Printing Press
Printed materials are part of our daily life; newspapers, magazines, and books are just some examples. The printing press is a machine used for mass production of these printed elements.
This machine has become one of the most significant inventions. Before it appeared, monks had written books by hand so just a few people had been able to access information. Only very rich families were lucky enough to have a book, which was usually the Bible.
The ancient Chinese used pieces of wood with symbols and drawings to make books. Around the beginning of 1440, a German man called Gutenberg, who had worked in basic forms of printing, started experimenting with improving the process and finally discovered that using metal instead of wood and blocks with many words could allow people to reproduce texts
In great quantity. The printing press is one of the inventions that has had great impact in the world. After books could be printed in mass quantities, knowledge became available for most people and the first libraries were founded. Since then we all have bought a book.
