I-Ink Factors Ethinta I-Print Gloss
1 Ukujiya kwefilimu kayinki
Ephepheni ukuze kwandiswe ukumuncwa kukayinki ngemva kwesixhumi, isixhumi esisele sisagcinwe kufilimu kayinki, engathuthukisa ngempumelelo isicwebezelisi sokuphrinta.Uma ifilimu kayinki iba mkhulu, kulapho isixhumi esisele siba sikhulu kakhulu, kuba ngcono kakhulu ekuthuthukiseni ukucwebezela kokuphrintiwe.
Icwebezela ngokukhula kobukhulu befilimu kayinki nokwanda, naphezu koyinki ofanayo, kodwa ukwakheka kwegloss yokuphrinta ehlukile yephepha enobukhulu befilimu kayinki noshintsho kuhlukile.Iphepha elicwebezelayo eliphakeme elifakwe kwifilimu kayinki lincane, ukuphrinta isicwebezelisi nokwanda kokuqina kwefilimu kayinki futhi kuncishiswe, lokhu kungenxa yefilimu ye-inki efihla iphepha ngokwalo i-gloss ephezulu yoqobo, kanye nefilimu ye-inki ngokwayo eyakhiwe yi-gloss futhi ngenxa ukumuncwa kwephepha nokunciphisa;ngokwanda kancane kancane kobukhulu befilimu kayinki, iphepha ekumunceni kokuxhumanisa ligcwala ngokuyisisekelo ngemva kokwanda kwenani lezinto ezixhumeneyo ezigcinwe phezulu, futhi isicwebezelisi sithuthuka njalo.
Amaphrinti ekhadibhodi ahlanganiswe acwebezela ngokwanda kogqinsi lwefilimu kayinki akhuphuka ngokushesha, ugqinsi lwefilimu kayinki lukhuphuke lwaba ngu-3.8μm ngemuva kokuthi isicwebezelisi ngeke sisakhula ngokukhula kokuqina kwefilimu kayinki.
2 Uketshezi lukayinki
Uketshezi lukayinki lukhulu kakhulu, ichashazi liyakhula, usayizi wokuphrinta uyanwetshwa, isendlalelo sikayinki siba mncane, isicwebezelisi sokuphrinta simpofu;I-inki fluidity incane kakhulu, isicwebezelisi esiphezulu, uyinki akulula ukuyidlulisela, kodwa futhi ayihambisani nokuphrinta.Ngakho-ke, ukuze uthole isicwebezelisi kangcono, kufanele alawule fluidity uyinki, hhayi enkulu kakhulu hhayi encane kakhulu.
3 Ukulinganisa kukayinki
Enqubweni yokunyathelisa, ukulinganisa kweyinki kuhle, khona-ke i-gloss yinhle;izinga eliphansi, kulula ukulidonsa, khona-ke isicwebezelisi simpofu.
4 Okuqukethwe kwe-pigment kuyinki
Okuqukethwe kwe-pigment ephezulu kukayinki kungakha inani elikhulu lama-capillary amancane ngaphakathi kwefilimu kayinki.Futhi lezi nombolo enkulu yokugcinwa kwe-capillary emihle yekhono lokuxhumanisa impahla, kunobuso bephepha begebe lefayibha ukumunca ikhono lokuxhumanisa impahla likhulu kakhulu.Ngakho-ke, uma kuqhathaniswa noyinki abanombala ophansi, oyinki abanombala ophakeme bangenza ifilimu kayinki igcine i-linker eyengeziwe.Ukucwebezela kwento ephrintiwe kusetshenziswa iziyinki ezinokuqukethwe kwe-pigment ephezulu kuphakeme kunaleyo kayinki anokuqukethwe kombala ophansi.Ngakho-ke, isakhiwo senethiwekhi ye-capillary esakhiwe phakathi kwezinhlayiya ze-ink pigment iyisici esiyinhloko esithinta ukucwebezela kokuphrinta.
