I-inki yokuprinta i-gravure yolwelo iyoma xa umntu esebenzisa indlela ebonakalayo, oko kukuthi, ngokuphuma kwe-solvents, kunye ne-inki yezinto ezimbini ngokunyanga ngamakhemikhali.
Yintoni iGravure Printing
I-inki yokuprinta i-gravure yolwelo iyoma xa umntu esebenzisa indlela ebonakalayo, oko kukuthi, ngokuphuma kwe-solvents, kunye ne-inki yezinto ezimbini ngokunyanga ngamakhemikhali.
Zithini iingenelo kunye neengxaki zokuprinta i-gravure?
Umgangatho ophezulu wokuprinta
Ubungakanani beinki esetyenziswa ekuprinteni igravure bukhulu, imizobo kunye nombhalo zinomvakalelo ocacileyo, kwaye iileya zityebile, imigca icacile, kwaye umgangatho uphezulu. Uninzi lokuprintwa kweencwadi, iimagazini, imifanekiso, ukupakishwa kunye nokuhombisa kukuprintwa kwegravure.
Ukuprinta okuphezulu
Umjikelo wokwenza iipleyiti zokuprinta igravure mde, ukusebenza kakuhle kuphantsi, kwaye iindleko ziphezulu. Nangona kunjalo, ipleyiti yokuprinta ihlala ixesha elide, ngoko ke ifanelekile ukuprinta ngobuninzi. Okukhona ibhetshi inkulu, kokukhona inzuzo iphezulu, kwaye ukuprinta ngebhetshi encinci, inzuzo iphantsi. Ke ngoko, indlela yegravure ayifanelekanga ukuprinta iibhetshi ezincinci zeempawu zorhwebo.
(1) Iingenelo: ukubonakaliswa kweyinki malunga ne-90%, kwaye umbala utyebile. Ukuveliswa kombala okunamandla. Ukumelana okunamandla koyilo. Inani leeprinti likhulu. Ukusetyenziswa kwamaphepha amaninzi, ngaphandle kwezixhobo zephepha nako kunokuprintwa.
(2) Iingxaki: iindleko zokwenza iipleyiti zibiza kakhulu, iindleko zokuprinta nazo zibiza kakhulu, umsebenzi wokwenza iipleyiti unzima kakhulu, kwaye inani elincinci leekopi eziprintiweyo alifanelekanga.
Iisubstrate
I-gravure ingasetyenziswa kwizinto ezahlukeneyo, kodwa idla ngokusetyenziselwa ukuprinta iphepha neplastiki yodidi oluphezulu.
Imbonakalo yeeprinti: Uyilo lucocekile, lufana, kwaye akukho zimpawu zokungcola ezicacileyo. Imifanekiso kunye nombhalo zibekwe ngokuchanekileyo. Umbala wepleyiti yokuprinta uyafana ngokusisiseko, impazamo yobukhulu bokuprinta okucolekileyo ayidluli kwi-0.5mm, ukuprinta ngokubanzi akudluli kwi-1.0mm, kwaye impazamo yokuprinta ngaphezulu kwamacala angaphambili nangasemva ayidluli kwi-1.0mm.
FAQ
Ukungaphumeleli kokuprinta igravure kubangelwa kakhulu ziipleyiti zokuprinta, ii-inki, ii-substrates, ii-squeegists, njl.njl.
(1) Umbala weyinki ulula kwaye awulingani
Utshintsho lombala we-inki oluvela rhoqo kwizinto eziprintiweyo luyenzeka. Iindlela zokususa ziquka: ukulungisa ukujikeleza kwerola yepleyiti, ukulungisa i-engile kunye noxinzelelo lwe-squeegee okanye ukuyitshintsha ngentsha.
