Isethulo: Icwebezela lento ephrintiwe isho izinga lapho ikhono lokubonisa lendawo ephrintiwe kuya ekukhanyeni kwesigameko liseduze nekhono eligcwele lokubonisa elikhethekile.Ukucwebezela kwezinto eziphrintiwe kunqunywa ikakhulukazi izici ezifana nephepha, uyinki, ukucindezela kokuphrinta kanye nokucubungula kwangemuva komshini.Lesi sihloko sichaza umthelela kayinki ekuphrinteni isicwebezelisi, okuqukethwe kwereferensi yabangane:
 
Isici sikayinki esithinta ukucwebezela kokuphrinta
20
Ikakhulukazi ubushelelezi befilimu yeyinki, enqunywa ubunjalo nenani lempahla yokuxhuma.Uyinki kufanele aqukathe umbala ocolekile ohlakazeke ngokulinganayo, futhi ube ne-viscosity eyanele kanye nesivinini sokumisa ngokushesha ukuze kugwenywe ukungena ngokweqile kwezibophelelo ezimbotsheni zephepha.Ngaphezu kwalokho, uyinki kufanele futhi ube fluidity omuhle, ukuze ukwakheka bushelelezi uyinki ifilimu ngemva kokunyathelisa.
 
01 Ubugqinsi befilimu kayinki
Ku-binder ye-inki yokumunca esiphezulu sephepha, i-binder esele isagcinwe kufilimu kayinki, ingathuthukisa ngempumelelo ukucwebezela kwendaba ephrintiwe.Lapho ifilimu ye-inki ishuba, kuba yilapho kuba khona okusalelayo okuhlanganisayo, kuba nomthelela omkhulu ekuthuthukiseni ukucwebezela kwezinto eziphrintiwe.
 
Ukucwebezela kuyanda ngokuqina kwefilimu kayinki, nakuba uyinki ufana, kodwa isicwebezelisi sokuphrinta esakhiwe izinguquko zephepha ezihlukene ngobukhulu befilimu kayinki yehlukile.Uma ifilimu ye-inki imncane, ukucwebezela kwephepha eliphrintiwe kuncipha ngokukhula kogqinsi lwefilimu kayinki, ngenxa yokuthi ifilimu kayinki ihlanganisa isicwebezelisi esiphakeme sangempela sephepha ngokwalo, futhi ukucwebezela kwefilimu uqobo kuncipha ekumunceni iphepha;Ngokukhula kancane kancane kogqinsi lwefilimu kayinki, ukumuncwa kwesibophezelo kuyagcwala, futhi nokugcinwa okungaphezulu kwesibophezelo kuyenyuka, futhi isicwebezelisi siyathuthuka.
 
Ukucwebezela kokuphrinta kwebhodi lephepha elinamekwe kukhuphuka ngokushesha ngokwanda kogqinsi lwefilimu kayinki.Ngemuva kokuthi ukushuba kwefilimu kayinki kukhuphuke kube ngu-3.8μm, isicwebezelisi ngeke sisakhula ngokukhula kogqinsi lwefilimu kayinki.
 
02 Uketshezi lukayinki
21
I-fluidity kayinki inkulu kakhulu, ukwanda kwamachashazi, ukunwetshwa kosayizi wokuphrinta, ukuncipha kongqimba lukayinki, isicwebezelisi sokuphrinta asilungile;I-fluidity ye-inki incane kakhulu, isicwebezelisi esiphakeme, uyinki akulula ukuyidlulisela, ayihambisani nokuphrinta.Ngakho-ke, ukuze uthole isicwebezelisi kangcono, kufanele alawule fluidity uyinki, hhayi enkulu kakhulu angeke ibe mncane kakhulu.
 
03 Ukulinganisa kukayinki
 
Enqubweni yokunyathelisa, ukushelela kweyinki kuhle, ukucwebezela kuhle;Ukulinganisa okungalungile, ukudweba okulula, ukucwebezela okungalungile.
 
