Ink was rolled over the raised surface of movable hand-set block letters held within a wooden form.The form was pressed against a sheet of paper.
What motivated Gutenberg to find a better way of creating books?Spending time with his father at the mint, watching goldsmiths and jewelers, and his love of reading motivated him to find a better way to create books.
Why did Gutenberg experiment with metal type versus wood type?Wood cuts were not durable but metal type could be reproduced more quickly once a single mold could be made.
Post an example of movable type in a type case.

What is moveable type?
Moveable type is the system of printing that uses movable components to reproduce the elements of a document (usually individual letters and punctuation).
What is a matrix?
A mold in which something is cast or shaped.
What ink did Gutenberg develop that he used specifically for the printing press?
An oily, varnish like ink made of soot, turpintine, and walnut oil.
What is paper made from? Where did paper originate?
Paper is a substrate made from wood pulp.  Paper originated from China.
What is a "substrate"?
A material that provides the surface on which something is deposited or inscribed.
Who did Gutenberg seek to help with the invention of the press? Close to the end of the 5 years, what happened?
He sought out John Fust, a wealthy bussinessman.  Fust sued Gutenberg, the judge ruled in favor of Fust, and Gutenberg turned over the press, tools, materials, and all 180 Bibles.

Who introduced the printing press to England?
Milliam Caxton introduced the printing press to England.
What was the early form of newspapers?
Trade newsletters were the early form of newspapers.
When was the first news weekly published? What was it called?

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"?
A mark impressed on a surface by something.
Which printing process is the Gutenberg press an example of? Briefly describe the process?
Relief printing is the printing process the Gutenberg press is an example of.
Post an example of an intaglio press.

What is intaglio printing and how is ink transferred?
Intaglio is printmaking.  The image area is etched into the plate surface to hold the ink.  Ink is applied, then rubbed with a cloth to remove the excess.  Damp paper is placed on top.  A press applies pressure to transfer the ink to the paper.
Post an example of a screen (porous) printing press.

What is porous printing and how is ink transferred?
Porous printing is a basic stencil process.  An image carrier is attached to a screen.  Ink is forced through open mesh areas.
Post an example of a lithography printing press.

What is lithography and how is ink transferred?
Lithography is printing from a flat surface.  Drwing, or 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?
Offset lithography is used by the commercial printing industry today.
How do printing presses used today compare to the Gutenberg Press?
Many printing techniques have been revolutionized by the invention of computers.
Describe four-color process printing using CMYK?
CMYK refers to the four inks used in some color printing: cyan, magenta, yellow, and key (black).
