Kuyini ukuphrinta kwe-rottogravaval?
Ukuphrinta okungaba buthaka ukwenza wonke umhlaba wepuleti lokuphrinta uhlanganiswe nok, bese usebenzisa indlela ekhethekile yokuklaba ukuze ususe inkinsi yengxenye ye-inki, bese kuthi inki idluliselwe ebusweni be-substrate, ukuthola lolu daba oluphrintiwe. Ukuphrinta okubangekele ukuphrinta okuqondile. Ingxenye yesithombe yepuleti yokuphrinta i-concave, futhi izinga lokuhlanza elinezinga lesithombe linemibala ehlukene, ingxenye engenalutho yepuleti yokuphrinta iyaphakanyiswa, nangendiza efanayo ye-cylinder.
Inqubo ye-rotgrovaval iyindlela yokudlulisa eqondile yokuphrinta kwi-Wood-pulp fiber based, zokwenziwa, noma ama-substrates, kufaka phakathi:
-Films ezinjenge-pet, opp, i-nylon, ne-pe, pvc, cellophane
-Iphapha
Ibhodi le -Carton
-Luminum foil
Inqubo yokuphrinta ye-rotogravisive
Ukuphrinta okujikelezayo ngenxa yezinga eliphakeme lokuzenzakalela komshini wokuphrinta, ikhwalithi yepuleti ilungile, futhi ngenxa yalokho ukusebenza kwenqubo kulula kunokuphrinta kwe-lithographic, kulula ukugeleza, ukugeleza kwenqubo kungokulandelayo:
Ukulungiselela Ukuphrinta kwangaphambili → kwipuleti lesilinda → Lungisa ukubhaliswa kombala → Ukuphrinta okusemthethweni → Ukucutshungulwa kwangemva kokucindezela
Inqubo yenqubo
Ngesikhathi senqubo yokuphrinta yeGrass Test Crylir Cylinder ijikeleza epanini le-INK lapho amaseli aqoshwe khona agcwalisa ngoyinki. Njengoba isilinda sijikeleza ngokucacile kwe-ink pan, noma yimuphi uyinki owedlulele asuswa ngudokotela blade. Ngaphezu kwalokho, isilinda sitholwa ne-substrate, ecindezelwa ngokumelene nayo ngerabha elimbozwe irabha.
Ingcindezi ye-roller, kanye ne-capillary drive ye-substrate, kuphumela ekudluliseni okuqondile kwe-ink kusuka kumaseli esilinda sokuphrinta ebusweni be-substrate. Njengoba umqulu wokuphrinta ujikeleza ubuyela epanini le-inki, indawo ephrintiwe ye-substrate iqhubeka nge-dryer nakuyunithi elandelayo yokuphrinta, okuvame ukuba ngumbala ohlukile noma kungaba yi-varnish noma i-coating.
Umbala oqondile wokubhalisa kombala wenziwa kwenzeke nge-othomatic side nasebude amasistimu wokulawula irejista.
Ngomshini wokuphrinta wewebhu, ngemuva kokuthi umbala ngamunye uphrintiwe futhi noma yiziphi izimbozo ezisetshenzisiwe, iwebhu 'iphindaphinde' ibe yiroli eqediwe.
Manje sigxile kwinqubo yokuphrinta ingathinta ngqo ikhwalithi yokuphrinta yenye yezixhumanisi ezibaluleke kakhulu - ukubhaliswa kombala
Kulezi zinsuku, iningi lemishini yokuphrinta yokuphrinta lizosebenzisa uhlelo lokubhalisa kombala oluzenzakalelayo lokubhaliswa kwephethini, okuthuthukisa kakhulu ukusebenza kahle kokubhalisa nekhwalithi yokuphrinta.
Emshini wokuphrinta wewebhu we-Web, kukhona idivaysi etholwayo efakiwe. Idivayisi iqukethe ikhanda lokuskena, i-generator ye-pulse, isilawuli se-elekthronikhi, imoto eguqukayo, i-roller eguqukayo ngokweqile nokunye.
Lapho uphawu olweqile ephepheni eliphrintiwe ngekhanda lokuthwebula, isibonakaliso se-pulse sizodluliselwa kumlawuli we-elekthronikhi, uma umbala wesibili wombala we-flevere, ukuze umlawuli wokuqala we-elekthronithi uzobe ungenacala, ukuze kube nombala wokuqala we-polpring phakathi kwenani eliphakeme lokuqondisa, ukuqeda amaphutha agqamile.
