Ukuthi yini indlela yokuphrinta amaphephandaba ayo aphakeme kwezinhlobo zokugcina ngokusebenzisa iphrinta yamaphu yezinhlobo?

Umbuzo Oyingcono: Kungani Izinhlobo Ziyabulala Imithombo YokuPhrinta Okwesibonelo

Ukuphrinta amaphephandaba ayo aphakeme kwezinhlobo zokugcina kuyisahluko esingqayile kokuPhrinta kwezinye izinyathelo. Izinhlobo zokuphrinta zomphu ziyakhetha isibonelo sokubaluleka kwesibonelo sokufana nokuthi kunezinye izinyathelo ezingaqondi kakhulu phakathi kwezinye izinyathelo nezinye izinyathelo. Ukubuka kwenyathelo kuyakha ukuguquka kokuphrinta, ukusukela kuyakha ukuguquka kokuhlanganisa, futhi izinyathelo ezinamandla ezingasikwazi ukuthi zilindelwe ngokuvamile kwezinhlobo zokugcina—funda iziphalaphala, izihlalo, nezinhlobo zokugcina ezinamandla—zisobala ukuthi zingasikwazi ukuthi zilindelwe ngokuvamile .

Ikhaya lokupakisha emhlabeni emphakathini wabona le nto ngokupheleleyo ngokuzama ukuguqula amalabeli asebenziswe kabefore kuma-printing yamadolo kusuka kwezinto zokusebenza kwezinsuku. I-printer yabo yesifunda se-UV yasemthwakweni yasenza iziphumo eziningi kubala lesikhathi kodwa yasenza lezinye iziqondiso zibe yizinhloko zezindaba zokuphinda kusuka kwezintlobo zokuprinta kumadolo. Amabharikhozi akasakhi. Izithombe zezinhlamvu zazibekwa kwezinye izihloko. Le ndawo yasimula izinsuku eziyishumi nesibili zokusebenza nokuthenga okukhulu kwezinkambo eziyisixhenxe ngaphambi kokuthi bakhuluma ukuthi i-machine ayikho inkambo—kodwa indlela yayo yinkambo.

Ukuqondana kwamanje kwenza izimo eziyisithathu zokufa ezingenakho kumaprinting esifunda. :

• Ukuhlupha kwesihloko kuyakha ngokuthi ukuphambana kwamanzi kwezihloko zomadolo kuyenza ukuthi amadropi we-ink asihluphe kahle, kuhlela izinhlamvu futhi kuhlela ukugcina kwezihloko zama-bharikhozi.

• Ukungafanani kwokuprinta kwezinye izinye kuyakha lapho iziqondiso zesiprinti esihlukaniswe—njengama-bharikhozi okuphinda kusuka kwezinye izinye—aziya kubuyela kusuka kwezinye izinye ngokuphinda kusuka kwezinye ngokuphinda kusuka kwezinye.

• Ukuphambana kwe-ink kubhekisa izinkqubo zokushisha ezisebenzisa amakhemikhali e-ink ezinamandla okushisha kwezinto ezinamandla okushisha okuphezulu, ngakho-ke izinkqubo zokushisha zokuvula kwe-UV zidinga ukuthi isithunywa sibe phakade kusuka kwezinye izinyathelo ezinamandla okushisha, okungasebenzi kulezi zinyathelo zokushisha zokuvula kwe-UV.

Ukuziphatha lezi zinkinga kudinga izinkqubo ezisalwa ngokwesifundo, akadinga izindlela zokuphinda zizame ukwenza izinto ngendlela eyengeziwe.

Ukukhala Inkqubo Ngamapikholita

Isibopho sokushisha esihle sokutshisa izinkqubo zokushisha kusuka kwezinkqubo zokushisha zokuvula kwe-piezoelectric. Lezi zinkqubo zishisha amakhemikhali okushisha okuthi amapikholita—bheka kuleli qembu lokuqala kwezilitha nezilitha eziningi ezinamandla okushisha—futhi ziyabeka ngokuthi zingaphansi kwamakhonki. level yokuqondisa kuyisibopho sokuthi izinkqubo zokushisha zingashaywa ngezinkqubo zokushisha zokuvula kwe-barcode nokuthi izinkqubo zokushisha zingashaywa ngezinkqubo zokushisha zokuvula kwe-shipment.

