Izinto ze-Ink ezichaphazela ukuShicilela kweglosi
1 Ubukhulu befilimu ye-Ink
Kwiphepha lokwandisa ukuxutywa kwe-inki emva kwekhonkco, ikhonkco eseleyo isagcinwe kwifilimu ye-inki, enokuphucula ngokufanelekileyo i-gloss yeprint. Okukhona ifilimu ye-inki ijiyile, kokukhona isiqhagamshelo esiseleyo, kokukhona kunceda ekuphuculeni iglosi yoshicilelo.
Iglosi kunye nokunyuka kobunzima befilimu ye-inki kunye nokwanda, nangona inki efanayo, kodwa ukubunjwa kweglosi yephepha elihlukeneyo kunye nobukhulu befilimu ye-inki kunye nokutshintsha kuyahluka. Iphepha leglosi eliphezulu lokugquma kwifilimu ye-inki lincinci, i-gloss yoshicilelo kunye nokwanda kwe-inki yefilimu yobunzima kunye nokunciphisa, oku kubangelwa ifilimu ye-inki imaski yephepha ngokwayo i-gloss ephezulu yoqobo, kunye nefilimu ye-inki ngokwayo eyenziwe yi-gloss kwaye ngenxa yokufunxa kwephepha kunye nokunciphisa; ngokunyuka ngokuthe ngcembe kubunzima befilimu ye-inki, iphepha ekufunjweni kwezinto zokudibanisa ngokusisiseko lihluthiswe emva kokunyuka kwenani lezinto zokudibanisa ezigcinwe kumphezulu, kwaye i-gloss iphucula rhoqo.
Ushicilelo lwekhadibhodi eqatywe iglosi kunye nokwanda kobungqingqwa befilimu ye-inki buyanda ngokukhawuleza, kwifilim ye-inki ubukhulu bonyuka ukuya kwi-3.8μm emva kokuba isilungiseleli seglosi asisayi kuphinda sinyuke ngokunyuka kobunzima befilimu ye-inki.
2Ubumanzi be-inki
Ubumanzi be-inki bukhulu kakhulu, ichaphaza liyanda, ubukhulu boshicilelo buyandiswa, umaleko we-inki uba bhityile, iglosi yokushicilela ayilunganga; ulwelo lwe-inki luncinci kakhulu, iglosi ephezulu, i-inki ayilula ukuyihambisa, kodwa ayilungele ukuprinta. Ngoko ke, ukuze ufumane isilungiseleli seglosi esingcono, kufuneka ulawule ubumanzi be-inki, ungabi nkulu kakhulu hayi kancinci.
3Umgangatho we-inki
Kwinkqubo yokushicilela, ukulinganisa kwe-inki kulungile, emva koko iglosi ilungile; ukulinganisa okungahambi kakuhle, kulula ukutsala, emva koko iglosi ayilunganga.
4 Isiqulatho sePigment kwi-inki
Isiqulatho se-pigment esiphezulu se-inki sinokwenza inani elikhulu lee-capillaries ezincinci ngaphakathi kwefilimu ye-inki. Kwaye eli nani likhulu lokugcinwa kwe-capillary entle yokukwazi ukudibanisa izinto, kunomphezulu wephepha lomsantsa wefayibha ukufunxa ukukwazi ukudibanisa izinto zikhulu kakhulu. Ngoko ke, xa zithelekiswa nee-inki ezinebala eliphantsi, ii-inki ezinombala ophezulu we-pigment zinokwenza ifilimu igcine ikhonkco elidibanisa ngakumbi. Iglosi yento eprintiweyo kusetyenziswa ii-inki ezinomxholo we-pigment ephezulu iphezulu kune-inki enomxholo ophantsi we-pigment. Ke ngoko, ubume benethiwekhi ye-capillary eyenziwe phakathi kwamasuntswana e-inki ye-pigment yeyona nto iphambili echaphazela iglosi yoshicilelo.
