Iyini i-chromatic aberration?
I-Chromatic aberration ibhekisela emehlukweni wombala. Ekuphileni kwansuku zonke, sivame ukusho ukuthi umehluko wombala ubhekisela entweni yokungahambisani nombala lapho iso lomuntu libheka umkhiqizo. Isibonelo, embonini yokunyathelisa, umehluko wombala phakathi kwezinto eziphrintiwe kanye nesampula evamile enikezwa ikhasimende.
Embonini nakwezohwebo, kubaluleke kakhulu ukuhlola umehluko wombala womkhiqizo ngokunembile. Kodwa-ke, izici eziningi, njengomthombo wokukhanya, i-engeli yokubuka kanye nesimo sombukeli, zingase ziholele kumehluko ekuhlolweni kombala.
01 Ukuxuba imibala
Isixhumanisi sokuphrinta se-tonning siwumongo wokulungiswa komehluko wombala. Ngokuvamile, ochwepheshe abaningi bokunyathelisa bamabhizinisi banaka kuphela isipiliyoni noma imizwa yabo lapho be-toning, okungeyona indinganiso evamile noma ehlanganisiwe. Zihlala kuphela esimweni sokuqala sombala we-toning futhi zikhululekile kakhulu. Ngakolunye uhlangothi, akunawo umthelela ekuthuthukisweni kwe-chromatic aberration, ngakolunye uhlangothi, kunzima ukulungisa i-hue. Okwesithathu, alikho ikhono elifanele ekulolongeni ikhono lokufanisa umbala labasebenzi.
Ngaphambi kwe-toning, ukunakwa okukhethekile kufanele kukhokhwe ukuvimbela ukusetshenziswa kwezinhlelo ze-inki zokunyathelisa ezivela kubakhiqizi abahlukene kusuka ku-toning. Kungcono ukusebenzisa inki yokuphrinta evela kumkhiqizi ofanayo we-toning. Kudingeka ukuthi izisebenzi ze-toning ziqonde ngokugcwele ukuchema kombala we-inki yokunyathelisa ehlukahlukene, okusiza ukulawula inqubo ye-toning. Ngaphambi kwe-toning, uma kusetshenziswa inki yokunyathelisa esele, kuyadingeka ukuthi uqale wenze kucace umbala we-inki yokunyathelisa, uhlole ukuthi ikhadi lokuhlonza likayinki wokunyathelisa linembile yini, kungcono ukusebenzisa i-scraper ye-inki ukukhuhla ukubonwa kwesampula kanye ukuqhathanisa, bese wengeza, ngaphambi kokungeza, isisindo kufanele siqiniswe ukuze silinganise, bese ubhala idatha.
Ngaphezu kwalokho, lapho ulungisa umthunzi weyinki yombala okhethekile, ungasebenzisa futhi indlela yokulinganisa ye-toning. Uma ukhuhla isampula likayinki, kufanele lilingane, futhi kufanele libambe ingemuva elimhlophe, elisiza ukuqhathanisa nesampula elijwayelekile elihlanganisiwe. Uma umbala ufinyelela ngaphezu kuka-90% wesampula evamile ehlanganisiwe, qinisa ukulungiswa kwe-viscosity. Singenza amasampula, bese siwashuna kahle. Kuyafaneleka ukusho ukuthi ohlelweni lwe-toning, ukunakwa okukhethekile kufanele kukhokhwe ekunembeni kwedatha, futhi ukunemba kwesilinganiso se-elekthronikhi kubaluleke kakhulu ekufingqweni kwemingcele yedatha yenqubo. Lapho isilinganiso idatha inki ukunyathelisa iqiniswa, ngokusebenzisa izikhathi eziningana umkhuba kungaba ngokushesha futhi ngokunengqondo toned, kodwa futhi kungagwema nesenzakalo umehluko umbala.
