Umehluko phakathi komshini wokuphrinta we-FLEFO nomshini wokuphrinta we-rotogravava.

I-Flexo, njengoba igama libonisa, iyipuleti lokuphrinta le-flezographic elenziwe nge-resin nezinye izinto. Kuyinto ubuchwepheshe bokuphrinta we-letterpress. Izindleko zokwenza ipuleti ziphansi kakhulu kunalezo zamapuleti wokuphrinta wensimbi afana namapuleti ethusi we-Intaglio. Le ndlela yokuphrinta yahlongozwa phakathi kwekhulu leminyaka elidlule. Kodwa-ke, ngaleso sikhathi, ubuchwepheshe obusekelwe be-Inkyinki osuselwa emanzini bebengakaze bathuthukiswe kakhulu, futhi izidingo zokuvikelwa kwemvelo bezingakhathazeki kangako ngaleso sikhathi, ngakho-ke ukunyatheliswa kwezinto ezingezona ezingase kuhlolwe akuzange kugqugquzelwe.

Yize ukuphrinta okuguquguqukayo kanye nokuphrinta okungaguquguquki ngokufanayo ngokufanayo kwenqubo, zombili zingenakugwenywa, ziveza umoya, ukudluliselwa kwe-ink, ukomisa, kepha kukhona umehluko omkhulu ngemininingwane ephakathi kwalokhu okubili. Esikhathini esedlule, ama-inks asuselwa ku-solvent kanye nemiphumela ebonakalayo yokuphrinta. Kungcono kunokuphrinta okuguquguqukayo, manje ngokuthuthuka okukhulu kwama-inks asuselwa emanzini, ama-inks e-UV kanye nezinye ubuchwepheshe be-Ink bemvelo, izici zokuphrinta kwe-flezographic, futhi azitholi phansi ukuphrinta okubalekayo. Ngokuvamile, ukuphrinta okuguquguqukayo kunezimpawu ezilandelayo:

1. Izindleko eziphansi

Izindleko zokwenziwa kwepuleti ziphansi kakhulu kunalezo ezibangelwa, ikakhulukazi lapho ziphrinta ngamabhethri amancane, igebe likhulu.

2. Sebenzisa uyinki omncane

Ukuphrinta kwe-flezographic kuthathwa ipuleti ye-flezographic, futhi uyinki udluliswa nge-anilox roller, futhi ukusetshenziswa kwe-ink kuncishiswa ngaphezu kwama-20% uma kuqhathaniswa neplate ye-infaglio.

3. Ijubane lokuphrinta lishesha futhi ukusebenza kahle kuphakeme

Umshini wokuphrinta we-flezographic onama-inki asezingeni eliphakeme asuselwa emanzini ungafinyelela kalula isivinini esiphezulu samamitha angama-400 ngomzuzu, ngenkathi ukuphrinta okuvamile kwamafuvu ngokuvamile kungahlala kufinyelela kumamitha ayi-150 kuphela.

4. Ngini nemvelo enobungane

Ekushicileleni kwe-FLEFE, ama-inks asuselwa emanzini, ama-incks e-UV kanye nezinye izinto ezinobungani zemvelo zisetshenziswa ngokuvamile, ezinobungane kakhulu kune-inks esekelwe e-solvent esetshenziselwa ama-guren. Cishe akukho ukuphuma kwama-vocs, futhi kungaba grade lokudla.

Izici Zokuphrinta Okungaphenduli

1. Izindleko eziphakeme zokwenza ipuleti

Ezinsukwini zokuqala, kwenziwa amapuleti amafuvu asebenzisa izindlela zokugqwala kwamakhemikhali, kodwa umphumela wawungemuhle. Manje kungasetshenziswa amapuleti e-laser, ngakho-ke ukunemba kuphakeme, futhi amapuleti okunyathelisa okwenziwe ngethusi nezinye izinsimbi zihlala isikhathi eside kune-resin amapuleti, kepha izindleko zokwenza ipuleti ziphakeme. Ukutshala imali okuphezulu, kokuqala.

2. Ukunemba okungcono kokuphrinta nokungaguquguquki

Ipuleti lokuphrinta lensimbi lilungele kakhulu ukuphrinta okuningi, futhi linokuvumelana okungcono. Kuyathinteka ekunwetshisweni kwe-thermal kanye ne-contraction futhi kuncane

I-3. Ukusetshenziswa okukhulu kwe-ink kanye nezindleko eziphezulu zokukhiqiza

Ngokuya kwe-Ink Transfer, ukuphrinta okungaba nengcwabeni kudla i-ink ethe xaxa, lapho kukhulisa izindleko zokukhiqiza.
