Ushicilelo lwesikrini ukumenyesa kwendawo

Ushicilelo lwesikrini luneempawu zokhutshelo lwe-inki ephezulu, umaleko we-inki eshinyeneyo kunye nengqiqo eyomeleleyo enemilinganiselo emithathu.Ukucwenga kunye nepleyiti yesikrini kufuneka kukhethwe ngokubanzi i-200 ~ 300 yesikrini se-mesh (kwisiphumo sendawo ye-matte yombala we-glazing, inombolo ye-mesh iphantsi), i-tension network tension in 20 ~ 25N/CM.Ngenxa yokuba utyalo-mali lwezixhobo alukho lukhulu.Iincwadi ezininzi kunye neefektri zokupakisha ekwandeni kweshishini leglazing yendawo, zikhethwa ukuprinta isikrini.

Ukukhenkceza kwendawo yeFlexo

Ukuprintwa kwe-Flexographic kubonakaliswe ngokukwazi ukwenza iingubo ezityebileyo kwinkqubo elula.Ke ngoko, ithandwa kakhulu kwi-UV glazing.I-Flexographic printing local glazing yahlulwe kwi-flexographic printing glazing kunye ne-flexographic printing glazing ekhethekileyo, kunye nesicatshulwa esilula kunye nomfanekiso kusetyenziswa irabha ekroliweyo ye-letterpress.

I-Flexographic yoshicilelo lwe-glazing yasekhaya ifanelekile kwi-glazing engaxhunyiwe kwi-intanethi okanye kwi-intanethi.I-Adopt flexographic printing glazing method, isebenzisana ne-anilox roller kunye ne-cavity type scraper, inokulawula ngokuchanekileyo ubuninzi be-glazing, umgangatho we-glazing uzinzile.

Ukukhenkceza kwendawo yeGravure

Ushicilelo lweGravure ngenxa yoshicilelo lwe-inki yoshicilelo lungqindilili kwaye igubu leconcave loshicilelo lokumelana liphezulu kwi-UV ye-glaising yendawo nayo ineenzuzo, ngakumbi ukuvela komatshini wokushicilela we-sheet-fed we-sheet-fed for the development of glaising yasekhaya uye wadlala indima ekukhuthazeni.Kodwa ngenxa yeendleko eziphezulu ze-seihan zisetyenziswa ikakhulu kwishishini elide lokutshiza.

Ezinye iindlela zeglazing yendawo

Phambi kokufika kwevanishi ye-UV, akukho mntu unokusebenzisa ushicilelo lwe-offset ukukhenkceza kuba umaleko we-inki yokushicilela ubhityile kakhulu.Kwaye ivanishi ye-UV ngenxa yefilimu eshinyeneyo, iglosi ephezulu kwaye inenzuzo yokuchaneka okuphezulu kokuchaneka kwe-UV yasekhaya ikwanezicelo ezithile kodwa isetyenziselwa ukukhenkceza kwi-intanethi.

Ukusuka kwindlela yemveliso, umatshini wokukhenkceza we-UV wasekhaya unokwahlulwa ube yiglazing engaxhunyiwe kwi-intanethi kunye ne-intanethi.Ukukhanya okungaxhunyiwe kwi-intanethi kubhekisela ekushicileleni, ukukhanya kwisixhobo esikhethekileyo, ngokulandelelana, kufuneka kusetyenziswe umatshini okhethekileyo we-glazing okanye i-calender.Ukukhenkceza ngaphandle kweintanethi, kuba into eprintiweyo inokomiswa ngokupheleleyo, ngoko ke inokufumana iglosi ephezulu kunokukhanya kwe-intanethi.Ukongeza, ukuguquguquka kwemveliso ye-glazing off-line.

Utyalo-mali oluncinci kwizixhobo.Ukukhenkceza kwi-intanethi kubhekiselele kushicilelo kunye nokukhenkceza okwenziwa kumgca omnye wemveliso, oko kukuthi, ukongeza ukukhenkceza kunye nezixhobo zokunyanga ze-UV kumatshini wokushicilela.Ukwenza ukuba umba oshicilelweyo ukhazimliswe ngqo emva kokushicilelwa.

Itekhnoloji entsha ye-UV yendawo

①Itekhnoloji ye-inki exutyiweyo

Ngenxa yokuba ushicilelo lwe-UV okanye ukukhenkceza kwe-UV akufanelanga ukusetyenziswa kwindawo efunxayo eyomeleleyo ye-substrate, kunye namahlwempu kumphezulu we-inki yokuncamathelisa, ngoko ke uninzi lwemfuno yokukhenkceza kwe-UV kwi-Intanethi, ukuba zonke zisebenzisa i-inki yoshicilelo ye-UV, ibotshelelwe. ukwandisa iindleko: ukuba usebenzisa ushicilelo lwe-inki eqhelekileyo, ukudalwa kwe-glazing egqunyiweyo okanye ebanzi, ethintele ngokungathandabuzekiyo ukusetyenziswa kwe-offset yoshicilelo lwe-intanethi.