 
04 Okuqukethwe Kwe-Ink Pigment
 
Okuqukethwe kwe-ink pigment kuphezulu, kufilimu kayinki kungakha inani elikhulu lama-capillaries amancane.Ikhono lalezi zinombolo ezinkulu zama-capillary amancane okugcina i-binder likhulu kakhulu kunekhono legebe le-fiber surface yephepha ukuze limunce isibophezelo.Ngakho-ke, uma kuqhathaniswa noyinki onombala ophansi, uyinki onombala ophezulu ungenza ifilimu kayinki igcine izibophezelo ezengeziwe.Ukucwebezela kwamaphrinti asebenzisa i-inks yokuqukethwe kwe-pigment ephezulu kuphakeme kunaleyo yamaphrinti anokuqukethwe kombala ophansi.Ngakho-ke, izinhlayiya ze-ink pigment ezakhiwe phakathi kwesakhiwo senethiwekhi ye-capillary yisici esiyinhloko esithinta ukucwebezela kwezinto eziphrintiwe.
22
Ekuphrinteni kwangempela, ukusetshenziswa kwendlela kawoyela okhanyayo ukwandisa ukucwebezela kokuphrinta, le ndlela ihluke ngokuphelele endleleni yokwandisa okuqukethwe kwe-pigment kweyinki.Lezi zindlela ezimbili zokwandisa ukucwebezela kwezinto eziphrintiwe kuhlelo lokusebenza, ngokusho kokwakheka kwe-inki nokuphrinta ifilimu ye-inki yokunyathelisa.
 
Indlela yokwandisa okuqukethwe kwe-pigment inqunyelwe ngenxa yesidingo sokunciphisa umbala ekuphrinteni umbala.Uyinki olungiselelwe ngezinhlayiya ezincane ze-pigment, lapho okuqukethwe kwe-pigment kuncipha lapho ukucwebezela kokuphrinta kuzoncishiswa, kuphela lapho ifilimu likayinki liwugqinsi impela ukukhiqiza ukucwebezela okuphezulu.Ngakho-ke, kulokhu, indlela yokwandisa okuqukethwe kwe-pigment ingasetshenziswa ukuthuthukisa ukukhanya kwezinto eziphrintiwe.Kodwa-ke, inani le-pigment lingakhuphuka lifinyelele emkhawulweni othile kuphela, ngaphandle kwalokho kuzoba ngenxa yezinhlayiya ze-pigment ezingakwazi ukumbozwa ngokugcwele yi-binder, ukuze ukukhanya okungaphezulu kwefilimu ye-inki kuqiniswe kodwa kuholele ekukhanyeni okuncishisiwe. yendaba ephrintiwe.
 
05 Ubukhulu Nokuhlakazeka Kwezinhlayiya Ze-Pigment
Ubukhulu bezinhlayiya ze-pigment esimweni sokuhlakazeka bunquma ngokuqondile isimo se-capillary yefilimu ye-inki.Uma izinhlayiya zikayinki zichama, ama-capillary amancane angakheka.Khulisa ikhono lefilimu kayinki ukuze ugcine i-binder futhi uthuthukise ukucwebezela kwezinto eziphrintiwe.Ngesikhathi esifanayo, uma izinhlayiya ze-pigment zihlakazeka kahle, kusiza futhi ukwakha ifilimu ye-inki ebushelelezi, engathuthukisa ukucwebezela kwendaba ephrintiwe.Izici ezikhawulelayo ezithinta ukusakazeka kwezinhlayiya ze-pigment inani le-pH lezinhlayiya ze-pigment kanye nokuqukethwe kwento eguquguqukayo kuyinki.Inani le-pH le-pigment liphansi, okuqukethwe kwezinto eziguquguqukayo kuyinki kuphezulu, futhi ukuhlakazeka kwezinhlayiya ze-pigment kuhle.
 
06 Ukucaca kwe-Ink
Ngemva kokwakhiwa kwefilimu kayinki obala kakhulu, ukukhanya kwesigameko kuboniswa ngokuyingxenye ebusweni befilimu kayinki, enye ingxenye yephepha elingaphezulu, bese kubonakala, kwakha umbala wokuhlunga okubili, lokhu kubonakaliswa okuyinkimbinkimbi komphumela wombala ocebile;Futhi ifilimu ye-inki eyakhiwe i-pigment opaque, ukucwebezela kwayo kubonakala kuphela ebusweni, umphumela wokucwebezela awuwona njengoyinki obala.
 
