Ngokuthuthuka okuqhubekayo kobuchwepheshe bokunyathelisa, ukusebenza kwemishini yemikhiqizo eminingi yokunyathelisa eyaziwayo akugcinanga nje ngokuba ngcono futhi kungcono, kodwa futhi izinga lokuzenzekelayo liye lathuthukiswa ngokuqhubekayo. Isistimu yesilawuli kude sombala we-inki isiphenduke "ukumiswa okujwayelekile" kokuphrinta okuningi okuhlakaniphile, okwenza ukulawulwa kombala we-inki wemikhiqizo ephrintiwe kube lula futhi kuthembekile. Nokho, enqubweni yangempela yokuphrinta, akulula ukuzuza umbala oyinki ozinzile weqoqo ngalinye lemikhiqizo ephrintiwe. Izinkinga zekhwalithi ezibangelwa umehluko omkhulu embala we-inki zivame ukuhlangana nazo ekukhiqizeni, okubangela ukulahlekelwa enkampanini.
Ngaphambi kokuphrinta, kuyadingeka ukwenza umsebenzi omuhle wokulungiswa kwangaphambili ngokusekelwe kokuhlangenwe nakho
Okokuqala, cishe lungisa ivolumu ye-inki yomthombo we-inki weqembu ngalinye ngokwendawo yobufakazi nomaukunyathelisaipuleti. Lo msebenzi kulula ukuwuqeda emshinini ofakwe isistimu yesilawuli kude seyinki. Kufanele kube nesilinganiso esingaphezu kwama-80% salokhu. Ungalungisi ivolumu ye-inki ebangeni elikhulu ngenkathi uphrinta ukuze ugweme umehluko omkhulu wemibala.
Okwesibili, ngokwezidingo zeshidi lenqubo yokukhiqiza kanye nezici zomkhiqizo, lungisa kusengaphambili okokuphakelayo, ukuqoqwa kwephepha, ukusebenza kukayinki, usayizi wokucindezela nezinye izixhumanisi ukuze ugweme ukujaha ngesikhathi sokuphrinta okusemthethweni. Phakathi kwazo, ukuqinisekisa ukuthi i-feeder ingakwazi ukondla iphepha ngokuthembekile, ngokuqhubekayo nangokuzinzile yikona okubaluleke kakhulu. Ama-opharetha anolwazi aqale alungise kusengaphambili ukuvunguza, ukumunca, unyawo lokucindezela, isiphethu somfutho, isondo lokucindezela iphepha, igeji eseceleni, igeji yangaphambili, njll. ngokuya ngefomethi nokushuba kwephepha, qondisa ubudlelwano bokuxhumanisa ukunyakaza phakathi kwezingxenye ezahlukahlukene, qinisekisa ukuthi i-feeder iphakela iphepha kahle, futhi ugweme izinhlobonhlobo ze-inki ngenxa yokushaya kwesiphakeli. Kunconywa ukuthi izisebenzi ezinolwazi zingalungisa kusengaphambili okokuphakelayo.
Ngaphezu kwalokho, i-viscosity, i-fluidity, kanye nokoma kukayinki kufanele kulungiswe kahle kusenesikhathi ngokuya ngekhwalithi yephepha elisetshenzisiwe kanye nosayizi wesithombe nendawo yombhalo womkhiqizo ophrintiwe ukuthuthukisa ukuphrinta kwawo nokuqinisekisa ukuphrinta okuvamile. . Umbala we-inki akufanele ungalingani ngenxa yokuvalwa njalo ukuze kuhlanzwe indwangu yerabha kanye nezinwele zephepha nesikhumba sikayinki epuleti lokuphrinta. Uma izikhiqizo ezinamathelayo ezihlukene kanye namafutha kayinki kwengezwa phakathi kokuphrinta, ukuchezuka kombala kuqinisekile.
