Iprintwa njani ilogo kwiindebeZingaphi iindlela? Okwangoku, indlela yokuprinta ilogo kunye nepateni kwikomityi ixhomekeke kwimeko ethile.
Oku kulandelayo kuchaza inkqubo yokuprinta iikomityi zesikrini esiphambili kwimarike:
Ukuprinta isikrini kukwandisa ilaphu lesilika, ilaphu lefayibha yokwenziwa okanye i-mesh yesinyithi kwisakhelo sesikrini, nokwenza ipleyiti yokuprinta isikrini ngokukrola ngesandla ifilimu yepeyinti okanye ukwenza ipleyiti ye-photochemical. Itekhnoloji yokuprinta isikrini yanamhlanje isebenzisa izixhobo ezibuthathaka ukwenza iipleyiti zokuprinta isikrini ngokwenza iipleyiti zefoto.
Indlela yokwenza iipleyiti:
Indlela yokwenza ipleyiti ngqo kukuqala ubeke isiseko sefilimu yesandla esigqunywe ngezinto ezithambileyo kwitafile yokusebenza kunye nefilimu ethambileyo ijonge phezulu, ubeke isakhelo semesh yesandla esoluliweyo sithe tyaba kwisiseko sefilimu, uze ubeke i-slurry ethambileyo kwisakhelo semesh uze usifake phantsi koxinzelelo nge-scraper ethambileyo, ususe isiseko sefilimu yeplastiki emva kokuba yomile ngokwaneleyo, uze uncamathisele i-mesh yesandla sefilimu ethambileyo kuyo ukuze iprintwe kwipleyiti, enokusetyenziswa emva kophuhliso. Emva kokomisa, kwenziwa ukuprintwa kwesikrini sesilika.
Ukuhamba kwenkqubo:
yoluliwe iNet – ukususa amafutha – ukomisa – ukususa isiseko sefilimu – ukuvezwa – Uphuhliso – ukomisa – Uhlaziyo – ukuvalwa kwesikrini
umgaqo wokusebenza:
Ukuprinta kwesikrini kuqulathe izinto ezintlanu: ipleyiti yokuprinta isikrini, i-scraper yokukrala, i-inki, itafile yokuprinta kunye ne-substrate.
Umgaqo osisiseko wokuprinta isikrini kukusebenzisa umgaqo osisiseko wokuba i-mesh yenxalenye yemizobo yepleyiti yokuprinta isikrini ingena kwi-inki kwaye i-mesh yenxalenye engeyiyo imizobo ingena kwi-inki.
Xa uprinta, galela i-inki kwelinye icala lepleyiti yokuprinta isikrini, ufake uxinzelelo oluthile kwinxalenye ye-inki yepleyiti yokuprinta isikrini nge-scraping scraper, uze uye kwelinye icala lepleyiti yokuprinta isikrini ngaxeshanye. I-inki icinezelwa ukusuka kwi-mesh yenxalenye yegraphic ukuya kwi-substrate yi-scraper ngexesha lokuhamba. Ngenxa ye-viscosity ye-inki, uphawu luqiniswa ngaphakathi koluhlu oluthile. Ngexesha lenkqubo yokuprinta, i-scraper ihlala inxibelelana nepleyiti yokuprinta isikrini kunye ne-substrate, kwaye umgca woqhagamshelwano uhamba ngokuhamba kwe-scraper. Ngenxa yomsantsa othile phakathi kwepleyiti yokuprinta isikrini kunye ne-substrate, ipleyiti yokuprinta isikrini ivelisa amandla okusabela kwi-scraper ngokusebenzisa uxinzelelo lwayo, Le mpendulo ibizwa ngokuba yi-resilient. Ngenxa yendima yokuqina, ipleyiti yokuprinta isikrini kunye ne-substrate zikwi-mobile line contact kuphela, ngelixa ezinye iindawo zepleyiti yokuprinta isikrini zahlulwe kwi-substrate. Yenza i-inki kunye nesikrini ziqhekeke, qinisekisa ukuchaneka kobukhulu bokuprinta kwaye uphephe ukukhuhla i-substrate. Xa i-scraper ikrwela yonke indlela ebhalwe ngayo, iyaphakama, kwaye nepleyiti yokuprinta isikrini nayo iyaphakama, ize ikrwele i-inki kancinci ibuyele kwindawo yayo yokuqala. Olu luhambo lokuprinta.
