Ibhokisi yebhokisi yecuba iprintiwe iphepha elipheleleyo, kwaye ukuprintwa kwayo akulunganga?
Iifektri zeebhokisi zeecuba zihlala zifumana iiodolo ezivela kubathengi abaneempawu ezithile okanye iimfuno ezikhethekileyo, kwaye kufuneka benze ushicilelo lwebhokisi yeecuba olupheleleyo ngemibala eyahlukeneyo. Xa kuthelekiswa neeodolo eziqhelekileyo zoshicilelo lweebhokisi zeecuba, ushicilelo lwebhokisi yeecuba olupheleleyo kufuneka luprinte yonke ikhadibhodi yeebhokisi zeecuba, ebiza kakhulu, inzima, kwaye ichitha imali. Ixabiso liphezulu.
Kwiphepha elipheleleyo lokuprinta ibhokisi yecuba, umphathi wokuprinta ibhokisi yecuba kufuneka anikele ingqalelo engakumbi kulawulo lweenkcukacha. Ukuba awuyinaki, kuya kubakho iingxaki ezinje ngokuprinta ibhokisi yecuba emhlophe, ukuba mnyama kombala weinki, ukulahleka kweinki yokuprinta ibhokisi yecuba, ukutsala okanye ukuprinta okungalunganga, njl.njl., okubangela ukuba abaphathi bazaliswe ngamazwi. Ukuprinta ibhokisi yecuba kwipleyiti yokuprinta akulunganga okanye akunakuprintwa.ibhokisi yekhandlela
Xa kuvela ezi ngxaki zingasentla, kucetyiswa ukuba abaphathi bajonge ezi ndawo zi-5 zilandelayo kuqala, nto leyo enokusombulula uninzi lweengxaki zokuprinta ibhokisi yecuba epheleleyo.
Indawo yokuqala: jonga i-anilox roller kunye ne-raber roller
Xa ulungisa umatshini, qwalasela ngokukodwa ukuba amacala omabini e-anilox roller kunye ne-raber roller alungelelene na. Siyazi ukuba umsebenzi we-raber roller kukucinezela i-inki kumphezulu we-anilox roller, kwaye i-anilox roller inokubonelela nge-inki ngokuzinzileyo kwipleyiti yokuprinta ibhokisi yecuba ngendlela yobuninzi. Xa iqela lee-roller lisebenza, zijikeleza nge-centrifugally kwaye zikhuhlane, kwaye zikwimeko efana ne-parabolic.ibhokisi yetshokholethi
Ukuba ke iindawo ezikumacala omabini amaqela amabini eerola zilinganisiwe, oko kunxulumene ngqo nokufana kokudluliselwa kweyinki kunye nokuxubha i-yinki, okuchaphazela umgangatho wezinto eziprintiweyo, kwaye kunokuthintela ingxaki yombala weyinki ongaguqukiyo ngaphambi nasemva kwezinto eziprintiweyo kakhulu.
Indawo yesibini: jonga ubukhulu bepleyiti/bekhadibhodi
Kubalulekile ukwazi ukuba yonke ipleyiti yokuprinta igcina ubukhulu obufanayo ukuqinisekisa uxinzelelo olufanayo lokuprinta ibhokisi yecuba kunye ne-inki kuyilo. Xa ubukhulu bepleyiti yokuprinta ibhokisi yecuba bungalingani, kuya kubakho umahluko ngokuphakama kuyilo. Apho uyilo luphezulu, kulula ukuncamathisela ipleyiti, kwaye apho uyilo luphantsi, kulula ukuba ne-inki engaphelelanga, nto leyo ebangela ukuprintwa okungacacanga kunye nezinye iingxaki.
Ngendlela efanayo, ukuba ikhadibhodi ebotshelelweyo inezimbobo ngexesha lokuphathwa kwayo, xa kuprintwa ibhokisi yecuba, umphezulu wephepha lembobo uya kuba neziphene ezisemgangathweni kunye neempawu ezingacacanga, ngoko ke jonga ngononophelo phambi kokuba uyivelise.
Indawo yesithathu: Jonga i-mesh ye-anilox roller
Irola ye-anilox ikwabizwa ngokuba “yintliziyo yomatshini wokuprinta ibhokisi yecuba”. Umsebenzi wayo uchaphazela ngokuthe ngqo ubunono kunye nokufana kokuprinta ibhokisi yecuba. Xa ubhala, amandla okufunxa i-inki awanelanga.
Xa isakhiwo se-mesh sikwi-90 degrees, ukudluliselwa kwe-inki kuya kukhula kube yimicu; ukuba yi-120 degrees, isakhiwo siya kuba sikwere ngakumbi. Okwangoku, umatshini wokuprinta ibhokisi yecuba ye-flexographic eqhelekileyo udla ngokusebenzisa ulungiselelo lwe-60 degrees, kwaye i-mesh yi-ceramic eqhelekileyo ye-hexagonal. I-inki inikezelwa yi-anilox roller, ukuze ukudluliselwa kwe-inki kube ngcono, kwaye uxinzelelo lokushicilela lube luncinci kwaye amanqaku okuhamba kwamanzi abe sezantsi.
Okwesine: Jonga i-inki esekwe emanzini
Kwimveliso, ukuba inkqubo yokubonelela ngeinki ivaliwe kwaye i-inki ilahlekile; xa i-roller yerabha kunye ne-anilox roller zidibene ngendlela eqhelekileyo, i-inki eludongeni lwe-anilox roller mesh ayinakucinywa, njl.njl., ezihambelana ngokusisiseko ne-viscosity ephezulu ye-inki esekelwe emanzini.
Siyazi ukuba ngexesha lokuprinta ibhokisi yecuba egcwele iphepha, ubungakanani beyinki esetyenzisiweyo bukhulu kwaye ukusetyenziswa kwayo kuyakhawuleza, kwaye i-yinki iya kuqina ngokukhawuleza. Ubuninzi beyinki esekwe emanzini bunolwalamano oluthile olulinganayo nobungakanani beyinki edluliselweyo. Ii-inki ezingcono ezisekwe emanzini ziya kwandisa ukufunxwa kwayo yinki, ngoko ke kuyacetyiswa ukusebenzisa ii-inki ezisekwe emanzini eziphakathi neziphezulu ukuprinta ibhokisi yecuba epheleleyo, kwaye uqaphele ukujonga utshintsho lwe-viscosity yee-inki ezisekwe emanzini ngexesha lenkqubo yemveliso.ibhokisi yeentyatyambo
