Gravure mbale kupanga njira ya rotogravure makina osindikizira

Makina osindikizira a Rotogravureengraving gravure ndi chojambula chopangidwa ndi chojambula pamanja kapena chamakina, ndipo ndi njira yakale kwambiri yopangira mbale mu makina osindikizira a Rotogravure.Pakadali pano, makina osindikizira amtundu wa Rotogravure sagwiritsidwa ntchito kawirikawiri, ndipo chojambula chamagetsi ndi mbale yosindikizira yomwe imagwiritsidwa ntchito kwambiri pantchito yosindikiza ma gravure.Kenako, tiyeni tiwone njira yopangira ma gravure makina osindikizira a Rotogravure ndiJINYI

1. Makina osindikizira a RotogravureGravure kupanga mapulanetiKujambula ndi manja

Makina osindikizira a RotogravureGravure mbale kupanga Buku chosema njira akhoza kugawidwa mu mitundu iwiri: chosema njira ndi etching njira.Mu makina osindikizira a Rotogravure makina osindikizira, chojambula chachindunji chojambula ndi chojambula pamanja ndi mpeni, ndipo mbale yoyambirira ya gravure ya fano imapangidwa mwachindunji;Makina osindikizira a Rotogravure ndi njira yopangira mwachindunji mbale ya gravure pogubuduza pa mbale yokhala ndi chida chojambulira monga fosholo yomata ndikupanga yunifolomu yabwino yokhotakhota ndi grit yopingasa pamwamba pa mbale kuti mbale ya shading igwiritse ntchito.Chovala chokhazikika cha intaglio mu njira yosindikizira ya Rotogravure ndikuphimba filimu yotsutsa-kuwononga pa mbale yachitsulo, ndikuyilemba pamanja ndi singano yotsekera, kuyika filimu yotsutsa dzimbiri, ndikupeza zithunzi ndi zolemba pogwiritsa ntchito mankhwala. njira.Mzere gravure, amene angathe kusindikiza malankhulidwe ofewa;Rotogravure makina osindikizira etching njira ndi mtundu wa etching gravure, pa mbale pansi, mwa makina ndi njira zamanja, kuwaza utomoni kapena phula ufa, ndi kutentha kukonza ufa Pa mbale, chithunzi cholakwika ndiye cholembedwa ndi kukana, ndi chithunzi gravure amapangidwa ndi etching njira.

Negative chithunzi, chithunzi gravure opangidwa ndi etching njira.

2. Makina osindikizira a Rotogravure Kupanga mbale yamagetsi yamagetsi

Makina osindikizira a RotogravureNjira zojambulira ma elekitironi ndi njira yosinthira ma siginecha owoneka kapena a digito kukhala oyenda pamakina kudzera pakusintha kwazithunzi (kutembenuka kwa digito-to-analogi) ndi kutembenuka kwamagetsi.Jenereta yafupipafupi imagwiritsidwa ntchito kupanga oscillation ndi ma frequency (4-8kHz) ndi matalikidwe oyenera.Pambuyo pa chizindikiro cha digito cha kukumbukira kwachithunzichi kumasinthidwa kukhala chizindikiro cha analogi ndi chosinthira digito-to-analoji, chimaphatikizidwa ndi matalikidwe a chinthu cham'mbuyo kuti chiwongolere mpeni wojambula kuti uzizungulira mofulumira.Pamwamba pa mbale-kupanga mkuwa wosanjikiza wa mbale wodzigudubuza cholembedwa ndi maselo osiyanasiyana kukula ndi kuya.Makina osindikizira a Rotogravure Mfundo yopangira mbale yamagetsi yamagetsi ndiyoti makina ojambulira amagetsi amatha kuwongolera molondola kuchuluka kwa mizere yotchinga ndi ngodya yotchinga powongolera kuthamanga kwa ng'oma ndi kuthamanga kwapambuyo kwa mutu wojambula kuti agwirizane ndi chojambulacho. pafupipafupi.

Kupanga mbale yamagetsi yamagetsi ndipamene makina osindikizira a Rotogravure amajambula mwachindunji mbale yomwe ikupanga pa ng'oma molingana ndi chidziwitso cha digito chopangidwa ndi makina osindikizira apakompyuta.Mfundo yogwiritsira ntchito makina osindikizira a digito mu makina osindikizira amagetsi opanda mafilimu: Makina osindikizira a Rotogravure opanda mafilimu opanga mapepala amagetsi ndi oyamba kuzindikira bwino luso la CTP mu njira zonse zosindikizira mbale.Makina osindikizira a Rotogravure opanda filimu akupanga mbale zojambulira pakompyuta: masanjidwe amasamba a digito → kuyika magawo → chosema choyeserera → chosema chokhazikika.

