Ukuprinta ipleyiti yekopolo kunye nokuprinta i-offset ziindlela ezimbini ezahlukeneyo ezisetyenziswa kwishishini lokuprinta. Nangona zombini ezi ndlela zisebenza ngenjongo yokuphinda imifanekiso kwiindawo ezahlukeneyo, zahlukile ngokwenkqubo, izixhobo ezisetyenzisiweyo, kunye neziphumo zokugqibela. Ukuqonda umahluko phakathi kwezi ndlela zimbini kunokukunceda wenze isigqibo esinolwazi malunga nokuba loluphi ukhetho olufanela iimfuno zakho.
Ukuprinta ipleyiti yobhedu, okwaziwa ngokuba kukuprinta kwe-intaglio okanye ukukrola, yindlela yendabuko esetyenziswe kangangeenkulungwane. Kubandakanya ukukrola umfanekiso kwipleyiti yobhedu ngesandla okanye kusetyenziswa ubuchwepheshe banamhlanje. Emva koko ipleyiti eqoshiweyo iyafakwa i-inki, kwaye i-inki egqithisileyo iyasuswa, kushiyeke umfanekiso kuphela kwiindawo ezikroliweyo. Ipleyiti icinezelwa ephepheni elimanzi, kwaye umfanekiso udluliselwa kuyo, nto leyo ephumela kushicilelo olutyebileyo noluneenkcukacha. Le ndlela ixatyiswa kakhulu ngenxa yokukwazi kwayo ukuvelisa iiprinti ezinzulu, ezithambileyo, nezobugcisa.
Kwelinye icala, ukuprinta nge-offset yindlela yanamhlanje nesetyenziswa kakhulu. Ibandakanya ukudluliselwa komfanekiso ukusuka kwipleyiti yesinyithi ukuya kwingubo yerabha, uze uye kwizinto ezifunwayo, njengephepha okanye ikhadibhodi. Umfanekiso uqala ukrolwe kwipleyiti yesinyithi kusetyenziswa inkqubo ye-photochemical okanye inkqubo yekhompyutha ukuya kwipleyiti. Emva koko ipleyiti ifakwa i-inki, kwaye umfanekiso udluliselwa kwingubo yerabha. Ekugqibeleni, umfanekiso ufakwa kwimpahla, nto leyo ebangela ushicilelo oluneenkcukacha ezininzi noluchanekileyo. Ukuprinta nge-offset kwaziwa ngokukwazi kwayo ukuvelisa inani elikhulu leeprinti ngokukhawuleza nangendlela engabizi kakhulu.
Umahluko ophambili phakathi kokuprinta ipleyiti yobhedu kunye nokuprinta i-offset usezintweni ezisetyenziswayo. Ukuprinta ipleyiti yobhedu kufuna ukusetyenziswa kweepleyiti zobhedu, ezikrolwa kwaye ziqoshwe ngesandla. Le nkqubo ifuna ixesha, ubuchule, kunye nobuchule. Kwelinye icala, ukuprinta i-offset kuxhomekeke kwiipleyiti zesinyithi, ezinokuveliswa kusetyenziswa ubuchwepheshe obuphambili kunye neenkqubo ezizenzekelayo. Oku kwenza ukuprinta i-offset kube lukhetho olufikelelekayo nolungabizi kakhulu kwimveliso yobuninzi.
Omnye umahluko obalulekileyo luhlobo lomfanekiso oluveliswa yindlela nganye. Ukuprinta ipleyiti yobhedu kuyagqwesa ekudaleni iiprinti ezintsonkothileyo nezinobugcisa ezinexabiso elikhulu lethoni kunye noburhabaxa obunzulu. Kudla ngokuthandwa kwiimpapasho eziphezulu, iiprinti zobugcisa obuhle, kunye neeprinti zohlelo olulinganiselweyo. Kwelinye icala, ukuprinta kwe-offset kunika iikopi ezichanekileyo, ezikhanyayo, nezihambelanayo ezifanelekileyo zokuprinta kwezorhwebo, njengeencwadana, iipowusta, kunye neemagazini.
Ngokuphathelele iindleko, ukuprinta ipleyiti yerabha kunokonga iindleko, nto leyo efanelekileyo kwiimfuno ezincinci zokuprinta; Ixabiso lokuprinta ipleyiti yobhedu liphezulu, kodwa isiphumo sokuprinta sigqibelele, kwaye sifanelekile kwiimfuno zombala kunye neepateni zokuprinta.
Ukuqukumbela, ukuprinta ipleyiti yekopolo kunye nokuprinta i-offset ziindlela ezimbini ezahlukeneyo ezisetyenziswa kushishino lokuprinta, nganye ineempawu zayo. Ukuprinta ipleyiti yekopolo kuhlonitshwa ngobuchule bayo kunye nokukwazi kwayo ukwenza iiprinta ezineenkcukacha, ezithungwe ngendlela ethile. Kwelinye icala, ukuprinta i-offset kunika iiprinta ezikhawulezayo, ezingabizi kakhulu, nezisemgangathweni ophezulu ezifanelekileyo kwimveliso enkulu. Ngokuqonda umahluko phakathi kwezi ndlela, ungenza isigqibo esinolwazi malunga nokuba loluphi uhlobo lwendlela olufanele iimfuno zakho zokuprinta.