Isilimi esikhundleni siphakathi siyisikrithali esisemthethweni wesikrithali. Uma kubhekwa i-voltage, isikrithali sibadla, sisebenzisa iphulsi yomthelela okuvumela inkhawulo ekuphambeni kwesibhakabhaka. Ngokuthintela ifomu yomthelela nokukhanya kwezinyathelo, abasebenzi bakhuluma ukuthintela ubude nobunzima bomkhala wokubhala nokukhanya kwezinyathelo ukuqinisekisa ukuthi kuyafanele kumakhiya okwesibhakabhaka nokubonakala kwesibhakabhaka. Lokhu kubalulekile ngoba amasibhakabhaka ayisikhulu kakhulu kwezinhlobo zezinto—aluminum, polyethylene, polypropylene, iglashe, noma izinhlobo eziningi zezinhlobo zezinto—ngokwesibonakaliso sezinto zazo nezinhlobo zokufunda. .

Kwesixhobo sokubhala kwamapharama, lapho imithetho yase-FDA ibhekisa ukuthi izinkumbolo ezingavuswa ngomkhono ziyidingekile ngokwesiqondiso se-21 CFR Part 11, lokhu ukuthintela umkhala akwadingeki. isibhakabhaka esisilinganayo singabangela ukuthi kubuyiselwe isibhakabhaka esingasendaweni yokubhala, okungaba yinkulu kunalesixhobo sokubhala. Ukuthola ukuthi kubhala amagama angu-2-point nokubhala izinkumbolo zokubhala ezinobuhlungu obukhulu kwezinye izinyathelo zokubhala kuyakwazi ukuthi kubhale amasibhakabhaka okwesibhakabhaka ngokuphelele.

Ukubuyisa kwe-UV: Ukubuyisa okuxhumana ngokushesha

Ukuthi inkhulu yekhala kakhulu akukho mlando uma inkhulu ayikwazi ukuhlala apho akhulwe khona. Kuma-tjube, ukubambisana kwe-inkhulu kufaka isibonelo esikhulu sokuchaza: amasurfesi angavuli, ukudlula okuphakathi, nokuzilanda okwenza umzimba wokugcina, ukugcina, nokuthumela ama-tjube.

Ama-inkhulu athi aya kuvula ngokusha kwe-UV asindisa lezinto ngokusha kokupolimeriza. Ngomuhla owesibonelo sokuqhubeka kwesibonelo se-UV kusuka kuma-inkhulu awatholakayo, ama-photoinitiators abuyisa indlela yokuchaza okuyenza umsindo we-inkhulu wokusha ukuba yiba yisifilm yesolid polymer—ngemizuzwana emibili. lokhu kusha okusha kuhlinzeka ukunqamuka nokunqamuka okukhona kuma-inkhulu ethi ayisebenzi ngokusha kwe-solvent kuma-surfaces okungafanele, khusela kuma-edges apho ukunqamuka kuyakhala kakhulu.

Ukuqinisa ukukhanya kwenkumbulo kungaqiniswa ngokusebenzisa ukuziphatha kwe-ASTM D3359 okuphathelene nokugcina inkumbulo kumkhakha wakho, okuyindlela eyisisekelo ekubonisa ukuthi inkumbulo iyakukhanya kanjani kumkhakha wakho. Amakhodi okuqukethwe ngokuqukethwe kwe-UV kuma-tubes okuphawulwe ngokuphelele kusenza isimo sokukhanya kwe-4B uye ku-5B ngalesi sikhathi, okusho ukuthi akukho zinkumbulo ezingu-5% okukhanywa ngokuphanda kwesithili. Ngokuchaza, lokhu yisimo esifanayo sokukhanya sokufanele kuma-inkumbulo okwesayensi ema-tube okwesilwandle.

Ukuphepha kwezinkumbulo kuvumela ukusebenzisa ngokwedlulela ngokomlando. Ima-tube ingahamba ngokwedlulela kuma-line yokufaka noma kuma-station yokupaka ngaphandle kokulindela ukuthi inkumbulo iphephe—lokhu kukhona kwezindlela zokusebenza okuyakubiza ngokwedlulela ukuthi izinto ezingazihlukaniswa ziyakwazi ukuba zingabizwa ngokwedlulela futhi ukuthi izikhathi zokubiza ziyakwazi ukuba zingabizwa ngokwedlulela.

