#6 The Gutenberg Press | 1450 AD

What is Johannes Gutenberg credited with?He is credited with inventing the technology of printing with movable type.Post a photo of the Gutenberg Press.How did the printing press work?
Ink was rolled over the raised surface of movable hand-set black letters held within wooden form.  The form was then pressed against a sheet of paper.
What motivated Gutenberg to find a better way of creating books?
He was motivated to find a better way to create books  from spending time with his father at the mint, watching goldsmiths and jewelers.
Why did Gutenberg experiment with metal type versus wood type?Wood type was not durable and they split in the press after repeated use.  New blocks had to be carved for each new impression,  Blocks were discarded as soon as slightly different impressions were needed.  Metal type could be reproduced more quickly once a single mold was made.
Post an example of movable type in a type case.What is moveable type?
Movable type is the system of printing that uses movable components to reproduce the elements of a document.
What is a matrix?
The matrix is something that can be reused so the same character appearing anywhere within the book will appear very uniform.
What ink did Gutenberg develop that he used specifically for the printing press?
Oil-based Ink
What is paper made from? Where did paper originate?
Paper is a substrate made from wood pulp.  It originated in China.
What is a "substrate"?
A substrate is a substance or layer that underlies something, or on which some process occurs, in particular. 

Who did Gutenberg seek to help with the invention of the press? 

John Fust invested money.  Peter Schoffer was hired to help with the project.Close to the end of the 5 years, what happened? 
It Guttenberg could not repay the loan, with interest, after 5 years, Fust would get the press, tools, and materials.
What was the first book he printed?
The Bible

Post an example of this book.

How did the Gutenberg Press impact communication?
It perfected script and made it easier to read.  Books were made more rapidly.  Current information could be shared locally and around the world.  The cost of books decreased allowing more people to buy them.  Demand grew and the population became more literate.  People wanted books written in their own language and a greater variety of books.  Economies became stronger.
Who introduced the printing press to England?
William Caxton
What was the early form of newspapers?
Trade Newsletters
When was the first news weekly published? What was it called?
It was published in 1704.  It was called The Boston Letter.
What kind of press was built in the US in the mid 1800s?It was a cast iron press.

Post an example of a 1930s printing press.
By the late 1930s, presses had increased in efficiency and were capable of 2,500 to 3,500 impressions per hour. What is meant by "impression"?
An impression is a print.
Which printing process is the Gutenberg press an example of? Briefly describe the process?Relief Printing, which is when movable type is placed into the press.  Ink is spread onto the type.  Paper is placed on top.  The press applies the direct pressure needed to transfer the ink to the paper.
Post an example of an intaglio press.

What is intaglio printing and how is ink transferred?Intaglio printing is when an image area is etched into the plate surface to hold the ink.  The ink is transferred when the press applies pressure to the paper.
Post an example of a screen (porous) printing press.

What is porous printing and how is ink transferred?
Popous printing is a basic stencil process.  Ink is forced through open mesh.
Post an example of a lithography printing press.


What is lithography and how is ink transferred?
Lithography is printing from a flat surface.  Artwork is made on the plate with greasy ink or crayon.  Water is applied.  When ink is spread on top, the greasy parts accept the ink; the wet parts do not.
Post an example of a offset lithography printing press.
What variation of lithography is used by the commercial printing industry today?
Lithography is used for most commercial printing.
How do printing presses used today compare to the Gutenberg Press?
The printing process does not require much effort or work.  The Gutenberg Press required a lot of hard work.
Describe four-color process printing using CMYK?

CMYK stands for cyan, magenta, yellow and black.  It is used when printing.
