Nekushandiswa kwezvinhu zvisingabatike zvekudhindisa zvakaita segoridhe nesirivheri kadhibhodhi uye bepa rekufambisa relaser mumapakeji efodya, tekinoroji yekudhinda yeUV offset iri kuwedzera kushandiswa zvakanyanya mukudhinda pasuru yefodya.Nekudaro, kutonga kweUV offset kudhinda maitiro kwakaomawo, uye matambudziko mazhinji emhando ari nyore kuitika mukugadzira.
Ink roller glaze
Mukuita kweUV offset kudhinda, kupenya kupenya kunoitika kana inki roller ichimhanya zvakanyanya kwenguva yakareba, zvichikonzera inki isina kunaka, uye kuenzana kweinki nemvura kunonetsa kuvimbiswa.
Inowanikwa mukugadzirwa chaiko kuti batch yeinki mitsva haiburitse glaze mumwedzi wekutanga wekushandiswa, saka kunyudza iyo inki roller muinki roller inoderedza paste kwemaawa mana kusvika mashanu mwedzi wega wega unogona kudzoreredza kushanda kweinki. iyo inki rollers, nokudaro kuderedza chizvarwa che glossy glaze ye inki rollers.
Ink roller kuwedzera
Sezvatinoziva tese, UV inki inoparadza zvakanyanya, saka inki roller yakakomberedzwa neUV offset inki ichawedzerawo.
Apo inki roller inowedzera, matanho akakodzera ekurapa anofanira kutorwa munguva kuti arege kudzivirira migumisiro yakaipa.Chinhu chinonyanya kukosha ndechekudzivirira kuwedzera kubva pakukonzera kudzvinyirira kwakanyanya pane inki roller, zvikasadaro zvinokonzeresa mabhubhu, kuputsika kwegel uye zvimwe zviitiko, uye kunyange kukonzera kukuvara kunouraya kune UV offset kudhinda michina mumatambudziko akakomba.
Kudhinda kwenhema
Iko kusarongeka kwekudhinda muUV offset kudhinda mapaketi efodya kunogona kukamurwa kuita mhando mbiri dzinotevera.
(1) UV yekurapa mavara dhizaini kudhinda hakuna kusimba.
Muchiitiko ichi, kutevedzana kwemavara kunofanirwa kurongeka zvine musoro, uye mwenje weUV pakati pemadhishi emavara unofanirwa kudzivirirwa kusvika pazvinobvira.Kazhinji, iyo chena inki layer yekutanga kudhindwa yakakora uye UV kurapwa kunoitwa;Paunenge uchidhinda ingi chena kechipiri, iyo inki layer ichave yakatetepa pasina UV kurapwa.Mushure mekudhindisa nemamwe madhiketi emavara, iyo flat effect inogonawo kuwanikwa.
(2) Nzvimbo huru yokudhinda mundima haisi yechokwadi.
Pane zvinhu zvakawanda zvinokanganisa nzvimbo huru yekudhinda ndima.Kuti udzivise nzvimbo huru yekudhinda mumunda, tanga watarisa kana inki roller pressure yakarurama kuti uone kuti inki roller haina glaze;Simbisa kuti maitiro ekugadzirisa echitubu mhinduro ndeyechokwadi;Pamusoro pegumbeze pachava pasina tsvina, mapini, nezvimwewo .. Uyezve, bvunzo yakaratidza kuti kudzvanywa kwemhepo kweboka mushure menzvimbo yakakura kudhinda kuchaita nekukurumidza pakuvandudza kutsetseka kwenzvimbo huru yekudhinda.
Inki kumashure dhonza
Mukudhinda kweUV offset, inki yekudzosera kumashure kukundikana kwakajairika, kunyanya nekuti UV offset inodhinda inki haina kuporeswa zvizere mushure me UV irradiation, uye haina kubatanidzwa zvakasimba kune substrate.Pasi pekuita kwekumanikidza kwekudhinda kweanotevera mavara madhiketi, iyo inki inodhonzwa kumusoro uye yakanamatira kune gumbeze remamwe mavara madhiki.
Kana inki yekudhonza kumashure ikaitika, inogona kazhinji kugadziriswa nekudzikisa mvura yeUV inorapa ruvara boka, kuwedzera mvura yeiki yekudhirowa kwemavara boka, uye kuderedza kudhinda kudhindwa kweboka remavara einki;Kana dambudziko richiri kutadza kugadziriswa, ripore neUV
Dambudziko iri rinogona kuvandudzwa nekuwedzera chiyero chakakodzera che tensile agent kune inki yedeki yemavara.Mukuwedzera, kuchembera kwegumbeze rerubha zvakare chikonzero chakakosha cheiyo inki kumashure kudhonza chiitiko.
Kudhinda kwakashata kwebhakodhi
Kudhinda kweUV offset yemapakeji efodya, mhando yekudhindwa kwebhakodhi chiratidzo chakakosha.Zvakare, nekuda kwekuratidzwa kwakasimba kwegoridhe nesirivheri kadhibhodhi kuchiedza, zviri nyore kuita kuti iyo bar kodhi yekuona ive isina kugadzikana kana kutodzika.Kazhinji, kune maviri makuru mamiriro apo iyo UV yekubvisa bhakodhi yefodya pasuru inotadza kusangana neyakajairwa: defect degree uye decoding degree.Kana dhigirii rakaremara risati rasvika pachiyero, tarisa kana inki chena yakadhinda yakatsetseka uye kana bepa rakavharwa zvachose;Kana iyo decodeability isiri kusvika pachiyero, tarisa inki emulsification yebhakodhi yekudhinda ruvara dhizaini uye kana bhakodhi ine ghosting.
UV offset kudhinda ingi dzine mavara akasiyana siyana ane akasiyana transmittance kune UV.Kazhinji, UV iri nyore kupinda yero uye magenta UV offset kudhinda ingi, asi zvakaoma kupinza cyan uye dema UV offset kudhinda ingi, kunyanya dema UV offset kudhinda ingi.Naizvozvo, mu UV offset kudhinda, kana ukobvu hweblack UV offset inki ichiwedzerwa kuti ivandudze kudhinda kwebhakodhi, zvinokonzeresa kuoma kuoma kweinki, kusanamira zvakanaka kweinki layer, kudonha nyore, uye kunyangwe kuipa. adhesion.
Naizvozvo, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune ukobvu hweiyo inki nhema mu UV offset kudhinda kudzivirira bhakodhi kubva kunamira.
Kuchengetera UV offset kudhinda inki
UV offset kudhinda inki inofanirwa kuchengetwa munzvimbo ine rima iri pasi pe25 ℃.Kana ikachengetwa pane tembiricha yakakwira, UV offset printing inki inoomesa nekuomesa.Kunyanya, UV inobvisa goridhe uye sirivheri inki inowanzoita kusimba uye kushata kupenya kupfuura general UV offset inki, saka zviri nani kuti urege kuichengeta kwenguva yakareba.
Muchidimbu, iyo UV offset kudhinda maitiro inonetsa kugona.Iwo matekinoroji emabhizinesi ekudhinda mapakeji efodya anofanirwa kunyatso cherechedza uye kupfupisa mukugadzirwa kwekudhinda.Pahwaro hwekugona imwe inodiwa ruzivo rwedzidziso, kubatanidza dzidziso uye ruzivo rwakanyanya kugadzirisa matambudziko anowanikwa muUV offset kudhinda.
