Ukuphrinta isikrini kukhiqiza ukuchezuka kombala ngenxa yalezi zici

Kungani ukuphrinta kwesikrini kukhiqiza ama-color cast? Uma sibeka eceleni inhlanganisela yemibala eminingana futhi sicabangele umbala owodwa kuphela, kungase kube lula ukuxoxa ngezimbangela zombala wemibala. Lesi sihloko sabelana ngezinto ezimbalwa ezithinta ukuchezuka kombala ekuphrinteni kwesikrini. Okuqukethwe okwereferensi ngabangane abathenga futhi banikeze isistimu yokupakisha ye-Youpin:

Uhlu olungezansi ezinye zezinto ezivame kakhulu ezidala ukuchezuka kombala ekuphrinteni kwesikrini: ukulungiswa kweyinki, ukukhetha kwemeshi, ukungezwani kwemeshi, ukucindezela, ukomisa, izici ze-substrate, izimo zokubuka, njll.

 

01 Ukulungiswa kukayinki
Ukuxutshwa kukayinki Uma sicabanga ukuthi umbala kayinki osetshenzisiwe ungowombala ojwayelekile, imbangela enkulu yokuchezuka kombala ukwengezwa kwezincibilikisi ezifana nowoyela wokuxuba uyinki kuyinki. Eshabhu elinemishini emihle yokulawula imibala, uyinki ungaxutshwa ngokuya ngemishini yokulawula. Nokho, ezinkampanini eziningi zokunyathelisa, akunakwenzeka ukuba nalezi zakhiwo. Bathembela kuphela kokuhlangenwe nakho kwezisebenzi eziyizingcweti lapho bexuba uyinki.

Ngokuvamile, uwoyela wokulungisa uyinki uyengezwa ukuze wenze uyinki ulungele ukunyatheliswa. Nokho, lapho uwoyela wokulungisa usungeziwe kuyinki, ukugcwala kwezimibalabala kuyinki kuzoshintsha, okuzoholela ekushintsheni ezicini zombala zikayinki phakathi nokunyathelisa. Ngaphezu kwalokho, i-solvent eyeqile kuyinki izokwakha ifilimu encane yeyinki ngemva kokumisa, okuzonciphisa ukukhanya kombala.

Kuphinde kube nenkinga yokuhlanjululwa kukayinki ngaphambi kokufakwa kukayinki. Isibonelo, izisebenzi esitolo sikayinki zenza izinqumo ngokusekelwe kufomula yazo lapho zixuba noma zihlanza uyinki. Lokhu kuholela ekuphambukeni kombala okungenakugwemeka. Uma uyinki uxutshwe ezinsukwini ezimbalwa ezedlule, Uma uphrinta ngoyinki omuhle, umbala owenziwe yilesi simo uzoba sobala kakhulu. Ngakho-ke, cishe akunakwenzeka ukugwema ngokuphelele ukufakwa kombala.

 

02 Ukukhethwa kwemeshi
Uma ucabanga ukuthi usayizi wemeshi wesikrini ukuphela kwento ethinta ukudluliswa kukayinki, uzohlangabezana nenkinga enkulu. Ububanzi bemeshi nemibimbi nakho kuthinta ukudluliselwa kukayinki. Ngokuvamile, uma uyinki eningi enamathiselwe ezimbotsheni zikayinki zesikrini, uyinki omningi uzodluliselwa ku-substrate ngesikhathi senqubo yokuphrinta.

Ukuze ulinganisele kusenesikhathi ukuthi ungakanani uyinki ongadluliswa nge-mesh ngayinye, abahlinzeki abaningi bezikrini bahlinzeka ngevolumu yokudlulisa eyingqikithi yethiyori (TIV) yemeshi ngayinye. I-TIV iyipharamitha ekhombisa usayizi wenani lokudlulisa uyinki esikrinini. Kubhekiselwa enanini likayinki elidluliswayo kokuthi Ungakanani uyinki ozodluliselwa ngemeshi ngayinye ngaphansi kwezimo ezithile zokuphrinta. Iyunithi yayo ingumthamo kayinki endaweni yeyunithi ngayinye.

Ukuqinisekisa amathoni angaguquki ekuphrinteni, akwanele ukugcina inombolo ye-mesh yesikrini ingashintshiwe, kodwa futhi ukuqinisekisa ukuthi ububanzi besikrini kanye nokuguquguquka kwaso kuhlala kungashintshi. Izinguquko kunoma iyiphi ipharamitha yesikrini zizoholela ekushintsheni kobukhulu befilimu kayinki ngesikhathi sokuphrinta, okuholela ekushintsheni kombala.

 

03 Ukushuba kweNet
Uma ukushuba kwenetha kukuncane kakhulu, kuzokwenza ukuthi ifilimu iqhume. Uma kune-inki eningi ehlala enethini, into ephrintiwe izoba ngcolile.

Le nkinga ingaxazululwa ngokwandisa ibanga phakathi kwesikrini ne-substrate. Kodwa-ke, ukukhulisa ibanga phakathi kwesikrini ne-substrate kudinga ukukhulisa ingcindezi, okuzokwenza ukuthi uyinki owengeziwe udluliselwe ku-substrate. ukushintsha ukuminyana kombala. Indlela engcono kakhulu ukugcina ukungezwani kwe-stretch net uniform, ukuze kuqinisekiswe ukuhambisana kombala.

