Ngemuva kweminyaka engama-40 yentuthuko, iChina isibe ngumkhiqizi nomthengi omkhulu emhlabeni wonke embonini yamalebula. Ukusetshenziswa kwamalebula ngonyaka cishe kungama-square metres ayizigidi eziyizinkulungwane eziyi-16, cishe ingxenye yesine yesamba esisetshenziswa amalebula emhlabeni jikelele. Phakathi kwazo, ukusetshenziswa kwamalebula azinamathiselayo kubala ngaphezu kwengxenye eyodwa kwezintathu yokusetshenziswa kwamalebula eChina, okuyizikwele zamamitha ayizigidi eziyizinkulungwane eziyisi-6 kuya kwezingu-7, kanti amanye amalebula ephepha, amalebula efilimu ashwabene, amalebula asesikhunjeni namalebula emikhono.
Ukuphrinta ilebula yamaShayina, ikakhulukazi ukuzi-adukuphrinta ilebula elukhuni, kuthonywa kakhulu iJapan. Njengamanje, i-letterpress printing akhawunti ilinganiselwa ku-60%, kuseyinsika yemboni yokunyathelisa yamalebula; Ama-akhawunti wokuphrinta asethiwe cishe angama-20% futhi ayindlela yokuphrinta ekhula ngokushesha kakhulu; Ama-akhawunti wokuphrinta we-Flexography angaba ngu-10%, iyindlela ekahle kakhulu yokunyathelisa, kodwa ethintekayo yizici ezihlukahlukene e-China, okwamanje ifakwe ngobuningi, i-boot encane. Enye i-10% ukuphrinta kwedijithali nezinye izindlela zokuphrinta njengokuphrinta isikrini, ukuphrinta kwegravure nokuphrinta okukhethekile.
Ukuphrinta kwedijithali ubuchwepheshe obuthuthuka ngokushesha emkhakheni wokuphrinta ilebula. Ngokuvamile, ukuphrinta kwedijithali kusebenzisa i-inkjet, i-toner, i-electronic ink kanye nezindlela zokudlulisa inkjet.
Okugqama kakhulu ukuphrinta okuyinhlanganisela, okuhlanganisa ukuphrinta kwedijithali nokuphrinta kwendabuko.
2. Ukuphrinta imibala eyisikhombisa
Ukuphrinta kwemibala eyisikhombisa, okwaziwa nangokuthi "ukuphrinta okuthembekile", kwandisa i-gamut yombala futhi kuthuthukisa kakhulu ikhwalithi yombala wendaba ephrintiwe. Ukusebenzisa inkambu yokunyathelisa imbondela yamachashazi esikhundleni senkambu yokunyathelisa ye-inki yombala ekhethekile, asikho isidingo sokumisa uyinki wombala okhethekile, ukunciphisa ukusetshenziswa kwempahla kanye nezindleko; Uma iphrinta iphrinta ama-oda amaningi, idinga kuphela ukushintsha ipuleti ngaphandle kokuhlanza amacansi nokushintsha uyinki, okuthuthukisa ukusebenza kahle kokukhiqiza.
3. Ukuphrinta kwe-offset okungenamanzi
Isebenzisa u-inki wokudlulisa ophansi, osetshenziswa kumishini yokudlulisa uyinki yerola, i-viscosity ye-inki kanye nomehluko wombala wokuphrinta ungalungiswa ngokungahleliwe, umbala wokuphrinta uhambisane, ukusebenza kahle kokuphrinta okuphezulu, izikhathi ezi-2 ~ 3 zemishini yokuphrinta ilebula yendabuko.
I-Flexography iwuhlobo lokunyathelisa olusebenzisa amapuleti e-flexo futhi ludlulise uyinki nge-anilox roller. Ipuleti lokuphrinta le-Flexographic ngokuvamile lisebenzisa ukujiya kwepuleti le-photosensitive resin elingu-1-5mm. Uyinki uhlukaniswe izigaba ezintathu, ngokulandelana uyinki osuselwe emanzini, uyinki oncibilika ngotshwala, uyinki ye-UV. NjengobaUyinki wokuphrinta we-flexographic uluhlaza, iye yasetshenziswa kabanzi ekunyatheliseni amaphakheji okudla futhi inamathemba abanzi.
