Ukuphrinta Izincwajana

Kuleli zwe lanamuhla, ukuthuthukiswa ubuchwepheshe ukuphrinta, ukuphrinta ezehlukene zinikeza nobukhulu bobubanzi bamasizo wokunyathelisa (izincwajana, izinhlu, amapheshana), sisebenzisa izindlela ezahlukahlukene ukunyathelisa futhi okwalandela ukuphrinta ukucutshungulwa mikhiqizo. Cabanga ngezindlela ezilula zokunyathelisa main esetshenziswa yokunyathelisa yesimanje, kanye ukuzwisiswa, okuthi umuntu kuyoba ngaphezulu engabizi for izincwajana, izincwajana amapheshana, kanti ezinye izincwadi, omagazini namaphephandaba. izindlela zokuhlola ezasungulwa zingahlukaniswa zibe ezintathu: Kwanyatheliswa ezijulile, flat futhi okusezingeni eliphezulu.
Gravure ukuphrinta ubuchwepheshe ingasetshenziswa ukwenziwa izincwajana ukukhangisa kunyatheliswa ezinkulu. izakhi Ukuphrinta ahlelwe ngezansi non. Lamafomu isithombe esibukweni, penda isikhala izinto ezimhlophe isuswe squeegee. Ukukhiqizwa yezincwajana ngale ndlela kulondoloza eliphezulu halftone, kodwa umbhalo encane kungaba komumo wobuso. ukuphrinta Ncwajana amapheshana indlela evelele uvame kwenziwa ngokuhlanganyela Kwanyatheliswa okusezingeni eliphezulu. Kulokhu, lesi sithombe ezinyatheliswe Gravure ukuphrinta, kanye nombhalo kuphezulu. Ububanzi Gravure ukuphrinta libanzi impela: iphepha lokunamathisela odongeni, izincwadi, izincwajana ezingangomagazini, izibambiso.
Usilika sesikrini wokunyathelisa (wokunyathelisa kwesikrini) wenziwa usebenzisa ukuphrinta ipuleti igridi ukuthi Ungaphrinta phezu ngokuphelele noma iyiphi ukuma. Ukuphrinta amapheshana nezincwajana, kulesi simo, isithombe umbala kuba ayegcwele ngenxa eningi udayi ungqimba. It is ezisetshenziswa kuzo zonke evele futhi bonke osayizi: ukukhiqizwa nezincwajana, ezikhangiso. Surface kungenzeka iphepha, indwangu, izinto ezenziwe ngobumba (amapuleti), ingilazi nokunye.
By wokunyathelisa kwesikrini kuthiwa wenziwa ngaphezulu Risograph umshini wokunyathelisa stencil nowokunyathelisa. Nale ndlela izakhi whitespace zidalwe avuthayo ezihlahla impahla zokunyathelisa. Isetshenziselwa ngokuvamile kakhulu amakhophi amadokhumende.
Lithography ekutholeni ukunyathelisa futhi okungezona ukuphrinta izakhi ezahlukene ezingeni elifanayo. ukuphrinta Flat sehlukaniswe nenkhulumombiko. Ongaqondile incwajana ukuphrinta is ibizwa kanjalo ngoba isithombe kusukela ipuleti wokunyathelisa e-Kwamanzi azenziwanga ngokuqondile, kodwa ngokusebenzisa eliphakathi nendawo (ingubo) isilinda. Le ndlela ethandwa kakhulu ezimweni eziningi, ukunyathelisa izincwadi ncwajana ukuphrinta is offset wenziwa eMoscow. Nokusakazwa ukukhangisa izinto, omagazini, amapheshana futhi benza offset (ngokungaqondile) zokunyathelisa.
Izindlela zokunyathelisa ngqo zihlanganisa lezo isithombe adluliselwe ipuleti wokunyathelisa e-impahla ngqo. It tipoofset, collotype, lithography futhi di-Litho.
