Intshayelelo: Iglosi yomba oshicilelweyo ibhekisa kwiqondo apho isakhono sokubonakalalisa kombandela oshicilelweyo ukuya kwisibane sesiganeko sisondele kwisakhono esipheleleyo sokubonakalisa okukhethekileyo.Iglosi yezinto eziprintiweyo ikakhulu zimiselwa zizinto ezifana nephepha, i-inki, uxinzelelo lokushicilela kunye nokusetyenzwa kwe-post-press.Eli nqaku lichaza ifuthe le-inki kwiglosi yokuprinta, umxholo wereferensi yabahlobo:
Into ye-inki echaphazela ukukhazimla koshicilelo
Ubukhulu becala bubushelelezi befilimu ye-inki, echongwa yindalo kunye nobuninzi bezinto zokudibanisa.I-inki kufuneka iqulathe umbala ocolekileyo osasazwe ngokulinganayo, kwaye ibene-viscosity eyaneleyo kunye nesantya sokoma ngokukhawuleza ukuthintela ukugqobhoza okugqithisileyo kwezibophelelo kwimingxunya yephepha.Ukongeza, inki kufuneka kwakhona ube fluidity elungileyo, ukuze ukubunjwa inki egudileyo film emva kokushicilela.
01 I-Ink Film Ukutyeba
Kwiphepha eliphezulu lokufunxa i-inki binder, i-binder eseleyo isagcinwe kwifilimu ye-inki, inokuphucula ngokufanelekileyo i-luster yento eprintiweyo.Okukhona ifilimu ye-inki ijiyile, kokukhona izinto ezisaseleyo ezizidibanisayo, kokukhona zinceda ekuphuculeni ukubengezela kombandela oshicilelweyo.
Iglosi iyanda kunye nobukhulu befilimu ye-inki, nangona i-inki iyafana, kodwa iglosi yokushicilela eyenziwe ngamaphepha ahlukeneyo atshintsha ngobunzima befilimu ye-inki yahlukile.Xa ifilimu ye-inki ibhityile, iglosi yephepha eliprintiweyo iyancipha ngokunyuka kobunzima befilimu ye-inki, oku kungenxa yokuba ifilimu ye-inki igubungela iglosi ephezulu yephepha ngokwalo, kunye neglosi ye-inki ifilimu ngokwayo iyancitshiswa ngenxa. ekufunxeni kwephepha;Ngokunyuka ngokuthe ngcembe kwifilimu ye-inki, ukuxutywa kwe-binder kugcwele, kwaye ukugcinwa komphezulu we-binder kwanda, kwaye i-gloss nayo iyaphucula.
Iglosi yoshicilelo lwephepha eligqunyiweyo landa ngokukhawuleza ngokunyuka kobunzima befilimu ye-inki.Emva kokuba ubukhulu befilimu ye-inki bunyukile ukuya kwi-3.8μm, iglosi ayisayi kuphinda inyuke ngokunyuka kobunzima befilimu ye-inki.
02 I-Ink Fluidity
I-fluidity ye-inki inkulu kakhulu, ukwanda kwamachaphaza, ukwandiswa kobungakanani be-inki, umaleko we-inki obhityileyo, iglosi yokushicilela ayilunganga;Ubumanzi be-inki buncinci kakhulu, iglosi ephezulu, i-inki ayikho lula ukuyihambisa, ayilungele ukuprinta.Ngoko ke, ukuze ufumane isicwebezelisi ngcono, kufuneka ukulawula fluidity inki, hayi enkulu kakhulu ayikwazi ukuba ncinane kakhulu.
03 Umgangatho we-Inki
Kwinkqubo yokushicilela, ukuguda kwe-inki kulungile, iglosi ilungile;Umgangatho ongemhle, umzobo olula, iglosi engalunganga.
