Namuhla sikhuluma ngombala wezikhwama.Amanye amakhasimende akhathazekile ngokuthi umbala wezikhwama awuwona awulindele.Ngakho kungani kukhona umehluko embala wezikhwama?
Eyodwa, inani likayinki kokungahambisani
Yilokho i-viscosity ehlukene kayinki ethangini likayinki lomshini wokunyathelisa ngezikhathi ezihlukene, ubukhulu benani likayinki kuyinki liyahlukahluka.Kuyo yonke inqubo gravure ukuphrinta, ukugcina ukuzinza isihlobo kanye ukungaguquguquki viscosity uyinki.Qaphela ukuthi i-viscosity ye-inki iyashintsha, evame ukuthinteka ngokushintsha kwezinga lokushisa endaweni yokunyathelisa.
Okwesibili, ukukhethwa kombala we-inki umehluko
Ukuxazulula inkinga yokuhluka kombala we-inki ye-gravure kufilimu yepulasitiki, kufanele sisebenzise ikhwalithi ezinzile, umbala ngokuphambuka noma ukuphambuka kweyinki encane ye-gravure.Ukunyathelisa okuhlukahlukene, kungcono ukulungisa ukusetshenziswa kweyinki yomkhiqizi, inqwaba yezinto eziphrintiwe, kungcono ukusebenzisa umenzi ofanayo, i-batch efanayo yeyinki ekhiqizwa.
Okwesithathu, umjikelezo weyinki awusheleli
Ukuze unake ukugcina ukujikeleza kwe-inki bushelelezi, kungcono kakhulu ukusebenzisa uhlelo lokujikeleza kwe-inki, ukuqinisekisa ukuthi kulula ukungeza umncane futhi wengeze uyinki omusha, ukugcina uyinki unekhwalithi enhle kanye ne-fluidity.
Okwesine, isivinini sokuphrinta nesivinini sokumisa uyinki asihambisani ngaphambi nangemuva
Isivinini sokuphrinta nesivinini sokumisa uyinki, sithinta ngqo izinga le-inki ekuphrintiwe, ngakho-ke isivinini sokuphrinta nesivinini sokumisa uyinki siyashintsha, kuzodala izinguquko kumbala we-inki ekuphrintiwe.
Okwesihlanu, ukusetshenziswa okungafanele kwe-squeegee
Ukuma kwe-scraper, i-engeli ye-scraper, ingcindezi ye-scraper kanye nokucindezela kwesilinda esibonakalayo kumbala we-inki, ikakhulukazi umbala wengxenye engashoni kayinki unomthelela omkhulu.
Okwesithupha, inqubo eyinhlanganisela ihlukile
Ubuchwepheshe obuhlukene bokucubungula okuyinhlanganisela, ukufakwa uphawu kokushisa kwe-welding yokwenziwa kwezikhwama, ukusetshenziswa kwemibala ehlukene yenhlanganisela yefilimu yolwelwesi oluhlanganisiwe, noma ukuphrinta ngokuqondile ngemva kwenqubo ye-vacuum aluminizing, umbala wokuphrinta nawo unomthelela othile.
Ungakhathazeki, imboni yethu inamaqhinga amangalisayo okulungisa umbala wokupakisha.
Qaphela ngokucophelela isampula lombala, qaphela ngokukhethekile ukubheka ingxenye engaphansi ephrintiwe, kusukela ku-substrate emagebhugebhu kanye nezinga elibushelelezi elikhanyayo lokukhethwa kukayinki.
Isibonelo: ukuphrinta kukayinki epuletini noma amakani e-aluminium abushelelezi futhi abonisa kakhulu, khetha izinga eliphezulu lokubonisa ngale kukayinki kuzosiza kakhulu ukuthuthukisa ukucwebezela kwensimbi kayinki.
Uma ukhetha uyinki odingekayo ekuxubeni imibala, gwema ukuhlanganisa uyinki omningi ngangokunokwenzeka.
Zama ukusebenzisa oyinki abaseduze nombala ojwayelekile futhi abenziwe nge-pigment eyodwa.Uma usebenzisa igwebu elinemibala eminingi, lapho uqhelelene nombala ojwayelekile, ukukhanya kuzoba kubi kakhulu.Ukuxuba idigri ye-matte yombala iphakeme, akunakwenzeka ukulungisa umbala wangempela ngokuxuba umbala.Ngakho-ke kuthiwa uma uhlanganisa umbala ungasebenzisa okubili okuxubile, hhayi okuthathu, okuncane okungcono kakhulu.
Ukuze unake ngokukhethekile amandla ombala ayinki.
Uma ukuhlushwa kweyinki ekhethiwe kungaphakeme ngokwanele, kungakhathaliseki ukuthi kupela kanjani, kodwa futhi ayikwazi ukufinyelela ekugxilweni kombala okujwayelekile.
Lapho need ukwengeza uyinki omhlophe nomnyama, kufanele sinake okukhethekile lemali wanezela kanye nokunemba nesisindo.
Kuzo zonke izinhlobo zikayinki, uyinki omhlophe unamandla okuvala aqinile.Uma kungeziwe kakhulu, ngeke nje kunciphise umbala, kodwa futhi kuvimbele i-substrate ekuboniseni.Kodwa-ke, ukuphrinta kuma-substrates angalingani njengendwangu ye-nylon nekhadibhodi, kungcono ukuphrinta ungqimba olumhlophe njengombala wesisekelo ukuze uqinisekise ukubukeka komkhiqizo ophrintiwe.Njengoba amandla ombala we-inki emnyama enamandla kakhulu, uma ungaqapheli ukuthi ungeze kakhulu, uzodinga ukungeza inki eminingi yombala ukuze ulungise umbala futhi ubangele imfucuza, ngakho-ke kufanele kukhokhwe ukunakwa okukhethekile.
Uma wenza uyinki onombala okhanyayo,thinakufanele ihlulele kusukela kuzinga lokudluliswa kokukhanya kwefilimu kayinki, ukuthi ungakanani uyinki omhlophe noma uyinki we-toning okufanele wengezwe ukulungisa umbala.
Akuvunyelwe neze ukusebenzisa i-solvent (encane) ngombala okhanyayo.I-solvent yengezwe kakhulu, ngeke nje ithinte ukusebenza kokunyathelisa, kodwa futhi izolimaza isakhiwo sikayinki, okuholela ekuhlukaniseni ama-pigments namafutha e-resin.Ukubonakala kwemvula noma kunciphisa kakhulu ukucwebezela nokukhanya kukayinki.
Imboni yethu izothumela umdwebo oklanyelwe ikhasimende ngokuvumelana nemfuneko yekhasimende ngaphambi kokuba siqale ukukhiqizwa kwezikhwama.Uma ufuna ukwazi okwengeziwe noma wenze ngezifiso izikhwama zokupakisha ungaxhumana nathi.Sizokunikeza isevisi enhle kanye nentengo evumayo.
