Ukuphrinta kwe-UV

Eminyakeni yamuva nje, izindlela zokunyathelisa ziye zathuthuka kakhulu. Enye intuthuko ephawulekayo ukunyathelisa nge-UV, okuncike ekukhanyeni kwe-ultraviolet ukuze kulungiswe uyinki. Namuhla, ukunyathelisa nge-UV kufinyeleleka kalula njengoba izinkampani zokunyathelisa ezithuthukayo zifaka ubuchwepheshe be-UV. Ukunyathelisa nge-UV kunikeza izinzuzo ezahlukahlukene, kusukela ekwandeni kwezinhlobo ze-substrate kuya ekwehleni kwezikhathi zokukhiqiza.

Ubuchwepheshe be-UV

Njengoba igama layo lisho, ukuphrinta kwe-UV kuncike kubuchwepheshe be-ultraviolet ukuze kulungiswe cishe ngokushesha i-inki. Nakuba inqubo yangempela ifana nokuphrinta okuvamile kwe-offset, kunemehluko omkhulu ohilela i-inki ngokwayo, kanye nendlela yokuyomisa.

Ukuphrinta okuvamile kwe-offset kusebenzisa uyinki wendabuko osuselwa ku-solvent owoma kancane ngokuhwamuka, okuwanikeza isikhathi sokumunca ephepheni. Inqubo yokumunca yisona sizathu esenza imibala ingakhanyi kakhulu. Abaphrinta babhekisela kulokhu njengomhlane owomile futhi babonakala kakhulu ezitokisini ezingamboziwe.

Inqubo yokunyathelisa i-UV ihilela o-inki abakhethekile abakhelwe ukomisa nokupholisa lapho bechayeka emithonjeni yokukhanya kwe-ultraviolet ngaphakathi komshini wokunyathelisa. O-inki be-UV bangaba nesibindi futhi bagqame kakhulu kuno-inki abavamile be-offset ngoba cishe akukho umhlane owomile. Uma sebephrintiwe, amashidi afika ku-delivery stacker elungele ukusebenza okulandelayo. Lokhu kuphumela ekusebenzeni kahle kakhulu futhi ngokuvamile kungathuthukisa izikhathi zokuguqula, ngemigqa ehlanzekile kanye namathuba amancane okufiphaza.
Izinzuzo Zokuphrinta Nge-UV

Uhlu Olubanzi Lwezinto Zokuphrinta

Iphepha lokwenziwa livame ukusetshenziswa emikhiqizweni edinga izinto ezingamelani nomswakama zokupakisha nokulebula. Ngenxa yokuthi iphepha lokwenziwa kanye namapulasitiki amelana nokumuncwa, ukuphrinta okuvamile kwe-offset kudinga isikhathi eside kakhulu sokoma. Ngenxa yenqubo yako yokomisa ngokushesha, ukuphrinta kwe-UV kungamukela izinto eziningi ezivame ukungafaneleki kuma-inki avamile. Manje sesingakwazi ukuphrinta kalula ephepheni lokwenziwa, kanye namapulasitiki. Lokhu kusiza futhi ngokugcotshwa noma ukufiphazwa okungenzeka, okuqinisekisa umklamo oqinile ongenamaphutha.

Ukuqina Okukhulisiwe

Uma kunyatheliswa nge-offset evamile, amaphosta e-CMYK, isibonelo, imibala efana nophuzi kanye ne-magenta yayivame ukunyamalala ngemva kokuchayeka isikhathi eside elangeni. Lokhu kungabangela ukuthi iphosta ibukeke njengethoni emnyama ne-cyan duo, naphezu kokuthi ekuqaleni yayinombala ogcwele. Amaphosta neminye imikhiqizo evezwe elangeni manje ivikelwe yi-inki elashwa umthombo wokukhanya we-ultraviolet. Umphumela uba umkhiqizo ohlala isikhathi eside futhi omelana nokunyamalala owenzelwe ukuhlala isikhathi eside kunezinto eziphrintiwe zendabuko.

Ukuphrinta Okunobungani Nemvelo

Ukuphrinta kwe-UV nakho kuyavumelana nemvelo. Ama-inki okuphrinta kwe-UV awaqukethe ubuthi obuyingozi, ngokungafani namanye ama-inki endabuko. Lokhu kunciphisa ingozi yokukhipha ama-compounds e-volatible organic (ama-VOC) ngesikhathi sokuhwamuka. Kwa-Premier Print Group, sihlala sifuna izindlela zokunciphisa umthelela wethu emvelweni. Lesi sizathu sodwa singenye yezizathu ezenza sisebenzisa ukuphrinta kwe-UV ezinqubweni zethu.
