Oyinki bokuphrinta bayingxenye ebalulekile yenqubo yokunyathelisa futhi badlala indima ebalulekile eqophelweni nasekuqineni kwezinto eziphrintiwe. Kusukela emaphephandabeni kuya emaphaketheni, oyinki abasetshenziswayo bangathinta kakhulu ukubukeka nokusebenza komkhiqizo wokugcina. Kodwa wake wazibuza ukuthi kanjaniuyinki wokunyathelisayenziwe? Lesi sihloko sicubungula inqubo ethokozisayo yokukhiqizwa kukayinki, ihlola izithako, izindlela namasu ahlukene ahilelekile.
Ngaphambi kokuthi singene ohlelweni lokukhiqiza, kubalulekile ukuqonda ukuthi yiniuyinki wokunyathelisakuyinto. Emgogodleni wawo, uyinki wokunyathelisa uwuketshezi noma unamathisele oqukethe ama-pigments noma odayi, izinyibilikisi nezithasiselo. Ndawonye, lezi zingxenye zakha into engasetshenziswa ezindaweni ezihlukahlukene, okuvumela umbhalo nezithombe ukuthi zenziwe kabusha.
Ake sifunde mayelana nezingxenye eziyinhloko zeuyinki wokunyathelisa
Ama-Pigments Nodayi: Lawa ama-colorants akuyinki. Ama-pigment ayizinhlayiya eziqinile ezingancibiliki endaweni ewuketshezi, kuyilapho odayi bencibilika futhi banikeza imibala egqamile. Ukukhetha phakathi kwama-pigments namadayi kuncike ezintweni ezifunwa yiyinki, njengokulula, ukukhanya nokuqina kombala.
Ama-binders: Ama-binders abalulekile ukuze ubambe izinhlayiya ze-pigment ndawonye futhi uqinisekise ukuthi zinamathela ku-substrate (indawo okumele iphrintwe kuyo). Izinamatheliso ezivamile zihlanganisa ama-resin, angatholakala emithonjeni yemvelo noma ahlanganiswe ngamakhemikhali.
I-Solvent: Izincibilikisi ziwuketshezi oluthwala ama-pigments nama-binder. Zingaba ngamanzi, i-solvent-based, noma i-oyela, kuye ngohlobo lukayinki olukhiqizwayo. Ukukhethwa kwe-solvent kuthinta isikhathi sokumisa, i-viscosity kanye nokusebenza kukonke kweyinki.
Izithasiselo: Iqukethe izithasiselo ezahlukahlukene zokuthuthukisa ukusebenza kukayinki. Lokhu kungabandakanya ama-surfactants okuthuthukisa ukugeleza, iziqinisi ukuvimbela ukuhlaliswa, nama-ejenti aqeda amagwebu ukuze anciphise amabhamuza omoya ngesikhathi sokufaka isicelo.
Sicela ubheke inki yokuphrinta yenkampani yethu, imodeliI-LQ-INK I-Web Offset Ink yesethi yokushisa yomshini wamasondo we-web offset
1. Umbala ocacile, ukugxila okuphezulu, ikhwalithi enhle kakhulu yokuphrinta eminingi, ichashazi elicacile, ukukhanya okuphezulu.
2. Ibhalansi ye-inki/yamanzi enhle kakhulu, ukuzinza okuhle ekunyatheliseni
3. Ukuzivumelanisa nezimo okuhle kakhulu, ukumelana okuhle kwe-emulsification, ukuzinza okuhle.
4. Ukumelana nokukhuhla okuhle kakhulu, ukushesha okuhle, ukomisa ngokushesha ephepheni, nokomisa okuphansi ekucindezelweni ukusebenza okuhle kakhulu kokuphrinta ngemibala emine ngesivinini esiphezulu
Inqubo yokukhiqiza uyinki
Ukukhiqizwa koyinki bokuphrinta kubandakanya izinyathelo eziningi, ngasinye sazo esibalulekile ekuqinisekiseni ukuthi umkhiqizo wokugcina uhlangabezana nezindinganiso zomkhakha. Nakhu ukuhlukaniswa kwenqubo evamile yokukhiqiza:
Ukukhetha Izithako
Isinyathelo sokuqala ekwenzeni inki yokunyathelisa ukukhetha izithako ezifanele. Abakhiqizi bakhetha ama-pigments, ama-binder, izincibilikisi nezithasiselo ngokusekelwe ezidingweni ezithile zikayinki, njengombala, isikhathi sokumisa kanye nendlela yokufaka isicelo. Inqubo yokukhetha ngokuvamile ihilela ukuhlola okubanzi nokwakheka ukuze kuzuzwe ukusebenza okufunayo.
