Next-generation patterning processes have been extensively studied recently, with a view to replacing the photo-lithographic process and to reducing production costs. For micron scale patterning, the printing process is one of major candidates. In particular, contact printing is more promising in view of the possibilities for mass production. In this process, the motion of the two printing contact surfaces should be synchronized perfectly to prevent slip and unwanted distortion in the surfaces and to make precise ink transfer between the surfaces. In this article, a force-based direct measurement method of the synchronization error is proposed, and the effect of synchronization error on the printing process is analyzed.


The existing system function as a multiple unit like computer setup and printing unit is fixed at different location and an intermediate person will be there to do the printing process. The existing system faces some difficulties like structure is not compact, all the units are installed at a different location, Customer needs 24*7 service, but the service is not available in all the times. The service timing is limited up to the availability of the labor. The Automated pay and use browsing, and printing machine is a type of vending machine which performs 24*7 browsing and printing service. The system can be implemented in the public places, educational institutions etc. The setup works on the time-based control system based on the amount paid as the input for browsing and printing separately. The main controller is the Raspberry Pi which controls and monitors the complete browsing and printing process. The separate coin collector device is interfaced with it to collect the amount for browsing and printing service. A continuous monitoring is done through IoT which helps to monitor the machine 24*7 which provides data like number of printout taken, browsing time.
