Ukuphrinta ipuleti lethusi kanye nokuphrinta kwe-offset kuyizindlela ezimbili ezihlukene ezisetshenziswa embonini yokuphrinta. Nakuba zombili lezi zindlela zifeza injongo yokukhiqiza kabusha izithombe ezindaweni ezahlukene, ziyahlukahluka ngokwenqubo, izinto ezisetshenzisiwe, kanye nemiphumela yokugcina. Ukuqonda umehluko phakathi kwalezi zindlela ezimbili kungakusiza ukuthi wenze isinqumo esinolwazi mayelana nokuthi iyiphi inketho efanela izidingo zakho kangcono.
Ukuphrinta ipuleti lethusi, okwaziwa nangokuthi ukuphrinta kwe-intaglio noma ukuqopha, kuyindlela yendabuko ebilokhu isetshenziswa amakhulu eminyaka. Kuhilela ukuqopha isithombe epuletini lethusi ngesandla noma kusetshenziswa ubuchwepheshe besimanje. Ipuleti eliqoshiwe libe selifakwa inki, bese kuthi uyinki owengeziwe ususwe, kushiye isithombe kuphela ezindaweni eziqoshwe phansi. Ipuleti licindezelwa ephepheni elimanzi, bese isithombe sidluliselwa kulo, okuholela ekuphrinteni okucebile nokunemininingwane. Le ndlela ihlonishwa kakhulu ngekhono layo lokukhiqiza ukuphrinta okujulile, okunobunjwa, nobuciko.
Ngakolunye uhlangothi, ukuphrinta kwe-offset kuyindlela yesimanje futhi esetshenziswa kabanzi. Kuhilela ukudluliselwa kwesithombe sisuka epuletini lensimbi siye engubeni yerabha, bese siyiswa ezintweni ezifunwayo, njengephepha noma ikhadibhodi. Isithombe siqala siqoshwe epuletini lensimbi kusetshenziswa inqubo ye-photochemical noma uhlelo lwekhompyutha oluya epuletini. Ipuleti libe selifakwa inki, bese isithombe sidluliselwa engubeni yerabha. Ekugcineni, isithombe siyiswa ezintweni, okuholela ekuphrinteni okunemininingwane eminingi nokunembile. Ukuphrinta kwe-offset kwaziwa ngekhono laso lokukhiqiza inani elikhulu lokuphrinta ngokushesha nangokungabizi kakhulu.
Umehluko omkhulu phakathi kokunyathelisa ipuleti lethusi nokunyathelisa kwe-offset usezintweni ezisetshenziswayo. Ukunyathelisa ipuleti lethusi kudinga ukusetshenziswa kwamapuleti ethusi, aqoshwe futhi aqoshwe ngesandla. Le nqubo idinga isikhathi, ikhono, kanye nobuchwepheshe. Ngakolunye uhlangothi, ukunyathelisa kwe-offset kuncike kumapuleti ensimbi, angakhiqizwa kusetshenziswa ubuchwepheshe obuthuthukisiwe kanye nezinqubo ezenzakalelayo. Lokhu kwenza ukunyathelisa kwe-offset kube ukukhetha okufinyeleleka kalula futhi okungabizi kakhulu kokukhiqizwa ngobuningi.
Omunye umehluko obalulekile uhlobo lwesithombe olukhiqizwa yindlela ngayinye. Ukuphrinta ipuleti lethusi kuhamba phambili ekudaleni ukuphrinta okuyinkimbinkimbi nobuciko okunezindinganiso ezicebile zethoni kanye nokuthungwa okujulile. Ngokuvamile kuyathandwa ezincwadini eziphezulu, ukuphrinta kobuciko obuhle, kanye nokuphrinta okulinganiselwe. Ukuphrinta kwe-offset, ngakolunye uhlangothi, kunikeza ukukopisha okunembile, okugqamile, nokungaguquguquki okufanelekela ukuphrinta kwezentengiselwano, njengezincwajana, amaphosta, nomagazini.
Ngokuphathelene nezindleko, ukuphrinta ipuleti lerabha kungonga izindleko, okulungele inani elincane kanye nezidingo zokuphrinta eziphansi; Izindleko zokuphrinta ipuleti lethusi ziphezulu, kodwa umphumela wokuphrinta uphelele, futhi kufanelekile ezidingweni zombala nephethini zokuphrinta.
Ekuphetheni, ukuphrinta ipuleti lethusi kanye nokuphrinta kwe-offset kuyizindlela ezimbili ezihlukile ezisetshenziswa embonini yokuphrinta, ngayinye inezinzuzo zayo. Ukuphrinta ipuleti lethusi kuyahlonishwa ngobuciko bayo kanye nekhono lokudala ukuphrinta okunemininingwane, okunobuthi. Ngakolunye uhlangothi, ukuphrinta kwe-offset kunikeza ukuphrinta okusheshayo, okungabizi kakhulu, kanye nekhwalithi ephezulu okufanele ukukhiqizwa ngobuningi. Ngokuqonda umehluko phakathi kwalezi zindlela, ungenza isinqumo esinolwazi mayelana nokuthi iyiphi indlela efanelana kahle nezidingo zakho zokuphrinta.
