I. itheminology
Ukulungiswa komdwebo okhanyayo: kubhekisela ekutheni mangaki amaphuzu angabekwa ubude obuyi-intshi eyodwa; iyunithi: PDI
Ukuminyana kokubona: kubhekisela enanini lezinhlayiya zesiliva ezincishisiwe kufilimu ye-emulsion, okungukuthi, ikhono lokuvimba ukukhanya, iyunithi ithi “D”, ifomula: D=lg (isigameko samandla okukhanya/amandla okukhanya adlulisiwe)
I-Gamma: I-Gamma ibhekisela ezingeni lapho ukuminyana kokubona kwefilimu engemihle kushintsha ngemva kokuba ngaphansi kokukhanya okuhlukile?
II. Ukwakheka kanye nomsebenzi wefilimu yokudweba elula
1 isendlalelo esiphezulu:
Idlala indima ekuvimbeleni imihuzuko futhi ivikele ungqimba lwe-emulsion kasawoti osiliva ukuthi lungonakali!

2.Ifilimu yezidakamizwa (ungqimba we-emulsion kasawoti wesiliva)
Kusendlalelo sesithombe, izingxenye eziyinhloko ze-emulsion ziyi-bromide yesiliva, i-chloride yesiliva, i-iodide yesiliva nezinye izinto ze-photosensitive zikasawoti wesiliva, kanye ne-gelatin nezingulube ezingabuyisela isikhungo esiyinhloko sesiliva ngaphansi kwesenzo sokukhanya. Kodwa usawoti wesiliva awuncibiliki emanzini, ngakho-ke i-gelatin isetshenziselwa ukwenza isimo esimisiwe futhi simbozwe kusisekelo sefilimu. I-pigment ku-emulsion idlala umphumela othokozisayo.
3. Isendlalelo sokunamathisela
Thuthukisa ukunamathela kwesendlalelo se-emulsion kusisekelo sefilimu. Ukuze kuthuthukiswe amandla okubopha phakathi kwe-emulsion nesisekelo sefilimu, isixazululo esinamanzi se-gelatin ne-chrome alum sisetshenziswa njengesendlalelo sokubopha ukuze sihlanganiswe ngokuqinile.
4. Isendlalelo sesisekelo se-polyester
Isisekelo sefilimu yenkampani yenethiwekhi kanye nesisekelo sefilimu esingesihle ngokuvamile sisebenzisa isisekelo sefilimu i-nitrocellulose, i-acetate noma i-polyester. Izinhlobo ezimbili zokuqala zezisekelo zefilimu zinokuguquguquka okukhulu, futhi usayizi wesisekelo sefilimu ye-polyester uzinzile
5. Anti-halo/static layer
I-Anti-halo kanye nogesi omile. Ngaphansi kwezimo ezijwayelekile, indawo engaphansi yesisekelo sefilimu yezithombe izobonisa ukukhanya, kwenze ungqimba lwe-emulsion luzwakale futhi ukuze lukhiqize i-halo. Ukuze uvimbele i-halo, isixazululo esinamanzi se-gelatin kanye ne-fuchsin eyisisekelo sisetshenziselwa ukumboza ngemuva kwesisekelo sefilimu ukuze kuthathwe ukukhanya. Ibizwa nge-anti-halation layer.

III, inqubo yokusebenza yefilimu yokudweba ukukhanya
1. Umdwebo okhanyayo
Ukudweba ukukhanya empeleni kuyinqubo yokukhanya. Ngemva kokuvezwa kwefilimu, usawoti wesiliva ubuyisela isikhungo sesiliva, kodwa ngalesi sikhathi, azikho ihluzo ezingabonwa kwifilimu, ebizwa ngokuthi isithombe esicashile. Imishini yokukhanya esetshenziswa ngokuvamile yilena: imishini yokudweba ukukhanya kwe-laser flat-panel, i-Inner barrel type laser light plotter, i-outer barrel type laser light plotter, njll.
2. ukuthuthukisa
Usawoti wesiliva emva kokukhanyisa uyancipha ube yizinhlayiya zesiliva ezimnyama. Izinga lokushisa lonjiniyela linethonya elikhulu esivinini sokuthuthukiswa. Uma izinga lokushisa liphakeme, isivinini sokuthuthuka sishesha. Izinga lokushisa elifanele elikhulayo ngu-18℃～25℃. Izingxenye eziyinhloko zoketshezi lwesithunzi zenziwe ngonjiniyela, isivikelo, i-accelerator kanye ne-inhibitor. Imisebenzi yayo imi kanje:
1).Umthuthukisi: Umsebenzi womthuthukisi ukunciphisa usawoti oyisiliva ozwela ukukhanya ube yisiliva.Ngakho-ke, umthuthukisi naye uyi-ejenti enciphisayo. Amakhemikhali avame ukusetshenziswa njengama-ejenti okunciphisa afaka i-hydroquinone ne-p-cresol sulfate.
2). I-ejenti evikelayo: I-ejenti evikelayo ivimbela umthuthukisi ekuhlanganiseni i-oxidizing, futhi i-sodium sulfite ivame ukusetshenziswa njenge-ejenti evikelayo.
3).I-Accelerator: I-Accelerator into ene-alkali umsebenzi wayo uwukusheshisa ukuthuthukiswa. Ama-accelerator asetshenziswa kakhulu yi-sodium carbonate, i-borax, i-sodium hydroxide, njll., i-sodium hydroxide iyi-accelerator eqinile.
4). I-inhibitor: Indima ye-inhibitor ukuvimbela ukuncipha kukasawoti wesiliva okhanyayo ube yisiliva, okungavimbela ingxenye engakhanyisiwe ekukhiqizeni inkungu ngesikhathi sokuthuthukiswa. I-Potassium bromide iyisivimbeli esihle, futhi inokuzwela okunamandla kwezithombe

IV. Ukulungisa
Sebenzisa i-ammonium thiosulfate ukuze ususe usawoti wesiliva ongakancishiswa ube yisiliva, ngaphandle kwalokho le ngxenye yosawoti wesiliva izophinde ivezwe, ibhubhise isithombe sokuqala.
