Ibhokisi lokudlala lezingane ipotimende lephepha lekhadibhodi elinesibambo
I-iPad Stand elungisekayo, Izibambi Ze-Tablet.
Leli potimende lephepha lisetshenziselwa kakhulu ukugoqa izipho zezingane noma ukuhlela amathoyizi amancane ezingane.Ithoni yayo eyinhloko iluhlaza okwesibhakabhaka nokumhlophe, ukwakheka kwephethini yamachashazi we-wave, ibukeka ihlanzekile, ikhululekile futhi inhle, ifaneleka kakhulu izingane.Futhi ukufanisa umbala okunjalo, angikwazi ukuzibamba kodwa ngifuna ukusebenzisa leli phepha lepotimende lepotimende , ezintweni ezishiwo ngenhla ezithinta ukushintsha kombala wendaba ephrintiwe.
Iphrinta ngesikhathi sokuphrinta nokugcinwa, umbala wayo, ukukhanya, ukugcwala kwawo kuvame ukushintsha, kungakhathaliseki ukuthi uyinki we-monochromatic, noma izinhlobo ezingaphezu kwezimbili zikayinki wombala, ngaphakathi nangaphandle kwesenzo, umbala ungase ube mnyama, futhi ungase ube nokukhanya.Izinga lokuphrinta lekhwalithi enhle kakhulu yileli: iqoqo lemikhiqizo ngaphambi nangemuva kombala omnyama okhanyayo ukuze uhambisane, ube nemibala, ngesikhathi esifanayo ukuze uvumelane nesampula yesigaba sombala omnyama kanye nokukhanya okujulile kukayinki.
Uyinki uyakhanya - amelana nokuguquguquka nokuguquka kombala
Uyinki ekukhanyeni kwelanga, umbala nokukhanya kwawo kuzohluka ngamazinga ahlukahlukene okushintsha, ukumelana nokukhanya okuphelele futhi akushintshi ithoni ye-inki akuyona, ekukhanyeni kwelanga okunamandla, wonke umbala we-inki uzoveza amazinga ahlukene oshintsho.Kunezinhlobo ezimbili zoshintsho.
Ukufiphala: ngaphansi kwesenzo sokukhanya kwelanga imisebe ye-ultraviolet, ukumelana nokukhanya kweyinki kubi, kulahlekelwe umbala ogqamile wangempela, umbala uba mpunga ophaphathekile.Ikakhulukazi uyinki wombala okhanyayo kanye nokuphrinta kwesethi yemibala emine lapho ophuzi nobomvu imibala emibili iphela ngokushesha, futhi i-cyan noyinki iba kancane kancane.
Ukushintshashintsha kombala: ngokungafani nokuphrinta kwe-inki emnyama, ukushintsha kombala ngaphansi kwesenzo sokukhanya kwelanga kumnyama, umbala nawo ushintshile, abantu babiza lolu shintsho ngokushintsha kombala.
Umphumela we-emulsification
Ipuleti yokuphrinta ye-Offsctdruckmasenten ayikwazi ukuhlukaniswa nokumanzisa ingxenye engenalutho yepuleti, i-offscdruckmasenten ingamanzi okuqala kuyinki, amanzi azovela nakanjani into emulsifying.Umbala we-emulsion we-ink uzoncipha, kodwa, ngemva kokuhwamuka kwamanzi kungabuyisela umbala wokuqala, ngakho-ke amanzi amakhulu, inani elikhulu le-emulsion, lizobangela ukuguquguquka.Ikakhulukazi, izinga emulsification of ithoni uyinki ehluke ngokuphelele ndawonye, ukwenzeka ukushintsha kombala ugqame ikakhulukazi.
Izakhiwo zephepha ezibushelelezi zephepha
Ubushelelezi bephepha kanye nekhophi yokuphrinta inobudlelwane obuseduze, hhayi iphepha elibushelelezi ngokuvamile lidinga ingcindezi enkulu, ukuze lenze uyinki futhi inokuxhumana okuhle.Okufana nokunyathelisa inki viscosity, liquidity, silondoloze inani elithile uyinki ifilimu ukushuba, ingcindezi okwandayo ngokuvamile kwenza molecularly imprinted endaweni yokusakaza, ngesikhathi esifanayo, ecwilisa iphepha endaweni, kodwa nokho ukuxhumana abampofu, ezifana: iphepha camera kanye newsprint in ipuleti efanayo ephrintiwe imprinting imiphumela inomehluko omkhulu, ngokusobala ingaqhathanisa umphumela wokuphrinta ohlukile.
Ukumuncwa kwephepha
Iphepha, futhi ubukhulu bomphumela wokumunca kanye nokuphindaphinda kunobudlelwano obuqondile, ngokuvamile kukhwalithi yokunyathelisa yento ephathekayo amashidi ephepha, uma u-inkino we-inkino, i-viscosity ephansi, iphepha lizomunca uxhumano lwe-ink layer eyengeziwe, uma i-stoma yoboya. ububanzi obukhulu kunobubanzi bezinhlayiya ze-pigment, khona-ke, ngisho nezingulube ziphefumula, ukugcwala kokuphrinta kuncipha.Udinga ukwandisa ukujiya kongqimba lukayinki ngendlela efanele.Kodwa-ke, ukwandisa ubukhulu besendlalelo seyinki, ngesikhathi sokufaka i-embossing kuzodala "ukusabalala", kuthinte umphumela wekhophi yokuphrinta.Ukumuncwa kwephepha elincane, kungenza iningi lefilimu ye-inki livele ebusweni bephepha, ukuze ungqimba lweyinki oluphrintiwe lube nokugcwala okuhle.
