Horizontal partitioning splits one or more tables by row, usually within a single instance of a schema and a database server. It may offer an advantage by reducing index size (and thus search effort) provided that there is some obvious, robust, implicit way to identify in which partition a particular row will be found, without first needing to search the index, e.g., the classic example of the ...
The global spread of the printing press began with the invention of the printing press with movable type by Johannes Gutenberg in Mainz, Germany c. 1439. [1] Western printing technology was adopted in all world regions by the end of the 19th century, displacing the manuscript and block printing .

When printing at 150 lpi, traps are usually between 1/150 and 1/300 inch (0.48 pt and 0.24 pt, 0.16 mm and 0.08 mm). These values are usually multiplied by 1.5 or 2 when one of the colors is black. The trap is not visible since the lighter color is spread underneath the—almost—opaque black.
The invention of the printing press revolutionized communication and book production, leading to the spread of knowledge.

A printing press was built in Venice in 1469, and by 1500 the city had 417 printers.
