Ifekthri yephrinta ye-inki esekelwe emanzini ikholelwa ukuthi kukhona ukukhangana phakathi kwe-inki esekelwe emanzini nama-substrates, futhi ifilimu ye-inki ingakhangiswa ngokuqinile ebusweni be-substrate. Ngama-substrates ephepha, uyinki osuselwe emanzini ungangena ezikhaleni zawo futhi unamathele usebenzisa "umphumela wokunamathisela"; kuma-substrates anezindawo ezibushelelezi nezingamundi, ukunamathela kukayinki osuselwe emanzini kuncike ekuhlobaneni phakathi kwe-inki esekelwe emanzini nama-molecule e-substrate.

Imboni yokuphrinta ye-inki esekelwe emanzini ikholelwa ukuthi njengoba isikhathi sokumisa sikhula, ukunamathela koyinki osekelwe emanzini kancane kancane kukhuphuka kube yinani elikhulu, kodwa ukunamathela kancane kancane kuyehla ku-zero, ngaleso sikhathi indawo yefilimu ye-inki ibushelelezi futhi yomile futhi ilahlekelwa ukunamathela. Ngakho-ke, ukuphrinta kwembondela efanelekile kufanele kwenziwe lapho i-viscosity iphezulu, okungukuthi, lapho uyinki osuselwe emanzini usuzoma. Ngenxa yokuthi uyinki osuselwe emanzini awukwazi ukumelana namanzi, ungaxutshwa namanzi ngaphambi kokoma, futhi uma usumile, awusakwazi ukuncibilika emanzini. Ngakho-ke, ungavumeli inki esekelwe emanzini yome kurola ye-anilox ukuze ugweme ukuvala izimbobo ze-inki ze-anilox roller. Ukwengeza, phakathi nenqubo yokunyathelisa, ipuleti le-flexographic kufanele lihlale limanziswe ngoyinki ukuze kugwenywe ukuvala ihluzo nombhalo epuleti lokuphrinta ngemva kokuba uyinki womile.

Imboni yokuphrinta eyinki esekelwe emanzini ikholelwa ukuthi ukuphrinta kukayinki osekelwe emanzini kubaluleke kakhulu futhi kunomthelela enqubweni yokuphrinta nekhwalithi yokunyathelisa, ikakhulukazi okuhlanganisa izinkomba zokusebenza ezifana ne-viscosity, i-thixotropy, i-adhesion, ne-pH value.

I-viscosity ibhekisela ekhonweni lama-athomu kayinki oketshezi ukuze adonse futhi avimbele ukunyakaza kwama-molecule. Enqubweni yokunyathelisa, i-viscosity ye-inki esekelwe emanzini iyisimo esidingekayo sokugcina ukudluliswa okujwayelekile nokudluliselwa kweyinki. Izinto ezithinta i-viscosity ye-inki esekelwe emanzini ikakhulukazi zihlanganisa izici ezilandelayo.

(1) I-viscosity ye-binder. Ngoyinki osebenzisa umbala ofanayo, i-viscosity ye-binder inkulu futhi i-viscosity ye-inki nayo inkulu.

(2) Ubukhulu, okuqukethwe kanye nokuhlakazeka kwezinhlayiya ze-pigment. Ku-binder efanayo, uma inani le-pigment lifana, izinhlayiya ezinkulu, i-viscosity enkulu, futhi ngokuphambene nalokho. Okungcono ukuhlakazeka kwe-pigment, kuncane i-viscosity kayinki, futhi ngokuphambene nalokho, i-viscosity ye-inki inkulu.

(3) Ukushintsha kwezinga lokushisa. Lapho izinga lokushisa liphezulu, i-fluidity ehlobene yama-molecule ayinki iyanda futhi i-viscosity iyancipha; lapho izinga lokushisa liyancipha, ukuhlangana kwama-athomu kayinki kuyanda futhi i-viscosity iyanda.

Abakhiqizi bemishini yokunyathelisa ye-ink bakholelwa ukuthi i-thixotropy kayinki iyimpahla ye-fluidity ye-inki eshintshayo ngaphansi kwesenzo samandla angaphandle. Emshinini wokunyathelisa, ngenxa yesenzo se-roller ye-inki, uketshezi kanye ne-ductility kayinki kwanda ngesikhathi sokudlulisa, kuze kube yilapho amandla angaphandle enyamalala ngemva kokudluliselwa eshidini eliphrintiwe, futhi uketshezi kanye ne-ductility yalo kuncipha, futhi uyinki uyashintsha usuka mncane uye ushubile, ngaleyo ndlela uqinisekise ukunemba nokucaca kokugqamisa namachashazi. Uma uyinki une-thixotropy enhle, ihambisana nokudluliswa kweyinki okubushelelezi futhi okufanayo futhi ithuthukisa izinga lokudlulisa likayinki.