Ngamafuphi, ukwenza umsebenzi omuhle wokulungisa ngaphambili ngaphambi kokuqala umshini kunganciphisa kakhulu ukwehluleka ngemva kokunyathelisa okusemthethweni, futhi ukaputeni uzoba nesikhathi namandla okugxila embaleni kayinki.
Lungisa kahle ukucindezela kwamanzi ne-ink roller
Phakathi nenqubo yokuphrinta, isithombe nengxenye yombhalo wepuleti lokuphrinta kufanele isetshenziswe ngokuqhubekayo nangokulinganayo ngenani elifanele likayinki ukuze kutholwe ukuphrinta okunombala oyinki ongaguquki. Ngakho-ke, amarola ayinki namarola ayinki, kanye namarola ayinki nepuleti lokuphrinta, kufanele alondoloze ukuxhumana okufanele nobudlelwano bokugoqa ukuze kuzuzwe ukudluliswa kweyinki okuhle. Uma lo msebenzi ungenziwa ngokucophelela nangendlela efanele, umbala weyinki ngeke uhambisane. Ngakho-ke, ngaso sonke isikhathi lapho kufakwa ama-roller amanzi kanye ne-inki, indlela yokugoqa ibha ye-inki isetshenziselwa ukulungisa ukucindezela phakathi kwabo ngamunye ngamunye, esikhundleni sendlela yendabuko yokusebenzisa i-feeler gauge ukuhlola ukungezwani, ngoba lokhu okulandelayo iphutha elikhulu langempela ngenxa yezici ezihlukahlukene zomuntu, futhi kufanele livinjelwe emishinini enemibala eminingi kanye nesivinini esikhulu. Ngokuqondene nobubanzi bebha kayinki egoqekayo, ngokuvamile bufaneleka ukuthi bube ngu-4 kuya ku-5 mm. Okokuqala lungisa ingcindezi phakathi kwerola yokudlulisa uyinki kanye nerola yezintambo zikayinki, bese ulungisa ingcindezi phakathi kwerola yeyinki kanye nerola yezintambo zikayinki kanye nesilinda sepuleti lokuphrinta, futhi ekugcineni ulungise ukucindezela phakathi kwerola yokudlulisa amanzi, ipuleti lamanzi roller, i-roller yezintambo zamanzi, kanye ne-roller ephakathi, kanye nokucindezela phakathi kwe-plate water roller kanye ne-cylinder plate yokunyathelisa. Ibha kayinki phakathi kwale mizila yamanzi kufanele ibe ngu-6 mm.
Izinto zokusebenza zidinga ukulungiswa kabusha ngemva kwezinyanga ezimbili noma ezintathu zokusetshenziswa, ngoba ububanzi berola ye-inki buzoba buncane ngemva kwesikhathi sokungqubuzana kwesivinini esikhulu, ikakhulukazi ekudluliseni. Ingcindezi phakathi kwamarola ayinki iba mncane, futhi uyinki ngeke ukwazi ukudluliselwa lapho amarola ayinki enqwabelana kuwo. Uma isiphakeli sima isikhashana noma sima ukuze siqhubeke siphrinta, uyinki mkhulu ngalesi sikhathi, okubangela ukuthi umbala we-inki wamadazini okuqala noma amakhulu amashidi ube mnyama, futhi ibhalansi yeyinki yamanzi efanelekile kunzima ukuyifinyelela. Leli phutha ngokuvamile akulula ukulithola, futhi libonakala kakhulu lapho uphrinta amaphrinti angcono kakhulu. Ngamafuphi, ukusebenza mayelana nalokhu kufanele kucophelele futhi indlela kufanele ibe ngokwesayensi, ngaphandle kwalokho izobangela ukuthi amanzi, ibha ye-inki, umlomo nomsila wokuphrinta kube nokujula okuhlukene kwe-inki, okwenza amaphutha ngokwenziwa futhi kwandise ubunzima ukusebenza.