Phototype inikeza sokuphrinta yezincwajana, amapheshana eliphezulu kakhulu izinga Okubonwayo. Ukwehlukanisa izakhi ukunyathelisa futhi liyatholakala ngokushayela whitespace zadublivaniya gelatin. Ngenxa ukudluliswa eliphezulu amathoni kanye nemibala, collotype ukuphrinta izithombe kanye tonkoshtrihovye imidwebo.
lithography indlela kuyaqabukela esetshenziswa namuhla, ikakhulukazi ngokwenza lalezi zincwajana ukuphrinta nezincwajana. Ukuze afeze ungeno ekubhaleni ukuphrinta ipuleti owadalwa flat itshe lithography. Isetshenziswa ngesikhathi esifanayo ne-aluminiyamu flat axutshwe nepulasitiki nopende viscous. Izithombe high kakhulu. Lapho esetshenziswa tipoofsete isilinda ingubo kanye nefomu zokunyathelisa. Tipoofsetnaya anyathelisiwe bafake ngaphezulu ukumelana futhi ayidingi humidification, okuvumela ukuphrinta ku ezihlukahlukene izinto.
Ngu izindlela flat ukuphrinta futhi zihlanganisa electrophotography futhi MAGNETOGRAPHY. Ngo copiers (Xerox) kanye laser amaphrinta nje isicelo electrophotography. Lolu hlobo ukuphrinta kuyinto zithandwa kulezizinsuku abantu abaningi esetshenziswa ukwenziwa izincwajana yokukhangisa, izincwadi, amapheshana. Electrophotography evame ukusetshenziswa yizinkampani nokunikeza ngamasevisi ukunyatheliswa digital okusheshayo, ukunyatheliswa izincwajana, amapheshana, izincwajana.
Ngo zamagama izakhi ukuphrinta ahlelwe ngendlela isikhala esimhlophe ngenhla. Lena ngenye yezindlela endala yokunyathelisa. Izincwadi zokuqala ezanyatheliswa zamagama zokunyathelisa. indlela elula futhi enokwethenjelwa esetshenziswa namuhla ngoba uyinki sokunyathelisa embossing. Lapho wayala, ukunyathelisa incwajana, kubalulekile ukukhumbula ukuthi le ndlela Kwenziwa ezinombala ofanayo ukuphrinta kuphela, angasetshenziswa anyathelisa amaphephandaba, omagazini, izincwajana kanye neminye imikhiqizo ezinyathelisiwe, lapho kungekho isidingo elikhazimulayo esigcwele umbala izithombe.
Flexography libhekisela izindlela zokunyathelisa. Lokhu ukuphrinta usebenzisa ukuphrinta ipuleti nezimo lapho ogibele amasilinda ipuleti diameters ezahlukene. Lokhu kukuvumela ukuba sisebenzise zeJiyomethri, amaphethini, ngaphandle kokuphazamisa ukunyatheliswa nezincwajana ngesivinini. Indaba ukuba kunyatheliswe - iphepha, amakhadibhodi, Indwangu polymeric. Ububanzi flexographic lalezi zincwajana ukuphrinta izincwajana, iphepha lokunamathisela odongeni, amalebula kanye emaphaketheni.
Izindleko yezincwajana ukuphrinta
Ukwenza i-oda ncwajana ukuphrinta, kufanele ucabangele izindleko kanye nohlobo ukuphrinta. Izindleko zokunyathelisa izincwajana incike indlela ekhethiwe ukunyathelisa futhi kunyatheliswa amakhophi nezincwajana.
Ngu Gravure kudingekile iphendukele, uma ukuzungeza kuyinto amakhophi abangamakhulu ezinkulungwane eziningana. Kungenjalo - ke kuyabiza kakhulu.
izincwajana yokukhiqiza izindleko zokunyathelisa nge-offset kuzuzisa kakhulu lapho mnogotirazhevom oda. yokunyathelisa ye-offset kuyinto ephakeme kakhulu izinga engabizi indlela ukuphrinta. Kodwa wangaphambi kokunyathelisa kwandisa izindleko oda. Ngisho ukusakazwa nsuku ungathola eqolo.
