DESIGN AND FABRICATION OF A PRINTING I BLOCK MACHINE

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 machine’s operation.