Ilebula ye-PS yokuphrinta ipuleti le-self-adhesive inezindleko eziphansi zokwenza ipuleti le-offset kanye nomphumela omuhle wokuphrinta, umshini welebula le-offset ukukhetha kokuqala kwamabhizinisi okuphrinta ilebula ngaphezu komshini we-letterpress wendabuko. Ukuphrinta kwe-Offset kwenza ukukhubazeka kwezithombe ze-letterpress, izindleko zokwenziwa kwamapuleti ziphansi, zilungele zonke izinhlobo zama-oda, zamukelwe amabhizinisi okuphrinta ilebula.
Isici esikhulu kunazo zonke se-letterpress sifushane, siyisicaba, siyashesha, amabhizinisi anyathelisayo angakwazi ukuzenzela ipuleti lawo, uyinki wokuphrinta, umphumela omuhle weshalofu, ukusebenza okulula, ukulungisa okulula, okufanelekile kuzo zonke izinhlobo zemikhiqizo yelebula ephakathi.
Umshini we-Letterpress uhlukaniswe ikakhulukazi izigaba ezimbili: owodwa umshini we-rotary letterpress uhhafu, owaziwa ngokuthi umshini we-letterpress intermittent; Enye i-full rotary letterpress. Nakuba ukuphrinta ilebula ye-letterpress kungakaze kubonwe emabhizinisini okunyathelisa ilebula ephezulu e-China, Kusengamandla amakhulu okuphrinta ilebula ezinamathelayo emabhizinisini okuphrinta amalebula amancane naphakathi nendawo, okubalelwa ku-60%, futhi lesi simo ngeke sishintshe esikhathini esifushane.
Ukuphrinta okuhlanganisiwe ukufeza izindlela zokuphrinta eziningana ezihlukene kudivayisi eyodwa, engafinyelelwa ngokuvamile emishinini yokunyathelisa ye-flexography,
Ukuphrinta kwenhlanganisela yendabuko ngokuvamile kusekelwe ekuhlanganiseni kokunyathelisa kwe-flexography, uma kunesidingo, engeza isitembu esibandayo, ukuphrinta kwesikrini, isinyathelo esisodwa sokuqedela ukuphrinta. Ukuphrinta okuhlanganisiwe ngokomqondo wesimanje kuyinhlanganisela yokuphrinta kwedijithali nokuphrinta kwendabuko, okungukuthi, ilebula inayo kokubili ukuphrinta kwendabuko kanye nokuphrinta kwedijithali okunokuqukethwe okuguquguqukayo, okwenza umugqa wokukhiqiza wokuphrinta idatha oguquguqukayo.
8. I-CTP : ikhompuyutha-kuya-epuletini
Indlela yokuthuthukiswa kobuchwepheshe bokuphrinta i-digitalization, futhi i-digitalization iqala kusukela ekunyatheliseni kwangaphambili. Imboni yelebula iye yaqaphela ngokuyisisekelo i-CTP plate making in flexography and offset printing, kodwa izinga lokungena kwe-CTP plate making in letterpress lilinganiselwa ku-10% kuphela, futhi imboni yelebula yaseChina ngokuyinhloko i-letterpress, ngakho-ke ukwenza amapuleti e-CTP kunemakethe enkulu engaba khona embonini yamalebula.
9. Impahla yelebula engaphakathi kwesikhunta
Ilebula ye-in-mold ingenye yemikhiqizo ethuthuka ngokushesha ochungechungeni lwemboni yamalebula ekhaya naphesheya. Inomlando weminyaka ecishe ibe ngu-30 eChina. Inezici ezimbili: okokuqala, inomphumela omuhle wokuhlobisa futhi i-caviar ku-general emndenini welebula; Okwesibili, ngenxa yokuthi alikho iphepha lesisekelo, ungqimba kuphela lwefilimu, ilebula ingaphinda isetshenziswe ngesitsha, ngakho izici zokuvikela imvelo zinhle. Ilebula elingaphakathi kwesikhunta liphinde libe indlela yokuhlobisa etuswa imboni yamazwe ngamazwe yokupakisha nokunyathelisa. Ihlukaniswe yaba izigaba ezimbili: ukubumba igalelo kanye nokubumba umjovo.