04 Umxholo we-Ink Pigment
Umxholo we-ink pigment uphezulu, kwifilimu ye-inki ingenza inani elikhulu lama-capillaries amancinci.Ukukwazi kwala manani makhulu ee-capillaries ezincinci ukugcina isibophelelo sikhulu kakhulu kunesakhono se-paper surface fiber gap ukufunxa isibophelelo.Ngoko ke, xa ithelekiswa ne-inki enebala eliphantsi, i-inki enemibala emininzi inokwenza ifilimu igcine imidibaniso engakumbi.Iglosi yeprints usebenzisa i-pigment content inki iphezulu kunaleyo yoshicilelo olunomxholo ophantsi we-pigment.Ngoko ke, amasuntswana e-ink pigment eyenziwe phakathi kwesakhiwo sothungelwano lwe-capillary yeyona nto iphambili echaphazela i-luster yezinto eziprintiweyo.
Kushicilelo lwangempela, ukusetyenziswa kwendlela yeoli ekhanyayo ukunyusa i-luster yoshicilelo, le ndlela yahluke ngokupheleleyo kwindlela yokwandisa umxholo we-pigment we-inki.Ezi ndlela zimbini zokwandisa ukukhazimla kombandela oshicilelweyo kwisicelo, ngokungqinelana nokuqulunqwa kwe-inki kunye noshicilelo lwefilimu ye-inki yoshicilelo.
Indlela yokwandisa umxholo we-pigment ulinganiselwe ngenxa yesidingo sokunciphisa umbala ekushicileleni umbala.I-inki ilungiswe ngamasuntswana amancinci e-pigment, xa umxholo we-pigment uyancipha xa i-luster yoshicilelo iya kuncitshiswa, kuphela xa ifilimu ye-inki inzima kakhulu ukuvelisa i-luster ephezulu.Ngoko ke, kule meko, indlela yokwandisa umxholo we-pigment ingasetyenziselwa ukuphucula ukukhanya kwezinto eziprintiweyo.Nangona kunjalo, inani le-pigment linganyuswa kuphela kumda othile, kungenjalo kuya kuba ngenxa yamasuntswana e-pigment ayinakugqunywa ngokupheleleyo yi-binder, ukuze ukukhanya komhlaba okusasazeka kwefilimu ye-inki kuqiniswe kodwa kukhokelela ekunciphiseni ukukhanya. yencwadi eshicilelweyo.
05 Ubungakanani kunye nokuSasazwa kweeNcam zePigment
Ubungakanani beengqungquthela ze-pigment kwi-dispersion state inquma ngokuthe ngqo imeko ye-capillary yefilimu ye-inki.Ukuba amasuntswana e-inki achama, ngakumbi iicapillaries ezincinci zinokuqulunqwa.Ukwandisa amandla efilimu ye-inki ukugcina i-binder kunye nokuphucula ukukhazimula kwezinto eziprintiweyo.Ngelo xesha, ukuba i-pigment particles iyahlakazeka kakuhle, inceda kwakhona ukwenza ifilimu ye-inki egudileyo, enokuphucula ukukhanya kwezinto eziprintiweyo.Izinto ezithintelayo ezichaphazela ukusasazwa kwamasuntswana e-pigment lixabiso le-pH lamasuntswana e-pigment kunye nomxholo we-volatile matter kwi-inki.Ixabiso le-pH le-pigment liphantsi, umxholo wezinto eziguquguqukayo kwi-inki ziphezulu, kwaye ukusasazwa kwamasuntswana e-pigment kulungile.
06 I-Ink Transparency
Emva kokwenziwa kwefilimu ye-inki ecacileyo ephezulu, ukukhanya kwesiganeko kubonakala ngokuyinxenye ngumphezulu wefilimu ye-inki, enye inxalenye yomhlaba wephepha, kwaye emva koko ibonakaliswe, isenza umbala wokucoca ezimbini, lo mboniso onzima ubonisa umphumo wombala ocebileyo;Kwaye ifilimu ye-inki eyenziwe yi-pigment opaque, i-luster yayo ibonakaliswe kuphela ngumphezulu, umphumo we-luster ngokuqinisekileyo awukho njenge-inki ecacileyo.
