Yintoni umahluko phakathi kwe-UV Varnishing, i-varnishing kunye ne-laminating?

Abathengi badla ngokudideka ngeendlela ezahlukeneyo zokugqiba ezinokusetyenziswa kwizinto zokuprinta. Ukungazi okulungileyo kunokubangela iingxaki ngoko ke kubalulekile ukuba xa uodola uxelele iprinta yakho into oyifunayo.

Ngoko ke, yintoni umahluko phakathi kwe-UV Varnishing, i-varnishing kunye ne-laminating? Kukho iintlobo ezahlukeneyo ze-varnish ezinokusetyenziswa ekuprinteni, kodwa zonke zineempawu ezifanayo. Nazi izikhokelo ezimbalwa ezisisiseko.

I-varnish yonyusa ukufunxwa kombala

Ziyayikhawulezisa inkqubo yokomisa.

I-varnish inceda ukuthintela i-inki ukuba ingakhuhli xa iphepha liphathwa.

Iivarnish zisetyenziswa rhoqo kwaye ngempumelelo kumaphepha agqunywe ngepeyinti.

IiLaminate zilungele ukukhuselwa

Ukutywina koomatshini

Itywina lomatshini luphawu olusisiseko, kwaye alubonakali kangako olusetyenziswa njengenxalenye yenkqubo yokuprinta okanye ngaphandle kwe-intanethi emva kokuba iprojekthi iphumile kwi-press. Ayichaphazeli inkangeleko yomsebenzi, kodwa njengoko ivala i-inki phantsi kwengubo ekhuselayo, iprinta akufuneki ilinde ixesha elide ukuba umsebenzi wome ngokwaneleyo ukuba iphathwe. Ihlala isetyenziswa xa kusenziwa ushicilelo olukhawulezayo olufana namaphecana amaphepha e-matt kunye ne-satin, njengoko i-inki zoma kancinci kwezi zinto. Iingubo ezahlukeneyo ziyafumaneka kwiingubo ezahlukeneyo, imibala, ubume kunye nobukhulu, ezinokusetyenziselwa ukulungisa inqanaba lokhuseleko okanye ukufezekisa iziphumo ezahlukeneyo ezibonakalayo. Iindawo ezigqunywe kakhulu yi-inki emnyama okanye eminye imibala emnyama zihlala zifumana uphahla olukhuselayo lokukhusela kwiminwe, ebonakala ngaphandle kwemvelaphi emnyama. Iingubo zikwasetyenziswa kwiimagazini nakwiingxelo kunye nakwezinye iimpapasho eziphathwa gadalala okanye rhoqo.

Iingubo zolwelo zezona ndlela zixhaphakileyo zokukhusela iimpapasho ezishicilelweyo. Zibonelela ngokhuseleko olulula ukuya koluphakathi ngexabiso eliphantsi. Kusetyenziswa iintlobo ezintathu eziphambili zeengubo:

I-Varnish

I-varnish sisigqubuthelo solwelo esisetyenziswa kumphezulu oprintiweyo. Ikwabizwa ngokuba sisigqubuthelo okanye isitywino. Ihlala isetyenziselwa ukuthintela ukukhuhla okanye ukukrwela kwaye idla ngokusetyenziswa kwisitokhwe esigqunyiweyo. I-varnish okanye i-varnish eprintiweyo sisigqubuthelo esicacileyo esinokucutshungulwa njenge-inki kwiimashini zokushicilela (zokungafakwa). Inomxube ofanayo ne-inki kodwa ayinayo nayiphi na i-pigment yombala. Kukho iintlobo ezimbini.

I-Varnish: Ulwelo olucacileyo olusetyenziswa kwiindawo eziprintiweyo ukuze kubonakale kwaye kukhuselwe.

Ulwelo olugqunywe nge-UV: I-laminate yolwelo ibotshelelwe kwaye inyangwe ngokukhanya kwe-ultraviolet. Inobuhlobo nokusingqongileyo.

