I-Flexo, njengoko igama lisitsho, yipleyiti yokuprinta ye-flexographic eyenziwe nge-resin nezinye izinto. Yiteknoloji yokuprinta ye-letterpress. Ixabiso lokwenza iipleyiti liphantsi kakhulu kuneleepleyiti zokuprinta zesinyithi ezifana neepleyiti zobhedu ze-intaglio. Le ndlela yokuprinta yacetywayo phakathi kwinkulungwane edlulileyo. Nangona kunjalo, ngelo xesha, iteknoloji ye-inki exhasayo esekwe emanzini yayingekaphuhliswa kakhulu, kwaye iimfuno zokukhusela okusingqongileyo zazingenamsebenzi kangako ngelo xesha, ngoko ke ukuprintwa kwezinto ezingafunxiyo akuzange kukhuthazwe.

Nangona ukuprinta nge-flexographic kunye nokuprinta nge-gravure kufana kakhulu xa kusenziwa, zombini ziyakhulula, ziyajikajika, ziyadlulisa i-inki, ziyayomisa, njl.njl., kodwa kusekho umahluko omkhulu kwiinkcukacha phakathi kwezi zimbini. Kwixesha elidlulileyo, i-inki ezisekwe kwi-gravure kunye ne-solvent zineziphumo ezicacileyo zokuprinta. Kungcono kunokushicilela nge-flexographic, ngoku ngophuhliso olukhulu lwee-inki ezisekwe emanzini, ii-inki ze-UV kunye nezinye iiteknoloji ze-inki ezinobuhlobo nokusingqongileyo, iimpawu zokuprinta nge-flexographic ziqala ukubonakala, kwaye azikho ngaphantsi kokuprinta nge-gravure. Ngokubanzi, ukuprinta nge-flexographic kuneempawu ezilandelayo:

1. Ixabiso eliphantsi

Ixabiso lokwenza iipleyiti liphantsi kakhulu kunelo legravure, ingakumbi xa kuprintwa ngeebhetshi ezincinci, umsantsa mkhulu kakhulu.

2. Sebenzisa i-inki encinci

Ukuprintwa kwe-flexographic kusebenzisa ipleyiti ye-flexographic, kwaye i-inki idluliselwa nge-anilox roller, kwaye ukusetyenziswa kwe-inki kuncitshiswa ngaphezulu kwe-20% xa kuthelekiswa nepleyiti ye-intaglio.

3. Isantya sokuprinta siyakhawuleza kwaye ukusebenza kakuhle kuphezulu

Umatshini wokuprinta we-flexographic one-inki esemgangathweni osekelwe emanzini unokufikelela ngokulula kwisantya esiphezulu seemitha ezingama-400 ngomzuzu, ngelixa ushicilelo oluqhelekileyo lwegravure ludla ngokufikelela kwiimitha ezili-150 kuphela.

4. Inobuhlobo ngakumbi nokusingqongileyo

Kwiprinta ye-flexo, ii-inki ezisekelwe emanzini, ii-inki ze-UV kunye nezinye ii-inki ezinobuhlobo nokusingqongileyo zihlala zisetyenziswa, ezinokuba nobuhlobo nokusingqongileyo kunee-inki ezisekelwe kwisinyibilikisi ezisetyenziswa kwi-gravure. Akukho phantse i-VOCS emission, kwaye inokuba yeyodidi lokutya.

Iimpawu zokuprinta i-gravure

1. Ixabiso eliphezulu lokwenza iipleyiti

Kwimihla yokuqala, iipleyiti zegravure zazisenziwa kusetyenziswa iindlela zokubola kweekhemikhali, kodwa isiphumo sasingesihle. Ngoku iipleyiti zelaser zingasetyenziswa, ngoko ke ukuchaneka kuphezulu, kwaye iipleyiti zokuprinta ezenziwe ngobhedu nezinye izinyithi zihlala ixesha elide kuneepleyiti zeresin eziguquguqukayo, kodwa ixabiso lokwenza iipleyiti nalo liphezulu. Utyalo-mali olukhulu lokuqala.

2. Ukuchaneka okungcono kokuprinta kunye nokuhambelana

Ipleyiti yokuprinta yesinyithi ifanelekile ngakumbi ekuprintweni ngobuninzi, kwaye inobungqingqwa obungcono. Ichaphazeleka kukwanda kobushushu kunye nokucutheka kwaye incinci xa ithelekiswa.

3. Ukusetyenziswa kwe-inki enkulu kunye neendleko eziphezulu zemveliso

Ngokuphathelele ukudluliselwa kweyinki, ukuprinta igravure kusebenzisa i-yinki eninzi, nto leyo enyusa kakhulu iindleko zokuvelisa.
