Umthelela wokuphrinta wephepha elinamabhande amabili uthambile futhi uyavumelana, unomuzwa wokulandelana.Kodwa-ke, ukusebenza kokuphrinta kwephepha elinebhande eliphindwe kabili kubi, ngakho-ke izindaba ezimbalwa kufanele ziphawulwe ekuphrinteni okunamabhande amabili.
1. Iphepha elinamathiselwe kabili elinamathelayo, ngenxa yezinga elimpofu le-double-adhesive paper sizing emakethe, ukususa kalula izinwele kanye nempushana, ngakho-ke ekukhetheni kukayinki kufanele ukhethe ukuphrinta kwe-inki ethambile.Uyinki uqinile, uyinki ebukekayo kakhulu kulula ukudonsa indawo enamathelayo yempushana yephepha nezinwele zephepha, okuholela ekunqwabeleni kwengubo yenjoloba, ukudluliswa okubi, ukugeleza kwe-inki, ukusebenza kahle okuphansi, ukulahlekelwa kwephepha, ingubo yenjoloba kanye nezinga lokugqoka ipuleti lokuphrinta. umpofu.Ngaphezu kwalokho, ukucindezela kokunyathelisa kufanele kube okuphakathi, kungabi kukhulu kakhulu.Futhi ingubo yenjoloba kufanele ikhethe indawo engcono yenjoloba, akulula ukuyilimaza, ukuqina okuhle kwengubo yerabha.
2. Izinkinga zokumuncwa kwephepha elinamathela kabili, umenzi wephepha elinamathelisa kabili elinokufakwa kweyinki enamandla, ukumuncwa kwamanzi, ngakho ukukhetha kukayinki kufanele kukhethe izinga eliphezulu lombala futhi kungangena ku-inki owomile.Uma ukugxila kombala kungephezulu, ungqimba lukayinki luwugqinsi, iphepha limunca amanzi amaningi lapho linyatheliswa, futhi uyinki nephepha kome kancane.Ngaphezu kwalokho, uma uyinki surface ifilimu omiswe fast kakhulu, kungase kuthinte phansi omiswe Ukungena iphepha, okuholela omiswe phezu ukunyathelisa, ukusika iphepha, ukubopha kanye nezinye izinqubo okubangelwa iphepha is hhayi omile ngaphakathi kanye nezinye izinkinga.
3. inani le-PH elinamathelayo eliphindwe kabili, njengoba inani le-PH lephepha lokunamathisela eliphindwe kabili emakethe liyi-asidi ebuthakathaka, ngakho-ke isisombululo sokumanzisa asikwazi ukuba ne-acidic kakhulu, inani le-PH livame ukusethwa cishe ku-5.5, ukugxila kusethwe ku- cishe u-12-15%, okulungele ukuphrinta nokomisa.Ngaphezu kwalokho, enqubweni yokunyathelisa, ukulawula okuqinile kwamanzi, izinga lamanzi le-inki yokuqala yesikhathi kanye nezinga likayinki akumele kube phezulu kakhulu.Endabeni yokunyathelisa amapuleti ayikwazi ukumelana ezingcolile, amanzi kanye uyinki supply kufanele kube kancane ngangokunokwenzeka ukuze ngokushesha ukufinyelela ibhalansi uyinki, amanzi kanye uyinki ukuba kuncane, ukuphrinta kube kuncane.
Akudingekile ukulenga inethiwekhi ye-150, inethiwekhi ye-133, ngezinye izikhathi imigqa engu-200 yokuphrinta imiphumela engcono.Ngaphezu kokukhiqizwa kwangaphambi kokucindezela, ukucaba kwezinhlangothi ezimbili zephepha nakho kwenza umehluko omkhulu, uhlangothi olubi lwesithombe esiphrintiwe kunzima ukubukeka lungenangqondo.Ngakho-ke, zama ukukhetha ukushelela okuhle kwephepha.Abakhiqizi bephepha abahlanganiswe kabili bokuphrinta kombala wephepha elinezimo ezimbili ezinhle kakhulu izimo zemiphumela emihle: ukuze uqinisekise ikhwalithi yemikhiqizo ephrintiwe ukuhlangabezana nezidingo zamakhasimende, udinga ukulawula isixhumanisi ngasinye.Ukulawulwa kwekhwalithi yepuleti lokuphrinta lephepha elinamekwe kabili, ukuphrinta, kukhuphule kancane ukuchayeka kwangempela, ukuze amachashazi asepuletini kunamachashazi akufilimu abe mancane kancane ukunxephezela ukwanda kwamachashazi okubangelwa ingcindezi ngesikhathi sokuphrinta.
Enkambweni yokubhaka ipuleti, ipuleti enkambisweni yokupholisa kusuka emakhazeni bese ishisa, izokhiqiza i-elongation ehambisanayo, i-shrinkage phenomenon.Ngakho-ke, ukuze kuqinisekiswe ukunemba kokuphrinta ngokweqile, ukuphrinta ngemibala eminingi ngokuvamile akukhuthazwa.Inombolo yamapuleti alungisiwe kufanele abe nekhono futhi anembile, futhi anciphise inani lamapuleti alungisiwe ukuze agweme ukuphrinta ngokweqile okungalungile ngenxa yokwelulwa kokwenziwa kanye nokuguqulwa kwepuleti lokuphrinta.Ukulawula izimo zokuphrinta zomkhiqizi wephepha elinamekwe kabili: isixazululo sokumanzisa isilawuli senani le-PH ku-5.5 ~ 6.5.Uma inani elingu-PH lesisombululo sokumanzisa lingalawulwa kahle, lizophazamisa ukomiswa kweyinki nekhwalithi yokuphrinta.Lapho unyathelisa, ukulawula okuqinile kwesakhiwo somswakama, ukugcina ibhalansi yeyinki noyinki, ukufeza "amanzi amancane ayinki omile" isimo esihle kakhulu sokunyathelisa.Izinga lokushisa lokusebenzela kanye nokulawula umswakama.
