Inki yekudhinda ine gravure yemvura inooma kana munhu achishandisa nzira chaiyo, kureva, kuburikidza nekubuda kwezvinonyungudutsa, uye inki yezvikamu zviviri kuburikidza nekushandisa makemikari.
Chii chinonzi Gravure Printing
Inki yekudhinda ine gravure yemvura inooma kana munhu achishandisa nzira chaiyo, kureva, kuburikidza nekubuda kwezvinonyungudutsa, uye inki yezvikamu zviviri kuburikidza nekushandisa makemikari.
Ndezvipi zvakanakira uye zvakaipa zvekudhinda gravure.
Hunhu hwepamusoro hwekudhindwa
Huwandu hweinki inoshandiswa mukudhinda gravure hwakakura, mifananidzo nemagwaro zvine kunzwa kwakapfava, uye zvikamu zvakapfuma, mitsetse yakajeka, uye mhando yacho yakakwirira. Kudhindwa kwakawanda kwemabhuku, magazini, mifananidzo, kurongedza nekushongedza kunodhindwa gravure.
Kudhinda kwepamusoro-soro
Kudhinda kwegravure kwenguva refu, kushanda kwayo kwakaderera, uye mutengo wayo wakakwira. Zvisinei, dhinda rekudhinda rinogara kwenguva refu, saka rakakodzera kudhinda zvakawanda. Kana bhachi rakakura, zvinobatsira zvakawanda, uye kana kudhinda nebhachi diki, zvinobatsira zvishoma. Saka, nzira yegravure haina kukodzera kudhinda mabhachi madiki ezviratidzo.
(1) Zvakanakira: inki inobuda inenge 90%, uye ruvara rwayo rwakawanda. Kubereka mavara kwakasimba. Kuramba kwakasimba pakurongwa. Huwandu hwemaprinta hwakakura. Kushandiswa kwemapepa akasiyana-siyana, kunze kwepepa, kunogonawo kudhindwa.
(2) Zvakashata: mari yekugadzira mapuratifomu inodhura, mari yekudhinda inodhurawo, basa rekugadzira mapuratifomu rakaoma, uye makopi mashoma akadhindwa haana kukodzera.
Zvigadziko
Gravure inogona kushandiswa mumhando dzakasiyana-siyana dzezvinhu, asi inowanzoshandiswa kudhinda bepa repamusoro nepurasitiki.
Kuonekwa kwemaprinta: Marongerwo acho akachena, akafanana, uye hapana mavara etsvina ari pachena. Mifananidzo nemagwaro zvakaiswa zvakanaka. Ruvara rweplate yekudhinda rwakafanana, kukanganisa kwehukuru hwekudhinda kwakanaka hakupfuuri 0.5mm, kudhinda kwakajairika hakupfuuri 1.0mm, uye kukanganisa kwekudhinda kwepamusoro kwemativi ekumberi nekumashure hakupfuuri 1.0mm
Mibvunzo Inowanzo bvunzwa
Kukundikana kwekudhinda gravure kunonyanya kukonzerwa nemaplate ekudhinda, inki, substrates, vanotsvedza, nezvimwewo.
(1) Ruvara rweinki rwakajeka uye haruna kuenzana
Kuchinja kwemavara einki nguva nenguva kunoitika pazvinhu zvakadhindwa. Nzira dzekubvisa dzinosanganisira: kugadzirisa kutenderera kweplate roller, kugadzirisa kona nekumanikidzwa kwe squeegee kana kuitsiva neimwe itsva.
(ii) Chiratidzo chacho chine hunyoro uye chine mvere
Mufananidzo wechinhu chakadhindwa wakanyorwa nemagiredhi uye wakagadzirwa nependi, uye mupendero wemufananidzo nerugwaro zvinoita semaburi. Nzira dzekubvisa ndeidzi: kubvisa magetsi asingachinji pamusoro pe substrate, kuwedzera zvinonyungudutsa zve polar kuinki, kuwedzera kumanikidzwa kwekudhinda zvakakodzera, kugadzirisa nzvimbo ye squeegee, nezvimwewo.
3) Chiitiko chekuti inki inovhara inooma mugomba remambure epureti yekudhinda, kana kuti gomba remambure epureti yekudhinda rakazadzwa nebvudzi repepa nehupfu hwepepa, chinonzi blocking plate. Nzira dzekubvisa ndeidzi: kuwedzera huwandu hwezvinonyungudutsa muinki, kuderedza kumhanya kwekuoma kweinki, uye kudhinda nepepa rine simba guru pamusoro.
4) Kudururwa kweinki uye kudonhedzwa kwemavara pachikamu chechinhu chakadhindwa. Nzira dzekubvisa ndeidzi: kuwedzera mafuta einki yakaoma kuti iwedzere kunaka kweinki. Gadzirisa kona yechinhu chinotsvedza, wedzera kumhanya kwekudhinda, tsiva plate yekudhinda ine mesh yakadzika neplate yekudhinda ine mesh shoma, nezvimwewo.
5) Zviratidzo zvekukwenya: Zviratidzo zvekukwenya pachinhu chakadhindwa. Nzira dzekubvisa dzinosanganisira kudhinda neingi dzakachena pasina kupinda kwezvinhu zvekunze. Gadzirisa kusimba kweinki, kuoma kwayo, uye kunamira kwayo. Shandisa squeegee yemhando yepamusoro kugadzirisa kona iri pakati pe squeegee neplate.
6) Kunaya kwemvura muruvara rweganda
Chiitiko chekujekesa ruvara papepa. Nzira dzekubvisa mavara ndeidzi: kudhinda neinki dzine kupararira kwakanaka uye kushanda kwakasimba. Zvinowedzera zvinopesana nekubatana kwemavara uye zvinopesana nemvura zvinowedzerwa kuinki. Peta zvakanaka wobva wasanganisa inki iri mutangi reinki nguva nenguva.
(7) Chiitiko chemavara einki pazvinhu zvakadhindwa zvinonamira. Nzira dzekubvisa ndeidzi: sarudza kudhinda inki nekukurumidza kuputika, wedzera tembiricha yekuomesa kana kuderedza kumhanya kwekudhinda zvakakodzera.
(8) Kubviswa kweinki
Ingi yakadhindwa pafirimu repurasitiki haina kunamira zvakanaka uye inokweshwa nemaoko kana nesimba remuchina. Nzira dzekubvisa ndeidzi: kudzivirira firimu repurasitiki kubva muhunyoro, kusarudza kudhinda kweinki kwakabatana zvakanaka nefirimu repurasitiki, kudzorera firimu repurasitiki pamusoro, uye kugadzirisa kusimba kwepamusoro.
Mafambiro ebudiriro
Nekuda kwekuchengetedzwa kwezvakatipoteredza nezvikonzero zvehutano, chikafu, mishonga, fodya, doro nedzimwe nzvimbo dzeindasitiri dziri kuramba dzichitarisa kuchengetedzwa kwezvakatipoteredza kwezvinhu zvekurongedza nekudhinda, uye makambani ekudhinda gravure ari kunyanya kutarisa nharaunda yemabasa ekudhinda. Inki nemavhanishi zvine hushamwari kune zvakatipoteredza zvichawedzera kufarirwa, masisitimu ekuvhara akavharwa uye zvishandiso zvinokurumidza kuchinja zvichawedzerwa mukurumbira, uye michina yekudhinda gravure yakagadziriswa neinki dzemvura ichashandiswa zvakanyanya.
