Utility of plastics cannot be ignored in any aspects of our day to day life. But plastics have also created numerous issues at global level and compelled to ponder over its alternative. Plastic takes many years to get decomposed which is its major issue. So, bio-based plastic has emerged an alternative for the key problems aroused due to conventional plastic. Printing on conventional plastic has been common process to meet our daily requirements. But exploring the feasibility for printability on bio-based plastic is challenge in recent time. Therefore, an attempt to print on bio-based plastic is made in this direction. The major objective of this paper is to study a comparative analysis of solid ink density on Conventional and Bio-based plastics using Gravure process.
