Ukuprinta i-offset kunye nokuprinta isilika ziindlela ezimbini ezidumileyo zokuprinta ezisetyenziswa kwiindawo ezahlukeneyo, kuquka iipayipi. Nangona zisebenza injongo efanayo yokudlulisela uyilo kwiipayipi, kukho umahluko omkhulu phakathi kwezi nkqubo zimbini.
Ukuprinta kwe-offset, okwaziwa ngokuba yi-lithography okanye i-offset lithography, yindlela yokuprinta equka ukudlulisa i-inki kwipleyiti yokuprinta iye kwingubo yerabha, ize emva koko iqengqele i-inki phezu komphezulu wepayipi. Le nkqubo ibandakanya amanyathelo amaninzi, kuquka ukulungiselela umsebenzi wobugcisa, ukwenza ipleyiti yokuprinta, ukufaka i-inki kwipleyiti, kunye nokudlulisela umfanekiso kwipayipi.
Enye yezona nzuzo ziphambili zokuprinta nge-offset kukukwazi kwayo ukuvelisa imifanekiso ekumgangatho ophezulu, eneenkcukacha, nebukhali kwiipayipi. Oku kwenza ukuba ibe lukhetho oludumileyo lokuprinta ngokuchanekileyo njengeelogo, umbhalo, okanye uyilo oluntsonkothileyo. Ukongeza, ukuprinta nge-offset kuvumela uluhlu olubanzi lwemibala kunye nemiphumo yokufiphaza, okunika iipayipi eziprintiweyo inkangeleko yobungcali nenomtsalane.
Enye inzuzo yokuprinta nge-offset kukuba inokwamkela izinto ezahlukeneyo zepayipi, kuquka irabha, iPVC, okanye isilicone. Oku kwenza ukuba ibe yindlela yokuprinta eguquguqukayo efanelekileyo kwiindlela ezahlukeneyo zokuprinta ngepayipi.
Nangona kunjalo, ukuprinta nge-offset nako kunemida yako. Kufuna izixhobo ezikhethekileyo, kuquka oomatshini bokuprinta kunye neepleyiti zokuprinta, ezinokubiza kakhulu ukuzibeka nokuzigcina zisemgangathweni. Ukongeza, ixesha lokuseta ukuprinta nge-offset lide xa lithelekiswa nezinye iindlela zokuprinta. Ke ngoko, kudla ngokuba neendleko ezingcono kwiimveliso ezinkulu kunokushicilela ngebhetshi encinci okanye ngokwesiko.
Ukuprinta isilika, okwaziwa ngokuba kukuprinta isikrini okanye i-serigraphy, kubandakanya ukutyhala i-inki kwiscreen selaphu esineembobo, kumphezulu wepayipi. Uyilo lokuprinta lwenziwa kusetyenziswa i-stencil, evala iindawo ezithile zesikrini, ivumela i-inki ukuba idlule kwiindawo ezivulekileyo iye kwipayipi.
Ukuprinta isilika kuneenzuzo ezininzi xa kuthelekiswa nokuprinta nge-offset. Okokuqala, sisisombululo esingabizi kakhulu kwimisebenzi yokuprinta encinci okanye eyenzelwe wena. Ixesha lokuseta kunye neendleko ziphantsi, nto leyo eyenza ukuba ilungele ukuprinta ngexesha elifunekayo okanye ukwenziwa kwemveliso okufutshane.
Okwesibini, ukuprinta isilika kunokufikelela kwidiphozithi ye-inki etyebileyo kumphezulu wepayipi, nto leyo ekhokelela kuyilo olucacileyo noluqaqambileyo. Oku kuyenza ifaneleke kwizicelo ezifuna iiprinti eziqinileyo nezingabonakaliyo, ezifana neelebheli zoshishino okanye iimpawu zokhuseleko.
Ukongeza, ukuprinta isilika kuvumela uluhlu olubanzi lweendidi zeinki, kuquka ii-inki ezikhethekileyo ezifana nee-inki ezingamelaniyo ne-UV, ezesinyithi, okanye ezikhazimlayo ebumnyameni. Oku kwandisa amathuba oyilo lokuprinta ipayipi, ukuhlangabezana neemfuno ezithile okanye ukuphucula impembelelo ebonakalayo yeepayipi eziprintiweyo.
Nangona kunjalo, ukuprinta isilika kunemida ethile. Akufanelanga ukufikelela kwiinkcukacha ezincinci kakhulu okanye uyilo oluntsonkothileyo olufuna ukuchaneka okuphezulu. Isisombululo kunye nobukhali bokuprinta isilika buhlala buphantsi xa kuthelekiswa nokuprinta kwe-offset. Ukongeza, ukuchaneka kombala kunye nokuhambelana kunokuphazamiseka kancinci ngenxa yendalo yenkqubo.
Ngamafutshane, zombini ukuprinta kwe-offset kunye nokuprinta isilika ziindlela ezidumileyo zokuprinta iipayipi. Ukuprinta kwe-offset kunika iziphumo ezisemgangathweni ophezulu nezichanekileyo, ezifanelekileyo kwiindlela ezintsonkothileyo kunye nokuveliswa okukhulu. Ukuprinta isilika, kwelinye icala, kubiza kancinci, kuyasebenziseka, kwaye kuvumela ukuprinta okuqinileyo, okungacacanga kunye nee-inki ezikhethekileyo. Ukukhetha phakathi kwezi ndlela zimbini kuxhomekeke kwiimfuno ezithile, uhlahlo lwabiwo-mali, kunye nesiphumo esifunekayo seprojekthi yokuprinta.
