Chiyambi: Chifukwa cha kusintha kosalekeza kwa malingaliro a ogula pakugwiritsa ntchito zinthu, zinthu zopangidwa mwamakonda zikukhala zodziwika kwambiri pakati pa ogula. Ukadaulo wosamutsa madzi umadutsa malire osafanana omwe sangasindikizidwe ndi kusindikiza kwathyathyathya. Pambuyo pa kusindikiza kosamutsa madzi, chinthucho chimakhala ndi kuyerekezera kwakukulu, ndipo kuwonjezera kwa chinthucho kwawirikiza kawiri, ndipo kusindikiza kosamutsa komwe kumapangidwa mwamakonda kumakwaniritsa zosowa za ogula masiku ano. Nkhaniyi yalembedwa ndiphukusi la utawaleza la Shanghai, ndipo ndikugawana nanu zinthu zingapo zomwe zimakhudza kusintha kwa mtundu wa silk screen.
Ukadaulo wosinthira madzi ndi mtundu wa kusindikiza komwe kumagwiritsa ntchito mphamvu ya madzi kuti kusungunule pepala/pulasitiki yosamutsa ndi mitundu yosiyanasiyana. Ubwino wake waukulu waukadaulo ndikuti sikufuna zida zapadera, sikuletsedwa ndi zolumikizira, sikufuna zinthu zapadera zogwiritsidwa ntchito, ndipo sikufuna kutentha kwambiri, bola ngati pali chida cholowetsa chithunzi (scanner kapena kamera ya digito), chida chojambulira (kompyuta), chida chotulutsa zithunzi (Inkjet printer), kuphatikiza inki yosamutsa madzi, pepala losamutsa madzi, mutha kusindikiza chithunzi chilichonse pa chinthu chilichonse cholimba komanso pamalo aliwonse opindika.
Kusamutsa chizindikiro cha madzi
Kusamutsa chizindikiro cha madzi ndi njira yosamutsira kwathunthu zithunzi ndi zolemba pa pepala losamutsira pamwamba pa substrate. Ndi yofanana kwambiri ndi njira yosamutsira kutentha, kupatula kuti kupanikizika kwa kusamutsa kumadalira kuthamanga kwa madzi. Ndi ukadaulo wotchuka wosamutsa madzi posachedwapa. Dera laling'ono la chidziwitso cha zithunzi likhoza kusamutsidwa pamwamba pa substrate, lomwe ndi lofanana ndi momwe njira yosindikizira pad imagwirira ntchito, koma ndalama zomwe zimayikidwa ndizotsika, njira yopangira ndi yosavuta, ndipo ndi yotchuka kwambiri ndi ogwiritsa ntchito. Njira yosamutsira chizindikiro cha madzi sikufuna kuyatsidwa ndi choyambitsa, imapewa kuipitsa zinthu zachilengedwe, ndipo ili ndi ubwino woonekeratu popanga ntchito zamanja ndi zokongoletsera.

Kusamutsa chophimba cha madzi
Chomwe chimatchedwa kusamutsa chophimba cha madzi ndikukongoletsa pamwamba pa chinthu chonsecho, kuphimba nkhope yoyambirira ya workpiece, ndikutha kusindikiza mapangidwe pamwamba ponseponse (magawo atatu) a chinthucho. Ubwino wake ndi uwu; koma vuto lake ndi lodziwikiratu, ndiko kuti, kusinthasintha. Pamene chonyamulira zithunzi chikukhudzana kwathunthu ndi substrate, n'kosapeweka kuti chidzatambasulidwa ndikuwonongeka. Chifukwa chake, kwenikweni, zimakhala zovuta kuti chithunzicho chisamutsidwe pamwamba pa chinthucho kuti chifike pamlingo wodalirika.
Zithunzi zambiri zosindikizidwa ndi zolemba za pepala losamutsira madzi zomwe zimagwiritsidwa ntchito kusamutsa zimapangidwa ndi utoto wa inki wokongoletsera komanso mawonekedwe osavuta obwerezabwereza, ndipo palibe chifukwa chogwiritsa ntchito filimu yopyapyala yowunikira kuwala posindikiza; mafilimu osamutsira madzi nthawi zambiri amapangidwa ndi zotambasuka. Amapangidwa ndi filimu yabwino yosungunuka m'madzi. Filimu yosamutsira yomwe imagwiritsidwa ntchito kusamutsa yamitundu itatu ndi yovuta kusamutsa ndikukopera zolemba zazing'ono komanso zithunzi zotsatizana.
