Ke, masingene kwiinkcukacha kwaye sijonge ilizwe loomatshini bokushicilela beoffset.

Ukuzivelela koomatshini boShicilelo be-Offset

Oomatshini bokushicilela be-Offset banembali ende nenomdla esukela emva ekupheleni kwenkulungwane ye-19. Iindlela zokuqala zokushicilela, njengeletterpress nelithography, zazinemida eliqela. Ezi ndlela zazifuna uhlobo lokwenene okanye umfanekiso ukuze udibane ngqo nezinto eziprintwayo, nto leyo ephumela kwiinkqubo ezitya ixesha namandla alinganiselweyo okushicilela.

Olu tshintsho lweza ngokuyilwa kokushicilela ngeoffset, nto leyo eyabangela ukuba kubekho umntu ophakathi kule nkqubo. Esikhundleni sohlobo okanye umfanekiso ochaphazela ngokuthe ngqo izinto eziphathekayo, zidluliselwe kuqala kwi-rubber blanket kwaye emva koko kwi-substrate yokugqibela. Le mpumelelo ivumele isantya soshicilelo esikhawulezayo, ukuphuculwa komgangatho, kunye nokukwazi ukuprinta kwizinto ezahlukeneyo.

Ukuqonda iNkqubo yoShicilelo ye-Offset

Ushicilelo lwe-Offset lubandakanya inkqubo entsonkothileyo efuna ukuchaneka nokucwangciswa ngononophelo kwamacandelo ahlukeneyo. Ukuyenza lula, masicazulule amanyathelo aphambili abandakanyekayo kwinkqubo yoshicilelo lwe-offset:

ULungiselelo lweMifanekiso kunye nokwenza iipleyiti: Ushicilelo lwe-Offset luqala ngokulungiselela imifanekiso efunekayo. Le mifanekiso inokuthi yenziwe ngokwedijithali okanye ngeendlela zemveli ezifana nokufota. Emva kokuba imifanekiso ilungile, iipleyiti zentsimbi zenziwe ngenkqubo ebizwa ngokuba yi-platemaking. La macwecwe aphethe imifanekiso kwaye abalulekile kwinkqubo yoshicilelo.

Ukufakela Iinki Iipleyiti: Emva kokuba iipleyiti zenziwe, zibotshelelwa kumatshini wokushicilela weoffset. I-ink isetyenziswe kwiiplate, ezinamathele kuphela kwiindawo zemifanekiso. Iindawo ezingeyiyo imifanekiso zihlanganiswe nefilimu encinci yesisombululo sokudambisa amanzi, ukugcina i-inki-repellent.

Ukutshintshela umfanekiso kwi-Blanket: Njengoko iipleyiti ze-inki zijikeleza, zidibana nengubo yerabha. Ingubo idlulisela umfanekiso ukusuka kwiipleyiti ukuya kuwo ngokwawo. Olu tshintshelo lwenzeka ngenxa yomahluko kwiipropati phakathi kwe-inki kunye nesisombululo sokudambisa.

Ukutshintshelwa koMfanekiso kwi-Substrate: Ngoku ukuba umfanekiso uphezu kwengubo, isinyathelo esilandelayo kukudlulisa kwi-substrate yokugqibela. Njengoko i-substrate idlula kumatshini wokushicilela we-offset, idibana nengubo, kwaye umfanekiso udluliselwa kuyo. Le nkqubo inokubandakanya amanyathelo ongezelelweyo afana nokumisa okanye ukuvanisha, kuxhomekeke kwiimfuno.

Ukugqiba: Emva kokuba umfanekiso udluliselwe kwi-substrate, inkqubo yokushicilela igqityiwe. Nangona kunjalo, amanyathelo okugqiba awongezelelweyo afana nokusika, ukusonga, ukubopha, okanye ukucheba kunokufuneka, kuxhomekeke kwimveliso yokugqibela efunekayo.

Izinto eziluncedo kuShicilelo lwe-Offset

Oomatshini bokushicilela be-Offset baqhubeka bebambelele kushishino lokushicilela ngenxa yeenzuzo ezininzi abazinikelayo. Nazi ezinye iingenelo eziphambili zokusebenzisa ushicilelo lweoffset:
