Izici namakhono wokuphrinta we-ink esekelwe emanzini ephepheni elihlanganisiweibhokisi le-chocolate
I-ink esekelwe emanzini ingumkhiqizo we-inki wemvelo othole ukunakwa okubanzi eminyakeni yamuva njeibhokisi le-khekhe. Uyini umehluko phakathi kwe-inki esuselwa emanzini kanye ne-inki evamile yokuphrinta, futhi yini amaphuzu adinga ukunakwa kusetshenziswe? Lapha, i-meibang izoyichaza ngokuningiliziwe ngawe.
Uyinki osuselwa emanzini usetshenzisiwe ekushicilelweni kwephepha elihlanganisiwe isikhathi eside phesheya kanye neminyaka engaphezu kwengu-20 ekhaya. Ukuphrinta kwamaphepha okukhohlakele sekuye kwathuthuka kusuka ekuphrintweni okuholayo (ukuphrinta kosizo), ukuphrinta kosizo), ukuphrinta kwe-offset (ukuphrinta kwe-offset) kanye nokuphrinta kwamanzi okugeza okuthengiswayo kwanamuhla. Uyinki osuselwa emanzini aguqukayo ubuye wakhula kusuka ku-rosin-monoc acid eguquliwe uchungechunge lwe-resin (ibanga eliphansi) ku-acrylic resin uchungechunge (ibanga eliphakeme). Ipuleti lokuphrinta libuye lidluliselwe epuletini lerabha ukuze lihlele ipuleti. Umshini wokuphrinta usethuthuke kancane kancane kusuka emishini emibalabala emibala emibili noma emibili enama-roller amakhulu kuya kuma-flexis anemibala emithathu noma emigqeni emine.
Ukwakheka kanye nezici zama-inks asuselwa emanzini kuyafana nalokho kwe-inks yokuphrinta ejwayelekile. Ama-inks asuselwa emanzini ajwayele ukwakhiwa ngamabala, ama-linders, ama-auxiliaiya nezinye izinto. Ama-Colorants angamabala e-ink esuselwa emanzini, enikeza i-ink umbala othile. Ukuze wenze umbono uqhakaze ngokuphrinta okuguquguqukayo, amabala asobala asebenzisa imibala ngokuqina okuhle kwamakhemikhali kanye namandla aphezulu okufaka imibala; Isigaxa siqukethe amanzi, ama-resin, amakhompiyutha aphine namanye ama-solvents ezi-organic. I-Resin iyingxenye ebaluleke kakhulu kuma-inks asekwe emanzini. I-acrylic ye-acrylic acrylic ivame ukusetshenziswa. Ingxenye ye-Binder ithinta ngqo umsebenzi wokunamathela, isivinini sokomisa, ukusebenza okunamathela, njll. Amakhompiyutha we-Amine agcina ikakhulu inani le-ink ye-ink ye-alkaline esuselwa emanzini, ukuze i-acrylic resin inganikeza umphumela ongcono wokuphrinta. Amanzi noma amanye ama-solvents ezi-organic ikakhulukazi ancibilika ama-resins, alungise ukubonwa kanye nesivinini sokomisa uyinki; Ama-ejenti asizayo ikakhulukazi afake phakathi: Defouamer, blocker, stabilizer, diliunt, njll.
Njengoba i-ink esekelwe emanzini ingukwakheka kwensipho, kulula ukukhiqiza ama-bubble ekusetshenzisweni, ngakho-ke i-silicone oyela kufanele ingezwe njenge-defouamer yokuvimbela futhi isuse ukusebenza kwe-ink. Ama-blockers asetshenziselwa ukuvimbela ijubane lokomisa we-ink esekelwe emanzini, avikele i-ink ukuthi isomiswe kwi-anilox roll futhi yehlise unamathisela. I-Stabilizer ingaguqula inani le-PH ye-inki, futhi libuye lisetshenziswe njengelingcolile lokunciphisa i-viscosity ye-ink. I-dilount isetshenziselwa ukunciphisa umbala we-inki osuselwa emanzini, futhi futhi ingasetshenziswa njengesiqu sokwenza ngcono ukugqama kwe-ink-esekwe emanzini. Ngaphezu kwalokho, ezinye i-wax kufanele zengezwe ku-inki esekelwe emanzini ukukhulisa ukumelana kwayo.
I-ink esekelwe emanzini ingahlanganiswa namanzi ngaphambi kokoma. Lapho uyinki womile, ngeke isancibilika emanzini noyinki. Ngakho-ke, inkinki esekwe emanzini kumele ivuswe ngokugcwele ngaphambi kokusebenzisa ukugcina umfaniswano wokwakheka kwe-inki. Lapho ungeza uyinki, uma uyinki yensalela ethangini le-INK iqukethe ukungcola, kufanele kuhlungwa kuqala, bese kusetshenziswa ngoyinki omusha. Lapho unyathelisa, ungavumeli inki eyomile e-anilox roll ukugwema ukuvimba umgodi we-inking. Ukuvimba ukuhanjiswa kwe-ink ye-ink kubangela ukungaziphathi. Ngesikhathi senqubo yokuphrinta, i-flexplate kufanele ihlale isongwe yi-ink ukugwema ukuvimba iphethini yombhalo epuletini lokuphrinta ngemuva kokomile. Ngaphezu kwalokho, kutholakala ukuthi lapho i-ik ye-ink esuselwa emanzini iphakeme kancane, akufanelekile ukwengeza amanzi ngokugwema ukuqina kokuqina kwe-ink. Ungangeza inani elifanele le-stabilizelizer ukuze uzilungiselele.
