Iihambo ku offset: iintlobo eziphambili

Ukuze Cazulula yoshicilelo offset, esebenzisa iindidi ezimbini ezisisiseko, kunye nokwahlulwa zabo. offset ahluka yi ubukho okanye ukungabikho ukufuma inkqubo yokuvelisa (iinkcukacha ezithe vetshe) kunye Uhlobo lwemidiya esetyenziswa kule nkqubo.

Ngokwezi umahluko ukufuma offset:

• zemveli;
• owomileyo.

Ngokwemiqathango eendaba ahluka:

• lwabavoti;
• ephepheni;
• elimxinwa screen;
• esibanzi;
• full-ubude.

Makhe sihlolisise ngokweenkcukacha ngalunye kwezi ntlobo nokuchaza iimpawu ngobuwena ngamnye offset.

Traditional offset okanye offset ne moistening

Olu khetho kukudala imveliso eshicilelweyo uthathwa Classic. Ukuyekwa nge ukufuma mu yothuba elithile ke ixhaphake kakhulu ukushicilela koomatshini ehlabathini lonke. Nangona kwixesha elizayo, kunye nezinye iiteknoloji ushicilelo zibe kakuhle eqhelekileyo ngakumbi, kuba kule ndawo ahlala ukuphucuka.

Shicilela ngokusebenzisa amacwecwe okushicilela ezizodwa, apho zizaliswe iindawo ezimhlophe kunye print iziqalelo. Ngamafutshane, khona apho imveliso yokugqibela yileta okanye umqondiso kwifom eshicilelweyo Yimbonakaliso, yaye apho kuyimfuneko ukwenza isithuba okanye indawo, ibekwe izinto esimhlophe.

izinto eziprintiweyo umdla idayi kunye non kutsala amanzi. Le nkqubo yokusetyenziswa kwekhompyutha kwaye isebenzisa amacwecwe ezizodwa, apho zikhutshwa yinkampani ezizodwa. iimilo ezinjalo kakhulu eqhelekileyo, kwaye ngexabiso eliphantsi xa kuthelekiswa kunye neefom phantsi eyomileyo offset.

elomileyo offset

A iteknoloji entsha wadala yinkampani Toray Industries (saseJapan) ngo-1982. Yobuchwepheshe inkqubo owomileyo lisisiqalo ngakumbi kancinane inzima, nangona ngengqiqo, kwaye ibhexesha imisebenzi zabasebenzi yoshicilelo. Ngokukodwa, kwinkqubo yoshicilelo na ulawulo umlinganiselo wamanzi kunye inki kwi isicombululo emthonjeni zifuna.

iindawo sisithuba esimhlophe apha zizakubalulwa ezifakelwa abicah ngohlobo eprintiweyo. Iifom ezinjalo azixhaphakanga, kodwa ubunzima iphambili ukufumana nokuthenga nedayi ukuze eyomileyo offset. Ezi iidayi ziveliswa nzima olunzulu iresiphi kunye nenani eliqingqiweyo abenzi.

Ngoku nibuyele lucalulo yoshicilelo lisisiqalo kwi eendaba ezisetyenziswayo. Yenethiwekhi lwenzelwe apha material lisetyenziswa kumfanekiso lokugqibela kwipleyiti yoshicilelo.

Le web offset

Carrier apha kukunikezelwa kuthiwa-, oko kukuthi, umqulu iphepha esikhulu. Okokuqala, iphepha ethubeleza phantsi ifomu eshicilelweyo incwadi esongwayo uze emva koko usike zibe ubungakanani ethile kwaye isongiwe.

izixhobo mqengqeleki zidla ifakiwe kuphela ezivenkileni print omkhulu. izixhobo ezifana lubiza kakhulu kwaye ke ngoko iindleko-kuphela kwimizi-mveliso omkhulu. Ubukhulu becala kwi iyunithi kuluhlu owenza ushicilelo runs kuphela omkhulu.

sheet offset

Asinto nzima ukuqonda, kukho abathwali sheets ngamnye. Amahobe cylinder, nto leyo ifumaneka kwi kwipleyiti wokushicilela, ukwahlukanisa yemakhishithi nganye idluliselwa ngokusebenzisa iikomityi sokufunxa. Emva kaloliwe yamanyala kuvela umfanekiso othile.

In lwalo ofanelekileyo, ngoko nangoko emva kubonakala ehlelayo lokuqala ngokupheleleyo-umbala yoshicilelo, kodwa eneneni, kwezixhobo ezininzi yoshicilelo unayo inombolo oyifunayo macandelo. Ngoko ke wokulaminetha sheets ezifunekayo ngokusebenzisa iisilinda izihlandlo eziliqela ukuze ufumane umfanekiso oyifunayo. Ngoko ixesha ngalinye kufuneka ukulungelelanisa yenethiwekhi ukuze kubangela uluvo ngokomfuziselo.

Ukongeza, kukho kunye neeyunithi zoshicilelo eziliqela izixhobo. units Ezo ndlela ilungileyo ngokuyila umfanekiso multi-elimbala. Wokulaminetha ngokulandelana ngokwamacandelo eziliqela yenethiwekhi ofumana umbala ehambelana kwi sites web efanelekileyo.

Le iintlobo ethandwa kwaye isetyenziswa ukwenza uluhlu olubanzi iimveliso eshicilelweyo:

• nokudalwa ziswe iintengiso nokurhweba;
• oolindixesha ukuphindaphindeka;
• yoshicilelo ileyibheli;
• imveliso iifom;
• ukulungiselela iingxelo zonyaka;
• yoshicilelo poster (http://www.giprint.ru/plakaty/);
• iiphakheji izgtovlenie.

Kukho ezinye iintlobo ze yamaxwebhu ashicilelweyo, adla ziveliswa ngale ndlela offset.

emxinwa-format offset

Kuba aba matshini le web isetyenziswa ene-njengomlinganiso ezinqamlezayo ngeesentimitha eziyi-ukusuka kwisiqingatha ukuya 60. Ubukhulu becala emxinwa-format ukulinganisa, maxa wambi ibizwa ngokuba ezinesiqingatha isetyenziselwa ukwenza iimveliso for yorhwebo print ekumgangatho ophezulu.

esibanzi lulungisa

I web ke has ubungakanani eninzi ububanzi, leyo isusela ukusuka iisentimitha 135 ukuya 190. Native extra-elikhulu, uluhlu lweemveliso langabom yi zahlukahlukene kakhulu ekudaleni ikhadi ukuya iimagazini ezinkulu-ejikeleza kunye namaphephandaba.

full-ubude offset

I web ubukhulu sangqa ukusuka ngeesentimitha 84 leemitha. Ngako oko, kuyenzeka ukuba bathi olu hlobo ifomati medium offset. uluhlu olwahlukeneyo iimveliso zingenziwa apha:

• iincwadi;
• ngamaxesha athile;
• ukuphakheja;
• iikhathalogu;
• iimagazini.

Kufuneka kuqwalaselwe ukusetyenziswa indlela unako ukuphucula ukusebenza kwezixhobo, xa kudalwa iimagazini. Ngexesha lenkqubo yoshicilelo ngexesha elifanayo utywine imiqulu ezimbini. Ngaphezu koko, ezi rolls idityaniswe esebenzisa isixhobo ngokusonga zahlanganiswa ukuba phephancwadi ngokulandelelana.
