I-Flexo, njengoba igama lisho, iyipuleti lokunyathelisa le-flexographic elenziwe nge-resin nezinye izinto. Iwubuchwepheshe bokunyathelisa nge-letterpress. Izindleko zokwenza amapuleti ziphansi kakhulu kunezamapuleti okunyathelisa ensimbi njenge-intaglio copper plates. Le ndlela yokunyathelisa yaphakanyiswa maphakathi nekhulu leminyaka elidlule. Kodwa-ke, ngaleso sikhathi, ubuchwepheshe be-inki obusekelwe emanzini obusekelayo babungakathuthukiswa kakhulu, futhi izidingo zokuvikela imvelo zazingakhathalekile kangako ngaleso sikhathi, ngakho-ke ukunyatheliswa kwezinto ezingamunci akuzange kukhuthazwe.

Nakuba ukuphrinta kwe-flexographic kanye nokuphrinta kwe-gravure kufana kakhulu lapho kuqhubeka, kokubili kuyaqaqa, kuyagoqa, kuyadluliswa kwe-inki, kuyawomisa, njll., kodwa kusenomehluko omkhulu emininingwaneni phakathi kwalokhu okubili. Esikhathini esidlule, i-ink esekelwe ku-gravure kanye ne-solvent inemiphumela yokuphrinta esobala. Kungcono kunokuphrinta kwe-flexographic, manje ngentuthuko enkulu ye-ink esekelwe emanzini, i-ink ye-UV kanye nobunye ubuchwepheshe be-inki obunobungani nemvelo, izici zokuphrinta kwe-flexographic seziqala ukubonakala, futhi aziphansi kunokuphrinta kwe-gravure. Ngokuvamile, ukuphrinta kwe-flexographic kunezici ezilandelayo:

1. Izindleko eziphansi

Izindleko zokwenza amapuleti ziphansi kakhulu kunezo zokufaka i-gravure, ikakhulukazi uma kunyatheliswa ngamaqoqo amancane, igebe likhulu kakhulu.

2. Sebenzisa uyinki omncane

Ukuphrinta kwe-flexographic kusebenzisa ipuleti le-flexographic, bese uyinki idluliselwa nge-anilox roller, futhi ukusetshenziswa kweyinki kuncishiswe ngaphezu kuka-20% uma kuqhathaniswa nepuleti le-intaglio.

3. Isivinini sokuphrinta siyashesha futhi ukusebenza kahle kuphakeme

Umshini wokunyathelisa we-flexographic onoyinki osezingeni eliphezulu osekelwe emanzini ungafinyelela kalula isivinini esiphezulu samamitha angu-400 ngomzuzu, kuyilapho ukunyathelisa okuvamile kwe-gravure kuvame ukufinyelela amamitha angu-150 kuphela.

4. Okunobungani nemvelo kakhulu

Ekuphrinteni kwe-flexo, i-inki ezisekelwe emanzini, i-inki ze-UV kanye nezinye i-inki ezinobungani nemvelo zivame ukusetshenziswa, ezingobungani nemvelo kakhulu kune-inki ezisekelwe ku-solvent ezisetshenziswa ekugayweni. Cishe akukho ukukhishwa kwe-VOCS, futhi kungaba yizinga lokudla.

Izici zokuphrinta kwe-gravure

1. Izindleko eziphezulu zokwenza amapuleti

Ezinsukwini zokuqala, amapuleti okugcoba ayenziwa kusetshenziswa izindlela zokugqwala kwamakhemikhali, kodwa umphumela wawungemuhle. Manje amapuleti e-laser angasetshenziswa, ngakho-ke ukunemba kuphakeme, futhi amapuleti okunyathelisa enziwe ngethusi nezinye izinsimbi ahlala isikhathi eside kunamapuleti e-resin aguquguqukayo, kodwa izindleko zokwenza amapuleti nazo ziphakeme. Ukutshalwa kwezimali kokuqala okuphezulu, okukhulu.

2. Ukunemba okungcono kokuphrinta kanye nokuvumelana

Ipuleti lokuphrinta lensimbi lifaneleka kakhulu ekuphrinteni ngobuningi, futhi linokuqina okungcono. Lithinteka ukwanda nokuncipha kokushisa futhi lincane kakhulu.

3. Ukusetshenziswa kakhulu kweyinki kanye nezindleko zokukhiqiza eziphezulu

Ngokuphathelene nokudluliselwa kweyinki, ukuphrinta kwe-gravure kudla i-yinki eningi, okwandisa cishe izindleko zokukhiqiza.
