Gutenberg’s printing press did not have an impact on the framing of the United States Constitution.
<u>Explanation</u>:
- Gutenberg’s printing press is a printing device which was invented to enable the standardized printed matter to be mass-produced, primarily text in the form of books, pamphlets and newspapers.
- Kuo states in his research of the 11th century, "Dream Pool Essays," that Sheng's movable characters were constructed from baked clay.
- The ink he used was a mixture of pine resin, wax, and paper ashes, and as Kuo states, Sheng's process could be used relatively easily to print thousands of copies of a text. So Gutenberg’s printing press does not create any impact on forming the US constitution.
