Ink bụ isi iyi mmetọ kasịnụ nke ụlọ ọrụ obibi akwụkwọ; ihe ink na-emepụta kwa afọ n'ụwa eruola nde tọn atọ. Ihe mmetọ mmetọ nke ink na-ebute kwa afọ n'ụwa niile ruru ọtụtụ narị puku tọn. Ndị a organic volatiles nwere ike na-etolite ọzọ njọ griin haus mmetụta karịa carbon dioxide, na n'okpuru irradiation nke ìhè anyanwụ ga-etolite oxides na photochemical anwụrụ ọkụ, oké njọ mmetọ nke ikuku gburugburu ebe obibi, na-emetụta ndị mmadụ ike. Ugbu a, isiink nchedo gburugburu ebe obibinwere ụdị ndị a:
1) Ink dabeere na mmiri
Ink dabeere na mmiri na-eji mmiri karịa ihe mgbaze organic, nke na-ebelata oke ikuku VOC ma ghara imetụta ahụike mmadụ. Ọ dịghị mfe ọkụ, ink kwụsiri ike, agba na-egbuke egbuke, anaghị emebi efere ahụ, ọrụ dị mfe, ọnụ ala dị ọnụ ala, ezigbo adhesion mgbe e bipụtachara, mmiri siri ike na-eguzogide, ihicha ngwa ngwa. Ọ bụ ihe obibi obibi nchekwa gburugburu ụwa amaara ama.
2) UV ink curable
Ink UV na-ezo aka n'iji ọkụ UV, nwere ogologo ebili mmiri na ike dị iche iche n'okpuru irradiation UV iji mee ihe nkiri ink ọgwụgwọ. Iji uv spectral ume, ihe nkedo ink na polymerization nke monomers n'ime polymers, Ya mere, ihe nkiri agba ink UV nwere ezigbo ihe eji arụ ọrụ na kemịkal.
