UkuGqwesa koShicilelo lwe-Offset: Ukuchaneka kunye noMgangatho woShicilelo

Ushicilelo lwe-Offset bubuchule obusetyenziswa kakhulu ekushicileleni iintlobo ngeentlobo zemathiriyeli ezifana neencwadi, amaphephandaba, iimagazini, izinto zokubhala, kunye nokupakishwa. Inika umgangatho ophezulu wokushicilela umgangatho, ukusebenza kakuhle kweendleko, kunye nokuguquguquka, okwenza kube lukhetho oludumileyo kumashishini amaninzi kunye nemibutho. Kweli nqaku, siza kuphonononga ukuchaneka kunye nomgangatho onikezela ngoshicilelo lwe-offset, kunye neenkqubo ezibandakanyekayo ekuphumezeni ukugqwesa kushicilelo.

Inkqubo yoShicilelo ye-Offset

I-offset printing, ekwabizwa ngokuba yi-lithography, isekelwe kumgaqo wokuba ioli namanzi azixubani. Inkqubo ibandakanya ukuhanjiswa kwe-inki ukusuka kwipleyiti ukuya kwingubo yerabha, ethi ke isebenzise i-inki kwindawo yokushicilela. Le ndlela ivumela ukuprintwa okuchanekileyo kunye nokuhambelanayo, okwenza kube yinto efanelekileyo kwiiprojekthi eziphezulu kunye nemveliso enkulu.

Inkqubo yokushicilela i-offset iqala ngokudala iipleyiti zokushicilela, ngokuqhelekileyo zenziwe nge-aluminiyam okanye i-polyester. Ezi cwecwe zixhonywe ngomfanekiso oza kushicilelwa kusetyenziswa inkqubo yokukrola i-photochemical okanye i-laser. Emva koko amacwecwe afakwe kwiisilinda kumatshini wokushicilela, kwaye umfanekiso udluliselwe kwiingubo zerabha. Ukusuka apho, i-inki ithunyelwa ephepheni okanye kwenye indawo yokushicilela, nto leyo ephumela kumfanekiso otsolo nokumgangatho ophezulu oshicilelweyo.

Ushicilelo lwe-Offset luyaziwa ngokukwazi ukuvelisa iinkcukacha ezintle kunye nemibala eqaqambileyo, iyenze ilungele uluhlu olubanzi lwezicelo zokushicilela. Ikwafaneleke ngokufanelekileyo ukuprintwa kwiindidi ezahlukeneyo zephepha kunye nezixhobo, kubandakanywa izitokhwe ezigqunyiweyo nezingafakwanga, kunye namaphepha akhethekileyo. Ukukwazi ukufikelela kwiziphumo ezichanekileyo nezingaguqukiyo kwenza ushicilelo lweoffset lube lolona khetho lubalaseleyo kwiiprojekthi ezifuna owona mgangatho uphezulu.

Izinto eziluncedo kuShicilelo lwe-Offset

Kukho iingenelo ezininzi zokusebenzisa ushicilelo lweoffset kumthamo ophezulu kunye neeprojekthi zoshicilelo olukumgangatho ophezulu.

Ushicilelo lwe-Offset lukwabonelela ngokhetho loshicilelo lwesiko, olufana noshicilelo lwedatha oluguquguqukayo, oluvumela ukwenziwa kwezinto eziprintiweyo. Oku kunokuba luncedo ngakumbi kumaphulo okuthengisa ekujoliswe kuwo kunye nonxibelelwano lomntu. Ubuchule bokwenza izinto eziprintiweyo ngokwezifiso zongeza omnye umaleko wexabiso kushicilelo lwe-offset, nto leyo eyenza ibe yindlela eguquguqukayo nesebenzayo yoshicilelo kuluhlu olubanzi lwezicelo.

