isebenza njani ioffset yoshicilelo

Isebenza Njani i-Offset Printing?

I-offset printing yindlela yoshicilelo ethandwayo nesetyenziswa ngokubanzi equka ukudlulisa umfanekiso oyinki ukusuka kwipleyiti ukuya kwingubo yerabha, uze ugqitywe kwindawo yokushicilela. Le nkqubo iyaziwa ngokuvelisa umgangatho ophezulu, iziphumo ezihambelanayo, okwenza kube yindlela yokuya kwiimfuno ezininzi zoshicilelo lwezorhwebo. Kweli nqaku, siza kugocagoca kwiinkcukacha ezintsonkothileyo zendlela ushicilelo lweoffset olusebenza ngayo, ukusuka kulungiselelo lokuqala ukuya kwimveliso yokugqibela.

Iziseko zoShicilelo lwe-Offset

I-offset printing, ekwabizwa ngokuba yi-lithography, isekelwe kumgaqo wokuba ioli namanzi azixubani. Inkqubo iqala ngokudala ipleyiti yokushicilela equlethe umfanekiso oza kushicilelwa. Le pleyiti ine-inki, kunye ne-inki enamathele kuphela kwiindawo zemifanekiso kwaye kungekhona iindawo ezingezizo umfanekiso. Umfanekiso weinki ugqithiselwa kwingubo yerabha, kwaye ekugqibeleni uye kwindawo yokushicilela, nokuba liphepha, ikhadibhodi, okanye enye into.

Ushicilelo lwe-Offset lubizwa ngokuba yi-"offset" ngenxa yokuba i-inki ayikhutshelwa ngqo ephepheni. Endaweni yoko, ifakwa kwingubo yerabha ngaphambi kokuba ifike ephepheni. Le ndlela engathanga ngqo yokudlulisa umfanekiso iphumela ekushicileleni okubukhali, okucacileyo okukhululekile kwiimpawu zomphezulu weplate.

Inkqubo yoshicilelo lwe-offset ivumela ukuhambelana, iziphumo ezikumgangatho ophezulu, ziyenze ifaneleke ukushicilelwa okukhulu kunye noluhlu olubanzi lwezicelo zokushicilela. Ukususela kumaphephandaba kunye namaphephancwadi ukuya kwiincwadana ezinemifanekiso kunye nokupakishwa, ukushicilela nge-offset yindlela yokushicilela eguquguqukayo nethembekileyo.

Inkqubo yoShicilelo ye-Offset

Inkqubo yoshicilelo yeoffset ibandakanya amanyathelo abalulekileyo aliqela, ngalinye lidlala indima ebalulekileyo ekwenzeni imveliso yokugqibela eshicilelweyo. Ngezantsi, siza kuphonononga la manyathelo ngokweenkcukacha.

1. Ukwenza iipleyiti: Inyathelo lokuqala kwinkqubo yokushicilela ngeoffset kukwenza iipleyiti. Umfanekiso oza kuprintwa udluliselwe kwipleyiti yesinyithi usebenzisa inkqubo ye-photomechanical okanye photochemical. Emva koko le pleyiti ixhonywa kumatshini wokushicilela.

2. Ibhalansi ye-Ink kunye naManzi: Emva kokuba iplate ifakwe kwi-press, isinyathelo esilandelayo kukuphumeza ibhalansi echanekileyo ye-inki kunye namanzi. Iindawo ezingeyiyo imifanekiso yeplate ziphathwa ukuba zifumane amanzi, ngelixa iindawo zemifanekiso zenziwe zamkela i-inki. Olu lungelelwano luyimfuneko ekuveliseni umfanekiso ococekileyo, obukhali.

3. Ukuprinta: Ngeplate esele ilungile kunye ne-inki kunye nebhalansi yamanzi iseti, inkqubo yokushicilela ngokwenene inokuqalisa. Ipleyiti idibana nengubo yerabha, ethi yona idlulisele umfanekiso kwindawo yokushicilela.

4. Ukugqiba: Emva kokuba umfanekiso ukhutshelwe kwindawo yokushicilela, izinto eziprintiweyo zinokungena kwiinkqubo ezongezelelweyo ezifana nokusika, ukusonga, kunye nokubopha ukugqiba imveliso yokugqibela.

