Chiyambi cha Njira Yosindikizira ya Rotogravure

Kodi rotogravure printing ndi chiyani?

Gravure kusindikiza ndi kupanga padziko lonse la mbale yosindikizira yokutidwa ndi inki, ndiyeno ntchito yapadera kukala limagwirira kuchotsa inki ku chopanda kanthu mbali ya inki, kotero kuti inki yekha waikamo mu mauna cavities wa zojambulajambula mbali ya inki, ndiyeno pansi pa zochita za chitsenderezo chachikulu, inki adzakhala anasamutsidwa ndi substrate pamwamba pa nkhani. Kusindikiza kwa Gravure ndikusindikiza mwachindunji. Gawo lojambula la mbale yosindikizira ndi concave, ndipo mlingo wa concavity ndi msinkhu wa chithunzicho uli ndi mithunzi yosiyana, gawo lopanda kanthu la mbale yosindikizira limakwezedwa, ndipo mu ndege imodzi ya silinda.

Njira ya rotogravure ndi njira yosamutsira mwachindunji yosindikizira pamitengo yamatabwa, yopangidwa, kapena yopangidwa ndi laminated, kuphatikiza:

-Makanema monga PET, OPP, nayiloni, ndi PE,PVC, Cellophane

- Mapepala

- Bokosi la makatoni

- Chojambula cha aluminium

Rotogravure kusindikiza ndondomeko

Kusindikiza kwa Rotogravure chifukwa cha kuchuluka kwa makina osindikizira, mtundu wa mbaleyo ndi wabwino, motero ntchitoyo ndiyosavuta kuposa kusindikiza kwa lithographic, yosavuta kuidziwa, njira yoyendera ndi motere:

Kukonzekera kusindikiza kale → pa silinda → sinthani kalembera wa mtundu → kusindikiza kovomerezeka → kusindikiza pambuyo posindikiza

Kufotokozera ndondomeko

Pa gravure kusindikiza ndondomeko yosindikizira yamphamvu amazungulira mu inki poto kumene lolembedwa maselo amadzaza ndi inki. Pamene silinda imazungulira bwino pa poto ya inki, inki yowonjezereka imachotsedwa ndi tsamba la dokotala. Kupitilira apo, silindayo imalumikizidwa ndi gawo lapansi, lomwe limakanikizidwa ndi mphira wophimbidwa ndi mphira.

Kupanikizika kwa wodzigudubuza, pamodzi ndi capillary draw of the substrate, kumabweretsa kusuntha kwa inki mwachindunji kuchokera ku maselo mu silinda yosindikizira kupita pamwamba pa gawo lapansi. Pamene chogudubuza chosindikizira chikuzunguliranso mu poto ya inki, malo osindikizidwa a gawo lapansi amadutsa mu chowumitsira ndi kupita ku gawo lotsatira losindikizira, lomwe nthawi zambiri limakhala la mtundu wosiyana kapena lingakhale varnish kapena zokutira.

Kulembetsa kwamtundu wolondola kwamitundu kumatheka kudzera pamakina owongolera ambali ndi kutalika.

Pa makina osindikizira a pa intaneti, mtundu uliwonse ukasindikizidwa ndi zokutira zilizonse, ukonde 'umapangidwanso' kukhala mpukutu womalizidwa.

Tsopano timayang'ana pa kusindikiza kungakhudze mwachindunji khalidwe losindikiza la chimodzi mwazofunikira kwambiri - kulembetsa mtundu

Masiku ano, makina ambiri osindikizira a gravure adzagwiritsa ntchito makina olembetsa amtundu wodziyimira pawokha polembetsa mawonekedwe, zomwe zimathandizira kwambiri kulembetsa bwino komanso kusindikiza.

Pa makina osindikizira a web gravure, pali chida chodziwikiratu choyikapo. Chipangizocho chimakhala ndi mutu wojambulira, jenereta ya pulse, chowongolera zamagetsi, mota yosinthira, chowongolera chowongolera mopitilira muyeso ndi zina zotero.

Pamene overprint chizindikiro pa pepala kusindikizidwa kudzera mutu sikani, ndi zimachitika chizindikiro adzakhala opatsirana kwa Mtsogoleri zamagetsi, ngati mtundu wachiwiri wa overprint chizindikiro cholakwika isanayambe kapena itatha mtundu woyamba wa chizindikiro, zimachitika kugunda kwa nthawi adzakhala m'njira zosiyanasiyana, kotero Mtsogoleri zamagetsi kuyamba kulamulira galimoto, kuti mtundu woyamba ndi mtundu wachiwiri wa overprints cholakwa chochepa pakati pa mpukutu wopukutira, kuchotsa zolakwa zazing'ono.

