Mvura-yakavakirwa ingi printer fekitari vanotenda kuti pane kukwezvana pakati pemvura-yakavakirwa ingi uye substrates, uye ingi firimu inogona zvakasimba adsorbed pamusoro pemvura substrate. Pamapepa substrates, mvura-based inki inogona kupinda mukati mapeji avo uye kunamatira vachishandisa "anchoring effect"; kune ma substrates ane akatsetseka uye asina-absorbent nzvimbo, kunamatira kwemvura-based inki kunoenderana nehukama pakati pemvura-based inki uye substrate mamorekuru.

Mvura-based inki printer fekitari vanotenda kuti sezvo nguva yekuomesa inowedzera, kunamatira kwemvura-based inki zvishoma nezvishoma kunowedzera kune kukosha kukuru, asi ipapo kunamatira kunoderera zvishoma nezvishoma kusvika zero, panguva iyo iyo inki firimu pamusoro inotsvedza uye yakaoma uye inorasikirwa nekunamatira. Nokudaro, kudhindwa kwepamusoro kwepamusoro kunofanira kuitwa kana viscosity yakakwira, kureva, kana inki yemvura inenge yava kuda kuoma. Nekuda kwekuti inki yemvura inodzivirira mvura, inogona kusanganiswa nemvura isati yaoma, uye kana yaoma, haichanyungudika mumvura. Naizvozvo, usarega iyo inki-yakavakirwa mumvura yakaoma pane anilox roller kudzivirira kuvhara maburi einki eiyo anilox roller. Mukuwedzera, panguva yekudhinda, flexographic plate inofanira kugara yakanyoroveswa neingi kuti isavhare magirafu uye zvinyorwa pandiro yekudhinda mushure mekunge ingi yaoma.

Mvura-based inki printer fekitari inotenda kuti kudhindwa kweinki yemvura kwakakosha zvikuru uye kune simba pakudhinda uye kudhinda mhando, kunyanya kusanganisira zviratidzo zvekuita seviscosity, thixotropy, adhesion, uye pH kukosha.

Viscosity inoreva kugona kweinki fluid mamorekuru kukwezvana uye kukanganisa kufamba kwemamorekuru. Muchidhindo chekudhinda, viscosity ye-water-based inki ndiyo inodiwa mamiriro ekuchengetedza kushandiswa kwemazuva ose uye kuendeswa kweinki. Izvo zvinhu zvinokanganisa viscosity yemvura-based inki inonyanya kusanganisira zvinotevera zvinhu.

(1) Viscosity yebhainda. Kune ingi uchishandisa pigment imwechete, viscosity yebhainda yakakura uye viscosity yeinki zvakare yakakura.

(2) Saizi, zvirimo uye dispersibility ye pigment particles. Kune imwechete binder, kana chiyero che pigment chakafanana, iyo yakakura zvidimbu, iyo yakakura viscosity, uye zvinopesana. Izvo zviri nani iyo pigment kupararira, iyo idiki iyo viscosity yeinki, uye zvinopesana, iyo yakakura viscosity yeinki.

(3) Kuchinja kwe tembiricha. Kana tembiricha yakakwira, hukama hwemvura hwemamorekuru muinki hunowedzera uye viscosity inoderera; apo kutonhora kunoderera, kubatanidzwa kweinki mamorekuru kunowedzera uye viscosity inowedzera.

Vagadziri vekudhinda kweinki vanotenda kuti thixotropy yeinki ndiyo pfuma yeinki fluidity inoshanduka pasi pekuita kwesimba rekunze. Pamuchina wekudhinda, nekuda kwekuita kweinki roller, fluidity uye ductility yeinki inowedzera panguva yekuendesa, kusvikira simba rekunze ranyangarika mushure mekuendeswa kune rakadhindwa pepa, uye fluidity yayo uye ductility kuderera, uye ingi inoshanduka kubva kune yakaonda kusvika kune gobvu, nokudaro kuve nechokwadi chekururama uye kujekesa kwe embossing uye madotsi. Kana iyo inki ine yakanaka thixotropy, inobatsira kune yakatsetseka uye yunifomu kuchinjisa inki uye inovandudza nhanho yekuchinjisa inki.
