Ukupakisha ulawulo lomgangatho wezinto | I-13 yokungaphumeleli komgangatho oqhelekileyo kwinkqubo yokudlulisa i-thermal, bangaphi obonileyo?

Itekhnoloji yokudlulisa i-Thermal ibhekisa kwindlela yoshicilelo esebenzisa iphepha lokudlulisa eliqatywe ngee-pigments okanye iidayi njengento ephakathi ukudlulisa ipateni yomaleko we-inki kwindawo ephakathi ukuya kwi-substrate ngokufudumeza, ukucinezela, njl njl. qhagamshelana nendawo eqatywe nge-inki kunye ne-substrate. Ngokufudumeza kunye noxinzelelo lwentloko yoshicilelo lwe-thermal kunye ne-roller ye-impression, i-inki kwi-medium iya kunyibilika kwaye idlulisele kwi-substrate ukufumana imveliso eprintiweyo efunekayo.

1. Iphepha elipheleleyo lepleyiti yeentyatyambo
I-Phenomenon: amabala kunye neepateni zivela kwiphepha elipheleleyo.

Isizathu: I-viscosity ye-inki iphantsi kakhulu, i-angle ye-scraper ayifanelekanga, ukushisa kokumisa kweyinki akwanelanga, umbane we-static, njl.

Ukuxazulula iingxaki: Ukwandisa i-viscosity, lungisa i-angle ye-scraper, ukwandisa ukushisa kwe-oven, kunye nokugqoka kwangaphambili ngasemva kwefilimu nge-agent static.

2. Ukutsala

I-Phenomenon: Imigca efana ne-comet iya kubonakala kwelinye icala lepateni, isoloko ibonakala kwi-inki emhlophe kunye nomda wepatheni.

Isizathu: I-ink pigment particles inkulu, i-inkino ayicocekanga, i-viscosity iphezulu, umbane we-static, njl.

Ukuxazulula iingxaki: Hlunga i-inki kwaye ususe i-scraper ukunciphisa ukuxininisa; i-inki emhlophe inokulolwa kwangaphambili, ifilimu inokunyangwa ngombane ongatshintshiyo, kunye ne-scraper kunye nepleyiti inokukhutshelwa ngentonga ebukhali, okanye i-agent e-static inokongezwa.

3. Ukubhaliswa kombala okungalunganga kunye nezantsi eliveziweyo

I-Phnomenon: Xa imibala emininzi ibekwe ngaphezulu, ukutenxa kweqela lombala kwenzeka, ngakumbi kumbala ongasemva.

Izizathu eziphambili: Umatshini ngokwawo unokuchaneka kakubi kunye nokuguquguquka; ukwenza iipleyiti kakubi; ukwandiswa okungafanelekanga kunye nokucutheka kombala ongasemva.

Ukusombulula ingxaki: Sebenzisa izibane zestrobe ukubhalisa ngesandla; ukwenza ipleyiti kwakhona; ukwandisa kunye nenkontileka phantsi kwempembelelo yempembelelo ebonakalayo yepateni okanye musa ukwenza mhlophe inxalenye encinci yepateni.

4. I-inki ayikrwelwanga ngokucacileyo

Isenzeko: Ifilim eprintiweyo ibonakala inkungu.

Isizathu: Isakhelo sokulungisa i-scraper sikhululekile; umphezulu wepleyiti awucocekanga.

Ukulungisa ingxaki: Lungiselela isikrabhu kwaye ulungise isibambi seblade; coca ipleyiti yokushicilela, kwaye usebenzise umgubo wokucoca xa kukho imfuneko; faka ukuhanjiswa komoya okubuyela umva phakathi kwepleyiti kunye ne-scraper.

5. Iiflake zombala

I-Phenomenon: Umbala uyagqabhuka kwiindawo zengingqi zeepateni ezinkulu, ngakumbi kwiifilim eziphathwe kwangaphambili zeglasi eprintiweyo kunye nentsimbi engatyiwayo.

Isizathu: Umaleko wombala unokugqabhuka ngakumbi xa uprintwa kwifilimu ephathwayo; umbane ongatshintshiyo; umaleko we-inki wombala ungqindilili kwaye awomiswanga ngokwaneleyo.

Ukusombulula ingxaki: Yandisa ubushushu be-oveni kwaye unciphise isantya.

6. Ukukhawuleza kokudlulisa okungalunganga

I-Phenomenon: Umaleko wombala odluliselwe kwi-substrate utsalwa ngokulula ngeteyiphu yovavanyo.

Isizathu: Ukwahlula okungafanelekanga okanye iglue yangasemva, ngokukodwa ibonakaliswe yiglue yangasemva engahambelani ne-substrate.

Ukuxazulula ingxaki: Faka indawo yeglue yokwahlula (lungisa ukuba kuyimfuneko); buyisela iglu yangasemva ehambelana ne-substrate.

