Izindlela Zokuphrinta
Ngokwetheknoloji, kunezindlela eziningana zokunyathelisa, njengokuphrinta okuqondile, ukunyathelisa kokukhipha kanye nokumelana nokuphrinta.
Ekuphrinteni okuqondile, ukunamathisela kokuphrinta kufanele kulungiswe kuqala.Okunamathiselwe, okufana nokunamathisela kwe-alginate noma okunamathiselwe kwesitashi, kudinga ukuxutshwa ngesilinganiso esidingekayo nodayi namanye amakhemikhali adingekayo njengama-ejenti wokumanzisa kanye nama-ejenti okulungisa.Lezi zibe sezinyatheliswa ngendwangu emhlophe yomhlabathi ngokuvumelana nemiklamo oyifunayo.Ngezindwangu zokwenziwa, ukunamathiswa kokuphrinta kungenziwa ngezingulube esikhundleni samadayi, bese ukunamathisela okuphrinta kuzohlanganisa i-pigments, ama-adhesives, i-emulsion paste namanye amakhemikhali adingekayo.
Ekushicileleni kokukhipha, indwangu yomhlabathi kufanele iqale idayiwe ngombala womhlabathi oyifunayo, bese umbala womhlabathi ukhishwa noma ufakwe i-bleached ezindaweni ezihlukene ngokuyiphrinta ngokunamathisela kokukhipha ukuze ushiye imiklamo ye-withe oyifunayo.I-dischargepaste ngokuvamile yenziwa nge-ejenti yokunciphisa njenge-sodium sulphoxylate-formaldehyde.
In ukumelana ukuphrinta.izinto ezimelene nokudaya kufanele ziqale zifakwe endwangu yomhlabathi, bese indwangu idaywe.Ngemuva kokuthi indwangu idayiwe, ukuphikiswa kuzosuswa, futhi imiklamo ibonakala ezindaweni lapho ukuphikiswa kwanyatheliswa khona.
Kukhona nezinye izinhlobo zokuphrinta, isibonelo, ukuphrinta kwe-sublistatic kanye nokuphrinta komhlambi.Ekhoneni, umklamo uqala ukuphrintwa ephepheni bese iphepha elinemiklamo licindezelwa ngokumelene nendwangu noma izingubo ezifana nezikibha.Lapho kusetshenziswa ukushisa, imiklamo idluliselwa endwangu noma engutsheni.Ekugcineni, izinto ze-shourt fibrous zinyatheliswa ngamaphethini ezindwangu ngosizo lwezinamathiselo.I-Electronstatic flocking ivame ukusetshenziswa.
Izisetshenziswa Zokuphrinta
Ukuphrinta kungenziwa ngokuphrinta nge-roller, ukuphrinta isikrini noma, kamuva nje, imishini yokuphrinta ye-inkjet.
1. Ukuphrinta Roller
Umshini wokunyathelisa we-roller ngokuvamile uhlanganisa isilinda esikhulu sokucindezela okumaphakathi (noma esibizwa ngokuthi isitsha sokucindezela) esimbozwe ngerabha noma izinsephe ezimbalwa zendwangu ehlanganisiwe yelineni yoboya enikeza isilinda indawo ebushelelezi futhi ecindezelwayo enwebekayo.Amarola ethusi amaningana aqoshwe ngemiklamo ezophrintwa abekwe eduze kwesilinda sokucindezela, i-roller eyodwa yombala ngamunye, ethintana nesilinda sokucindezela.Njengoba ezungeza, amarola okuphrinta aqoshiwe, ashayelwa kahle, aphinde ashayele i-roller yawo yefenisha, bese eyakamuva ithwala okunamathiselwe okunyathelisayo isuka ebhokisini layo lombala iye kurola wokunyathelisa oqoshiwe.Insimbi ebukhali ebizwa ngokuthi i-cleaner doctor blade isusa ukunamathisela okweqile kurola yokuphrinta, futhi enye i-blade ebizwa ngokuthi i-lint doctor blade ikhipha noma iyiphi i-lint noma ukungcola okubanjwe irola yokuphrinta.Indwangu ezophrintwa idliswa phakathi kwamarola okuphrinta kanye nesilinda sokucindezela, kanye nendwangu empunga esekelayo ukuvimbela ubuso besilinda ukuthi bungabi namabala uma ukunamathisela kombala kungena engutsheni.
