Ukukhomba (Uhlaka lwe- "Freeze") Ngokushesha ngemuva kokuthi ikhanda ...

Ukuhlanganisa uhlelo lokuphulukisa lwe-UV LED lokuphrinta ngokujwayelekile kuhilela ukufaka ama-arrays e-LED aphezulu ekugcineni kokucindezela (EOP) noma phakathi kwamayunithi wokuphrinta (interdeck). Lobu buchwepheshe buthatha indawo yama-dryers emoyeni oshisayo noma we-mercury UV, okuvumela ukuphulukiswa okusheshayo kwama-inks kuwo womabili amaphepha ajwayelekile kanye nama-substrates okwenziwa azwela ukushisa. Ezitolo eziningi zokuphrinta, ukuhlanganiswa kuza ngezindlela ezimbili eziyinhloko: ukubuyisela kabusha umshini okhona we-sheetfed ngamakhanda wesibani se-LED noma ukucacisa umshini omusha ngohlelo lwe-OEM olufakwe ngaphambilini. Inzuzo eyinhloko ilele "ekwelapheni okupholile"; ngoba i-UV ye-LED ikhipha ama-wavelengths athile (imvamisa i-385nm noma i-395nm) ngaphandle kokushisa okukhulu kwe-infrared kwezibani ezivamile, ungaqeda i-spray powder, unciphise ukusetshenziswa kwamandla kuze kufike ku-70%, futhi uhambise izinqubo zokuqeda ngokushesha ku-bindery. Retrofitting vs. New Press Integration Lapho ucabanga ukuthuthukiswa kwe-UV LED, isinqumo sokuqala ngokuvamile ukuthi uthuthukise imishini yakho yamanje noma utshale imali kumishini emisha yemali. Zombili lezi zindlela zisebenzisa ubuchwepheshe obufanayo be-LED, kepha inqubo yokuhlanganiswa iyahlukahluka. Retrofitting Existing Presses Ukubuyisela emuva kuyisinqumo esithandwayo sokwandisa impilo yensimbi enokwethenjelwa. Uhlelo lokuphulukisa lwe-UV LED lokuphrinta lwe-offset luhlangene ngokwanele ukuthi lungangena ezikhaleni zokulethwa noma ze-interdeck zemishini eminingi ejwayelekile (njengeHeidelberg, iKomori, noma iManroland) ngaphandle kokulungiswa okukhulu kwemishini. Ukuhlanganiswa kwe-OEM Ukuthenga umshini omusha nge-UV ye-LED ehlanganisiwe efektri kuqinisekisa ukuxhumana okungenamthungo phakathi kwekhonsoli yokucindezela nohlelo lokuphulukisa. Imigqa yokupholisa, ukunikezwa kwamandla kagesi, kanye nokuphepha kwakhiwe ekwakhiweni ...
