What is moveable type?
Moveable type is the system of printing that uses moveable components to reproduce the elements of a document (usually individual letters and punctuations). Lettering was more uniform.

What is a matrix?
Hard metal punch is hammered into a soft copper bar, creating a matrix.Then, placed into a hand-held mold. Piece of type is cast by filling the mold with molten metal.
The matrix can be reused so the same character appearing anywhere within the book will appear very uniform.

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"?

Which printing process is the Gutenberg press an example of? Briefly describe the process?Relief printing 
Intaglio
Porous
Lithography







Post an example of an intaglio press.


What is intaglio printing and how is ink transferred?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 pare 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?Basic stencil process. image 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?Printing on a flat surface. Based on the concept that oil and water do not readily mix.
Drawing, or artwork , is made on the plate with greasy ink or crayon. Mater is applied. When ink is spread on top, the greasy parts accept 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?
Most commercial printing is printed with a similar form of the lithography process called. offset lithography.

How do printing presses used today compare to the Gutenberg Press?


Describe four-color process printing using CMYK?