Ukuhlakazwa kwe-pigment
Uma izithako sezikhethiwe, isinyathelo esilandelayo ukusabalalisa i-pigment. Lesi isinyathelo esibalulekile sokuqinisekisa ukuthi i-pigment isakazwa ngokulinganayo kuyinki. Ukuhlakazwa kungafinyelelwa kusetshenziswa izindlela ezihlukene, ezihlanganisa izixube zejubane eliphezulu, izigayo zamabhola, noma izigayo zama-roll amathathu. Umgomo uwukwephula izinhlayiya ze-pigment zibe osayizi abacokeme, okuholela ekuqineni kombala okungcono nokuvumelana.
Hlanganisa
Ngemuva kokuthi ama-pigments ahlakazekile, isinyathelo esilandelayo ukuwaxuba nama-binders nama-solvents. Lokhu kwenziwa endaweni elawulwayo ukuze kuqinisekiswe ukuthi uyinki ufinyelela i-viscosity oyifunayo kanye nezici zokugeleza. Inqubo yokuxuba ingathatha amahora ambalwa, kuye ngokuthi iresiphi nemishini esetshenzisiwe.
Ukuhlola Nokulawula Ikhwalithi
Ukulawulwa kwekhwalithi kuyisici esibalulekile sokwenziwa kweyinki. Amasampula kayinki athathwa ezigabeni ezihlukahlukene zokukhiqiza futhi ahlolwe ukunemba kombala, i-viscosity, isikhathi sokumisa kanye nezakhiwo zokunamathela. Lokhu kuqinisekisa ukuthi uyinki uhlangabezana nokucaciswa okudingekayo futhi usebenza kahle ezinhlelweni zokuphrinta.
Ukupakisha
Uma uyinki usuphumelele zonke izivivinyo zokulawula ikhwalithi, uyapakishwa ukuze usatshalaliswe. Oyinki bokuphrinta bavame ukugcinwa ezitsheni ezingangeni ukukhanya nezingangeni emoyeni, ezinganciphisa ikhwalithi yazo. Ukupakishwa okufanele kubalulekile ekugcineni ukusebenza kukayinki ngesikhathi sokugcinwa nokuthunyelwa.
Uhlobo lukayinki wokuphrinta
Kunezinhlobo eziningi zoyinki wokuphrinta, ngayinye yakhelwe uhlelo oluthile. Ezinye zezinhlobo ezivame kakhulu zihlanganisa:
Uyinki we-Offset:Isetshenziswa ekunyatheliseni kwe-offset, lo inki waziwa ngesikhathi sawo sokoma ngokushesha kanye nokuzala kabusha kombala okuhle kakhulu.
I-Flexographic Inks:Oyinki be-Flexographic bavame ukusetshenziswa emaphaketheni futhi benzelwe ukuphrinta ngesivinini esikhulu kuma-substrates ahlukahlukene.
I-Gravure Ink:Lolu hlobo lukayinki lusetshenziswa ekuphrinteni i-gravure futhi lwaziwa ngekhono lalo lokukhiqiza izithombe ezisezingeni eliphezulu ezinemininingwane emihle.
Uyinki Wedijithali:Ngokukhula kokuphrinta kwedijithali, oyinki bathuthukiswe ngokukhethekile ukuze basetshenziswe kumaphrinta we-inkjet nama-laser.
Ngamafuphi, ukwenziwa koyinki bokunyathelisa kuyinqubo eyinkimbinkimbi neyinkimbinkimbi ehilela izithako ezikhethwe ngokucophelela, amasu okukhiqiza anembile kanye nokulawulwa kwekhwalithi okuqinile. Ukuqonda ukuthi u-inki wokunyathelisa wenziwa kanjani akugcini nje ngokugqamisa isayensi ngemuva kwalo mkhiqizo obalulekile, kodwa futhi kugcizelela ukubaluleka kwawo embonini yokunyathelisa. Kungakhathaliseki ukuthi okokuthengisa noma ubuciko, ikhwalithi ye-inki yokunyathelisa ithinta kakhulu ukukhishwa kokugcina, okuyenza ibe yingxenye ebalulekile yomhlaba wokunyathelisa. Njengoba ubuchwepheshe buqhubeka nokuvela, kuzoba kanjalo nezindlela nezinto zokwakha ezisetshenziswa ekukhiqizeni uyinki, okuvula indlela yezixazululo zokuphrinta ezintsha esikhathini esizayo.
