Te Whakamātautau Tihārahi Matua: He aha ai tāu hāngā i tēnei

Te Whakamāhinga Tāwhai o ngā Whakaprinti Matua Kāore i te Whakamāhinga o te Kōpae Tāwhai Tāwhai

Te whakamāhinga o te toner i raro i te hīkoi, i te hūtānga, me ngā mahi — he aha ngā whakaprinti matua e whakamāhinga ana i tēnei wā

Ko ngā whakamātautau matua e whai ana i ngā wāhanga toner e whakauru ana ki te papamahi i te hōhi me te pākihi. I raro i ngā inki o te whakamātautau āwhina, kāore ngā inki e whai ana i ngā kōpū o te pepa, engari ko ngā wāhanga toner e noho ana i te whāriki hei rēsini thermoplastic—ka whakamārama i tēnei te mātātūtanga. Inā heke mai i te hau hāngai (i te 60% RH), ka whai ngā wāhanga toner i te wai, ka pānui, ka whakamāmā i ngā pākoki iti, ā, ka rere. Ko ngā whakamāmā hōhi—e rite ana ki ngā whakamāmā i te tāruatanga, i ngā wāhanga o ngā waka, i ngā tohu ā-wāhi—ka whakamāmā i ngā wāhanga toner, ka whakarere i ngā whakamātautau iti. Ā, ko ngā whakamātautau ā-tāngata anō hoki e tāwhai ana i ngā hinu o te kaki, ka whakamāmā i te hononga i waenganui i ngā wāhanga toner me te papamahi. Ko ēnei ngā whakamāmā e noho ana i ngā wiki: ka māmā te whakamātautau o te tae, ka kōkō ngā tapa, ā, ka māmā te tūāpapa o te whāriki. Ko ngā kōpū whakamātautau o te hōhi digital he whakamātautau hei whakamāmā i ngā wāhanga toner i roto i tēnei kōpū rēsini tūpā, hei whakamāmā i te uru mai o te wai, hei whakamāmā i te whakamāmā hōhi, ā, hei whakamāmā i te whakamātautau o te āhua o te whāriki.

Ngā whakamātautau a-tāone: Ko ngā whakamātautau digital kāore i te whakamāmā, ko te 68% o ngā whakamātautau e kitea ana i te whakamāmā i roto i ngā 90 ra (SGIA 2023)

I tēnei tau 2023, i whakamātau te Specialty Graphic Imaging Association (SGIA) ā, kua kitea ko ngā pōster rorohiko kāore i te whakamātai i te whakamātai, kua hinga tonu i tēnei wā—ko ngā whakamāhinga o te tae, te whakamāhinga o ngā tapa, me ngā whakamāhinga o te whāriki—i roto i ngā 90 ra tuatahi o te whakamāhinga i roto i te whare. I ngā whakamāhinga i waho, kua hinga ngā pōster i te 89% i tēnei wā anō, nā te whakamāhinga o te UV, ngā rere o te uku, me ngā whakamāhinga o te whāriki i te wā o te whakamātai me te whakamāhinga. I te rere, kāore ngā pōster i te whakamātai i te whakamātai o te rorohiko i te whakamātai o te hōu i te hōu i tēnei wā. Ko tēnei he whakamātautau i tēnei whākanga: ko ngā whakamāhinga rorohiko kāore i te whakamātai he mea pūmau. Ko ngā whakamāhinga e hiahiatia ana te pūmau i te wā i muri i ngā marama e toru, e hiahiatia ana te whakamātai—ko te utu o te whakamātai anō, o te whakamātai anō, me te whakamāhinga o te ingoa, he nui ake i te utu iti o te whakamātai.

Me pēhea te whakamātai o te whakamātai o te hōu o te rorohiko i tēnei raruraru: te kimihanga, te whakamātātutanga, me te whakamāhinga

Te polyester vs. te polypropylene: te whakamāhinga o te whakaahua, te whakamātai o te whakamāhinga o te hōu, me te whakamātai o te toner

Ko te kōpae taketake he mea matua e whāia ana i te whai hua. Ko te polyester he pai ake i te whakaahua i ngā whakaahua—ko tana rere o te āhua e whakamātau ana i te pūmau o ngā tae me te whakaatu i ngā kupu, ahakoa ngā whakaahua i raro i ngā hauā o te mātātoko—ā, e whakamātau ana hoki i te pūmau o ngā āhua i te wā o te whakamātai, e iti ake ana i te 0.5% te whakamātai i ngā hāngā mātātoko. Ko te polypropylene, i te whakamātautau, he nui ake te whakamātai o te hōhi, ā, he whāia pea te whakamātai i ngā whakaahua o te mātātoko mātātoko. Mō ngā whakaahua matihiko, he tino whakamārama te polyester: ko tana pākaha o te āhua e whakamātau ana i ngā rārangi toner, e whakakore ana i ngā whakamārama o te whakamātai, o te whakamātai, o te whakamātai rānei.

