Inki Whakarite Etita Hihiri i te Pakihi mo Nga Rawhiti Matataki

Te whakapapa tohu me te tuhinga, he wāhi iti o te whakapapa flexographic, kua puta hei whiriwhiri e mōhio ana mō te whakauru i ngā tohu mō ētahi atu rorohiko. Ko tana hiranga mai i te mea ka taea e ia te whakarite i ngā taupokipoki pai rawa, te whai oranga moni, me te whakarite ki ngā huringa katoa o ngā tūtohu. Ki te matua o te whakapapa tohu flexo, ko te whakamahi i ngā papa tuhinga nui. E ai ki te tikanga, e hanga ana ngā papa i te karepe rānei, i ngā momo photopolymer, ka taea e rātau te whakariterite ki te hoahoa ā-waho o te tohu. Ko te kawa o te hanga papa kei reira, ko te whakahokia i tētahi whakaahua matihiko ki runga i te momo papa, ki te āniwaniwa tonu (mō ngā papa photopolymer) rānei, ki te hanga whakairo noa (mō ngā papa karepe). Ko ngā wāhi pānga i runga i te papa, ko te whakaahua e tuku nei, ko ngā wāhi tataki haere, ko te wāhi kore ink. Ko te whakamomori i te ink he mea nui i roto i te whakapapa tohu flexo. Kei te wāhi e rua whai ake nei ngā momo ink flexographic, inaianei, ko ngā ink i te mamae, i te wai, me ngā ink UV - curable. Ko ngā ink i te mamae e mōhio ana mō ōna hokinga herehere me te pai o te whakapae ki ngā papa kore poroporohe pērā i ngā papa karatia. Ko ngā ink i te wai, nā reira, he pai tonu mō te ao taiao, me utu iho hei whakarite mō ngā mahi e hiahiatia ana te waipiro iti me te itinga i te VOC (VOC), pērā i ngā tohu pākete kai. Ko ngā ink UV - curable e tino pai ana te hokinga me te tūmanako pai, e pai ana mō ngā tohu e hiahiatia ana te whakaritorito rerekē rānei, me te whakaritorito o te ao marangai. Ko te kawa o te whakapapa anō he whakamahi i te rīpora anilox hei whakawhiti i te ink ki te papa tuhinga. Ko ngā karaunga o te rīpora anilox ka noho ink, ka whakawhiti i aua ki ngā wāhi pānga i runga i te papa. Ka huri te papa, ka tae ki te papa tohu, ka tukuna te ink ki te whenua, ka hanga te whakaahua i tuku. Ka taea e te whakapapa tohu flexo te whakarite i te nuinga o ngā papa tohu, mai i te kākahu me te kāri ki ngā momo papa whakahirahira, pērā i ngā papa foil me ngā papa film sintetik. He tautoko hoki i ēnei kēmu tuhinga, pērā i ngā tae spot, ngā kauwhata, me ngā halftones, hei hanga i ngā tohu pai mata. Nā te mea hoki, ka taea te hanga i ngā mahi tuhinga muri, pērā i te tahua, te lamination, me te varnishing, hei whakapai i te whanonga me te whakaaturanga o ngā tohu, hei whakarite mō ngā mahi tūpito, pērā i te whakamārama take, te tohu paeroa, rānei, te kawe ātaata.
