I-Takeaway: isikrini sikasilika njengokwakhiwa kwezinto zokupakisha izimonyo zivame kakhulu inqubo yokuphrinta yezithombe, ngokusebenzisa inhlanganisela kayinki wokunyathelisa, isikrini sokunyathelisa isikrini, imishini yokunyathelisa isikrini, yenza inki ngesithombe engxenyeni ye-mesh idluliselwe kuma-substrates, kule nqubo, ukushintsha kombala wokuphrinta kwesikrini kuzothonywa ezinye izici, leli phepha labelana ngezinto ezimbalwa ezithinta ukuguqulwa kombala wokuphrinta, okuqukethwe kwereferensi yabangane:
UsilikaSukreniPukukhala
Inqubo yokuphrinta isikrini iyinki ngengxenye yesikrini ngemuva kokuvuza ku-substrate, sonke isikrini sesikrini sivinjiwe, uyinki awukwazi ukudlula.Uyinki wokuphrinta athululelwe esikrinini, ngaphandle kwamandla angaphandle ngaphansi kwesenzo sikayinki ngeke avuze esikrinini kuya ku-substrate, futhi lapho isikreyi esinokucindezela okuthile futhi sitshekisa uyinki wokukhuhla i-Angle, uzodluliselwa ku-substrate elandelayo ngokusebenzisa isikrini ukuze kuzuzwe ukuphindaphinda kwesithombe.
01 uyinkiMixing
Ngokucabanga ukuthi i-pigment kuyinki isetshenziswe kahle, khona-ke, isizathu esivamile sokushintsha umbala ukungezwa kwe-solvent.Endaweni yokusebenzela elawulwa kahle, inki kufanele itholakale kumaphephandaba uma isilungile, okungukuthi, iphrinta akufanele ixube uyinki.Ezinkampanini eziningi, u-inki awulungiselelwa umshini wokunyathelisa, kodwa ushiyelwa kumshicileli, owengeza futhi axube uyinki ngokubona kwakhe.Ngale ndlela, ibhalansi ye-pigment kuyinki iphukile.Ngoyinki ojwayelekile osuselwe emanzini noma uyinki we-UV, amanzi akuyinki ngendlela efanayo nencibilikisi ku-inki we-solvent, ukwengeza amanzi kuzokwenza ifilimu ye-inki eyomile ibe mncane, futhi kuthinte umbala weyinki, bese kuncishiswa ukuminyana. lombala.Izimbangela zezinkinga ezinjalo zingalandelelwa ngokuqhubekayo.
Endaweni yokugcina uyinki, izisebenzi ezihambisana noyinki azisebenzisi izinto zokukala, zithembele kuphela ekwahluleleni kwazo ukuze zengeze inani elifanele le-solvent, noma ekuqaleni kokuxuba akulungile, noma ekunyatheliseni inani lokuxuba uyinki, ukuthi uyinki oxubile uzoveza imibala ehlukene.Lapho ucezu olubukhoma luphrintwa futhi kamuva, isimo siba sibi kakhulu, futhi cishe akunakwenzeka ukukhiqiza kabusha umbala ngaphandle kokuthi kuqoshwe isilinganiso esanele sikayinki.
02 Ukukhethwa Kwesikrini
Ububanzi bemeshi yocingo nendlela yokweluka, okuyithafa noma i-twill, ukujiya kwefilimu kayinki wokuphrinta kunomthelela omkhulu.Abahlinzeki besikrini bazohlinzeka ngesikrini esinemininingwane yolwazi lobuchwepheshe, okungenye yevolumu yeyinki ebaluleke kakhulu, imelela inani likayinki ngemeshi ngaphansi kwezimo ezithile zokuphrinta, ngokuvamile ezivezwa yi-CM3 /m2.Isibonelo, isikrini esingu-150 mesh/cm esinobubanzi bemeshi obungu-31μm sizodlula ku-11cm3/m2 kayinki.Ububanzi besikrini obungu-34μm, isikrini semeshi esingu-150, imitha yesikwele ngayinye sizodlula ku-6cm3 kayinki, okulingana no-11 no-6μm wogqinsi lukayinki owugqinsi.Kuyabonakala ukuthi i-150 mesh lesi sithombe esilula, sizokwenza ukuthi uthole ukujiya kwengqimba yeyinki ehluke kakhulu, umphumela uzodala umehluko omkhulu ngombala.
