I-inki yokushicilela yegravure elulwelo iyoma xa ubani esebenzisa indlela yokwenyama, oko kukuthi, ngokujika kwezinto ezinyibilikisayo zibe ngumphunga, nee-inki zamacandelo amabini ngokunyanga ngemichiza.
Yintoni iGravure Printing
I-inki yokushicilela yegravure elulwelo iyoma xa ubani esebenzisa indlela yokwenyama, oko kukuthi, ngokujika kwezinto ezinyibilikisayo zibe ngumphunga, nee-inki zamacandelo amabini ngokunyanga ngemichiza.
Ziziphi iingenelo kunye nokungalunganga koshicilelo lwe-gravure.
Umgangatho woshicilelo oluphezulu
Umthamo we-inki osetyenziswayo kushicilelo lwegravure mkhulu, imizobo kunye nesicatshulwa sinemvakalelo yeconvex, kwaye iileya zityebile, imigca icacile, kwaye umgangatho uphezulu. Uninzi lokuprintwa kweencwadi, amaphepha-ncwadi, imifanekiso, ukupakishwa kunye nokuhombisa kukuprintwa kwegravure.
Ukushicilelwa kwevolumu ephezulu
Umjikelo wokwenza ipleyiti yoshicilelo lwegravure mde, ukusebenza kakuhle kuphantsi, kwaye ixabiso liphezulu. Nangona kunjalo, ipleyiti yokushicilela ihlala ixesha elide, ngoko ifanelekile ukushicilelwa kobuninzi. I-batch enkulu, inzuzo ephezulu, kunye nokushicilela ngebhetshi encinci, inzuzo iphantsi. Ngoko ke, indlela ye-gravure ayifanelekanga ukuprintwa kweebhatshi ezincinci zeempawu zorhwebo.
(1) Izinto eziluncedo: imbonakalo ye-inki imalunga nama-90%, kwaye umbala utyebile. Ukuveliswa kombala okunamandla. Ukuchasana koyilo oluqinileyo. Inani leeprints likhulu. Ukusetyenziswa koluhlu olubanzi lwamaphepha, ngaphandle kwezinto zephepha nazo zinokuprintwa.
(2) Iingxaki: iindleko zokwenza iipleyiti ziyabiza, iindleko zokushicilela nazo ziyabiza, umsebenzi wokwenza iipleyiti untsonkothe ngakumbi, yaye inani elincinane lemibhalo eshicilelweyo ayifanelekanga.
Iisubstrates
I-Gravure ingasetyenziselwa kuluhlu olubanzi lwezinto eziphathekayo, kodwa isoloko isetyenziselwa ukuprinta iphepha eliphezulu kunye nefilimu yeplastiki.
Imbonakalo yoshicilelo: Uyilo lucocekile, lufana, kwaye akukho manqaku acacileyo amdaka. Imifanekiso kunye nesicatshulwa zibekwe ngokuchanekileyo. Umbala wepleyiti yoshicilelo ngokusisiseko uyafana, impazamo yobungakanani boshicilelo olucokisekileyo alukho ngaphezu kwe-0.5mm, ushicilelo oluqhelekileyo alukho ngaphezu kwe-1.0mm, kwaye impazamo yokushicilela yangaphambili nangasemva ayikho ngaphezu kwe-1.0mm.
FAQ
Ukungaphumeleli kwi-gravure printing kubangelwa ikakhulu ngamacwecwe okushicilela, ii-inki, i-substrates, i-squeegists, njl.
(1) Umbala we-inki ukhaphukhaphu kwaye awulingani
Ukutshintsha kombala we-inki ngamaxesha athile kwenzeka kumbandela oshicilelweyo. Izindlela zokuphelisa zibandakanya: ukulungisa ukujikeleza kwe-plate roller, ukulungelelanisa i-angle kunye noxinzelelo lwe-squeegee okanye ukutshintshela entsha.
