Nyob rau hauv daim ntawv lo luam, daim ntawv reciprocating pub ib nrab-tig thiab tag nrho-tig offset printing khoom yog ib yam tshiab ntawm luam ntawv txoj kev, uas yog feem ntau siv nyob rau hauv ua ke luam, thiab yog tseem haum rau luv luv (ntev) version nyob rau hauv tib printing.
Nyob rau hauv txoj kev luam ntawv tam sim no siv rau daim ntawv lo luam, ntau hom kev luam ntawv xws li offset printing, gravure printing, flexo printing thiab silk screen printing. Kev muag khoom qis luam tawm yog lub zog tshiab tuaj rau ntawm lub khw luam ntawv, muab cov ntawv luam tawm cov ntawv luam tawm thiab lawv cov neeg muas zaub nrog ib txoj kev tshiab ntawm kev luam ntawv. Tsis zoo li flexo, nws muaj ntau dua zoo.
Zoo ntawm offset thiab flexo
Offset luam ntawv thiab luam theej luam tawm kuj tseem siv tau rau daim ntawv lo, tiam sis muaj lwm txoj hau kev, tab sis siv cov ntawv luam ntawm flexographic luam ntawv ntau dua hauv cov tshuab luam ntawv hom qis, offset luam ntawv muaj nws qhov zoo thiab qhov tsis zoo.
Cov ntaub ntawv npog npog npog npog cov txheej txheem yog ua thiab muaj ntau lub plhom ntawm cov lej rov qab uas ua kom ntev dua txoj kab. Cov ntawv xov xwm ntiag tug yog ib daim duab zoo, thaum lub flexo luam tawm yog duab tsis zoo. Offset luam ntawv yog siv ntau txoj kev luam tawm uas yog ib txoj kev luam tawm uas yog thawj zaug hloov cov duab ntawm cov ntawv tso nkag rau ib daim pam thiab mam li hloov mus rau ntawm cov ntawv luam tawm.
Cov phev siv hauv ob txoj kev luam tawm kuj tseem txawv. Tus cwj mem muab luam tawm nyob hauv flexo luam ntawv zoo ib yam li viscosity rau mis. Lub phaj yog ua los ntawm cov ntaub lis loos lossis cov yas thiab tus cwj mem ntawm lub phaj raug xa mus ncaj nraim rau hauv paus los yog ntawv cov ntawv lo. Offset inks muaj qhov sib txawv, hnyav thiab muaj lub zog tinting zog. Tus number case yog pauv mus rau lub phaj ua ntej thiab ces pauv mus rau lub substrate ntawm daim pam. Lub cwj pwm hloov kua mis ntau dua.
Lub siab tshaj plaws ntawm cov luam ntawv ntawm flexo luam tawm yog 170 ~ 180 dpi, thiab qhov muag offset printing tuaj yeem ncav cuag 200 ~ 300 dpi, thiab luam ntawv yog ib qho yooj yim thiab pheej yig dua. Offset luam tawm yuav tsum yog UV qhuav, thaum lub flexo printing tau qhuav nrog cua kub los yog UV.
Cov lej naj npawb cov nqi rau cov offset thiab flexo kuj txawv. Cov number case ntim ntawm lub flexo yog tswj los ntawm mesh ntim ntawm lub anilox yob, thaum lub offset yog kho los ntawm tus number case ciav yuam. Qhov sib txawv ntawm cov flexo thiab lub vas sab: lub sijhawm npaj ua ntej yuav zoo ib yam rau ob leeg. Ob qho tib si sau tau siab, siab li 100 txog 200 meters ib feeb twg. Cov lej siab tshaj ntawm ob qho tsis txawv, thiab muaj peev xwm ncav cuag li 1000 taw ntawm ib feeb.