Ukuphrinta kwe-roller kunganikeza ukukhiqiza okuphezulu kakhulu kodwa ukulungiswa kwama-roller okuphrinta aqoshiwe kuyabiza, okwenza, empeleni, afaneleke kuphela ukukhiqiza okude.Ngaphezu kwalokho, ububanzi berola yokuphrinta bukhawulela usayizi wephethini.
2. Ukuphrinta Isikrini
Ukuphrinta kwesikrini, ngakolunye uhlangothi, kufanelekile kuma-oda amancane, futhi kulungele ikakhulukazi ukuphrinta izindwangu ezinwetshiwe.Ekuphrinteni kwesikrini, izikrini zokuphrinta zemeshi ezilukiwe kufanele ziqale zilungiswe ngokwemiklamo ezophrintwa, eyodwa ngombala ngamunye.Esikrinini, izindawo lapho okunamathiselwe kombala okufanele kungene khona zimbozwe ngefilimu enganyibiliki eshiya izikhala zesikrini ezisele zivuliwe ukuze kuvunyelwe ukunamathisela okuphrintiwe ukuthi kungene kuzo.Ukuphrinta kwenziwa ngokuphoqa ukunamathisela okuphrinta okufanele ngephethini yemeshi kundwangu engaphansi.Isikrini silungiswa ngokumboza isikrini nge-photogelatin kuqala bese sibeka phezulu isithombe esingesihle sedizayini kuso bese sisibeka ekukhanyeni okulungisa kanye nembobo yefilimu engancibiliki esikrinini.I-coating igezwa kulezo zindawo lapho ukunamathela kungazange kwelapheke, kushiye ama-interstices esikrinini evulekile.Ukuphrinta kwesikrini kwendabuko ukuphrinta kwesikrini esiyisicaba, kodwa ukuphrinta kwesikrini esijikelezayo nakho kudume kakhulu ngokukhiqiza okukhulu.
3. Ukuphrinta kwe-Inkjet
Kungabonakala ukuthi phakathi kokunyathelisa nge-roller noma ukuphrinta isikrini ukulungiswa kudla isikhathi nemali nakuba izinhlelo ze-Computer Aided Design (CAD) ziye zasetshenziswa kabanzi ezimbonini zokunyathelisa eziningi ukuze zisize ekulungiseleleni ukuklama.Imiklamo ezophrintwa kufanele ihlaziywe ukuze kunqunywe ukuthi yimiphi imibala engase ihileleke, bese kulungiselelwa amaphethini angalungile ombala ngamunye futhi adluliselwe kumarola okuphrinta noma izikrini.Ngesikhathi sokuphrinta isikrini ekukhiqizweni okukhulu, okujikelezayo noma okuyisicaba, izikrini zidinga ukushintshwa futhi zihlanzwe njalo, okubuye kudle isikhathi nomsebenzi.
Ukuze kuhlangatshezwane nesidingo sanamuhla semakethe sokusabela okusheshayo kanye nosayizi abancane beqoqo ubuchwepheshe bokuphrinta be-inkjet buya ngokuya busetshenziswa.
Ukuphrinta kwe-inkjet ezindwangu kusebenzisa ubuchwepheshe obufana nobo obusetshenziswa ekuphrinteni iphepha.Ulwazi lwedijithali lomklamo odalwe kusetshenziswa uhlelo lwe-CAD lungathunyelwa kuphrinta ye-inkjet (noma evame ukubizwa ngokuthi iphrinta ye-inkjet yedijithali, futhi izindwangu eziphrintwe ngayo zingabizwa ngokuthi izindwangu zedijithali ) ngokuqondile futhi ziphrintwe ezindwangu.Uma kuqhathaniswa nobuchwepheshe bokuphrinta bendabuko, inqubo ilula futhi isikhathi esincane nekhono liyadingeka njengoba inqubo izenzakalela.Ngaphezu kwalokho, kuzoncipha ukungcoliswa kokungcola.
