Ushicilelo lweoffset kunye noshicilelo lwesilika ziindlela ezimbini ezidumileyo zokushicilela ezisetyenziswa kwiindawo ezahlukeneyo, kuquka imibhobho. Nangona zisebenza injongo enye yokudlulisela uyilo kwimibhobho, kukho umahluko omkhulu phakathi kwezi nkqubo zimbini.
I-offset printing, ekwaziwa ngokuba yi-lithography okanye i-offset lithography, bubuchule bokushicilela obubandakanya ukudlulisa i-inki ukusuka kwipleyiti yokushicilela ukuya kwingubo yerabha, ethi emva koko iqengqele i-inki kumphezulu wombhobho. Inkqubo ibandakanya amanyathelo amaninzi, kubandakanywa nokulungiselela umzobo, ukudala ipleyiti yokushicilela, ukusebenzisa i-inki kwi-plate, kunye nokudlulisa umfanekiso kwi-hose.
Enye yeengenelo eziphambili zoshicilelo lweoffset kukukwazi ukuvelisa imifanekiso ekumgangatho ophezulu, eneenkcukacha, nebukhali kwimibhobho. Oku kuyenza ibe lukhetho oludumileyo loshicilelo oluchanekileyo olufana neelogo, okubhaliweyo, okanye uyilo oluntsonkothileyo. Ukongezelela, ukuprintwa kwe-offset kuvumela uluhlu olubanzi lwemibala kunye nemiphumo ye-shading, ukunika i-hoses eprintiweyo imbonakalo yobungcali kunye nembonakalo ebonakalayo.
Enye inzuzo yoshicilelo lwe-offset kukuba inokufaka izixhobo ezahlukeneyo ze-hose, kuquka irabha, i-PVC, okanye i-silicone. Oku kuyenza ibe yindlela yoshicilelo eguquguqukayo elungele usetyenziso olwahlukileyo lombhobho.
Noko ke, ushicilelo lweoffset nalo lunemida yalo. Kufuna izixhobo ezikhethekileyo, kuquka oomatshini bokushicilela neepleyiti zokushicilela, ezinokubiza imali eninzi ukuseta nokuyilungisa. Ukongeza, ixesha lokuseta loshicilelo lweoffset lide xa lithelekiswa nezinye iindlela zokushicilela. Ke ngoko, ihlala inexabiso elithe xhaxhe kwimveliso yemveliso emikhulu kunebhetshi encinci okanye ushicilelo oluqhelekileyo.
ushicilelo lwesilika, okwakwaziwa njengoshicilelo lwesikrini okanye i-serigraphy, ibandakanya ukutyhala i-inki kwiscreen selaphu elinobukroti, phezu kombhobho. Uyilo lokushicilela lwenziwa ngokusebenzisa i-stencil, evimba iindawo ezithile zesikrini, ivumela inki ukuba idlule kwiindawo ezivulekileyo kwi-hose.
Ushicilelo lwesilika lubonelela ngeenzuzo ezininzi xa kuthelekiswa noshicilelo lweoffset. Okokuqala, sisisombululo esinexabiso elithe kratya lemisebenzi yoshicilelo oluncinci okanye oluqhelekileyo. Ixesha lokuseta kunye neendleko zisezantsi kakhulu, oko kuyenza ilungele ushicilelo olufunwayo okanye olufutshane lwemveliso.
Okwesibini, ukuprintwa kwesilika kunokufikelela kwidiphozithi ye-inki engqindilili kumphezulu wombhobho, okukhokelela kuyilo olubalaseleyo noludlamkileyo. Oku kuyenza ifaneleke izicelo ezifuna ukuprinta okungqindilili, okucacileyo, okufana neeleyibhile zamashishini okanye iimpawu zokhuseleko.
Ukongeza, ushicilelo lwesilika luvumela uluhlu olubanzi lweentlobo ze-inki, kubandakanywa ii-inki ezikhethekileyo ezifana ne-UV-resistant, metallic, okanye i-glow-in-the-dark inki. Oku kwandisa amathuba okuyila ukuprintwa kwe-hose, ukuhlangabezana neemfuno ezithile okanye ukunyusa impembelelo ebonakalayo yeepayipi eziprintiweyo.
Nangona kunjalo, ukuprintwa kwesilika kunemida ethile ngokunjalo. Ayikufanelanga ukuzuza iinkcukacha ezintle kakhulu okanye uyilo oluntsonkothileyo olufuna ukuchaneka okuphezulu. Isisombululo kunye nokubukhali koshicilelo lwesilika lusezantsi xa kuthelekiswa noshicilelo lweoffset. Ukongezelela, ukuchaneka kombala kunye nokuhambelana kungaphazamiseka kancinane ngenxa yobume bencwadi yenkqubo.
Ngamafutshane, zombini ushicilelo lweoffset kunye noshicilelo lwesilika ziindlela ezidumileyo zokushicilela kwimibhobho. Ushicilelo lwe-Offset lubonelela ngeziphumo ezikumgangatho ophezulu kunye nezichanekileyo, ezifanelekileyo kuyilo oluntsonkothileyo kunye nokuqhutywa kwemveliso emikhulu. Ukuprintwa kwesilika, kwelinye icala, kuyabiza, kuyaguquguquka, kwaye kuvumela ushicilelo oluqinileyo, opaque kunye nee-inks ezikhethekileyo. Ukhetho phakathi kwezi ndlela zimbini luxhomekeke kwiimfuno ezithile, uhlahlo lwabiwo-mali, kunye nesiphumo esinqwenelekayo seprojekthi yoshicilelo.
