Ekuphrinteni kokupakisha, umbala wangemuva uvame ukuphrintwa kuqala ukuze kuthuthukiswe izinga eliphezulu lomhlobiso wephethini futhi uphishekele inani eliphakeme elingeziwe lomkhiqizo.Ekusebenzeni okungokoqobo, kutholwe ukuthi lolu chungechunge lokunyathelisa luthambekele ekukhanyeni kwe-inki.Siyini isizathu salokhu?
I-1, Ukuze kuzuzwe ingemuva elikhanyayo nelikhanyayo, ungqimba lukayinki luvame ukuphrintwa oluwugqinsi noma luphinde luphrintwe kanye noma ngomfutho wokuphrinta okhuphukile, futhi uwoyela owomile owengeziwe wengezwa ngesikhathi sokuphrinta.Nakuba ungqimba lukayinki lumboza ngokuphelele isithwali sokuphrinta, ukomiswa okusheshayo kubangela ungqimba lwefilimu lukayinki olubushelelezi kakhulu ebusweni bukayinki wokunyathelisa ngemva kokwakhiwa kwefilimu, okwenza kube nzima ukuphrinta ngokweqile kahle, njengengilazi.Lokhu kwenza uyinki uphrintwe ngokungalingani noma kungenzeki nhlobo ukuphrinta.Uyinki kawoyela ophrintwe kukhava (isitaki) uveza ubuhlalu obufana noma amaphethini wokuphrinta anombala obuthaka kumbala oyisisekelo, futhi uxhumo lweyinki lubuthaka, okunye okungasulwa.Imboni yokunyathelisa ibhekisela kuyo njenge-crystallization yefilimu kayinki, i-vitrification, noma i-mirrorization.
Ukuze kuthuthukiswe ukucaca kwezithombe nemiphetho yombhalo, abakhiqizi abaningi bangeze uwoyela we-silicone ezinhlelweni zikayinki eminyakeni yamuva.Kodwa-ke, uwoyela we-silicone ngokweqile uvame ukubangela ukuncipha okuqondile kwefilimu kayinki.
Njengamanje kunemibono eminingana ehlukene ngezizathu zokucwebezeliswa kwamafilimu ayinki.Ngokusho kwe-crystallization theory, i-crystallization iyinqubo yokwenza amakristalu avela oketshezini (uketshezi noma ukuncibilika) noma isimo segesi.Into okuncibilika kwayo kwehla ngokuphawulekayo ngezinga lokushisa elinciphayo, futhi isixazululo sayo singafinyelela ekugcwalisweni futhi sicwebezele ngokupholisa;Into okuncibilika kwayo kwehla kancane ngezinga lokushisa elinciphayo, icwebezela lapho ezinye izinyibilikisi zihwamuka bese ziphola.Abanye abantu bakholelwa ukuthi icrystallization yokupakishwa kwezithombe zokuphrinta nemibhalo (i-ink film layer) ibizwa ngokuthi i-recrystallization... Uhlelo lwefilimu ye-inki yokuphrinta lwakhiwa ukuhwamuka kwe-solvent (evaporation) bese kuba ukupholisa, okwaziwa nangokuthi i-recrystallization.
2, Abanye abantu bakholelwa ukuthi i-crystallization (crystallization) ye-inki yokunyathelisa yokupakisha ibangelwa ikakhulukazi ukucwebezela kwezingulube ohlelweni lweyinki.
Siyazi ukuthi uma amakristalu e-pigment eyi-anisotropic, isimo sawo sekristalu siyinaliti noma induku.Lapho wenza ifilimu ye-inki, isiqondiso sobude sihlelwa kalula ngokuhambisana nokugeleza kwe-resin (impahla yokuxhuma) ohlelweni, okuholela ekunciphiseni okuphawulekayo;Kodwa-ke, akukho ukuhlelwa kokuqondisa ngesikhathi sokucwebezeliswa kwe-spherical, okuholela ekuncipheni okuncane.Imibala ye-Inorganic kumasistimu kayinki wokuphrinta ngokuvamile anamakristalu ayindilinga, afana noyinki wokuphrinta osuselwe ku-cadmium, ophinde abe nokuncipha okuncane (crystallization).
Ubukhulu bezinhlayiyana buphinde buthinte izinga lokuncipha kokubumba kanye nesilinganiso sokuncipha kokubumba.Lapho izinhlayiya ze-pigment zizinkulu noma zizincane ngezinga elithile, izinga lokuncibilika lokubumba kanye nesilinganiso sokuncipha lincane kakhulu.Ngakolunye uhlangothi, ama-resin anamakristalu amakhulu kanye nokuma okuyisiyingi abonisa ukushwabana okuncane okubumbayo, kuyilapho ama-resin anamakristalu amakhulu namajamo angewona ayisiyingi abonisa ukushwabana okukhulu kokubumba.
Ngamafuphi, kungakhathaliseki ukuthi ukuxuba okukhiphayo kombala wombala noma ukuxuba okungeziwe kokukhanya kombala, ukusetshenziswa okulungile kwama-pigments akuhlobene kuphela nesakhiwo samakhemikhali, kodwa futhi kuncike kakhulu ezintweni zabo ezibonakalayo, njengokusabalalisa usayizi wezinhlayiyana zekristalu, izenzakalo ze-condensation, izixazululo eziqinile, nezinye izici ezinomthelela;Kufanele futhi senze ukuhlola okulungile kwezinzuzo kanye nokungalungi kwakho kokubili kombala we-inorganic kanye ne-organic, ukuze kuhlalisane, futhi lokhu kubambe isikhundla esiyinhloko.
Lapho ukhetha inki yokunyathelisa yokupakisha (i-pigment), kuyadingeka futhi ukucabangela amandla ayo ombala (ukusabalalisa kahle, amandla ombala aphezulu, kodwa kunenani elilinganiselwe elingaphezu kwalokho amandla ombala azokwehla) Amandla okuvala (izici zokumunca. ye-pigment ngokwayo, umehluko wenkomba ye-refractive phakathi kwe-pigment kanye ne-resin binder edingekayo ukuze kufakwe umbala, ubukhulu bezinhlayiya ze-pigment, uhlobo lwekristalu lwe-pigment, kanye ne-symmetry yesakhiwo samangqamuzana e-pigment ephakeme kunaleyo ye-symmetrical. ifomu eliphansi lekristalu).
Amandla okumboza wefomu le-crystalline likhulu kunelomumo wenduku, futhi amandla okumboza ama-pigments ane-crystallinity ephezulu makhulu kunama-pigments ane-crystallinity ephansi.Ngakho-ke, lapho amandla okusibekela efilimu kayinki yokupakisha ephrinta, maningi amathuba okuthi kube nokuhluleka kwengilazi.Ukumelana nokushisa, ukumelana nokufuduka, ukumelana nesimo sezulu, ukumelana nokuncibilika, nokusebenzelana nama-polymers (ama-resins kumasistimu kayinki kawoyela) noma izithasiselo azikwazi ukubukelwa phansi.
3, Abanye o-opharetha bakholelwa ukuthi ukukhetha okungafanele nakho kungabangela ukwehluleka kwe-crystallization.Kungenxa yokuthi uyinki eyisisekelo yoma kakhulu (kakhulu), okuholela ekwehleni kwamandla angaphandle.Njengamanje, uma isikhathi sokugcina ngemuva kokuphrinta kombala owodwa siside kakhulu, izinga lokushisa le-workshop liphezulu kakhulu, noma kukhona ama-desiccants kayinki amaningi wokuphrinta, ikakhulukazi ama-cobalt desiccants, uma izindlela zokumisa ngokushesha nezinamandla, njengokumisa, zisetshenziswa, i-crystallization phenomenon. kuzokwenzeka.