Ngokuthuthukiswa kobuchwepheshe bokuluka isikrini, ukuthola inombolo ethile yesikrini se-twill kunesikrini esingenalutho, nakuba ngezinye izikhathi kungenzeka, kodwa kungenzeka kuncane kakhulu.Kwesinye isikhathi abahlinzeki besikrini bagcina isikrini esidala se-twill, ngokuvamile, ivolumu ye-inki yethiyori yalezi zikrini inoshintsho olungu-10%.Uma usebenzisa ukuphrinta kwesikrini esilukiweyo se-twill sezinga elihle lesithombe, isimo sokuphuka komugqa ocolekile kungaphezu kokusebenzisa isikrini esingenalutho.
03 IsikriniVinguqulo yeTumfutho
Ukushuba okuphansi kwesikrini kuzoholela ekuhlukaniseni kancane kwesikrini endaweni ephrintiwe, okuzothinta uyinki ehlala esikrinini, kanye nomthelela wombala ongalingani, ukuze umbala ubonakale ushintsha.Ukuze uxazulule le nkinga, kuyadingeka ukwandisa ibanga lesikrini, okungukuthi, ukwandisa ibanga phakathi kwepuleti lesikrini esivundlile kanye nezinto zokuphrinta.Ukwandisa ibanga eliphelele kusho ukukhulisa ukucindezela kwe-scraper, okuzothinta inani likayinki esikrinini, okuholela ekushintsheni okuqhubekayo kombala.
04 Ukusetha kweScraper
Uma i-scraper isetshenziswa, uzodlula uyinki esikrinini.Ukucindezela okukhulu ku-scraper, ekuphrinteni, ukugqokwa kwe-scraper blade kuzoba ngokushesha, okuzoshintsha indawo yokuxhumana ye-scraper kanye nokuphrinta, okuzophinde kuguqule inani likayinki esikrinini, okuholela ekushintsheni kombala.Shintsha i-engeli yokukhuhla uyinki kuzophinde kuthinte inani lokunamathela kukayinki.Uma i-scraper igijima ngokushesha kakhulu, lokhu kuzonciphisa ukushuba kongqimba lweyinki olunamathiselwe.
05 Back kweInk KnifeSetting
Umsebenzi wommese oyinki ukwenza imbobo yesikrini igcwaliswe ngenani elizinzile likayinki.Ukulungisa ingcindezi, I-engeli kanye nobukhali bommese kayinki kuzokwenza imbobo yenethi ibe mkhulu kakhulu noma uyinki omncane kakhulu.Ukucindezela kommese kayinki wangemuva kukhulu kakhulu, kuzophoqelela uyinki ku-mesh, okuholela ekunamathiselwe kweyinki kakhulu.Ukucindezelwa kommese oyinki akwanele, kuzodala inkinki egcwele ingxenye kuphela, okuholela ekunamathiselwe kwi-inki okunganele.Ijubane lokugijima lommese we-inki nalo libaluleke kakhulu.Uma igijima kancane kakhulu, uyinki uzochichima.Uma igijima ngokushesha kakhulu, izodala ukuntula kukayinki okunzima, okufana nomphumela wokushintsha isivinini se-scraper.