Itekhnoloji ye-inki exutyiweyo iyasebenza ukusombulula le ngxaki yebhotile.Idibanisa iingenelo ze-inki ye-UV kunye ne-inki yesintu ngokwemigaqo yokusebenza, oko kukuthi, iingenelo zokunyanga ukukhanya kunye ne-oxidation polymerization yokomisa, iphucula isiphumo se-synergistic ye-inki yomphezulu kunye ne-UV ivanishi, kwaye ivula indlela yoshicilelo lwe-offset kwi-line glazing.

② ukubengezela umva

Ipro-cure inxulumene nokukhenkceza kwemveli kwalapha.Thatha indlela yemveli yokukhenkceza (i-flexographic printing screen printing or printing gravure) ukwenzela ukukhenkceza kwendawo, ekugqibeleni kufuneka isebenzise ipleyiti yokubeka ipleyiti yalapha ekhaya, ukuze kuphunyezwe isiphumo esimahluko esiphezulu sokubhaliweyo kwasekhaya kunye nomfanekiso, ngoko ukukhazimla kunye nokushicilela ukuchaneka okungaphezulu ngundoqo. kwinkqubo yokukhenkceza.Inkqubo ye-glazing eguqukayo iphula le mithetho ingentla, ukwenzela ukuba ingxaki yokubhalisa isonjululwe.

③Ukukhanya kweUV kwi-Intanethi

I-intanethi ye-glazing yokushicilela i-flexographic kunye noshicilelo lwe-gravure, akuzange kuthiwe iteknoloji entsha, kunye noluhlu olubanzi lwezicelo, ukuchaneka kokuprinta kunye nokuprintwa kwe-offset yesantya esiphezulu, kukwahlulahlulo kunye neenkonzo ezongeziweyo zexabiso eziqaliswe ngeengcamango ezintsha ze-glazing. iteknoloji.

Kukho iindlela ezine eziphambili zokukhanya kwe-UV kwi-intanethi ezisetyenzisiweyo:

I-inki ye-UV + i-UV glazing;

I-inki exubeneyo + i-UV glazing;

I-inki ye-UV + i-oyile ye-OP + i-UV glazing (i-reverse glazing);

I-inki eqhelekileyo + ukukhenkceza kabini (ukukhenkceza okuphuma emanzini + ukukhazimla kweUV).

3. Imiba efuna ingqalelo

1) Iimfuno zokuprinta izongezo ze-inki.

Ukuba ukukhenkceza kwe-UV yendawo kuthe ngqo kumphezulu weemveliso zoshicilelo, i-inki yoshicilelo ayifanele yongeze okanye yongeze iintlobo ngeentlobo zezongezo kangangoko kunokwenzeka, njenge-adhesive yokususa i-adhesive, i-oyile ye-inki, ukuze ingachaphazeli i-polarity yomhlaba. Umaleko we-inki, okukhokelela kwi-oyile yexesha elikhanyayo kunye ne-inki encamathelayo ngokukhawuleza, i-oyile ekhanyayo kulula ukuwa, ukuze ichaphazele kakhulu isiphumo sokukhenkceza.

2) Iimfuno zokutshiza umgubo wokutshiza.

Ubungakanani bomgubo wokutshiza kufuneka ube mncinci.Isixa esikhulu somgubo wokutshiza siya kwenza umaleko womgubo phezu komhlaba woshicilelo, okubangela ukuba umaleko we-oyile ye-UV ungadityaniswa ngokuqinileyo kumaleko we-inki, kulula ukuwa, ubonisa iqhekeza lenkungu yelifu, echaphazela kakhulu isiphumo seglazing.Ukuba ubungakanani bepowder alilawulwa kakuhle ngexesha lokushicilela, i powder kufuneka isuswe ngokuxubha ngesandla xa kuyimfuneko.

3) Iimfuno zokuxinana komphezulu weemveliso ezigqunyiweyo.

Kwimfuno yemveliso ye-UV yendawo yokubeka i-UV emva kokugquma, kungcono ukusebenzisa amacala omabini efilimu emva konyango lwe-corona, oko kukuthi, ukuxinana komphezulu kumacala omabini efilimu ukufikelela ngaphezu kwe-38Mn / m, ukuze kuqinisekiswe ukuba I-varnish ye-UV inokudityaniswa ngokuqinileyo kwifilimu.Ngexesha elifanayo, khangela kwakhona ifilimu esetyenzisiweyo.
