Sublimation luam ntawv siv nyob rau hauv kev tshaj tawm, luam ntawv duab thiab rau kev tsim khoom lag luam khoom dab tsi. Cov txiaj ntsig cov duab pom tseeb, nws muaj peev xwm kos cov lus me me tshaj plaws.
Sublimation luam ntawv yog ib txoj kev rau dyeing lub teeb hluavtaws cov ntaub ntawv. Ua tsaug rau nws, cov xim muaj xim ci, tiv taus ntau yam cawv. Cov txheej txheem hais txog cov qauv digital ntawm kev hloov duab.
Tus tsim ntawm sublimation luam tawm yog tus Fabkis hom Noel de Plassé. Xyoo 1957, nws tau pom tias qee qhov dyes tuaj yeem hla los ntawm ib lub xeev mus rau lwm qhov, dhau ntawm cov qib theem pib. Qhov no tshwm sim ntawm kub ntawm 190 degrees.
Tshuab
Nws yog ua raws tus txheej txheem thaum cov khoom tau dhau los ntawm lub xeev khov mus rau kua, dhau ntawm lub xeev cov roj. Lub zas xim pauv hauv lub xeev rhaub rau daim ntawv thermal. Thaum ua haujlwm nrog lub tshuab luam ntawv thermal, tus number case evaporates, thiab daim duab yog thov los ntawm daim kab xev nyob nruab nrab ntawm daim ntawv thermal thiab cov cua kub ntawm lub cuab yeej.
Sublimation luam ntawv zoo ib yam li inkjet luam ntawv hauv cov khoom, tab sis txawv hauv uas txhua daim ntawv tau tshwm rau ntawm qhov chaw thov. Vim qhov no, cov duab lossis cov ntawv sau yuav tsum muaj tseeb thiab ruaj khov.
Txoj kev luam ntawv yuav ua nyob rau hauv peb theem. Cov xim tsis tau thov txhua lub sijhawm. Hauv qee cov txuj ci tshiab tsis ntev los no, ib qho ntxiv plaub txheej txheej tseem raug siv. Qhov no tshwm sim ntau dua thaum luam tawm duab thiab ua haujlwm nrog cov chaw nyuaj, uas tuaj yeem nce kev tiv thaiv cov duab los ntawm kev sib kis ncaj qha los ntawm ultraviolet rays.
Dye sublimation tso cai rau koj kom tau txais cov duab zoo. Koj tsis tuaj yeem ntshai tias qhov tsis zoo ntawd xws li banding lossis solubility yuav tshwm sim. Vim tias tsis muaj qhov tso tawm hauv cov duab, tsis muaj ciam teb ntawm thaj chaw huv thiab qhov xim dawb.
Qhov zoo thiab qhov tsis zoo
Ib qho ntawm qhov zoo yog qhov muaj peev xwm los ua kom zoo ntsuas kub. Ua tsaug rau qhov no, qhov yuav tsum tau qhia meej thiab zoo ib yam ntawm daim duab tau raug kho, thiab halftones raug tso tawm kom pom.
Qhov zoo muaj:
- yooj yim ntawm sublimation luam ntawv;
- kho kom zoo nkauj ib qho khoom lag luam;
- daim duab siab zoo;
- lub peev xwm los tsim cov duab kos ntawm txhua qhov nyuaj.
Cov haujlwm tsis siv sijhawm ntau. vim muaj tshuaj lom neeg muaj pes tsawg leeg xim tsev thiab ntsuas kub rau lub sijhawm luam ntawv, lub neej ua haujlwm lossis khaws khoom ntawm cov khoom ua tiav los ntawm hom no nce.
Qhov tsis zoo suav nrog tus nqi siab ntawm cov neeg siv tau thiab cov cuab yeej siv lawv tus kheej. Cov tom kawg muaj feem ntau siv cov tshuab luam ntawv, cov tuam txhab luam ntawv. Kev siv cov cuab yeej txiav txim siab tsim nyog rau cov lag luam me thiab nruab nrab. Lwm qhov tsis zoo yog qhov yuav tsum ua raws li qee qhov huab cua nyob sab hauv tsev thaum ua haujlwm. Tsis tas li ntawd, cov duab siab zoo tau ua tiav tshwj xeeb thaum siv lub teeb nrig thim rov qab.
Hom kev sublimation luam ntawv
Nws muaj ob lub ntsiab:
- ncaj;
- tsis ncaj
Hauv thawj kis, xim pleev xim rau cov khoom sib xyaw nrog sab hauv, cov duab kos yog siv rau cov khoom tiav. Feem ntau, txoj kev ncaj qha yog siv los thov tus duab rau ntaub. Nws yog qhov zoo los ua chij thiab ntaub thaiv nyob rau hauv txoj kev no.