Iingenelo zokuprinta isikrini:
(1) Akuthintelwanga bubungakanani kunye nokuma kwesiseko
Ukuprinta kwesikrini akukwazi ukuprinta kuphela kwindawo esezantsi, kodwa kukwanokuprinta kwinto emile okwesimo esikhethekileyo, njengomphezulu ongqukuva. Nantoni na enesimo inokuprintwa ngokuprinta kwesikrini. Ukuprinta kwesikrini kwiikomityi kuqheleke kakhulu.
(2) Uyilo luthambile kwaye uxinzelelo lokuprinta luncinci
Isikrini sithambile kwaye siyanwebeka.
(3) Ugqunywe ngongqimba lweyinki oluqinileyo
Ingaprintwa ngombala omhlophe qwa kwiphepha elimnyama liphela, ngengqiqo enamandla enamacala amathathu.
(4) Ifanelekile kwiintlobo ngeentlobo zee-inki
(5) Ukumelana okunamandla kokujikeleza okubonakalayo
Ingagcina ukukhanya kwezinto eziprintiweyo kungatshintshi. (ubushushu kunye nokukhanya kwelanga akunampembelelo). Oku kwenza ukuprinta kube yinto yokuzincamathelisa ngaphandle kokongeza uboya kunye nezinye iinkqubo.
(6) Iindlela zokuprinta eziguquguqukayo nezihlukeneyo
(7) Ukwenza iipleyiti kulula, ixabiso liphantsi kwaye iteknoloji kulula ukuyiqonda
(8) Ukunamathela okuqinileyo
(9) Inokuba kukuprinta isikrini sesilika ngesandla okanye ukuprinta ngomatshini
(10) Ifanelekile ukuboniswa ixesha elide, kwaye iintengiso ezingaphandle zicacile
Ingqiqo enamandla enamacala amathathu:
Ngobume obutyebileyo, ubukhulu beleya ye-inki yokuprinta kunye nokuhombisa nge-offset buyi-5 microns, ukuprinta nge-gravure kumalunga ne-12 microns, ubukhulu beleya ye-inki yokuprinta nge-flexographic (aniline) yi-10 microns, kwaye ubukhulu beleya ye-inki yokuprinta kwesikrini budlula kakhulu ubukhulu beleya ye-inki engentla, ngokubanzi ukuya kuthi ga kwi-30 microns. Ukuprinta kwesikrini esityebileyo kwibhodi yesekethe ekhethekileyo eprintiweyo, enobukhulu beleya ye-inki ukuya kuthi ga kwi-1000 microns. I-Braille yeBraille iprintwa nge-inki efumileyo, kwaye ubukhulu beleya ye-inki efumileyo bunokufikelela kwi-1300 microns. Ukuprinta kwesikrini kunomaleya we-inki otyebileyo, umgangatho wokuprinta otyebileyo kunye nengqiqo enamandla enemilinganiselo emithathu, engenakuthelekiswa nezinye iindlela zokuprinta. Ukuprinta kwesikrini akunakushicilela kuphela i-monochrome, kodwa nokuprinta nge-chromatic kunye nokuprinta umbala wesikrini.
Ukumelana nokukhanya okunamandla:
Ngenxa yokuba ukuprinta kwesikrini kuneempawu zokungaprinti, kunokusebenzisa zonke iintlobo zee-inki kunye neengubo, kungekuphela nje i-slurry, i-adhesive kunye nee-pigment ezahlukeneyo, kodwa kunye nee-pigment ezinamaqhekeza arhabaxa. Ukongeza, i-inki yokuprinta isikrini kulula ukuyisebenzisa, umzekelo, i-pigment engangenisi ukukhanya inokubekwa ngqo kwi-inki, enye into enokuprintwa kwesikrini. Iimveliso zokuprinta isikrini zinezibonelelo ezinkulu zokuxhathisa ukukhanya okunamandla. Lo mkhuba ubonisa ukuba ngokwenqanaba eliphezulu loxinano olulinganisiweyo emva kokuprinta iphepha eligqunywe nge-inki emnyama, ukuprinta kwe-offset yi-1.4, ukuprinta kwe-convex yi-1.6 kunye nokuprinta kwe-gravure yi-1.8, ngelixa uluhlu oluphezulu loxinano lokuprinta kwesikrini lunokufikelela kwi-2.0. Ke ngoko, ukumelana kokukhanya kweemveliso zokuprinta isikrini kunamandla kunokwezinye iintlobo zeemveliso zokuprinta, ezifaneleke ngakumbi kwintengiso yangaphandle kunye neempawu.
