Ifilimu iyinto ejwayelekile kakhulu yokukhiqiza eyisiza embonini yebhodi lesifunda.Isetshenziselwa ikakhulukazi ukudlulisa ihluzo, imaski ye-solder nombhalo.Izinga lefilimu lithinta ngqo ikhwalithi yomkhiqizo.
Ifilimu iyifilimu, iyinguqulo yakudala yefilimu, manje evame ukusho ifilimu, ingaphinde ibhekisele kokubi epuleti lokuphrinta.Ifilimu eyethulwe kulesi sihloko ibhekisela ezintweni ezingezinhle ebhodini lesifunda eliphrintiwe.
Ifilimu imnyama yonke, futhi inombolo yefilimu iwuphawu lwesiNgisi.Ekhoneni lefilimu, khombisa ukuthi iyiphi ifilimu ku-C, M, Y, noma K, futhi ingenye ye-cmyk (noma inombolo yombala wamabala).Ibonisa umbala wokuphuma kwefilimu.Uma kungenjalo, ungabheka i-engeli yesikrini ukuze ubone umbala.Ibha yombala enezitebhisi eduze kwayo isetshenziselwa ukulinganisa ukuminyana kwamachashazi.
Ibha yombala ayikona nje ukubona ukuthi ukuminyana kwamachashazi kujwayelekile yini, noma ukubuka i-CMYK, ngokuvamile ehlulelwa ngokuma kwebha yombala: ibha yombala ingu-C ekhoneni elingezansi kwesokunxele, ibha yombala ithi M in. ekhoneni eliphezulu kwesokunxele, futhi u-Y usekhoneni eliphezulu kwesokudla.Ikhona elingezansi kwesokudla ngu-K, inqobo nje uma imboni yokunyathelisa yazi i-CMYK ngokwebha yombala.Okusho ukuthi, ukuze kube lula ukuhlolwa kokugxila kokuthuthukiswa kwefilimu, kunezinombolo zombala emakhoneni efilimu.Ngokuqondene nenani lemibala ezonyatheliswa, kunqunywa umugqa weskrini wefilimu ngayinye.
Izingxenye eziyinhloko zefilimu yefilimu yifilimu evikelayo, isendlalelo se-emulsion, ifilimu yokubopha, isisekelo sefilimu kanye nesendlalelo sokulwa ne-halation.Izingxenye eziyinhloko yizinsimbi zesiliva zikasawoti ezizwelayo, i-gelatin nezingulube.Usawoti wesiliva ungabuyisela isikhungo somgogodla wesiliva ngaphansi kwesenzo sokukhanya, kodwa awuncibiliki emanzini.Ngakho-ke, i-gelatin ingasetshenziselwa ukuyenza ibe yisimo esimisiwe futhi ihlanganiswe nesisekelo sefilimu.I-emulsion iqukethe nezingulube zokuzwela.Khona-ke ifilimu eveziwe itholakala ngesenzo se-actinic.
Inqubo yokuhlanza ifilimu yebhodi lesifunda
Ifilimu ingacutshungulwa ngemuva kokuchayeka.Okungalungile okuhlukile kunezimo zokucubungula ezihlukene.Ngaphambi kokusetshenziswa, kufanele ufunde imiyalelo yokusebenzisa ama-negative ngokucophelela ukuze unqume ukwakheka okulungile konjiniyela kanye nesilungisi.
Inqubo yokucubungula ifilimu imi kanje:
I-imaging yokuvezwa: okungukuthi, ngemva kokuba ifilimu ivezwe, usawoti wesiliva ubuyisela isikhungo sesiliva, kodwa ngalesi sikhathi, akukho zithombe ezingabonwa kwifilimu, ebizwa ngokuthi isithombe esicashile.
Ukuthuthukiswa:
imayelana nokunciphisa usawoti wesiliva ngemva kokushiswa kwemisebe ube yizinhlayiya zesiliva ezimnyama.Ngesikhathi sokuthuthukiswa kwezandla, ifilimu kasawoti yesiliva eveziwe igxiliswa ngokulinganayo kusixazululo sonjiniyela.Ngenxa yokuthi ifilimu kasawoti yesiliva esetshenziselwa ukukhiqizwa kwamabhodi aphrintiwe inejubane eliphansi le-photosensitive, inqubo yokuthuthukiswa ingabhekwa ngaphansi kokukhanya kokuphepha, kodwa ukukhanya akufanele kukhanye kakhulu , Ukuze ugweme ukuphuma kwefilimu engalungile.Uma izithombe ezimnyama kuzo zombili izinhlangothi zenegethivu zinokujula kombala okufanayo, ukuthuthukiswa kufanele kume.
Khipha ifilimu esixazululweni esikhulayo, hlambulula ngamanzi noma ngesisombululo sokumisa i-asidi, bese uyifaka kwisisombululo sokulungisa bese uyilungisa.Izinga lokushisa lonjiniyela linethonya elikhulu esivinini sokuthuthukiswa.Uma izinga lokushisa liphakeme, isivinini sokuthuthuka sishesha.Izinga lokushisa elifanele kakhulu elikhulayo liyi-18 ~ 25OC.
Inqubo yokuthuthukisa umshini iqedwa ngokuzenzakalelayo ngomshini wokuthwebula othomathikhi, naka isilinganiso sokuhlushwa somuthi.Imvamisa, isilinganiso sokuhlushwa sesixazululo esikhulayo sokushaywa ngomshini singu-1:4, okungukuthi, isisombululo esikhulayo sevolumu yenkomishi yokulinganisa engu-1 sihlanganiswa ngokulinganayo nezinkomishi zokulinganisa ezingu-4 zamanzi ahlanzekile.
Ukulungisa:
ukuncibilikisa usawoti oyisiliva ongakancishiswa ube yisiliva ku-negative ukuvimbela le ngxenye yosawoti wesiliva ukuthi ithinte isithombe esibi ngemva kokuchayeka.Isikhathi sokuqedwa kwefilimu ngesandla nokulungiswa siphindwe kabili ngemva kokuba zingekho izingxenye ezizwela izithombe zefilimu ezibonisa ngale.Inqubo yokuqopha nokulungisa yomshini nayo igcwaliswa ngokuzenzakalelayo ngomshini wokuthwebula othomathikhi.Isilinganiso sokuhlushwa isiraphu singashuba kancane kunesiraphu esakhulayo, okungukuthi, inkomishi yokulinganisa engu-1 yesiraphu yokulungisa ihlanganiswa ngokulinganayo nezinkomishi zokulinganisa ezingu-3 nohhafu wamanzi.
Ukugeza:
Ifilimu ehleliwe inamathele kumakhemikhali afana ne-sodium thiosulfate.Uma ingakashazwa, ifilimu izoba phuzi futhi ingavumelekile.Amaphilisi ashaywa ngesandla ngokuvamile ahlanjululwa ngamanzi agijimayo imizuzu engu-15-20.Inqubo yokugeza kanye nokomisa yokucubungula ifilimu yomshini igcwaliswa ngokuzenzakalelayo ngomshini wokucubungula ifilimu othomathikhi.
umoya owomile:
Ama-negatives aqedwe ngesandla kufanele futhi agcinwe endaweni epholile futhi eyomile ngemva kokumiswa komoya.
Kule nqubo engenhla, qaphela ukuthi ungayinwayi ifilimu, futhi ngesikhathi esifanayo, ungachithi izixazululo zamakhemikhali ezifana nokuthuthukisa nokulungisa uketshezi emzimbeni womuntu nasezimpahleni.