Kuonjezera apo, palinso zinthu zotsatirazi zomwe zingakhudze khalidwe ndi luso la kusindikiza, koma tidzakhala ndi mayankho oyenera.

a) Inki ndi yosiyana mu mtundu

Chodabwitsa cha mtundu wa inki wanthawi ndi nthawi umasintha pazinthu zosindikizidwa. Njira zochotseramo zikuphatikizapo: kukonza kuzungulira kwa silinda ya mbale yosindikizira, kusintha ngodya ndi kupanikizika kwa squeegee kapena kusintha squeegee ndi yatsopano.

b) Zojambula zosamveka komanso za linty

Magawo azithunzi osindikizidwa ndi mulingo, phala, chodabwitsa cha ma burrs pamphepete mwa chithunzicho. Njira zochotsera zikuphatikizapo: kuchotsa magetsi osasunthika pamwamba pa gawo lapansi, kuwonjezera zosungunulira za polar ku inki, moyenerera kuwonjezera kukakamiza kusindikiza, ndi kusintha malo a squeegee ndi zina zotero.

c) mtundu woletsedwa

Kuunika kwa inki mu mesh yosindikizira, kapena dzenje losindikizira la mesh limadzazidwa ndi tsitsi la pepala, chodabwitsa cha ufa, chotchedwa kutsekereza. Kuthetsa njira ndi: kuonjezera zili zosungunulira inki, kuchepetsa liwiro la inki kuyanika, ntchito mkulu pamwamba mphamvu pepala kusindikiza.

d) Kutayika kwa inki

Chochitika cha mawanga akuwonekera pagawo lamunda wa kusindikiza. Njira zochotsera zikuphatikizapo: kuwonjezera mafuta osakaniza a inki, kusintha maonekedwe a inki. Sinthani ngodya ya squeegee, yonjezerani liwiro losindikiza, ndikusintha mbale yosindikizira yakuya-cavity ndi mbale yosindikizira yakuya-cavity.

e) Kanda

Pali zizindikiro za squeegee pazosindikiza. Njira zochotsera ndizo: gwiritsani ntchito inki yoyera popanda zinthu zakunja zosakanikirana posindikiza. Sinthani mamasukidwe akayendedwe, kuuma ndi kumamatira kwa inki. Gwiritsani ntchito squeegee yapamwamba kwambiri, sinthani ngodya pakati pa squeegee ndi mbale yosindikizira.

Akatswiri opanga mapangidwe a OYANG adasanthula ndikukonza makinawo molingana ndi zovuta zingapo pakusindikiza, ndikupanga Honor Sereis ELS Rotog ravure Printing Machine kuti athetse zowawa za ogwiritsa ntchito ndi makampani.

Ubwino wa Rotogravure ndi kugwiritsa ntchito

Ndondomekoyi imapereka mwayi wotumiza inki mosasinthasintha, kudutsa kuchulukitsitsa kosiyanasiyana, komanso kuthamanga kwambiri, ndikupangitsa kuti ikhale yoyenera kwa mapulogalamu omwe amafunikira chithunzithunzi chapamwamba, monga kusindikiza, kulongedza, zolemba, kusindikiza chitetezo, ndi kusindikiza kokongoletsera.

Kukhazikika kwa masilinda osindikizira omwe amagwiritsidwa ntchito kumapangitsa kusindikiza kwa gravure kukhala njira yabwino yoperekera kusindikiza kwapamwamba kwambiri pamakina aatali kwambiri kapena obwerezabwereza, kumapereka phindu panjira zina.

ukadaulo wa OYANG ndi chidziwitso

Katswiri wochititsa chidwi, yemwe amayang'ana pakupanga phindu kwa makasitomala ake, zopangidwa kuchokera ku makina osindikizira a OYANG Rotogravure, M'zaka zitatu zokha makina osindikizira a OYANG Rotogravure adzipangira mbiri yabwino komanso dzina labwino ku China, ndipo pali mayiko ndi zigawo zambiri padziko lonse lapansi komwe mafakitale amakasitomala ali ndi makina athu osindikizira a Honor electronic shaft rotogravure, ndipo amathamanga kwambiri.

Katswiri wochita chidwi kwambiri, OYANG yakhazikitsa miyezo yatsopano pakusindikiza kwazithunzi zapaintaneti m'malo ovuta kwambiri monga ma CD osinthika ndi makina ake osindikizira a Honor® a rotogravure . Kupeza zotsatira zabwino kwambiri zosindikizira pamapaketi osunthika apamwamba kwambiri kumabweretsa zovuta zatsopano pakusindikiza kwa gravure, koma kupita patsogolo kwaukadaulo, kugwiritsa ntchito mosavuta, nthawi yosinthira mwachangu komanso kuchepetsedwa kuwononga makina osindikizira a OYANG kumawapangitsa kukhala chimodzi mwazosankha zapamwamba kwambiri kwa makasitomala ku China komanso padziko lonse lapansi.
