Isingeniso Senqubo Yokuphrinta ye-Rotogravure

Kuyini ukuphrinta kwe-rotogravure?

Ukuphrinta kwe-Gravure ukwenza yonke indawo yepuleti yokunyathelisa ehlanganiswe ngoyinki, bese usebenzisa indlela ekhethekile yokukhuhla ukuze ususe uyinki engxenyeni engenalutho kayinki, ukuze uyinki ufakwe kuphela emigodini ye-mesh yengxenye yesithombe sikayinki, bese kuthi ngaphansi kwesenzo sokucindezela okukhulu, uyinki uzodluliselwa endaweni engaphansi, endaweni yokuphrinta. Ukuphrinta kwe-Gravure ukuphrinta okuqondile. Ingxenye yesithombe sepuleti yokuphrinta i-concave, futhi izinga lokugoba ngezinga lesithombe linemithunzi ehlukene, ingxenye engenalutho yepuleti yokunyathelisa iphakanyiswa, futhi endizeni yesilinda efanayo.

Inqubo ye-rotogravure iyindlela yokudlulisa eqondile yokuphrinta ku-wood-pulp fiber based, synthetic, noma laminated substrates, okuhlanganisa:

-Amafilimu afana ne-PET, i-OPP, inayiloni, ne-PE, i-PVC, i-Cellophane

— Amaphepha

—Ibhodi lebhokisi

- I-aluminium foil

Inqubo yokuphrinta ye-Rotogravure

Ukuphrinta kwe-Rotogravure ngenxa yezinga eliphezulu lokuzenzakalela komshini wokunyathelisa, izinga lepuleti lihle, futhi ngaleyo ndlela ukusebenza kwenqubo kulula kunokuphrinta kwe-lithographic, kulula ukuyiqonda, ukugeleza kwenqubo kanje:

Ukulungiselela ukuphrinta kwangaphambili → ku-cylinder plate → lungisa ukubhaliswa kombala → ukuphrinta okusemthethweni → ukucubungula ngemva kokucindezela

Incazelo yenqubo

Ngesikhathi sokuphrinta i-gravure isilinda sokuphrinta sizungeza epanini likayinki lapho amaseli aqoshiwe agcwalisa uyinki. Njengoba isilinda sizungeza kucace epanini likayinki, noma yimuphi uyinki oweqile ususwa yi-blade kadokotela. Ngokuqhubekayo, isilinda sihlanganiswa ne-substrate, ecindezelwa ngokumelene nayo yi-roller embozwe yirabha.

Ukucindezela kwe-roller, kanye nomdwebo we-capillary we-substrate, kubangela ukudluliselwa okuqondile kukayinki kusuka kumaseli kusilinda sokuphrinta kuya ebusweni be-substrate. Njengoba i-roller yokunyathelisa izungeza ibuyele epanini likayinki, indawo ephrintiwe ye-substrate idlulela esomisini bese ingena eyunithi yokuphrinta elandelayo, evame ukuba nombala ohlukile noma okungenzeka kube ukuvanisha noma ukunamathela.

Umbala oqondile wokubhaliswa kombala wenziwa ukuba kwenzeke ngokusebenzisa amasistimu okulawula amarejista ohlangothi nobude obuzenzakalelayo.

Emshinini wokunyathelisa oxhaswe ngewebhu, ngemva kokuba umbala ngamunye usuphrintiwe futhi kwasetshenziswa noma yiziphi izimbotshana, iwebhu 'iphinde ihlanganiswe' ibe umqulu oqediwe.

Manje sigxila enqubweni yokuphrinta ingathinta ngqo ikhwalithi yokunyathelisa yezixhumanisi ezibaluleke kakhulu - ukubhaliswa kombala

Namuhla, iningi lemishini yokuphrinta i-gravure izosebenzisa isistimu yokubhaliswa kombala okuzenzakalelayo ukubhaliswa kwephethini, okuthuthukisa kakhulu ukusebenza kahle kokubhalisa kanye nekhwalithi yokuphrinta.

Emshinini wokuphrinta we-web gravure, kukhona idivayisi yokuphrinta ngokweqile okuzenzakalelayo efakiwe. Idivayisi iqukethe ikhanda lokuskena, i-pulse generator, isilawuli se-electronic, i-motor elungisayo, i-overprint adjusting roller njalonjalo.

Lapho uphawu lwe-overprint eshidini eliphrintiwe ngekhanda lokuskena, isignali ye-pulse izodluliselwa kusilawuli se-electronic, uma umbala wesibili we-overprint mark ungalungile ngaphambi noma ngemva kombala wokuqala wophawu, ukuvela kwesikhathi se-pulse kuzobe kungalingani, ngakho isilawuli se-elekthronikhi sizoqala ukulawula injini, ukuze umbala wokuqala kanye nombala wesibili we-overprint obala ube nephutha elincane elilawulayo phakathi kwama-overprints alawulayo.

