Firimu chinhu chakajairika chekubatsira kugadzirwa kwezvinhu mune redunhu board indasitiri.Iyo inonyanya kushandiswa kuchinjisa mifananidzo, solder mask uye zvinyorwa.Unhu hwefirimu hunobata zvakananga kunaka kwechigadzirwa.
Firimu ifirimu, ndiyo shanduro yekare yefirimu, ikozvino inowanzoreva firimu, inogona zvakare kureva iyo yakaipa mundiro yekudhinda.Iyo firimu yakaunzwa munyaya ino inoreva zvakashata mubhodhi redunhu rakadhindwa.
Firimu rose rakasviba, uye nhamba yefirimu chiratidzo cheChirungu.Pakona yefirimu, ratidza kuti firimu nderipi reC, M, Y, kana K, uye imwe yecmyk (kana nhamba yeruvara rwemavara).Inoratidza ruvara rwekubuda kwefirimu.Kana zvisina kudaro, unogona kutarisa pakona yechidzitiro kuti uone ruvara.Iyo yakatsikwa yemavara bar padivi payo inoshandiswa kuita dot density calibration.
Rudzi rwemavara harisi kungoona chete kuti density yedot yakajairika, kana kutarisa CMYK, iyo inowanzotongwa nenzvimbo yebhari yemavara: bhari yeruvara ndeye C mukona yezasi kuruboshwe, bhari yemavara M in. kona yekumusoro kuruboshwe, uye Y ari mukona yekurudyi.Kona yezasi yekurudyi ndiK, chero bedzi fekitari yekudhinda ichiziva CMYK maererano nebhari yemavara.Izvi zvinoreva kuti, kuitira kuti zvive nyore kuongororwa kwehuwandu hwekugadzirwa kwefirimu, kune nhamba dzemavara pamakona efirimu.Kana iri nhamba yemavara achadhindwa, inotarirwa nemutsara wekrini yefirimu imwe neimwe.
Izvo zvakakosha zvemufirimu firimu firimu rinodzivirira, emulsion layer, bonding film, film base uye anti-halation layer.Izvo zvakakosha zvesirivha munyu photosensitive zvinhu, gelatin uye pigments.Sirivha munyu inogona kudzorera sirivheri musimboti wepakati pasi pekuita kwechiedza, asi haina kunyungudika mumvura.Nokudaro, gelatin inogona kushandiswa kuita kuti ive yakasimirirwa mamiriro uye yakaputirwa pachigadziko chefirimu.Iyo emulsion inewo pigment yekukurudzira.Zvadaro firimu yakafumurwa inowanikwa kuburikidza ne actinic action.

Iyo firimu inogona kugadziriswa mushure mekuratidzwa.Zvisizvo zvakasiyana zvine mamiriro akasiyana ekugadzirisa.Usati washandisa, iwe unofanirwa kuverenga mirairo yekushandiswa kweasina kunaka kuti uone iyo chaiyo yekuvandudza uye inogadzirisa magadzirirwo.
Maitiro ekugadzirisa firimu ndeaya anotevera:
Kuratidzwa kwekufungidzira: ndiko kuti, mushure mokunge firimu yaonekwa, munyu wesirivha unodzorera sirivha, asi panguva ino, hapana mifananidzo inogona kuonekwa pafirimu, iyo inonzi latent image.
Development:
yave kuda kuderedza munyu wesirivheri mushure mekuvhenekera kuita zvimedu zvesirivha zvitema.Munguva yekuvandudzwa kwemanyorero, iyo yakafumurwa sirivheri yemunyu firimu inonyudzwa zvakaenzana mugadziriso mhinduro.Nokuti sirivheri yemunyu firimu inoshandiswa mukugadzirwa kwemapuranga akadhindwa ane yakaderera photosensitive speed, nzira yekuvandudza inogona kutariswa pasi pechiedza chekuchengetedza, asi chiedza hachifaniri kunge chakanyanya kujeka , Kuti urege kubuda kunze kwefirimu yakaipa.Kana iyo mifananidzo mitema pamativi ese eiyo yakaipa ine kudzika kwemavara akafanana, kusimudzira kunofanira kumira.
Bvisa firimu kubva mukugadzirisa kugadzirisa, sukurudza nemvura kana asidi yekumisa mhinduro, wozoiisa mukugadzirisa kugadzirisa uye kugadzirisa.Kupisa kwemugadziri ane simba guru pakukurumidza kwekusimudzira.Iyo yakakwirira tembiricha, iyo inokurumidza kukurumidza kukurumidza.Iyo yakanyanya kufanirwa kukura tembiricha ndeye 18 ~ 25OC.
Muchina wekugadzira maitiro unopedzwa otomatiki muchina wekudhirowa, teerera kune huwandu hwehuwandu hwemushonga.Kazhinji, chiyero chekugadzirisa chekugadzirisa mhinduro yekubaya muchina ndeye 1: 4, kureva kuti, gadziriso inogadzirwa ye1 yekuyeresa kapu vhoriyamu inosanganiswa zvakaenzana nemakapu ekuyeresa mana emvura yakachena.
Kugadzirisa:
ndiko kunyungudutsa munyu wesirivha usina kuderedzwa kuita sirivheri pane zvisina kunaka kudzivirira chikamu ichi chemunyu chesirivheri kuti chisakanganisa mufananidzo wakashata mushure mekuratidzwa.Nguva yekunyora firimu-kupedzisa nekugadzirisa inopetwa kaviri mushure mekunge pasina mafotoensitive zvikamu pafirimu zviri pachena.Iyo yekudhirowa uye kugadzirisa maitiro emuchina zvakare inopedzwa otomatiki nemuchina wekudhirowa.Chiyero chekumisikidza chesyrup chinogona kukora zvishoma pane chesirasi inokura, kureva kuti, 1 kapu yekuyeresa yesyrup inosanganiswa zvakaenzana nemakapu ekuyeresa matatu nehafu yemvura.
Washing:
Iyo firimu yakagadziriswa inonamira nemakemikari akadai sodium thiosulfate.Kana isina kusukwa, iyo firimu inoshanduka yero uye isingashande.Mahwendefa anoputirwa nemaoko anowanzoshambidzwa nemvura inoyerera kwemaminitsi 15-20.Iyo yekugezesa nekuomesa maitiro emuchina wekugadzira firimu inopera otomatiki nemuchina wekugadzira firimu.
mhepo yakaoma:
Izvo zvakashata zvakapedzwa nemaoko zvinofanirawo kuchengetwa munzvimbo inotonhorera uye yakaoma mushure mekuoma kwemhepo.
Mukuita kuri pamusoro, chenjerera kuti usakwenya firimu, uye panguva imwe chete, usasasa zvigadziriso zvemakemikari zvakaita sekugadzira uye kugadzirisa mvura pamuviri wemunhu nezvipfeko.
