Ukuphrinta kwe-offset kuyinqubo esetshenziswa kakhulu yokunyathelisa yezentengiselwano ehlanganisa ukudlulisa uyinki usuka epuleti lokunyathelisa uye kwengubo yenjoloba bese ungena endaweni engaphansi yokuphrinta, ngokuvamile eyiphepha.Kunezinhlobo ezimbili eziyinhloko zemishini yokunyathelisa ye-offset: Imishini yokunyathelisa ye-UV offset kanye nemishini evamile yokunyathelisa ye-offset.Nakuba zombili izinhlobo zemishini zisebenzisa izimiso ezifanayo ukuze zidlulisele uyinki ephepheni, kunomehluko obalulekile phakathi kwazo.

Umshini Wokuphrinta we-UV Offset: Umshini wokuphrinta we-UV offset usebenzisa ukukhanya kwe-ultraviolet (UV) ukwelapha uyinki ngemva kokuba udluliselwe ku-substrate.Le nqubo yokwelapha idala uyinki osheshe wome ophumela emibaleni egqamile nemifanekiso ebukhali.Uyinki we-UV welapheka ngokuchayeka ekukhanyeni kwe-UV, okubangela ukuthi uyinki uqine futhi uhlangane ne-substrate.Le nqubo ishesha kakhulu kunezindlela zokomisa zendabuko, okuvumela isivinini sokuphrinta esisheshayo kanye nezikhathi zokumisa ezimfushane.

Enye yezinzuzo ezibalulekile zokuphrinta kwe-UV offset ukuthi ivumela ukusetshenziswa kwezinhlobonhlobo zama-substrates, okuhlanganisa ipulasitiki, insimbi, nephepha.Lokhu kuyenza ibe indlela ekahle yokuphrinta yemikhiqizo efana nokupakishwa, amalebula, nezinto zokukhangisa.Ukusetshenziswa koyinki we-UV kuphinda kubangele ukuphrinta kwekhwalithi ephezulu kakhulu, okunemifanekiso ebukhali, ecacile nemibala egqamile.

Umshini Ovamile Wokuphrinta we-Offset: Umshini wokunyathelisa ovamile we-offset, owaziwa nangokuthi umshini ovamile wokunyathelisa we-offset, usebenzisa uyinki osekelwe kuwoyela ogxiliswa ephepheni.Le inki isetshenziswa epuleti lokuphrinta futhi idluliselwe engutsheni yenjoloba ngaphambi kokudluliselwa ku-substrate.Uyinki uthatha isikhathi eside ukomisa kunoyinki we-UV, okusho ukuthi isivinini sokuphrinta sihamba kancane futhi izikhathi zokumisa zinde.

Enye yezinzuzo eziyinhloko zokuphrinta kwe-offset okujwayelekile ukuthi kuyindlela yokuphrinta eguquguqukayo engasetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, kusukela kumakhadi ebhizinisi kuya kumaphosta anefomethi enkulu.Futhi kuyindlela yokuphrinta engabizi kakhulu yokuphrinta okukhulu, njengoba izindleko zephrinta ngayinye ziyancipha njengoba umthamo wokuphrinta ukhuphuka.

Umehluko Phakathi Kwemishini Yokuphrinta Ye-UV kanye Neyejwayelekile ye-Offset:

1. Isikhathi Sokumisa: Umehluko omkhulu phakathi kokuphrinta kwe-UV offset nokuphrinta okujwayelekile kwe-offset yisikhathi sokumisa.Uyinki we-UV woma cishe ngaso leso sikhathi lapho uvezwe ekukhanyeni kwe-UV, kuyilapho u-inki wendabuko uthatha isikhathi eside ukuze wome.
2. I-Substrate: Ukuphrinta kwe-UV offset kungasetshenziswa kuhlu olubanzi lwama-substrates kunokuphrinta okujwayelekile kwe-offset, okuhlanganisa ipulasitiki, insimbi, nephepha.
3. Ikhwalithi: Imiphumela yokuphrinta ye-UV offset ekuphrintiwe kwekhwalithi ephezulu kakhulu enezithombe ezicijile, ezicacile nemibala egqamile, kuyilapho ukuphrinta kwe-offset okuvamile kungase kuphumele ekuphrinteni okuncane.
4. Izindleko: Ukuphrinta kwe-UV offset ngokuvamile kubiza kakhulu kunokuphrinta okujwayelekile kwe-offset, ngenxa yezindleko zikayinki we-UV kanye nezisetshenziswa ezikhethekile ezidingekayo.

Kafushane, imishini yokunyathelisa ye-UV offset kanye nemishini yokunyathelisa ye-offset evamile yomibili isetshenziswa kabanzi embonini yokunyathelisa, kodwa ihluke ngokwesikhathi sokumisa, i-substrate, ikhwalithi, kanye nezindleko.Ngenkathi ukuphrinta kwe-UV offset kuyinketho ebiza kakhulu, kunikeza isivinini sokuphrinta esisheshayo, ikhwalithi engcono, nekhono lokuphrinta kuhlu olubanzi lwama-substrates.Ngakolunye uhlangothi, ukuphrinta okujwayelekile kwe-offset kuyindlela eguquguqukayo futhi engabizi kakhulu yokuphrinta okukhulu kwezinto zendabuko ezifana nephepha.

Ukupakisha kwe-SIUMAI kusebenzisa imishini yokuphrinta ye-UV offset ukuphrinta amabhokisi okupakisha kuwo wonke ulayini, ukunciphisa ukungcoliswa kwemvelo nokuqinisekisa ikhwalithi yamabhokisi okupakisha isesimweni sekhwalithi ephezulu.
