Iyini i-flexography?

Ubuciko bezithombe zethulwe kakhulu emhlabeni we-graphic design. Kakhulu ukuthi ukuphrinta sekuyingxenye ye-50% yenani eliphelele ezingxenyeni zephrojekthi yokuklama.

Kulokhu okuthunyelwe, sichaza ukuthi i-flexography iyini, uhlobo lokunyathelisa olusetshenziswa kabanzi kuwo wonke ama-packaging design futhi hhayi lokho kuphela, kodwa futhi luyingxenye yomkhakha wokukhangisa nokuthengisa. Indlela yokuxhumana nenkampani yethu futhi siyiphrojuse ngendlela engathi sína kakhulu futhi enobuchwepheshe.

Lapha sichaza leli gama ukuguquguquka futhi sichaza ukuthi inaziphi izici.

i-flexography

Igama elithi flexographic noma eyaziwa nangokuthi i-flexographic printing, ingenye yeziningi izindlela kanye nezinhlobo zokunyathelisa ezikhona emhlabeni wokunyathelisa. Okugqamayo ngale ndlela eyaziwayo ukuthi basebenzisa amapuleti ngendlela yokusiza lapho enyatheliswa kuma-substrates ahlukene esiwazi njengamafilimu. i-polyester, inayiloni, insimbi, iphepha, amakhadibhodi noma izindwangu, okungezona izindwangu.

Le ndlela yokunyathelisa yenzeka ekuqaleni kwawo-20 e-United States kodwa ingeyaseFrance. Kusukela ngomzuzu wokuqala ukuphrinta kabusha kwe-aniline lapho kwakugqame kakhulu khona oyinki noma izimibalabala ezincane ezazisetshenziswa ngaleso sikhathi. Emashumini eminyaka neminyaka kamuva, yaqanjwa kabusha njengoba siyazi namuhla, i-flexography.

umlando omncane owengeziwe

Ngo-1890 uBibby Baron waklama umshini wokuqala eyayihlanganisa isilinda esisizwayo sokunyathelisa semibhoshongo enemibala ezungezwe isigubhu ukuze kunyatheliswe izikhwama zephepha. Iqiniso liwukuthi ukusungulwa njengalokhu akuzange kuphumelele, kodwa kubhekwa ngempela umsuka womshini wokuqala wokunyathelisa we-flexography njengoba siwuqonda namuhla.

Ngemva kweminyaka embalwa, ngo-1905, umshini wokuqala we-flexographic wawunelungelo lobunikazi okuhloselwe ukuphrinta izikhwama zephepha, ezazisebenzisa amafutha e-aniline ahlanjululwe otshwaleni njengama-colorants. Eminyakeni engu-XNUMX kamuva, le nqubo kakade yayaziwa eJalimane ngokuthi ukunyathelisa kwenjoloba.

I-Flexography isetshenziswa njengenqubo yokuphrinta Yasungulwa eFrance ngo-1905 nguHouleg. Kuyisimiso sokunyathelisa esiwusizo esikhulu, lapho ezinye izindawo zepuleti ziphakeme kunezinye futhi yizo ezishiya umbono wazo ephepheni.

Uhlelo luyafana nalolo olusetshenziswa yi-typography, umehluko usezingcwecweni ezisetshenziswayo. Ngenkathi ku-typography ipuleti lingase libe lukhuni kakhulu, izinto ezisetshenziswa ku-flexography, njengoba igama layo liphakamisa, ziyaguquguquka futhi ziyi-rubbery. Eqinisweni, ekuqaleni inqubo yayaziwa ngaphansi kwegama lokuphrinta nge-gum.

Kuyinto indlela esetshenziswa kakhulu yokugxiviza iziqukathi namaphakheji. Ngawo-50, le ndlela yathuthukisa ukunyathelisa ngoyinki otshwala noyinki osuselwe emanzini esikhundleni sokusebenzisa lawo avamile e-aniline, ayenobuthi kakhulu. Kamuva i ukusetshenziswa kwamapuleti asekelwe kuma-photopolymers esikhundleni sezinjoloba, kusho uguquko endleleni.

