Ukuhlaziywa kwezinkinga zohlelo lokusebenza ohlelweni lukayinki olusekelwe emanzini

Oyinki abasuselwe emanzini bahlangabezana nezinkinga ezihlukahlukene ekusebenzeni okungokoqobo, okungase kuhlanganise ukusebenza kukayinki, inqubo yokuphrinta, ukuguquguquka kwe-substrate, nezici zemvelo. Okulandelayo ezinye zezinkinga ezithile: 1. isivinini sokumisa: ijubane lokumisa likayinki osekelwe emanzini ngokuvamile lihamba kancane kunalelo likayinki osuselwe ku-solvent, okungase kuholele enkingeni yokuphrinta, ukuvinjwa noma ukwehlisa ukusebenza kahle kokuphrinta. 2. Ukunamathela: Kwamanye ama-substrates, ukunamathela kweziyinki ezisekelwe emanzini kungase kungabi namandla njengoyinki asekelwe ku-solvent, okungabangela ukuba iphethini ephrintiwe iwe noma iguge kalula. 3. Ukumelana namanzi nokumelana namakhemikhali: Ukumelana kwamanzi nokumelana namakhemikhali kayinki asekelwe emanzini kungase kunganele, okungase kuthinte ukuqina nokuqina kombala wamaphrinti. Ukugqama kombala nokugcwala kwesikhala: Oyinki abasekelwe emanzini bangase bangabi muhle njengabanye oyinki abasuselwa kuncibilikisiwe ngokuya ngokugqama kombala nokugcwala kwendawo, okungase kukhawulele ukusetshenziswa kwabo emikhiqizweni ephrintiwe yekhwalithi ephezulu. Ukunemba kokuphrinta: Uyinki osuselwe emanzini ungandiza uyinki ngesikhathi sokuphrinta ngesivinini esikhulu, okuthinta ukunemba nokucaca kokuphrinta. Ukuzinza kwesitoreji: Ukuzinza kokugcina koyinki okusekelwe emanzini kungase kungabi kuhle njengoyinki asekelwe kuncibilikisiwe. Ukunaka okukhethekile kufanele kukhokhwe ezimeni zokugcina ukuze kugwenywe ukuwohloka kwe-inki. Ukuvumelana nezimo zemvelo: Uyinki osuselwe emanzini uzwela kakhulu kumswakama kanye nezinga lokushisa lendawo ezungezile, futhi izimo zemvelo ezingafaneleki zingase zibe nomthelela ekulevelisweni nomthelela wokuphrinta kayinki. 8. Ukuhambisana kwemishini yokunyathelisa: Ukushintshela kumayinki asekelwe emanzini kungase kudinge ukulungiswa noma ukuguqulwa kwemishini yokunyathelisa ekhona ukuze ivumelane nezici zamayinki asekelwe emanzini. Ukuze kuxazululwe lezi zinkinga, abacwaningi nonjiniyela bayaqhubeka nokuthuthukisa ukwakhiwa kwe-inki esekelwe emanzini, bathuthukise ukusebenza kwayo, kodwa futhi kubuchwepheshe bokunyathelisa kanye nemishini emisha, ukuze bazivumelanise kangcono nezici ze-inki esekelwe emanzini. Ngaphezu kwalokho, ukukhethwa kwama-substrates afanelekile kanye nezindlela zokwelashwa kusengaphambili kuyisihluthulelo sokuqinisekisa imiphumela emihle yokunyathelisa yama-inki asekelwe emanzini.

Ngezansi, ngingathanda ukwabelana ngezinkinga ezintathu ngoyinki nezindlela zokugeza.

Yiziphi izici ezithinta ijubane lokumisa lama-inki asekelwe emanzini?

Yini ebangela ukuthi ama-inki asekelwe emanzini ophe ephepheni?

Ingabe uyinki osuselwe emanzini uzinzile? Indlela yokuvimbela ukujula kombala ongalingani?

Yiziphi izici ezithinta ijubane lokumisa lama-inki asekelwe emanzini?

Ijubane lokumisa likayinki osekelwe emanzini libhekisela esikhathini esidingekayo sokumisa ngemva kokuba uyinki udluliselwe ku-substrate. Uma u-inki oma ngokushesha kakhulu, uyokoma futhi kancane kancane anqwabelene epuletini lokuphrinta ne-anilox roller, futhi angase avimbe i-anilox roller, okuholela ekulahlekeni noma ekubhujisweni kwamachashazi e-halftone nokuvuza okumhlophe khonapho. Ijubane lokumisa uyinki lihamba kancane kakhulu, ekuphrinteni ngemibala eminingi kuzophinde kubangele ukuthi ingemuva libe ngcolile. Kungashiwo ukuthi ijubane lokumisa liwumgomo obalulekile wokwahlulela ikhwalithi yokuphrinta ye-inki esekelwe emanzini. Njengoba isivinini sokumisa sibaluleke kakhulu, yiziphi izici ezithinta ijubane lokumisa likayinki osekelwe emanzini?

