Kudhinda neplate yemhangura uye kudhinda neoffset inzira mbiri dzakasiyana dzinoshandiswa muindasitiri yekudhinda. Kunyange zvazvo nzira dzese dziri mbiri dzichishanda pakuburitsa mifananidzo panzvimbo dzakasiyana-siyana, dzakasiyana maererano nemaitiro, zvinhu zvakashandiswa, uye mhedzisiro yekupedzisira. Kunzwisisa mutsauko uripo pakati penzira mbiri idzi kunogona kukubatsira kuita sarudzo ine ruzivo nezvekuti ndeipi sarudzo inonyatsokodzera zvaunoda.
Kudhinda plate yemhangura, inozivikanwawo sekudhinda kana kunyora muintaglio, inzira yechinyakare yagara ichishandiswa kwemazana emakore. Inosanganisira kudhinda mufananidzo paplate yemhangura nemaoko kana kushandisa tekinoroji yemazuva ano. plate yakavezwa inobva yadhindwa neinki, uye inki yakawandisa inobviswa, zvichisiya mufananidzo uri mugomba rakachekwa chete. plate yacho inodzvanywa papepa rakanyoroveswa, uye mufananidzo unotamisirwa pairi, zvichikonzera kudhindwa kwakapfuma uye kwakadzama. Nzira iyi inoremekedzwa zvikuru nekukwanisa kwayo kugadzira kudhindwa kwakadzika, kwakagadzirwa, uye kwehunyanzvi.
Kune rumwe rutivi, kudhinda kweoffset inzira yemazuva ano uye inoshandiswa zvakanyanya. Inosanganisira kutamisa mufananidzo kubva mundiro yesimbi kuenda mugumbeze rerabha, wozoenda pazvinhu zvinodiwa, zvakaita sepepa kana kadhibhodhi. Mufananidzo unotanga wacherwa pandiro yesimbi uchishandisa nzira ye photochemical kana system yecomputer-to-plate. Ndiro yacho inobva yaiswa ingi, uye mufananidzo wacho unotamisirwa pandiro yerabha. Pakupedzisira, mufananidzo wacho unoiswa pandiro, zvichiita kuti pave nekudhindwa kwakanyatsotsanangurwa uye kwakarurama. Kudhinda kweoffset kunozivikanwa nekukwanisa kwayo kugadzira maprints akawanda nekukurumidza uye nenzira isingadhuri.
Musiyano mukuru pakati pekudhinda maplate emhangura nekudhinda kweoffset uri muzvinhu zvinoshandiswa. Kudhinda maplate emhangura kunoda kushandiswa kwemaplate emhangura, ayo anotemwa uye anonyorwa nemaoko. Maitiro aya anoda nguva, hunyanzvi, uye hunyanzvi. Kune rumwe rutivi, kudhinda kweoffset kunoshandisa maplate esimbi, ayo anogona kugadzirwa uchishandisa matekinoroji epamusoro uye maitiro ega. Izvi zvinoita kuti kudhinda kweoffset kuve sarudzo iri nyore uye isingadhuri yekugadzira zvinhu zvakawanda.
Mumwe musiyano mukuru ndewerudzi rwemufananidzo unoburitswa nenzira imwe neimwe. Kudhinda kwemhangura kunoyevedza pakugadzira madhindindi akaomarara uye ehunyanzvi ane hunhu hwakapfuma uye magadzirirwo akadzika. Kazhinji inofarirwa kudhindwa kwepamusoro-soro, madhindindi eunyanzvi hwakanaka, uye madhindindi akaganhurirwa. Kudhinda kweoffset, kune rumwe rutivi, kunopa makopi akajeka, ane simba, uye akafanana akakodzera kudhinda kwekutengeserana, senge mabhurocha, maposta, nemagazini.
Panyaya yemutengo, kudhinda rabha kunogona kuchengetedza mari, izvo zvakakodzera kudhinda kushoma uye kwakaderera; Mutengo wekudhinda copper plate wakakwira, asi mhedzisiro yekudhinda yakakwana, uye yakakodzera kudhinda mavara uye mapati zvinodiwa.
Mukupedzisa, kudhinda maplate emhangura nekudhinda kweoffset inzira mbiri dzakasiyana dzinoshandiswa muindasitiri yekudhinda, imwe neimwe ine zvayakanakira. Kudhinda maplate emhangura kunoremekedzwa nekuda kwehunyanzvi hwayo uye kugona kwayo kugadzira maprinti akadzama uye ane magadzirirwo. Kudhinda kweoffset, kune rumwe rutivi, kunopa maprinti anokurumidza, asingadhuri, uye emhando yepamusoro akakodzera kugadzirwa kwevanhu vakawanda. Nekunzwisisa mutsauko uripo pakati penzira idzi, unogona kuita sarudzo ine ruzivo nezvekuti ndeipi nzira inonyatsokodzera zvaunoda pakudhinda.
