izindaba

Isingeniso: Isithombe sangaphandle sezimpahla emqhudelwaneni oshubile wemakethe siya ngokuya sibaluleke kakhulu, ibhokisi lombala ngenxa yezinga eliphezulu, elithambile, elihle liba yisinqumo esingcono kakhulu sesithombe sangaphandle sokupakishwa kwempahla, ibhokisi lombala alisona isisindo esilula kuphela. , kulula ukuthwala, inhlobonhlobo yezinto ezingavuthiwe, futhi inokuvikelwa kwemvelo okuhle kakhulu.Lesi sihloko sabelana ngezinto ezingu-8 ezithinta ikhwalithi yokuphrinta kwebhokisi lombala, okuqukethwe kwabangane ukuze kusetshenziswe ireferensi:

Ibhokisi Lombala

Ibhokisi lombala libhekisela ebhokisini lephepha eligoqayo kanye nebhokisi lephepha likathayela elincane elenziwe ngekhadibhodi nephepha likathayela.Ngokuvamile isetshenziswa njengendlela yokupakisha emaphakathi nebanga, phakathi kokupakisha kwangaphakathi nebhokisi langaphandle.

01 Umthelela Wefilimu

Inqubo yokuthuthukisa nokulungisa ifilimu ngemva kokuchayeka ihlobene ngokuqondile nokucijile nokugqama kwesithombe kufilimu.Ngakho-ke, efilimini yepuleti, isihluthulelo sokubheka umbhalo kanye nombhalo ingxenye yobuningi kanye nombhalo kanye nengxenye yombhalo kanye nengxenye engeyona yombhalo yokuphambene.Ukuphakama kokuminyana, umehluko omkhulu, ikhwalithi yefilimu engcono kakhulu, ngokukhiqizwa kwayo kwekhwalithi yokuphrinta amapuleti kungaqinisekiswa.Ngaphezu kwalokho, ukushuba kwesisekelo sefilimu okwenza amapuleti nakho kunomthelela kwikhwalithi yokwenziwa kwamapuleti, ngokuvamile ifilimu elincanyana lingcono kunefilimu eliwugqinsi.

02 Inguqulo Yelanga Yomthelela

Enqubweni yokuphrinta, ukushuba komthombo wokukhanya, ibanga phakathi komthombo wokukhanya nepuleti, nobude besikhathi sokuchayeka kuzothinta ikhwalithi yokuphrinta.Umthombo wokukhanya unamandla, ibanga lifushane futhi isikhathi sokuchayeka sifushane.Umthombo wokukhanya ubuthakathaka, ibanga lide futhi isikhathi sokuchayeka side kakhulu.Ngaphansi komthombo othile wokukhanya nebanga, ngokukhula kwesikhathi sokuchayeka, ukubola kwefilimu kuqina engxenyeni yokukhanya yepuleti kuze kube yilapho ifilimu isibole ngokuphelele.Uma isikhathi sokuchayeka siqhubeka sikhula, ungaboni ingxenye yokukhanya yonqenqema lwefilimu ngenxa yemisebe eqinile, ifilimu ye-photosensitive nayo yaqala ukubola kancane kancane, ukuze imigqa yengcweti yepuleti ibe mncane, iphuke imbala, ifiphale.Uma isikhathi sokuchayeka singanele, ingxenye engeyona i-graphic ye-optical drug film surface ayiboli ngokuphelele, futhi ingxenye engeyona ingcaca yokuthuthukiswa kwepuleti iseyifilimu yezidakamizwa, futhi ukuphrinta komshini kuzobe kungcolile.Ngaphezu kwalokho, izinhlobo ezahlukene zepuleti lokuphrinta ezidingekayo isikhathi sokuchayeka azifani, okumele zidonse ukunaka kwabantu.

