He aha ngā tinta intaglio e noho ana ki ngā pouaka pakuake?

He aha ngā take e poro ai ngā Inika Intaglio Aqueous Tikanga ki te Papakātanga—Ngā Matua Take o te Here me te Wettability

Te Kore ōrite o te Kaha o te Mata: PET, PP, BOPP vs ngā Tono Inika Huinga Wai

Ko ngā rangi energi mata o ngā matēriau whakaputonga pāpataurangi noa pērā i te PET (Polyethylene Terephthalate), PP (Polypropylene), me te BOPP (Biaxially Oriented Polypropylene) e heke iho ai i te 35 mN/m, e noho ana tino i raro i te tohu 40 mN/m e hiahiatia ana kia reriua ai ngā tinta ā-whānui ki ngā mata me te pakari. Ko te wai anō ko te ahunga ahurea mata tino teitei e toru tekau mā rua mN/m, nō reira inā hui ana ki ēnei pāpataurangi energi iti, ka kitea e mātou te tākarotanga takitahi atu i te hononga. Ko ēnei mata pāpataurangi makauri he wehe tonu i te pepa, i te karatapu hoki nā te mea kāore he poro iti, he wāhi parurenga rānei ka pakari ai te tinta. Nō reira ko ngā tinta ā-wai noa ka rere noa iho i te whānuitanga o te matēriau. Mērā kāore he pakari tika, kāore ngā whakaahua takotoria e maroke ana i ngā tikanga whakamahinga, whakawhitinga hokohoko rānei.

Ngā Aronga Herenga: Pīngao, Kāore i Pakari, me te Tuku Kiri Kāore i Tino

Ko te wehenga energi mata e arataki tūmatanui ana i ngā hapa whakahaere e toru:

• Whakaputangia : Ko te tinta ka reriua ki ngā karu kiko, kaua ko ngā takotoranga ōrite, ā, ka hua he takotoranga kore āhuatanga.
• Whakaweretia : Ka tōtō anuanu te tinta i te parurenga, ka whakarewa i te mata takotoria, ka pāngia te opaqueness me te aha o te here.
• Kāore i te tuku tino : Kāore ngā wā kōpae gravure e tuku tinta taurite ai i raro i te toto, ā, ka hua he āhua (ghosting) me te ngaro i ngā taipitopito māmā.
  Kotahi nei ngā ngoikera e piki ake ana i te 25% te tau whakakore mō ngā tauira hoki me te wā kāore i whakaritea—he nuinga rawa atu i ngā rārangi pakete kai tere kei reira hoki e poke ana ngā kiri tinta kore tata, ka pā ki te kounga herehere me te roa o te kai.

Ngā Whanaketanga Harwarenga e Wātea Ana i te Tinta Intaglio Aqueous mō te Pārihi

Acrylic, Polyurethane, me ngā Huinga Kōaro: Te Taurite i waenganui i te Pakari, te Maroke, me te Manawa

Ko ngā tioata intaglio auau o te rā nei mō ngā matapae pāroparo he herekenga hou pea i ngā papahiko paraihe e whakahaere ana i te āhua pakari, te kaha maroke, me te kounga roa. Ko ngā paraire akarika anake e mahi pai ana mō te hononga ki ngā mata heru pērā i ngā kiri BOPP me ngā kiri PET nā rātou koia ngā rōpū mata motuhake kei roto, ā, ānō rātou hoki i ngā kiri e tino pai ana mō te kikokiko. Ā, ko ngā papahiko puarauni e hoatu ana e rātou te kaha taraiwa me te tiaki i ngā taupā atamira, he mea nui tēnei ina pēra ngā pouaka ka harapaina, ka whanua i te wā o te hanganga, i te kawe rānei. Ina honoa e ngā kaihanga ngā akariki me ngā puarauni ki ngā tauira takotoranga, ka riro i a rātou ngā putanga pai rawa o ia tahi mō ngā tuhinga e tino mau ana i ngā āhuatanga katoa o te ao tinana. Ka taea e ēnei papahiko inu hōu te tuku ake i te 90 miriona tau eke ake rānei o te tioata ki ngā pāroparo i te wehe korona (te piko noa o te ahunga mata 40 mN/m), ā, ānō rātou tonu i ngā ture FDA 21 CFR me ngā tikanga EU 10/2011 mō te haumātaotao o te kai āwhina, ānoa rānei i te itinga VOC me te hiahia ki te kino i ngā piripiri mai i te whakamahinga noa.