Imishini

Emkhakheni wokunyathelisa, izakhiwo ezintathu ziyatholakala ezihluke komunye nomunye nokuthi ngamunye ulungisa umshini we-flexo.

Okuyinhloko yilezi: imishini yokunyathelisa ye-drum flexo ephakathi, imishini ye-stack flexo kanye nemishini ye-flexo engaphakathi.

Le mishini yakhiwe: i-anilox roller esiza ukuphrinta okulungile, isistimu yeblade kadokotela enegumbi likayinki elinikeza inani elidingekayo le-pigment ngaphakathi kwerola, isilinda sepuleti okufakwe kulo ipuleti lokuphrinta, isilinda sokuphrinta lapho i-substrate iphumula njengoba ipuleti lokuphrinta liyicindezela, kanye nesistimu ye-inking.

Inqubo

Le nqubo ilula kakhulu njengoba phakathi nenqubo yokunyathelisa uyinki uphonswa nge- Ingaphakathi legumbi likayinki le-doctor blade system esikubalule ngenhla. Ngaphakathi kwegumbi elishiwo, sithola izindwani ezimbili ezithatha uyinki ngenkathi ixhumene nerola le-anilox.

Le roller iyanyakaza futhi ijikeleze ukuze indawo yayo ihlangane nokukhululeka kwamapuleti okuphrinta asesilinda, ngaleyo ndlela idlulise uyinki eqoqwe ama-blade kadokotela.

Izinzuzo nokungalungi

Izinzuzo

Izinzuzo zalolu hlelo lokunyathelisa zibaluleke kakhulu emithonjeni yezindaba noma ephepheni elincintisana emakethe ye-offset.

• Imishini inezindleko eziphansi, okungukuthi, le mishini ishibhile uma siyiqhathanisa ne-offset ne-hollow printing, futhi imiphumela efanayo itholakala kweminye imisebenzi eyenziwayo.
• Ayinabala noma ayishiyi uphawu emhlane njengoba kunjalo umshini ovumelana nezimo naphezu kokukhululeka kwawo okuphezulu.
• Amapuleti nawo ashibhile futhi awabizi, okusho ukuthi izinto zokwakha ishibhile futhi zibiza kahle emisebenzini emincane kuya kwephakathi. Noma kunjalo, asabiza kakhulu kune-offset plate.
• Aqukethe isivinini esikhulu sokuphrinta, lokho kwenza inqubo isheshe futhi ibe lula.
• Kukhona ukuqina okunqumayo ngombala, okungukuthi, isistimu ye-inking ivumela ukulawulwa kombala ukuthi kugcinwe kukho konke ukuphrinta, okuqinisekisa ukwethembeka kokukhiqizwa kwayo.
• Ukuhlukahluka kokukwazi ukuphrinta kuzisekelo ezimunca nezingamunceli, ngaphezu kokukwazi ukusebenzisa amafomethi ahluke kakhulu, kuvumela ulayini wokukhiqiza ukuthi ifanela izinhlobo eziningi zezimakethe.

nebubi

Kunezingqinamba ezimbalwa kakhulu ezikhona ku-flexography, eziningi zazo yilezi:

• Ikhiqiza umphumela we-squash okuphazamisa iphimbo nokumatanisa kombala.
• Izinqumo eziphansi ngenxa yohlobo lwepuleti elisetshenzisiwe, zisho ukuthi ikhwalithi yesithombe ayiphezulu ngokwanele.
• Kukhona i-deformation njengoba inqubo yemibala emine ivame ukuba nemikhawulo ethile.