Qhov zoo ntawm offset luam ntawv yog superior flexo printing, uas yog qhov kom zoo dua ntawm kev luam tawm uas feem ntau hais. Piv rau flexo luam tawm, offset muaj ntau dua ib nti thiab ib yam khoom siv kho qhov muag zoo dua. Qhov ntau ntawm cov duab ua luam tawm los ntawm cov ntawv luam tawm flexo feem ntau yog li 3% thiab 98%, thiab cov tub ntxhais kawm ntau tshaj ntawm cov offset yuav ncav cuag li 0 mus rau 100%. Yog ib qhov zoo tshaj plaws ntawm kev lag luam offset yog tias tus nqi ntawm qhov offset luam ntawv phaj yog qis dua tus nqi ntawm cov ntawv luam tawm flexo thiab lub khawm gravure ntawd cov nuj nqi ntawm kev ua haujlwm tshiab. Tib lub sij hawm, qhov offset sij hawm luam tawm yog luv dua tus flexo printing, uas yuav siv sij hawm nruab nrab 10 feeb. Qhov no txhais tau tias koj tuaj yeem sau cov hauj lwm tshiab sai sai.
Ua haujlwm yooj yim yog lwm qhov kom zoo dua. Txawm tias ib lub tshuab luam ntawv tau luam tawm tau sau zoo zoo rau kev tshaj tawm, tab sis nyob rau hauv flexographic thiab UV flexo luam ntawv, kev tu xyuas yuav tsum tau muab ua txhua yam kom tau. Tsis tas li ntawd, qhov ruaj ntseg ntawm offset luam ntawv yog siab, thiab nws yog qhov tsim nyog rau luam ntawv cov hauj lwm nrog loj printing ntim thiab ntev mus los.
Offset luam ntawv tau zoo sib xws rau xim luam. Qhov loj tshaj plaws ntawm kev nplua nuj luam tawm yog tias nws yog tib txoj kev luam tawm hauv lub ntiaj teb nrog ib qho qauv, uas muaj peev xwm ua tau tib yam xim zoo li cov qauv formula.
Ua kom muaj kev cov nyom
Tsis muaj kev luam ntawv zoo meej, thiab lub web offset luam tawm tsis muaj qhov kos. Qhov teeb meem tam sim no yog yuav ua li cas thiaj li txawj siv tshuab luam ntawv. Offset luam tawm txawv ntawm flexo printing. Nws yuav tsis yooj yim rau kev kawm, tab sis tom qab kawm tau zoo, tsis muaj qhov teeb meem daim ntawv thov. Flexo luam ntawv tuaj yeem siv rau cov ntaub ntawv uas tsis yog siv xws li films lossis stickers, uas yog kev sib tw rau kev luam ntawv. Tib lub sij hawm, nyob rau hauv lub ntsej muag ntawm ntau hom ntawv substrates, offset luam tawm tsuas yog poob siab.
Peb pom tau tias qhov offset luam tawm muaj cov kev tsis txaus siab nram no: cov kev cai rau cov neeg ua haujlwm luam ntawv tau siab dua; vim hais tias cov qauv tsim ntawm lub tshuab luam ntawv offset yog qhov nyuaj, cov peev ntawm cov cuab yeej yog siab dua; qhov pov tseg ntau dua; lub sij hawm npaj rau qhov kev sib tw yog ntev tshaj li ntawm cov ntawv luam tawm flexographic.
Feem ntau qhov loj ntawm lub vev xaib ntawm lub offset offset yog tsau, tab sis nws yuav daws tau siv lub luam tawm me me loj printing web offset, tab sis nws kim dua.
Dej offset VS dej tsis ua haujlwm
Tam sim no, muaj ob txoj kev luam tawm rau kev lag luam luam ntawv, ib qho dej luam tawm thiab lwm qhov dej tsis zoo. Nyob hauv txoj dej offset, dej tau pauv mus rau hauv cov ntawv xov xwm ntawm lub tshuab luam yeeb, thiab tus cwj mem tsis tuaj yeem koom nrog lub tsho ntawm cov ntawv luam ntawm vim muaj dej.
