Flexo, sezvinoreva zita racho, iplate yekudhinda yeflexographic yakagadzirwa neresin nezvimwe zvinhu. Itekinoroji yekudhinda ye letterpress. Mutengo wekugadzira maplate wakaderera zvikuru pane weplate dzekudhinda dzesimbi dzakadai se intaglio copper plates. Nzira iyi yekudhinda yakakurudzirwa pakati pezana remakore rapfuura. Zvisinei, panguva iyoyo, tekinoroji yeinki inotsigira mvura yakanga isati yagadzirwa zvakanyanya, uye zvinodiwa zvekuchengetedza zvakatipoteredza zvakanga zvisina kunyanya kutarisirwa panguva iyoyo, saka kudhindwa kwezvinhu zvisinganyungudike hakuna kukurudzirwa.

Kunyangwe kudhinda kweflexographic negravure printing zvakafanana zviri kuitwa, zvese zviri kusunungura, kumonera, kutamisa inki, kuomesa, nezvimwewo, asi kuchine mutsauko mukuru pakati pezviviri izvi. Kare, inki dzegravure ne solvent-based dzine mhedzisiro yakajeka yekudhinda. Zviri nani pane flexographic printing, ikozvino nekuvandudzwa kukuru kweinki dzemvura, inki dzeUV nedzimwe tekinoroji dzeinki dzisingakuvadzi nharaunda, hunhu hweflexographic printing hwava kutanga kuoneka, uye hahuna kuderera pane gravure printing. Kazhinji, flexographic printing ine hunhu hunotevera:

1. Mutengo wakaderera

Mutengo wekugadzira mapurati wakaderera zvikuru pane wegravure, kunyanya kana uchidhinda muzvikamu zvidiki, musiyano wacho wakakura.

2. Shandisa inki shoma

Kudhinda kweflexographic kunoshandisa plate yeflexographic, uye inki inotamiswa kuburikidza neanilox roller, uye kushandiswa kweinki kunoderedzwa neinopfuura 20% zvichienzaniswa neplate yeintaglio.

3. Kumhanya kwekudhinda kuri kukurumidza uye kushanda zvakanaka kwakakwira

Muchina wekudhinda weflexographic une inki yemhando yepamusoro inobva mumvura unogona kusvika nekukurumidza kwemamita mazana mana paminiti, nepo kudhinda kwakajairika kwegravure kuchingosvika mamita zana nemakumi mashanu chete.

4. Zvine hushamwari kune zvakatipoteredza

Mukudhinda kweflexo, inki dzinobva mumvura, inki dzeUV nedzimwe inki dzinobva kunharaunda dzinoshandiswa, idzo dzinobva kunharaunda kupfuura inki dzinobva ku solvent dzinoshandiswa mu gravure. Hapana kana VOCS emission, uye inogona kushandiswa seyemhando yepamusoro.

Zvinhu zvekudhinda gravure

1. Mutengo mukuru wekugadzira ndiro

Kare kare, magravure plates aigadzirwa achishandisa nzira dzemakemikari dzekuora, asi mhedzisiro yacho yakanga isina kunaka. Iye zvino ma laser plates anogona kushandiswa, saka kunyatsorongeka kwacho kwakanyanya, uye ma printing plates akagadzirwa nemhangura nedzimwe simbi anogara kwenguva refu kupfuura ma flexible resin plates, asi mutengo wekugadzira ma plates wakakwirawo. Mari yekutanga yakakwira, yakakura.

2. Kunyatso dhinda uye kuenderana kuri nani

Pureti yesimbi yekudhinda inonyanya kukodzera kudhindwa kwehuwandu, uye ine kugadzikana kuri nani. Inokanganiswa nekuwedzera kwekupisa uye kudzikira uye idiki.

3. Inki inoshandiswa zvakanyanya uye mutengo wakakwira wekugadzira

Panyaya yekutumira inki, kudhinda gravure kunotora inki yakawanda, izvo zvinowedzera mari yekugadzira.