Ekunyatheliseni kwangempela, ukusetshenziswa kwendlela kawoyela we-gloss ukwandisa isicwebezelisi sokuphrinta, le ndlela ihluke ngokuphelele endleleni yokwandisa okuqukethwe kwe-pigment kayinki.Lezi zindlela ezimbili zokwandisa isicwebezelisi sokuphrinta kuhlelo lokusebenza, ngokusho kwezingxenye ze-inki nokuphrinta ifilimu ye-inki ukujiya ongakhetha.
Indlela yokwandisa okuqukethwe kwe-pigment inqunyelwe isidingo sokukhiqiza umbala ekuphrinteni umbala.Uyinki owenziwe ngezinhlayiya ezincane ze-pigment, lapho okuqukethwe kwe-pigment kuncipha, i-gloss yokuphrinta iyancipha, kuphela uma ifilimu likayinki liwugqinsi impela ukukhiqiza ukucwebezela okuphezulu.Ngakho-ke, indlela yokwandisa okuqukethwe kwe-pigment ingasetshenziswa ukuthuthukisa isicwebezelisi sendaba ephrintiwe.Kodwa-ke, inani le-pigment linganyuswa kuphela libe umkhawulo othize, ngaphandle kwalokho kuyoba ngenxa yezinhlayiya ze-pigment azikwazi ukumbozwa ngokuphelele yizinto ezixhumanisayo, ukuze ifilimu ye-ink surface ukukhanya okuhlakazekayo kubhebhetheke esikhundleni sokuholela ku-a. ukuncishiswa kokucwebezela kwento ephrintiwe.
5Ubukhulu bezinhlayiya ze-pigment kanye nezinga lokuhlakazeka
Ubukhulu bezinhlayiya ze-pigment esimweni esihlakazekile bunquma ngokuqondile isimo se-ink film capillary, uma izinhlayiya ze-inki zincane, zingakha i-capillary encane kakhulu.Khulisa ikhono lefilimu kayinki ukuze ugcine isixhumi futhi uthuthukise ukucwebezela kokuphrinta.Ngesikhathi esifanayo, uma izinhlayiya ze-pigment zihlakazeka kahle, kusiza futhi ukwakha ifilimu ye-inki ebushelelezi, engathuthukisa ukucwebezela kokuphrinta.Izici ezilawulayo ezithinta izinga lokuhlakazwa kwezinhlayiya ze-pigment yi-pH yezinhlayiya ze-pigment kanye nenani lezinto eziguquguqukayo kuyinki.Ukuhlakazwa kwezinhlayiya ze-pigment kuhle uma inani le-pH le-pigment liphansi futhi okuqukethwe kwezinto eziguquguqukayo kuyinki kuphezulu.
6Ukungafihli kukayinki
Ngemva kokuba ifilimu kayinki kwakheka uyinki ngokukhanyela okuphezulu, ingxenye yokukhanya kwesigameko iboniswa ubuso befilimu kayinki, futhi enye ingxenye ifinyelela phezu kwephepha futhi iphinde ibonakale, yenze ukuhlunga kwemibala emibili, futhi lokhu ukucabangela okuyinkimbinkimbi kuthuthukisa umphumela wombala;kuyilapho ifilimu likayinki elakhiwe umbala opaque licwebezela kuphela ngokubonakala kwendawo, futhi umphumela wokucwebezela awumuhle neze njengokayinki obala.
7Isicwebezelisi sezinto zokuxhuma
Ukucwebezela kwezinto zokuxhuma kuyisici esiyinhloko sokuthi ukuphrinta kweyinki kungakhiqiza isicwebezelisi, inki yokuqala yokuxhuma i-linseed oil, i-tung oil, i-catalpa oil namanye amafutha emifino, ubushelelezi bobuso befilimu ngemuva kokuthi ifilimu hhayi phezulu, ingabonisa kuphela indawo yefilimu enamafutha, ukukhanya kwesigameko ukuze kwakhiwe ukubonakaliswa okusabalalisayo, isicwebezelisi sokuphrinta simpofu.Kulezi zinsuku, into yokuxhuma kayinki ngokuyinhloko yenziwe nge-resin, futhi ukushelela kwe-inki ngemuva kokumbozwa kuphezulu, futhi ukukhanya okusabalele kokukhanya kwesigameko kuyancipha, ngaleyo ndlela ukucwebezela kukayinki kuphakeme izikhathi eziningana kuno uyinki wokuqala.
