Project Abstract
<p> 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.<br><strong>LIST OF TABLES</strong>TABLE 1 – Experimental determination of pressure for printing 11- Effect of temperature on sharpness of print. 111 – Description of (components) parts and materials use for them 1v- comparison of cost and properties of materials <strong>LIST OF FIGURES</strong><strong>Description</strong>Figure 1 sketch of alternative AFigure 2.