(ii) Iprinti ithambile kwaye inoboya
Umfanekiso wento eprintiweyo ulinganiswe kwaye unamathelisiwe, kwaye umphetho womfanekiso kunye nombhalo ubonakala ngathi yi-burrs. Iindlela zokususa zezi: ukususa umbane ongashukumiyo kumphezulu we-substrate, ukongeza izinyibilikisi ze-polar kwi-inki, ukwandisa ngokufanelekileyo uxinzelelo lokuprinta, ukulungisa indawo ye-squeegee, njl.
3) Ingxaki yokuba i-inki evimbayo yome kwindawo enemingxuma yepleyiti yokuprinta, okanye indawo enemingxuma yepleyiti yokuprinta izaliswe buboya bephepha kunye nomgubo wephepha, ibizwa ngokuba yi-blocking plate. Iindlela zokususa zezi: ukwandisa umxholo we-solvents kwi-inki, ukunciphisa isantya sokomisa i-inki, kunye nokuprinta ngephepha elinamandla aphezulu.
4) Ukuchitheka kwe-inki kunye nokubonakala kwamabala kwindawo eprintiweyo. Iindlela zokususa zezi: ukongeza i-oyile ye-inki eqinileyo ukuphucula i-viscosity ye-inki. Lungisa i-engile ye-squeegee, wandise isantya sokuprinta, tshintsha i-deep mesh printing plate nge-shallow mesh printing plate, njl.njl.
5) Iimpawu zokukrwela: Iimpawu ze-squeegee kwizinto eziprintiweyo. Iindlela zokususa ziquka ukuprinta ngee-inki ezicocekileyo ngaphandle kokungena kwezinto zangaphandle. Lungisa i-viscosity, ukoma, kunye nokunamathela kwe-inki. Sebenzisa i-squeegee esemgangathweni ophezulu ukulungisa i-engile phakathi kwe-squeegee kunye nepleyiti.
6) Ukuna kwemibala
Ingxaki yokukhanyisa umbala kwiprinti. Iindlela zokususa ezi zinto zilandelayo: ukuprinta ngee-inki ezisasazekileyo kakuhle kunye nokusebenza okuzinzileyo. Izongezo ezichasene nokuhlangana kunye nezokuthintela ukuna kwemvula zongezwa kwi-inki. Songa kakuhle kwaye uvuselele i-inki ekwi-inki rhoqo.
(7) Ingxaki yokuba amabala e-inki kwizinto eziprintiweyo ezinamathelayo. Iindlela zokususa zezi: khetha ukuprinta i-inki ngesantya esikhawulezayo sokuguquguquka, unyuse ubushushu bokomisa okanye unciphise ngokufanelekileyo isantya sokuprinta.
(8) Ukuchithwa kweinki
I-inki eprintwe kwifilimu yeplastiki ayinamatheli kakuhle kwaye ikhuhlwa ngesandla okanye ngamandla oomatshini. Iindlela zokususa zezi: ukuthintela ifilimu yeplastiki ekufuma, khetha ukuprintwa kwe-inki ngokuhambelana kakuhle nefilimu yeplastiki, phinda ufake ifilimu yeplastiki phezu kwayo, kwaye uphucule uxinzelelo lomphezulu.
Iindlela zophuhliso
Ngenxa yokukhuselwa kwendalo kunye nezizathu zempilo, ukutya, amayeza, icuba, utywala kunye nezinye izimboni zinika ingqalelo ngakumbi kukhuseleko lwendalo lwezinto zokupakisha kunye neenkqubo zokuprinta, kwaye amashishini okuprinta i-gravure anika ingqalelo ngakumbi kwindalo yeendawo zokusebenzela zokuprinta. Ii-inki kunye neevarnish ezinobuhlobo nokusingqongileyo ziya kuba zithandwa ngakumbi, iinkqubo zokucinezela ezivaliweyo kunye nezixhobo zokutshintsha ngokukhawuleza ziya kwenziwa zidume, kwaye ii-gravure presses ezilungiselelwe i-inki ezisekelwe emanzini ziya kusetyenziswa kakhulu.