Ukubambisana: Ukuphatha Isikhathi Sokubambisana

Ukuphrinta kuma-tube akuyiyo kuphela ukuthi ubheka indawo yokubeka inkumbulo—kuyiyo ukubeka inkumbulo kwindawo ephakade kanye nesikhathi esiphakade njengoba umtshelo uphambana ngaphezulu kwe-printhead. Lokhu kukhona lapho i-rotary encoders ziyakwazi ukuthi zibambisane.

I-rotary encoder isebenzisa indawo yokubhala kwe-tube ngokushesha, ishika lethu kumkontrolleli wendawo yokubhala . Umkontrolleli usebenzisa leminyathelo ukuthi amakhanda akhuphuke ngexesha lokukhuphuka ukuze izithunzi zibhekele kuwo okufanele, ngaphandle kokuba kukhona izilinganiso zezigaba zokugula noma izinkinga zokubhala kwezinyathelo zokubhala. Uma akukho le ndlela yokubhala ngokuvamile, even small amounts of slippage—a fraction of a degree—can throw off registration by millimeters, which is catastrophic for high-resolution graphics.

Ukubhekana nokuhlanganisa kuyadlula ngokwamanzi kwe-tube ezingenayo, apho ubude bewo buyagqibela ngokwesikhathi sokubhala. Umkontrolleli wendawo yokubhala kufanele ukuthi abeke izikhathi zokukhuphuka ngokushesha ukuze kubhekwe izithunzi zokubhala ngokufanayo kuzo zonke izindawo zokubhala ezihlukene. Izinhlelo eziphezulu ziyasebenzisa lezi zinhlelo ngokusebenzisa izinkambo ezilungileyo zokubhala kwe-tube futhi zikwenza iziphakanyiselo ngokushesha .

Amanombolo ayabiza indaba. Amaphrinta amahle asebenzisa izithuthi zokuzimela ukuthi abe nezinkinga ezingaphezulu kwezinye ezihlukaniswe, kodwa abekhona nesiphumo esihle kakhulu kwenhlaka yobugcisa—izithuthi ezibuka, akuzi-ziqondiso zokuzimela.

Ukukhetha nokuhlela i-printhead

Akukho printheads okunye kwezinye, futhi ukwahluka kwenza umlinganiselo wokubonakala kwezindlela zokuphrinta amathuba. Amaphrintihed esayensi yasezindustria njengeRicoh Gen6 series abona izinto ezithile ezinconywa ngokuphelele kwezindlela zokuphrinta ezingcwele: izinyathelo zokuphrinta ezahlukene, izikhathi zokuphrinta eziningi, nokuzimela inkqubo yokusebenzisa amasimu okuhambisa inkqubo yokuphrinta okwamanje noma ngamakhemikhali okuphrinta kwe-UV .

Ukugcinwa kwakho kuyaphakamisa futhi. Izinhlobo zezinkampani eziningi zokugcinwa nezinkampani ezithile zokugcinwa kwe-CMYK, i-white, nokuvamisa kusiza ukuphrinta amafoto e-color yonke nge-white opaque underlays—kuyisisekelo sokuphrinta emathubeni amadala noma amathuba athulile ilayiya yomkhulu yomthubi yasinda isibonakaliso esidingekayo ukusiza amahleli ukubonakala, futhi i-vamish inika ubuciko nobukhaya.

Izinqubo zokusebenzisa i-servo zihlaziya futhi ubuncinane ngokukhipha izinkinga zokusebenzisa izinqubo zokuphrinta zokusebenzisa i-belt . Amadilika amathuba okukhanya okwesikhathi esihlukene, okutholakala kwezinhlobo eziningi zokuphelela, aqhubeka ngokwenza ukudlula okungabi nengxenye yokuqondisa nokungabi nokuqondisa okunye, okuhlinzeka ukuthi isikhundla sesikhombisa kunye nesiphakathi sasembonini siyabuyela ngokubaluleka kwesikhundla sokugcina .

Izinkinga Zokusebenza Okulandelwe Ngokwempilo

Ukufumana iziphumo eziningi kwe-printer yamathuba ayisithathu kuzodinga ukuthenga ubukhulu obulingi kuphela. Izingxenye eziningi zokusebenza ziyakhuluma ukuthi iphrinti iyabuyela ngokubaluleka kwesikhundla sokugcina:

1. Ukuvuselela Kwenhloko kubalulekile kakhulu. Ukupretreat ngokwesikhathi esihlukene noma ngokwesikhathi esihlukene kususa umthelela wokuphatha, kubiza umthelela wokuphatha, kubiza ukuthi inkhawu iyahluka kanye nokuhlanya. Izinga eziningi ziyagcina lokhu ngokwesikhathi esihlukene, kwenza umsebenzi owodwa ukususa umthelela wokuphatha ku-printing ku-curing .

