Iindlela Zokushicilela
Itekhnoloji, kukho iindlela ezininzi zokuprinta, ezinje ngoshicilelo oluthe ngqo, ukukhuphela ukuprinta kunye nokuchasa ukuprinta.
Kushicilelo oluthe ngqo, ukuncamathisela kokushicilela kufuneka kulungiswe kuqala.Iipilisi, ezifana ne-alginate paste okanye i-starch paste, kufuneka zixutywe ngokulingana okufunekayo kunye nedayi kunye nezinye iikhemikhali eziyimfuneko ezifana ne-agent yokumanzisa kunye ne-fixing agents.Ezi ke ziprintwa kwilaphu lomhlaba elimhlophe ngokwendlela yoyilo olufunwayo.Kwimizila yokwenziwa, i-paste yokuprinta inokwenziwa ngee-pigments endaweni yedayi, emva koko intlama yokuprinta iya kubandakanya ii-pigments, i-adhesives, i-emulsion paste kunye nezinye iikhemikhali eziyimfuneko.
Ekushicileleni ukukhutshwa, ilaphu lomhlaba kufuneka liqale lidaywe ngombala womhlaba ofunekayo, emva koko umbala womhlaba ukhutshwe okanye uxutywe kwiindawo ezahlukeneyo ngokuprinta nge-paste yokukhupha ukuze ushiye izinto ezifunwayo.I-dischargepaste ngokuqhelekileyo yenziwe nge-agent yokunciphisa njenge-sodium sulphoxylate-formaldehyde.
Ukuchasa ukuprinta.izinto ezichasayo ukudaya kufuneka ziqale zisetyenziswe kwilaphu lomhlaba, emva koko ilaphu lidayiwe.Emva kokuba i-cloth idayiwe, ukuchasana kuya kususwa, kwaye iiplani zivela kwiindawo apho ukuchasana kuprintwe.
Kukho nezinye iintlobo zoshicilelo, umzekelo, ukuprintwa kwe-sublistatic kunye nomhlambi wokushicilela.Kwikona, uyilo luprintwa kuqala ephepheni emva koko iphepha elineziyilo licinezelwe ngokubhekiselele kwilaphu okanye iimpahla ezifana neeT-shirts.Xa ubushushu busetyenziswa, uyilo ludluliselwa kwilaphu okanye ingubo.Ekugqibeleni, izinto ezimfutshane zefibrous ziprintwa kwiipateni kwiilaphu ngoncedo lwe-adhesives.I-Electronstatic flocking idla ngokusetyenziswa.
Izixhobo Zokuprinta
Ukushicilela kunokwenziwa ngokuprintwa kwerola, ukuprintwa kwesikrini okanye, kutshanje, izixhobo zokuprinta inkjet.
1. Ushicilelo lweRoller
Umatshini wokuprinta we-roller ubandakanya isilinda esikhulu soxinzelelo esiphakathi (okanye esibizwa ngokuba sisitya soxinzelelo) esigqunywe ngerabha okanye iiplies ezininzi zelaphu elidityanisiweyo loboya-linen enika isilinda ngokugudileyo kunye noxinzelelo olulastiki umphezulu.Iirola ezininzi zobhedu ezikroliweyo kunye noyilo oluza kuprintwa zibekwe malunga ne-cylinder yoxinzelelo, i-roller enye yombala ngamnye, ngokudibana ne-cylinder yoxinzelelo.Njengoko zijikeleza, i-roller yokushicilela nganye ekroliweyo, eqhutywa kakuhle, iphinda iqhube i-roller yayo yefenisha, kwaye le yokugqibela ithwala intlama yokushicilela ukusuka kwibhokisi yayo yombala ukuya kwirola yokushicilela ekroliweyo.Intsimbi ebukhali ebizwa ngokuba yi-blade yokucoca ugqirha isusa intlama engaphezulu kwi-roller yokushicilela, kwaye enye i-blade ebizwa ngokuba yi-lint doctor blade ikhupha nayiphi na i-lint okanye ukungcola okubanjwe yi-roller yokushicilela.Ilaphu eliza kuprintwa lityiswa phakathi kweerola zokuprinta kunye ne-cylinder yoxinzelelo, kunye nelaphu elingwevu elixhasayo ukukhusela umphezulu we-cylinder ukuba ungangcoliswa ukuba intlama yombala ingena kwilaphu.
