UV luam ntawv sawv cev yog ib feem tseem ceeb ntawm kev lag luam luam ntawv. Advanced post-press processing-xws li cov ntawv kub kub stamping, lamination, embossing / debossing, thiab ntau hom txheej txheej tshwj xeeb- tau dhau los ua ib qho chaw, nrog "tshwj xeeb-tshuaj" coatings tawm los ua ib qho tseem ceeb. Qhov nce ntawm cov txheej txheem txheej txheej txheej no yog qhov loj heev los ntawm kev nce qib ntawm kev siv technology thiab kev hloov pauv ntawm cov ntawv luam tawm. Hauv kev tsim cov folding cartons rau cov tshuaj pleev ib ce thiab cov khoom lag luam luam yeeb, daim ntawv-fed offset presses tseem yog cov thev naus laus zis tseem ceeb. Rau cov khoom uas tsis tuaj yeem ua tau zoo los ntawm kev luam ntawv offset, kev tshuaj ntsuam luam ntawv lossis cov ntawv sau gravure luam ntawv feem ntau yog ua haujlwm. Niaj hnub nimno daim ntawv-fed offset presses yog tam sim no niaj hnub nruab nrog ntau yam hauv-kab txheej txheej, ua kom yooj yim rau kev siv seamless ntawm cov txheej txheem tshwj xeeb. Qhov no yog tshwj xeeb tshaj yog muaj feem xyuam rau cov tshuaj pleev ib ce ntim, uas nquag siv tshwj xeeb substrates-xws li hlau, laminated, los yog metallized paperboard, raws li zoo raws li pre-coated boards-tag nrho cov uas yog pom loj hlob saws thiab ruaj khov, ruaj khov kev lag luam. Tsis tas li ntawd, cov ntaub ntawv pob tshab tshiab tau siv ntau dua rau kev ntim khoom yas. Vim tias cov substrates no tsis tuaj yeem ua tiav siv cov txheej txheem ib txwm siv, UV thev naus laus zis tau dhau los ua qhov tseem ceeb kom ua tiav qhov kev xav pom; Yog li ntawd, ob qho tib si UV-kho tau cov txheej txheem thiab UV-kho tau inks tau pom kev siv dav. Muab qhov trajectory no, UV luam ntawv tau teeb tsa los ua tus qauv kev lag luam, kom ntseeg tau tias cov khoom tsim tau zoo, tsis yog kev cia siab rau qhov tsis muaj peev xwm ntawm cov txheej txheem ib txwm muaj. Cov txheej txheem kho kom ruaj khov ntawm kev xa khoom kawg-nrog rau cov chav kho nruab nrab-tsis suav tias yog "khoom kim heev" ntxiv-ons, tab sis cov khoom tseem ceeb. Cov peev txheej no muab kev lag luam luam tawm nrog cov dav dav ntawm daim ntawv thov kev muaj peev xwm, ua tau raws li qhov nyuaj thiab tshwj xeeb ntawm kev lag luam ntim tshuaj pleev ib ce.