Ukuzuza ibhalansi kayinki wamanzi
Njengoba sonke sazi, ibhalansi ye-inki yamanzi iyingxenye ebalulekile yokuphrinta kwe-offset. Uma amanzi emakhulu futhi uyinki mkhulu, uyinki uzofakwa emulsified emanzini ngamafutha, futhi ikhwalithi yomkhiqizo ophrintiwe ngokuqinisekile ngeke ibe yinto enhle. Ngokuzijwayeza isikhathi eside, umbhali uye wahlola amasu athile.
Okokuqala, qinisekisa ukuthi ubudlelwano bengcindezi phakathi kwamanzi namarola kayinki bulungiswa kahle, futhi okuqukethwe kwesixazululo somthombo kanye notshwala be-isopropyl kuhlangabezana nezindinganiso ezijwayelekile. Ngalesi sisekelo, vula umshini, vala amanzi namarola ayinki, bese umisa umshini ukuze uhlole ipuleti lokuphrinta. Kungcono ukuba nokungcola okunamathelayo okungu-3mm kancane emaphethelweni epuleti lokuphrinta. Ukuthatha inani lamanzi ngalesi sikhathi njengenani lokuqala lamanzi lokuphrinta, ukuphrinta okuvamile kwemikhiqizo yezithombe kungaqinisekiswa, futhi ibhalansi yeyinki yamanzi ingafinyelelwa ngokuyisisekelo.
Okwesibili, inani lamanzi lingashintshwa ngokuguquguqukayo ngokuya kwezinye izinto, njengendawo enkulu yepuleti lokuphrinta, indawo elukhuni yephepha, isidingo sokwengeza izithasiselo kuyinki, isivinini sokuphrinta kanye nezinguquko izinga lokushisa lomoya kanye nomswakama.
Ngaphezu kwalokho, umbhali uphinde wathola ukuthi lapho umshini usanda kuqala ukuphrinta, izinga lokushisa lomzimba liphansi, futhi lapho umshini ugijima ngesivinini esikhulu ihora elilodwa noma amabili, izinga lokushisa lomzimba, ikakhulukazi izinga lokushisa le-roller yerabha, lizokwenza. ikhuphuke ngaphezu kokuphindwe kabili, noma ngaphezulu. Ngalesi sikhathi, inani lamanzi kufanele lenyuke kancane kancane kuze kube yilapho i-inki yamanzi ifinyelela ibhalansi entsha.
Kungabonakala ukuthi akulula ukuzuza ibhalansi ye-inki yamanzi, futhi u-opharetha udinga ukukala futhi asebenzise ngolimi. Uma kungenjalo, ukuqina kombala we-inki kunzima ukulawula, futhi imikhiqizo ephrintiwe yekhwalithi ephezulu ayikwazi ukuphrinta.
Ukuhlola nokuhlelwa kokulandelana kombala
Ekukhiqizeni, sivame ukuhlangana nesimo esinjalo: isampula esinikezwe ikhasimende aliyona into evamile, noma kuphela uhlaka lwe-inkjet lombala olunikezwa ngaphandle kobufakazi. Ngalesi sikhathi, sidinga ukuhlaziya isimo esithile, futhi asikwazi ukusebenzisa indlela yokwandisa ngokuqinile noma ukunciphisa umthamo we-inki ukuxosha umphumela wobufakazi. Ngisho noma kuseduze nobufakazi ekuqaleni, ukuzinza kombala we-inki akunakuqinisekiswa, futhi ngaleyo ndlela ikhwalithi yokugcina yomkhiqizo ophrintiwe ayikwazi ukuqinisekiswa. Mayelana nalokhu, imboni yokunyathelisa kufanele ikhulume ngenkuthalo nekhasimende ngesimo sengqondo esingathi sína nesinomthwalo wemfanelo, ibonise izinkinga neziphakamiso zokuguqulwa kwesampula, futhi yenze izinguquko ezifanele ngaphambi kokunyathelisa ngemva kokuthola imvume.
