A na-eji ink sitere na mmiri eme ihe n'ibipụta akwụkwọ corrugated ruo ogologo oge ná mba ọzọ na ruo ihe karịrị afọ 20 n'ụlọ. Mbipụta akwụkwọ corrugated amalitela site na mbipụta lead (mbipụta enyemaka), mbipụta offset (mbipụta offset) na mbipụta rọba nke a na-asacha mmiri ruo na mbipụta ink dabere na mmiri nke taa. Ink sitere na mmiri nke a na-agbanwe agbanwe agbanwe etolitela site na usoro resin rosin-maleic (ọkwa dị ala) gaa na usoro resin acrylic (ọkwa dị elu). Efere mbipụta ahụ na-agbanwekwa site na efere roba gaa na efere resin. Igwe mbipụta ahụ etolitekwala nwayọ nwayọ site na igwe mpịakọta otu agba ma ọ bụ agba abụọ nwere nnukwu mpịakọta gaa na igwe mpịakọta FLEXO agba atọ ma ọ bụ agba anọ.
Ihe mejupụtara na njirimara nke ink ndị e ji mmiri mee bụ otu ihe ahụ dị ka nke ink ndị e ji ebi akwụkwọ n'ozuzu. Ink ndị e ji mmiri mee na-abụkarị agba, ihe e ji ejikọta ihe, ihe enyemaka na ihe ndị ọzọ. Ihe e ji agba agba bụ agba nke ink ndị e ji mmiri mee, nke na-enye ink ahụ agba pụrụ iche. Iji mee ka mmetụta ahụ na-egbuke egbuke na mbipụta flexographic, ihe e ji agba agba na-ejikarị agba nwere ezigbo nkwụsi ike kemịkalụ na ike agba dị elu; ihe e ji agba ya bụ mmiri, resin, ihe ndị e ji amine mee na ihe ndị ọzọ e ji mmiri mee. Resin bụ ihe kachasị mkpa na ink ndị e ji mmiri mee. A na-ejikarị resin acrylic nke na-agbaze mmiri. Ihe e ji agba ya na-emetụta ọrụ njikọ, ọsọ nkụ, arụmọrụ mgbochi ịrapara, wdg. nke ink, ma na-emetụtakwa nnyefe ink na-egbuke egbuke. Ihe e ji amine mee na-ejigide uru PH alkaline nke ink ndị e ji mmiri mee, ka resin acrylic nwee ike inye mmetụta mbipụta ka mma. Mmiri ma ọ bụ ihe ndị ọzọ e ji mmiri mee bụ resin ndị a gbazere agbaze, Hazie viscosity na ọsọ nkụ nke ink; Ihe ndị na-enye aka gụnyere: defoamer, blocker, stabilizer, diluent, wdg.
Ebe ọ bụ na ink e ji mmiri mee bụ ihe mejupụtara ncha, ọ dị mfe imepụta afụfụ a na-eji, yabụ a ga-etinye mmanụ silicone dị ka ihe na-egbochi ma wepụ afụfụ, ma melite arụmọrụ nnyefe nke ink. A na-eji ihe mgbochi egbochi ọsọ nkụ nke ink e ji mmiri mee, gbochie ink ka ọ kpọọ nkụ na mpịakọta anilox ma belata pasta. Ihe na-eme ka ihe kwụsie ike nwere ike ịgbanwe uru PH nke ink ahụ, enwere ike iji ya dị ka ihe na-agbaze iji belata viscosity nke ink ahụ. A na-eji ihe na-agbaze iji belata agba nke ink e ji mmiri mee, a pụkwara iji ya dị ka ihe na-eme ka ọ na-enwu gbaa iji melite enwu nke ink e ji mmiri mee. Na mgbakwunye, ekwesịrị itinye ụfọdụ wax na ink e ji mmiri mee iji mee ka ọ ghara iyi.
A pụrụ ịgwakọta ink e ji mmiri mee na mmiri tupu a kpọọ ya nkụ. Ozugbo ink ahụ kpọrọ nkụ, ọ gaghịzi agbaze na mmiri na ink.