Ukukhanya kwe-Ultraviolet. Inokuba yingubo ekhazimlayo okanye e-matt. Ingasetyenziswa njengesigqubuthelo samachaphaza ukugxininisa umfanekiso othile kwiphepha okanye njengesigqubuthelo samachaphaza. Isigqubuthelo se-UV sinika ukhuseleko olungaphezulu kunye nokukhanya ngaphezu kwesigqubuthelo samachaphaza okanye amanzi. Ekubeni inyangwa ngokukhanya kungekhona ngobushushu, akukho zinyibilikisi zingena emoyeni. Nangona kunjalo, kunzima ukuziphinda-phinda kunezinye izigqubuthelo. Isigqubuthelo se-UV sisetyenziswa njengomsebenzi wokugqiba owahlukileyo njengesigqubuthelo samachaphaza okanye (sisetyenziswa ngokuprinta kwesikrini) njengesigqubuthelo samachaphaza. Khumbula ukuba esi sigqubuthelo sinzima sinokuqhekeka xa sichongiwe okanye sisongiwe.

I-varnish coating ifumaneka kwi-gloss, satin okanye matt finishes, nokuba ine-tints okanye ayinayo. Ii-varnish zibonelela ngokhuseleko oluphantsi xa kuthelekiswa nezinye ii-coating kunye ne-laminates, kodwa zisetyenziswa kakhulu, ngenxa yexabiso lazo eliphantsi, ukuguquguquka kunye nokulula kokusetyenziswa. Ii-varnish zifakwa njenge-inki, kusetyenziswa enye yeeyunithi ezikwi-press. I-varnish inokugcwala kwi-sheet yonke okanye ibekwe kwindawo efunekayo, ukongeza i-gloss eyongezelelweyo kwiifoto, umzekelo, okanye ukukhusela imvelaphi emnyama. Nangona ii-varnish kufuneka ziphathwe ngononophelo ukuthintela ukukhutshwa kwee-organic compounds eziyingozi emoyeni, xa zomile azinavumba kwaye azinamsebenzi.

Ukwambathisa ngamanzi

I-Aqueous coating inobuhlobo nokusingqongileyo kune-UV coating kuba isekelwe emanzini. Ihlala ixesha elide kune-varnish (ayingeni kwi-press sheet) kwaye ayiqhekeki okanye itshixeke lula. Nangona kunjalo, i-Aqueous ixabisa kabini kune-varnish. Ekubeni isetyenziswa yi-aqueous coating tower ekupheleni kokushicilela, umntu unokubeka i-flood aqueous coating kuphela, kungekhona i-"spot" aqueous coating. I-Aqueous iza ngombala ocwebezelayo, omdaka, kunye ne-satin. Njengee-varnish, i-aqueous coatings ifakwa kumgca kwi-press, kodwa iyakhazimla kwaye ithambile kune-varnish, inokumelana nokukrala okuphezulu kunye nokuguguleka, ayinakwenzeka ukuba ibe tyheli kwaye inobuhlobo nokusingqongileyo. I-aqueous coatings iyoma ngokukhawuleza kunee-varnish, oko kuthetha ukuba ixesha lokutshintsha ngokukhawuleza kwi-press liza.

Iingubo ezifakwe emanzini zifumaneka zikhazimla okanye zicwebezela, zikwabonelela nangezinye iingenelo. Ngenxa yokuba zivala i-inki emoyeni, zinokunceda ekuthinteleni ukuba i-inki zesinyithi zingangcoli. Iingubo ezifakwe emanzini ezenziwe ngokukodwa zingabhalwa ngepensile yesibini, okanye ziprintwe ngaphezulu kusetyenziswa iprinta ye-laser jet, into ephambili ekuqwalaselweni kwiiprojekthi zeposi ezininzi.

Iingubo zamanzi kunye neengubo ze-UV nazo zichaphazeleka lula kukutsha ngamakhemikhali. Kwipesenti encinci kakhulu yeeprojekthi, ngezizathu ezingaqondakaliyo ngokupheleleyo, ezinye imibala ebomvu, eluhlaza okwesibhakabhaka kunye netyheli, efana ne-reflex blue, i-rhodamine violet kunye ne-purple kunye ne-pms warm red, ziyaziwa ngokutshintsha umbala, ukopha okanye ukutsha. Ubushushu, ukuvezwa kukukhanya, kunye nokuhamba kwexesha konke oku kunokubangela ingxaki yale mibala ibalekayo, enokutshintsha nangaliphi na ixesha ukusuka kwangoko emva kokuba umsebenzi ushiye i-press ukuya kwiinyanga okanye kwiminyaka kamva. Imibala ekhanyayo, eyenziwe ngesikrini se-25% okanye ngaphantsi, ichaphazeleka kakhulu kukutsha.

