Ingi yekudhinda yemvura inoomesa kana munhu ashandisa nzira yemuviri, ndiko kuti, nekubuda kwezvinonyungudutsa, uye ingi dzezvikamu zviviri nekurapa kwekemikari.
Ndezvipi zvakanakira uye zvakaipira gravure kudhinda.
Kudhinda kwepamusoro
Huwandu hweinki inoshandiswa pakudhinda pagravure yakakura, magirafu uye zvinyorwa zvine manzwiro econvex, uye zvidimbu zvakapfuma, mitsetse yakajeka, uye mhando yepamusoro. Kunyanya kudhindwa kwemabhuku, magazini, mapikicha, kurongedza uye kushongedzwa kudhindwa kwegravure.
Kudhinda kwevhoriyamu yakakwirira
Iyo ndiro yekugadzira kutenderera kwegravure kudhinda yakareba, kushanda kwacho kwakaderera, uye mutengo wakakwira. Zvisinei, ndiro yekudhinda inogara kwenguva refu, saka yakakodzera kudhinda kukuru. Iyo yakakura batch, iyo yakakwira kubatsirwa, uye kudhinda nebatch diki, kubatsirwa kwakaderera. Nokudaro, nzira ye gravure haina kukodzera kudhindwa kwezvikwata zviduku zvezviratidzo.
(1) Zvakanakira: iyo inki kutaura ndeye 90%, uye ruvara rwakapfuma. Kubereka kwakasimba kwemavara. Kuramba kwakasimba kwegadziriro. Nhamba yezvinyorwa zvakakura. Kushandiswa kwemapepa akasiyana-siyana, kunze kwezvinyorwa zvemapepa zvinogonawo kudhindwa.
(2) Zvakaipa: mari yekugadzira plate inodhura, mari yokudhinda inodhurawo, basa rokugadzira ndiro rakaoma kunzwisisa, uye nhamba shoma yemakopi akadhindwa haakodzeri.
Substrates
Gravure inogona kushandiswa mumhando dzakasiyana-siyana, asi inowanzoshandiswa kudhinda mapepa epamusoro-giredhi uye firimu repurasitiki.
Kuonekwa kwemaprints: Mamiriro acho akachena, yunifomu, uye hapana mavara etsvina ari pachena. Mifananidzo uye zvinyorwa zvakamisikidzwa nemazvo. Ruvara rwepureti yekudhinda yakangofanana, saizi yekukanganisa kudhinda yakanaka haina kupfuura 0.5mm, kudhinda kwese hakuna kupfuura 1.0mm, uye kukanganisa kwekupfuura kwemberi uye kumashure mativi hakupfuuri 1.0mm.
FAQ
Kukundikana mukudhindwa kwegravure kunonyanya kukonzerwa nekudhinda mahwendefa, ingi, substrates, squeegists, nezvimwe.
(1) Ingi ruvara rwakareruka uye haruna kuenzana
Kuchinja kweruvara rweinki nguva nenguva kunoitika pazvinhu zvakadhindwa. Nzira dzekubvisa dzinosanganisira: kururamisa kutenderera kweplate roller, kugadzirisa kona uye kumanikidzika kwe squeegee kana kuitsiva neimwe itsva.
(ii) Chimiro chine mushy uye chine mvere
Mufananidzo weiyo yakadhindwa yakagadziridzwa uye yakanamatira, uye mupendero wemufananidzo uye zvinyorwa zvinoratidzika burrs. Nzira dzekubvisa ndeidzi: kubvisa static magetsi pamusoro pe substrate, kuwedzera polar solvents kune inki, zvakakodzera kuwedzera kudhindwa kwekudhinda, kugadzirisa nzvimbo ye squeegee, nezvimwewo.
3) Chiitiko chekuti inki inovharira inoomesa mukati me mesh mhango yendiro yekudhinda, kana mesh mhango yeplate yekudhinda yakazadzwa nemvere dzepepa nehupfu hwepepa, inonzi kuvharira ndiro. Nzira dzekubvisa ndeidzi: kuwedzera zvinyorwa zvezvinonyungudutsa muinki, kuderedza kukurumidza kwekuomesa inki, uye kudhinda nepepa rine simba guru.
4) Kuparara kweingi uye kuona pamunda chikamu chechinhu chakadhindwa. Nzira dzekubvisa ndeidzi: kuwedzera mafuta einki yakaoma kuvandudza viscosity yeinki. Gadzirisa kona ye squeegee, wedzera kumhanya kwekudhinda, tsiva yakadzika mesh yekudhinda ndiro ine isina kudzika mesh yekudhinda ndiro, nezvimwe.
5) Kukwenya mamaki: Maronda emusvina pane zvakadhindwa. Nzira dzekubvisa dzinosanganisira kudhinda neingi dzakachena pasina kunze kwenyika ingress. Gadzirisa viscosity, kuoma, kunamatira kweinki. Shandisa yepamusoro-soro kuti ugadzirise kona pakati pekusvina uye ndiro.
6) Pigment kunaya
Chiitiko chekujekesa ruvara pane zvakadhindwa. Nzira dzekubvisa ndeidzi: kudhinda neinki nekupararira kwakanaka uye kushanda kwakagadzikana. Anti-agglomeration uye anti-precipitation additives inowedzerwa kune inki. Peta zvakanaka uye simbisa ingi mutangi yeinki nguva nenguva.
(7) Chiitiko chemavara engi pane zvakanamira zvakadhindwa. Nzira dzekubvisa ndeidzi: sarudza inki kudhinda nekukurumidza volatilization kumhanya, wedzera kuomesa tembiricha kana kudzikisa zvakakodzera kumhanya kwekudhinda.
(8) Kuteura ingi
Ingi yakadhindwa pafirimu repurasitiki haina kumira zvakanaka uye inokwizwa nemaoko kana kuti mechanical force. Nzira dzekubvisa ndeidzi: kudzivirira firimu repurasitiki kubva kunyoro, sarudza inki kudhindwa nehukama hwakanaka nefirimu repurasitiki, tarisazve firimu repurasitiki, uye gadzirisa kushushikana kwepasi.
Mafambiro ebudiriro
Nekuda kwekuchengetedzwa kwezvakatipoteredza uye zvikonzero zvehutano, chikafu, mushonga, fodya, doro uye mamwe maindasitiri anobhadhara zvakanyanya uye zvakanyanya kutarisisa kuchengetedzwa kwezvakatipoteredza kwezvinhu zvekurongedza uye maitiro ekudhinda, uye mabhizinesi ekudhinda gravure anonyanya kutarisisa kunharaunda yemashopu ekudhinda. Inki nemavhanishi ane ushamwari kwezvakatipoteredza zvichawedzera kufarirwa, masisitimu akavharwa uye zvishandiso zvekuchinja nekukurumidza zvichave zvakakurumbira, uye zvitsikiro zvegravure zvakachinjirwa kumaingi emvura zvichashandiswa zvakanyanya.