Kuyika: Pamalo opangira ntchito, malinga ndi zofunikira za makina osindikizira a Rotogravure, masamba omwe adasindikizidwa kale amasonkhanitsidwa m'mafayilo amtundu waukulu kuti ajambule molingana ndi kapangidwe kake, ndipo nthawi yomweyo, kuwongolera kwa post-process. kuwongolera kumayikidwa pamapangidwe osonkhanitsidwa.chizindikiro.Zizindikiro zowongolera zimaphatikizanso zolembera zowongolera zolondola mopitilira muyeso, zodula zowongolera kudula kwa makina osindikizira a Rotogravure, ndi zina zambiri.

Kuyika kwa parameter: Khazikitsani chipika chojambulira, mzere wa mauna, ngodya ya mauna, ndi zina zambiri mu makina osindikizira a Rotogravure amagetsi owongolera.

Kujambula kwa mayesero: Cholinga chake ndikusintha makina osindikizira a Rotogravure (kukhazikitsa matalikidwe, kuwala kwamakono ndi kusintha kwakuda) kotero kuti kamvekedwe kakuda kakuda, kuwala kwakukulu, ndi kuyankhulana zigwirizane ndi zofunikira.

Zolemba zokhazikika: Zolembazo zikasinthidwa kukhala mtengo woyenera pambuyo pa makina osindikizira a Rotogravure, malo oyambira akhoza kukhazikitsidwa ndipo zolemba zovomerezeka zitha kuyambika.

3. Makina osindikizira a Rotogravure Ultra-fine electronic chojambula luso

Kuphatikiza pa makina awiri osindikizira a Rotogravure electro-engraving njira zomwe tafotokozazi, zatsopanoMakina osindikizira a RotogravureNjira yojambulira pakompyuta yapezedwa: XT (Xtreme Engraving) njira yojambulira kwambiri yamagetsi yamagetsi.Ukadaulo wa XT Ultra Fine Electronic Engraving umagwiritsa ntchito zolemba zowoneka bwino kwambiri pamawu ndi zinthu zabwino zojambulira.Makina osindikizira a Rotogravure amatengera ukadaulo wa XT wotsogola kwambiri.Poganizira kuti mutu wojambula umakhalabe wosasinthika, chojambula chojambula cha makina ochiritsira ochiritsira amawonjezeka kufika pa mizere 200 / masentimita;ndi makina chosema pakompyuta ntchito m'munda wa chitetezo, chitukuko chapadera akhoza anatengera.The chosema mutu kumawonjezera chosema kusamvana kwa 2000 mizere/cm.Makina osindikizira a Rotogravure The ultrafine electronic engraving technology imafuna chowongolera chophimba, chomwe chimayikidwa pamutu wa XT chojambula, ndipo chinsalucho chimalembedwa nthawi yomweyo.Selo limodzi la chozokotedwali limapangidwa ndi mizere ingapo yozokotedwa.Chiwerengero cha mizere ya selo chosema ndi chimodzimodzi The chosema kusamvana kungakhale kosiyana.Chizindikiro chojambula chokwera kwambiri cha mzere uliwonse chiyenera kukhala ndi udindo wopanga mkati mwa concave contour.Maonekedwe a selo lotseguka lopangidwa ndi kuphatikiza kwa mizere ingapo yozokotedwa amayeneranso kutsimikiziridwa ndi deta yojambula.Motsogozedwa ndi data ya grayscale, ma cell okhala ndi ngodya zosiyanasiyana zowonekera komanso mawonekedwe otsegulira amatha kupangidwa momasuka, ndipo ngakhale kuwunika pafupipafupi kutha kuchitidwa chifukwa mawonekedwe a cell ndi ngodya zimamasulidwa ku zopinga za "selo imodzi panthawi imodzi. ” njira.kukonza, ndipo pamapeto pake kuzindikira kutulutsa kwazithunzi za FM.

Zomwe zili pamwambazi ndizomwe zili m'makina osindikizira a Rotogravure opanga ma gravure omwe abweretsedwa kwa inu lero ndiJINYI.Ndikukhulupirira kuti nditawerenga malemba onse, aliyense ali ndi chidziwitso cha njira yopangira gravure plate, njira yopangira mbale yamagetsi ndi luso lamakono lamakono lamagetsi, ndi zambiri Zambiri zimasinthidwa mosalekeza, tiwonane m'magazini yotsatira.
