Ngā Pūrongo - Ka puta te paru i te maroke o te waituhi puhoi i roto i ngā mīhini tā flexo tae whā/ono, pepa tere-tere aunoa. Me pēhea te whakapai ake?

I roto i te tukanga mīhini flexographic, he wero tonu mō ngā kamupene tā te maroke puhoi o te waituhi e arahi ana ki te paru. Ehara i te mea ka pā tēnei ki te kounga tā me te whakanui ake i te para engari ka whakaitihia hoki te pai o te whakaputa, ā, ka whakaroa pea i ngā wā tuku. Me pēhea te whakatau tika i tēnei take? Ka whakaratohia e mātou he otinga whānui e kapi ana i te kōwhiringa waituhi, te arotau tukanga, te whakapai ake i ngā taputapu, me te whakahaere taiao hei āwhina i a koe ki te whakakore i te paru me te whakatutuki i te whakaputa tā pumau, tino pai.

● Kōwhiringa Waituhi me te Arotautanga Tātai – Te Whakatau i ngā Take Maroke i te Pūtake

Mō ngā mīhini tā flexo, he mea nui te whiriwhiri me te hanga waituhi hei whakatika i ngā raruraru maroke. Ka tūtohu mātou i ngā waituhi tere-maroke, pērā i ngā waituhi whakarewa me ngā hanganga tere-whakarerekē, ngā waituhi wai rānei me ngā whakaterenga whakamaroke. Mō te tere whakamaroke mōrahi, ko ngā waituhi UV me ngā pūnaha whakamaroke ultraviolet te kōwhiringa pai rawa atu. Mā te whakarerekē i ngā ōwehenga whakarewa—pērā i te whakanui ake i te ihirangi ethanol, ethyl acetate rānei—ka taea te whakapai ake i te mahi whakamaroke me te pupuri tonu i te pumau o te waituhi. Hei tāpiri, mā te whiriwhiri i ngā tāpiringa whakamaroke tika (hei tauira, ngā whakamaroke cobalt/manganese mō ngā waituhi whakamaroke waikura, ngā wero motuhake rānei mō ngā papa mimiti) ka whakarite i ngā hua tino pai.

● Ngā Whakapai Ake i te Pūnaha Whakamaroke – Te Whakapai Ake i te Whai Huatanga

Ka pā tika te mahi a ngā pūnaha whakamaroke i roto i te mīhini tā flexo ki ngā hua. Tirohia auau ngā whakamaroke kia tika ai ngā tautuhinga pāmahana (50–80°C mō ngā waituhi whakarewa, he iti ake te āhua mō ngā waituhi wai) me te rere o te hau kāore e āraia. Mō ngā tono uaua, whakapai ake ki te whakamaroke infrared mō te whai huatanga ā-rohe, ki te whakamaroke UV rānei mō te whakamaroke tere. He tino whai hua ngā waeine whakamaroke hau makariri mō ngā kiriata kore-mimiti hei ārai i te makuku anō o te waituhi.

● Te Arotau i te Tukanga Tā – Te Whakatikatika i ngā Tawhā Whakaputa

I roto i ngā mīhini tā flexographic, ko te arotau i ngā tawhā whakaputa ka tino whakapai ake i te pai o te whakamaroke. He mea nui te whakahaere i te tere tā—ko te tere nui ka ārai i te whakamaroke tika i mua i te teihana tā e whai ake nei. Whakatikatikahia te tere i runga i ngā āhuatanga waituhi me te kaha whakamaroke. Ko te whakahaere i te matotoru o te kiriata waituhi mā te whiriwhiri tika i te roera anilox me te rahinga waituhi ka ārai i te nui o te kohikohinga. Mō te tānga maha-tae, ko te whakanui ake i te mokowā teihana, te tāpiri rānei i ngā whakamaroke i waenga i ngā teihana ka roa ake te wā whakamaroke.

● Te Taiao me te Urutaunga Papatūānuku – Ngā Take o Waho Nui

He nui te pānga o ngā āhuatanga taiao i roto i ngā mahi tā flexo ki te whakamaroke. Kia mau tonu te pāmahana o te papa o te toa ki te 20–25°C me te haumākū ki te 50–60%. Whakamahia ngā whakamaroke haumākū i ngā wā haukū. Ko te maimoatanga o mua i te papa (hei tauira, te maimoatanga korona mō ngā kiriata PE/PET) ka whakarei ake i te piri o te waituhi me te whakaiti i ngā hapa whakamaroke.

Whakahaere Makuku

Hei whakamutunga, mā te mahere tiaki pakari ka pumau te mahi mō te wā roa. Horoia ngā pūwero whakamaroke me ngā wāhanga whakamahana i ia wā, tirohia te pakaru o te roera anilox, ā, whakamahia ngā taputapu whakamātautau maroke hei aroturuki i te kounga o te tānga—he mahi matua hei ārai i ngā take e pā ana ki te whakamaroke.