Inani elingu-PH, inani le-PH libhekisela ekuphikisweni kwe-alkali kukayinki osuselwe emanzini, okuyisici esibalulekile sokunquma uyinki osuselwe emanzini nokuphrinta. Uma inani elingu-PH likayinki osekelwe emanzini liphezulu kakhulu, i-alkalinity enamandla kakhulu izothinta isivinini sokumisa sikayinki, okuholela endaweni engcolile yangemuva kanye nokungazweli kahle kwamanzi. Uma inani le-PH liphansi kakhulu futhi i-alkalinity ibuthakathaka kakhulu, i-viscosity kayinki izokhuphuka futhi isivinini sokumisa sizoshesha, okuzodala kalula iziphambeko ezinjengokungcola, okuzobangela kalula. Ngaphansi kwezimo ezijwayelekile, kufanele silawule inani le-pH likayinki osuselwe emanzini phakathi kuka-8.0 no-9.5.

2, imvelo yokunyathelisa, ngaphezu kweyinki ngokwayo, indlela esiphrinta ngayo imvelo yangaphandle izophinde ithinte ijubane lokumisa likayinki osekelwe emanzini, njengezinga lokushisa nomswakama weshabhu yokunyathelisa kuthinta isivinini sokumisa inki esekelwe emanzini. , umswakama ohlobene ufinyelela ku-95% Uma kuqhathaniswa no-65%, isikhathi sokumisa cishe sihluke izikhathi ezi-2. Ngesikhathi esifanayo, indawo yokungenisa umoya izophinde ithinte isivinini sokumisa sikayinki osekelwe emanzini. Izinga lokungena komoya lihle, isivinini sokumisa siyashesha, umoya omncane awuhambi kahle, futhi isivinini sokumisa sihamba kancane.

I-substrate, vele, ngaphezu kwalokhu okubili okungenhla, ithintwa inani elingu-PH le-substrate ngokwayo lapho uyinki osuselwe emanzini uphrintwa endaweni engaphansi. Uma iphepha line-acidic, i-ejenti yokuhlanganisa esetshenziswa njengendawo yokomisa kuyinki osekelwe emanzini ayisebenzi, futhi i-alkali ekuyinki osuselwe emanzini iyasuswa ukuze kuthuthukiswe ukomiswa. Uma iphepha line-alkaline, uyinki osekelwe emanzini woma kancane, ngezinye izikhathi ukhawulela uyinki osuselwe emanzini ukuze uzuze ukumelana okuphelele kwamanzi. Ngakho-ke, inani le-pH le-substrate lizophinde lithinte ijubane lokumisa likayinki osekelwe emanzini. Yiqiniso, ngaphezu kwalezi zici ezintathu eziyinhloko ezingenhla, kunezinye izici ezizophinde zithinte ijubane lokumisa lamayinki asekelwe emanzini, njengendlela yokupakisha yama-substrates, njll., lapha ngeke senze isingeniso esiningiliziwe.

Yini ebangela ukuthi ama-inki asekelwe emanzini ophe ephepheni?

Siyini isizathu sokungcoliswa kwe-inki esekelwe emanzini ephepheni? Uma ucubungula inkinga yokungcoliswa kwe-inki esekelwe emanzini, yicabangele kulezi zici ezintathu ezilandelayo:

Kunomehluko omkhulu phakathi kukayinki wokuqala kanye noyinki wokushintsha.

① Uma kuwuyinki woqobo, cabanga ukuthi uphelelwe yisikhathi noma ugcinwe isikhathi eside yini. Zombili lezi zimo zizothinta ukuthungwa kwe-ink pigment. Isixazululo ukunyakazisa i-cartridge ye-inki ekamelweni lokushisa elingaphansi kuka-10 degrees Celsius ukuze i-pigment ihlanganiswe ngokugcwele.

② Uma ubangelwa ukushintsha uyinki, ziningi izizathu. Ngokuvamile kuyinkinga ngesilinganiso samanzi noma i-diluent eyengeziwe phakathi nenqubo yokukhiqiza. Ngokwami ​​asikho isixazululo kulolu daba. Zama ukusebenzisa indlela eshiwo ngenhla kuqala bese uthemba ukuthi ihlukanisa umbala kuphela.

Izinkinga zamaphepha ngokuvamile zihlukaniswa ngamabhokisi ephepha amboziwe kanye nephepha elingagcotshiwe (kufanele lisebenzise iphepha lasendlini, iphepha langaphandle uyinki osuselwe emanzini awukwazi ukulungisa umbala)

① Akukho ongakusho ngephepha elingagcotshiwe. Ngisho noma kuyiphepha elikhulu elimhlophe elingawuthandi u-inki osuselwe emanzini, uma kungelona uhlobo olumboziwe, kuzoba nokufiphala. Isixazululo ukusebenzisa iphepha eliboshwe.

