The need of micro precision in printing electronic technology is a new challenge for micro pattern, printed electronic devices and application which use thin film substrate. Gravure roll to roll is considered as a well known thin film technology for printed electronics besides other printing methods such as inkjet, pad printing. However, it needs to be studied more in achieving the micro scale accuracy...
The pattern shape engraved on the gravure printing roll is one of the most important factors influencing ink transfer. This study is focused on the relations between dot geometry engraved on gravure printing roll and the ink transfer during the gravure printing process. The influence of dot width on printed patterns will be demonstrated. Results reveal that as the width of a dot on the printing roll...
The objective of this study is to develop the simulation software for numerical control (NC) machining. This paper presents the visualization and analysis of cutting process in slope machining by using advanced octree method. A software based on advanced octree algorithms has been developed and used as the basis in this study. The suggested algorithm with supersampling techniques in computer graphics...