Ekukhiqizeni, ukulandelana kombala wokuphrinta womshini wemibala eminingi ngokuvamile kunqunywa i-viscosity yeyinki. Njengoba ekuphrinteni ngemibala eminingi, uyinki ugqitshwa ngendlela emanzi-emanzi, kuphela ngokuthola isilinganiso esingcono kakhulu se-superimposition lapho umbala we-inki ozinzile nongashintshi ungaphrintwa. Ukuhlelwa kokulandelana kombala wokuphrinta kufanele kuhambisane nezici nezidingo zekhwalithi zomkhiqizo ophrintiwe, futhi akukwazi ukuhlala kungashintshiwe. Ngesikhathi esifanayo, i-viscosity ye-inki nayo ingashintshwa. Isibonelo, ikhava ensomi kanye nesembozo esiluhlaza okwesibhakabhaka esisibhakabhaka sinokulandelana kwemibala ehlukene yokuphrinta: i-cyan yokuqala ne-magenta yesibili kweyangaphambili kanye ne-magenta yokuqala kanye neyesibili cyan kokugcina. Uma kungenjalo, imibala ephrintiwe ngokweqile izobonwa, engebushelelezi futhi iqinile. Isibonelo, ngokuphrinta okumnyama ikakhulukazi, okumnyama kufanele kufakwe eqenjini lemibala yokugcina ngangokunokwenzeka. Ngale ndlela, ukucwebezela komnyama kungcono futhi imihuzuko nokuxubana kombala ngaphakathi komshini kuyagwenywa.
Hlakulela imikhuba emihle yokusebenza futhi uqinise umthwalo wemfanelo wokusebenza
Lapho senza noma yimuphi umsebenzi, kufanele sibe nomuzwa ophezulu wokuba nomthwalo wemfanelo kanye nomuzwa oqinile wekhwalithi. Kufanele simise inqubo yokusebenza futhi sibambelele emikhubeni emihle yendabuko efana "namazinga amathathu" kanye "nokukhuthala okuthathu". Thatha ukuqhathanisa okuvamile kwamasampuli njengesibonelo. Uma uqhathanisa isampuli yesiginesha kusampula, ngenxa yokuhluka kwebanga, i-engeli, umthombo wokukhanya, njll., okubonakalayo kuzochema, okuholela kumbala we-inki ongahambisani. Ngalesi sikhathi, isampula yesiginesha kufanele ikhishwe kusampula futhi iqhathaniswe ngokucophelela; ipuleti lokuphrinta elisebenza isikhathi eside lidinga ukubhakwa ukuze kuncishiswe ukuchezuka kombala we-inki okubangelwa ukushintsha kwamapuleti; indwangu yenjoloba kufanele ihlanzwe kaningi, futhi iphepha lokusula kufanele libekwe ngaphezulu ngemva kokuhlanza ngakunye ukuze umbala uyinki uzinze; ngemva kokuba i-feeder imisiwe okwesikhashana, amashidi amahlanu noma ayisithupha asanda kunyatheliswa amnyama kakhulu futhi adinga ukukhishwa. Isivinini sokuphrinta akufanele sisheshe kakhulu. Okubalulekile wukugcina umshini uzinzile futhi ujwayelekile; lapho wengeza uyinki emthonjeni kayinki, ngenxa yokuthi uyinki omusha unzima futhi unoketshezi oluncane, kufanele uguquguquke izikhathi eziningana ukuze ugweme ukuthikameza inani likayinki futhi ubangele ukuchezuka kombala we-inki.
Ama-opharetha kufanele aqhubeke nokufunda, ukubheka nokuhlaziya ngokucophelela, bathole izici ezithinta ukuguqulwa kombala we-inki kuzo zonke izici, futhi bathathe izinyathelo ezihambisanayo ukuze bazivikele kahle futhi bazinqobe, balwele ukwenza ngcono ukuzinza nokuvumelana kombala we-inki we-inki. imikhiqizo ephrintiwe, futhi ithuthukise ngempumelelo ikhwalithi yemikhiqizo ephrintiwe.