Ulawulo loMgangatho kwi-Offset Printing

Ukuqinisekisa ukuchaneka kunye nomgangatho kushicilelo lwe-offset kufuna ukuthotyelwa ngokungqongqo kwimigangatho yolawulo lomgangatho kuyo yonke inkqubo yoshicilelo. Oku kubandakanya ukuqwalaselwa okucokisekileyo kwiinkcukacha ekudalweni kwamacwecwe okushicilela, kunye nokubekwa kweliso rhoqo kunye nokugcinwa komatshini wokushicilela ukuze kuqinisekiswe iziphumo ezingaguqukiyo nezichanekileyo.

Ulawulo lomgangatho kushicilelo lweoffset luqala ngokulungiswa kwamacwecwe okushicilela, okubandakanya ukukrolwa ngononophelo komfanekiso oza kushicilelwa. Oku kufuna ukuchaneka kunye nokuchaneka ukuqinisekisa ukuba umfanekiso oshicilelweyo wokugqibela uhlangabezana nemigangatho yomgangatho oyifunayo. Emva kokuba iipleyiti zixhonywe kumatshini wokushicilela, oomatshini bokushicilela bamele babeke iliso elibukhali inkqubo yokushicilela ukuze babone baze balungise nayiphi na imiba enokuvela.

Enye yezinto eziphambili zolawulo lomgangatho kwi-offset yoshicilelo kulawulo lombala. Ukufezekisa ukuveliswa kombala okuchanekileyo kunye nokuhambelanayo kufuna ukusetyenziswa kweeprofayili zombala ezilinganisiweyo kunye nokuhlolwa ngononophelo kwemveliso yombala kuyo yonke inkqubo yokushicilela. Oku kunceda ukuqinisekisa ukuba izinto zokugqibela eziprintiweyo zihlangabezana nemigangatho yombala ejoliswe kuyo kwaye zigcine umgangatho ophezulu wokuthembeka kombala.

Ukongeza kulawulo lwemibala, ulawulo lomgangatho kushicilelo lweoffset lukwabandakanya ukulungiswa rhoqo kunye nokulinganisa umatshini wokushicilela. Oku kubandakanya ukubeka iliso kumanqanaba e-inki, ukujonga nayiphi na imiba yomatshini, kunye nokuqinisekisa ukuba umatshini wokushicilela ulungelelaniswe ngokufanelekileyo kwaye ulungelelanise umsebenzi ngamnye wokushicilela. Ngokugcina umatshini wokushicilela ukwimeko efanelekileyo, abaqhubi banokunciphisa ukuhluka kunye neziphene kwizinto eziprintiweyo, ukuqinisekisa ukuba isiqwenga ngasinye sihlangabezana nemigangatho ephezulu yomgangatho.

UbuGcisa bokuQeda ubuGcisa

Ukongeza kokuchaneka kunye nomgangatho ophunyezwe ngenkqubo yoshicilelo lwe-offset, ubuchule obukhethekileyo bokugqiba bunokuphucula ngakumbi inkangeleko kunye nokusebenza kwezinto eziprintiweyo. Ezi ndlela zingabandakanya iinketho ezahlukeneyo zokugqoka, ukubopha, kunye nokuhombisa okongeza umnxeba okhethekileyo kunye nobugcisa kwimveliso egqityiweyo.

Olunye ukhetho oludumileyo lokugqiba olukhethekileyo kukusetyenziswa kweengubo zokunyusa ukubonakala kunye nokuqina kwezinto eziprintiweyo. Oku kunokubandakanya iinketho ezifana ne-varnish okanye i-UV yokugqoka, enokuthi ifake i-glossy okanye i-matte ekugqibeleni kwisiqwenga esiprintiweyo, kunye nokubonelela ngokukhuseleka kokugqoka kunye nokukrazula. Iingubo zokwaleka zisenokwandisa ukushukuma kwemibala kwaye zenze izinto eziprintiweyo zibe nomtsalane ngakumbi kwaye zikhangeleke.

