Ukunyathelisa isikhathi eside ngamapulangwe aqoshiwe
Ukunyathelisa kwe-Gravure-nakho kwaziwa njengokushicilelwa kwe-rotogravure-ngokuyinhloko kuyindlela yokunyathelisa ehamba phambili, ephakeme kakhulu, ephakeme kakhulu. Njengokuqoshwa, ukuqoshwa uhlobo lwe-intaglio yokunyathelisa okwenza kahle, izithombe ezinemininingwane. Ingasetshenziselwa ukunyathelisa kwe- CMYK lapho umbala ngamunye weyinki usebenza yi-cylinder yayo kanye nezinyathelo zokumisa phakathi.
Njengomshini we- flexography , ukunyathelisa kwe-gravure kuvamise ukusetshenziselwa ukunyathelisa okuphezulu kwe-emaphaketheni, iphepha lokunamathisela kanye nesipho. Nakuba ukunyathelisa okungavamile, ukunyathelisa kungasetshenziselwa ukunyathelisa omagazini, amakhadi okubingelela, nezicucu zokukhangisa eziphezulu.
Indlela I-Gravure isebenza ngayo
Ekunyathelweni kokukhishwa, isithombe si-asidi-esakhiwe phezu kwensimbi yensimbi yensimbi eyodwa yombala ngamunye-iphethini lamaseli. Amaseli ahlala e-cylinder, ngokungafani nokunyathelisa okushicilelwe noma i-letterpress lapho isithombe sokuphrinta sikhuliswa noma sithanda ukunyathelisa, lapho isithombe silinganisa ne-plate.
I-cylinder isetshenziswe ngamaseli ezinzulu ezihlukahlukene. Lawa maseli abamba inkinobho edluliselwa ku-substrate. Ubukhulu bamaseli kumele bube ncamashi ngoba amaseli ajulile akhiqiza umbala ojulile kunamaseli angajulile.
Amaseli agcwele uyinki, kanti izingxenye ezingekho zokuphrinta zeplate noma isilinda ziyasulwa noma zikhishwe inki yamahhala. Khona-ke iphepha noma enye i-substrate icindezelwe ngokumelene ne-cylinder enezinkinobho emshinini wokujikeleza, futhi isithombe sidluliselwa ngqo ephepheni, ngokungafani nokunyathelisa kwe-offset, okusebenzisa i-cylinder yangaphakathi. I-cylinder eqoshiwe ihlala ingena emthonjeni we-inki, lapho iqoqa khona inkinobho yokugcwalisa amaseli ayo aphelile ekushintsheni komunye umshini.
Imikhiqizo yokunyathelisa kwe-Gravure
- Iveza imiphumela ephezulu ngokushesha
- Ihambisa ububanzi obugcwele bezindinganiso ze-tonal ezithombeni
- Kuhle kakhulu ukugijima isikhathi eside kakhulu
- Izigulisi zigcina izigidi zokuvela
I-Cons ye-Printing Printing
- Izindleko ziphakeme kunezinye izindlela zokunyathelisa
- Ukubamba akuyona imali ephumelelayo emisebenzini emifushane
- Izitolo ezimbalwa ezimbalwa zokuphrinta zihlose ukunyathelisa
Isithombe
Ukudweba isithombe kuyingqikithi yokunyathelisa kwendabuko yokuchithwa kwe-cylinder. I-photogravure isebenzisa izindlela zezithombe zokutshala izingcezu zethusi ezihlanganiswe ema-cylinders, kunokuba zihlanganise izilinda ngokwazo. Ngenxa yokuthi le nqubo engabizi kakhulu, ukuzitholela kufaka imali emfishane yokuphrinta okuphezulu futhi kuvame ukusetshenziswa ukukhiqiza ukudweba okuphezulu kwezinto zobuciko nobumnyama obufudumele kanye nobuningi bezinhlobonhlobo zembala.
Ifayela le-Digital Ukulungiselela Ukunyathelisa Ukuthunga
Nakuba izidingo zokulungiselela ifayela ledijithali yokunyathelisa okuqoshiwe zifana nezokuphrinta kwe-offset, abaklami abahlangabezana nale nqubo yokunyathelisa okokuqala kufanele baxhumane nesitolo sokuphrinta sokubhala noma yiziphi izidingo ezithile eziphathelene namafayela abo adijithali.
