Lub phaj flexographic yuav tsum tau ntxuav tam sim ntawd tom qab luam ntawv rau ntawm lub tshuab luam ntawv flexo, txwv tsis pub cov kua yuav qhuav ntawm qhov chaw ntawm lub phaj luam ntawv, uas nyuaj rau tshem tawm thiab yuav ua rau cov phaj tsis zoo. Rau cov kua uas muaj kuab tshuaj lossis UV inks, siv cov kuab tshuaj sib xyaw (xws li cawv) nrog qhov concentration qis dua uas phim lub phaj rau kev ntxuav. Rau cov kua uas muaj dej, nws tuaj yeem ntxuav nrog cov kua alkaline lossis cov tshuaj ntxuav qib siab rau kev luam ntawv flexographic. thiab tsis txhob siv txhuam tawv kom tiv thaiv kev khawb ntawm lub phaj luam ntawv. Tom qab ntxuav, ziab lub phaj luam ntawv nrog ib daim ntaub tsis muaj plaub, ceev faj tsis txhob txhuam lub phaj luam ntawv ntau zaus, thiab kaw nws rau kev siv tom qab ziab.