Olunye ubuchule bokugqiba obukhethekileyo kukusetyenziswa kweenketho zokubopha, ezifana nokuthunga isali, ukubopha ngokugqibeleleyo, okanye ukubopha i-spiral, ukudala iimveliso ezigqityiweyo njengeencwadi, iikhathalogu kunye neemagazini. Ezi zikhetho zibophelelayo zibonelela ngendlela yobuchwephesha kunye nesebenzayo yokubonisa izinto eziprintiweyo, ezivumela ukuphathwa ngokulula kunye nokuqina kwexesha elide. Ubuchwephesha bokubopha obukhethekileyo bunokubandakanya ukusetyenziswa kwamaphepha akhethekileyo kunye nezixhobo zokugquma ukunyusa ngakumbi imbonakalo kunye namava abambekayo emveliso egqityiweyo.

Imihombiso efana ne-foil stamping, i-embossing, kunye ne-die-cutting inokongeza ubunewunewu kunye nokwahlukileyo kwizinto eziprintiweyo, ezizenza zivelele kwaye zishiye impembelelo engapheliyo. Obu buchwephesha bokugqiba bukhethekileyo bunokusetyenziswa ukwenza iimveliso eziprintiweyo ezibonwayo nezingaqhelekanga, zizenze zilungele iiprojekthi ezifuna inqanaba elongezelelweyo lomgangatho kunye nobugocigoci. Ngokudibanisa ukuchaneka koshicilelo lweoffset kunye neendlela ezikhethekileyo zokugqiba, amashishini kunye nemibutho inokudala imathiriyeli eprintiweyo engeyiyo kuphela ekumgangatho ophezulu kodwa ebukekayo kwaye enefuthe.

Ukuqukumbela

Ukuqukumbela, ushicilelo lwe-offset lubonelela ngenqanaba eliphezulu lokuchaneka kunye nomgangatho ekushicileleni, oko kukwenza kube lolona khetho lubalaseleyo kuluhlu olubanzi lwezicelo. Inkqubo yokushicilela ye-offset, kunye nokukwazi kwayo ukuvelisa iinkcukacha ezintle kunye nemibala eqaqambileyo, inika iziphumo ezihambelanayo nezibukhali ezihlangabezana nemigangatho ephezulu yomgangatho. Xa kudityaniswa nobuchule obukhethekileyo bokugqiba, ukushicilela ngeoffset kunokuvelisa izinto ezishicilelweyo ezingezizo nje ukubonakala kakuhle kodwa nezisebenzayo nezihlala ixesha elide.

Iingenelo zoshicilelo lweoffset, kubandakanywa ukusebenza kakuhle kweendleko, ukuguquguquka, kunye nobuchule bokwenza izinto ezishicilelweyo ngokwezifiso, kuyenza ibe yindlela yoshicilelo eguquguqukayo nesebenzayo kumashishini kunye nemibutho. Ngokugcina ulawulo oluluqilima lomgangatho kuyo yonke inkqubo yoshicilelo kunye nokusetyenziswa kobuchule bokugqiba obukhethekileyo, amashishini anokufikelela elona nqanaba liphezulu lomgangatho kwizinto zawo eziprintiweyo, enze impembelelo ehlala ihleli kubaphulaphuli bawo.

Lilonke, ukugqwesa koshicilelo lwe-offset kuphunyezwa ngokuchaneka, ingqalelo kwiinkcukacha, kunye nokuzinikela kumgangatho, okukhokelela kwizinto eziprintiweyo ezihlangabezana nemigangatho ephezulu yokugqwesa kushicilelo. Enoba kuveliswa iincwadi, amaphephancwadi, ukupakishwa, okanye izinto zokupapasha, ukushicilela ngeoffset kunikeza ukuchaneka nomgangatho ofunwa ngamashishini nemibutho ukuze aprinte iincwadi zawo.
