Njira Zosindikizira
Mwaukadaulo, pali njira zingapo zosindikizira, monga kusindikiza mwachindunji, kutulutsa kusindikiza komanso kukana kusindikiza.
Pakusindikiza mwachindunji, phala losindikiza liyenera kukonzedwa kaye.Mafuta, monga phala la alginate kapena phala la wowuma, amayenera kusakanizidwa mu gawo lofunikira ndi utoto ndi mankhwala ena ofunikira monga chonyowetsa ndi zokonzera.Izi zimasindikizidwa pa nsalu zoyera pansi molingana ndi mapangidwe omwe akufuna.Kwa nsalu zopangira, phala losindikizira likhoza kupangidwa ndi inki m'malo mwa utoto, ndiyeno phala losindikizira limakhala ndi inki, zomatira, phala la emulsion ndi mankhwala ena ofunikira.
Pakusindikiza kutulutsa, nsalu yapansi iyenera kupakidwa utoto ndi mtundu womwe mukufuna, kenako mtundu wapansi umatulutsidwa kapena kutsukidwa m'malo osiyanasiyana posindikiza ndi phala lotulutsa kuti musiye mapangidwe omwe mukufuna.The dischargepaste nthawi zambiri amapangidwa ndi kuchepetsa wothandizira monga sodium sulphoxylate-formaldehyde.
Mukukana kusindikiza.zinthu zomwe zimakana kudaya ziyenera kuyikidwa kaye pansalu yapansi, ndiyeno nsaluyo imapakidwa utoto.Pambuyo pa utoto wa nsalu, kutsutsa kudzachotsedwa, ndipo zojambulazo zimawonekera m'madera omwe kutsutsa kunasindikizidwa.
Palinso mitundu ina yosindikizira, mwachitsanzo, kusindikiza kwa sublistatic ndi kusindikiza kwamagulu.Pakona, mapangidwewo amayamba kusindikizidwa pamapepala ndipo kenaka pepala lokhala ndi mapangidwe amakanizidwa ndi nsalu kapena zovala monga T-shirts.Pamene kutentha kumagwiritsidwa ntchito, zojambulazo zimasamutsidwa pa nsalu kapena chovala.Pamapeto pake, zida zamtundu waufupi zimasindikizidwa pamapangidwe pansalu mothandizidwa ndi zomatira.Electronstatic flocking imagwiritsidwa ntchito kwambiri.
Zida Zosindikizira
Kusindikiza kungachitidwe ndi makina osindikizira, kusindikiza pazithunzi kapena, posachedwa, zida zosindikizira za inkjet.
1. Kusindikiza kwa Roller
Makina osindikizira odzigudubuza nthawi zambiri amakhala ndi silinda yayikulu yapakati (kapena yotchedwa pressure mbale) yomwe imakutidwa ndi mphira kapena zingwe zingapo za nsalu zophatikizika zaubweya zomwe zimapangitsa kuti silindayo ikhale yosalala komanso yosalala.Zodzigudubuza zingapo zamkuwa zojambulidwa ndi mapangidwe kuti zisindikizidwe zimayikidwa mozungulira cylinder yamphamvu, chogudubuza chimodzi pamtundu uliwonse, pokhudzana ndi silinda yamphamvu.Akamazungulira, zodzigudubuza zilizonse zojambulidwa, zoyendetsedwa bwino, zimayendetsanso chogudubuza chake cha furnisher, ndipo chomalizacho chimanyamula phala losindikizira kuchokera m'bokosi lamitundu kupita ku chopukusira chojambulidwa.Tsamba lakuthwa lachitsulo lotchedwa tsamba la dokotala woyeretsa limachotsa phala lochulukirapo kuchokera pa chogudubuza chosindikizira, ndipo tsamba lina lotchedwa lint doctor blade limachotsa nsalu iliyonse kapena dothi lomwe lagwidwa ndi chosindikizira.Nsalu yosindikizidwa imadyetsedwa pakati pa zodzigudubuza zosindikizira ndi cylinder yokakamiza, pamodzi ndi nsalu yofiira yofiira kuti zisawonongeke pamwamba pa silinda ngati phala lopaka utoto likulowa mu nsalu.