(ii) Ushicilelo lunamanqatha kwaye lunoboya
Umfanekiso wento eprintiweyo ibekwe ngokwemigangatho kwaye incamathelisiwe, kwaye umphetho womfanekiso kunye nombhalo uvela burrs. Iindlela zokuphelisa zi: ukususa umbane osisigxina phezu kwe-substrate, ukongeza i-solvents ye-polar kwi-inki, ngokufanelekileyo ukwandisa uxinzelelo lokushicilela, ukulungelelanisa indawo ye-squeegee, njl.
3)Isenzeko sokuba i-inki yokuvala yome kumnatha wepleyiti yokuprinta, okanye umngxuma onomnatha wepleyiti yokushicilela uzaliswe ziinwele zephepha kunye nomgubo wephepha, ubizwa ngokuba yi-blocking plate. Iindlela zokuphelisa zezi: ukwandisa umxholo we-solvents kwi-inki, ukunciphisa isantya sokumisa inki, kunye nokushicilela ngephepha elinamandla aphezulu.
4) Ukuchithwa kwe-inki kunye nokubona kwinxalenye yentsimi yomba oshicilelweyo. Iindlela zokuphelisa zezi: ukongeza ioli ye-inki enzima ukuphucula i-viscosity ye-inki. Lungisa i-angle ye-squeegee, ukwandisa isantya sokushicilela, buyisela ipleyiti yokushicilela ye-mesh enzulu kunye nepleyiti yokushicilela ye-mesh engekho, njl.
5) Amanqaku okukrwela: Imigca ye-squeegee kumbandela oshicilelweyo. Iindlela zokuphelisa ziquka ukuprinta ngee-inki ezicocekileyo ngaphandle kokungena kwamanye amazwe. Lungisa i-viscosity, ukoma, ukunamathela kweyinki. Sebenzisa umgangatho ophezulu we-squeegee ukulungisa i-angle phakathi kwe-squeegee kunye nepleyiti.
6) Imvula ye-pigment
Isenzeko sokukhanyisa umbala kushicilelo. Iindlela zokuphelisa zezi: ukuprinta ngeenki ezinokusasazwa kakuhle kunye nokusebenza okuzinzileyo. I-Anti-agglomeration kunye ne-anti-precipitation additives yongezwa kwi-inki. Roll kakuhle kwaye uvuselele i-inki kwitanki ye-inki rhoqo.
(7)Into eyenzeka kumabala e-inki kwizinto ezincangathi eziprintiweyo. Iindlela zokuphelisa zezi: khetha ushicilelo lwe-inki kunye nesantya sokutshintsha ngokukhawuleza, ukwandisa ubushushu bokumisa okanye ukunciphisa ngokufanelekileyo isantya sokushicilela.
(8) Ukuchithwa kwe-inki
I-inki eprintiweyo kwifilimu yeplastiki ayinakunamatheli kakuhle kwaye ikhuhlwa ngesandla okanye ngamandla omatshini. Iindlela zokuphelisa zezi: thintela ifilimu yeplastiki ekunyakameni, khetha ukuprintwa kwe-inki ngokuhambelana kakuhle nefilimu yeplastiki, phinda ujonge ifilimu yeplastiki, kwaye uphucule ukuxinezeleka komphezulu.
Iindlela zophuhliso
Ngenxa yokhuseleko lokusingqongileyo kunye nezizathu zempilo, ukutya, amayeza, icuba, utywala kunye namanye amashishini ingqalelo ngakumbi nangakumbi ukukhuselwa kokusingqongileyo izinto zokupakisha kunye neenkqubo yoshicilelo, kunye namashishini gravure yoshicilelo ingqalelo ngakumbi kubume yocweyo yoshicilelo. Ii-inki ezihambelana nokusingqongileyo kunye neevanishi ziya kuthandwa ngakumbi, iinkqubo ezivaliweyo ze-squeegee kunye nezixhobo zokutshintsha ngokukhawuleza ziya kuthandwa, kwaye ii-presses ze-gravure eziguqulelwe kwii-inki ezisekelwe emanzini ziya kusetyenziswa ngokubanzi.
