Intshayelelo kwinkqubo yokwenza indebe yephepha yeumatshini wekomityi yephepha!
Ukubumba ngephanyazo!Mandazise inkqubo yokwenza ye iikomityi zephepha.
Okokuqala, iphepha elisetyenziselwa ukwenza izikhongozeli zephepha kufuneka libe liphepha lebakala lokutya.Iphepha lebakala lokutya lithengwa kakhulu lisuka eYurophu nase-United States, kwaye lithathwa njengelona bakala libalaseleyo phakathi kwemathiriyeli yephepha.Emva koko, inkqubo ye-laminating kufuneka iqhutywe kuqala, kwaye izinto ezinokuthi zixhathise ioli kunye namanzi zifakwe kwiphepha lephepha ngaphambi kokuba amanyathelo okubumba alandelayo aqhutywe.
Ukugquma ngumaleko omncinci kakhulu wezinto zeplastiki ezincanyathiselwe kwiphepha, ukwenzela ukuba ikomityi yephepha ikwazi ukumelana neoli kunye namanzi, kwaye ingabamba iziphuzo kunye neesuphu ixesha elide.Ukukhethwa kwezinto zokugqoka kuhambelana neempawu zeekomityi zephepha ezilandelayo.Eli linyathelo lokwenza iindebe yephephayomelele kwaye intle.
Emva kokunyangwa kwe-lamination, iphethini efunwayo kunye nombala uya kuprintwa kumqulu wephepha.Iindlela zokuprinta zinokwahlulwa zibe ziindlela ezi-3: igravure, ipleyiti yeconvex, kunye nepleyiti ecaba.Ixabiso legravure liphezulu kakhulu, kwaye ngoku linqabile ukusetyenziswa;ushicilelo lweletterpress lushicilelwa ngokuqhubekayo kwimiqulu yamaphepha, kwaye umthamo wokushicilela ofunekayo mkhulu.Ukuprintwa kwe-lithographic, apho iphepha linqunyulwa libe ngamaqhekeza kwaye liprintwe, lifanelekile ukwenza ixabiso elincinci leemveliso.Emva kokuba inki isetyenzisiwe, enye ingqimba yonyango lweglosi yamanzi iya kuprintwa njengokhuseleko.
Abanye abavelisi basebenzisa indlela "yokushicilela kwi-inki", ukuprinta kuqala kwaye emva koko bafake i-laminating, kunye nokufaka i-inki kwifilimu yokucoca.Le ndlela yokuvelisa inezinga eliphezulu lokunxiba kwaye ngoko ke ixabiso eliphezulu.Kodwa kungakhathaliseki ukuba luhlobo luni lwendlela yokushicilela esetyenziswayo, izinto zokuprinta zezikhongozeli ezidibana nokutya kufuneka zibe kumgangatho wokutya ukuqinisekisa ukhuseleko lokusetyenziswa.
Iphepha eliprintiweyo lingena kwi-knife mold kwaye livelise iphepha elifana nefeni, eliyimilo evulekileyo yodonga lwekomityi.Iphepha elinemilo yefeni liyaqokelelwa lize lithunyelwe kumatshini wokwenza, kwaye iphepha liqengqeleke liphume kwikomityi yokubumba ibe yimo yekomityi yephepha.Ngelo xesha, i-mold inika ukushisa kwi-seam yephepha, ukwenzela ukuba i-PE ibhujiswe ngokutshisa kwaye inamathele omnye komnye, kwaye i-bottom yekomityi yephepha ihlanganiswe.Kwangoko emva kokuba umngundo utyhale umlomo wendebe, iphepha elisemlonyeni wendebe liqengqeleka lize lilungiswe bubushushu ukuze lenze umphetho wendebe.indebe yephepha.La manyathelo okwenzayo angagqitywa ngomzuzwana omnye.
Ikomityi yephepha egqityiweyo ithunyelwa kumatshini wokuhlola ukuze kuqinisekiswe ukuba imilo iphelile ngaphandle komonakalo, kwaye indawo yangaphakathi ihlambulukile kwaye ayinamabala.Ikomityi yephepha egqityiweyo ingena kwinkqubo yokupakisha kwaye ilindele ukuthunyelwa.