 

04 Izinga lokucindezela
Izilungiselelo zokucindezela ezifanele zibalulekile ekugcineni umbala ongaguquki, futhi nokuqinisekisa amazinga okucindezela afanayo phakathi nenqubo yokuphrinta kubalulekile. Ikakhulukazi emisebenzini yevolumu ephezulu, ephindaphindayo yokuphrinta.

Uma kuziwa ekucindezelweni, into yokuqala okufanele icatshangelwe ubulukhuni be-squeegee. Ukuqina kwe-squeegee kuncane, okulungele izinga lokuxhumana, kodwa akulungile ukumelana nokugoba. Uma ubulukhuni buphezulu kakhulu, ukungqubuzana kwesikrini nakho kuzoba kukhulu ngesikhathi sokuphrinta, ngaleyo ndlela kuthinte ukunemba kokuphrinta. Eyesibili i-angle ye-squeegee kanye nesivinini se-squeegee. I-engeli yommese kayinki inomthelela omkhulu enanini lokudluliswa kwe-inki. Uma i-engeli yommese kayinki incane, likhulu inani lokudluliswa kwe-inki. Uma isivinini sommese we-inki sishesha kakhulu, sizobangela ukugcwaliswa kwe-inki okunganele kanye nokuphrinta okungaphelele, ngaleyo ndlela kuthinte ikhwalithi yokuphrinta.

Uma usuthole izilungiselelo ezilungile zokucindezela komsebenzi wokuphrinta futhi waziqopha ngokunembile, inqobo nje uma ulandela lezi zilungiselelo ngendlela efanele phakathi nenqubo yokuphrinta, uzothola umkhiqizo wokuphrinta owanelisayo onemibala engaguquki.

 

05 womile
Ngezinye izikhathi, umbala ubukeka uvumelana ngemva nje kokunyathelisa, kodwa umbala ushintsha ngemva kokutholakala komkhiqizo ophelile. Lokhu kuvame ukubangelwa izilungiselelo ezingalungile zemishini yokomisa. Isizathu esivame kakhulu ukuthi izinga lokushisa le-dryer libekwe phezulu kakhulu, okwenza umbala we-inki ephepheni noma ekhadibhodi ushintshe.

 

06 Izici ze-substrate
Inkinga eyodwa izingcweti zokuphrinta isikrini ezivame ukungayinaki indawo engaphezulu ye-substrate. Iphepha, amakhadibhodi, ipulasitiki, njll. konke kukhiqizwa ngamaqoqo, futhi ama-substrates ekhwalithi ephezulu angaqinisekisa izakhiwo ezinzile nezingashintshi. Kodwa akunjalo. Izinguquko ezincane ezakhiweni ezingaphezulu ze-substrate zizodala ukuphambuka kombala ekuphrinteni. Ngisho noma ingcindezi yokunyathelisa ifana futhi ngisho nenqubo ngayinye iqhutshwa ngendlela efanele, ukungahambisani kwezakhiwo ezingaphezulu ze-substrate kuzophinde kubangele ukushintsha kombala okukhulu ekuphrinteni. Umbala wokulingisa.

Lapho umkhiqizo ofanayo unyatheliswa kuma-substrates ahlukene ngemishini efanayo yokunyathelisa, ithonya lezakhiwo ezingaphezulu ze-substrate embala libonakala ikakhulukazi. Amakhasimende angase adinge ukuthi izikhangiso zefasitela ziphrintwe epulasitikini noma kwelinye amakhadibhodi. Futhi amaklayenti angase adinge imibala engaguquki esiqeshini esifanayo.

Ezimweni ezinjengalezi, isixazululo kuphela ukwenza izilinganiso zombala ezinembile. Sebenzisa i-spectrophotometer noma i-spectral densitometer ukuze ulinganise ukuminyana kombala. Uma kukhona ukushintsha kombala, i-densitometer ingakubonisa ngokucacile, futhi ungakwazi ukunqoba lokhu kushintsha kombala ngokulawula ezinye izinqubo.

 

07 Izimo zokubhekwa

Amehlo omuntu azwela kakhulu ekushintsheni okucashile kombala, futhi angakwazi ukuhlukanisa imibala ngaphansi kwezimo zokukhanya. Ngenxa yalokhu, qiniseka ukuthi uqhathanisa imibala ngaphansi kwezimo ezifanayo zokukhanyisa. Uma kungenjalo, ukulungisa ivolumu ye-inki noma ukucindezela kuzokhiqiza uyinki owengeziwe. Umbala omkhulu wokulingisa.

Sekukonke, ukhiye wokugcina umbala ongaguquki usekulawuleni okuzinzile kwenqubo ngayinye ukuqinisekisa ukusebenza okuzinzile kukayinki. Ukukhethwa kosayizi wemeshi, ukushuba nokucindezela kwesikrini esinwetshiwe, izici ezingaphezulu ze-substrate nezimo zokubuka konke kunomthelela othile ekuchezukeni kombala. Nokho, amarekhodi esethingi anembe nokulawula okuzinzile kwenqubo ngayinye izikhiye zokuqinisekisa imibala yokuphrinta yesikrini engaguquki.