5. Ukulawulwa koMgangatho: Kuyo yonke inkqubo yokushicilela, amanyathelo okulawula umgangatho akhona ukuze kuqinisekiswe ukuba izinto eziprintiweyo ziyahlangabezana nemigangatho efunwayo. Oku kusenokuquka ukungqanyaniswa kombala, ukujonga naziphi na iziphene, nokwenza uhlengahlengiso njengoko kuyimfuneko.

Izinto eziluncedo kuShicilelo lwe-Offset

Ushicilelo lweoffset lubonelela ngeengenelo ezininzi ezifak’ isandla ekusetyenzisweni kwalo ngokubanzi kushishino lokushicilela.

1. Iziphumo zoMgangatho oPhezulu: Ukuprintwa kwe-Offset kuvelisa imifanekiso ebukhali, ecocekileyo enomgangatho ohambelanayo. Ukuhanjiswa okungathanga ngqo komfanekiso kwindawo yoshicilelo kuphelisa naziphi na iimpawu zomphezulu wepleyiti, okukhokelela kushicilelo olucacileyo noluchanekileyo.

2. Iindleko eziSebenzayo kuShicilelo oluKhulu: Ushicilelo lwe-Offset luneendleko ezisebenzayo kushicilelo olukhulu, njengoko iindleko zokuqala zokuseta zisasazwa kwinani elikhulu leeprints. Oku kwenza kube lukhetho olufanelekileyo kwiiprojekthi ezifuna ubuninzi bezinto eziprintiweyo.

3. Ukuguquguquka kwezinto ezininzi: Ukushicilela nge-offset kunokusetyenziswa kwiindawo ezininzi zokushicilela, kuquka iphepha, amakhadibhodi, neeplastiki ezithile. Oku kuguquguquka kuyenza ifaneleke kwizicelo ezahlukeneyo zokuprinta, ukusuka kwiincwadi kunye neemagazini ukuya kwipakethe kunye nezixhobo zokwazisa.

4. Ukuchaneka koMbala: Ngokuprintwa kwe-offset, kunokwenzeka ukufezekisa ukuhambelana kombala ngokuchanekileyo, okwenza kube yinto efanelekileyo kwiiprojekthi ezifuna ukuveliswa kombala ngokuchanekileyo kunye nokuhambelana.

5. Uluhlu Olubanzi Lokugqibezela Iinketho: Ushicilelo lwe-Offset luvumela iindlela ezahlukeneyo zokugqiba, ezifana neengubo, iilaminates, kunye ne-embossing, ukuphucula inkangeleko kunye nokuqina kwezinto ezishicilelweyo.

Ikamva Loshicilelo lwe-Offset

Kwixesha ledijithali, ukuprintwa kwe-offset kuyaqhubeka kuyindlela efanelekileyo kunye nexabisekileyo yokushicilela. Ngelixa ushicilelo lwedijithali lufumene ukuthandwa ngenxa yoncedo lwalo kunye namaxesha okutshintsha ngokukhawuleza, ushicilelo lwe-offset luhlala luyindlela yokukhetha iiprojekthi ezifuna umgangatho ophezulu kunye nokungaguquguquki.

Ukuhambela phambili kobugcisa bokushicilela i-offset kuye kwakhokelela ekuphuculeni ukusebenza kakuhle kunye nokuzinza kwendalo. Ukusuka kwiinkqubo zekhompyuter ukuya kwipleyiti ezisusa imfuno yefilimu ukuya kusetyenziso lwee-inki ezilungele indalo kunye neecoatings, ushicilelo lweoffset luyaphucuka ukuze luhlangabezane neemfuno zoshicilelo lwanamhlanje.

Njengoko imbonakalo yomhlaba yoshicilelo iqhubeleka nokuvela, ushicilelo lweoffset luza kuhlala lungundoqo kushishino loshicilelo lwezorhwebo, oluxatyiswa ngomgangatho walo obalaseleyo, ukuguquguquka, kunye nokusebenza kakuhle kweendleko zoshicilelo olukhulu.

Ukuqukumbela, ukushicilela ngeoffset yindlela yokushicilela ekudala ivavanywa nenokuthenjwa eqhubeka ihlangabezana neemfuno zemizi-mveliso eyahlukahlukeneyo. Ngokukwazi ukuvelisa iziphumo ezikumgangatho ophezulu, ezingaguquguqukiyo kuluhlu olubanzi lwemigangatho yoshicilelo, ushicilelo lweoffset luhlala lusisiseko soshishino lokushicilela, lubonelela ngeengenelo ezingenakuphikiswa kunye nekamva elithembisayo.