Te Whakaritenga o te Mata: Te Tīmatanga o te Tikanga me te Whakaurunga i te Pēhi

Te Whakanuia Korena: Te Hinga Pakari o ngā Rawa Dyne >40 mN/m mō te Tuku Tinta Kaupapa

Ko te mātai korona te ara matua ina tūhono ana i te PET, PP, me te BOPP mō ngā whakamahinga tapa kōhatu mā te wai. Kei konei te pānga o te papanga ki te hinu ka hangaia e te hinu i runga i te papanga, ā, ko ngā rōpū herehere takotoranga nei e hiahiatia ana. Ka piki ake ngā rahi o te arataki ki runga ake i te 40 mN/m, he rāwekenga nui rawa kia pai ai te karapoti karawhiti me te tuku kaua ko ngā raruraru. Ko te nuinga o ngā mātai ka pāngia te arataki ki waenganui i te 15 ki te 25 mN/m ake, engari he take kei reira. Kāore ngā pānga e roa ana. Mēnā ka waiho noa, ka tūpato kaua ko ngā pene ka hoki anō ki raro i te 38 mN/m, ka arisai ngā raruraru pērā i te karawhiti karaka, me te iti noa te here. Nō reira he maha ngā mahi e whakahaere ana i ngā mātai arataki mō te wā kotahi me ngā whakarerekenga pūmanawa aunoa. Ka pupuri tēnei tautāwhai i te rahi o te mātai pana i ngā wā katoa o te huringa mahi. Kua ripoata ngā kamupene pakete kua kitea e 70% te itinga o ngā hararu tapa i te wā ka whakauru tēnei tautāwhai, ahakoa ka rerekē ngā putanga ki te kounga o ngā taputapu me te pūkenga o te kaimahi.

Whakamaroke, Whakapiri, me te Titiro Ki te Tension i runga i ngā Patu Tere-Whakauru

He nui te takotoranga o te tautohe i muri i te whakawhitinga inu mō ngā tūtohi pāpāho mō ngā hua paraiharai e mahi ana ki ngā inu e pā ana ki te wai. Kāore pea ngā punaha rāwekenga mātātoko maha e rere ana i waenganui i te 60 ki te 80 nekeneke Celsius e āki ai te wai tūmataiti engari kia kaua ai te āhuatanga kino. I te wā kotahi, kāti ngā here herehere e pupuri ai te pono i te wā o te tautohe, e pupuri ana i te here here i roto i te haurua Neutone ia mitamita tapawhā. Ko te tautau atamira kei te tīmatanga i ngā rōparo nip e uru ana me ngā arataki iti epeketia e pakari ana i ngā raruraru herehere. Ka āwhina tēnei ki te pupuri i te pono o te rerekētanga tika, ā, ahakoa e rere ana i ngā tere kaha ake i te 200 mita ia miniti. Mō ngā wā rāwekenga, ko ta mātou whāinga he tata ki te tahi hēkona, heoi anō, e āki ai te hononga kotahi o ngā pūnaha kaiārahi acrylic me polyurethane. Ko ngā tikanga e puta mai ana ka taea ai te toronga ake i te 500 whakamātau toronga ké ASTK, i te wā e pupuri ai i ngā hua e hoki ano ai me te whakawhanaketanga ki ngā aha ake i muri i te whanaketanga.

Whai mātauranga, Haumaru, me te Ū ki ngā Pakihi Mātai Kai mō ngā Pakarau Pāpaku Kua Tāpirihia ki te Kai

Whakamātautau Ake me te Whakaaetanga Rāwekenga (EU 10/2011, FDA 21 CFR) mō ngā Tinta Inga Waima

Ko te waihanga inu ake taiapa e taea ai te whakapā atu ki ngā paraihe kai he mea matatū pea i ngā tikanga o EU Regulation (EU) No 10/2011 me ngā paerewa FDA 21 CFR Part 175-177. Ko ēnei whakamātautau tango he mātai i te nui o ngā mea rerekee e rere ana ki ngā tauira kai i ngā tikanga rerekē o te kiko, roa, me te pānga. He mea hoki ngā matapae e whai ana, nā te kore porowhita o PET, PP, BOPP, kaore i te u ana, arā, ko te rereketanga anake kei te takotoranga mata, ka nui ake te nuinga o te hanganga inu me te pā ki te paparanga. Kua whakapakari ake ngā rōpū whakahaere i ngā here i ēnei wā. Hei tauira, e hiahia ana te FDA kia iti ake i te 1 pera i te piriona ngā taumata kitea mō ngā metara taumaha me ngā mea kāore i tūtohu (NIAS). I te wā e totohe ana ngā arataki o Eropi kia tārohatia tonu ia waahanga, tae atu ki ngā taputapu me ngā kaitōmuri. Kāore i te take anake te āhuatanga kimikimi anō hoki. Me tiakina e ngā kaiwhakawhanaketanga kia mau tonu ēnei inu i muri i te whakamomori, i te whakarahi i te mīkawēvi, i te noho i ngā taiao makariri rānei. Ka tiaki i te haumanu o te tangata e kai nei i ngā hua pakipaki ana ki ēnei matapae, ā, āwhina hoki i ngā whakangungu whakauru anuanei e mahi ana i roto i ngā punaha whakahaere pāmu kua wātea.
