Indlela yokwenza ipuleti ye-Gravure yomshini wokuphrinta we-rotogravure

Umshini wokuphrinta we-Rotogravurei-engraving gravure i-gravure eyenziwe ngokuqoshwa ngesandla noma ngomshini, futhi kuyinqubo yokuqala yokwenza amapuleti ekuphrinteni komshini wokuphrinta we-Rotogravure.Njengamanje, umshini wokuphrinta we-Rotogravure wendabuko wokuqopha i-gravure awuvamile ukusetshenziswa, kanti i-electronic engraving gravure iyipuleti lokuphrinta elisetshenziswa kakhulu emkhakheni wokuphrinta i-gravure.Okulandelayo, ake sibheke indlela yokwenza ipuleti ye-gravure yomshini wokuphrinta we-Rotogravure ngeJINYI

1. Umshini wokuphrinta we-RotogravureUkudweba amapulangwe ngesandla

Umshini wokuphrinta we-RotogravureIndlela yokuqopha ye-Gravure plate-making manual ingahlukaniswa ngezinhlobo ezimbili: indlela yokuqopha kanye nendlela yokufaka.Endleleni yokuqopha umshini wokunyathelisa we-Rotogravure, i-gravure eqoshiwe eqondile iqoshwe ngesandla ngommese oqoshiwe, futhi ipuleti yasekuqaleni ye-gravure yesithombe yenziwa ngokuqondile;Indlela yokuqopha umshini wokunyathelisa we-Rotogravure iyindlela yokwenza ngokuqondile ipuleti le-gravure ngokugingqa epuletini elinethuluzi lokuqopha njengefosholo lokugqamisa nokwenza umfaniswano we-concave ocolekileyo kanye ne-grit ye-convex endaweni yepuleti ukuze kusetshenziswe ipuleti le-shading.Ipuleti le-intaglio eligxilile endleleni yokunamathisela umshini wokuphrinta we-Rotogravure ukumboza ungqimba lwefilimu evimbela ukugqwala epuleti lensimbi, uliqophe ngokwenza inaliti yokucwilisa, ushume ifilimu evimbela ukugqwala, futhi uthole isithombe nombhalo ngokuqoshwa kwamakhemikhali. indlela.I-gravure yomugqa, engaphrinta amathoni athambile;Indlela yokunamathisela umshini wokunyathelisa we-Rotogravure iwuhlobo lwe-etching gravure, epuletini eliphansi, ngezindlela zemishini nezandla, ukufafaza i-resin noma i-asphalt powder, nokushisa ukulungisa i-powder Epuletini, isithombe esibi sibe sesiqoshwa nge-resista, futhi i-gravure yesithombe yenziwa ngendlela yokuqopha.

Isithombe esingesihle, i-gravure yesithombe eyenziwe ngendlela ye-etching.

2. Umshini wokuphrinta we-Rotogravure Ukwenza ipuleti lokuqopha nge-elekthronikhi

Umshini wokuphrinta we-RotogravureAmasu okuqoshwa kwe-Electromechanical kuyinqubo yokuguqula amasignali abonakalayo noma edijithali abe ukunyakaza kwemishini ngokuguqulwa kwesithombe kagesi (ukuguqulwa kwedijithali-kuya-analog) nokuguqulwa kwe-electromagnetic.Ijeneretha yefrikhwensi isetshenziselwa ukukhiqiza i-oscillation ngefrikhwensi ethile (4-8kHz) kanye ne-amplitude efanelekile.Ngemuva kokuthi isignali yedijithali yememori yesithombe iguqulwe ibe isignali ye-analog ngesiguquli se-digital-to-analog, ihlanganiswa ne-amplitude yento yangaphambilini ukulawula ummese oqoshiwe ukuze ujikeleze ngesivinini esingaguquki.Ingaphezulu le-plate-making layer yethusi ye-plate roller iqoshwe ngamaseli anobukhulu obuhlukene nokujula.Umshini wokuphrinta we-Rotogravure Umgomo wokwenza ipuleti le-electronic engraving gravure ukuthi umshini wokuqopha we-elekthronikhi ungakwazi ukulawula kahle inani elidingekayo lemigqa yesikrini kanye ne-angle yesikrini ngokulawula isivinini sokujikeleza kwesigubhu kanye nesivinini sokuphakela kwe-lateral sekhanda eliqoshiwe ukuze lihambisane nomdwebo. imvamisa.

Ukwenziwa kwepuleti lokuqopha nge-elekthronikhi yilapho umshini wokunyathelisa we-Rotogravure womshini wokuqopha i-electronic uqopha ngokuqondile ukwakhiwa kwamapuleti esigubhu ngokolwazi lwedijithali olukhiqizwa uhlelo lokushicilela lwedeskithophu enemibala.Isimiso sokusebenza somshini wedijithali womshini wokuqopha we-elekthronikhi womshini ohlelweni lokuqopha lwe-elekthronikhi olungenafilimu: Umshini wokunyathelisa we-Rotogravure ongenafilimu owenziwe ngepuleti lombhalo we-elekthronikhi ungowokuqala ukuqaphela ngokugcwele ubuchwepheshe be-CTP kuzo zonke izinqubo zokwenza amapuleti okuphrinta.Umshini wokuphrinta we-Rotogravure inqubo yokwenza ipuleti lombhalo oqoshiwe we-elekthronikhi ongenafilimu: ukwakheka kwekhasi ledijithali → ukulungiselelwa kwepharamitha → ukudweba kwesilingo → ukuqoshwa okusemthethweni.