07 I-Connection Material Bushelelezi
Ukucwebezela kwe-binder kuyisici esiyinhloko sokucwebezela koyinki.I-inki binder yasekuqaleni isekelwe ikakhulukazi kuwoyela we-linseed, uwoyela we-tung, uwoyela we-catalpa namanye amafutha emifino.Ubushelelezi bendawo engemuva ye-conjunctiva ayiphezulu, ifilimu enamafutha kuphela, ukukhanya okusabalalisayo kokukhanya kwesigameko, futhi isicwebezelisi sokuphrinta asilungile.Futhi manje inhlaka ye-inki yokuxhumanisa njengengxenye eyinhloko, i-conjunctiva ephrintiwe ngemva kokuba ubushelelezi bendawo buphezulu, ukukhanya kwesigameko okuhlakazekayo kuyancipha, futhi ukucwebezela okuphrintiwe kuphakeme izikhathi eziningana kunoyinki wokuqala.
 
08 Ukungena Kwencibilika
Ukuphrinta kusanda kuphela, ngenxa yokomiswa nokulungiswa kweyinki akukaqedwa, ngakho-ke, isicwebezelisi sendawo yokuphrinta siphezulu kakhulu, njengephepha eliboshwe, indawo yayo yokuphrinta yengxenye yensimu yesicwebezelisi ivame ukuphakama ngama-degree angama-15-20. kunephepha elimhlophe, futhi ingaphezulu limanzi futhi liyacwebezela.Kodwa njengoba uyinki woma futhi uqina, ukucwebezela kuncipha kancane kancane.Uma isincibilikisi esikuyinki sisahlala ephepheni, uyinki ugcina uketshezi oluthile futhi unokushelela okuphezulu.Kodwa-ke, ngokungena kwe-solvent ephepheni, ubushelelezi bobuso bunqunywa izinhlayiya ze-pigment, futhi ngalesi sikhathi izinhlayiya ze-pigment zikhulu kakhulu kunama-molecule e-solvent, ngakho-ke, ubushelelezi bendawo yokunyathelisa Ukungena kwe-solvent futhi kwadingeka kwehle.Kule nqubo, izinga lokungena kwe-solvent lithinta ngokuqondile ukushelela nokucwebezela kwendawo yokunyathelisa.Uma ukungena kwenziwa kancane, futhi i-polymerization ye-oxidation ye-resin yenziwa ngesivinini esifanele, indawo ye-inki ingagcinwa ngokushelela okuphezulu kwesimo sokuqina kwefilimu.Ngale ndlela i-gloss yokuphrinta ingagcinwa ezingeni eliphezulu.Ngokuphambene nalokho, uma ukungena kwe-solvent kuyashesha, khona-ke ukuqina kwe-polymerization kwe-resin kungaqedwa kuphela lapho ubushelelezi bendawo yokunyathelisa buncishisiwe kakhulu, ukuze i-gloss yokuphrinta iyancipha kakhulu.
 
Ngakho-ke, esimweni sokucwebezela okufanayo kwephepha, izinga lokungena likayinki lihamba kancane, liphakamisa ukucwebezela kokuphrinta.Ngisho nasendabeni ye-gloss emhlophe kanye nezinga lokungena kweyinki kuyafana, i-gloss yokuphrinta izohluka ngenxa ye-inki yesimo sokungena ephepheni.Ngokuvamile, ngezinga lokungena elifanayo, isimo sokungena esiminyene nesicolekile sisiza kakhulu ekuthuthukisweni kwesicwebezelisi sokuphrinta kunesimo sokungena esincane nesiqinile.Kodwa ukunciphisa ukungena kukayinki kanye nesivinini se-conjunctiva ukuze kuthuthukiswe isicwebezelisi sokuphrinta kuzobangela ukwehluleka kwe-inki yokunamathela ngemuva.
 
09 Ifomu Lokomisa Uyinki
Inani elifanayo likayinki elinamafomu ahlukene okomisa, isicwebezelisi asifani, ukomiswa kwe-conjunctiva okuxubile ngokuvamile kune-osmotic drying gloss kuphezulu, ngoba i-conjunctiva ene-oxidized drying inki ifilimu yokubopha impahla.