Ngaphezu kwalokho, kukhona nezinto ezilandelayo ezingathinta ikhwalithi nokusebenza kahle kokuphrinta, kepha sizoba nezixazululo ezifanele
a) t yena inki ayilingani ngombala
Umcimbi wombala we-inki ngezikhathi ezithile ushintsha izinto eziphrintiwe. Izindlela zokuqeda zibandakanya: Ukulungisa ukuzungeza kwesilinda sepuleti yokuphrinta, ukuguqula i-angle nengcindezi ye-squeegee noma ukufaka esikhundleni se-squeegee nge entsha.
b) Ama-FUZZY ne-Linty Prints
Amazinga wesithombe aphrintiwe kanye nezinga, nakekela, umkhathi wezimbumbulu onqenqemeni lwesithombe. Izindlela zokuqedwa zifaka phakathi: Ukususa ugesi we-Static kusuka ebusweni be-substrate, engeza izixazululo ze-polar ku-inki, ngokufanele ngokwandisa umfutho wokuphrinta, kanye nokushintsha isikhundla se-squeegee nokunye.
c) inguqulo evinjiwe
I-ink yomiswa endaweni yokuphrinta yepuleti, noma umgodi wepuleti lokuphrinta ugcwele izinwele zamaphepha, umgibeli wephepha le-powder, elibizwa ngokuthi ukuvimba. Izindlela zokuqedwa yilezi: Khulisa okuqukethwe kwama-solvents ku-inki, ukunciphisa ijubane lokomiswa kwe-ink, ukusetshenziswa kokuphrinta kwamaphepha okuqinisa indawo ephezulu.
d) inki spillage
Into ye-Spots ivela ensimini eprintiwe. Izindlela zokuqedwa zifaka phakathi: Ukungeza i-Hard Ink Ukuhlanganisa uwoyela, kuthuthukise ukubonakala koyinki. Lungisa i-angle ye-squeegee, khulisa ijubane lokuphrinta, bese ubuyisela ipuleti lokuphrinta elijulile ngepuleti lokuphrinta elingasho lutho.
e) ukuklanywa
Kukhona iminonjana ye-squeegee ekuphrintweni. Izindlela zokuqedwa yilezi: Sebenzisa uyinki ohlanzekile ngaphandle kwendaba yakwamanye amazwe exutshwe ekushicilelweni. Lungisa i-viscosity, ukoma nokunamathela ku-inki. Sebenzisa i-squeegee esezingeni eliphakeme, lungisa i-angle phakathi kwe-squeegee nepuleti lokuphrinta.
Onjiniyela be-Oyang's Design Design bahlaziya futhi balungiselele ukwakheka komshini ngokochungechunge lwezinkinga kwinqubo yokuphrinta, futhi yakhelwe i-Honor Sereis Rostog ROVURE SCHINE OFERICTION SOKUVIKELA KWABASEBENZA KWABASEBENZA abasebenzisi kanye nomkhakha.
I-RotgORAVURUCE PROPPORCEAL ANDATAGES kanye nezicelo
Le nqubo inikezela amandla okudlulisa inki ngokungaguquki, ngaphesheya kwezinhlobo eziningi, futhi ngejubane eliphezulu, okwenza kube lula ukuthola izicelo ezidinga ikhwalithi ephezulu, njengokuphrinta, ukuphrinta, ukuphrinta okuhlobisa.
Uhlobo oluhlala isikhathi eside lwama-cylinder wokuphrinta olusetshenzisiwe lwenza ukuphrinta ama-Glingabhula inqubo efanelekile yokunikeza ukuphrinta okuphezulu kakhulu noma okuphindaphindeke njalo, ukuletha izinzuzo zezindleko ngaphezu kwezinye izinqubo.
Ubuchwepheshe be-Oyang nolwazi
I-Innovator enamandla, egxile ekwakheni inani lamakhasimende ayo, imikhiqizo evela e-Oyang Rotcograval Press, ngeminyaka eminingi eChina, futhi inamafektri amakhasimende anochungechunge khona.
I-Innovator ehlaba umxhwele ngokulinganayo, u-Oyang usethe amazinga amasha ekuphrintiwe kwe-web-film ukuphrinta ezindaweni ezifunwayo ezifana nokushicilelwa okuguquguqukayo ngemishini yayo yochungechunge . Ukuthola imiphumela yokuphrinta evelele ekuphathweni okuguquguqukayo okuguquguqukayo kubeka izinselelo ezintsha zenqubo yokuphrinta evusa amangalisayo, kepha ukusetshenziswa kalula, isikhathi sokushintsha okusheshayo kanye nokuncishiswa kwemfucumfucu ye-Oyang kube yinye yezinketho eziphezulu zamakhasimende eChina nasemhlabeni jikelele.