07 Uqhagamshelo Material Smooth
Iglosi yebhinda yeyona nto iphambili ye-inki imprinting luster.Isibophelelo se-inki sakwangoko sisekwe kwioli ye-linseed, ioli ye-tung, ioyile ye-catalpa kunye nezinye ioyile zemifuno.Ukuguda kobuso obungasemva be-conjunctiva abukho phezulu, kuphela umphezulu wefilimu enamafutha, ukubonakaliswa kokukhanya kwesiganeko, kunye neglosi yokuprinta ayilunganga.Kwaye ngoku i-resin ye-inki ye-inki njengenxalenye ephambili, i-conjunctiva eshicilelwe emva kokuba ukuguda komphezulu kuphezulu, ukukhanya kwesiganeko kubonakaliswe kuncitshisiwe, kunye ne-luster eprintiweyo iphezulu ngokuphindwe kaninzi kune-inki yokuqala.
08 Ukungena kwisinyibilikisi
Ukuprintwa kuphelile, ngenxa yokomiswa kwe-inki kunye nokulungiswa akugqitywanga, ngoko ke, iglosi yendawo yokushicilela iphezulu kakhulu, njengephepha eligqunyiweyo, indawo yayo yokushicilela kwintsimi yeglosi idla ngokuphakama kwe-15-20 degrees. kunomphezulu wephepha elimhlophe, kwaye umphezulu umanzi kwaye uyakhazimla.Kodwa njengoko i-inki isoma kwaye iqina, iglosi iyancipha ngokuthe ngcembe.Xa isinyibilikisi kwi-inki sihlala sihlala ephepheni, i-inki igcina iqondo lokumanzi kwaye inobuhle obuphezulu.Nangona kunjalo, ngokungena kwe-solvent kwiphepha, ukugudiswa komphezulu kunqunywe ngamasuntswana e-pigment, kwaye ngeli xesha iinqununu ze-pigment zikhulu kakhulu kuneemolekyuli ze-solvent, ngoko ke, ukugudiswa kwendawo yokushicilela kunye Ukungena kwi-solvent kwaye kwafuneka ukuba yehle.Kule nkqubo, izinga lokungena kwe-solvent lichaphazela ngokuthe ngqo ukugudiswa kunye nokukhanya kwendawo yokushicilela.Ukuba ukungena kuqhutywa ngokucothayo, kwaye i-polymerization ye-oxidation ye-resin yenziwa ngesantya esifanelekileyo, umphezulu we-inki unokugcinwa ngokugudileyo okuphezulu kwimeko yokuqina kwefilimu.Ngale ndlela iglosi yokushicilela inokugcinwa kwinqanaba eliphezulu.Ngokuchasene noko, ukuba ukungena kwe-solvent kukhawuleza, ukuqiniswa kwe-polymerization ye-resin kunokugqitywa kuphela xa ukugudiswa kwendawo yokushicilela kuncitshiswe kakhulu, ukwenzela ukuba i-gloss yokushicilela iyancipha kakhulu.
Ngoko ke, kwimeko yeglosi efanayo yephepha, isantya sokungena ngokukhawuleza kwe-inki, iphezulu i-gloss yokushicilela.Nokuba kwimeko yeglosi emhlophe kunye nesantya sokungena kweinki ziyafana, iglosi yokuprinta iya kwahluka ngenxa ye-inki kwiphepha lokungena kwimeko.Ngokubanzi, kwinqanaba elifanayo lokungena, imeko exineneyo kunye necolekileyo ilungele ukuphuculwa kweglosi yokuprinta kunemeko yokungena enqabileyo kunye nerhabaxa.Kodwa ukunciphisa ukungena kwe-inki kunye nesantya se-conjunctiva ukuphucula ushicilelo lweglosi kuya kubangela ukusilela kwe-inki ngasemva.
09 I-Ink Yokomisa Ifomu
Umlinganiselo ofanayo we-inki eneendlela ezahlukeneyo zokomisa, iglosi ayifani, ukomiswa kwe-conjunctiva ngokubanzi nge-oxidized kune-osmotic drying gloss iphezulu, kuba i-conjunctiva ene-oxidized yokomisa i-inki ye-inki yokudibanisa ifilimu.