Indawo enkulu yokuprinta:
Ubungakanani bendawo obuphezulu obuprintiweyo ngokuprinta okuqhelekileyo, ukubumba kunye nezinye iindlela zokuprinta bubungakanani bephepha elipheleleyo. Ukuba lidlula ubungakanani bephepha elipheleleyo, linqunyelwe zizixhobo zoomatshini. Ukuprinta kwesikrini kungasetyenziselwa ukuprinta kwindawo enkulu. Namhlanje, uluhlu oluphezulu lweemveliso zokuprinta kwesikrini lunokufikelela kwiimitha ezi-3 × iimitha ezi-4 nangaphezulu.
Ezi ngongoma zine zingentla ngumahluko phakathi kokuprintwa kwesikrini kunye nokunye ukuprintwa, kunye neempawu kunye neenzuzo zokuprintwa kwesikrini. Ukuqonda iimpawu zokuprintwa kwesikrini, ekukhetheni iindlela zokuprinta, sinokuphuhlisa amandla kwaye siphephe ubuthathaka, sigxininise iingenelo zokuprintwa kwesikrini, ukuze sifumane isiphumo sokuprinta esifanelekileyo.
Ukugquma kwe-UV:
Ukugquma kwe-UV yendawo kubhekisa ekuprintweni kwesikrini sesilika sephethini kushicilelo olumnyama lokuqala nge-UV varnish. Emva kokusebenzisa i-UV varnish, xa kuthelekiswa nesiphumo sokuprinta esijikelezileyo, iphethini yokupholisha ibonakala ikhanya, ikhanya kwaye inamacala amathathu. Ngenxa yokuba umaleko we-inki yokuprinta isikrini sesilika utyebile, uya kukhukhumala emva kokuphola kwaye ubonakale ngathi yi-indentation. Ukugquma kwe-UV kwesikrini sesilika kunamandla kune-UV engaphantsi ngokuphakama, ukuguda kunye nobukhulu, ngoko ke ibisoloko ithandwa ngabarhwebi bamanye amazwe.
I-UV glazing yendawo yokuprinta isikrini sesilika isombulule ingxaki yokunamathela kwifilimu iBop okanye ipetpopp emva kokuprinta okumnyama, kwaye inokuba yi-convex. Ayikwazi ukukrwela, ayikwazi ukugoba kwaye ayinavumba liphantsi. Oku kudala indawo enkulu yemarike, engasetyenziswa kwiindawo zokuprinta ezifana neekomityi, iimpawu zorhwebo, iincwadi, intengiso njalo njalo.
Iingenelo ezinkulu kushishino lwendebe
Ezona nzuzo zinkulu kushishino lweekomityi zezi: ukwenza iipleyiti okulula nokungabizi kakhulu, iindleko eziphantsi zokuprinta enye, kwaye ipateni eprintiweyo inemvakalelo yemilinganiselo emithathu. Isebenza kwiindidi ezahlukeneyo zeekomityi. Ingaprintwa kwiiikomityi zentsimbi engagqwaliyo, iibhotile zemidlalo ze-aluminium, indebe yeplastikis, iibhotile zemidlalo, iikomityi ze-thermos, iikomityi zekofu, iikomityi zebhiya, iikomityi zemoto, iflaski yesinqe, iikomityi zeseramikhi, i-barwarekwayeizipho ezahlukeneyoUkuba ufuna ukuprinta kwikomityi, ncedaQhagamshelana nathikwaye siza kuyila eyona nkqubo ilungileyo kuwe