Ngokuvamile, kunezimiso ezimbili eziyisisekelo zokuphrinta inkjet yezindwangu.Enye i-Continuous Ink Jetting ( CIJ ) kanti enye ibizwa ngokuthi “Drop on Demand” (DOD).Esimeni sangaphambilini, ingcindezi ephezulu kakhulu (engaba ngu-300 kPa) eyakhiwe ngepompo yokuphakela uyinki iphoqa ukuthi uyinki uphume emlonyeni, ububanzi bawo obuvame ukuba ngama-micrometres ayi-10 kuye kwayi-100.Ngaphansi kokudlidliza kwefrikhwensi ephezulu okubangelwa isidlidlizi se-peizoelectric, uyinki ube esehlukaniswa ube ukugeleza kwamaconsi futhi ukhishwe emlonyeni ngesivinini esikhulu kakhulu.Ngokwale miklamo, ikhompuyutha izothumela amasignali ku-electrode yokushaja eshaja ngogesi amaconsi kayinki akhethiwe.Uma edlula kuma-electrodes achezukile, amaconsi angashajwa azoqonda ngqo kudoti oqoqayo kuyilapho amaconsi kayinki ashajiwe azophambukiselwa endwangu ukuze akhe ingxenye yephethini ephrintiwe.
Kuhlelo "lokwehla kokufunwayo", amaconsi kayinki anikezwa njengoba edingeka.Lokhu kungenziwa ngokusebenzisa indlela yokudlulisa i-electromechnical.Ngokuvumelana namaphethini azophrintwa, ikhompuyutha ithumela amasignali ashaya ngamandla ensizeni ye-piezoelectric yona yona ikhubazeke futhi ikhiqize ingcindezi egumbini likayinki ngokusebenzisa into evumelana nezimo.Ukucindezela kubangela ukuthi amaconsi kayinki akhishwe emlonyeni.Enye indlela evame ukusetshenziswa kunqubo ye-DOD ngokusebenzisa indlela yokushisa kagesi.Ngokusabela kumasiginali wekhompyutha iheater ikhiqiza amabhamuza egumbini likayinki, futhi amandla anwebekayo amabhamuza abangela ukuba amaconsi kayinki akhishwe.
Indlela ye-DOD ishibhile kodwa ijubane lokuphrinta nalo liphansi kunalelo lesu le-CIJ.Njengoba amaconsi kayinki ekhishwa ngokuqhubekayo, izinkinga zokuvala umlomo wombhobho ngeke zenzeke ngaphansi kwesu le-CIJ.
Amaphrinta e-inkjet ngokuvamile asebenzisa inhlanganisela yemibala emine, okungukuthi, i-cyan, i-magenta, ephuzi kanye emnyama ( CMYK ), ukuphrinta imiklamo ngemibala ehlukahlukene, ngakho-ke amakhanda okuphrinta amane kufanele ahlanganiswe, elilodwa ngombala ngamunye.Kodwa-ke amanye amaphrinta ahlome ngamakhanda okuphrinta angu-2*8 ukuze ngokwethiyori kufike imibala eyi-inki eyi-16 ingaphrintwa.Ukulungiswa kokuphrinta kwamaphrinta we-inkjet kungafinyelela ku-720*720 dpi.Izindwangu ezingaphrintwa ngamaphrinta e-inkjet zisukela emiculweni yemvelo, enjengokotini, usilika noboya, kuya emiculweni yokwenziwa, efana ne-polyester ne-polyamide, ngakho-ke kunezinhlobo eziningi zikayinki ezidingekayo ukuze kuhlangatshezwane nesidingo.Lokhu kuhlanganisa oyinki abasebenzayo, oyinki be-asidi, oyinki abahlakazayo kanye noyinki abanemibala.
Ngaphandle kwezindwangu zokunyathelisa, amaphrinta e-inkjet angasetshenziswa futhi ukuphrinta isikibha, ama-sweatshirts, ama-polo shirts, ukugqoka kwezingane, ama-apron namathawula.