Ukuprintwa kwe-roller kunokubonelela ngemveliso ephezulu kakhulu kodwa ukulungiswa kwee-roller ezikroliweyo zokushicilela kuyabiza, nto leyo, ngokoqobo, yenza ukuba ifaneleke kuphela kwiimveliso ezide.Ngaphezu koko, ububanzi be-roller yokushicilela kunciphisa ubungakanani bepateni.
2. Ukuprintwa kweSkrini
Ukuprintwa kwesikrini, ngakolunye uhlangothi, kufanelekile kwii-odolo ezincinci, kwaye zilungele ngokukodwa ukuprinta amalaphu alula.Kushicilelo lwesikrini, izikrini zokuprinta ezinemesh ezilukiweyo kufuneka ziqale zilungiswe ngokoyilo oluza kuprintwa, omnye ngombala ngamnye.Kwisikrini, iindawo apho intlama yombala kufuneka ingene zidityaniswe ngefilim enganyibilikiyo ishiya indawo eshiyekileyo yesikrini ivulekile ukuvumela incama yokuprinta ukuba ingene kuzo.Ushicilelo lwenziwa ngokunyanzela intlama yoshicilelo efanelekileyo ngepatheni yomnatha kwilaphu elingaphantsi.Isikrini silungiswa ngokugquma isikrini ngefotogelatin kuqala kwaye sibeke umfanekiso ongalunganga woyilo kuwo kwaye emva koko siwuveze ekukhanyeni okulungisa kunye nokugquma ifilimu enganyibilikiyo kwiscreen.I-coating ihlanjwa ukusuka kwezo ndawo apho i-coating inganyangwanga, ishiya i-interstices ekwisikrini ivuliwe.Ushicilelo lwescreen semveli lushicilelo lwescreen esisicaba, kodwa ukuprintwa kwescreen esijikelezayo kukwadume kakhulu kwimveliso enkulu.
3. Ushicilelo lwe-Inkjet
Kunokubonwa ukuba mhlawumbi kushicilelo lwerola okanye ushicilelo lwesikrini ukulungiswa kudla ixesha nemali nangona iinkqubo zeComputer Aided Design ( CAD ) ziye zasetyenziswa ngokubanzi kwimizi-mveliso emininzi yokushicilela ukuncedisa kulungiselelo loyilo.Uyilo oluza kushicilelwa kufuneka luhlalutywe ukugqiba ukuba yeyiphi imibala enokuthi ibandakanyeke, emva koko iipateni ezingalunganga zilungiselelwe umbala ngamnye kwaye zidluliselwe kwiirola zokuprinta okanye izikrini.Ngexesha lokuprintwa kwesikrini kwimveliso yobuninzi, i-rotary okanye i-flat, izikrini kufuneka zitshintshwe kwaye zicocwe rhoqo, nto leyo ichitha ixesha kunye nomsebenzi.
Ukuze kuhlangatyezwane nemfuno yemarike yanamhlanje yokusabela ngokukhawuleza kunye neesayizi ezincinci zebhetshi ye-inkjet yoshicilelo lwetekhnoloji iya isetyenziswa kakhulu.
Ushicilelo lwe-Inkjet kwiilaphu zisebenzisa itekhnoloji efanayo naleyo isetyenziswa kushicilelo lwephepha.Ulwazi lwedijithali loyilo oludalwe kusetyenziswa inkqubo ye-CAD lunokuthunyelwa kumshicileli we-inkjet (okanye ngokuqhelekileyo ubizwa ngokuba ngumshicileli we-inkjet yedijithali, kunye neempahla eziprintiweyo zingabizwa ngokuba yi-textiles yedijithali ) ngokuthe ngqo kwaye iprintwe kwiilaphu.Xa kuthelekiswa nobuchwepheshe boshicilelo lwemveli, inkqubo ilula kwaye ixesha elincinci kunye nobuchule obufunekayo njengoko inkqubo izenzekelayo.Ngaphezu koko, kuya kuncitshiswa ungcoliseko.