02 Kusamutsa zinthu
Chigawo chosamutsira madzi
Chitsulo chosamutsira madzi chingakhale filimu ya pulasitiki kapena pepala losamutsira madzi. Zinthu zambiri zimakhala zovuta kusindikiza mwachindunji. Mutha kusindikiza zithunzi ndi zolemba pa chitsulo chosamutsira madzi kudzera muukadaulo wosindikiza wachikulire, kenako nkusamutsa zithunzizo ku chitsulo. Zipangizo.
1) Filimu yophimba madzi pamwamba yopindika mbali zitatu
Filimu yophimba madzi imasindikizidwa pamwamba pa filimu ya polyvinyl alcohol yosungunuka m'madzi pogwiritsa ntchito njira yosindikizira yachikhalidwe ya gravure. Ili ndi liwiro lalikulu kwambiri lotambasula ndipo ndi yosavuta kuphimba pamwamba pa chinthucho kuti ikwaniritse kusamutsa kwa magawo atatu. Choyipa chake ndichakuti pakuphimba, chifukwa cha kusinthasintha kwakukulu kwa substrate, zithunzi ndi zolemba zimakhala zosavuta kusokoneza. Pachifukwa ichi, zithunzi ndi zolemba nthawi zambiri zimapangidwa ngati mapangidwe opitilira, ngakhale kusamutsako kutakhala kolakwika, zotsatira zowonera sizingakhudzidwe. Nthawi yomweyo, filimu yophimba madzi ya gravure imagwiritsa ntchito inki yosamutsa madzi. Poyerekeza ndi inki yachikhalidwe, inki yosindikiza yosamutsa madzi imakhala ndi kukana bwino madzi, ndipo njira yowumitsa ndi kuuma kwa volatilization.
2) Pepala losamutsira chizindikiro cha madzi
Chida choyambira cha pepala losamutsira zizindikiro za madzi ndi pepala lapadera. Chida choyambira chiyenera kukhala ndi khalidwe lokhazikika, kukula kolondola, kusinthasintha kwamphamvu ku malo osindikizira, kuchuluka kochepa kwambiri, kosavata kupindika ndi kupotoza, kosavuta kusindikiza ndi kupaka utoto, ndipo guluu pamwamba pake ndi wokutidwa mofanana. Zinthu monga kuthamanga kwa madzi m'thupi mwachangu. Kapangidwe kake, palibe kusiyana kwakukulu pakati pa pepala losamutsira madzi ndi filimu yosamutsira zokutira madzi, koma njira yopangira ndi yosiyana kwambiri. Kawirikawiri, pepala losamutsira zizindikiro za madzi limagwiritsidwa ntchito kupanga zithunzi ndi zolemba zosamutsira pamwamba pa substrate pogwiritsa ntchito kusindikiza pazenera kapena kusindikiza kwa offset. Njira yotchuka kwambiri yopangira ndikugwiritsa ntchito makina osindikizira a inkjet kupanga pepala losamutsira zizindikiro za madzi. N'zosavuta kupanga zithunzi ndi zolemba zomwe mumakonda malinga ndi zomwe mumakonda.
Choyambitsa
Choyambitsa ndi chosungunulira chachilengedwe chomwe chimatha kusungunula ndikuwononga filimu ya polyvinyl alcohol, koma sichidzawononga gawo losindikizira zithunzi. Choyambitsa chikagwira ntchito pa gawo losindikizira zithunzi, chimatha kuyambitsa ndikuchilekanitsa ndi filimu ya polyvinyl alcohol. Chomwe chimamatira pamwamba pa gawo lapansi kuti chikwaniritse kuphimba kwa madzi.
chophimba
Popeza kuti gawo losindikizidwa la filimu yophimbidwa ndi madzi lili ndi kuuma kochepa ndipo limakanda mosavuta, ntchitoyo ikatha kusinthidwa iyenera kupopedwa ndi utoto wowonekera kuti itetezedwe, motero kukongoletsa bwino kudzakhala bwino. Kugwiritsa ntchito varnish wowonekera wa PV kapena varnish wowonekera wa UV kungapangitse kuti ikhale yosalala kapena yowoneka bwino.
