Ink transfer in contact-based printing systems, such as flexographic printers, is a significant example of such phenomena and can be adequately understood only when investigated as an FSCI problem. This paper aims to pioneer the study of ink transfer between interacting rollers by proposing a methodology applicable to a wide range of FSCI scenarios. The methodology includes prescribing a small gap where the structures establish physical contact and applying an auxiliary fluid in the gap with a viscosity high enough to prohibit its movement, thereby practically replicating the real closed contact. A Lagrangian conformal mesh approach is employed to maximise accuracy while maintaining reasonable computational cost. Simulations were conducted on a scenario involving substantial deformation of a roller surface and its penetration into the microcavities of the other roller, where the ink initially resides. The results demonstrate different phases of ink transfer between surfaces: pre-contact, contact development, isolation, contact opening, and surface separation, during which ink breakup occurs. The pressure was observed to rise significantly during the penetration phase, reaching a peak value of approximately 1\u00a0\u00d7\u00a0106 Pa. The ink transfer rate was calculated to be 27%, consistent with the relatively lower band of reported industrial ranges. The ink transfer rate was calculated to be 27%, consistent with the relatively lower band of reported industrial ranges. These findings provide insights into understanding and controlling ink transfer between rollers, which can help maximise cell evacuation rates by altering the engraved texture shapes on the rollers. The proposed methodology is also applicable to other contact-based printing systems and broader applications involving FSCIs.<\/jats:p>","DOI":"10.1093\/jcde\/qwaf119","type":"journal-article","created":{"date-parts":[[2025,11,4]],"date-time":"2025-11-04T12:54:16Z","timestamp":1762260856000},"page":"45-59","source":"Crossref","is-referenced-by-count":0,"title":["Study of fluid-structure-contact interactions for ink transfer modelling in a contact-based printing system"],"prefix":"10.1093","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2821-3871","authenticated-orcid":false,"given":"Mehdi","family":"Seddiq","sequence":"first","affiliation":[{"name":"School of Engineering, Liverpool John Moores University , Liverpool L3 3AF ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Phillip","family":"Taylor","sequence":"additional","affiliation":[{"name":"School of Engineering, Liverpool John Moores University , Liverpool L3 3AF ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leon","family":"Newton","sequence":"additional","affiliation":[{"name":"School of Engineering, Liverpool John Moores University , Liverpool L3 3AF ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Sharp","sequence":"additional","affiliation":[{"name":"School of Engineering, Liverpool John Moores University , Liverpool L3 3AF ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4941-5111","authenticated-orcid":false,"given":"Mehdi","family":"Seddighi","sequence":"additional","affiliation":[{"name":"School of Engineering, Liverpool John Moores University , Liverpool L3 3AF ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,11,4]]},"reference":[{"year":"2018","author":"Abbott","journal-title":"Printing Science: Principles and Practice","key":"2026010204363899600_bib1"},{"key":"2026010204363899600_bib2","doi-asserted-by":"publisher","first-page":"1345","DOI":"10.1002\/nme.6094","article-title":"A consistent approach for fluid-structure-contact interaction based on a porous flow model for rough surface contact","volume":"119","author":"Ager","year":"2019","journal-title":"International Journal for Numerical Methods in Engineering"},{"key":"2026010204363899600_bib3","doi-asserted-by":"publisher","first-page":"298","DOI":"10.1016\/j.ijheatfluidflow.2010.06.011","article-title":"Simulation of non-Newtonian ink transfer between two separating plates for gravure-offset printing","volume":"32","author":"Ahmed","year":"2011","journal-title":"International Journal of Heat and Fluid Flow"},{"key":"2026010204363899600_bib4","first-page":"133","article-title":"Experimental research of anilox rolls parameters with raster electronic microscope","volume-title":"Proceedings of the 2nd International Student Conference on Print and Media Technology: Printing Future Days 2007","author":"Aleksashenko","year":"2007"},{"volume-title":"Systematic Variations of Parameters Affecting Waterjet-hull Interaction.
