Iphepha lokuxhaswa: uhlelo lokusebenza nezinhlobonhlobo

Iphepha lokuxhaswa yizinto ezihloswe ngokuyinhloko ekudaleni izincwadi zokubonisa nokunyathelisa kwemikhiqizo ebonwayo. Ubuningi bamashidi wokunyathelisa kwe-offsets buhluka kusuka ku-60 kuya ku-220 g / m. Ngokuvamile umkhiqizo uhlelwe njengephepha eliphezulu elinamandla elikhiqizwa kusuka ku-cellulose ehlanzekile ngokufaka izinkuni zamapulangwe, okuphikisana nokuguquguquka ngaphansi kwethonya lesikhamanzi esinyene.

Njengoba iphepha elihlehlisiwe lisetshenziselwa ukuphrinta, ikhwalithi yalo ihambisana nezidingo ezinzima, ezibangelwa ubuchwepheshe bokunyathelisa. Imingcele ebaluleke kunazo zonke ihlanganisa ukuqina, amandla, ukulinganisa, absorbency nokuzinza komzimba uma kunamanzi.

Ngokusho kobuchwepheshe bokushicilela amashidi okunyathelisa othintana nombhede werabha, okudinga umkhiqizo wezakhiwo ezinhle kakhulu zezakhiwo. Ukwandisa amandla okusebenza ngesikhathi sokukhiqiza, ukunciphisa uthuli lwayo nokuhlunga. Ukwenza lokhu, ubuso buhlanganiswe nokubunjwa okhethekile, okungeziwe khona izithasiselo nezigcwalisi.

Ngesisindo, iphepha elihlaselwe lizuza ukunyuka kwamanzi okunyuka. Ezingxenyeni ze-cellulose, amanzi awangena kalula, kodwa lokhu akuphazamisi ukugcizelela nokwakheka kwepende. Empeleni, absorbency yiyona impahla ebaluleke kunazo zonke impahla. Uma amashidi engenawo amanzi, umswakama awukwazi ukungena kumdwebo bese uhlala ekhasini lokushicilela lephrinta. Uma imingcele ye-absorbency idlulela kujwayelekile, umkhiqizo uzoqala ukuthola umbala osevele usuka ku-cylinder yokugqoka, okuzokwenza kube lula ukukhenyuka koqweqwe lwaphezulu.

Iphepha lokuxhaswa lisetshenziswe ezincwadini. Ithole uhlelo lokusebenza ekukhiqizeni izinhlu, amapheshana, izincwajana, amaflaya nezinye izinto zokuphromotha nezokukhangisa. Ngaphezu kwalokho, le ndaba isetshenziselwa ukushicilelwa amaphephandaba omagazini abamnyama nabamhlophe nabombala.

Ukuphila komsebenzi wephepha eliqhelile kuxhomeke kokuqukethwe kwepulp kuni. Ukukhiqizwa kwezikhathi kungcono ukusebenzisa amashidi ngokuqukethwe kwalezi zinto ezingekho ezingamaphesenti angama-75. Ukuze ukhiqize imikhiqizo ephrintiwe edinga impilo ende, kufanele udle izinto ezihlanzekile ze-cellulose.

Iphepha lokuxhaswa, intengo yalo ephakeme kuneminye imikhiqizo efanayo, ihlukaniswe ibe yimbozi, i-cartographic, ephephandabeni kanye ne-offset. Ukuze kusetshenziswe imidwebo yemibala ngemidwebo ye-halftone yokuphila kwesikhathi eside, kusetshenziswe izinto ezenziwe nge-cellulose ehlanzekile.

Futhi, iphepha lihlukaniswe ngemikhiqizo. Isigaba "A" sihlinzekela ukukhishwa kwezincwadi ezinezibalo zokuphila eshalofini. Umaka "B" usetshenziselwa ukukhiqizwa ngokuhlukaniswa kombala okulula nokukhanya okunciphise. Ukuze kusetshenziswe amaphephandaba, iphepha eliphezulu lokuqhelelanisa ama-offset lisetshenziswe, elinesimo esithuthukisiwe, esichazwe ngobude bokuphuka.

Amashidi aphethwe angaba nombuthano owodwa noma ohlangothini oluhlangene, ubushelelezi obuphakathi, ukukhanya okumhlophe nokwehliswa. Loluhlobo lwezinto ezivame ukusetshenziselwa ukudala imikhiqizo ebonisa imibala.