Aplicaciones

Izicelo ezaziwa kakhulu kulolu hlobo lokuphrinta zivame ukubonakala ngaphezu kwakho konke emikhiqizweni ehlukene yokudla, okungukuthi, kulowo nalowo wokwenziwa kwama-wrappers. Yingakho, njengoba sesishilo ngaphambili, umkhakha wokupakisha. Yingakho ngokuvamile sithola:

• Ukusonga nokupakisha
• Cellophane noma Plastic
• Izinto eziyinkimbinkimbi ezifana ne-tetrabriks
• Izitsha zobisi neziphuzo
• amabhokisi kathayela
• Izimvilophu
• ukupakisha nezimo
• amabhokisi asongekayo
• Ukugoqwa Kwesipho
• ukupakishwa kwe-multilayer
• Izikhwama zamaphepha nezikhwama zepulasitiki
• amabhokisi amaphepha aqinile
• Amaphakheji angawodwana njengezibuko neziqukathi namalebula nemikhiqizo.

Izinkampani zeFlexography

i-diflex

i-diflex yinkampani eyasungulwa ngo-1995 futhi ezinze eMadrid (Spain), yinkampani ephumelelayo, okuthi ngesikhathi esifushane, inkampani izuze idumela lekhwalithi, ukungaguquguquki, izikhathi ezimfushane zokulethwa, izinga eliphezulu lenkonzo kanye nokusha okuqhubekayo.

Yinkampani enombono ocacile kanye nobizo lobuholi obusekela impumelelo yayo kulwazi lwabasebenzi bayo, futhi lokho akukhathazi ukutshala ezindaweni zokusebenza ezinhle kakhulu kanye nengqalasizinda yesimanjemanje.

esko

U-Esko wethula i-HD Flexo emhlabeni wokunyathelisa kwe-flexo, futhi kusukela ngaleso sikhathi izinkampani bezilokhu zisuka ekukhiqizeni ama-gravure. Izinzuzo zinhle kakhulu ukuthi ungazinaki: okokuqala ngqa izimbangi zokuphrinta ze-flexo izinga le-gravure ne-letterpress printing.

Atef

Kuyinkundla evamile yobuchwepheshe yezinkampani zikazwelonke ze-flexography kanye nalo lonke uchungechunge lwenani, ehlinzeka ngawo wonke amathuluzi adingekayo avumela amaphrinta ukuthi enze noma athuthukise umsebenzi wawo ezindaweni nemikhakha ehlukene.

Ukuhlinzeka ngolwazi nolwazi ngezingqungquthela zayo zaminyaka yonke zezobuchwepheshe, ukuqeqeshwa, izihloko zezobuchwepheshe, imihlangano evamile, izincwadi zezindaba zanyanga zonke kanye ne-FTA Europe, i-Flexographic Technical Association, emele izithakazelo ezivamile zemboni yokunyathelisa ye-flexographic yaseYurophu.

Fina

I-Fina inemvelaphi yayo ebhizinisini lomndeni i-Rotogravure Fina, eyasungulwa ngo-1974, igxile ekunyatheliseni imidiya eguquguqukayo yokupakishwa kwabathengi. namuhla kuhle, inikeza izixazululo ezithuthukisiwe nezenziwe ngezifiso, ku-gravure kanye ne-flexography, ezinkampanini zokudla ezihamba phambili neminye imikhakha.

Ngaphezu kwalokho, inobukhona obubalulekile bamazwe ngamazwe, ngokuthunyelwa kwamanye amazwe eJalimane, eFrance, ePortugal nase-United Kingdom. Ukuqamba izinto ezintsha, ubuchwepheshe besimanje kanye nenqubo ehamba phambili, ngenhlonipho enkulu ngendawo ezungezile, izihluthulelo zefilosofi ye-Fina.

Isiphetho

Uma usufike ekugcineni kokuthunyelwe, singangeza kuphela ukuthi sithemba ukuthi ufunde kabanzi mayelana nalolu hlelo lokuphrinta oselusetshenziswe iminyaka embalwa futhi lunomlando.

Izinkampani eziningi zibheja ku-flexography njengendlela eyinhloko yokukhiqiza, njengoba kuwumsebenzi odingeka kakhulu emazweni ahlukene. Ukwengeza, imikhiqizo eminingi esiyithengayo nesiyidlayo osukwini lwethu nosuku, ekupakishweni kwayo ngakunye noma kuma-wrappers, kuye kwenziwa inqubo ehlukile ye-flexography.