Ukunceda ekulweni nale ngxaki, iinkampani zeinki ngoku zibonelela ngeeinki ezizinzileyo nezitshintshayo ezinombala ofana nowezo zitshayo, kwaye ezi inki zihlala zisetyenziselwa ukuprinta imibala ekhanyayo okanye imibala eqaqambileyo. Nangona kunjalo, ukutsha kusenokwenzeka kwaye kuchaphazele kakhulu inkangeleko yeprojekthi.

Ilaminate

I-Laminate liphepha leplastiki elicwebezelayo okanye eligqunywe ngeplastiki elihlala lisetyenziswa kwiikhava, kwiikhadi zeposi, njl.njl. elikhusela ulwelo nokusetyenziswa kakhulu, kwaye lidla ngokugxininisa umbala okhoyo, linika isiphumo esikhazimlayo. Ii-Laminate ziza ngeentlobo ezimbini: ifilimu kunye nolwelo, kwaye zinokuba nokugqitywa okukhazimlayo okanye oku-matt. Njengoko igama lazo lisitsho, kwelinye icala ifilimu yeplastiki ecacileyo ibekwa phezu kwephepha, kwaye kwelinye icala, ulwelo olucacileyo lusasazwa phezu kwephepha kwaye lome (okanye luphole) njengevanishi. Ii-Laminate zikhusela iphepha emanzini kwaye ke ngoko zilungile kwizinto zokugquma ezifana neemenyu kunye nezigqubuthelo zeencwadi. Ii-Laminate zicotha ukuzifaka kwaye zibiza kakhulu kodwa zibonelela ngomphezulu oqinileyo, onokuhlanjwa. Ziyindlela engcono yokukhusela izigqubuthelo.

Yeyiphi ivarnish efanelekileyo kumsebenzi wakho?

IiLaminate zibonelela ngokhuseleko olukhulu kwaye azinakoyiswa kwiindlela ezahlukeneyo zokusebenza, ukusuka kwiimephu ukuya kwiimenyu, amakhadi eshishini ukuya kwiimagazini. Kodwa ngenxa yobunzima bazo obukhulu, ixesha, ubunzima kunye neendleko, iiLaminate aziqhelekanga kwiiprojekthi ezinee-press runs ezinkulu kakhulu, ixesha elifutshane okanye ixesha elifutshane. Ukuba kusetyenziswa iiLaminate, kunokubakho iindlela ezingaphezu kwesinye zokufezekisa iziphumo ezifunwayo. Ukudibanisa iLaminate nephepha elinzima kuvelisa ukugqitywa okutyebileyo ngexabiso eliphantsi.

Ukuba awukwazi ukwenza isigqibo, khumbula ukuba ezi ntlobo zimbini zokugqiba zingasetyenziswa kunye. Umzekelo, i-spot matte UV coating ingafakwa phezu kwe-gloss laminate. Ukuba iprojekthi iza kugqunywa nge-laminate, qiniseka ukuba ufaka ixesha elongezelelweyo kwaye rhoqo, ubunzima obongezelelweyo xa uthumela ngeposi.

Yintoni umahluko phakathi kwe-UV Varnishing, i-varnishing kunye ne-laminating - iphepha eligqunyiweyo

Nokuba usebenzisa luphi na uhlobo lokwaleka, iziphumo ziya kuhlala zibukeka zingcono ephepheni elifakwe i-coated. Oku kungenxa yokuba umphezulu oqinileyo, ongenamibhobho wesitokhwe ubamba ulwelo okanye ifilimu ephezu kwephepha, ngaphandle kokuyivumela ukuba ingene kumphezulu wesitokhwe esingafakwanga i-coated. Olu phawu lubalaseleyo lunceda ukuqinisekisa ukuba ukugqitywa kokukhusela kuya kuhamba kakuhle. Okukhona umphezulu uthambile, kokukhona umgangatho ungcono.
