一,
Ƙwarewar aikin fesa fenti na kwalban gilashi
1. Yi amfani da ruwa mai tsafta ko mai tacewa don daidaita fenti zuwa ga ɗanɗano mai dacewa don fesawa. Danɗano mai dacewa gabaɗaya yana ɗaukar daƙiƙa 18 zuwa 30 kamar yadda aka auna ta hanyar na'urar aunawa ta Tu-4. Idan babu na'urar aunawa na ɗan lokaci, ana iya amfani da hanyar gani: a juya fenti da sanda (ƙarfe ko sandar katako) a ɗaga shi zuwa tsayin santimita 20 don dakatar da lura. Ya yi kauri sosai; idan layin ya karye da zarar ya bar gefen sama na ganga, ya yi siriri sosai; idan ya tsaya a tsayin santimita 20, ruwan fenti zai samar da layi madaidaiciya, kuma kwararar za ta tsaya nan take ta zama ɗigon ruwa. Wannan danɗano ya fi dacewa.
2. Ana iya sarrafa matsin iska a 0.3-0.4 MPa (3-4 kgf/cm2). Idan matsin ya yi ƙasa sosai, ruwan fenti ba zai yi atom sosai ba, kuma za a samar da rami a saman; idan matsin ya yi yawa, zai yi laushi cikin sauƙi, kuma hazo na fenti zai yi girma sosai, wanda ba wai kawai zai ɓata kayan ba, har ma zai shafi lafiyar mai aiki.
3. Tazarar da ke tsakanin bututun ƙarfe da saman abu gabaɗaya tana da milimita 200-300. Kusa sosai, yana da sauƙin yin lanƙwasa; nesa da yawa, hazo mai fenti ba shi da daidaito kuma yana iya yin ramuka, kuma hazo mai fenti yana warwatse a kan hanya daga bututun ƙarfe nesa da saman abu, wanda ke haifar da ɓarna. Ya kamata a daidaita takamaiman girman tazara yadda ya kamatabisa ga nau'in fenti na kwalbar gilashi, danko da matsin iska. Lokacin fesa fenti mai busarwa a hankali zai iya zama mafi nisa, lokacin da danko ya yi siriri, zai iya zama mafi nisa; lokacin da matsin iska ya yi yawa, tazara na iya zama mafi nisa, kuma matsin na iya zama ƙarami lokacin da matsin ya yi ƙarami; Idan ya wuce wannan kewayon, zai zama da wahala a sami fim ɗin fenti mai kyau.
4. Ana iya motsa bindigar feshi sama da ƙasa, hagu da dama, zai fi kyau a yi saurin mita 10-12 a minti ɗaya, kuma bututun feshi ya kamata a fesa shi a saman abin don rage feshi mai lanƙwasa. Lokacin fesawa a ƙarshen abu biyu, ya kamata a sassauta hannun da ke jan abin da ke jawo bindigar feshi da sauri don rage hazo mai fenti. Domin ƙarshen abu biyu sau da yawa ana buƙatar fesawa fiye da sau biyu, shine wurin da zai iya haifar da lanƙwasa.
5. Lokacin fesawa, ya kamata a matse hanyar wucewa ta gaba da kashi 1/3 ko 1/4 na hanyar wucewa ta baya, don kada a sami zubewar fesawa. Lokacin fesa fenti mai busarwa da sauri, a fesa shi a jere a lokaci guda. Tasirin fesawar bai dace ba.
6. Lokacin fesawa a waje a bude, a kula da alkiblar iska (kada a yi aiki idan iskar tana da ƙarfi), kuma mai aiki ya kamata ya tsaya a alkiblar iska don hana hazo da iska ke hura shi zuwa fim ɗin fenti da aka fesa kuma ya haifar da mummunan saman.
7. Tsarin fesawa yana da wahala: da farko yana da wahala sannan mai sauƙi, da farko a ciki sannan a waje. Da farko yana da tsayi, sannan ƙasa, da farko ƙaramin yanki sannan babban yanki. Ta wannan hanyar, hazo mai fesawa ba zai fantsama kan fim ɗin fenti da aka fesa ba kuma ya lalata fim ɗin fenti da aka fesa.

