Kusintha kwapakati kopepuka: amatanthauza mfundo zingati zomwe zingayikidwa mu inchi imodzi; unit: PDI
Kuchulukitsa kwa Maonekedwe: Kutanthauza kuchuluka kwa tinthu tating'onoting'ono tomwe timatsekedwa, ndiye kuti, kuthekera koletsa kuwala, unit ndi "D = LA>
Gamma: Gama ikunena za kuchuluka kwa zomwe zimapangitsa kuti kagwiridwe kake kasintha kalimidwe mutatha kuwunika?
Ii. Kapangidwe ndi ntchito ya filimu yopepuka
1 pamtunda:
Imagwira nawo gawo popewa kukwapula ndi kuteteza mchere wamchere wosanjikira kuti uwonongeke!

2.drug film (sava ​​wamchere wosanjikiza)
Mu chithunzicho osanjikiza, zigawo zikuluzikulu za emulsion ndi siliva wa siliva, siliva tsabola, siliva ndi utoto womwe umatha kubwezeretsanso malo a siliva pansi pa kuwunika. Koma mchere wa siliva ndi wopanda madzi, motero gelatin amagwiritsidwa ntchito kuti azikhala pamalo oyimitsidwa ndikuwotcha pa filimuyo. Ma pigment mu emulsion amatenga chidwi.
3.. Zomata zomata
Limbikitsani zomatira za emulsion wosanjikiza ku filimuyo. Pofuna kukonza mphamvu yolumikizana pakati pa emulsion ndi filimuyo, yankho la madzi am'madzi ndi chromelume alum imagwiritsidwa ntchito ngati wolumikizana kuti ukhale womangika.
4.. Polyester Base wosanjikiza
Carfier film ndi Stoffiel School Coorser nthawi zambiri amagwiritsa ntchito nitrocellulose, acetate kapena polyester filimu. Mitundu iwiri yoyambirira ya zowonjezera makanema imakhala ndi kusinthasintha kwakukulu, ndipo kukula kwa polyeter filimu ndi kokhazikika
5.. Anti-halo / stack wosanjikiza
Anti-halo ndi magetsi okhazikika. Panthawi yovuta, pansi pamtunda filimuyo imawonetsa kuwala, ndikupangitsa Emulsion wosanjikiza kachiwiri kuti apange Halo. Popewa Halo, njira yothetsera matenda a gelatin kuphatikiza zoyambira fuchsin imagwiritsidwa ntchito kukhoma kumbuyo kwa filimuyo kuti imeke kuwala. Amatchedwa anti-blance wosanjikiza.

Iii, kugwiritsa ntchito makina ojambula owoneka bwino
1.
Utoto wopepuka ndi njira yopepuka. Kanemayo atawululidwa, mchere wa siliva utabweza malo siliva, koma pakadali pano, palibe zithunzi zomwe zitha kuwoneka pa filimuyo, yomwe imatchedwa chithunzi chasintha. Makina owoneka bwino ndi awa: Makina a Laser Laser Love Love, mtundu wamkati wa Laser Spend Shotter, mtundu wakunja wa mbiya laser wopepuka, etc.
2. Kupanga
Mchere wa siliva pambuyo pa zowunikira zimachepetsedwa ndi zigawo zakuda zasiliva. Kutentha kwa wopanga kumathandizira kwambiri liwiro la chitukuko. Kutentha kwambiri, kuthamanga kwa chitukuko cha chitukuko. Kutentha koyenera kumakhala 18 ℃ ~ 25 ℃. Zigawo zikuluzikulu za madzi amthunzi zimapangidwa ndi wopanga, woteteza, wokonza ndege ndi woletsa. Ntchito zake ndi motere:
1) .deverder: Ntchito ya wopanga ndikuchepetsa mchere wa siliva wasiliva. Chifukwa chake, wopanga nawonso amathandiziranso wothandizira. Mankhwala omwe amagwiritsidwa ntchito nthawi zambiri amagwiritsa ntchito mankhwala ochepetsa ma hydroquinone ndi p-cresol sulfate.
2). Mtumiki Woteteza: Wotetezayo amaletsa wopanga zomwe amapanga kuti atuluke, ndipo sodium sulfite nthawi zambiri amagwiritsidwa ntchito ngati wothandizira.
3) .Chilator: Wothandizira ndi mtundu wa alkalinine yemwe ntchito yake ndikuthandizira chitukuko. Omwe amathandizira agalumu ndi a Cruomu Carbonate, borax, sodium hydroxide, etc., omwe sodium hydroxide ndi aluso lamphamvu.
4). Oganti: Ntchito yolephera kuchepetsedwa kuchepetsa mchere wamchere wa usiliva, womwe ungalepheretse gawo lopanda chitukuko cha chitukuko. Potaziyamu Broomide ndi woletsa bwino, ndipo ili ndi malo otetezedwa okhala ndi zolepheretsa, ndipo malo okhala ndi chidwi chofooka ndi amphamvu.

Iv. Kukonza
Gwiritsani ntchito ammonium thiosulpate kutenga mchere wamchere womwe sunachepetse siliva, apo ayi mchere wa siliva udzaululidwanso, kuwononga chithunzi choyambirira.