Kungcono ukuhlanganisa ukufanisa uyinki ngokosayizi wenani le-oda, futhi kuhle ukuqedela umsebenzi wokufanisa umbala ngesikhathi esisodwa ukuze uvimbele ukuchezuka kwechromatic okubangelwa ukufana kwemibala eminingana. Inganciphisa ngokunengqondo umehluko wombala kanye nokuvela kukayinki wokuphrinta osele. Lapho uhlola umbala, ngezinye izikhathi ngisho noma umbala ubukeka ufana ngezansi kokukhanya okuvamile, kodwa ubukeke uhlukile kodwa ngaphansi kolunye uhlobo lokukhanya, ngoba lokhu kufanele kukhethe isibani esisebenzisa indinganiso ehlanganisiwe yenza ukubheka umbala noma ukuqhathanisa nombala.
02 Isikhiya sokuphrinta
Umthelela we-scraper yokuphrinta ekuhlukeni kombala uma i-scraper ivame ukuhanjiswa ekukhiqizeni nasekucubungulweni, indawo yokusebenza ye-scraper izoshintshwa, engahambisani nokudluliselwa okujwayelekile nokukhiqizwa kombala koyinki wokuphrinta, kanye nokucindezela i-scraper ayikwazi ukushintshwa ngokuzenzakalelayo.
Ngaphambi kokukhiqiza nokucutshungulwa, kuyadingeka ukulungisa i-Engeli kanye nendawo ngokuya ngesithombe nombhalo womqulu wokuphrinta. Ummese olandelayo kufanele unake ngokukhethekile isenzo esihlanzekile nesibukhali sesandla. I-Angle ye-scraper ngokuvamile iphakathi kuka-50-60 degrees. Ngaphezu kwalokho, ngaphambi kokusika, ukunakwa okukhethekile kufanele kukhokhwe ukuze kuhlolwe ukuthi i-scraper amaphuzu amathathu alinganiselwe, futhi ngeke kube khona uhlobo lwamagagasi kanye nesimo esiphezulu nesiphansi, esibaluleke kakhulu ekuzinzeni kwesigaba sokunyathelisa.
03 Ukulungiswa kwe-viscosity
Ukulungiswa kwe-viscosity kufanele kuqiniswe ngaphambi kokukhiqizwa nokucutshungulwa, futhi kungcono ukukulungisa ngokuvumelana nesivinini somshini esilindelekile. Ngemuva kokuthi i-solvent ingeziwe, umshini uzolandelanisa ngokugcwele ngemva kwemizuzu engu-10 ngaphambi kokuqala ukukhiqiza nokucubungula. Ukuze kusheshiswe imikhiqizo yomshini wokuhlola ukucutshungulwa kokukhiqizwa ukuze kuhlangatshezwane nezinga lokuqwashisa ngekhwalithi, ngalesi sikhathi kungenza ukutholwa kwe-viscosity, njengenani elihlanganisiwe le-viscosity elijwayelekile lalo mkhiqizo, leli nani kufanele lirekhodwe ngokushesha futhi wonke umkhiqizo owodwa ngokuya ngedatha. ukulungisa, kunganciphisa ngokunengqondo ukuchezuka kombala okubangelwa ukushintsha kwe-viscosity. Ukutholwa kwe-viscosity kufanele kunake ngokukhethekile amakhono okubona. Ngokuvamile, u-inki wokuphrinta ebhakedeni likayinki wokuphrinta noma umcengezi woyinki wokuphrinta uwumzimba oyinhloko obonayo. Ngaphambi kokutholwa, cha. 3 inkomishi ye-viscosity kufanele ihlanzwe ukuze kube lula ukutholwa okunembile.
Ekukhiqizeni okuvamile, kunconywa ukuthi i-viscosity yenziwe isampula njalo ngemizuzu engu-20-30. Ukaputeni noma uchwepheshe angakwazi ukulungisa i-viscosity ngokuvumelana noshintsho lwe-viscosity value. Lapho ulungisa i-viscosity ye-inki yokunyathelisa futhi wengeza i-solvent, kufanele kukhokhwe ukunakwa okukhethekile ukuze kungabi nomthelela ngokuqondile ku-inki yokunyathelisa, ukuze kuvinjelwe umonakalo wesistimu ye-inki yokunyathelisa ngaphansi kwezimo ezivamile, ukuhlukaniswa kwe-resin ne-pigment, bese ukuphrinta izinwele zomkhiqizo, ukukhiqizwa kombala akwanele.
04 Imvelo Yokukhiqiza
I-workshop air humidity regulation, ngaphansi kwezimo ezijwayelekile silungisa i-55% -65% ifaneleka kakhulu.
Umswakama ophezulu uzothinta ukunyibilika kukayinki wokuphrinta, ikakhulukazi ukudluliselwa kwendawo enetha engajulile kunzima ukuyibonisa ngokujwayelekile. Ukulungiswa okunengqondo kokuswakama komoya, umphumela wokuphrinta uyinki nokulungiswa kombala kunendima ethuthukisiwe.
05 impahla eluhlaza
Ukuthi ukungezwani okungaphezulu kwempahla eluhlaza kuyafaneleka kuthinta ukumanzisa nokudlulisa umthelela kayinki wokuphrinta ku-substrate, futhi kuphinde kuthinte umphumela wokuboniswa kombala kayinki wokuphrinta kufilimu, futhi kungenye yezinto ezithinta umehluko wombala. . Ukuqinisekisa ikhwalithi yezinto ezingavuthiwe kuyisidingo sokulawula ikhwalithi. Kubaluleke kakhulu ukukhetha abahlinzeki abaqeqeshiwe.
06 Ukuqwashisa Ngekhwalithi
Ukuqwashisa ngekhwalithi kubhekisela embonweni wekhwalithi yomkhiqizo ngokukhiqiza, ukucubungula kanye nabasebenzi bokuphatha ikhwalithi.
Lo mbono kufanele ube sobala, ubonakale emininingwaneni yomsebenzi. Ngakho-ke ekulungiseni umehluko wombala ikakhulukazi ukuqondisa ukuqwashisa kwekhwalithi yabasebenzi ukuze bathuthuke, emsebenzini wobuhle, balolonge umqondo wekhwalithi yomkhiqizo, njengokufakazela ukuhambisana ngokuqinile nesampula evamile efinyelelwe ngaphezu kuka-90%, qala ukukhiqiza nokucutshungulwa, engxenyeni yokuqala ukusiza izisebenzi zokuhlola ikhwalithi ukuze ziqinise ingxenye yokuqala yomsebenzi wokuhlola.
Iqinile nezisebenzi ekukhiqizeni nasekucubunguleni ukusebenza kwesistimu yokuphatha ikhwalithi, njengokushintshwa kombala we-inki wokunyathelisa ekukhiqizeni nasekucubungulweni, ikakhulukazi naka imininingwane yomcengezi kayinki wokunyathelisa, futhi unake ngokukhethekile ekugcineni kwesitezi kanye nalokho kukhuhla. Isiqeshana se-blade kukhona ukushintsha kwesikhathi noma ukuhlanzwa, le mininingwane emincane, uma inganaki ngokukhethekile ekukhiqizeni nasekucubungulweni kungenzeka phakathi kwe-hue yombala oxubile, Imbangela ukuguquguquka kombala, bese kuba nokushintshashintsha kwe-chromatic.
Umbala umehluko ekunyatheliseni akunakugwenywa, indlela yokugwema noma ukunciphisa okwenzeka umehluko umbala, kuyisihluthulelo, ukuhlaziywa okuningiliziwe izici ezihlukahlukene ngenhla, ukuze bakwazi ukuthola amasu ngcono, kungaba eminye ukugwema umehluko umbala, indlela yokulawula umehluko wombala, kuphela ekumisweni komthombo kanye nokuphathwa kwesampula, kunganciphisa futhi kugweme umehluko wombala, Kuphela ngokunaka ngokukhethekile ukuphathwa kokusebenza okuningiliziwe nokucubungula idatha ekukhiqizeni nasekucubungulweni singakwazi ukwenza imikhiqizo engcono futhi sithuthukise ukuncintisana kwemakethe okuphelele kwamabhizinisi.