7. Ukuchasa ukuncamathela

I-Phenomenon: Umaleko we-inki uyagqabhuka ngexesha lokubuyela umva, kwaye isandi siphezulu.

Unobangela: Ukuxinezeleka okuninzi okujikajikayo, ukomiswa okungaphelelanga kwe-inki, ileyibhile engqindilili kakhulu ngexesha lokuhlolwa, ubushushu obuphantsi bendlu kunye nokufuma, umbane ongatshintshiyo, isantya esikhawulezayo sokushicilela, njl.

Ukusombulula ingxaki: Nciphisa ukuxinana kwama-winding, okanye unciphise ngokufanelekileyo isantya soshicilelo, wenze ukomisa kugqibelele, ulawule ubushushu obungaphakathi kunye nokufuma, kunye nokufaka i-agent emileyo kwangaphambili.

8. Ukulahla amachaphaza

Isenzeko: Amachaphaza avuzayo angaqhelekanga avela kumnatha ongekho nzulu (afana namachaphaza angenako ukuprintwa).

Unobangela: I-inki ayinakufakwa.

Ukucombulula ingxaki: Coca i-layout, sebenzisa i-electrostatic ink suction roller, ugxininise amachaphaza, ulungelelanise uxinzelelo lwe-scraper, kwaye unciphise ngokufanelekileyo i-viscosity ye-inki ngaphandle kokuchaphazela ezinye iimeko.

9. Amaqhuqhuva afana namaxolo e-orenji avela xa igolide, isilivere, kunye neperilescent ziprintwa

I-Phenomenon: Igolide, isilivere, kunye ne-pearlescent zihlala zine-orenji-ezifana ne-ripples kwindawo enkulu.

Unobangela: Amasuntswana egolide, isilivere, kunye neperilescent makhulu kwaye awakwazi ukusasazwa ngokulinganayo kwitreyi ye-inki, okukhokelela ekuxineni okungalinganiyo.

Ukusombulula ingxaki: Phambi kokushicilela, xuba i-inki ngokulungeleleneyo, umpompe i-inki kwitreyi ye-inki, kwaye ubeke isivutheli-moya seplastiki kwitreyi ye-inki; ukunciphisa isantya soshicilelo.

10. Ukuveliswa kakubi kweeleya eziprintiweyo

Isenzeko: Iipateni ezineenguqu ezinkulu kakhulu kumaleko (ezinje nge-15% -100%) zihlala zisilela ukuprinta kwindawo yethoni ekhanyayo, zinengxinano enganelanga kwindawo yethowuni emnyama, okanye ekudibaneni kwethoni ephakathi nendawo ecacileyo. ukukhanya kunye nobumnyama.

Isizathu: Uluhlu lwenguqu lwamachaphaza lukhulu kakhulu, kwaye i-inki ayinamatheli kakuhle kwifilimu.

Ukusombulula ingxaki: Sebenzisa irola yokufunxa inki ye-electrostatic; yahlula ngamacwecwe amabini.

11. Iglosi yokukhanya kwiimveliso eziprintiweyo

I-Phenomenon: Umbala wemveliso eprintiweyo ukhaphukhaphu kunesampulu, ngakumbi xa uprinta isilivere.

Unobangela: I-viscosity ye-inki iphantsi kakhulu.

Ukuxazulula ingxaki: Yongeza i-inki yokuqala ukwandisa i-viscosity ye-inki kwisixa esifanelekileyo.

12. Iincam zoonobumba abamhlophe zijijekile

I-Phenomenon: Imida ejijekileyo ikholisa ukuvela kwincam zoonobumba abaneemfuno zobumhlophe obuphezulu.

Isizathu: I-granularity kunye ne-pigment ye-inki ayilungile ngokwaneleyo; i-viscosity ye-inki iphantsi, njl.

Ukuphelisa: ukulola imela okanye ukongeza izongezo; ukulungisa i-angle ye-scraper; ukwandisa i-viscosity ye-inki; ukutshintsha ipleyiti yokukrola yombane kwipleyiti yelaser.

13. Ukugquma okungalinganiyo kwefilimu efakwe ngaphambili yensimbi engenasici (i-silicone yokugqoka)

Ngaphambi kokushicilela ifilimu yokudlulisa yensimbi engenasici, ifilimu idla ngokuphathwa kwangaphambili (i-silicone coating) ukuxazulula ingxaki yokungagqibekanga kwe-peeling ye-inki layer ngexesha lokudluliselwa (xa izinga lokushisa lingaphezulu kwe-145 ° C, kunzima ukukhupha. umaleko we-inki kwifilimu).

I-Phenomenon: Kukho imigca kunye nemicu kwifilimu.

Isizathu: Ukushisa okunganeleyo (ukubola okungonelanga kwe-silicon), umlinganiselo ongafanelekanga we-solvent.

Ukuphelisa: Yandisa iqondo lobushushu le-oven ukuya kumphakamo osisigxina.