2. Ukukhetha inkhawu kufanele ikhethwe ngokwesibonelo sokuthi amathuba ayisithathu kanye nokuthi iphrinti iyabuyela ngokwesibonelo sokuthi amathuba ayisithathu. Izinkhawu eziningi zokusebenza ngokwesikhathi esihlukene ziyasebenza ngokwesibonelo sokuthi amathuba ayisithathu—lokho okusebenza kwi-aluminum kungasebenzi kahle kwi-polypropylene.

3. Umsebenzi Wesi-RIP iyagqamisa iziqondi zezindawo zokuphrinta kubizo lwezinyathelo zokuphrinta. Ubukhulu bekho buphinde buphinde konke kusukela kubukhulu bekubala kuze kufika ekuphakanyiseni kwemithombo.

4. Ukuphepha okuphephile —kungakhathalisi ukuchitha iprint head ne-encoder calibration—kukhulisa ukuthi ubukhulu buphinde buphinde ngokugcwele ngenxa yokuqhubeka kwesikhathi.

Umsebenzi wokuphrinta wezinto zokusebenza kwezintloko eNew Jersey wabasebenzisa lezi zinhlelo emva kokuzwa ukuthi ubukhulu bekuphrinta kuyaphinda kuyaphinda phakathi kwezinyathelo zezintloko ezahlukeneyo. Ngokwenza isikhathi sokuphrinta sifanayo, ukuguqula inkolimba yokuqinisa eyenzelwe izinto zezintloko zabo zokuphrinta, nokwenza isikhathi sokuphrinta esingasemva kwesikhathi esinye, bakhula ubukhulu bekuphrinta okungafanelekile kusukela kumthwalo wama-4% kuze kufika emthwaleni wama-1% ngeminyaka emibili. Ukuthi ubukhulu bukhulule kungabikho inkokhelo entsha—kodwa kuphela ubukhulu obuhle bokusebenza kwezinhlelo zezinyathelo zabo.

Lapho ukuphrinta kwezintloko kuyasebenza

Amathuba okuphrinta kwe-tube akhona kuzo zizindikayo ezithile kodwa akayi impendulo eyodwa kuzo zonke izindlela zokusebenza. Akhona kakhulu kuzo izindlela eziphakeme kanye nezimnyama apho ukuthenga kwe-screen printing noma kwe-flexography akuyiyo yomthwalo wokubekisa. ziyisifundamenthe sokuphrinta amaphuzu okuhlanganisa—amakodi okugqibela, amaphoto okukhetha ngokwezinye, noma amaphakathi okuqondwa kwenhlangano eyodwa eyahluka ngokwezinye ukuphrinta.

Izinkinga ziyisisekelo esikhulu sokubonisa. Amathuba okuphrinta kwe-tube ayisebenzi ngemvula emncane kunamathuba okuflexographic okuthengiselwe ngokuphelele ukuphrinta kwezinhlangano ezingaphezulu. Ikhanda lokuphrinta kuyaphansi kwezindlela zezinhlangano ezingaphezulu kakhulu. Futhi le teknoloji iyasebenza ngempilo kakhulu kuzo zintabagwe ezinamandla okunyuka—ukuthatha kwezintabagwe eziningi noma amasayizi okungafanele kakhulu akhuthaza izinkinga ezingahlinzeka ngokuphelele nangamathuba okunye.

Kusenhlangu esinamandla okuphrinta, ukuchangezwa nokubaluleka kokulungile kwezinhlangano, amathuba okuphrinta kwe-tube ayisifundamenthe sokuphrinta okungafanele kwezinhlangano ezingaphezulu kwezinhlangano ezihlukene.

Izinkampani ezithi NOVA zavela iziphumo zesayikili zokuphrinta okuzimele ekubhekiseni kwezinkinga zokuphrinta kwezikhala—kukhona ukukhetha kwezikhombi zokuphrinta, ukuthi inkhulu yekhankhali, ukulawula ukusuka kwezinyathelo, nokuvimba kokuvimba—kodwa kuyisibonelo sokuprodukha okunikeza ubukhulu obuhle bokuphakathi kweminyathelo yokuprodukha .
