Flexo, raws li lub npe qhia, yog ib daim ntawv luam ntawv flexographic ua los ntawm cov resin thiab lwm yam khoom siv. Nws yog ib qho thev naus laus zis luam ntawv letterpress. Tus nqi ntawm kev ua phaj qis dua li cov ntawv luam ntawv hlau xws li cov phaj tooj liab intaglio. Txoj kev luam ntawv no tau raug pom zoo rau nruab nrab ntawm lub xyoo pua dhau los. Txawm li cas los xij, thaum lub sijhawm ntawd, cov thev naus laus zis txhawb nqa dej-raws li tsis tau tsim kho ntau, thiab cov kev cai rau kev tiv thaiv ib puag ncig tsis tau txhawj xeeb heev rau lub sijhawm ntawd, yog li kev luam ntawv ntawm cov khoom tsis nqus dej tsis tau txhawb nqa.

Txawm hais tias kev luam ntawv flexographic thiab kev luam ntawv gravure yeej zoo ib yam hauv cov txheej txheem, lawv ob leeg yog unwinding, winding, hloov number case, ziab, thiab lwm yam, tab sis tseem muaj qhov sib txawv loj hauv cov ntsiab lus ntawm ob qho. Yav dhau los, gravure thiab cov kuab tshuaj inks muaj cov teebmeem luam ntawv pom tseeb. Zoo dua li kev luam ntawv flexographic, tam sim no nrog kev txhim kho zoo ntawm cov number case dej, UV number case thiab lwm yam thev naus laus zis zoo rau ib puag ncig, cov yam ntxwv ntawm kev luam ntawv flexographic pib tshwm sim, thiab lawv tsis qis dua kev luam ntawv gravure. Feem ntau, kev luam ntawv flexographic muaj cov yam ntxwv hauv qab no:

1. Tus nqi qis dua

Tus nqi ntawm kev ua phaj yog qis dua li ntawm gravure, tshwj xeeb tshaj yog thaum luam tawm hauv cov khoom me me, qhov sib txawv loj heev.

2. Siv cov kua mem tsawg dua

Cov ntawv luam ntawv flexographic siv lub phaj flexographic, thiab cov kua mem raug xa mus rau hauv lub anilox roller, thiab kev siv kua mem raug txo ntau dua 20% piv rau lub phaj intaglio.

3. Qhov ceev ntawm kev luam ntawv yog ceev thiab qhov ua tau zoo dua

Lub tshuab luam ntawv flexographic nrog cov kua dej zoo tuaj yeem ncav cuag qhov ceev siab ntawm 400 meters ib feeb, thaum lub tshuab luam ntawv gravure feem ntau tsuas yog ncav cuag 150 meters.

4. Zoo dua rau ib puag ncig

Hauv kev luam ntawv flexo, feem ntau siv cov kua mem dej, cov kua mem UV thiab lwm cov kua mem uas tsis ua rau ib puag ncig puas tsuaj, uas zoo rau ib puag ncig dua li cov kua mem uas siv rau hauv gravure. Yuav luag tsis muaj VOCS emission, thiab nws tuaj yeem yog qib zaub mov.

Cov yam ntxwv ntawm gravure luam ntawv

1. Tus nqi siab ntawm kev ua phaj

Thaum ub, cov phaj gravure tau ua los ntawm kev siv cov tshuaj lom neeg xeb, tab sis qhov cuam tshuam tsis zoo. Tam sim no cov phaj laser tuaj yeem siv tau, yog li qhov tseeb siab dua, thiab cov phaj luam ntawv ua los ntawm tooj liab thiab lwm yam hlau ruaj khov dua li cov phaj resin yooj ywm, tab sis tus nqi ntawm kev ua phaj kuj siab dua. Siab, kev nqis peev pib ntau dua.

2. Kev luam ntawv zoo dua thiab kev sib xws

Lub phaj luam ntawv hlau zoo dua rau kev luam ntawv loj, thiab muaj kev sib xws zoo dua. Nws raug cuam tshuam los ntawm kev nthuav dav thiab kev cog lus thermal thiab me me.

3. Kev siv number case loj thiab tus nqi tsim khoom siab

Hais txog kev hloov pauv number case, gravure printing siv ntau number case, uas yuav luag ua rau cov nqi tsim khoom nce ntxiv.
