Mvura, firimu rakareruka kana matte anodhinda anonamirwa mabhodhoro ane mavara

Iko kushandiswa kwakakura kwemavara uye kuenderera mberi kwekusimudzira kwemhando dzema label kunosimudzira kusimudzira tekinoroji yekudhinda.Label kudhinda inovhara flat, convex, concave, mesh nedzimwe nzira dzekudhinda, kushandiswa kwenyika dzakasiyana hakuna kufanana.Nekudaro, zvinogona kuoneka kubva mukusimukira kwemavara epasi rose mumakore achangopfuura kuti flexographic printing, nhete-range rotary printing uye kudhinda kwedhijitari zvave zvitsva zvinopenya zvekudhindwa kwemabhii munyika dzeEurope neAmerica, uye zvakare nzira yekuvandudza yezita. kudhinda.

Prepress processing

Muchikamu che pre-press processing, akawanda maodha akagadzirwa nevatengi anonyanya kudhinda offset kana gravure kudhinda.Kana flexo kudhinda kwakagamuchirwa kune rudzi urwu rwezvinyorwa, matambudziko akawanda ehutano achaitika mumuenzaniso, sekuti ruvara rusina nzvimbo, zvidimbu hazvisi pachena, uye mipendero yakaoma inooneka.Nokudaro, kugadzirisa matambudziko akadaro, kutaurirana nenguva nevatengi kunokosha zvikuru.

Mazuva ano, kudhindwa kwemavara kunoitwa nemaoko, uye mavara akawanda e monochrome anoitwa nemichina .Iyo inogona kuvandudza kushanda kwekugadzira.Kunyange zvazvo kururama kwokudhinda kwemichina mizhinji ichangobva kugadzirwa yokutsikirira mabhii hakuna kukwirira, kwakavandudza unyanzvi hwokudhinda uye kunaka kwokudhinda kunoda kuvandudzwa.

Plate kugadzira process

Kudhinda label kunovhara nzira dzakati wandei dzekudhinda padanho rekugadzira plate.Zvinoenderana nemasikirwo akasiyana echigadzirwa, sarudza nzira dzakasiyana dzekudhinda, zvinoenderana neakasiyana nzira dzekudhinda, ndiro - kugadzira maitiro zvakare akasiyana.Iri bepa rinotora nzira yekugadzira ndiro inochinjika semuenzaniso kuita sumo pfupi.

Iyo nzira yekuyerera kweinochinjika plate-making ndeiyi inotevera: yepakutanga manuscript (artwork), firimu (negative firimu), kuratidzwa, sukurudza, kuomesa uye kurapwa.

1. Manyoro(mifananidzo).Chimiro chepakutanga chakakodzera kudhinda kunoshanduka kunofanira kuva nemhando dzinotevera: nhamba huru yemavara.Asi zvishoma overprint;Hapana chinodiwa kubereka kunyanya zvidiki zvidiki;Iyo tambo haina kunyanya kukwira, asi inogona kuwana ruvara kudhinda maitiro;Packaging processing inogona kuitwa online.

2. Firimu (negative film).Sangana nezvinodiwa zvekugadzira ndiro, mifananidzo yakajeka uye zvinyorwa, saizi chaiyo yakatarwa;Nematte firimu, kuwanda kwemakona mana efirimu kunofanira kuenderana.Kushandiswa kwezvinodhaka firimu orthografia;Iyo chena inogoneka density yaive pazasi 0.06 kuyerwa neiyo transmission density mita.The black bit density iri pamusoro pe3.5.

3. Kuratidzira kunosanganisira kuratidzwa kumashure uye kuratidzwa kukuru.

Kuratidzira kumashure.Photosensitive resin vhezheni yefirimu rinotsigira kumusoro, firimu rekudzivirira pasi tile mudhirowa rekuratidzwa kuti rigamuchire kuratidzwa.Uv mwenje inopinda mufirimu rinotsigira kusimbisa iyo photosensitive adhesive layer.Kugadzira hwaro hwakasimba, inogona zvakare kudzora kudzika kwekugeza, kusimbisa chisungo pakati peinotsigira firimu uye photosensitive resin layer.Nguva yekudzoka shure inotarirwa maererano nehupamhi hunodiwa hwaro.

Main exposure.Iyo inozivikanwawo sekuratidzwa kwepamberi, photosensitive resin plate zvinhu inotsigira firimu pasi, inodzivirira firimu kumusoro.Yakaiswa mataira muexposure drawer.Bvisa firimu rekudzivirira kamwechete mumutsara, wozoisa iyo firimu pamusoro peiyo photosensitive resin ndiro.Nzira yekuedza inoshandiswa kufirimu (firimu risiri rezvinodhaka rinovharwa kuita kuti firimu rinyatsonamatira kune photosensitive resin layer. Iyo ultraviolet mwaranzi inopinda muvacuum firimu uye firimu rakajeka chikamu, chinoita kuti ndiro iyo photosensitive chikamu chepolymerization chiome. Hurefu hwenguva yekuratidzwa huru hunotariswa nerudzi rwendiro uye kusimba kwechiedza.Nguva yekuratidzwa ipfupi kwazvo ichaita kuti girafu nemateru emavara anyanyotwasanuka, mitsetse yakakomberedzwa, mazwi madiki, zvidiki zvinosukwa, pane kudaro. , nguva yekuratidzira yakarebesa ichashanda shanduro, manyorero haana kujeka , kuve nechokwadi chemhando yeplate.

4. Shamba.Geza iyo photosensitive chikamu chemhinduro, chengetedza iyo mwenje polymerization yekuyamura.Hurefu hwenguva yekugeza zvinoenderana nekukora kweplate uye kudzika kwekudhindwa, nguva yekugeza ipfupi, ndiro inosiya isina photosensitive resin uye inokanganisa kudzika kweplate, nguva yekugeza yakarebesa ichaita. kuwedzera kweplate, zvichiita kuti chikamu chakanaka deformation kana kudonha.

5. Kuomesa.Bvisa washing solvent, kuitira kuti ndiro idzorere hukuru hwepakutanga hwehupamhi.Kupisa kwekubikira kuri pakati pe50-60 ℃.Nguva yekubikira zvichienderana nekukora kwendiro uye geza kureba kwenguva yekuona, iyo yakawanda gobvu shanduro yemaawa maviri, yakaonda shanduro yeawa.Nguva yekubika yakarebesa, tembiricha yekubikira yakakwira zvakanyanya ichaita kuti ndiro iite brittle uye kukanganisa hupenyu hwekudhinda.Kubikira tembiricha yakadzikira kunowedzera nguva yekuomeswa, nguva yekubika ipfupi, kudhinda kuchaonekwa kwakaora shanduro chiitiko.

6. Post-processing.Ndiko, mushure mekubviswa kwekunamatira uye kuratidzwa.Ita iyo photosensitive resin yakaomeswa zvachose (polymerized) kuti uwane iyo yakafanira kuomarara indekisi, uye kubvisa ndiro viscosity, kuitira kuti kufambisa kufambiswa kweinki.Nguva yekurapwa yakawanikwa nekuongororwa nechinangwa chekusatsemuka kana kunamira.