Kusindikiza kwa roller kungapereke zokolola zapamwamba kwambiri koma kukonzekera kwa odzigudubuza olembedwa ndi okwera mtengo, omwe, makamaka, amawapangitsa kukhala oyenera kupanga nthawi yayitali.Kuphatikiza apo, kukula kwa chogudubuza chosindikizira kumachepetsa kukula kwake.
2. Screen Printing
Kusindikiza pazenera, kumbali ina, kuli koyenera kwa maulamuliro ang'onoang'ono, ndipo makamaka oyenera kusindikiza nsalu zotambasula.Posindikiza pazithunzi, zosindikizira za mesh zolukidwa ziyenera kukonzedwa poyamba molingana ndi mapangidwe oti asindikizidwe, chimodzi pamtundu uliwonse.Pa zenera, madera omwe phala lopaka utoto siliyenera kulowa amakutidwa ndi filimu yosasungunuka ndikusiya zotsalazo zili zotseguka kuti phala losindikizidwa lilowemo.Kusindikiza kumapangidwa pokakamiza phala loyenera losindikizira kudzera pamtundu wa mauna pansalu yomwe ili pansi.Chophimbacho chimakonzedwa ndikuphimba chinsalucho ndi photogelatin poyamba ndikuyika chithunzi choyipa cha kapangidwe kake ndikuchiwonetsa kuti chikhale chowala chomwe chimakonza ndikuyika filimu yosasungunuka pazenera.Chophimbacho chimatsukidwa kuchokera kumadera omwe kupaka sikunachiritsidwe, ndikusiya ma interstices pawindo lotseguka.Kusindikiza kwachikale ndi kusindikiza pazenera, koma kusindikiza pazithunzi zozungulira kumakhalanso kotchuka kwambiri pakupanga kwakukulu.
3. Kusindikiza kwa Inkjet
Kungawonedwe kuti kaya pa makina osindikizira odzigudubuza kapena kusindikiza pazithunzi kukonzekera kumadya nthaŵi ndi ndalama ngakhale kuti makina a Computer Aided Design (CAD) akhala akugwiritsidwa ntchito mofala m’mafakitale ambiri osindikizira kuti athandize pokonzekera kamangidwe.Mapangidwe oti asindikizidwe ayenera kufufuzidwa kuti awone mitundu yomwe ingaphatikizidwe, ndiyeno mawonekedwe olakwika amakonzedwa pamtundu uliwonse ndikusamutsidwa ku zodzigudubuza kapena zowonera.Panthawi yosindikizira pazenera, zozungulira kapena zosalala, zowonetsera ziyenera kusinthidwa ndikutsukidwa pafupipafupi, zomwe zimawononganso nthawi komanso ntchito.
Kuti akwaniritse kufunika kwa msika wamasiku ano kuti ayankhe mwachangu komanso ukadaulo wosindikizira wa inkjet wamagulu ang'onoang'ono ukugwiritsidwa ntchito kwambiri.
Kusindikiza kwa inkjet pa nsalu kumagwiritsa ntchito ukadaulo wofanana ndi womwe umagwiritsidwa ntchito posindikiza mapepala.Zidziwitso za digito zamapangidwe opangidwa pogwiritsa ntchito makina a CAD zitha kutumizidwa ku chosindikizira cha inkjet (kapena chomwe chimatchedwa chosindikizira cha digito cha inkjet, ndipo nsalu zosindikizidwa nazo zitha kutchedwa kuti nsalu za digito) mwachindunji ndikusindikizidwa pansalu.Poyerekeza ndi matekinoloje osindikizira achikhalidwe, njirayi ndi yosavuta komanso nthawi yocheperako komanso luso zimafunikira chifukwa njirayo imakhala yokha.Kuphatikiza apo, kuchepeka kwa kuipitsa kudzayamba.