Ekushicileleni kwangempela, ukusetyenziswa kwendlela yeoli yeglosi ukunyusa iglosi yokuprinta, le ndlela ihluke ngokupheleleyo kwindlela yokwandisa umxholo we-pigment we-inki. Ezi ndlela zimbini zokwandisa iglosi yoshicilelo kwisicelo, ngokuhambelana namacandelo e-inki kunye noshicilelo lwefilimu ye-inki yokushicilela ukukhetha.
Indlela yokwandisa umxholo we-pigment inqunyelwe yimfuno yokuvelisa umbala ekushicileleni umbala. I-inki eyenziwe ngamasuntswana e-pigment amancinci, xa umxholo we-pigment uyancipha, iglosi yeprinta iyancipha, kuphela xa ifilimu ye-inki inzima kakhulu ukuvelisa iglosi ephezulu. Ngoko ke, indlela yokwandisa umxholo we-pigment ingasetyenziselwa ukuphucula i-gloss yento eprintiweyo. Nangona kunjalo, inani le-pigment linganyuswa kuphela kumda othile, ngaphandle koko kuya kuba ngenxa yamasuntswana e-pigment ayinakugutyungelwa ngokupheleleyo yinto edibanisayo, ukuze i-inki ifilimu ifilimu yokukhanya okukhanyayo iyenze ibe mandundu endaweni yokukhokelela ekunciphiseni iglosi yento eprintiweyo.
5Ubungakanani bamasuntswana ebala kunye neqondo lokusasazeka
Ubungakanani be-pigment particles kwi-digment state inquma ngokuthe ngqo imeko ye-inki yefilimu ye-capillary, ukuba iincinci ze-inki zincinci, zinokwenza i-capillary encinci. Ukwandisa amandla efilimu ye-inki ukugcina ikhonkco kunye nokuphucula i-gloss yokushicilela. Ngelo xesha, ukuba i-pigment particles ihlakazeke kakuhle, inceda kwakhona ukwenza ifilimu ye-inki egudileyo, enokuphucula i-gloss yokushicilela. Izinto ezilawulayo ezichaphazela iqondo lokusasazeka kwamasuntswana epigment yi-pH yamasuntswana epigment kunye nobungakanani bezinto eziguquguqukayo kwi-inki. Ukusasazwa kwamasuntswana e-pigment kulungile xa ixabiso le-pH le-pigment liphantsi kwaye umxholo wezinto eziguquguqukayo kwi-inki ziphezulu.
6Ukucaca kwe-inki
Emva kokuba ifilimu ye-inki yenziwe nge-inki nge-transparency ephezulu, inxalenye yokukhanya kwesiganeko ibonakaliswa ngumphezulu wefilimu ye-inki, kwaye enye inxalenye ifikelela kumphezulu wephepha kwaye ibonakaliswe kwakhona, isenza ukuhluzwa kwemibala emibini, kwaye oku kubonakaliso kuyinkimbinkimbi kutyebisa umphumo wombala; ngelixa ifilimu ye-inki eyenziwe yi-opaque pigment ikhazimlayo kuphela ngokubonakala komphezulu, kwaye umphumo weglosi ngokuqinisekileyo awulunganga njenge-inki ecacileyo.
7Iglosi yezinto ezidibanisayo
Iglosi yesixhobo sokudibanisa yeyona nto iphambili yokuba iiprinta ze-inki zinokuvelisa iglosi, i-inki yokuqala yokudibanisa i-oyile ye-linseed, ioli ye-tung, ioyile ye-catalpa kunye nezinye ioyile yemifuno, ukuguda komphezulu wefilimu emva kokuba ifilimu ingekho phezulu, inokubonisa kuphela umphezulu wefilimu etyebileyo, ukukhanya kwesehlo ukwenza ukubonakaliswa okungahambi kakuhle, iiprinta. Kule mihla, imathiriyeli yokudibanisa ye-inki ikakhulu yenziwe nge-resin, kwaye umphezulu ogudileyo we-inki emva kokugquma uphezulu, kwaye ukubonakaliswa kokukhanya kwesiganeko kuncitshisiwe, ngoko ke ukukhazimla kwe-inki kuphezulu ngokuphindwe kaninzi kune-inki yokuqala.
