ABSTRACT

Parameters on which clear prints depends were comprehensively investigated. The study revealed that clear print depends on the impressed pressure the working temperature and the gold foil print paper life expectancy.

Also studies were he manner of dependence of these parameters on prints impressed on sheets of varied thickness. The results of these investigation were utizlied in the design and fabrication of an operational manual printing machine using gold foil sheet depositor clear prints were impressed on papers during the new machineâ€™s operation.