Te pūnaha o te whakamātai o te hōhi: ngā whakamārama e whai ana i te whakamātai i raro i te hōhi, kāore he whakamātai, kāore he whakamātai o ngā rārangi toner

Ko te whakamātau i te whakamātua i te hāngai i te whakamātua i te hāngai i te kore pākūnga. Ko ngā kōpae whakamātua ā-ihirangi e whakamāhi ana i ngā hāngai tāwhai-hōu iti—i tēnei wā he rereke i waenganui i te 180–210°F—hei rereke iti i te wā o te whakamātua o ngā toner nui (≈250°F). Nā reira, kāore he whakamātua anō, he whakamātua, he ngaro o ngā whakamārama i te wā o te whakamātua. Ko te hāngai o te hāngai e whakamāhi ana i ngā pōlymer whakamātua e hanga ana i ngā hāngai o te mōhio i te rereke o ngā pārāwaha toner, e whakamātua ana i a rātou i te wā tonu, i te whakamātua i te whakamātua o ngā whakamārama me ngā rārangi iti.

Ngā Huinga Whakamātautau o te Whakamātautau: UV, Wai, me te Whakamātautau o te Tāpoi

≥99% o ngā UVA/UVB e rere ana — Te whakamātua i te tika o te tae me te whakamātua i te whero i ngā tohu me ngā whakamātautau o te hokohoko

Ko te kiri whakamātua mātātoko matua hāngai ki te tāwhai i te hōhi, e rere ana i te 99% o ngā whakamātua UVA me ngā whakamātua UVB—ka whakamātua te whakamātua o ngā pūrongo ā-hāngai e hāngai ana ki te whakamātua o ngā tāwhai me ngā whakamātua o ngā wāhanga. Ko ngā tāwhai kāore i te whakamātua i ngā wāhi hokohoko, i ngā whakamātua wāhanga, he rite te whakamātua o ngā whakamātua o ngā tāwhai me ngā whakamātua o ngā wāhanga i te toru marama. I te whakamātua o ngā whakamātua UV katoa, ko te tāwhai o ngā tāwhai e tāwhai ana, ā, ko te whakamātua o ngā tāwhai e tāwhai ana—e tautoko ana i te tāwhai o te toa me te whakamātua o ngā utu whakamātua.

Te kaha o te whakamātua ≥120 N/cm me te pākaha o te pene ≥3H — e whakamātua ana i ngā whakamātua o ngā whakamātua, o ngā whakamātua, me ngā whakamātua o te whakamātua

Ehara te roa o te ora i te mea tika, engari ko te kaha ki te noho i raro i ngā āhuatanga tūturu. He kaha waikore o ≥120 N/cm e whakarite ana kia kore e pakaru te laminate, te hiki i te taha, me te kaha i te wa e whakauru ana me te whakahaere. He tohu pakeke pene ≥3H e whakapūtā ana i te ātete ki te kōkō o ia rāmai i ngā papanga horoi me ngā whao, ki te whakakao i te kaata me te kōkō haere. I te taha kotahi, ka ārai ēnei tātai i te delamination, te kōpeke, me te kākahu o te mata, e whakawhānui ana i te ora mahi puta noa i ngā tono hokohoko, hokohoko, me waho.

Te Whakapaipai i te Tikanga Whakapaipai Whakaahua Whakaahua mo nga Hua Koreutu

Te whakawātea i te pāmahana, te wā noho, me ngā kawa whakawātea hei ārai i te hiriwa me te delamination

Ko ngā huinga kore heke i te whakamātautau i ngā rārangi e toru e whai pānga ki tēnei. Tuatahi, me whakamātautau te wāhi kia rite ki te roa o te whakamātautau o te kōpae kia tūhono—i te nuinga o te wā ko te 90°C ki te 130°C—kia kaha ake te whakamātautau i te kōpae, ā, kia kore ai te whakamātautau i te toner (e whakaatu ana i te kōpae kākāriki: ngā pūpū hau e noho mai ana). Tuarua, me whakamātautau te wā o te whakamātautau kia tūhono te whakamātautau katoa o te kōpae ki te whakamātautau o te hīkawea; mēnā he iti te wā, ka heke te whakamātautau, mēnā he roa te wā, ka raru te toner i te whakamātautau anō. Tuatoru, kāore he whakaaetanga i te whakamātautau: me noho ngā pepa i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whakamātautau i te wāhi o te whak......