Kev luam tawm ncaj qha yog faib raws li ntub thiab qhuav. Thaum ntub, qhov chaw ua haujlwm yog kho nrog polyester primer. Daim duab yog tau thov siv lub tshuab luam ntawv. Cov tshuab no yog nrov rau kev ua haujlwm loj loj. Txoj kev qhuav yog kev siv ntawv thiab lub tshuab luam ntawv laser.
Indirect yog hu ua kev hloov chaw thermal. Cov thev naus laus zis muaj ob ntu. Ua ntej, daim iav duab yog luam tawm ntawm daim ntawv siliconized rau sublimation, tom qab ntawd cov duab tau hloov pauv siv lub cua sov nias thiab tus number case tshwj xeeb. Hom qauv no tau ua los ntawm inkjet, laser, offset thiab npo luam ntawv.
Cov tau thiab cov khoom siv siv
Keeb xeeb, sublimation luam ntawv tau thov rau cov ntaub hluavtaws. Thaum rhuab, cov khoom siv "qhib pores". Txij ntawm no, nws yooj yim siv pleev xim. Nws zoo nkaus li yuav tsum tau fused rau hauv ntaub, cia koj tau txais ib daim duab ruaj khov heev. Cov ntaub ntawv ntuj tsis muaj cov cuab yeej zoo li no, yog li, rau kev ua haujlwm zoo, lub cev muaj pes tsawg leeg yuav tsum muaj tsawg kawg yog 50% ntawm chemistry. Qhov kev xaiv zoo tshaj plaws rau T-shirts yog ob-txheej npuag muaj nrog txheej ntawm polyamide thiab paj rwb.
Lub thev naus laus zis tso cai rau koj hloov cov xim rau txhua qhov chaw:
- ntoo;
- yas;
- iav;
- ceramic;
- hlau.
Txij li cov xim sublimation sib cuam tshuam tshwj xeeb nrog cov polymer sib txuas, cov kua roj vanish tshwj xeeb yog thov rau cov khoom siv ua ntej ua ntawv thov. Cov ntawv luam tawm ua tau zoo tshaj yog tau txais ntawm cov ntawv ua los ntawm polyester lossis polyester.
Cov tau txais daim ntawv thov
Feem ntau, txoj kev yog siv rau kev tshaj tawm lossis kho kom zoo nkauj ntawm cov khoom lag luam kom nco qab. Tus nqa tau tuaj yeem yog:
- cov khoom ntawm cov khaub ncaws;
- pam vov pam vov;
- mugs;
- paib;
- cov ntawv twv txiaj;
- cov ntawv tshaj xo;
- fwj thiab ntau dua.
Rau kev tshaj tawm cov ntawv, cov ntawv tshwj xeeb thiab cov ntawv luam tawm loj tau siv, uas ua rau nws muaj peev xwm tau txais cov ntawv luam tawm uas muaj txiaj ntsig zoo.
Yuav ua li cas xaiv cov khoom siv rau cov duab ua haujlwm siab
Sublimation tshuab luam ntawv yog yooj yim heev uas nws tuaj yeem siv tau tom tsev. Muaj kev txawj ntse ntawm kev ua haujlwm nrog cov haujlwm tshwj xeeb, koj tuaj yeem thov daim duab rau T-shirts lossis mugs. Txawm li cas los xij, koj yuav tsum tau npaj kom txhij rau qhov tseeb tias lub tshuab luam ntawv muaj qhov pom zoo hauv qhov loj me. Tshwj xeeb cov uas ua haujlwm nrog ntaub. Thaum xaiv lub tshuab luam ntawv, xim them rau peb qhov:
- daim duab yam;
- kev kwv yees ncig ntawm cov khoom;
- hom thiab qhov loj ntawm cov khoom siv txheej txheem.
Qhov hloov ntawm daim duab mus rau cov khoom nruab nrab yog ua nyob rau hauv txhua txoj kev yooj yim uas tsis cuam tshuam nrog cua sov. Vim tias qhov no, lub tshuab luam ntawv thermal inkjet tsis siv.
Cov txiaj ntsig tshwm sim yog hloov pauv siv kub xovxwm. Koj tuaj yeem yuav cov twj siv nrog cov khoom me me lossis calender clamp. Xaiv yog nyob ntawm ntau npaum li cas siv lub tshuab. Rau cov ntawv loj-cov ntawv tshaj tawm, calender heat presses siv.
Xim yog tseem them rau txoj kev xaiv raug kua mem. Yuav kom tau txais cov khoom lag luam zoo, koj yuav xav tau tus kheej xim profile. Ua li no, thaum yuav khoom, cov kws tshaj lij tau paub txog lub tshuab luam ntawv twg thiab nrog cov ntaub ntawv dab tsi koj yuav ua haujlwm.
Yog li, sublimation luam ntawv yog thev naus laus zis tshiab. Nws cov koob meej tau nce zuj zus, xws li yog daim teb ntawm daim ntawv thov. Hauv khw muag khoom, koj tuaj yeem yuav ntau yam tshuab luam ntawv uas txawv los ntawm lawv cov versatility lossis tsom qhov nqaim.