Ngokubanzi, kukho imigaqo emibini esisiseko yoshicilelo lwe-inkjet yamalaphu.Enye yi-Continuous Ink Jetting ( CIJ ) kwaye enye ibizwa ngokuba yi "Drop on Demand" (DOD).Kwimeko yangaphambili, uxinzelelo oluphezulu kakhulu ( malunga ne-300 kPa ) olwakhiwe ngempompo yonikezelo lwe-inki inyanzela i-inki ngokuqhubekayo ukuya emlonyeni, ububanzi bayo buhlala malunga ne-10 ukuya kwi-100 ye-micrometres.Phantsi kokungcangcazela okuphezulu okubangelwa yi-peizoelectric vibrator, i-inki iye yophuka ibe ngumsinga wamathontsi ize ikhutshwe embhobho ngesantya esiphezulu kakhulu.Ngokoyilo, ikhompyutha iya kuthumela imiqondiso kwi-electrode yokutshaja etshaja ngombane amathontsi e-inki akhethiweyo.Xa udlula kwi-electrode ejikwayo, amathontsi angatshajwanga aya kuthi ngqo kwi-gutter yokuqokelela ngelixa amathontsi e-inki etshajiweyo aya kuphambukiswa kwilaphu ukwenza inxalenye yepateni eprintiweyo.
Kwindlela " yokwehla kwemfuno ", amathontsi e-inki anikezelwa njengoko efuneka.Oku kunokwenziwa ngokusebenzisa indlela yokudlulisa i-electromechnical.Ngokweepateni eziza kushicilelwa, ikhomputha ithumela imiqondiso ye-pulsed kwisixhobo se-piezoelectric esithi sona sitshintshe kwaye sivelise uxinzelelo kwigumbi le-inki ngokusebenzisa imathiriyeli eguqukayo ephakathi.Uxinzelelo lubangela ukuba amathontsi e-inki akhutshwe emlonyeni.Enye indlela eqhelekileyo esetyenziswa kubuchule be-DOD kukusebenzisa indlela yombane yobushushu.Ekuphenduleni imiqondiso yekhompyutha iheater ivelisa amaqamza kwigumbi le-inki, kwaye amandla okwandisa amaqamza akhupha amathontsi e-inki ukuba akhutshwe.
Ubuchwephesha be-DOD bunexabiso eliphantsi kodwa isantya soshicilelo sikwangaphantsi kuneso sobuchule be-CIJ.Ekubeni amathontsi e-inki ekhutshwa ngokuqhubekayo, iingxaki zokuvala umlomo aziyi kwenzeka phantsi kobuchule be-CIJ.
Abashicileli be-Inkjet bakholisa ukusebenzisa indibaniselwano yemibala emine, oko kukuthi, cyan, magenta, yellow and black (CMYK), ukuprinta uyilo olunemibala eyahlukeneyo, kwaye ke iintloko zoshicilelo ezine kufuneka zidityaniswe, enye kumbala ngamnye.Nangona kunjalo abanye abashicileli baxhotyiswe ngeentloko zoshicilelo ezi-2*8 ukuze ithiyori ukuya kuthi ga kwi-16 imibala ye-inki inokuprintwa.Isisombululo sokuprinta sabashicileli be-inkjet sinokufikelela kwi-720 * 720 dpi.Amalaphu anokuprintwa ngeeprinta ze-inkjet ukusuka kwiintsinga zendalo, ezinjengomqhaphu, isilika kunye noboya, ukuya kwiintsinga zokwenziwa, ezifana ne-polyester kunye ne-polyamide, ngoko ke zininzi iintlobo zeenki ezifunekayo ukuhlangabezana nemfuno.Ezi ziquka ii-inks ezisebenzayo, ii-inks zeasidi, ii-inks zokusasaza kunye nee-inks ezinemibala.
Ukongeza kumalaphu okushicilela, iiprinta ze-inkjet zingasetyenziselwa ukuprinta i-T-shirt, i-sweatshirts, i-polo shirts, ukunxiba kwabantwana, iifaskoti kunye neetawuli.