Paper permeability paper permeability mkhulu, uyokwenza ukushuba uyinki ungqimba mncane, iphepha surface izimbotshana zinkulu, kodwa futhi wenze ingxenye izinhlayiya sombala abangu ngesinyenyela ephepheni ngesikhathi esifanayo, ngakho kukhona umuzwa umbala.Kuze kube sekugcineni, ukusetshenziswa kwendawo emangelengele, ukuthungwa okuxekethile kwephepha, no-inki fluidity nephepha elikhulu, ukunaka umbala.
I-pigment ayimelani nokushisa
Uyinki enqubweni yokumisa, ulula ngokushesha - uyinki yokuphrinta yenjoloba yokomisa ikakhulukazi i-conjunctiva - ukomiswa kwe-oxidation.Ukomiswa kweyinki yokuphrinta ye-offset ngaphambi kokuba kube nesigaba esinqunyiwe, i-ink oxidation polymerization iwukusabela kwe-exothermic, ukomisa ngokushesha kuzokhipha ukushisa okukhulu, uma ukushisa kukhishwa kancane, ngeke kwenze umbala wokushisa wokushisa.Isibonelo: uyinki wombala wegolide uba mnyama futhi ulahlekelwe ukucwebezela kwawo kwasekuqaleni.
Ngesikhathi sokuphrinta, amashidi okunyathelisa anqwabelaniswa abe yizitaki, ngoba embondelene kakhulu, ingxenye ephakathi ye-inki yokunyathelisa ye-polymerization exothermic reaction, ukushisa akulula ukuthumela, izinga lokushisa eliphakeme kakhulu phakathi nendawo yokushintsha umbala. .
Amafutha omile anomphumela wokukhanya
Uyinki wombala ungowethoni epholile, ophuzi okhanyayo, oluhlaza okwesibhakabhaka, oluhlaza okwesibhakabhaka nolunye umbala uyinki, ungasebenzisi uwoyela owomile obomvu, ngoba uwoyela owomile obomvu ngokwawo anombala onsomi ojulile, uzothinta umbala woyinki okhanyayo.
Uwoyela wokoma omhlophe ubonakala umhlophe, kodwa i-conjunctiva inombala onsundu ngokuphaphathekile ngemva kokukhishwa kwe-oxidation.Uma inani lamafutha okoma okumhlophe likhulu kakhulu, ukuphrinta kuzoba nsundu ngokuphuzi uma komile, kuyilapho umbala weyinki emnyama njengoluhlaza, omnyama nonsomi namafutha omile obomvu ngeke uthinteke kakhulu.
Uyinki akakwazi ukumelana ne-alkali
Iphepha lokuphrinta inani le-PH =7, iphepha elingathathi hlangothi lingcono kakhulu, izingulube ezijwayelekile ze-inorganic ezikhiqizwa i-asidi ye-inki, i-alkaline impofu, i-organic pigments acid, i-alkaline ingcono, ikakhulukazi oyinki oluhlaza okwesibhakabhaka, omnyama omnyama uzofiphala nge-alkali.I-alkali medium yellow ngombala kuya obomvu, i-electrochemical aluminium foil stamping, i-India izoba igolide eliphuzi lasendulo ezintweni ezine-alkali, akukho gloss, iphepha le-alkali elibuthakathaka ngaphezulu, elivame ukuhlangana nalo ekunyatheliseni okubopha ngemuva kokukhiqizwa kuqukethe okunamathelayo kwe-alkali, uma ukupakisha ukuphrinta komhlobiso. umkhiqizo uyinto ye-alkaline njengensipho, insipho, impushana yokuwasha nokunye, bonke bafuna ukucabangela ukumelana ne-alkali, ukumelana ne-saponification yokusebenza kweyinki.
Umthelela wendawo yokubeka
Imikhiqizo eminingi yokunyathelisa yokugcina isikhathi eside, izobonisa nakanjani into ephuzi, izizathu zezici eziningana ezilandelayo.
I-Paper fiber iqukethe i-lignin nokushintsha umbala.Amaphephandaba aphrinte ku-newsprint cishe aphenduka abephuzi futhi abe brittle.
Imikhiqizo yokuphrinta yemibala emine yamachashazi ephrinta enemibala emine, iningi ekukhanyeni kwelanga, isimo sezulu, umoya nemvula, ukuguguleka kwezinga lokushisa kwangaphandle, nokunye, ngenxa yokuthi i-pigment ayikwazi ukumelana nokukhanya, ukumelana nokushisa, nombala noma ukufiphala.
Izici zokushintshwa kombala ezintweni eziphrintiwe ziyahlukahluka futhi awukho umkhiqizo ongenza yonke into.Njengaleli potimende lephepha, umbala walo ungashintsha ngokuhamba kwesikhathi.Kodwa okungenani yinhle uma siyisebenzisa.
- Isibambo sensimbi.
- Ihlala isikhathi eside futhi kulula ukuyithwala.
- Ilokhi yensimbi.
- Igweme ukuthi ingavulwa kalula ngenkathi iphethe
- Amandla aphezulu
- Inomthamo omkhulu futhi ingabamba izinto eziningi.