Ukubekwa: Endaweni yokusebenza yokufaka, ngokuya ngezidingo zokuphrinta umshini wokuphrinta we-Rotogravure, amakhasi eyunithi acindezelwe ngaphambili aqoqwa abe amafomethi amakhulu ukuze aqoshwe ngokuya ngesakhiwo, futhi ngasikhathi sinye, ukulawula inqubo yangemuva. isilawuli sibekwe esakhiweni esihlanganisiwe.umaka.Amamaki okulawula ikakhulukazi afaka amamaki okubhalisa okulawula ukuphrinta ngokweqile okunembile, amamaki okusika okulawula ukusikwa komshini wokuphrinta we-Rotogravure, njll.

Ukulungiselelwa kwepharamitha: Setha ijika lezinga lokuqopha, umugqa we-mesh, i-mesh angle, njll. endaweni yokusebenza yokulawula ukuqoshwa komshini kagesi emshinini wokuphrinta we-Rotogravure.

Umbhalo wesilingo: Inhloso iwukuba ulungise umshini wamanje oqoshiwe womshini wokunyathelisa we-Rotogravure (setha i-amplitude, ukukhanya okuphezulu kwamanje kanye nobumnyama bokulungisa okwamanje), ukuze ithoni emnyama eqoshiwe, ukukhanya okuphezulu, nokuxhumana kuhlangabezane nezidingo zenqubo.

Ukuqoshwa okuhlelekile: Ngemva kokuba umshini wamanje oqoshiwe ulungiswe ube nenani elifanele ngemva kokuqoshwa kokuhlolwa komshini wokunyathelisa we-Rotogravure, indawo yokuqala yokuqopha ingasethwa futhi kuqalwe ukuqoshwa okusemthethweni.

3. Umshini wokuphrinta we-Rotogravure Ubuchwepheshe bokuqopha nge-elekthronikhi obucwebezelayo be-Ultra-fine

Ngaphezu kwamasu amabili omshini wokuphrinta we-Rotogravure we-electro-engraving echazwe ngenhla, entshaUmshini wokuphrinta we-Rotogravurei-electronic engraving technique itholakele: I-XT (Xtreme Engraving) i-ultra-fine electronic engraving technique.Ubuchwepheshe be-XT Ultra Fine Electronic Engraving busebenzisa umbhalo onokucaca okuphezulu oqoshiwe kanye nezici zesithombe esihle.Umshini wokuphrinta we-Rotogravure usebenzisa ubuchwepheshe bokuqopha nge-elekthronikhi be-XT be-ultra-fine.Ngokwesisekelo sokuthi ikhanda lokuqopha lihlala lingashintshiwe, ukulungiswa okuqoshiwe kwemishini evamile yokudweba nge-elekthronikhi kwanda kumigqa engu-200 / cm;kanye nemishini yokuqopha ye-elekthronikhi esetshenziswa emkhakheni wezokuphepha, ukuthuthukiswa okukhethekile kungamukelwa.Ikhanda lokuqopha likhulisa ukuqoshwa kwalo libe yimigqa engu-2000/cm.Umshini wokuphrinta we-Rotogravure Ubuchwepheshe bokudweba nge-elekthronikhi be-ultra-fine budinga isilawuli sesikrini, esibekwe ekhanda eliqoshiwe le-XT, futhi isikrini siqoshwe ngesikhathi esifanayo.Ingqamuzana elilodwa lombhalo oqoshiwe lakhiwe imigqa eminingi yokuqoshwa.Inombolo yemigqa yeseli eqoshiwe iyafana nesinqumo sokuqoshwa singahluka.Isiginali yokuqopha enokulungiswa okuphezulu komugqa ngamunye kufanele ibe nesibopho sokwenza ikhontayutha engaphakathi yekhonkolo.Umumo wokuvuleka kweseli owenziwe inhlanganisela yemigqa eminingi yokuqoshwa nawo udinga ukunqunywa idatha eqoshiwe.Ngaphansi kokulawulwa kwedatha ye-grayscale ecutshunguliwe, amaseli anama-engeli esikrini ahlukene kanye nokuvuleka komumo angenziwa ngokukhululeka kakhudlwana, futhi ngisho nokuhlolwa kokumojula imvamisa kungenziwa ngenxa yokuthi umumo weseli ne-engeli kukhululwa emikhawulweni “yeseli elilodwa ngesikhathi. ” indlela.ukucutshungulwa, futhi ekugcineni uthole ukukhiqizwa kabusha kwesikrini se-FM.

Okungenhla konke okuqukethwe komshini wokuphrinta we-Rotogravure wendlela yokwenza amapuleti alethwe kuwe namuhlaJINYI.Ngikholwa ukuthi ngemva kokufunda wonke umbhalo, wonke umuntu unokuqonda okuthile kwendlela yokuqopha amapuleti e-gravure, indlela yokwenza ipuleti lokudweba nge-elekthronikhi kanye nobuchwepheshe bokuqopha obucwebe kakhulu be-elekthronikhi, kanye nolunye ulwazi oluthe xaxa lubuyekezwa ngokuqhubekayo, sizokubona kumagazini olandelayo.
