Mapepala osindikizira amitundu iwiri ndi osavuta komanso ogwirizana, okhudzana ndi utsogoleri.Komabe, kusindikiza kwa mapepala amitundu iwiri kumakhala kolakwika, choncho nkhani zingapo ziyenera kuzindikirika posindikiza mipiringidzo iwiri.
1. yokutidwa pawiri zomatira pepala, chifukwa cha digiri osauka awiri zomatira pepala sizing'ono pa msika, zosavuta kuchotsa tsitsi ndi ufa, kotero posankha inki ayenera kusankha zofewa inki kusindikiza.Inki ndi yovuta, inki yowoneka bwino ndiyosavuta kukoka pamwamba pa ufa wa pepala ndi tsitsi la pepala, zomwe zimapangitsa kuti bulangeti la mphira liwunjike, kusamutsa koyipa, kukhetsa kwa inki, kutsika kwachangu, kutayika kwa pepala, bulangeti labala ndi kusindikiza kwamba. ndi osauka.Kuphatikiza apo, kukakamiza kusindikiza kuyenera kukhala kocheperako, osati kwakukulu.Ndipo mphira bulangeti ayenera kusankha bwino mphira pamwamba, osati zosavuta kuwononga, kupirira bwino kwa bulangeti labala.
2. Mavuto amayamwitsa mapepala omatira pawiri, opanga mapepala ophatikizana awiri okhala ndi mayamwidwe amphamvu a inki, kuyamwa kwamadzi, kotero kusankha kwa inki kuyenera kusankha mtundu wapamwamba kwambiri ndipo kumatha kulowa mu inki youma.Ngati mtundu suli wochuluka, inki wosanjikiza ndi wandiweyani, pepala limatenga madzi ambiri posindikiza, ndipo inki ndi pepala zimauma pang'onopang'ono.Komanso, ngati inki padziko filimu kuyanika mofulumira kwambiri, zingakhudze pansi pa pepala malowedwe kuyanika, chifukwa mu yosindikiza padziko kuyanika, kudula pepala, kumanga ndi njira zina chifukwa cha pepala si youma mkati ndi mavuto ena.
3. Pawiri zomatira pepala PH mtengo, monga PH mtengo wa pawiri zomatira pepala pa msika ndi zambiri asidi ofooka, kotero kusindikiza kunyowetsa njira sangakhale acidic kwambiri, PH mtengo zambiri anapereka pafupifupi 5.5, ndende yaikidwa pa pafupifupi 12-15%, yomwe imathandizira kusindikiza ndi kuyanika.Kuphatikiza apo, pakusindikiza, kuwongolera mwamphamvu kwamadzi, inki yoyambira nthawi yamadzi ndi mulingo wa inki sayenera kukhala wokwera kwambiri.Pankhani ya mbale kusindikiza sangakhoze kupirira zauve, kotunga madzi ndi inki kotunga ayenera kukhala pang'ono ngati n'kotheka kuti mwamsanga kufika bwino inki, madzi ndi inki kukhala zochepa, kusindikiza kukhala zochepa.
Sikoyenera kupachika 150 maukonde, 133 maukonde, nthawi zina 200 mizere yosindikiza zotsatira zabwino.Kuwonjezera pa kupanga makina osindikizira, kutsetsereka kwa mbali ziwiri za pepala kumapangitsanso kusiyana kwakukulu, mbali yoipa ya chithunzi chosindikizidwa ndizovuta kuti ziwoneke ngati zopanda pake.Choncho, yesani kusankha kusalala bwino kwa pepala.Pawiri TACHIMATA opanga mapepala awiri TACHIMATA pepala mtundu kusindikiza mikhalidwe zabwino kwambiri zotsatira: pofuna kuonetsetsa khalidwe la mankhwala osindikizidwa kukwaniritsa zofunika makasitomala, muyenera kulamulira aliyense ulalo.Pawiri TACHIMATA pepala kusindikiza mbale kulamulira khalidwe, kusindikiza, kuonjezera pang'ono kukhudzana kwenikweni, kotero kuti madontho pa mbale kuposa madontho pa filimu ang'onoang'ono ang'onoang'ono kubweza kuchuluka kwa madontho chifukwa cha kukakamizidwa pa kusindikiza.
Pamene kuphika mbale, mbale mu ndondomeko kuzirala kuchokera kuzizira ndiyeno otentha, adzatulutsa lolingana elongation, shrinkage chodabwitsa.Choncho, pofuna kuonetsetsa kulondola kwa overprinting, mu Mipikisano mitundu kusindikiza zambiri si ankalimbikitsa.Chiwerengero cha mbale zowongoka ziyenera kukhala zaluso komanso zolondola, ndikuchepetsa kuchuluka kwa mbale zomwe zakonzedwa kuti zipewe kusindikiza molakwika chifukwa cha elongation yochita kupanga komanso kupindika kwa mbale yosindikizira.Kuwongolera kosindikiza kwa wopanga mapepala okutidwa kawiri: kunyowetsa njira PH mtengo kuwongolera pa 5.5 ~ 6.5.Ngati mtengo wa PH wa yankho lonyowetsa sunayendetsedwe bwino, zingakhudze kuyanika kwa inki ndi kusindikiza.Pamene kusindikiza, okhwima kulamulira masanjidwe a chinyezi, kukhalabe bwino inki ndi inki, kukwaniritsa "yaing'ono inki youma madzi" zabwino kwambiri boma kusindikiza.Kuwongolera kutentha kwa msonkhano ndi chinyezi.