Nthawi zambiri, pali mfundo ziwiri zofunika pakusindikiza kwa inkjet kwa nsalu.Imodzi ndi Continuous Ink Jetting ( CIJ ) ndipo ina imatchedwa "Drop on Demand" (DOD).M'mbuyomu, kuthamanga kwambiri (kuzungulira 300 kPa) komwe kumapangidwa kudzera pa mpope woperekera inki kumakakamiza inki mosalekeza kupita kumphuno, m'mimba mwake yomwe nthawi zambiri imakhala pafupifupi 10 mpaka 100 ma micrometres.Pansi pa kugwedezeka kwakukulu komwe kumachitika chifukwa cha vibrator ya peizoelectric, inkiyo imathyoledwa ndikutuluka m'malovu ndikutulutsidwa pamphuno pa liwiro lalikulu kwambiri.Malinga ndi mapangidwewo, kompyuta imatumiza ma siginecha ku ma elekitirodi opangira magetsi omwe amalipira madontho a inki osankhidwa.Mukadutsa maelekitirodi opotoka, madontho osatulutsidwa amapita molunjika m'ngalande yosonkhanitsira pomwe madontho a inki opakidwa amapatutsidwa pansalu kuti apange gawo lazosindikizidwa.
Mu njira ya " drop on demand ", madontho a inki amaperekedwa monga akufunikira.Izi zitha kuchitika kudzera mu njira ya electromechnical transfer.Malinga ndi machitidwe omwe asindikizidwe, kompyuta imatumiza ma sign a pulsed ku chipangizo cha piezoelectric chomwe chimafooketsa ndikutulutsa kukakamiza pachipinda cha inki kudzera muzinthu zosinthika.Kuthamanga kumapangitsa kuti madontho a inki atulutsidwe pamphuno.Njira ina yomwe imagwiritsidwa ntchito kwambiri muukadaulo wa DOD ndi kudzera munjira yamagetsi yamagetsi.Poyankha chizindikiro cha kompyuta chotenthetsera chimatulutsa thovu mu chipinda cha inki, ndipo mphamvu yokulirapo ya thovulo imapangitsa kuti madontho a inki atulutsidwe.
Njira ya DOD ndiyotsika mtengo koma liwiro losindikiza ndilotsikanso kuposa la CIJ.Popeza madontho a inki amatulutsidwa mosalekeza, zovuta zotsekera nozzle sizichitika pansi pa njira ya CIJ.
Osindikiza a inkjet nthawi zambiri amagwiritsa ntchito mitundu inayi, yomwe ndi cyan, magenta, yachikasu ndi yakuda ( CMYK ), kusindikiza zojambula zamitundu yosiyanasiyana, choncho mitu inayi yosindikizira iyenera kusonkhanitsidwa, imodzi pamtundu uliwonse.Komabe osindikiza ena ali ndi mitu yosindikiza ya 2 * 8 kotero kuti mwachidziwitso mpaka mitundu 16 ya inki ikhoza kusindikizidwa.Kusindikiza kwa osindikiza a inkjet kumatha kufika 720 * 720 dpi.Nsalu zomwe zimatha kusindikizidwa ndi osindikiza a inkjet zimachokera ku ulusi wachilengedwe, monga thonje, silika ndi ubweya, mpaka ulusi wopangira, monga poliyesitala ndi polyamide, chifukwa chake pali mitundu yambiri ya inki yomwe ikufunika kukwaniritsa zofunikira.Izi zikuphatikizapo ma inki, ma inki a asidi, inki zobalalitsa ngakhalenso inki zamtundu.
Kuphatikiza pa nsalu zosindikizira, makina osindikizira a inkjet angagwiritsidwenso ntchito kusindikiza T-shirt, sweatshirts, malaya a polo, kuvala kwa ana, ma apuloni ndi matawulo.