8Ukomisa uhlobo lwe-inki
Umlinganiselo ofanayo we-inki usebenzisa iindlela ezahlukeneyo zokomisa, iglosi ayifani, ngokubanzi ukomisa ifilimu ene-oxidized kunokuba iglosi yokungena iphezulu, kuba ifilimu ene-oxidized yokomisa i-inki kwi-film-forming linker material ngakumbi.
Uyiphucula njani iglosi yokuprinta?
1 Nciphisa i-inki emulsification
Nciphisa iqondo le-inki emulsification. Ukuprintwa kwe-offset kwi-inki emulsification kubangelwa ikakhulu kukusebenza kwamanzi kunye ne-inki, ushicilelo lubukeka njengomaleko ongqindilili we-inki, kodwa iimolekyuli ze-inki kwimo ye-oyile emanzini, i-gloss yokomisa ihlwempuzekile kakhulu, kwaye iya kuvelisa uthotho lwezinye iintsilelo.
2 izongezo ezifanelekileyo
Yongeza abancedisi ezifanelekileyo kwi-inki, uyakwazi ukunyenyisa ukuprintwa kwe-inki ukuze ushicilelo olugudileyo. Abancedisi ngokubanzi bongezwa kwixabiso le-inki, abayi kudlula i-5%, ukuba uqwalasela umphumo wegloss, kufuneka ube ngaphantsi okanye ungafaki. Kodwa i-surfactant ye-fluorocarbon yahlukile, inokuthintela umaleko we-inki we-orange peel, imibimbi kunye nezinye iziphene zomhlaba, kwaye kwangaxeshanye unokuphucula umphezulu weglosi yokushicilela.
3 Ukusetyenziswa ngokuchanekileyo kweoli yokomisa
Ukusetyenziswa ngokuchanekileyo kweoli yokomisa. Kwinqanaba eliphezulu elikhazimlayo elikhawulezayo lokumisa inki, kwimeko yobushushu kunye nokufuma kuqhelekile, ngokwayo inomthamo owaneleyo wokumisa.
Kwimeko yezi meko zilandelayo, ioli yokomisa kufuneka yongezwe:
① Kwimeko yobushushu obuphantsi kunye nokufuma ebusika;
② inki kufuneka yongezwe kwi-anti-adhesive, i-anti-adhesive, i-oyile yokulungelelanisa inki encinci, njl., kufuneka ifakwe kwioli yokomisa.
Kwinkqubo yokusebenza, ukusetyenziswa ngokuchanekileyo kweoli eyomileyo, ukwenzela ukubunjwa kweglosi yemveliso egqityiweyo kukulungele kakhulu. Oku kungenxa yokuba iphepha lokufunxa izinto zekhonkco lidinga ixesha elithile, kwinkqubo, ngokukhawuleza ukwenza ukudibanisa kwezinto zekhonkco, de kube ifilimu yomile, isitshixo seglosi yemveliso egqityiweyo.
4 Ukulungelelaniswa komatshini
Lungiselela ngokuchanekileyo umatshini. Nokuba ubungqingqwa be-inki yoshicilelo lufikelela kumgangatho, lukwanefuthe kwiglosi. Umzekelo: ulungelelwaniso loxinzelelo olubi, inqanaba lokwandiswa kwamachaphaza liphezulu, ubukhulu bomaleko we-inki abuhambelani nomgangatho, iglosi yemveliso egqityiweyo imbi kakhulu. Ngoko ke, ukulungelelanisa uxinzelelo, ukwenzela ukuba ulawulo lwamachaphaza okwandisa malunga ne-15%, imveliso eprintiweyo ye-inki layer inzima, inqanaba kunye nokutsala kuvulekile, iglosi ikhona.
5 Lungisa ugxininiso lwe-inki
Yongeza amanzi e-Fanli (No. 0 ioli), le viscosity yeoli inkulu kakhulu, inzima, iyakwazi ukulungelelanisa i-inkinki yoxinaniso, ukwenzela ukuba i-inkino encinci ikhulise, ikhulise i-gloss yemveliso eprintiweyo.