Kwarewar daidaita launi na fenti na kwalban gilashi
1. Babban ƙa'idar ladabi
ja + rawaya = lemu
ja + shuɗi = shunayya
rawaya + shunayya = kore
2. Ka'idar asali ta launuka masu dacewa
Ja da kore suna ƙarawa juna ƙarfi, wato, ja na iya rage kore, kuma kore na iya rage ja;
Rawaya da shunayya suna ƙarawa juna ƙarfi, wato rawaya na iya rage shunayya, shunayya kuma na iya rage rawaya;
Shuɗi yana da alaƙa da lemu, wato, shuɗi yana iya rage lemu, kuma lemu yana iya rage shuɗi;
3. Tushen launi
Mutane da yawa suna cewa launi ya kasu kashi uku: launi, haske da kuma cikakken launi. Ana kuma kiran launi da launi, wato, ja, lemu, rawaya, kore, cyan, shuɗi, shunayya, da sauransu; haske kuma ana kiran haske, wanda ke bayyana haske da duhun launi; cikakken launi kuma ana kiransa chroma,wanda ke bayyana zurfin launi.
4. Ka'idojin asali na daidaita launi
Gabaɗaya kada a yi amfani da fenti mai launuka fiye da uku. Ana iya samun launuka daban-daban na tsaka-tsaki (wato, launuka masu launuka daban-daban) ta hanyar haɗa launukan ja, rawaya, da shuɗi a wani rabo. Dangane da launin farko, ƙara fari, za ku iya samun launuka masu cikewa daban-daban (wato, launuka masu launuka daban-daban). Dangane da launin farko, ƙara baƙi, za ku iya samun launuka masu haske daban-daban (wato, launuka masu haske daban-daban).
5. Ƙwarewar daidaitawar launi ta asali
Haɗawa da daidaita launuka na fenti suna bin ƙa'idar launi mai ragi, manyan launuka uku sune ja, rawaya, da shuɗi, kuma launukan haɗin gwiwar su sune kore, shunayya, da orange. Abin da ake kira launukan haɗin gwiwa launuka biyu ne da aka haɗa a wani rabo don samun haske fari, launin haɗin gwiwar ja kore ne, launin haɗin gwiwar rawaya shunayya ne, kuma launin haɗin gwiwar shuɗi orange ne. Wato, idan launin ya yi ja sosai, za ku iya ƙara kore; idan ya yi rawaya sosai, za ku iya ƙara shunayya; idan ya yi shuɗi sosai, za ku iya ƙara lemu. Manyan launuka uku sune ja, rawaya, da shuɗi, kuma launukan haɗin gwiwar su sune kore, shunayya, da lemu. Abin da ake kira launukan haɗin gwiwa launuka biyu ne da aka haɗa a wani rabo don samun haske fari, launin haɗin gwiwar ja kore ne, launin haɗin gwiwar rawaya shunayya ne, kuma launin haɗin gwiwar shuɗi orange ne. Wato, idan launin ya yi ja sosai, za ku iya ƙara kore; idan ya yi rawaya sosai, za ku iya ƙara shunayya; idan ya yi shuɗi sosai, za ku iya ƙara lemu.
Kafin a daidaita launi, da farko a tantance inda launin da za a haɗa yake a cikin hoton bisa ga hoton da ke ƙasa, sannan a zaɓi launuka biyu masu kama da juna don haɗawa a wani rabo. Yi amfani da kayan farantin kwalban gilashi ɗaya ko kayan aikin da za a fesa don daidaita launi (kauri na substrate, kwalban gilashin gishirin sodium da kwalban gilashin gishirin calcium za su nuna tasirin daban-daban). Lokacin haɗa launi, da farko a ƙara babban launi, sannan a yi amfani da launin mai ƙarfi na canza launi a matsayin mataimaki, a hankali a ƙara shi a lokaci-lokaci kuma a ci gaba da juyawa, don lura da canjin launi a kowane lokaci, kuma a ɗauki samfur ta hanyar gogewa, gogewa, fesawa ko manna shi a kan samfurin tsabta. Bayan an daidaita launin, a kwatanta launin da samfurin asali. A cikin dukkan tsarin daidaita launi, dole ne a fahimci ƙa'idar "daga zurfi zuwa duhu".
