Namuhla, imishini yokunyathelisa isikrini isetshenziswe kabanzi ezimbonini ezihlukahlukene.Emkhiqizweni wokuphrinta isikrini wemishini yokuphrinta isikrini, izikrini zokuphrinta isikrini azikwazi ukungcoliswa, kodwa ngokuvamile sisebenzisa imishini yokuphrinta isikrini ukuze sibuke ngokuhlukile.Izinhlobo zemikhiqizo zivame ukubangela ukuthi ukungcola esibukweni kuhlanzwe, okuholela ekumosheni, okuthinta ikhwalithi yokuphrinta kanye nokunciphisa impilo yesevisi yesifanekiso.Ngakho-ke iyiphi indlela yokunciphisa isikrini somshini wokuphrinta isikrini?
Uma kukhona ukungcola noma uyinki omile engxenyeni ephrintiwe yesithombe, isikrini kufanele sicishwe.Ngemuva kokumisa ukucindezela, uhlaka luzophakanyiswa.Ngalesi sikhathi, abanye opharetha bazosebenzisa indwangu e-abrasive ukuhlikihla isifanekiso.Ohlangothini olungezansi, umsindo uphakeme ngokwanele ukuba uzwakale kuso sonke isitolo sokunyathelisa, futhi isifanekiso sivame ukonakala.
Umsebenzisi onolwazi lwangempela akavamile ukusebenzisa amandla ukuze ahlikihle indawo ephrintiwe nge-stencil ngenxa yokuthi uyazi ukuthi ukucaca kwesithombe esiphrintiwe kudinga ukuthi zonke iziphetho zesithombe zihlale zicacile ngesixhumi esibonakalayo sesithombe se-emulsion.Ukuhlikihla kanzima kungalimaza isixhumi esibonakalayo sesendlalelo se-emulsion, ngisho nokuhlikihla isendlalelo se-emulsion, kushiye anezikhala ezingenalutho.
Lapho uphrinta izithombe zombala we-net-line ephezulu, ifilimu ye-emulsifier ngaphansi kocingo ingu-5-6um kuphela ubukhulu, futhi ububanzi bemeshi bemeshi ngokwayo bungase bube ngu-30um kuphela, obungenakukhuhlwa kanzima.Ngakho-ke, isihluthulelo sokugwema ukungcoliswa okunamandla ukuvimbela i-stencil ukuthi ingangcoliswa kuqala.
Isizathu esiyinhloko sokungcola kwe-stencil ukulawulwa kwe-inki okungalungile, okubangela ukuthi uyinki owomile uhlale e-mesh.Uma kusetshenziswa uyinki osuselwe kuncibilikisiwe noma uyinki onamanzi, isizathu siwukuthi uyinki mncane kakhulu noma uwugqinsi kakhulu.Akufanele ishintshe esimweni sokulungiswa kweyinki.Uma usebenzisa oyinki abelapheka nge-UV, kufanele kwenziwe imizamo yokugwema ukuchayeka kwesikrini ekukhanyeni kwe-UV nokugwema ukuchayeka elangeni.
Enye inkinga yokulawula uyinki kanye nokulungiswa okungalungile kwesivinini sokuphrinta kungabangela ukuhlinzekwa okungalingani kanye nokomisa ngokushesha kwemeshi eyamukelayo uyinki.
Isizathu sokugcina sokoma kweyinki ukuthi i-squeegee isethwe ngendlela engafanele noma igqoke.Uma uphrinta isithombe esihle esinenombolo ephezulu yemigqa yesikrini, kuyadingeka ukuthi usebenzise umphetho we-squeegee ukuguqula noma ukugqokwa ngesikhathi sokusetshenziswa okuvamile.Ukucija kwesithombe kuncishisiwe, okubonisa ukuthi uyinki kungenzeka ungadluli kuma-mesh ngokujwayelekile.Uma le nkinga ingaxazululwa ngesikhathi, uyinki uzokoma ku-mesh.Ukuze ugweme lezi zinkinga, i-squeegee kufanele iphendulwe ngezikhathi ezithile ukuze kunwetshwe impilo ye-squeegee yaso, noma ukushintshela ku-squeegee entsha ngaphambi kokuba ikhwalithi yokuphrinta yehle.
Ukuze i-mesh isebenze kahle, kufanele kuqashelwe ukukhipha ukungcola kuyinki noma ku-substrate.Ngenxa ye-electrostatic adsorption yezinto ezingcolisayo emoyeni nezimo ezimbi zokugcina, ingaphezulu le-substrate lingase lingcole.Izinkinga ezingenhla zingaxazululwa ngokuthuthukisa izimo zokugcina nokulawula inqubo.Ngaphezu kwalokho, i-destaticizer ne-substrate decontamination device ingasetshenziswa.Vimbela uthuli nokungcola ekudluliseni ukusuka endaweni yokuphrinta kuye kunenetha.
Yini okufanele ngiyenze uma i-stencil ingcolile?Uma usebenzisa iphrinta yesikrini esiyisicaba, misa iphrinta ngemva kokuphrinta isethi yamashidi, bese ufaka iphepha lokusula ukuze uhlanganise isikrini ne-blotter..
Vumela isikrini sibe sesimweni sokuphrinta, bese usula ukungcola endaweni ye-stencil ngendwangu ethambile engancibiliki ngesihlanzi sesikrini.Ungasebenzisi amandla amaningi, ngakho ukungcola kuzowela nge-mesh.Ephepheni elidonsayo elingezansi, uma kunesidingo, phinda ukuhlanzwa kwe-mesh ngesiqephu sephepha elimuncayo.Ezinye zezinhlayiya zokungcola eziwela phezulu zingase zibe zinkulu kakhulu ukuthi zingadlulela emanetheni, kodwa zingananyathiselwa ngendwangu ethambile.Ngemuva kokuhlanza, ithempulethi ingashaywa nge-blower (shayela "umoya obandayo").
Lapho uhlanza iphrinta yesikrini esiyindilinga, kuhlangatshezwana nezimo ezihlukene.Ngenxa yesakhiwo sokuklama, akunakwenzeka ukugeza ukungcola ephepheni lokumunca njengephrinta yesikrini evamile.Ngenhlanhla, ngenxa yesivinini sokuphrinta esisheshayo, mancane amathuba okuthi uyinki uzokoma kumeshi.Uma lokhu kwenzeka, qala ngokumisa umshini wokunyathelisa lapho uphrinta iqembu, bese usebenzisa indwangu ethambile engaqhumi ukuze usebenzise isicoci sesikrini noma sizacile phezulu kwesifanekiso lapho isithombe siphrintwa khona.I-solvent ikhuhla ukungcola kwe-mesh.
Ngezinye izikhathi ukungcola ngaphansi kwesifanekiso kuyasuswa.Kulesi simo, ukungcola kufanele kusulwe ngobumnene ngendwangu ethambile.Ungasebenzisi amandla amaningi.Izindlela ezingenhla zokuhlanza kanye nokuhlanza kufanele zisetshenziswe kaningi enqubweni yokukhiqiza ukuze kwandiswe impilo yesevisi ye-stencil kanye nomshini wokunyathelisa isikrini futhi kuncishiswe izinga le-scrap.