8Indlela yokomisa kayinki
Inani elifanayo likayinki usebenzisa izinhlobo ezahlukene zokomisa, isicwebezelisi asifani, ngokuvamile ukomisa ifilimu ene-oxidized kunokungena isicwebezelisi esomile siphezulu, ngoba ifilimu ene-oxidized omiswe uyinki in the material linker forming ifilimu kakhudlwana.
Indlela yokuthuthukisa isicwebezelisi sokuphrinta?
1 Yehlisa ukwenziwa kwe-inki emulsification
Yehlisa izinga le-inki emulsification.Ukuphrinta kwe-offset ku-emulsification ye-inki kubangelwa ukusebenza kwamanzi noyinki, ukuphrinta kubukeka njengongqimba oluwugqinsi lukayinki, kodwa ama-molecule kayinki angena esimweni samafutha emanzini, i-gloss yokomisa impofu kakhulu, futhi izokhiqiza uchungechunge. kokunye ukwehluleka.
2 Izithasiselo ezifanele
Engeza izinsiza ezifanele kuyinki, ungakwazi ukulungisa ukuphrinta kweyinki ukuze uphrinte kahle.Izinsiza ezijwayelekile zengezwe emalini kayinki, akufanele zidlule u-5%, uma ucabangela umphumela we-gloss, kufanele ube ngaphansi noma ungafaki.Kodwa i-surfactant ye-fluorocarbon ihlukile, ingavimbela ungqimba lweyinki lwekhasi le-orange, imibimbi kanye nezinye iziphambeko ezingaphezulu, futhi ngesikhathi esifanayo kungathuthukisa ubuso be-gloss yokuphrinta.
3 Ukusetshenziswa okufanele kwamafutha omisiwe
Ukusetshenziswa okufanele kwamafutha omisiwe.Kuyinki ephezulu ecwebezelayo eyomisa ngokushesha, esimweni sokushisa nomswakama kuyinto evamile, ngokwayo inomthamo owanele wokumisa.
Uma kunezimo ezilandelayo, uwoyela owomisa kufanele wengezwe:
① Uma izinga lokushisa eliphansi kanye nomswakama ebusika;
② uyinki kufanele wengezwe ku-anti-Adhesive, anti-adhesive, uwoyela wokulungisa uyinki omncane, njll., kufanele wengezwe emafutheni omisa.
Ekusebenzeni kwenqubo, ukusetshenziswa okufanele kwamafutha omile, ukwakheka kwe-gloss yomkhiqizo ophelile kuhle kakhulu.Lokhu kungenxa yokuthi iphepha ukuze limunce impahla yokuxhumanisa idinga isikhathi esithile, kule nqubo, ngokushesha ngangokunokwenzeka ukwenza isixhumanisi sezinto ezibonakalayo, kuze kube yilapho ifilimu isomile, iyisihluthulelo se-gloss yomkhiqizo ophelile.
4 Ukulungiswa Komshini
Lungisa kahle umshini.Ukuthi ukujiya kwesendlalelo sikayinki sokuphrinta kufinyelela ezingeni, nakho kunomthelela ekucwebezeleni.Isibonelo: ukulungiswa kwengcindezi embi, izinga lokunwetshwa kwamachashazi liphezulu, ukujiya kongqimba lukayinki akuhlangabezani nendinganiso, isicwebezelisi somkhiqizo oqediwe siba sibi kakhulu.Ngakho-ke, ukulungisa ingcindezi, ukuze ukulawulwa kwezinga lokunwetshwa kwamachashazi cishe ku-15%, ungqimba lukayinki womkhiqizo ophrintiwe luwugqinsi, izinga nokudonsa kuvuleke, isicwebezelisi sikhona.
5 Lungisa ukugxila kweyinki
Engeza amanzi e-Fanli (amafutha angu-0), le viscosity yamafutha inkulu kakhulu, iminyene, ingalungisa ukugxila kweyinki, ukuze inkino encane ikhule, ikhulise isicwebezelisi somkhiqizo ophrintiwe.
