Design And Fabrication Of A Printing I Block Machine

Design And Fabrication Of A Printing I Block Machine

Abstract

Parameters on which clear prints depends were exhaustively delved . The study revealed that clear print depends on the impressed pressure the working temperature and the gold antipode print paper life expectation.

Also studies were he manner of dependence of these parameters on prints impressed on wastes of varied consistence. The results of these disquisition were utizlied in the design and fabrication of an functional homemade printing machine using gold antipode distance depositor clear prints were impressed on papers during the new machine†™ s operation.