Ngaphezu kwalokho, ku-vacuum yepuleti okomisa, ifilimu kanye nepuleti eliseduze nezinga lokuchayeka kwikhwalithi yepuleti, uma ukunamathisela kungekona okwangempela, ipuleti lokunyathelisa lingase livele kabili, ukungaqondakali nezinye izinkinga.

03 Umthelela Wentuthuko

Ukugxilisa ingqondo konjiniyela

I-concentration yonjiniyela inkulu kakhulu, ikhula ngokushesha kakhulu, kulula ukubangela ukuthuthukiswa ngokweqile kwepuleti lokuphrinta, imigqa emincane yombhalo nombhalo, ukulahlekelwa kwamachashazi amancane noma umbhalo omncane nombhalo awucacile, othinta ikhwalithi yokuphrinta ibhokisi lombala;Ukugxilisa ingqondo kanjiniyela kuncane kakhulu, bheka ukubola okukhanyayo kwendawo yefilimu yezidakamizwa akulula ukuyihlanza, kulula ukuyingcolisa lapho kunyatheliswa.

Ukuthuthukisa Isikhathi

Isikhathi sokuthuthukisa side kakhulu, indawo yefilimu yezidakamizwa yepuleti ayiboni ukukhanya kulula ukuchithwa, isithombe sepuleti kanye nombhalo kuzoba lula futhi kube mncane, okuholela ekunyatheliseni kokunyathelisa akuyona into yangempela, engacacile;Isikhathi sokuthuthukisa sifushane kakhulu, bheka ukubola okukhanyayo kwendawo yefilimu yezidakamizwa akulula ukucacisa ngokuphelele, ukuphrinta okulula okungcolile.Isikhathi esifanele sokuthuthukiswa singemva kokuthuthukiswa kwepuleti lokuphrinta hlambulula, bheka ukubola okukhanyayo kwendawo yefilimu vele uhlanza.Uma ukugcwala koketshezi kukhulu, isikhathi sokukhula kufanele sifinyezwe ngokufanele.Ngokuphambene, isikhathi sokuthuthukisa kufanele selulwe ngokufanele.

04 Umphumela Wokudlulisa Uyinki

Inqubo yokuphrinta empeleni iyinqubo yokudlulisa uyinki, ngokuvamile, izinga lokudlulisa uyinki wokuphrinta liphansi, cishe ngama-38%.Ipuleti lokuphrinta ukuthintana noyinki ngengubo, izinga lokudlulisa uyinki lilinganiselwa ku-50%, ingubo yokulala kanye nokuxhumana kwephepha, izinga lokudlulisa uyinki lilinganiselwa ku-76%.Ngakho-ke, ukulawulwa kwezinga lokudlulisa uyinki kubaluleke kakhulu.Ukufaneleka kukayinki, ibhalansi kayinki, ipuleti, ukusebenza kwengubo nephepha, umshini wokunyathelisa kuzothinta ukudluliswa kukayinki.

Ukusebenza kukayinki Ekudluliselweni kwe-Ink

I-viscosity ephansi, i-liquidity yeyinki kulula ukuyidlulisela, izinga lokudlulisa liphezulu;I-viscosity ephezulu, i-fluidity ephansi yezinga lokudlulisa uyinki liphansi.Ukuze sithuthukise izinga lokudlulisa uyinki, kufanele silawule i-viscosity kanye ne-fluidity ye-inki.Ukusebenza kweyinki kuzoshintsha nemvelo, izinga lokushisa eliphezulu, i-viscosity ye-inki iphansi, izinga lokushisa eliphansi, i-viscosity ye-inki iphakeme.Ekukhiqizeni kwangempela, kufanele kusekelwe esimweni sangempela ukukhetha izinhlobo ezahlukene, izinhlobo kanye nezindlela ezahlukene zokumisa zikayinki.Ngaphezu kwalokho, ku-inki yokwengeza inani elifanele likawoyela oyinki, kungalungisa ukusebenza kweyinki, kungasiza ukulawula ukwanda kwamachashazi, kuthuthukise izinga lokudlulisa uyinki.

