Ingabe ukuphulukiswa kwe-UV LED kungasetshenziselwa ukuphrinta kwe-offset?

Ngabe ukuphulukiswa kwe-UV LED kungasetshenziselwa ukuphrinta kwe-offset emakethe yanamuhla yokuncintisana? Impendulo emfushane ingu-yebo ocacile. Lobu buchwepheshe akuyona nje enye indlela; Ngokushesha iba indinganiso yomkhakha yokusebenza kahle. Kwaphela amashumi eminyaka, amaphrinta e-offset athembele ezibani ze-mercury ezishisayo, ezilambile amandla noma izifutho ze-powder ukomisa inki. Lezo zinsuku ziphela ngokushesha. Ukuphulukiswa kwe-UV LED kunikeza indlela epholile, esheshayo, futhi eyonga amandla yokukhiya inki ephepheni. Iguqula ukuthi izitolo zokuphrinta zisebenza kanjani, zinikeza izikhathi zokuguqula ezisheshayo nekhwalithi ephakeme kuma-substrates anzima.

Kulo mhlahlandlela, singene ngokujulile emishini, ezomnotho, kanye nokusetshenziswa okusebenzayo kobuchwepheshe be-UV LED emhlabeni we-offset.

Ingabe ukuphulukiswa kwe-UV LED kungasetshenziselwa ukuphrinta kwe-offset ngempumelelo?

Yebo, ukuphulukiswa kwe-UV LED kuphumelela kakhulu ukuphrinta kwe-offset futhi kufaka esikhundleni sempumelelo izindlela zokumiswa zendabuko. Isebenza ngokusebenzisa ama-Light Emitting Diode (LEDs) ukukhipha ibhande elithile elincane lokukhanya kwe-UV. Lokhu kukhanya ngokushesha kubangela ukusabela kwe-photochemical kuma-inks akhiwe ngokukhethekile, ukuwaguqula kusuka kuketshezi kuya kokuqinile ngama-milliseconds. Le nqubo idala ishidi elomile ngokushesha, okuvumela ukuqedwa okusheshayo ngaphandle kwesidingo se-anti-set-off powder noma izikhathi zokulinda.

The Shift From Heat to Cool Curing

Ngihambe emakamelweni okucindezela angenakubalwa lapho ukushisa okuvela ku-UV ejwayelekile noma ama-heatset dryers kwenza imvelo ingabekezeleleki. I-UV LED ishintsha lokho kuguquka ngokuphelele. Ngoba ama-LED akhipha amandla e-UV ngaphandle kokushisa kwe-infrared (IR) okuhambisana nezibani ze-mercury, le nqubo yaziwa ngokuthi "ukuphulukisa okupholile."

Lokhu kubaluleke kakhulu kumaphrinta we-offset. Ukushisa kwendabuko kunganciphisa amanzi emzimbeni ephepheni, kubangele izinkinga zokubhalisa noma "ukukhula kwewebhu" kuzinhlelo zokusebenza ze-roll-to-roll. Ngokususa ukushisa, uzinzisa i-substrate. Noma ngabe usebenzisa i-Heidelberg noma i-web offset Manroland, isimiso sihlala sifana: ukusetshenziswa kwamandla okuqondile kuholela ekwelapheni okusheshayo.

Idatha yokwamukelwa kwezimboni iphakamisa ukuthi iphesenti elikhulayo lokufakwa okusha kokucindezela kwe-offset manje liza lihlome noma lilungiselelwe ukwelashwa kwe-LED.
