| Abstract | In this paper, the effect of the nip force on the ink transfer in gravure printings was investigated. An adhesive force-based ink transfer model was suggested. This model is a function of the contact length between the ink and the substrate. The static simulation of the elastic deformation of the substrate was implemented under different nip forces. The simulation showed that the contact length (L$_{IS}$) was increased as the nip force increased. Accordingly, the ink transfer ratio was increased as the nip force increased due to an increased contact length L$_{IS}$. However, the fidelity of the printed pattern at high resolutions could deteriorate if the nip pressure was too high, especially when the doctoring ratio was greater than 1. Finally, experiments were conducted to verify the effect of the nip force, which showed good agreements with predicted results. The results of this study may be used as practical guidelines in determining the optimal range of the nip force in R2R gravure printing at high resolutions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