05 Ukusebenza Kwengubo Ekudluliselweni Kweyinki

Ingubo kufanele ibe nokumuncwa kahle kukayinki nokudluliswa kukayinki, kodwa futhi kufanele ibe nokuphikiswa kukawoyela, ukumelana ne-asidi, ukumelana ne-alkali, ukunwebeka okuhle nezinye izici.Uma ingubo ingahlanzwa kahle ngemva kokunyathelisa, inki eboshwe ku-villi izoqinisa kancane kancane i-conjunctiva, isakhiwo se-villi se-rubber surface sonakaliswe, sithinte ngokuqondile izinga le-inki yengubo, ngaleyo ndlela yehlise izinga lokudlulisa inki yengubo. .Ngakho-ke, ngemva kokunyathelisa, ingubo kufanele igezwe kahle.Uma isikhathi sokuphumula siside uma kuqhathaniswa, ungqimba lwempuphu ye-pumice lungakhuhlwa ngaphezulu, ukuze ingaphezulu lengubo lihlale ligcina isakhiwo sokuqala esinonya, futhi siqinisekise ukuthi ingubo inokumuncwa kahle kukayinki kanye nokudluliselwa kukayinki.

Umthelela we-Paper Fit

Ukufaneleka kwephepha kubonakala kakhulu ngokushelela, ubumhlophe, ukuqina nezinye izici.Ubushelelezi bephepha leyinki elidingekayo lincane uma kuqhathaniswa;Ubushelelezi bephepha kwakudinga inani elikhulu likayinki.Enqubweni yokunyathelisa, iphepha elihlukile ngokwemibandela yalo ehlukene yendawo, inani leyinki elidingekayo ukuze lishintshe ngokufanele.Ezinhlobonhlobo ezifanayo, inani elifanayo, izimo zentengo efanayo, ubushelelezi, ubumhlophe yiphepha eliphakeme kunobushelelezi, ubumhlophe yikhwalithi ephansi yokuphrinta iphepha.

06 Umthelela Wokufaneleka Kwepuleti

Izinga lesihlabathi se-plate base sand, i-hydrophilic metal plate kanye nokunameka kwefilimu ye-polymer resin kuhlobene nokufaneleka kwepuleti lokuphrinta, okuthinta ukudluliswa kukayinki kanye nebhalansi yepuleti likayinki.Enkambweni yokwenza ipuleti, ukuchayeka, ukuthuthukiswa kuzophinde kuthinte ukusebenza kwepuleti.

07 Umthelela Webhalansi Kayinki

Ibhalansi yokudweba uyinki ibhalansi ehlobene, hhayi ibhalansi ephelele.Enqubweni yokusebenza kwesivinini esikhulu semishini, ingxenye eyingcaca yepuleti lokunyathelisa kanye nengxenye ye-inki engeyona ingcaca, namanzi, ukungena ngokuhlanganyela, ngakho ipuleti lokunyathelisa libophekile ukukhiqiza i-emulsification ye-inki.Uma inani lamanzi noyinki lingalawulwa kahle, libophezelekile ukujulisa i-emulsification kayinki, okuholela ekunyatheliseni inguqulo efiphele, inguqulo engcolile.Ukuphrinta kuvame ukusetshenziselwa ukunciphisa inani lamanzi, ukwanda okufanele kwenani likayinki, kodwa ngezinye izikhathi futhi kunciphise inani likayinki.Ukwengeza, i-emulsification ye-inki izoshintsha ngokushintsha kwezimo zemvelo, ekukhiqizeni ukuphrinta kwangempela, kufanele kusekelwe esimweni sangempela, ukubamba i-viscosity ye-inki kanye nenani le-pH lesisombululo somthombo ukulawula inani likayinki namanzi, ukuze ipuleti inguqulo engafiphaziwe, hhayi inguqulo engcolile njengophawu lokuma.