② Iphepha eliboshwe, ukucatshangelwa okuyinhloko ukuthi ngabe iphepha belimanzi, seliphelelwe yisikhathi, ukusetshenziswa kwe-coating kuncane kakhulu okuxubile, kungakhathaliseki ukuthi hlobo luni lwesimo oluzokwenza i-coating yephepha ixubene ayikwazi ukwenza ukuvikelwa kwendawo, phakathi nendawo. umbala oqinile, ukugeleza kwamanzi angaphansi, futhi ekugcineni kubangele ukuqhakaza. Isixazululo kuphela sokulondolozwa kwephepha eligoqayo ukusho ukuthi ibhokisi lokupakisha lephepha lokuqala likathayela kanye nokupakishwa kwepulasitiki ngaphakathi akufanele kuvunyelwe, futhi iphepha elingasetshenzisiwe kufanele libuyiselwe.

Inkinga yezisetshenziswa ezisetshenziswayo. Ikhanda lokuphrinta lithatha isikhathi eside ukuguga, okuholela ekusabalaliseni kukayinki okungalingani kanye nokuqhakaza. Sebenzisa amaqoqo ahlukene noma izinhlobo zikayinki ukuze uhlanganise oyinki nezilinganiso zamakhemikhali ezihlukene ekhanda lokuphrinta. Isofthiwe, isebenzisa umshayeli noma isofthiwe ye-RIP ukuze iphrinte, ayizange ikhethe uhlobo lwephepha oluhambisanayo, okuholele ekutheni ijethi kayinki eningi yeqe umkhawulo wokuthi iphepha lingamunca umswakama, ngaleyo ndlela kubangele ukuqhakaza.

Ingabe uyinki osuselwe emanzini uzinzile? Indlela yokuvimbela ukujula kombala ongalingani?

Oyinki abasuselwe emanzini, owaziwa nangokuthi uyinki ongancibilika emanzini noma ohlakazeka emanzini, bafushaniswa ngokuthi "amanzi noyinki". Oyinki abasuselwe emanzini benziwa ngokuncibilika noma ngokuhlakaza i-resin yamamolekyuli ephezulu encibilika emanzini, ezenza imibala, izithasiselo nezinye izithasiselo ezihlobene nazo ngezinqubo zamakhemikhali nokucubungula ngokomzimba.

Uyinki osuselwe emanzini uqukethe inani elincane lamanzi otshwala njengesixazululi, ukuzinza kweyinki. Ngakho-ke, kufanelekile ikakhulukazi ezimbonini zokupakisha ezifana nokudla nemithi. Uyinki osekelwe emanzini ungahlanzwa ngamanzi, ongashi, angaqhumi, akukho miphumela emibi endaweni yomoya kanye nempilo yabasebenzi, futhi azikho izingozi zomlilo ezibangelwa ugesi omile nezincibilikisi ezivuthayo, ngokuphepha kokukhiqiza.

Uyinki osuselwe emanzini uwuhlobo olusha lukayinki wokuphrinta onombala ophezulu, ongasancibiliki, ucwebezela kahle, ukuphrinta okuqinile, ukuleveli okuhle nokuqukethwe okuqinile okuphezulu. Uyinki osuselwe emanzini kulula ukuwusebenzisa. Lapho unyathelisa, kuphela ngokusho isidingo kusengaphambili ukuze wengeze abantu kampompi amanzi ukuthunyelwa inki omuhle. Enqubweni yokunyathelisa, inani elifanele likayinki omusha lengezwa ngokuqondile, futhi asikho isidingo sokuncibilikisa amanzi okwengeziwe, okungavimbela umbala ukuba uhluke. Uyinki osuselwe emanzini ngokuvamile awusancibiliki emanzini ngemva kokoma. Lapho uqala ukuphrinta, ipuleti lokuphrinta kufanele licwiliswe kuyinki osekelwe emanzini ukuze liqhubeke lizungeza, ngaphandle kwalokho uyinki osuselwe emanzini epuleti lokuphrinta uzokoma ngokushesha, okubangele ukuthi i-roller yepuleti ivinjwe futhi ingakwazi ukuphrinta. Uma kubhekwa intengo ekhuphukayo yezincibilikisi zemvelo okubangelwa ukwanda kokuncipha kwemithombo ye-petroleum, izindleko zokukhiqiza kanye nezindleko zokusebenzisa imvelo zikayinki we-solvent zizokwenyuka usuku nosuku. I-solvent kayinki osuselwe emanzini ikakhulukazi isebenzisa amanzi ampompi, futhi ngenxa yokugcwala okuphezulu kukayinki osuselwe emanzini, ukujula kwepuleti le-gravure kungaba ncane.

Ngakho-ke, ngokombono wezindleko, nakuba oyinki abasekelwe emanzini bebiza, izindleko zabo zokusetshenziswa zizonke zilinganiselwa ukuthi zingaphansi ngo-30% kunoyinki asekelwe ku-solvent. Kukhona futhi nokukhathazeka okuncane mayelana nezinsalela ezinobuthi zezincibilikisi ezindaweni eziphrintiwe. Ukuhlolwa okuyimpumelelo kwesicelo koyinki abasekelwe emanzini ekuphrinteni kwegravure yepulasitiki ngokungangabazeki kulethe izindaba ezinhle ezimbonini zokupakisha eziphrinta imibala.