06 umshini Setting
Ukulawula inqubo ngokucophelela kuyisici esibucayi kakhulu.Ukulungiswa okuzinzile nokungaguquki komshini kusho umbala ozinzile futhi ongaguquki.Uma ukulungiswa komshini kushintshashintsha, umbala ungaphuma ekulawuleni.Le nkinga ivame ukwenzeka lapho iphrinta ishintsha amashifu, noma kamuva lapho iphrinta ishintsha Izilungiselelo emshinini ukuze zivumelane nemikhuba yakhe, engabangela ukushintsha kombala.Ukucindezela kwakamuva kwesikrini se-multicolor kuqeda lokhu kungenzeka ngokulawula ikhompuyutha okuzenzakalelayo.Lezi zinguquko ezizinzile, ezingaguquguquki kufanele zenziwe emshinini wokunyathelisa futhi kufanele zigcinwe kuwo wonke umsebenzi wokunyathelisa.
07 Ukuphrinta Mizinto zokwakha
Isici esivame ukunganakwa semboni yokuphrinta isikrini ukuhambisana kwe-substrate material ezophrintwa.Iphepha, amakhadibhodi kanye nepulasitiki okusetshenziselwa ukuphrinta ngokuvamile kukhiqizwa ngamaqoqo.Umhlinzeki wekhwalithi ephezulu angaqinisekisa ukushelela okuhle kwendawo yalo lonke iqoqo lezinto ezinikeziwe, kodwa lokhu akunjalo ngaso sonke isikhathi, futhi noma yiluphi ushintsho oluncane enqubweni lungashintsha umbala nokuqedwa kwendawo yalezi zinto.Uma lokhu sekwenzekile, umbala wokuphrinta ubonakala ushintsha, nakuba kungekho lutho olushintshile phakathi nenqubo yokuphrinta.
Lezi yizinkinga ezingokoqobo amaphrinta ahlangabezana nazo lapho akhangisa isithombe esisodwa ezintweni ezihlukahlukene, kusukela kupulasitiki kathayela kuya ebhodini lobuciko elihle.Enye inkinga esivame ukuhlangana nayo ukuthi ukuphrinta kwesikrini kwethu ukuze sibambe izithombe zokuphrinta ze-offset, uma singakunaki ukulawula inqubo, asinalo ithuba.Ukulawula inqubo ngokucophelela kuhilela ukunqunywa kombala okunembile, ukunqunywa kombala womugqa nge-spectrophotometer, nokunqunywa kombala oyinhloko nge-densitometer, ukuze sikwazi ukuphrinta izithombe ezinemibala ezinzile nengaguquguquki ezintweni ezihlukahlukene.
08 LubusukuSwethu
Ngaphansi kwemithombo yokukhanya ehlukene, imibala ibonakala ihlukile, futhi iso lomuntu lizwela kakhulu kulezi zinguquko.Lo mphumela ungancishiswa ngokuqinisekisa ukuthi umbala osetshenziselwa ukuhlanganisa oyinki ufana nse nombala ofanayo phakathi nomsebenzi wokunyathelisa.Lokhu kungaba inhlekelele uma ushintsha abahlinzeki.Ukunqunywa kombala kanye nokubona kuyindawo eyinkimbinkimbi kakhulu, futhi ukuze ulawuleke kahle kufanele kube neluphu evaliwe yomkhiqizi we-inki, ukusabalalisa, ukufakazela kanye nokuzimisela okunembile phakathi nenqubo yokuphrinta.
09 Dry
Ngezinye izikhathi umbala ushintsha ngenxa yokulungiswa okungalungile kwesomisi.Iphepha lokuphrinta noma amakhadibhodi, uma izinga lokushisa lokumisa liphezulu kakhulu, isimo esivamile simhlophe phuzi.Imboni yengilazi neye-ceramics ikhathazwa kakhulu ukushintsha kombala ngesikhathi somiswa noma sokubhaka.Izibala zombala ezisetshenziswa lapha ziyashintsha ukusuka kokuphrintiwe ukuya kwe-sintered.Umbala walezi zinhlayiya awuthinteki nje kuphela izinga lokushisa lokubhaka, kodwa futhi nge-oxidation noma ukwehla kwekhwalithi yomoya endaweni yokubhaka.
