Chosindikizira chosindikizira ndi gawo lofunikira pakusamutsa chithunzi ku gawo lapansi monga pepala kapena nsalu. Amagwiritsidwa ntchito m'njira zosiyanasiyana zosindikizira, kuphatikizapo offset, flexographic ndi gravure printing. Mtundu uliwonse wambale yosindikiziraali ndi makhalidwe apadera ndipo ndi oyenera kusindikiza ntchito zinazake. M'nkhaniyi, tiwona mitundu itatu ikuluikulu ya zosindikiza ndi momwe amagwiritsidwira ntchito.
Ma mbale osindikizira a Offset amagwiritsidwa ntchito kwambiri posindikiza malonda chifukwa cha kutulutsa kwawo kwapamwamba komanso kusinthasintha. Ma mbale awa nthawi zambiri amapangidwa ndi aluminiyamu kapena poliyesitala ndipo amakutidwa ndi emulsion ya photosensitive. Chithunzi chomwe chiyenera kusindikizidwa chimasamutsidwa ku mbale yosindikizira pogwiritsa ntchito njira yojambula zithunzi zomwe madera osakhala azithunzi amatengedwa kuti ndi madzi otsekemera ndipo madera azithunzi amatengedwa kuti ndi inki.
Pali mitundu iwiri ikuluikulu ya mbale zosindikizira za offset: mbale zachikhalidwe zosindikizira za analogi ndi mbale zamakono zosindikizira za digito. Traditional analogi mbale kusindikiza amafuna osiyana fano zoipa, amene ntchito kuvumbula mbale. Kumbali inayi, mbale za digito zimatha kujambulidwa mwachindunji pogwiritsa ntchito teknoloji ya kompyuta-to-plate (CTP), kuchotsa kufunikira kwa filimu, kupangitsa kuti ntchitoyi ikhale yabwino.

mbale zolimba zapakatikati, zokometsedwa kuti zisindikizidwe za mapangidwe omwe amaphatikiza ma halftones ndi zolimba mu mbale imodzi. Zabwino kwa magawo onse omwe amayamwa komanso osayamwa omwe amagwiritsidwa ntchito nthawi zambiri (ie pulasitiki ndi zojambulazo za aluminiyamu, matabwa okutidwa ndi osakutidwa, liner yosindikiza). kupindula kwadontho kochepa mu halftone.Wide exposure latitude ndi kuya kwabwino kwampumulo.Zoyenera kugwiritsidwa ntchito ndi inki zosindikizira zamadzi ndi mowa.
Ma mbale osindikizira a Offset amadziwika chifukwa cha luso lawo lopanga zithunzi zowoneka bwino komanso mwatsatanetsatane, zomwe zimawapangitsa kukhala oyenera kusindikiza monga magazini, timabuku ndi kulongedza. Amaperekanso mwayi wosintha mbale mwachangu komanso mosavuta, zomwe zimapangitsa kuti ntchito zisinthe mwachangu.
Flexographic printing plate, Flexographic printing, kapena flexographic printing, ndi chisankho chodziwika bwino chosindikizira pazigawo zosinthika monga pulasitiki, mapepala, ndi makatoni. Ma mbale osindikizira a Flexographic nthawi zambiri amapangidwa ndi mphira kapena zinthu za photopolymer ndipo amayikidwa pa odzigudubuza kuti asindikize. Ma mbalewa amapangidwa kuti asamutsire inki ku gawo lapansi pogwiritsa ntchito mpumulo wosinthika womwe umagwirizana ndi mizere ya malo osindikizira.
Ma mbale a Photopolymer ndi omwe amagwiritsidwa ntchito kwambiri ndi mbale zosindikizira za flexographic. Amapangidwa powonetsa zinthu za photopolymer kudzera mu kuwala kwa UV, komwe kumaumitsa madera azithunzi ndikusiya malo omwe sali zithunzizo kukhala ofewa komanso otha kutsuka. Njirayi imathandizira kuberekanso kolondola komanso kosasintha kwa zithunzi, kupanga mbale za photopolymer kukhala zabwino zosindikizira zolemba, kulongedza ndi zotengera zamalata.
Ma mbale osindikizira a Flexographic amadziwika kuti amatha kugwira ntchito zosiyanasiyana za inki ndi ma substrates, zomwe zimawapangitsa kukhala oyenera ntchito zosiyanasiyana m'makampani opanga ma CD ndi zilembo. Amaperekanso mphamvu zosindikizira zothamanga kwambiri, zomwe zimawapangitsa kukhala okwera mtengo kusankha kusindikiza kwapamwamba.
Gravure printing plate, Gravure printing, yomwe imadziwikanso kuti gravure printing, ndi njira yosindikizira yapamwamba kwambiri yomwe imagwiritsidwa ntchito popanga magazini, ma catalogs, ndi zisindikizo zokongoletsa. Ma mbale osindikizira a gravure amapangidwa ndi chitsulo chamkuwa kapena chromed ndipo amakhala ndi ma cell otsekeka kapena mabowo omwe amakhala ndi inki. Chithunzicho chimakhazikika kapena chojambulidwa pa mbale pogwiritsa ntchito mankhwala kapena makina, kupanga mapangidwe a maselo omwe amagwirizana ndi chithunzi chomwe mukufuna.
Mitundu iwiri ikuluikulu ya mbale zosindikizira za gravure ndi silinda ndi flatbed. Ma cylinder mbale amakulungidwa mozungulira silinda ndipo amagwiritsidwa ntchito posindikiza mosalekeza, pomwe mbale zathyathyathya zimagwiritsidwa ntchito pakuthamanga kwakufupi komanso ntchito zapadera. Ma mbale osindikizira a Gravure amatha kupanga tsatanetsatane wabwino komanso ma toni osiyanasiyana, kuwapangitsa kukhala oyenera kupanga zithunzi zapamwamba kwambiri.
Mapepala osindikizira a Gravure amadziwika chifukwa cha kukhazikika kwawo komanso kusindikiza kwautali, zomwe zimawapangitsa kukhala oyamba kusankha ntchito zosindikizira kwambiri. Amathanso kusindikiza pazigawo zosiyanasiyana, kuphatikizapo mapepala, pulasitiki ndi zitsulo, zomwe zimawapanga kukhala oyenera kusindikiza ntchito zosiyanasiyana.
Mwachidule, mbale zosindikizira zimagwira ntchito yofunika kwambiri pamakampani osindikizira, ndipo kumvetsa mitundu yosiyanasiyana ya mbale zosindikizira n’kofunika kwambiri posankha njira yoyenera yochitira ntchito inayake yosindikizira. Kaya mbale zosindikizira za offset zosindikizira malonda apamwamba kwambiri, flexographic printing plates for flexible packaging, kapena gravurembale zosindikizirakwa mabuku apamwamba, mtundu uliwonse wa mbale yosindikizira umapereka ubwino wapadera ndi Ntchito. Posankha mbale yoyenera yosindikizira, osindikiza amatha kukwaniritsa khalidwe la kusindikiza ndi luso lomwe amafunikira pazosowa zawo zosindikizira.
