I-Flexo, njengoko igama libonisa, i-flexographic plate yokushicilela eyenziwe nge-resin kunye nezinye izinto. Bubuchwephesha bokushicilela nge letterpress. Iindleko zokwenza iipleyiti ziphantsi kakhulu kunezo zentsimbi zokuprinta iipleyiti ezifana ne-intaglio copper plates. Le ndlela yokushicilela yacetywa phakathi kwinkulungwane edlulileyo. Nangona kunjalo, ngelo xesha, iteknoloji ye-inki exhasayo yamanzi ayizange iphuhliswe kakhulu, kwaye iimfuno zokukhuselwa kwendalo azizange zikhathazeke ngelo xesha, ngoko ke ukuprintwa kwezinto ezingabonakaliyo akuzange kukhuthazwe.

Nangona ukuprintwa kwe-flexographic kunye noshicilelo lwe-gravure ngokusisiseko ziyafana kwinkqubo, zombini zikhulula, zijika, zigqithise inki, zomiswe, njl., kodwa kusekho umahluko omkhulu kwiinkcukacha phakathi kwezi zimbini. Ngaphambili, ii-inki ze-gravure kunye ne-solvent-based ineziphumo ezicacileyo zokuprinta. Kungcono kunokushicilela i-flexographic, ngoku kunye nophuhliso olukhulu lwee-inki ezisekelwe kumanzi, ii-inks ze-UV kunye nezinye iitekhnoloji ze-inki ezinobume bendalo, iimpawu zokushicilela i-flexographic ziqala ukubonakala, kwaye azikho ngaphantsi kwe-gravure yokushicilela. Ngokubanzi, ukuprintwa kwe-flexographic kunezi mpawu zilandelayo:

1. Iindleko eziphantsi

Iindleko zokwenza ipleyiti ziphantsi kakhulu kune-gravure, ngakumbi xa uprinta kwiibhetshi ezincinci, i-gap inkulu.

2. Sebenzisa i-inki encinci

Ukuprintwa kwe-flexographic kwamkela i-flexographic plate, kwaye inkino idluliselwa nge-anilox roller, kwaye ukusetyenziswa kwe-inkino kuncitshiswe ngaphezu kwe-20% xa kuthelekiswa ne-intaglio plate.

3. Isantya sokushicilela sikhawuleza kwaye ukusebenza kakuhle kuphezulu

Umatshini wokushicilela we-flexographic kunye ne-inki ephezulu esekelwe emanzini unokufikelela ngokulula kwisantya esiphezulu seemitha ezingama-400 ngomzuzu, ngelixa ukuprintwa kwe-gravure eqhelekileyo kunokufikelela kuphela kwi-150 yeemitha.

4. Ukulungeleka ngakumbi kokusingqongileyo

Ekushicileleni i-flexo, ii-inki ezisekelwe emanzini, ii-inks ze-UV kunye nezinye i-inks ezihambelana nokusingqongileyo zisetyenziswa ngokuqhelekileyo, ezihambelana nokusingqongileyo kune-solvent-based based inki esetyenziswa kwi-gravure. Phantse akukho kukhutshwa kwe-VOCS, kwaye inokuba yinqanaba lokutya.

Iimpawu zoshicilelo lwegravure

1. Iindleko eziphezulu zokwenza iipleyiti

Kwiintsuku zokuqala, iiplate ze-gravure zenziwe ngokusebenzisa iindlela zokubola kweekhemikhali, kodwa umphumo wawungekho kakuhle. Ngoku iipleyiti ze-laser zingasetyenziswa, ngoko ke ukuchaneka kuphezulu, kwaye iipleyiti zokushicilela ezenziwe ngobhedu kunye nezinye izinyithi zomelele ngaphezu kweepleyiti ze-resin eziguquguqukayo, kodwa iindleko zokwenza iipleyiti nazo ziphezulu. Utyalo-mali lokuqala oluphezulu, olukhulu.

2. Ukuchaneka okungcono kokuprinta kunye nokuhambelana

Ipleyiti yokushicilela yesinyithi ifaneleke ngakumbi ukuprintwa ngobuninzi, kwaye inokuhambelana okungcono. Ichatshazelwa kukwandiswa kwe-thermal kunye nokunciphisa kwaye incinci

3. Ukusetyenziswa kwe-inki enkulu kunye neendleko eziphezulu zokuvelisa

Ngokubhekiselele kugqithiso lwe-inki, ukuprintwa kwegravure kudla i-inki eninzi, nto leyo eyandisa iindleko zemveliso.
