Esi siphene siyingxaki ngokukodwa ekupakisheni izicelo apho isibheno esibonakalayo sibaluleke kakhulu kwisibheno somthengi.

Ukuxhaphaka kwePinholing kwiFlexographic Printing

I-Pinholing ngumba oqhelekileyo kushicilelo lwe-flexographic ngenxa yezinto ezifana nesantya sokumisa i-inki, umgangatho we-substrate surface, kunye nokusetha izixhobo. Kwenzeka xa i-inki ingaphumeleli ukugubungela ngokupheleleyo i-substrate, ishiya i-voids encinci okanye imingxuma. Ukugcinwa okufanelekileyo kunye nohlengahlengiso kunokunceda ukunciphisa ukwenzeka kwayo.

Iimbangela zePinholing kwiFlexographic Printing

Imiba eNxulumene ne-Ink

• Isantya sokumisa ngokukhawuleza kwee-inki : Xa ii-inki zomile ngokukhawuleza, zisenokungagqumeki ngokupheleleyo i-substrate, ekhokelela kwi-pinholing. Oku kunokubangelwa ngamaqondo obushushu aphezulu okanye ukwakheka kwe-inki engafanelekanga.

• I-viscosity ephezulu yee-inks : Ii-inks ezityebileyo kakhulu zinokubangela ukugubungela ukungalingani kunye nokudluliselwa okungahambi kakuhle kwi-substrate, ukudala i-pinholes.

• Ubukho bokungcola okanye iinqununu kwiinki : Ukungcola kwi-inkino kunokuphazamisa inkqubo yokushicilela kwaye kubangele i-voids encinci kwindawo eprintiweyo.

Imiba eNxulumene nePlate

• Izitenxo okanye umonakalo kwindawo yepleyiti : Iipleyiti zokushicilela ezonakalisiweyo okanye ezingalinganiyo zinokuthintela ukuhanjiswa kwe-inki efanelekileyo, okubangela ukuba i-pinholing.

• Ubunzulu bechaphaza obungafanelekanga okanye imilo kwiipleyiti zokushicilela : Amachaphaza angekho nzulu kakhulu okanye aneemilo ezingaqhelekanga asenokungabambeli i-inki eyaneleyo, ekhokelela ekugqunyweni okungaphelelanga.

Imiba eNxulumene neZixhobo

• Uxinzelelo lwengqondo engalinganiyo : Uxinzelelo olungahambelaniyo phakathi kwepleyiti yokushicilela kunye ne-substrate inokubangela ukuba ezinye iindawo zifumane inki eyaneleyo, zenze i-pinholes.

• Izicwangciso ezingafanelekanga kwizixhobo zokumisa : Izixhobo zokomisa ezibekwe phezulu kakhulu okanye eziphantsi kakhulu zinokuchaphazela ukomiswa kwe-inki kunye nokudluliselwa, okukhokelela kwi-pinholing.

Imiba eNxulumene neSubstrate

• Ukungahambelani phakathi koxinzelelo lomphezulu we-substrate kunye ne-inki : Ukuba ukuxinezeleka komphezulu we-substrate akuhambelani ne-inki, i-inki ayinako ukusasazeka ngokulinganayo, okukhokelela kwimingxuma yokukhonkotha.

• Ubukho bothuli, i-oyile, okanye ezinye izinto ezingcolileyo kwi-substrate surfaces : Ukungcola kwi-substrate kunokuthintela inki ukuba ibambelele ngokufanelekileyo, ibangele i-voids kwindawo eprintiweyo.

Izisombululo zokuPinholing kwiFlexographic Printing

Ukulungelelanisa iiPropati ze-Ink

• Ukuguqula iifom ze-inki : Lungisa iifom ze-inki ukuze ufezekise isantya esomileyo kunye ne-viscosity. Oku kuqinisekisa ugqithiselo lwe-inki olufanelekileyo kwaye kunciphisa ukwenzeka kwe-pinholing.

• Ukongeza i-retarders okanye i-thinners : Ukongeza i-retarders okanye i-thinners inokunciphisa ukoma kwe-inki, ukuyikhusela ukuba yome ngokukhawuleza kwaye ibangele i-pinholes.

• Ukuqinisekisa ukucoceka kwe-inki : Sebenzisa ii-inki ezikumgangatho ophezulu kwaye uqinisekise ukuba azinangcoliseko. Ukucoca rhoqo izikhongozeli ze-inki kunye neenkqubo zokuhanjiswa ukugcina ubunyulu be-inki.

Ukuphucula iipleyiti zoShicilelo

• Ukuhlola kunye nokutshintsha iipleyiti ezonakalisiweyo : Hlola rhoqo iipleyiti zokushicilela umonakalo okanye izitenxo. Buyisela iipleyiti ezonakalisiweyo ukuqinisekisa ukuba ugqithiso lwe-inki.

• Ukukhetha izixhobo zeplate ezifanelekileyo : Khetha izinto zeplate ezibonelela ngokugqithiswa kakuhle kwe-inki kwaye zixhathise ukuvuvukala kunye nomonakalo. Cinga ukusebenzisa imikhono ye-elastomer enganyangekiyo ukuze usebenze ngcono.

ULondolozo lweZixhobo kunye noLungiso
