomoni, sera ndi zina zotero. Inkiyi ilibe zinthu zosasunthika zomwe zimawononga mlengalenga, zopanda fungo, zopanda poizoni, zimasintha pang'onopang'ono inki yamafuta amchere. Kutchuka kwake ndi kukwezedwa kwake kumathamanga kwambiri ku Europe, Japan ndi United States.

 4) Inki ya UV yamadzi

Inki yochokera m'madzi ya UV ili mu inki ya UV yowonjezera madzi ena ndi 5%kuteteza chilengedwezosungunulira, kuphatikizapo utomoni wapadera madzi. Izi zimapangitsa kuti inkiyi isangokhala ndi ubwino wa kuchiritsa kwa inki ya UV mofulumira, kupulumutsa mphamvu, kupondaponda pang'ono, kuteteza chilengedwe, komanso kukwaniritsa machiritso a inki, kusungunuka kwa chinyezi, kotero kuti wosanjikiza inki kupatulira zofunika kusindikiza. Inki iyi ndi njira yatsopano yofufuzira pankhani ya inki ya UV.

5) Inki yosungunuka mowa

Mowa-sungunuka inki zachokera Mowa (mowa) monga zosungunulira waukulu, sanali poizoni, otetezeka, kuteteza chilengedwe, thanzi, ndi m'malo abwino mankhwala inki pulasitiki chikhalidwe. Ku South Korea, Singapore, inki yosungunuka mowa yalowa m'malo mwa inki ya toluene. Inki yosungunuka moŵa imagwira ntchito kwambiriflexondi inki yothandiza zachilengedwe.
