invention of the gutenberg printing press
Post a photo of the Gutenberg Press.
What motivated Gutenberg to find a better way of creating books?
Why did Gutenberg experiment with metal type versus wood type?
Post an example of movable type in a type case.
Movable type is the system of printing that uses movable components to reproduce the elements of a document
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"? paper pressed through it leaving text and images on the paper
In the Gutenberg Press, ink was rolled over the raised surface of movable hand-set bloc letters held within a wooden form. The Gutenberg Press is an example of relief printing
Post an example of an intaglio press.
The image area is etched into the plate surface to hold ink, then damp paper is placed on top, add pressure, and then the ink is transferred to the paper.
Post an example of a screen (porous) printing press.
What is porous printing and how is ink transferred?
The image carrier is attached to a screen and then the ink is forced through open mesh areas
Post an example of a lithography printing press.
Drawings or artwork is made on a plate with greasy ink or crayon; then the ink is spread on top, the greasy parts accept the ink
What variation of lithography is used by the commercial printing industry today?
The presses used today are faster, cheaper and can do more than just letters on paper
How do printing presses used today compare to the Gutenberg Press?Describe four-color process printing using CMYK?
Different color ink (cyan, magenta, yellow, and black) can make many colors, when mixed correctly. This color process is best for printing because it uses ink, not light like the Internet.
