Abstract
The design and construction of a printing block machine is the basis for this project. The parameters on which clear prints rely were thoroughly examined. The study discovered that clear print is affected by impressed pressure, operating temperature, and gold foil print paper life expectancy. Also investigated was the manner in which these characteristics depended on prints impressed on sheets of varying thickness. The findings of these investigations were used in the design and manufacture of an operational manual printing machine that used a gold foil sheet depositor to imprint clear designs on papers throughout the machine’s operation.

CHAPTER ONE
1.1 INTRODUCTION
The other printing innovations and technologies came into being in the 1990s as well as the debut of fresh 3D printer producers and CAD tools. Stereolitho graphy (SLA) systems are sold for the first time on a commercial basis by 3D systems. Additionally, Itzchak Pomerantz et al. and William Masters patents for ballistic particle manufacturing (BPM) and solid ground curing (SGC), respectively, were among the other emerging technologies.
Nigeria has prioritized universal literacy and homegrown technologies in recent years. Printing block machinery, in particular, is severely restricted by the drive toward indigenous technology, making printed materials crucial in mass literacy programs. It is consequently quite challenging to obtain printing equipment from sources other than our boards.
Therefore, it would seem necessary to produce printing equipment locally in order to decrease the financial burden on the mass literacy effort. This feature made it possible to conceptualize and create this inexpensive yet effective printing device using only local materials and technology. The design and manufacture of the current machine, which is highly helpful in the printing of various goods like paperback books and cards, is anticipated to inspire and advance the design and manufacture of other machines intended for similar purposes and based on local technology and resources.
1.2 LITERATURE REVIEW AND DATA COLLECTION
Both the public and school libraries lacked any printed works that dealt directly with printing technology. The only publications accessible were commercial newspapers promoting the goods of foreign corporations, which were seen to be of little or no relevance, and volumes on the history of “Types.” However, a visit to the government printing press provided us with the chance to examine the “types” that were offered and the fundamental workings of the enormous printing (blocking) machine with regard to the “Types,” and from there we were able to determine; The effect of temperature on the amount of gold deposited from sheet (sharpness of print )
- The effect of life time on the gold foil sheet depositor.
- The effect of pressure on the amount of gold deposited from sheet (sharpness of print )
- The effect of size of ‘types’ on the sharpness of print (amount of gold deposited )
Definition:
Types : These are the characters or alphabets that forms the letters.
Print :- This is the mark or impression produced on paper due to the types. Gold foil sheet depositor :- is a thin rectangular cellophane sheet coated with gold compound.
- EXPERIMENTAL DETERMINATION OF PRESSURE FOR PRINTING.
The print there must be impact force between two surfaces on e of which contains the ‘type’ and the other the paper on which print will be made. The force produces the necessary pressure for printing.
Consider alternative ‘B’ of the possible design solution. Impact force is due to the acceleration of mass of moveable plate and rail against the stationary letter box located on the element box. The pressure for printing is impact force for a constant surface area
Impact surface area the pressure varies with variation in the impact force. Similarly the impact force varies with the mass and acceleration. But the mass is constant and equal to mass of rail plus mass of moveable plate hence only the acceleration varies. Therefore in this experiment effort has been made to determine.
- The pressure required to print clearly on thin cellophane sheet without perforating it.
- The pressure required to print clearly on paper of average thickness without perforating it
- The pressure required to print on cardboard sheet such that very sharp prints are obtained by varying the input acceleration
Materials: very light cellophane paper, paper back of higher education exercise book ceiling sheet (card board) silver sheets,
Apparatus: Election- speed printer machine
Definition: The electronic speed printer machine is a motorized electronic motor. It has a device for varying the acceleration the current input can varied hence the heat generate and therefore the temperature varied.
Method: the acceleration is varied keeping the temperature and surface area of impact constant. Already the striking mass is constant. The following values show the accelerations at which sharpest prints were obtained without perforation of the materials after several trial. The corresponding forces and pressure are also shown.