Ngaphezu kwalokho, kunezici ezilandelayo ezingathinta izinga nokusebenza kahle kokuphrinta, kodwa sizoba nezixazululo ezifanele.

a) Uyinki akalingani ngombala

Isimo sokushintsha kombala we-inki ngezikhathi ezithile ezintweni eziphrintiwe. Izindlela zokuqeda zihlanganisa: ukulungisa ukujikeleza kwesilinda sepuleti lokuphrinta, ukulungisa i-angle nokucindezela kwe-squeegee noma ukufaka esikhundleni esisha.

b) Imidwebo engaqondakali kanye ne-linty

Amaleveli esithombe esiphrintiwe kanye nezinga, ukunamathisela, isenzakalo sama-burrs onqenqemeni lwesithombe. Izindlela zokuqeda zihlanganisa: ukususa ugesi we-static ebusweni be-substrate, ukwengeza ama-solvents e-polar kuyinki, ukwandisa ngokufanele ukucindezela kokunyathelisa, nokulungisa isikhundla se-squeegee nokunye.

c) inguqulo evinjiwe

Ukomiswa kukayinki kumeshi yepuleti lokuphrinta, noma imbobo yeplate yokunyathelisa enezikhala igcwaliswa izinwele zephepha, into yempushana yephepha, ebizwa ngokuthi ukuvimba. Izindlela zokuqeda yilezi: ukwandisa okuqukethwe kwezincibilikisi kuyinki, ukunciphisa ijubane lokumisa uyinki, ukusetshenziswa kokunyathelisa kwephepha eliphezulu lamandla aphezulu.

d) Ukuchitheka kukayinki

Isimo samachashazi avela engxenyeni yensimu yokuphrinta. Izindlela zokuqeda zihlanganisa: ukwengeza amafutha okuxuba inki eqinile, ukuthuthukisa i-viscosity ye-inki. Lungisa i-engeli ye-squeegee, ukhuphule isivinini sokuphrinta, futhi esikhundleni sepuleti lokuphrinta le-deep-cavity ufake ipuleti lokuphrinta elingashoni.

e) Ukuklwebha

Kukhona imikhondo ye-squeegee ekuphrintiwe. Izindlela zokuqeda yilezi: sebenzisa uyinki ohlanzekile ngaphandle kwezinto zangaphandle ezixutshwe ekuphrinteni. Lungisa i-viscosity, ukoma nokunamathela kweyinki. Sebenzisa i-squeegee yekhwalithi ephezulu, lungisa i-engeli phakathi kwe-squeegee nepuleti lokuphrinta.

Onjiniyela bokuklama be-OYANG bahlaziya futhi bathuthukisa ukwakheka komshini ngokuvumelana nochungechunge lwezinkinga enqubweni yokunyathelisa, futhi baklama Umshini Wokuphrinta we-Honor Sereis ELS Rotog ravure ngokombono wokuxazulula amaphuzu obuhlungu wabasebenzisi kanye nemboni.

Izinzuzo ze-Rotogravure Process kanye nezicelo

Le nqubo inikezela ngekhono lokudlulisa uyinki ngokungaguquki, phakathi kwebanga elibanzi lokuminyana, nangesivinini esikhulu, iyenze ifaneleke izinhlelo zokusebenza ezidinga ikhwalithi yesithombe ephezulu, njengokushicilela, ukupakisha, amalebula, ukuphrinta kokuvikela, nokuphrinta kokuhlobisa.

Imvelo eqinile yamasilinda okuphrinta asetshenzisiwe yenza ukuphrinta kwe-gravure kube inqubo ekahle yokunikeza ukuphrinta kwekhwalithi ephezulu kuma-run amade kakhulu noma aphindaphindayo, okuletha izinzuzo zezindleko ngaphezu kwezinye izinqubo.

OYANG ubuchwepheshe nolwazi

Umsunguli owesabekayo, ogxile ekudaleni inani lamakhasimende akhe, imikhiqizo evela emshinini wokunyathelisa we-OYANG Rotogravure, Eminyakeni emithathu nje umshini we-OYANG Rotogravure uzakhele idumela elihle negama elihle e-China, futhi maningi amazwe nezifunda emhlabeni jikelele lapho amafekthri amakhasimende anochungechunge lwethu lwe-Honor electronic shaft rotogravure imishini yokunyathelisa ngokuzinza, futhi asebenza ngokuzinzile.

Umsunguli ohlaba umxhwele ngokulinganayo, u-OYANG usethe izindinganiso ezintsha ekuphrinteni kwe-web-film gravure ezindaweni ezifunwa kakhulu ezifana nokupakishwa okuguquguqukayo ngomshini wayo wokunyathelisa we-Honor® series rotogravure . Ukuthola imiphumela evelele yokuphrinta ekufakweni okuphezulu okuguquguqukayo okune-laminated kubangela izinselele ezintsha zenqubo yokuphrinta i-gravure, kodwa intuthuko yezobuchwepheshe, ukusetshenziswa kalula, isikhathi sokushintsha ngokushesha kanye nokuncishiswa kokumosha imishini ye-OYANG kubenza kube ngenye yezinketho eziphezulu kumakhasimende e-China nasemhlabeni jikelele.
